Nasa Heating & Air-Conditioning Services Ltd.

Excellent service. Very happy with the overall experience with NASA. Thank you!

I am very pleased with the professional services Amit Gupta, Nasa Heating & Air Conditioning provides.In January 2019, when my thankless water, not from his company, froze and broke, he responded promptly to my call for help. Over the phone he directed me on how to turn off the water supply to the tank. I could then turn the house water back on for my family use. He informed me of replacement option and I chose the type of tank I wanted. They installed it in a timely manner, worked quietly, diligently, and cleaned and tidy up. Days later, he followed up by phone to find out if the tank was working well and that I was satisfied with it.

I will continue to hire this company for my HVAC services.

Amit seems to know his stuff and completes the job.

I do find his rates on the high side.

I was very pleased with the service provided by Amit. He was informative, professional and explained everything he did. His work was neat. He was on time. He walked me through what he did and also fixed a couple of things that were not done properly by another recent contractor. I would highly recommend him and his company.

We got tankless water heater. Amit and his team did excellent job. Me and my family very happy with work of NASA HEATING & AIR CONDITIONING. I’ll use their services and recommend others.

Amit was very knowledgeable on what the problem was and the best way to fix it. The cost was to fix was expensive, but Amit was honest about the cost and stayed on budget. No hidden cost. Will definitely use him again.

My Navien heater was installed by OEG. It quit working when I had a houseful of guest during a weekend. OEG was not able to provide immediate service. I am glad I called Amit at NASA. The service was expensive but I believe it was worth it. He replaced the electrodes and did descaling, which is supposed to be done every few years.

He also pointed out some serious deficiencies in the original installation, and offered options which I will consider at a later date.

Last December I asked Amit for a Lennox but he insisted that Keeprite is a better furnace, and he asked me for a deposit during his first visit or I have to pay him $150 extra, I paid him $1500 deposit and after some research I tried to cancel his service but he told me I'll charge you $1200 without installation !!! He charged me $3500 for a G9MXT which has a 5 years warranty. After installation he told me a $150 yearly maintenance is a must otherwise the warranty will not be valid. Furthermore, when I asked for an invoice he told me if you want an invoice for the furnace you need to pay extra 13% tax ! so he did not give me an invoice ! After a year I asked him for free maintenance as the price of installation was high for a Keeprite, he told me you agreed on the price and I'll hang up the line. Later I was offered to install Lennox for the same price ($3500) for my small house and found out that none of my friends do a yearly maintenance. The problem with Amit not only his high charges, poor quality devices, but also he has poor customer service/communication skills. Most of the customers who gave him good scores now will face troubles with their devices later on and they will be under his mercy for maintenance for the life of the product. Here is a link of unbiased reviews for Keeprite: https://www.furnacecompare.com/furnaces/keeprite/reviews/

Nasa Heating & Air-Conditioning Services Ltd are extremely professional, followed up and kept me informed throughout the whole job, and were very honest throughout the whole process. Overall, a great experience.

Service was professional, on-time and reasonable. After inspection advised on what needed to be done. Provided price and cost information. The job was done on time and left the place clean.

Amit and Ross did a great job. Prompt in replies. Followed up even after work was completed. Very meticulous in performing work making sure everything is done correctly with no leaks. Pricing on par with other quotes. I've used NASA twice now and have been pleased.

Amit was incredible! He worked quickly, was very knowledgeable on the product, and found a solution right away. Amit is honest and extremely reasonable. Would highly recommend him and Nasa to anyone having tankless water heater issues, or looking to buy new!

Thank you Amit!

I really like the fact that Amit immediately answered my call on the weekend to hear my issue with a leaky water heater. Amit stopped by to evaluate and confirm that the water heater had in fact failed. The next day he arrived with a replacement water heater that he and his assistant promptly installed. They were extremely courteous, clean and efficient in their work. I highly recommend Nasa and will use them in the future with no hesitation.

The job was done well and on time. Amit was courteous, professional and knowledgeable. He even took the time to follow up with us. I would recommend Nasa Heating & Air Conditioning Services Ltd.

Propmt service. Value for money. Perfect Job. Fully satisfied.

Amit has served our AC and Furnace needs at two different homes over a 12 year time frame and he has been unfailingly prompt, affordable and polite. He's been there for every emergency call, and responds to texts within minutes, if not seconds! We have recommended him to friends and will continue to do so.

