FAQs
How often should I have my air conditioner serviced in Loudon’s climate?
Because Loudon experiences hot, humid summers, we recommend a professional tune-up once a year—ideally in early spring. A technician will clean the coils, check refrigerant charge, tighten electrical connections, and test safety controls. Regular maintenance prevents unexpected breakdowns during peak heat, keeps energy bills in check, and is often required by manufacturers to keep warranties valid.
What size air conditioner is right for my Loudon home?
Proper sizing depends on square footage, window orientation, insulation quality, number of occupants, and even local shading. An HVAC professional performs a Manual J load calculation to determine the exact BTU capacity you need. Oversized units short-cycle, wasting energy and reducing humidity control, while undersized systems run constantly and wear out early. Schedule a load calculation before purchasing to ensure comfort and efficiency.
How can I lower cooling costs without sacrificing comfort?
1) Change or clean filters every 30–60 days so airflow stays unrestricted. 2) Seal and insulate ductwork—leaky ducts can lose up to 30 % of conditioned air. 3) Install a programmable or smart thermostat and set it 2–3 °F higher when you’re away. 4) Use ceiling fans to enhance indoor air movement; you can raise the thermostat another 2 °F and feel just as cool. 5) Consider upgrading to a high-SEER heat pump or AC; each incremental SEER point can cut energy use by roughly 5–7 %.
My AC is 12 years old. Should I repair or replace it?
Most systems last 12–15 years. If your unit is nearing that age, needs a major repair (like a compressor) that costs more than 30–40 % of a new system, or uses phased-out R-22 refrigerant, replacement is usually more economical. New models offer SEER2 ratings up to 20+, translating to significant utility savings and better humidity control. An in-home evaluation lets us compare repair costs, potential energy savings, warranty benefits, and financing to help you decide.
Are rebates or financing available for high-efficiency AC installations in Loudon?
Yes. Tennessee Valley Authority (TVA) and local utilities often provide rebates for ENERGY STAR® or heat-pump installations that meet minimum efficiency standards. Manufacturers run seasonal promotions, and we offer 0 % APR financing plans with approved credit to spread payments over 6–60 months. During your estimate, we’ll identify current incentives and handle the paperwork so you receive the maximum savings.
Can my cooling system also improve indoor air quality?
Absolutely. We can add high-MERV pleated filters, UV germicidal lights, and whole-home dehumidifiers directly to your air-handling system. These upgrades remove pollen, mold spores, and excess moisture—common concerns in Loudon’s humid environment. Maintaining correct humidity (45–55 %) discourages dust-mites and mildew while making the air feel cooler, letting you raise the thermostat a degree or two and save energy.
