My furnace died just as Austin was heading towards a hard freeze. I got a very high quote from another company and started calling around for someone who could give me a second opinion on short notice. Everyone was booked. Smart Air was too, apparently, but given the circumstances Shane was willing to come by in the evening and take a look at my furnace.
Shane was very thorough, and seemed not at all bothered by the fact that I was hovering anxiously. He was happy to answer my questions and he explained exactly what he was seeing and what he thought the problem was.
The problem? Dust. Whoever owned my home before me had never used an air filter (!!) so my unit was excessively dusty. It had caused the circuit board to fail. Shane cleaned off the board and got the furnace working. It failed again two days later (Shane warned me it might, I was just trying to be cheap) and he was able to come out and replace the board that day.
Compared to the original quote I received from another company, Smart Air saved me a lot of money on parts. Their labor charges were reasonable.
As a property manager, I have dealt with a number of HVAC companies in town, and Smart Air was by far the most all-around positive experience I have had. They will be the first place I call if I ever have AC or furnace trouble in the future.