My air conditioner stopped working on Saturday night during the hottest stretch of the summer. On Sunday morning I called Amit at NASA and he was at my home within two hours affecting the repair. He quickly diagnosed the problem, a blown capacitor had caused the compressor to stop working. With the capacitor replaced and the unit working he washed off the evaporator coils and checked the gas level in the system (and topped it up) to ensure my AC was running efficiently.

Very fast, thorough and friendly service! Amit is very personable and was happy to explain what he was doing at every step in the repair! Great service!

NASA Heating and Cooling did an outstanding job of helping me with the procurement, and installation of a new Air Conditioner. The NASA Team is highly knowledgeable, deeply experienced, and very customer-oriented. They were highly recommended from a friend, and did a stellar job of exceeding all of my expectations on all fronts. I am eagerly looking forward to working with the NASA Team for all of my future Air Conditioning, Heating, and Hot Water Rental needs. What differentiates NASA from other organizations is their unmatchable customer-orientation, deep expertise, and high responsiveness. Mr. Amit Gupta, leads this terrific organization, and goes out of his way to ensure his team delivers everything which was promised, and even more. For example, Mr. Gupta didn't charge for extra material, which was required as my house size is relatively larger compared to others in my neighbourhood. NASA's quotation was the lowest among 6 suppliers I had considered, and they delivered on budget, and on time. Unlike other organizations, NASA doesn't cut corners to make extra profit, and delivers the best quality. Mr. Gupta himself is a highly qualified engineer, and is a veteran in this industry. Mr. Gupta can accurately, and quickly diagnose the root cause of an issue, which is key to troubleshooting it in a timely and cost effective manner. He has built a high performing team - nimble and responsive in troubleshooting issues in a timely manner, which is a critical requirement, when an A/C or Furnace fails. Last but not the least, NASA provide an outstanding after sale service support. I highly recommend without any hesitation NASA Heating for all your A/C, Furnace, and Hot Water Rental needs.

Amit was wonderful and patient. He explained the problem not just with his words, but by showing me things about the "dead" motor. This was all uncharted territory for me. I've been a homeowner since 1986 and this is my third house, yet I've never had to have a furnace motor replaced before. I will not hesitate for one second to recommend Nasa Heating & Air-Conditioning Services Ltd to anyone in future.

Thanks Amit!

Amit was absolutely top notch in every aspect including quality of work but additionally attention to customer service. He accommodated my emergency situation (I had no hot water) when he was very busy and installed teh tank on a Sunday with no notice.

He went one step further and argued with the previous tank company (a tankless hot water heater I had installed by another company 2 years earlier), ad was able to get me a replacement tank for free. It took him 2 months of arguing with the manufacturer on my behalf but he never gave up and eventually he convinced them that they were at fault.

I didn't believe him when he said he would fight for me, because I guess I am jaded by all those other service people who just don't care, but he actually did it and he has restored my faith in people.

Amit is a gem and I wouldn't hesitate to recommend him to anyone.

Mr. Amit, Thank you for an excellent job. I am very satisfied and it would be my pleasure to recommend your services.

I found Mr. Gupta to be honest, quick to respond and highly efficient . He is knowledgeable and his followup is professional.

Amit and Ross were nothing less than amazing. They were on their way home for the day when I called but they came anyways. It took them until the early morning to find the multiple leaks so we could get our gas back on and sleep safely. They were extremely thorough and professional. They communicated well and made damn sure everything was resolved to our complete satisfaction before they left. I wouldn’t recommend anybody else but Nasa.

Nasa Heating & Air-Conditioning Services Ltd. was referred to me through a family member. After my old furnace broke down, Amit Gupta was quick to respond to assess the problem. While fixing the unit was an affordable option that was available to me, Amit fully explained the options of single-stage and double-stage furnaces so I was at least aware how the heating efficiency in my home could be improved. At no time did I feel pressure. It was simply a matter of gaining knowledge and making an informed decision. I decided to buy a new Keep-Rite double-stage furnace. It was installed the next day. I was already considering replacing my outdated humidifier as well, so I proceeded with that as well. About three weeks after the fact, it's obvious the investment was worth it. The new furnace is much quieter, and every room in my home is very comfortable (Amit also fixed the position of the duct blowers after a duct cleaning company messed them up, cutting off air to a 1/3 of my house). The humidifier is also excellent and the updated feature of a digital readout for humidity levels removes any guesswork in setting the levels. I highly recommend Nasa Heating & Air-Conditioning Services Ltd. if you want to make an informed decision without feeling pressured to buy something you don't really need. I'm very happy with my decision.

