SmartHouse: SmartServiceman! I contacted SmartHouse about servicing my AC unit only to learn it would be a week before they had an opening on the calendar for me. The next day, I received a call... letting me know that due to a cancellation, they could have someone at my home that afternoon. Marcus called me when he was 15 minutes out, and when he arrived, he immediately got to work. He explained a few things to me, made some helpful suggestions, made sure I had a clean filter, he even sprayed a wasp nest lurking around the window next to my front door, and he witnessed my Rottweiler repeatedly opening the door trying to see why we were standing outside of his garage. Marcus did what he needed to do to get the job done, and was on his way within about 35 minutes; he was very professional, knowledgeable and personable. I appreciated how informative and polite Marcus was with me, and I will personally request him as my serviceman each time I need to contact SmartHouse.Thank You, Jennifer!read more

We originally found SmartHouse several years back when we were looking for a company to do an energy audit of our 120-year-old home. Because of the audit they did, we hired them to do the recommended... work, and 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!read more

I was very satisfied with the installation of a new furnace performed by Smart House. The installation was done in the attic, and included some tricky maneuvers to first remove the old unit. I... witnessed the crews' problem solving and their ease and confidence and use of additional manpower called in, to be successful with it.The installation of the new furnace was done efficiently, communication with me on their progress was consistent, and the prep work and clean up involved with keeping my main floor hardwoods and carpeting protected up three flights of stairs was appreciated!!Overall, the crew did an excellent job. They had a great work ethic, were on time for the appointment, and were professional and yet pleasant in their interactions with me. I would hire SmartHouse again in an instant.(I should add that the company owner actually came to my house months before the installation and must have spent 45 minutes helping me to understand my options about what seemed to be my failing furnace. This was free of charge but definitely aided me in making the decision to use their services.)read more
