FAQs
How does your transparent pricing model work for HVAC unit replacements in Karns?
We publish our complete price schedule online and show you exactly how each line item on your quote is calculated—equipment cost, labor, permits, disposal, and taxes. During the in-home assessment our comfort advisor measures your home, reviews ductwork, and notes any code upgrades that may be required. You receive a printed or emailed quote before we leave, and the price you sign for is the price you pay. There are no hidden fees or “change-order” surprises once installation begins.
What factors influence the final cost of replacing my heating and air system?
Price is determined by five main variables: (1) system capacity (measured in BTUs or tons) matched to your home’s square footage and insulation level; (2) efficiency rating (SEER2 for cooling, AFUE for heating); (3) choice of technology—single-stage, two-stage, or variable speed; (4) any ductwork modifications or code upgrades required; and (5) optional accessories such as smart thermostats, air cleaners, or humidity control. Our detailed quote breaks each of these out so you can see exactly where your dollars go.
How quickly can you replace my HVAC unit after I approve the quote?
Most standard residential replacements in Karns can be scheduled within 1–3 business days once you accept the proposal. If we need to special-order equipment or address extensive duct repairs, the timetable may extend to 5–7 days. Emergencies receive priority scheduling, and we keep popular system sizes in local inventory so you’re not left without heating or cooling for long.
Are there financing or rebate options available for Karns homeowners?
Yes. We partner with several local and national lenders to offer 0% APR financing for up to 18 months or low-interest plans up to 10 years. TVA’s EnergyRight program and manufacturer incentives can provide rebates of $200–$1,000 on qualifying high-efficiency equipment. We handle all paperwork and will apply any rebates as an instant credit on your invoice so you don’t wait for a mailed check.
How do I know what size HVAC system my home needs?
Our technician performs a Manual J load calculation, the industry’s gold standard for sizing. It accounts for square footage, window orientation, insulation, occupancy, and local Karns climate data. Oversized units cycle off too quickly, leaving humidity and temperature swings, while undersized units run constantly and raise energy bills. The load calculation ensures the system we recommend is precisely matched for peak comfort and efficiency.
What warranties and post-installation support do you provide?
Every new system comes with a 10-year manufacturer parts warranty and our own 2-year labor warranty at no extra charge. Register your equipment within 60 days and the parts warranty extends to 12 years on select models. You’ll also receive one year of complimentary maintenance (spring AC tune-up and fall furnace inspection). Our 24/7 service line means you get priority scheduling and no overtime rates if any covered issue arises.
