I've been a Comfort H&A customer for around a decade or more, and I've not been disappointed in any of the work done by this company. From the day I called till the installation was complete was a matter of 3 days plus a quick finishing job the following morning. I found the analysis and explanation of options very useful, and the install was great--Chris made sure everything was exactly as it should be, even taking a part back to the shop to make sure I got what I had paid for. He did all of this with a pleasant, patient demeanor on a very, very hot and humid day. If you live in the Lexington area, this is the company you want taking care of your HVAC system.
Initially I had a poor running air conditioning system. Trevis Spires did the initial diagnosis, and he quickly saw the likely problem and gave me options to deal with it, including the state of the current system in relation to its coolant requirements (R-22) and the reliability going forward. I decided to get a new system given the age of my current system, and Ryan Woodall went over my situation and options for my home size and configuration. I opted to replace the furnace at the same time (given it's condition and the savings involved in doing both heat and air together). He came up with a plan that was very reasonable, and one day later, Chris Patterson and Josh came for the install. Austin T. was also involved some follow-up work the following day.