Amit was very professional in all interactions with us. Was very prompt to respond to our call and follow up calls in the decision process.

Took the time to explain all the options we should consider.

I would have to say that Amit's customer service, workmanship and follow up is top notch.

We would highly recommend his services

When my water heater started leaking, I called Amit Gupta of NASA, who was recommended by the manufacturer and whom I already knew, because he reinstalled a badly installed heating & A/C unit for me last year. Amit came right over to assess the situation, saw that the heater was rusted beyond repairing, and within two days had ordered, received and installed a new one for me. The installation took about 2 1/2 hours, including removing the laundry room doors so he and his partner could remove the sink, washer and dryer, cleaning the room prior to putting them back, and completing the installation.

I had on several occasions service done to my furnace and water heater by another company and let me tell you this...I am so impressed and will never call another company to deal with none of my Furnace, AC, water heater, other than Nasa Heating and air conditioning, I was so impressed with the workmanship, explanation, they did take their time to explain step by step.

Nasa also took the time to call me two days in a row to verify that things were ok. I am very happy for making the call to Nasa they really go over and above to make sure things are done the right way. Very happy indeed.

Needless to say Nasa will be the company I deal with.

Keep it up because now a dats its hard to get the service you guys offer.

Thanks,

Tony

Mr. Amit and his team installed Furnace at our home. The installation was neat and pricing was great compared to others. We appreciate your honest opinions while selecting the right kind of furnace within our budget. Our home is comfortably warm. Definitely recommended if you're looking for Furnace installation in GTA.

The service provided by Nasa Heating, Amit, was outstanding. From my original request for service to job completion I was impressed with the prompt response, efficient and quality work. I will have no hesitation to recommend Nasa Heating and will use them for any future Heating or Air Condition needs.

Amit Gupta from Nasa Heating & Air Conditioning was prompt in returning our call and came out very soon to see the faulty air conditioning unit. He provided competent, professional and reliable service on the hottest day of the year when we needed his help the most! Amit is cheerful and friendly and followed up with phone calls in the days after to make sure everything was working well. We recommend him highly for his quality of service and expert help.

We had our old air conditioning system replaced by Amit Gupta - Nasa Heating & Air-Conditioning Services Ltd in June 2017. The service is quick and great! The work is professional! and the installer is friendly! We are very delight with our purchase, and will definitely recommend Amit and Nasa to my family and friends!

Amit Gupta is a pro who came prepared with the tools to diagnose the problem and fix it. He was available within hours of my call to him. Our air conditioner had stopped cooling, and instead of just advising that it be replaced, (it was new in 2009, Amit took the time to figure out what was wrong and fix it. I called him in the first place because he had a number of favourable reviews from satisfied customers, of which I am now one. I will be counting on him in the future to deal with our gas furnace and water heater as well as the air conditioner.

November, 23 2017:

Amit did the same kind of fine work replacing our gas water heater as he did in providing furnace service and central air conditioning repair this year.

Highly recommended as a skilled and knowledgeable professional.

I first met with Amit. Super polite and very informative. He answered all of my concerns and questions. He informed me that a new tank will be needed being the old tank had a lot of corrosion all over the copper pipes as he showed me... Or try to fix it, with no guarantee that it will work for a long period of time.

We opted for a new tank (our home had no hot water). Within 24 hours we had a new tank installed and had hot water again.

I can not praise Amit enough for his amazing customer service and the short amount of time to come back and install the tank.

Amit has since then, called to make sure we had continuous hot water and of all was well and if Ever needing to come by and check on the boiler, do not hesitate to call Any time, day or night.

I HIGHLY recommend using Nasa Heating and Air Conditioning... Great Service and a Great Company!!

Thanks so Amit!!

I liked the service I received from Amit. When I called Amit because our water heater was cold, he scheduled our appointment the same day. He came to our house on time, inspected the water heater and discussed our options. We decided to replace the water heater and, with Amit's help, we chose the size we felt best met our needs. The replacement appointment was scheduled for the next day. Instalment went smoothly and Amit took away the old water heater. He called back that night AND the next morning to touch base and make sure that the water heater was working well. He was also available by text. I believe the price was fair.

