We had our HVAC equipment replaced about 6 years ago. When we bought the house, we inherited the HVAC equipment. It was decent enough HVAC equipment and had life left in it. So we had the seller knock a bit off the price in order for us to keep the HVAC unit. And it did fine for about 5 years which is what we had hoped for. But once the heating and cooling costs spiked, we knew that it was time to replace the HVAC unit. So we worked with the HVAC company who did the HVAC maintenance and it couldn’t have been easier. The HVAC contractor actually came to our house to discus our options and inspect the ductwork. We were able to see all the different options when it came to new residential HVAC. My wife really pushed for going all in on the new HVAC technology but I was more interested in keeping the costs down. We compromised with getting the best HVAC technology on the equipment with a SEER rating that was super efficient. But we didn’t go with the smart thermostat that was new at that point. So six years later, I finally had the HVAC company install a smart thermostat. I had gone to the trouble of learning how to program the old thermostat so I thought I was getting all the HVAC savings possible. Well, after just one month of HVAC cooling, the smart thermostat saved an additional 15 percent over the savings that I’d previously seen. We’re sure glad to have the smart thermostat from a savings perspective as well as its convenience factor.
