FAQs
When should I consider replacing my gas furnace and central air conditioner in Rogersville?
Most gas furnaces and split-system air conditioners last 15–20 years in our Rogersville climate. You should think about replacement if your equipment is approaching that age, needs frequent repairs, creates hot/cold spots, or if utility bills keep climbing even after routine tune-ups. Newer systems offer 20–40 % higher efficiency (up to 98 % AFUE for furnaces and 16–20 SEER2 for A/Cs), so upgrading can quickly offset the cost through energy savings and fewer service calls.
How do I make sure the new HVAC units are the correct size for my home?
Proper sizing is critical. Our technicians perform a Manual J load calculation that measures square footage, insulation levels, window types, orientation, and local design temperatures for Rogersville (Zone 4, 93 °F summer / 14 °F winter). This data determines the exact BTU and tonnage required. Oversized systems short-cycle and waste energy; undersized systems run constantly and wear out early. We also look at ductwork capacity and airflow (CFM) to ensure the whole system is balanced before recommending equipment.
What does a full gas furnace and A/C replacement typically cost in Rogersville?
Pricing depends on home size, efficiency ratings, and any needed duct modifications, but most complete replacements run $7,000–$12,000 installed. High-end variable-speed or two-stage equipment can be $2,000–$3,000 more. We provide itemized proposals that break down equipment, labor, permits, and optional add-ons like air purifiers or smart thermostats. Up-front rebates, manufacturer promotions, and 0 % financing for 12–72 months help fit the project into your budget.
How long will the installation take, and will I be without heating or cooling?
A straight furnace-and-coil swap with a new outdoor condenser normally takes one full working day. If duct repairs, electrical upgrades, or line-set replacements are needed, plan on 1½–2 days. We schedule during mild weather whenever possible, bring temporary heaters or window A/C units if extreme temperatures are expected, and never leave you overnight without at least one form of conditioned air.
Are there energy-efficiency incentives or rebates available to Rogersville homeowners?
Yes. Qualifying ENERGY STAR gas furnaces (≥97 % AFUE) and high-efficiency air conditioners (≥16 SEER2) are eligible for up to a $600 federal tax credit each under the Inflation Reduction Act. Liberty Utilities and KUB (for parts of Hawkins County) sometimes offer $200–$500 bill credits for efficient electric A/C units. Tennessee Valley Authority customers may obtain low-interest Heat Pump loans if you choose a dual-fuel system. We complete the paperwork and provide AHRI certificates so you receive every available incentive.
What kind of warranty and post-installation support do you provide?
Most of our preferred manufacturers include a 10-year parts warranty and a limited lifetime heat-exchanger warranty on their gas furnaces when registered within 60 days of install. Our Rogersville HVAC team adds a 1-year labor warranty, with optional extended labor coverage up to 10 years. Annual maintenance plans start at $14.95 per month and include two precision tune-ups, filter changes, priority scheduling, and 15 % off future repairs—protecting your investment and keeping manufacturer warranties intact.
