FAQs
How do I know when it’s time to replace my HVAC unit in Decherd?
Most systems in Franklin County last 12–15 years. You should consider replacement if you notice frequent breakdowns, rising utility bills, uneven temperatures, or if your unit still uses outdated R-22 refrigerant. A professional load calculation and inspection can confirm whether repair or full replacement will be more cost-effective in Decherd’s humid subtropical climate.
What size HVAC system do I need for my Decherd home?
Proper sizing requires a Manual J load calculation that factors in square footage, insulation levels, window types, orientation, and even local weather data for Decherd. Oversizing leads to short cycling and humidity problems; undersizing strains components. Our technicians run detailed software, inspect ductwork, and check infiltration rates to recommend the correct tonnage and airflow (CFM) before installation.
How long will an HVAC replacement take, and will I be without heating or cooling?
Most residential replacements in Decherd are completed in one day. We remove the old equipment, set the new condenser or heat pump, install the air handler/furnace, pressure-test and evacuate the refrigerant lines, connect electrical and drain lines, and balance the airflow. Your home may be without conditioning for 4–8 hours, and we schedule work early to minimize discomfort.
Do I need permits or inspections for HVAC replacement in Decherd?
Yes. Franklin County and the City of Decherd require a mechanical permit whenever equipment is replaced, moved, or an electrical circuit is modified. After the installation, the county inspector verifies refrigerant line brazing, condensate drainage, disconnect placement, and that the unit meets the 2021 International Mechanical Code (IMC). We obtain the permit, coordinate inspections, and provide you with a copy of the approval sticker.
Are there energy-efficiency incentives for new HVAC systems in Decherd?
Tennessee Valley Authority (TVA) offers EnergyRight rebates for qualifying heat pumps rated 15 SEER2 or higher and gas furnaces above 95% AFUE. The Inflation Reduction Act also provides federal tax credits—up to $2,000 for high-efficiency heat pumps and $600 for advanced air conditioners. We supply AHRI certificates and help file the paperwork, so you capture every local and federal incentive available.
How much does HVAC replacement cost and what financing is available?
In Decherd, a standard 3-ton heat pump system with new indoor coil averages $7,500–$10,000 installed, while a dual-fuel or high-SEER2 variable-speed system can range from $11,000–$16,000. We offer zero-down financing through TVA EnergyRight, low-interest loans via local credit unions, and promotional 0% APR plans for 12–24 months. All quotes include permits, thermostat, labor warranty, and a one-year maintenance agreement.
