"I recently got estimates from a half-dozen HVAC companies for the installation of a full ducted heat-pump system into an home that did not have it - a retrofit. Though I ultimately chose a different company for the project, AireServ really impressed me with the quality of their proposal. I submitted a request on their website and they called me about one minute later. They came out the next morning. They were good listeners and the system they recommended was exactly what I wanted (in contrast to several competitors). They evaluated my house thoroughly, looking at all aspects of exactly how the system would be installed, as well as sizing the system properly with all factors considered. The price they quoted me was not the lowest, but it was far from being the highest. If you are considering a project, I recommend at least getting a bid from these guys."
