They are a great group of people from Stephanie and Janet in the office and all of the technicians I have used over the years. They are professional, reasonably priced, they are very neat and clean workers. They just installed a new cooling and heating system for me and as always it was a job well done.

We've had great results with Matt and SmartHouse heating and cooling. I highly recommend them for both heating and cooling work.

The day after Christmas we woke up to a temperature of 58 degrees in the house! After I determined that I could not fix it, I called SmartHouse. It was 10 am and Matt was at our house by 11:30. He had the heating system up and running in no time. Go with the guys that know what they are doing.you can't do better.
