FAQs
How do I know it’s time to replace my HVAC system instead of repairing it?
Most systems last 12–15 years in Johnson City’s mixed-climate conditions. If your unit is nearing that age, needs frequent repairs, uses R-22 refrigerant, or your energy bills keep rising even after tune-ups, replacement is usually more economical. Our technicians can run a cost-of-ownership comparison so you see whether a new high-efficiency unit will save more than a major repair.
What size and type of HVAC unit is best for homes in Johnson City?
Proper sizing is critical; too large short-cycles and wastes energy, too small struggles in our humid summers and cold winters. We perform a Manual J load calculation that factors in square footage, insulation, window orientation, and local design temperatures (92 °F summer / 19 °F winter). Depending on those results we may recommend a 14–18 SEER2 heat pump, dual-fuel system, or high-efficiency gas furnace paired with an AC. We present at least two right-sized options so you can balance upfront cost and long-term savings.
How long does an HVAC replacement take, and will I be without heating or cooling?
A straightforward replacement in the same location typically takes one full working day (6–8 hours). More complex jobs—such as duct modifications, line-set rerouting, or upgrading the electrical service—may add another day. We schedule during mild weather when possible, set portable heaters or coolers for vulnerable customers, and always test and commission the new unit before we leave so you have comfort the same day.
Are there energy rebates, tax credits, or financing options available in Johnson City?
Yes. The federal Inflation Reduction Act now offers up to a $2,000 tax credit for qualifying heat pumps and up to $600 for advanced furnaces or air conditioners. BrightRidge and TVA often add $150–$400 rebates for ENERGY STAR units, and Tennessee’s TPMA loan program offers low-interest financing spread over your utility bill. Our office staff handles the paperwork and deducts instant rebates from your invoice whenever possible.
What should I expect when your seasoned technicians arrive for the replacement?
We start with a brief walkthrough to cover safety and answer questions. Floors and furniture are protected with drop cloths, and the old equipment is evacuated, disconnected, and hauled away for eco-friendly recycling. The new condenser, air handler/furnace, and thermostat are installed, refrigerant lines and electrical are pressure-tested, and ducts are sealed if needed. Before we leave, we perform a full performance test, register your warranty, and show you how to operate the new thermostat.
How can I maintain my new HVAC system to maximize lifespan and efficiency?
Change or wash air filters every 30–60 days, keep the outdoor condenser free of leaves and grass clippings, and schedule professional maintenance twice a year—once before cooling season and once before heating. Our Comfort Club includes these tune-ups, priority service, and a 15 % repair discount. Regular maintenance preserves your manufacturer warranty and can cut energy consumption by 10–15 % annually.
