FAQs

What kinds of air-conditioning systems can you install in Sewanee homes?

We install a full range of residential and light-commercial cooling solutions, including high-efficiency split-system air conditioners, air-source heat pumps that both heat and cool, ductless mini-split units for rooms without ductwork, and packaged rooftop or ground-mount units for space-constrained properties. Each option can be matched to your home’s size, existing ductwork, and comfort goals, and we’ll explain the pros and cons—such as up-front cost, efficiency, and zoning capability—during your free estimate.

How do I know what size air conditioner my home needs?

Proper sizing is determined with a Manual J load calculation, which evaluates square footage, insulation levels, window type, sun exposure, number of occupants, and even local weather data for Sewanee’s humid summers and mild winters. Undersized units run constantly, while oversized systems short-cycle and waste energy. During our survey we’ll gather the needed data, run the Manual J software, and recommend a unit—typically between 1.5 and 4 tons for most Sewanee residences—that will maintain 75 °F/50 % RH on a 95 °F design day.

How long does a typical air-conditioning installation take?

Most straight furnace-and-coil replacements with an outdoor condenser are completed in a single day—about 6–8 hours, including set-up, installation, evacuation, charging, and start-up testing. If we’re adding new ductwork, relocating the air handler, or upgrading your electrical service, the project can extend to 2–3 days. We provide a written timeline up front and keep you informed of progress so you’re never guessing when the cool air will be flowing.

Are high-efficiency air conditioners worth the investment in Sewanee’s climate?

Yes. Units with SEER2 ratings of 16–20 can lower summer cooling bills by 20–40 % compared with older 10–13 SEER equipment. Electricity rates in Tennessee average about 12 ¢/kWh, so a 3-ton 18 SEER2 system can save roughly $200–$300 per year versus a standard 14 SEER2 unit. Additionally, federal Inflation Reduction Act tax credits of up to $2,000 and Tennessee Valley Authority (TVA) rebates of $150–$500 can shorten the payback period to 4–6 years while providing quieter operation and better humidity control.

Do I need permits or inspections for a new AC installation in Sewanee?

Franklin County requires a mechanical permit for any HVAC replacement or new installation. Electrical changes, such as adding a dedicated breaker, also require an electrical permit. Our team handles the paperwork, pays the permit fees, schedules county inspections, and provides you with all approved documentation for your records. We also follow International Residential Code (IRC) and manufacturer guidelines to keep your warranty fully intact.

What maintenance should I plan for after the system is installed?

Replace or clean the air filter every 30–90 days, keep the outdoor condenser clear of leaves and grass, and schedule a professional tune-up each spring and fall. Our tune-ups include coil cleaning, refrigerant pressure checks, thermostat calibration, amp-draw testing on motors, and condensate-drain flushing—tasks that maintain efficiency, reduce breakdowns, and satisfy most manufacturers’ warranty requirements. We offer affordable maintenance plans that provide two visits per year, priority service, and 10 % off any repair parts.
