FAQs

How can I tell whether it’s time to replace my HVAC system instead of repairing it?

In Mountain City’s four-season climate, systems work hard year-round. We generally recommend considering replacement when: • Your heat pump, AC, or furnace is 12–15 years old. • Energy bills have crept up even after routine maintenance. • You’re facing a repair that costs more than 30–40 % of the price of a new system. • Comfort problems—uneven temperatures, excessive humidity, or noise—persist. • Your current equipment uses R-22 refrigerant, which is no longer produced. A no-cost load calculation and inspection by our Comfort Specialist will confirm whether repair or replacement is the better value.

What size HVAC unit do I need for my Mountain City home?

Proper sizing depends on your home’s square footage, insulation levels, window orientation, and even elevation (Mountain City sits about 2,400 ft above sea level, which affects air density). We perform a Manual J load calculation that factors in: • Living area and ceiling height • Number of occupants and appliances • Local design temperatures (92 °F summer, 15 °F winter) • Air-leakage test results The result is a heating and cooling capacity recommendation, expressed in BTUs and tons. Correct sizing prevents short-cycling, maximizes efficiency, and lengthens equipment life.

How long will HVAC replacement take and will I be without heating or cooling during the process?

Most residential change-outs take one full working day. We coordinate permits with Johnson County, arrive with all equipment pre-staged, and dispose of your old unit responsibly. Power or gas is typically off for 4–6 hours during switchover; we schedule around extreme weather and can provide space heaters or portable ACs if needed. Duct modifications or indoor-air-quality add-ons (humidifiers, UV lights) can add half a day, but we’ll let you know in advance.

Are there energy-efficient options that qualify for rebates or tax incentives in Mountain City?

Yes. High-efficiency heat pumps (≥15.2 SEER2 / 7.8 HSPF2) and furnaces (≥97 % AFUE) often qualify for: • Federal Energy-Efficient Home Improvement Tax Credits—up to $2,000 for heat pumps, $600 for furnaces. • Tennessee Valley Authority (TVA) EnergyRight rebates—currently $300–$400 for qualifying heat pumps. • Local utility bill credits from Mountain Electric Co-op for smart thermostats. We handle all paperwork and provide AHRI certificates so you receive every available incentive.

How much does a complete HVAC replacement cost and what financing options do you offer?

For a typical 2- to 3-ton system in Mountain City, pricing averages: • Single-stage heat pump or AC/furnace split: $6,500–$8,500. • High-efficiency two-stage or variable-speed system: $9,000–$12,500. • Ductless mini-split (per zone): $3,800–$5,200. The quote includes equipment, labor, permits, disposal, and the first-year maintenance visit. We partner with Wells Fargo and Synchrony to offer 0 % APR plans for 18 months or low-interest terms up to 10 years. Veterans and seniors receive an additional 5 % discount.

What maintenance does a new HVAC system require to keep the warranty valid?

Manufacturers such as Trane, Carrier, and Rheem require: • Registration of the new unit within 60 days of installation. • Professional maintenance at least once a year for heat pumps (twice if you have separate furnace/AC). • Use of OEM replacement parts and approved refrigerants. Our Comfort Club fulfills these requirements with bi-annual tune-ups, filter changes, coil cleaning, and thermostat calibration. You receive documentation of each visit, which protects your 10- or 12-year parts and compressor warranty and helps maintain peak efficiency.
