Greater Niagara Sheet Metal Inc.

The guys who installed my AC and furnace are great.I am satisfied of the work they have done.Paul explained to me every detail before and after the installation.He was very pleasant in answering all my queries as I am not familiar with the equipments in the house as we don't have equipments like these in the Philippines.I feel safe and contented that they were installed properly and up to the standard. I am happy too that I have a new thermostat installed in my living room from the basement and they did a good job as well because it was not easy to install it because of my finish basement.I am satisfied of the quality of their work and I highly recommended Greater Niagara Sheet Metal to everyone especially to all Filipinos.

Greater Niagara Sheet Metal Inc. did an excellent job in installing our new A/C, furnace and kitchen vent. They are reliable, fast, affordable and best teamwork. We would definitely recommend the company to our friends, family members and co workers.

A big thank you to you guys.

Great experience. Efficient and on time appts. Friendly and knowledgeable staff. Answered all questions and concerns I had about the work done. Highly recommend this company.

After an abundance of research of companies who install duct work/Furnace/A-C we got 3 quotes for the scope of work, we settled on Greater Niagara Sheet Metal Inc. for our installation and we are very happy with the result. Committed, professional, timely and compassionate are the best words I would use to describe our experience with John and the team. They did what they said and how they said they would do it. We're in full renovation mode in our house so access was pretty good and the workmanship has proven to be very good. I would and have recommended Niagara Sheet Metal Inc. to other homeowners.

We have used GNSM for all of our HVAC needs for the past several years. John has done our AC unit, repaired and serviced our furnace, installed a new gas fireplace and gas stove and range hood. He also did new duct work for an addition. He gives great advice and the work is outstanding. He is honest and stands behind his work. He will make sure you are happy with everything or he will make it right. He and his employees are trustworthy and I have had no problems having them in my home even when we are not there. He is the best and we would not consider anyone else.

The guys did a great job and Paul D. was great to work with. Very respectful, honest and he really went above and beyond. I'll work with him again.

John and the team did an amazing job. They were quick, professional and affordable.

There customer service was also a highlight of their company.

I highly recommend their services to anyone that needs renovations done in their home.

These guys are great, reliable and professional. They know what they're doing and they do it right. I recently moved into a new build and while they were installing a new air conditioner they notified mistakes on our duct work that our builder had made! We called our builder and got them fixed right away.

Not only did they do a fantastic job installing a new AC quickly and efficiently but they also saved us headaches down the line by politely pointing out things the builder has missed.

Highly recommend these guys!

After receiving quotes from several companies we decided to go with Greater Niagara Sheet Metal. The estimator Paul was very knowledgeable in his trade and was very professional in that he didn’t over complicate or try to push sales. He was very pleasant and took the time to answer all of my questions and worked with me to address any issues with my current system.

The installation went flawlessly, they were able to install the gas furnace and AC in one day, as well as address several dated emergency gas shutoffs, run a gas line for my BBQ, amend an incorrect takeoff at the trunk end. On top of that they replaced the exhaust duct for the gas dryer because it was caked in lint and was a potential fire hazard. Brian and Matt were both respectful and efficient in their work and took the time and care to avoid potential issues and to cleanup after themselves.

I am very satisfied with the quality of their work as well as the timely manner in which it was completed and would recommend Greater Niagara Sheet Metal to anyone.

Paul and John responded quickly and arrived on time. They produced a design document to be used as part of my permit application for a new extension to my home. Also included was a quote for the work to be done. A pleasure working with them!
