It's now been 5 months that we have requested, pleaded, and begged Jeff at Toronto Mechanical HVAC (the original sub contracted installer by Chris Lawrence) to service the deficiencies with their installation of the LG 4 head compressor and 3 new ductless units in our renovation last year.
It started last May when we fired up the a\c during our first heat wave here in Toronto. The house cooled easily and we were happy for at least 1\2 hour.
Then it started. We heard that familiar water dripping onto our newly installed 4" red oak floors. Our first thought was there's another new plumbing leak somewhere behind the walls. However on closer examination, we realized it was not a plumbing problem but a ductless one. Water was actually dripping from the ductless units on to each floor.
Now for those who may not be familiar with Toronto Mechanical, they were the sub trade that Chris Lawrence highly recommended to install not only the LG ductless a/c system but also to install the heating system (new radiators and piping for our boiler), replace the interior and exterior basement sewage drain piping and all the new house plumbing. (Those same plumbers who were carelessly were eating pizza while the water leaked down three (3) floors in house on the night before our move-in .)
Again, as our contractor we expected that his recommended sub-trades would work to at least the building code. Well, they did not. The radiators were not installed properly and did not heat up last Nov/Dec during the first blast of winter. Over a period of eight (8) separate attempts to resolve the radiator failure by Jeff and his team the rads finally heated the house. However, the newly installed recycling pump ( Jeff's solution to pumping up the pressure to ensure 3rd water flow in the rads) began to howl during the night. This was never resolved by Jeff and it remains to be seen this winter if the same problem returns.
By this time I decided to hire a new home inspector who preformed a thorough inspection. And did he find more HVAC problems. They newly installed basement sewage drains were higher than the basement floor and the cement floor had not been sloped to allow drainage to the drains. The new gas piping for the boiler and plumbing had not been properly inspected and tagged. The radiators were actually heating to 180 degrees on the main floor far too high and dangerous. To add real insult, both Chris Lawrence and Jeff highly had recommended that the basement drainage piping be replaced and to include a back water valve and pump because the city would subsidize the cost by up to $1,200. Most important, they would handle all the paper work. They did not and there's no rebate coming.
