Commonwealth Cooling & Heating LLC

Customer service was good, workmen were knowledgeable, pleasant and were careful not to damage my home, i.e. put plastic carpet runners down to protect the carpet.

Had called another (large name) company to fix the problem. The guy was there for over 2 hours, then said he couldn't fix it because it needed several new parts that would cost $900+! Even though he couldn't fix it, I still shelled out $160 for the service call. Then I called this company! He came over right away, took a look and 20 minutes later, my furnace was fixed! Problem? A clogged hose!!! He did say that my motor would go out eventually, and couldn't say how long it would last. He gave me an estimate, that included labor. When I decided to get the part replaced (I was selling the house and thought I should), I called, they ordered it, it came in quickly, he installed it, and charged me the price he had quoted! Great company, great workers, very knowledgeable, and definitely a great bargain! I would use them again (in fact they did my spring maintenance checkup) and highly recommend them!

Spring 2006. Heat pump condenser failed... Replacement with a new unit went smoothly and all seemed lovely at the time, although the price seemed steep for a Bryant heat pump of routine type, sized for the house's cooling requirements (house is a modest tract house, not large). However in November or December 2006 during a cold heavy rain, the heat pump iced up. Indoor air handler worked fine, and heat had not stopped working, but pump outside got heavy coat of ice. When Commonwealth arrived they immediately tried to tell me I needed to have the indoor air handler replaced, argued for this, in fact. This gave me a very distrustful feeling and I didn't want them back. The next day I found a different technician with a reputation for honesty (replace units only when needed, otherwise, replace parts with proper troubleshooting analysis). His diagnosis was that the condenser and pump itself was OK, and there were no freon leaks (system still properly charged to correct amount), but two problems with parts in the unit: Freon not circulating sufficiently because the flow valve that controls freon movement in and out of the unit itself is one that is known to have a barely adequate or too narrow a fluid opening, and also the defrost timer had failed to operate normally. Icing up typically happens on cold rainy days, when either of these things fail: the defrost cycle, the freon flow, or if freon leak causes low levels of freon. Ironically, the expensive, warrantied main component of the outdoor heat pump was functional and ok... it was just other parts that had failed, though they shouldn't have so early in the heat pump's life. He also checked my indoor air handler unit carefully and it was completely functional and OK. I used indoor "emergency" heat coil for heat until heat pump repair (not as expensive on power as one would think). I would not recommend this company for heating and cooling. They charged top dollar for a unit with cheap or insufficient parts quality, and then tried to argue me into an even more expensive replacement of the indoor air handler when it was OK, and the outdoor heat pump only needed parts replacement. Furthermore for over $2000 expenditure that year, the heat pump should have been trouble-free for several years.

Excellent. This is a small company and the owner provided the initial estimates and beat all other estimates from competitors. Commonwealth's price for the exact line-item work was 20% less than the next nearest competitor. They showed up on time and completed the work as promised.
