I have been using Executive Heating & Air for five years and the reason I have stayed with them is that they do not try to upsell products we don't need. Before we began using Executive Heating & Air, we had a company come out that wanted to replace equipment. We got a second opinion from Executive Heating & Air and they said we didn't need new equipment. They have been maintaining our HVAC system since then and it is still working perfectly. I recently called them out to check our smoke alarm/carbon monoxide detectors because I was getting an alert. It was a problem in the system; they did a repair and we have had no more problems. I highly recommend using them. They are professional, helpful, and knowledgeable. They are always on time and wear shoe covers to protect the floors. If you want an honest, high-quality company to do business with; you couldn't do better than Executive Heating & Air.
