FAQs
How do I know it’s time to replace my HVAC unit instead of repairing it?
Several warning signs point toward replacement: (1) Your system is 12–15 years old or older; (2) Energy bills keep rising even after routine service; (3) You need major repairs that cost more than 30–40 % of the price of a new unit; (4) Uneven temperatures or excessive humidity persist; and (5) The unit still uses R-22 refrigerant, which is being phased out. During a free in-home evaluation our Dunlap technicians measure operating efficiency, inspect critical parts, and calculate life-cycle cost so you can make an informed decision.
What does a complete HVAC replacement typically cost in Dunlap and what affects the price?
In our area, a straightforward replacement usually ranges from $6,000 to $12,000, including equipment and labor. Price varies with: • System size (measured in tons or BTUs) required for your home’s square footage and insulation; • Efficiency rating (SEER2 for cooling, AFUE for heating); • Whether ductwork needs modification; • Choice of single-stage, two-stage, or variable-speed technology; • Added options such as smart thermostats, air purification, or zoning; and • Available rebates or tax credits. We provide a written, line-item quote and review financing options with 0 % interest plans for qualified homeowners.
How long will the replacement take and will I be without heating or cooling?
Most residential change-outs take one full day: roughly 4–6 hours to remove the old equipment, set the new condenser and air handler/furnace, connect electrical and refrigerant lines, and start up the system. If ductwork or electrical upgrades are needed, the job may extend to a second day. We schedule during mild weather whenever possible and can provide temporary heaters or portable AC units at no charge if extreme temperatures are expected.
Will a new high-efficiency system really lower my utility bills?
Yes. Modern equipment can be 30–50 % more efficient than systems installed 12–15 years ago. For example, replacing a 10 SEER air conditioner with a 16 SEER2 model can save $300–$500 per year on electricity for an average 2,000 sq ft home in Dunlap’s climate. Variable-speed compressors, ECM blower motors, and smart thermostats further reduce energy use by matching capacity to real-time demand. We calculate projected savings with ACCA Manual J and local utility rates so you see an accurate payback period before committing.
Do I need permits or inspections for HVAC replacement in Dunlap?
Yes. Sequatchie County and the City of Dunlap require a mechanical permit for any equipment change-out that involves refrigerant or gas lines. After installation, a county inspector verifies that the unit is sized correctly, pressure-tested, and vented safely. Our licensed installers handle all paperwork, schedule the inspection, and supply you with the signed approval for your records—no extra trips to city hall are necessary.
What kind of warranty and post-installation support do you provide?
We register every system with the manufacturer for a 10-year parts warranty and include a 1-year labor warranty at no additional cost. Extended labor coverage up to 10 years is available. To protect your investment, we offer a Comfort Club maintenance plan that provides two precision tune-ups per year, priority scheduling, and 15 % off any future repairs. Should you have questions or concerns, our live, locally staffed phone line is answered 24/7.