Great service by Amit Gupta! Friendly, fast and efficient!! Highly recommend him. ;)

Amit was very responsive, arrived within 2 hours of my call and corrected the problem I was having with my whole-home humidifier. The control console had to be changed and he was able to get it from the supplier within warranty.

This is not the first time I had to call him for service at my home (I had furnace issues last year) and he has always been quick to attend. Amit is very professional and knows the stuff he's doing.

I'll not hesitate to put in a referral for him.

I had my furnace installation completed by Nasa Heating & Air Conditioning several years ago and have had yearly maintenance service provided. All work is carried out completely and efficiently and explained in an understandable manner.

Amit is a super professional tech and very courteous and knowledgeable.

My experience was a very positive one.

I originally contacted Amit in late summer to get a quote on an installation. However my current financial situation made me want to try and squeeze one last winter out of my furnace despite several other professionals warning me I would be lucky if it lasted that long. Amit contacted me in January just to see how things were going and we mutually agreed to speak at the end of April to proceed with the job.

I believe it was exactly six days after this conversation that the bearings on my fan motor started to go and make a horrible grinding sound whenever my nearly 15 year old furnace was in operation. I contacted Amit in a bit of a panic and he came over within 90 minutes to inspect the situation.

He set me up with a good energy auditor by the name of Nelson who I'd also highly recommend. Nelson was able to do the energy audit the following day and Amit was able to install my new furnace the day after that.

Amit answered all my questions in a straightforward and honest manner (and I did have a lot of them) and finished the job in 3 hours then stuck around for an extra 90 minutes to make sure everything was optimized and working properly. Any other contractor would have probably left as soon as it was done to hide all the corners they cut during the process. With Amit, there were no cut corners and he improved several aspects of my existing equipment himself or made recommendations how to do so which I've followed and noticed a difference already.The next morning Amit called me to see how everything was running and to check for any problems even though there were none.

The personal touch and his 30 years of expertise make him one of the best, if not the best, furnace installers in Peel region and considering some of the stories I've heard, I really lucked out in this situation. I would highly recommend his services.

Mr Amit Gupta found that our heat/air conditioning unit was no longer able to provide heat during a very cold spell this winter. The perfect fit was ordered and he called several times to check to see if we were comfortable while the new unit was on order.

Mr. Gupta also suggested we upgrade a switch on our electrical panel to provide maximum efficiency and comfort and answered all of our questions.

Finally, he contacted us to ensure our satisfaction and comfort were met.

We recommend him to others and would use his services again.

For my new house, Nasa Heating supplied and installed the new A/C and Humidifier. They also offered to maintain these along with the builder installed furnace.

The first winter after we moved in, we found that the heating had stopped working. We called Amit at Nasa and he responded immediately. He walked me through few steps on the phone to identify the issue. We were able to start the heat. However he still came the next day to do a check up and found that the furnace venting (Exhaust & Air Intake) pipes were undersized. He quickly changed the pipes and we have not had any problem since. He also helped us claim the repair cost from the builder.

Amit calls me every 4-months to remind me to change the filter and to check that everything is ok....absolutely great customer service.

Last week my humidifier stopped working due to an issue in the water solenoid valve. The experience with Nasa was the same...quick response, diagnostic over the phone, follow-up with a visit. Completely painless!

I would highly recommend Nasa Heating and Air-Conditioning!

Last week my humidifier stopped working due to an issue in the water tank valve. The experience with Nasa was the same...quick response, diagnostic over the phone, follow-up with a visit. Completely painless!

I would highly recommend Nasa heating and Air conditioning!

Amit is a true professional. He will always do the impossible to help as fast as he can especially when an emergency happens like a broken AC during summer or repairing the heating system when it's cold in the winter. I appreciate Amit's honesty on repair options when the AC/Heating system breaks down.

Thanks again Amit!

Amit just left my place after fixing the capacitor in my unit. First class gentleman. He arrived almost immediately, took time to understand my unit's history, asked important questions to understand the issue, and then began diagnosing the problem. Within an hour, I had my unit up and running.

