FAQs
How do I know when it’s time to replace my existing HVAC unit in Duff?
A system older than 12–15 years, frequent or costly repairs, rising energy bills, uneven temperatures throughout the house, and excessive noise are all signs it may be time for a replacement. Our technicians can perform a thorough inspection and provide an honest assessment of whether repair or replacement is the most cost-effective option.
What size HVAC unit do I need for my home?
Proper sizing depends on the square footage of your home, insulation levels, window types, ceiling height, ductwork condition, and local climate in Duff. We complete a Manual J load calculation to determine the exact heating and cooling requirements, ensuring the new system delivers maximum comfort and efficiency without oversizing or undersizing.
How long does an HVAC replacement typically take?
Most residential replacements can be completed in one day. This includes safely removing the old equipment, preparing the site, installing the new indoor and outdoor units, connecting refrigerant lines and electrical, testing airflow, and setting up the thermostat. More complex jobs—such as duct modifications or zoning system installations—may take an additional day.
Will a new HVAC system lower my energy bills?
Yes. Modern high-efficiency units carry SEER2 and AFUE ratings far higher than systems installed 10–15 years ago. Many homeowners in Duff see 20–40% reductions in heating and cooling costs. Variable-speed compressors, smart thermostats, and enhanced airflow design all contribute to lower energy consumption and a smaller carbon footprint.
What rebates or financing options are available for HVAC replacements in Duff?
Utility companies in Tennessee often offer rebates for ENERGY STAR® qualified equipment, and federal tax credits of up to 30% may apply to high-efficiency heat pumps. Our company provides flexible financing plans with low monthly payments and zero-interest promotions for qualified customers, so you can upgrade without straining your budget.
How do I maintain my new HVAC unit after installation?
Change air filters every 1–3 months, keep outdoor condenser coils free of debris, ensure supply and return vents are unobstructed, and schedule professional maintenance twice a year—once before the cooling season and once before heating. Regular tune-ups preserve manufacturer warranties, optimize efficiency, and extend system life.
