The SmartHouse Difference

Because we have filled our ranks with technicians that understand how a whole home is supposed to operate, we can be sure we are providing our customers with the best heating, cooling, and efficiency improvements possible. But beyond our technical knowledge and ability, we want to operate as an upstanding business that provides an honest, trustworthy, and transparent service to our customers. 

We saw a near-immediate change for the better in our energy bills. We've used them as our seasonal HVAC company ever since. This week they installed a new a/c unit, furnace, and two programmable thermostats in our house, fixing some not-up-to-code stuff they found along the way and generally just making everything work so much better. Their employees are also always on time, friendly and funny, and give good, honest advice about your system. We highly, highly recommend them!
