FAQs
What are the most common signs that my HVAC system should be replaced rather than repaired?
In Tazewell, we typically recommend replacement when your heat pump or furnace/AC system is 12–15 years old, needs frequent or costly repairs (more than 25 % of the price of a new unit), shows a sudden spike in monthly utility bills, delivers uneven temperatures or excessive humidity, or still uses phased-out R-22 refrigerant. Any one of these issues can indicate that the core components are close to failure and that investing in a new high-efficiency system will be more economical in the long run.
How can a high-efficiency HVAC replacement lower my energy bills in Tazewell?
High-efficiency units carry higher SEER2 (cooling) and HSPF2 (heating) ratings and often feature variable-speed compressors, ECM blower motors, and smart thermostats. In Tazewell’s mixed, humid climate, these technologies allow the system to run at partial capacity most of the time, cutting energy consumption by 20 – 40 % compared with a 10- to 15-year-old unit. They remove more moisture during the long cooling season and maintain steadier temperatures in winter, which means less cycling and lower utility costs year-round.
What size HVAC system is right for my Tazewell home?
Proper sizing is critical. We perform a Manual J load calculation that factors in square footage, insulation levels, window type and orientation, air leakage, number of occupants, and Tazewell’s Climate Zone 4A weather data. A unit that’s too large will short-cycle and waste energy; one that’s too small will struggle on peak hot or cold days. After the load calculation, we present several properly sized, high-efficiency models so you can compare comfort features and operating costs.
Are there rebates or tax credits available in Tazewell for high-efficiency HVAC replacements?
Yes. The current federal 25C tax credit covers up to 30 % of the installed cost of qualifying ENERGY STAR heat pumps and central ACs, with a cap of $2,000 per year. Many Tennessee Valley Authority (TVA) EnergyRight programs and Appalachian Power rebates also provide $150–$600 per system for high-efficiency equipment. We handle the paperwork, confirm eligibility, and apply any manufacturer incentives to reduce your out-of-pocket expense.
How long does an HVAC unit replacement take, and will I be without heating or cooling?
Most standard change-outs in Tazewell are completed in a single day—about 4–8 hours for removal, new equipment placement, line-set flushing, electrical connections, refrigerant charging, and a start-up test. If you need duct repairs or indoor air-quality add-ons, the job may extend into a second day. We schedule installations so you’re rarely without heating or cooling for more than a few hours and always leave at least one room comfortable during extreme weather.
What maintenance does my new high-efficiency HVAC system require to stay efficient?
1) Change or clean air filters every 30–90 days. 2) Keep the outdoor condenser/heat-pump coil clear of leaves and debris. 3) Schedule professional tune-ups each spring and fall to check refrigerant pressure, clean coils, tighten electrical connections, lubricate moving parts, and calibrate the thermostat. 4) Have the condensate drain inspected yearly to prevent clogs. 5) Record all service visits to maintain the manufacturer’s 10- or 12-year parts warranty. These simple steps protect your investment and keep efficiency and comfort levels high.
