FAQs
What are the most common signs that my HVAC unit in Sewanee needs to be replaced rather than repaired?
Frequent or costly breakdowns, rooms that are consistently too hot or too cold, energy bills that have risen sharply without a corresponding change in usage, loud or unusual operating noises, and equipment that is 12–15 years old are the biggest indicators that replacement is more economical than repair. A professional load calculation and inspection will confirm whether the unit is undersized, has a failing compressor, or uses the now-banned R-22 refrigerant—all factors that typically justify a full replacement in Sewanee’s variable climate.
How long does an HVAC unit replacement usually take from start to finish?
For most single-family homes in Sewanee, the physical removal of the old system and installation of the new one can be completed in one working day (6-10 hours). More complex jobs—such as upgrading ductwork, adding zoning, or installing a high-efficiency dual-fuel heat pump—can extend the timeline to 2–3 days. The process includes equipment delivery, safe recovery of refrigerant, removal and disposal of the old unit, setting the new air handler or furnace, connecting ductwork and refrigerant lines, charging the system, and a final performance test.
What size HVAC system do I need for my Sewanee home, and how is that determined?
Proper sizing is based on a Manual J load calculation, which factors in your home’s square footage, insulation levels, window type and orientation, number of occupants, local design temperatures for Sewanee, and even household activities that generate heat. A quick ‘rule of thumb’ based on square footage often oversizes the system, leading to short cycling, poor humidity control, and higher energy costs. Our comfort consultants perform a full load calculation to recommend the right tonnage and airflow so you get consistent comfort and maximum efficiency.
Are high-efficiency heat pumps and dual-fuel systems a good choice for Sewanee’s climate?
Yes. Sewanee experiences hot, humid summers and moderately cold winters. Modern heat pumps with variable-speed compressors provide efficient cooling and heating down to temperatures in the mid-20s°F. Pairing a heat pump with a high-efficiency gas furnace in a dual-fuel setup allows the system to switch to gas heat when outdoor temperatures drop further, maximizing efficiency in every season. This combination often provides the lowest annual operating cost and qualifies for utility rebates and possible federal tax credits.
What does a typical HVAC replacement cost, and do you offer financing or rebates?
Costs vary based on system size, efficiency rating (SEER2/HSPF or AFUE), and any duct modifications, but most homeowners in Sewanee invest between $6,500 and $12,000 for a complete replacement. High-efficiency or dual-fuel systems can be $2,000–$3,500 more but usually deliver 20–40% energy savings. We partner with major lenders to provide 0% APR promotional financing for up to 18 months or low-interest plans up to 120 months. TVA EnergyRight and manufacturer rebates, plus federal tax credits of up to $2,000 on qualifying equipment, can further lower out-of-pocket costs.
Will a new HVAC system lower my energy bills, and what ongoing maintenance will it require?
Upgrading from a 10-SEER unit to a 16-SEER2 or higher system can reduce cooling costs by 30% or more, while a 95% AFUE furnace or high-efficiency heat pump can trim winter heating bills by 15–25%. Variable-speed blowers also improve humidity control and indoor air quality. To keep those savings over the life of the equipment, schedule professional maintenance twice a year—once in spring for cooling and once in fall for heating. Routine service includes cleaning coils, flushing the condensate line, checking refrigerant charge, testing safety controls, and replacing filters, ensuring peak performance and preserving the manufacturer’s warranty.
