One day last week I returned home from work to find out the air conditioning in my townhouse was not working at all. I contacted my landlady, who told me to call a local company, which I did. This was Monday and the temperature outside was in the 90's. That company told me they could come out no sooner than Wednesday, which was totally unacceptable. I made the appointment but called friends for recommendations on who else to call. When I called Donovan, they said someone could be there in an hour. This was great news of course - but the best part is that a very capable and polite technician from Donovan was at my front door inside of 25 minutes! Brinton diagnosed and fixed the problem that night and I was extremely happy with his work and his demeanor. He was helpful, professional and considerate and really inspired confidence in me that he knew what he was doing. Donovan is a little more expensive but well worth it and I recommend them to anyone and everyone! Thank you so much.
