I think a company has to work hard to be this bad.
We had a full belnap installation of water heater, furnace and A/C. The water heater left us venting carbon monoxide into our house. The furnace left us cold in the winter and they took close to 24 hours to come fix it. the A/C has now been broken for 4 days and they still have not fixed it. Did I mention we have small children? We have only had the system for a little over two years and we had to have it reinstalled once and they have been glacially slow about fixing every problem. And believe it we have had EVERY problem with our system. It has been a complete HVAC nightmare. I strongly recommend if you need a new system go elsewhere. They suck.
