This company had serviced my home before, and when it came time to provide me with a contract for the current heating season, the guy who came to the house said the company would no longer take responsibility for filters which were not purchased from them. Their price is triple what they can be bought for. I had to sign a disclaimer that I would not hold them responsible for the filters being "sucked into" the system. They also charged me $150 more than in previous years, stating that my boiler was an extra zone. Their contract, when referring to a "system" already included a boiler or burner. When the mechanic left, after checking my system, and installing my filters and my water panels for humidification, I discovered we were not getting nay humidity. I called in another company, and I watched as he pulled the covers off the humidification units - the panels were installed backwards, and the mechanic had bent them, in order to shove them into place. This guy also showed me that the humidification for one unit was improperly placed into a cold air duct, and I would not get enough humidity. I checked this out on the manufacturer's site, and he was correct. This company also wanted to charge me $1200 more than anyone else was getting for a new central AC condenser. Stay far away from this company. They lie, they charge for things which are not legitimate, and they do not do proper work.
