After having our A/C fail in our new (older) home, I called Home Comfort to see if they could figure it out (it was hot outside and inside). They came over right away and diagnosed the problem quickly - the A/C unit had never been hooked up to the thermostat, the unit was old (we knew that part), leaking freon, and although they offered to try and get it going, we opted for a new A/C and furnace (original with the 1953 house). They came back to install within less than a week, and were pleasant, helpful and very reliable. They have been back for a follow-up, and were again excellent to work with. I would not hesitate to recommend John and his company - London owned and operated for more than 20 years.