In comparison to all the other company's out there, I believe I found a gem. While the others answered the phone somewhat dismissively, tried to overcharge me - almost double in price in comparison to Amit's prices - and largely lacked any knowledge about their organization's services, Amit was the exact opposite.

Such a pleasure to meet someone caring - a big part of doing good work ... at least in my books!!

Mr. Amit Gupta knows gas! I called him to connect my new gas stove and he saved my family's lives. He noticed a leak in my gas line and had me deal with it right away. He then noticed deficiencies with my newly installed furnace. Thanks to him all is fixed now and we can sleep with peace of mind. He was very pleasant and gave expert advice. I was so pleased with him that I gave him my next job, to supply and install a new tankless water heater. This thing works great. His service is A-1.

Amit is a very knowledgable and committed professional and we had a great experience with him installing a new furnace and tankless hot water system. Our house is much more comfortable now.

NASA Heating and AC (Amit Gupta and his team) are real pros. They were timely, courteous, tidy and thorough. Fairly priced, though not the cheapest technicians, but you get what you pay for and that's a job done right - and when it comes to critical systems in my home that's what I want.

After my call, I had Amit at my door within the hour. We discussed repair and cost but decided to go with a new tankless water heater. The pros and cons were well explained to me and Amit was very professional, organized and polite. The tankless water heater was installed the very same day. All the work was very well done, as I watched what was being done. As I watched I was able to ask questions about the product. Other chit chat as well was very friendly and appropriate. Once the work was completed all was cleaned up and the old tank taken away. I was reminded that if I had any concerns to contact Amit and set up his contact information on my phone. Very quick service done in a professional manner. The way we hope all service would be.

I had an issue with my hot water tank and found NASA on the Internet. Amit provided fast and accurate service at a fair price. When my A/C aged out I again called NASA and I had a new Air Conditioner quickly in the middle of a heat wave. While installing my A/C Amit noticed some "setup" issues with my furnace and after correcting we had move better air distribution in the house. I will call NASA in future for further HVAC issues.

Amit from Nasa Heating was a pleasure to deal with. He came to our home in the evening to meet with me and my husband and was able to replace our broken water heater the next day. Professional, thorough, highly recommended.

A friend referred us to Nasa Heating and Air Conditioning when we awoke to find we had no hot water. I called Mr. Gupta at 8:30 am and he arrived to our home very quickly. He diagnosed the problem and dealt with the warranty department to have our system replaced. The new system was installed and running a few hours later. Mr. Gupta is very experienced and knowledgable and I would highly recommend his company. It is great to know if we have any problems in the future he is a phone call away!

Nasa has been the provider of our HVAC needs for several years and they continue to surprise us with regular followups, and excellent advice and service. We have used them in two different homes, and have referred them to several friends, all of whom appreciated the same work ethic and professionalism that we did. An excellent company that I recommend with pride.

We had an unique problem with our heating system that had been looked at by other companies who would change parts, and charge us without fixing the problem. When Amit came he realized this was unique, and got hold of technical support from the manufacturer to get the job done right the first time...Well Done!

A visit from Amit is a good day. He's efficient and cheerful, and strives to solve any issues in a timely fashion.

Great service! I have been using Amit for all my Heating and AC needs since I got my house 10 years ago. He sold me and installed my AC unit and it was such a great price/speed my neighbours got one as well. Never had an issue in 10 years since. Twice since I have also had issues with my Furnace and Amit was able to come right out (once when I was worried and it was very late) to fix it. He never left me wondering about costs and always completed the work in the time he estimated for the cost quoted or less. Will continue to use his service and not look elsewhere.

Listened to our wants and needs. Gave appropriate recommendations. Revisited before installation to re review details. Day of installation, prompt, protected my flooring, no mess for me to clean up and stayed within budget. Did follow up phone calls to ensure we were happy .

This is the second time my partner and I have used Nasa Heating and Air-Conditioning. Both times, Amit has been professional and completed the work in a timely manner. Both houses he has replaced my furnaces in required some creative thinking with regards to small spaces and ensuring the work meets the building code. Amit knows his HVAC and I would happily recommend him.

