FAQs
How do I know it’s time to replace my HVAC system instead of repairing it?
Several warning signs point toward replacement: the unit is 10–15+ years old, repair costs are approaching 40–50 % of the price of a new system, utility bills keep rising despite regular maintenance, the unit still uses R-22 refrigerant, or comfort problems such as uneven temperatures and excessive humidity persist. In Soddy-Daisy’s hot, humid summers and cool winters, an aging or inefficient system can quickly drive up operating costs. During a free in-home assessment, our technicians measure system performance, review past repair history, and calculate life-cycle costs to help you decide whether repair or full replacement makes better financial sense.
What size HVAC unit does my Soddy-Daisy home need?
Proper sizing is critical—an undersized unit will run nonstop and an oversized unit will short-cycle, wasting energy and shortening equipment life. We perform a Manual J load calculation that factors in square footage, number of windows, insulation R-values, air infiltration rates, occupants, and local design temperatures (92 °F summer / 22 °F winter for Soddy-Daisy). This calculation determines the exact BTU capacity for both heating and cooling so you get balanced comfort, lower energy bills, and maximum equipment longevity.
How long does a typical HVAC replacement take?
Most residential replacements can be completed in one day. The timeline breaks down like this: 1–2 hours to remove the old indoor and outdoor units, 1 hour to modify or replace the line set and drain lines, 2–3 hours to set the new equipment, connect electrical, and pressure-test the refrigeration circuit, and 1–2 hours for vacuum pull-down, refrigerant charging, thermostat setup, and a full system start-up checklist. More complex jobs—such as duct modifications, zoning upgrades, or attic installations—may add an extra day.
Are there energy-efficient options that qualify for rebates or tax credits?
Yes. Many high-efficiency heat pumps and air conditioners with SEER2 ratings of 16.0+ (formerly 18 SEER) and gas furnaces at 97 % AFUE or higher qualify for federal tax credits under the Inflation Reduction Act—currently up to $2,000 for heat pumps and $600 for central A/C or furnaces. Local utilities like EPB and TVA’s EnergyRight program also offer cash rebates for qualifying equipment and duct sealing. We handle the paperwork and provide all model numbers and AHRI certificates so you can claim every available incentive.

How much will a new heating and air conditioning unit cost in Soddy-Daisy?

As a general range, a 2- to 3-ton 15 SEER2 split heat pump starts around $6,800 installed, while a high-efficiency 20 SEER2 variable-speed system can run $11,000–$14,000.
