FAQs
How can I tell that it’s time to replace my HVAC system in Cosby?
Most heat pumps and air-conditioning systems last 10–15 years. You may need a replacement sooner if you notice frequent breakdowns, rooms that never reach the set temperature, loud or unusual noises, musty odors, or energy bills that keep creeping up even after routine maintenance. A licensed technician can run a load calculation and efficiency test to confirm whether a new unit will solve these issues and reduce operating costs.
What is the typical cost to replace a residential HVAC unit in Cosby, TN?
For an average 1,500–2,000 sq-ft home in Cosby, total replacement costs generally fall between $6,000 and $12,000. The final price depends on the size (tonnage) of the equipment, SEER2 efficiency rating, choice of heat pump vs. furnace/AC split system, ductwork modifications, thermostat upgrades, and any indoor-air-quality add-ons such as UV lights or high-MERV filtration. We provide free in-home estimates so you can see a line-item breakdown before approving the work.
How long will the HVAC replacement process take?
Most standard change-outs can be completed in one working day, including removal of the old equipment, installation of the new indoor and outdoor units, refrigerant charging, and start-up testing. If you need major duct revisions, a new line set, or electrical panel upgrades, the project may extend to two days. We coordinate permitting and inspections in advance to keep downtime to a minimum, and we always leave one technician on site until the system is running and your home is comfortable.
Are there any rebates or tax incentives available for upgrading my HVAC system in Cosby?
Yes. Cosby homeowners may qualify for TVA EnergyRight® rebates on qualifying high-efficiency heat pumps (up to $400) and smart thermostats (up to $50). Federal tax credits under the Inflation Reduction Act offer 30% of equipment and labor costs—up to $2,000—for systems rated ≥15.2 SEER2 (heat pumps) or ≥16 SEER2 (central AC). Income-based rebates from the forthcoming HOMES program could reduce costs even more. We handle the paperwork and provide AHRI certificates so you receive every dollar you’re entitled to.
Will I need a permit or inspection for an HVAC replacement in Cosby?
Yes. Sevier County requires a mechanical permit for any equipment replacement that involves refrigerant lines, electrical wiring, or duct alterations. Our team pulls the permit on your behalf, schedules the county inspection, and ensures the new installation meets the International Residential Code (IRC), local amendments, and manufacturer specifications. You’ll receive the signed inspection card and warranty registration documents for your records.
Do you offer financing or other payment options for HVAC replacements?
Absolutely. We partner with Wells Fargo, Synchrony, and TVA’s EnergyRight® Residential Loan Program to provide financing plans ranging from 6- to 120-month terms. Options include 0% APR for up to 18 months or low monthly payments starting under $100, subject to credit approval. We also accept all major credit cards and provide discounts for veterans, first responders, and seniors in Cosby. Our comfort advisor will review every option so you can choose the plan that best fits your budget.
