Based on Yelp reviews, I called Residential Heating and AC to do an inspection of our ducts, as well as check operation of our furnace. Jim S. responded to our call and was right on time! He is a nice, efficient, knowledgeable guy to work with. He detected that some wires had not been correctly connected when the unit was installed by another company. Within 1.5 hours, the unit was cleaned, inspected and repaired. I was expecting a bill big enough to fund a war – as well as a negative verdict. I was pleasantly surprised by the reasonable cost and outcome and will use them as our vendor of choice in the future.
