FAQs

How do I know it’s time to replace my HVAC system instead of repairing it?

Most systems last 12–15 years; after that, efficiency drops and repair costs climb. Warning signs include frequent breakdowns, uneven temperatures, rising utility bills, loud operation, or the use of R-22 (Freon) refrigerant, which is no longer produced. Our certified technicians can perform a cost-benefit analysis: if a repair exceeds 30–40 % of the price of a new, high-efficiency unit, replacement is usually the smarter, long-term choice.

What size HVAC unit do I need for my Dunlap home?

Proper sizing depends on square footage, insulation, window types, duct layout, and even local humidity levels in Dunlap’s valley climate. During a free in-home consultation we perform a Manual J load calculation to determine the exact British Thermal Units (BTUs) required. Correct sizing prevents short-cycling, lowers energy bills, and maximizes comfort year-round.

How long does a typical HVAC replacement take?

Most residential change-outs can be completed in one day. We start with system evacuation and safe removal of the old unit, inspect or modify ductwork, set the new indoor and outdoor components, run refrigerant lines, pressure-test and vacuum-seal the system, then perform a full start-up and thermostat calibration. Larger homes, zoning upgrades, or significant duct revisions can extend the job to two days, but we’ll let you know the exact timeline before work begins.

Are your technicians certified and insured?

Yes. Every installer holds EPA Section 608 certification for refrigerant handling and NATE (North American Technician Excellence) credentials for HVAC proficiency. We also maintain Tennessee mechanical contractor licensing, workers’ compensation, and $2 million in general liability insurance. Copies of certificates are available upon request for your peace of mind.

What energy-efficiency options or rebates are available for new HVAC installations in Dunlap?

We offer ENERGY STAR®-rated heat pumps and air conditioners with SEER2 ratings up to 20+. Sequatchie Valley Electric Cooperative members may qualify for rebates of $150–$400 on high-efficiency heat pumps. Federal tax credits under the Inflation Reduction Act provide up to $2,000 for qualifying heat pump installations. Our office handles all paperwork and will apply rebates as instant discounts whenever possible.

Do you provide financing or maintenance plans for new HVAC systems?

Absolutely. We partner with trusted lenders to offer 0 % APR financing for 12 months and low-interest plans up to 120 months with no pre-payment penalties. After installation you can enroll in our Comfort Club, which includes two precision tune-ups per year, priority scheduling, no overtime fees, and a 10 % parts discount—helping your new system stay efficient and under warranty.