We have been working with Mr Gupta since the last 12 yrs . He has been very professional , dependable . We would recommend Mr Gupta to everyone

One of the most dependable contractors I have dealt with over the years. This company can always be counted on to fulfill their obligations on all projects. Their commitment to customer service, professionalism and quality are second to none

Amit, who owns Nasa Heating was professional and prompt . Came on time with his installer and completed the installation by end of the day. He supervised the installation and left only after it was completed. He tested the system before leaving. A week after the installation I had reported an issue and he has promised to attend to it immediately. He responds to your phone call and email promptly and therefore can be reached quickly when needed.

The installation removed an old noisy inefficient furnace and replaced it with a new quiet efficient furnace with cold air intake and exhaust now through the side of the house instead of the roof. The installation and removal went flawlessly and completed without errors within a day. The new intake and exhaust were positioned perfectly and are appealing to the eye. Since the job was completed, the air conditioner has been used all summer with no problems and we have now been using the furnace with no problems. The service and quality of work was very professional with several follow up visits to ensure our satisfaction and more than exceeded our expectations. The service professionals answered all our questions and worked very dilingently to complete the job in one day.

I have had the opportunity to use Amit's services on three installations over the past year and have been very pleased by his ability to come up with creative solutions, execute a plan and provide great follow up.

He is a perfectionist who goes out of his way to make sure things are done with the utmost professionalism.

I highly recommend him!

Amit was a pleasure to work with.

He and the men he worked with were courteous and,hard working . They were punctual . Amit always explained waht he was doing and who things worked.

They left our basement and house so clean you didn't know that htye had removed a 50 years old furnace and a 23 year old air conditioner that they had to carry through our house as we have only one entrance.

I highly receommend Amit Gupta owner of Nasa Heating . Elaine Lithwick

Amit has been our exclusive HVAC service provider for the past several years, and we give him our highest recommendation. He is extremely knowledgeable, prompt in giving timely service, and his work is always reasonably priced. He has been available on short notice, and will even attend on weekends. A big plus for us is that Amitl services attic air conditioners, and did this in the heat of summer of 2011.

I live in a very large home that is challenging to keep comfortable, both in the winter and summer as well. I found Nasa Heating to provide excellent advice for the specific conditions of my home. They did the work they claimed they would, for the price they quoted and at the time they committed to. In all aspects, they were professional. We have used them to service our equipment, and they continue to give us good advice about our comfort.

We have used Nasa Heating to replace 2 furnaces, and 1 air conditioner. They have helped with humidifiers and even helped with our fireplaces.

I have referred Nasa to our good friends who have also found them to be a professional company that is easy to work with.

We hired NASA heating to install a new furnance, ac and humidifier in our residence.Overall, a very positive experience. Amit Gupta of NASA Heating and Airconditioning was helpful, knowledgble and courteous, I am also impressed with his follow up and after service. I would recommend his services. We will be using him for getting furnance upgrades in our rental properties.

We have been thrilled with the ongoing service we've received from Nasa Heating and AC. Amit is always responsive, courteous and extremely professional. He always provides cost effective options, and takes phone calls day and night. When we've had emergencies, he's been there to solve the problem. When we've needed new equipment, he's sourced and installed on time and on budget. In short, Nasa is all about service. They are the best.

Best , most informative and thoughtful contractor it has ever been my pleasure to deal with.

He planned and thought ahead, saving me untold grief when events might happen in the future( which did occur in one instance)

I would very highly recomend NASA heating, and I personally use them at my home and office, even though I am far away.

Amit was recommended to us by 3 different neighbours who were pleased with his services. He made a special point of doing our work earlier than planned due to the extremely hot weather we were having at the time. This was very much appreciated.

We are very pleased with the results.

our air conditioning system finally crashed this summer.....i called several contractors but finally settled on mr. gupta...who was eager to assist, competitive in price, extremely knowledgeable and quick to respond to any questions.....as well we had installed a new furnace 3 years earlier...but there was a problem with its installation which mr gupta brought to my attention.....he called back after the job was completed to be assured i was satisfied......this does not happen very often these days.......i have been a home owner for 35 years......very good service....

We would recommend Amit. He was very knowledgeable and professional. The service and price he provided was excellent.

Purchased furnace and AC from Nasa. I dealt with Amit who was knowledgeable and easy to communicate with. I am very pleased with the installation. Everything is tidy and professional and working well. (although its only been a few weeks) Nasa's quote for the furnace was unique compared to several others in that they recommended a furnace with significantly lower BTU than all the others and was the only one consistent with an independent energy audit.
