FAQs
When should I consider replacing my HVAC unit instead of repairing it?
Most systems in Cosby last 12–15 years with proper maintenance. You should consider replacement when the unit is 10 years or older, requires frequent service calls, or when a single repair will cost more than 40 % of the price of a new system. Rising utility bills, uneven temperatures, excessive noise, or the use of the phased-out R-22 refrigerant are also strong indicators that replacement is the smarter long-term investment.
What factors influence the cost of a new HVAC system in Cosby?
Price is driven by several variables: • System type and efficiency rating (SEER2 for air conditioners, AFUE for furnaces, HSPF for heat pumps). • Heating and cooling capacity required for your home’s square footage, insulation level, and number of windows. • Whether you choose single-stage, two-stage, or variable-speed technology. • Ductwork condition—leaks or undersized ducts may need to be repaired or replaced. • Optional accessories such as smart thermostats, air purifiers, or zoning controls. • Local permitting fees and any electrical or gas line upgrades. We provide no-obligation, in-home estimates so you know the exact cost before work begins.
How long does an HVAC unit replacement take from start to finish?
For most residential projects, the physical removal of the old system and installation of the new one can be completed in 6–10 hours. If duct modifications, electrical upgrades, or a new concrete pad are required, the job may extend into a second day. Before installation we perform a load calculation, pull necessary Cosby or Cocke County permits, and schedule the inspection. All paperwork and cleanup are handled by our crew so you have minimal disruption.
Are there energy rebates or incentives available for new HVAC installations in Cosby?
Yes. TVA’s EnergyRight program frequently offers rebates for high-efficiency heat pumps and dual-fuel systems. Federal tax credits of up to $2,000 are available through 2032 for qualifying ENERGY STAR certified equipment. Local utilities such as Newport Utilities may provide bill credits for smart thermostats. We stay current on all rebate programs and will file the paperwork on your behalf to ensure you receive every dollar of available savings.
What size HVAC system do I need for my home?
Proper sizing is crucial. Oversized equipment short-cycles, wastes energy, and fails to control humidity; undersized units run constantly and wear out quickly. We use ACCA Manual J load calculations, taking into account square footage, insulation R-values, window orientation, ceiling height, and even household occupancy. The result is a right-sized system—usually 1 ton of cooling per 600–800 sq ft in our climate, but exact requirements can vary by 20 % or more depending on your home’s specifics.
How can I maintain my new HVAC unit to maximize its lifespan and efficiency?
1. Change or clean air filters every 1–3 months. 2. Keep the outdoor condenser clear of leaves, grass clippings, and debris. 3. Schedule professional tune-ups each spring and fall; they include coil cleaning, refrigerant checks, and safety tests. 4. Use a programmable or smart thermostat to avoid extreme temperature swings. 5. Seal and insulate ductwork to reduce energy loss. 6. Register your new equipment with the manufacturer within 60 days to secure the 10-year parts warranty. Following these steps can extend system life well beyond its average expectancy and save 10 %–15 % on annual energy costs.
