FAQs
How do I know it’s time to replace my HVAC unit in Karns rather than repair it?
In East Tennessee’s humid subtropical climate, systems work harder year-round. If your heat pump or air conditioner is 10–15 years old, needs frequent repairs, uses R-22 refrigerant, or causes utility bills to spike despite regular maintenance, replacement is usually the more cost-effective option. A new high-efficiency unit can cut cooling costs 20–40 %, provide better dehumidification, and qualify for manufacturer or utility rebates.
What size HVAC system is best for my home in Karns?
Proper sizing is critical; an oversized system short-cycles and wastes energy, while an undersized unit can’t keep up with summer humidity. We perform a Manual J load calculation that factors in square footage, insulation levels, window orientation, local weather data, and even household occupancy. The result ensures the new system delivers consistent 72 °F comfort, balanced humidity, and maximum efficiency.
Which efficiency rating (SEER2/HSPF2) should I look for in East Tennessee?
Starting in 2023, the minimum efficiency for the Southeast region is 14.3 SEER2 for air conditioners and 7.5 HSPF2 for heat pumps. We generally recommend 16–18 SEER2/8 HSPF2 models for Karns homeowners—they strike an excellent balance between upfront cost and lifetime energy savings. If you plan to stay in your home 10+ years or want to maximize TVA incentives, 20+ SEER2 variable-speed systems provide the greatest savings and comfort.
What is the typical cost of an HVAC replacement in the Karns area?
Installed pricing varies with system size, efficiency level, ductwork upgrades, and add-ons like whole-home dehumidifiers. For a 1,800 sq ft home, expect $6,500–$9,500 for a standard 15 SEER2 heat-pump system and $10,000–$14,000 for a high-efficiency variable-speed unit. We offer free in-home estimates, transparent line-item quotes, and financing options with low monthly payments through TVA EnergyRight and local credit unions.
How long does it take to replace an HVAC system, and will I be without heating or cooling?
Most change-outs in Karns can be completed in a single day. Our crew removes the old equipment, modifies the duct connections if needed, installs the new indoor and outdoor units, evacuates and charges the refrigerant, and tests airflow and controls. Your home may be without conditioned air for 4–6 hours, but we schedule installations to minimize downtime and always leave the job site clean.
What warranties and maintenance are required after installation?
New systems come with a 10-year parts warranty and up to 10 years of compressor coverage when registered within 60 days. We include a one-year labor warranty and recommend enrolling in our Comfort Club, which provides semi-annual tune-ups, priority service, and keeps your manufacturer warranty valid. Regular maintenance—filter changes every 1–3 months, coil cleaning, and thermostat calibration—protects your investment and ensures peak efficiency in East Tennessee’s demanding weather.
