FAQs
When should I replace my existing HVAC unit instead of repairing it?
Most systems in Sewanee reach the end of their reliable life at 12–15 years, especially because our humid summers and chilly mountain winters make the equipment work harder. If your unit needs frequent repairs, uses R-22 refrigerant, struggles to maintain set temperatures, or your utility bills have climbed more than 20 % year-over-year, replacement is usually the most cost-effective choice. A new high-efficiency heat pump or gas furnace/AC combo can cut energy costs up to 40 %, quickly offsetting the investment.
What does a complete HVAC replacement cost in Sewanee, and what influences the price?
For a typical 1,800–2,400 sq ft home, turnkey replacement (equipment, installation, permits, and haul-away) runs $6,500–$12,000. Costs vary with capacity (measured in tons or BTUs), SEER2/HSPF efficiency ratings, ductwork modifications, thermostat upgrades, and whether you choose standard, mid-range, or premium brands. HEP Heating & Air provides no-surprise, written quotes after a free in-home load calculation that pinpoints the exact size and features your home needs.
How do I know what size HVAC system my Sewanee home requires?
Proper sizing is critical in our mountain climate, where temperature swings and humidity are common. We perform a Manual J load calculation that measures square footage, insulation levels, window types, orientation, duct condition, and air infiltration. This scientific approach prevents the common "bigger is better" mistake that short-cycles equipment, wastes energy, and reduces comfort. You’ll receive a detailed report showing the tonnage or BTU rating that will keep every room comfortable year-round.
How long will the replacement take and will I be without heating or cooling?
Most standard change-outs are completed in one day. Complex jobs that involve duct revisions or zoning can take two to three days. Our team arrives with all equipment pre-staged, protects your floors, and removes the old system for recycling. We schedule work when outdoor conditions are manageable and keep at least one zone running whenever feasible, so downtime is usually only a few hours.
Are there energy rebates or tax credits available for a new HVAC system in Tennessee?
Yes. TVA’s EnergyRight program currently offers rebates of $150–$400 for qualifying high-efficiency heat pumps installed by a Quality Contractor Network member such as HEP Heating & Air. Federal tax credits under the Inflation Reduction Act provide up to $2,000 for heat pumps meeting CEE Tier II efficiency, plus up to $600 for an efficient air conditioner or gas furnace. We’ll handle the paperwork and supply AHRI certificates to ensure you receive every incentive you’re entitled to.
What warranties and after-installation support does HEP Heating & Air include?
All new systems come with a 10-year manufacturer parts warranty and our 1-year labor warranty, which you can extend to 10 years with an optional maintenance agreement. We register your equipment, provide the first-year tune-up free, and offer 24/7 emergency service with priority scheduling for our replacement customers. If any workmanship issue arises, we repair it at no cost during the warranty period—guaranteed.
