FAQs
How do I know if my HVAC unit needs to be replaced rather than repaired?
In Blountvilleâs four-season climate, an HVAC system typically lasts 12â15 years. Consider replacement when your unit is nearing that age, requires frequent or increasingly expensive repairs, struggles to keep a steady temperature, causes utility bills to rise sharply, or uses R-22 refrigerant (no longer produced). Our certified technicians can perform a free in-home assessment to compare the long-term cost of repair versus replacement.
What is involved in the HVAC replacement process and how long will my home be without heating or cooling?
A standard change-out takes one full day. We start with a Manual J load calculation to size the equipment, inspect ductwork, discuss comfort goals, and secure permits with Sullivan County. On installation day we safely remove the old equipment, set the new indoor and outdoor units, connect refrigerant and electrical lines, pressure-test and evacuate the system, charge it to factory specs, and run a full performance check. Your home is typically without heating or cooling for only 3â6 hours during the swap.
Which HVAC brands and systems do your certified technicians recommend for Blountvilleâs climate?
We are factory-authorized dealers for Trane, Carrier, and Rheemâbrands known for reliability in humid summers and chilly Appalachian winters. For most homes we suggest: (1) 14â16 SEER2 single-stage heat pumps for budget-minded owners, (2) 17â19 SEER2 two-stage or variable-speed heat pumps or gas furnaces/AC combos for superior comfort and efficiency, and (3) geothermal or ductless mini-splits for homes without existing ductwork or those seeking the lowest operating costs.
How much does a full HVAC replacement cost in Blountville and what factors influence the price?
A straight system replacement (equipment only) usually ranges from $5,500 to $12,000. Costs vary with equipment efficiency (SEER2/HSPF rating), capacity (measured in tons or BTUs), indoor coil type, thermostat technology, duct modifications, and any code-required upgrades such as surge protection or condensate safety switches. After an onsite evaluation we provide a line-item proposal so you can see exactly where every dollar goes.
Do you offer financing, rebates, or tax incentives for new high-efficiency HVAC systems?
Yes. We partner with local and national lenders to offer 0% APR plans for up to 18 months or low-interest terms up to 120 months, subject to credit approval. TVAâs EnergyRight program offers rebates on qualifying heat pumps, and federal tax credits of up to 30% (capped at $2,000) are available through 2032 for ENERGY STARÂŽ high-efficiency systems. We handle all paperwork so you receive every possible savings.
What warranties and maintenance plans come with my new HVAC unit?
Most of our systems carry a 10-year manufacturer parts warranty and a one-year labor warranty that we extend to 10 years with an annual maintenance agreement. Our Comfort Club plan includes two seasonal tune-ups, priority service, and 15% off future repairs. Routine maintenance keeps your warranty valid and maximizes system life and efficiency.
