FAQs
When should I consider replacing my HVAC unit in Kingsport?
Most systems last 12–15 years. If yours is approaching that age, needs frequent repairs, struggles to keep temperatures even, or causes unusually high energy bills, replacement is usually more economical than another major repair. Units that still use phased-out R-22 refrigerant are also prime candidates, because parts and refrigerant are expensive and scarce. Certified HVAC Pros offers free, no-obligation in-home evaluations so you know for sure whether a repair or a replacement makes the most sense.
How much does a new HVAC system cost in the Kingsport area?
A complete residential replacement—including equipment, labor, basic controls, and removal of the old unit—typically falls between $4,500 and $10,000. Costs vary with home size, system capacity, SEER2 efficiency rating, and any needed duct, electrical, or drain upgrades. After a detailed load calculation and onsite inspection, we provide a firm, written quote with no hidden fees. We also offer flexible financing, extended warranties, and seasonal promotions to make upgrading more affordable.
What size HVAC system does my Kingsport home need?
Proper sizing is critical for comfort, efficiency, and equipment life. We perform an ACCA Manual J load calculation that factors in square footage, insulation levels, window orientation, air leakage, and local climate data. The result tells us the exact cooling tons and heating BTUs required. Oversized units short-cycle and waste energy; undersized units run constantly and still leave hot or cold spots. Our NATE-certified technicians review the load report with you and recommend models that match your home’s requirements and budget.
How long will the replacement take and what should I expect on installation day?
Most straight change-outs (replacing the outdoor condenser, indoor coil/furnace, and thermostat) are completed in one full workday. If ductwork repairs, new line sets, or indoor air-quality upgrades are needed, plan on 1–2 additional days. We pull any required city or county permits in advance, protect your floors with drop cloths, remove and responsibly recycle the old equipment, pressure-test and evacuate the new refrigerant circuit, and perform a complete start-up checklist. Before we leave, we show you how to use the thermostat and register your factory warranty.
Are there any rebates or tax credits available for HVAC replacements in Kingsport?
Yes. Homeowners upgrading to high-efficiency heat pumps or air conditioners can currently claim up to $2,000 in federal tax credits under the Inflation Reduction Act. Tennessee Valley Authority’s EnergyRight program may offer rebates for qualifying heat pumps, and Kingsport Power often provides bill credits for ENERGY STAR® systems. Because incentives change frequently, we verify current programs, complete the paperwork, and supply the model and AHRI certification numbers you need to maximize your savings.
