I recently had a new furnace installed by House Smart Home Improvements. The two brothers who did the installation work were very professional and competent people! All the people I dealt with were very nice, and very accommodating. There was a supply-chain problem getting the furnace I originally ordered. When fall began to approach, the company upgraded me to another furnace that they had in stock, at no charge to me! That was very nice of them, and I was very impressed! I am a happy customer!
