Your AC quits when it’s 90 degrees, or your furnace stops on the coldest week of the year, and suddenly you’re not shopping for “a company” you’re searching for someone you can trust to show up, communicate clearly, and respect your home. We sat down with Nick and Jeremiah Harritt, brothers and business partners behind HRS Heating and Cooling, to talk about what dependable local HVAC service should feel like in Morgan County and Martinsville. We get specific about the stuff homeowners hear all the time but rarely get explained: what EPA certification actually means for refrigerant work, why being licensed, bonded, and insured protects you, and how modern heating and cooling systems have changed with new refrigerants, added sensors, and smarter controls. Nick and Jeremiah also share how they keep their technicians sharp through ongoing HVAC training, including supplier sessions and even a factory tour that shows how today’s air conditioners and furnaces are built and tested. Indoor air quality comes up a lot too, and we dig into what homeowners are asking for now: whole-home humidifiers, UV lights, and better filtration to help with comfort and cleaner air. Then we shift to real-world decision making: the warning signs that suggest it’s time to repair versus replace, why preventative maintenance plans matter, and how financing options can turn a major HVAC replacement into a manageable monthly payment. We also break down system types like single-stage, two-stage, variable speed, and modulating equipment, plus a candid warning about costly DIY mistakes on newer control boards. If you value responsive local service and want to make smarter choices about HVAC repair, AC installation, furnace replacement, and indoor air quality, hit play.
