"I felt that the extra fee was excessive. Other Carrier installers contacted me and agreed to perform the repair for the amount Carrier reimbursed them, with no extra cost to me."

"John and his team did an excellent job. I really appreciate them coming out and saving my family from the cold . We called several companies and all they wanted to do was sell us a new boiler. But, once I talked with John he assured me that he could get my boiler back running and they did just that ! Also they helped educate us through the process. They were very friendly, honest, and hard working. I will definitely be calling John for any future maintenance and yearly tune ups. Thanks again for such an amazing job guys !!!"

"New special order unit came in very quickly, and installation was scheduled for the next day. Old unit was removed and hauled away. New unit was professionally installed with attention to detail not present on the old unit. No damage to walls or floors, and installers used extra measures to prevent outside dirt, snow, and water from being tracked into the house. Very happy with the entire purchase/installation experience."

"Installers were prompt, professional. They took care, using drop cloths inside to avoid tracking dirt.
The system did not work properly when initially installed, so the following Monday, a repair technician came and performed diagnosis and trouble shooting, in contact with manufacturer's rep. He was able to correct the problem and got the system operating.
In addition, to address my concerns that the condenser unit might have been damaged, they subsequently replaced that part of the system to ensure reliability.
I was very happy with their responsiveness to my concerns.
I will use this company again.

"When he returned to install parts, he realized that the fix would not last since the transmission was bad. He refunded the parts money and suggested replacements.

"I was really surprised how smoothly the whole process was. Workers were very professional. On time everyday and cleaned up at the end of each day. Now, I just sit back and enjoy the kitchen I've always dreamed of."

"Started with home energy audit that cost only $59. Sales / tech person was very professional. Performed an energy audit that took HOURS. it was not a rushed job, and he reviewed his assessment with me in detail. That alone was worth the cost. He pointed out spots where there were big heat losses in my home, and what could be done to resolve them. Never pressured me to get the services, but he did show me which things I could do and how much they'd cost, as well as the rebate I'd receive from my energy company. I selected to get my basement rim joist spray insulated, add insulation to the attic, add insulation caps to all the recessed lighting fixtures in the attic, add insulation do attic entryway, and spray and install more insulation around the bonus room above my garage. Each one was an option, and gave improvements to the overall comfort of the house. Work was done in 2 days (they needed to come back due to power issues for the insulation blower). Overall, I'm happy with the results. house is more comfortable and furnace is running less."
