FAQs

What types of heating and air-conditioning systems can you install in Sevierville homes?

We install a full range of residential and light-commercial HVAC equipment, including high-efficiency split heat pumps, conventional gas furnaces with central air conditioners, dual-fuel hybrid systems, ductless mini-splits, geothermal heat pumps, packaged rooftop units, and indoor air-quality accessories such as dehumidifiers and ERVs. During your free in-home consultation we evaluate your home’s size, insulation, and ductwork to recommend the system that balances comfort, efficiency, and upfront cost.

How long does a typical HVAC system installation take?

Most standard replacements—removing an old furnace and A/C and installing new matched equipment—are completed in one full working day (6-10 hours). More complex jobs, such as adding new duct runs, installing a multi-zone ductless system, or drilling geothermal loops, can take 2–4 days. We give you a detailed timeline before work begins and strive to minimize downtime so you’re never without heating or cooling overnight.

Do I need permits or inspections for a new HVAC installation in Sevierville?

Yes. Sevierville and Sevier County require mechanical permits for new HVAC installations and replacements that involve gas, refrigerant, electrical, or structural changes. Our company handles the entire permitting process, schedules required inspections with the city or county building department, and provides you with copies of all documentation for your records and potential home-sale disclosures.

How much does a new heating and cooling system cost?

Pricing varies with system size (tonnage/Btus), efficiency rating (SEER2, HSPF2, AFUE), and any duct or electrical upgrades. In Sevierville, a basic 2-ton 14.3-SEER2 heat-pump system starts around $6,500 installed, while a high-efficiency 18-SEER2 variable-speed system can range from $9,000 to $14,000. We provide written, line-item proposals and several good-better-best options so you can choose a solution that fits your budget and comfort goals. Financing with low monthly payments is available for qualified homeowners.

What warranties or guarantees do you offer on new installations?

All equipment comes with a manufacturer’s factory warranty—typically 10 years on parts for registered residential systems. Our company adds a one-year labor warranty and a Lifetime Workmanship Guarantee, which means any installation-related issue (duct sealing, refrigerant line integrity, condensate drainage, etc.) is corrected at no cost to you. Extended labor warranties up to 10 years are available. We also provide one complimentary preventive-maintenance visit after the first heating and cooling seasons.

How can I prepare my home for installation day?

1) Clear a 3-4-foot path from the driveway to the mechanical area and outdoor condenser pad. 2) Remove fragile items from walls and shelves near the work zone, as vibration can cause them to fall. 3) Secure pets in a separate room or kennel. 4) Plan for the system to be off during installation; in summer, close blinds to keep rooms cooler, and in winter, use supplemental space heaters if needed. 5) Make available a standard 110-V outlet for our power tools. Our crew will protect floors with drop cloths, wear shoe covers, and clean up thoroughly before leaving.
