FAQs
What size air conditioner do I need for my La Follette home?
Proper sizing is critical in East Tennessee, where both summer heat and high humidity put a heavy load on your equipment. We start with a Manual J load calculation that factors in square footage, number of windows, insulation levels, orientation, and even the number of occupants. For example, two homes with the same floor area can require different tonnages if one has older single-pane windows or less attic insulation. An oversized unit will short-cycle, leaving humidity in the air and driving up power bills, while an undersized system will run constantly and still fail to keep you comfortable. Once the load calculation is complete, we’ll recommend a system—usually between 2 and 5 tons for most La Follette residences—and discuss SEER2 efficiency ratings, sound levels, and budget before installation.
How often should my air conditioner be serviced in East Tennessee’s humid climate?
We recommend two maintenance visits per year—one in early spring and one in fall. High humidity accelerates biological growth on coils and clogs condensate drains, so the standard once-a-year checkup common in drier regions just isn’t enough here. At each visit our NATE-certified technicians will clean the indoor and outdoor coils, clear the drain line, check refrigerant pressures, tighten electrical connections, test capacitors, and verify thermostat calibration. Regular maintenance can cut energy consumption by up to 15 %, extend equipment life, preserve manufacturer warranties, and help you avoid breakdowns during July and August when temperatures routinely reach the 90s.
Why is my air conditioner running but the house still feels sticky?
In La Follette’s muggy summers, an A/C unit must remove both heat and moisture. Common reasons for poor dehumidification include: • Oversized equipment that cools the air too quickly and cycles off before drawing out moisture. • A single-stage system that can’t ramp down to longer, slower cycles. • Dirty evaporator coils or a clogged filter restricting airflow. • Low refrigerant charge that prevents the coil from reaching the correct temperature. • Leaky ductwork pulling humid attic or crawl-space air indoors. We’ll inspect your system, verify sizing, check airflow, and measure static pressure. Solutions range from installing a variable-speed air handler and smart thermostat to adding a whole-home dehumidifier that integrates with your existing ductwork.
Are there energy-efficiency rebates or tax credits for a new A/C system in Campbell County?
Yes. Tennessee Valley Authority (TVA) offers the EnergyRight Residential Services Program, which currently provides rebates—typically $250–$400—for installing a qualifying high-efficiency heat pump or central air conditioner through a participating contractor like East Tennessee Humidity Heating & Air Conditioning. In addition, the federal Inflation Reduction Act extends a 30 % tax credit (up to $600) on ENERGY STAR-certified central A/C systems with SEER2 ≥ 16. Households below certain income levels may also qualify for larger point-of-sale discounts through the forthcoming High-Efficiency Electric Home Rebate Program. We’ll handle the paperwork and provide AHRI certificates so you can claim every incentive available.
How long will installation take, and will I be without cooling during the process?
Most straight A/C replacements in a single-family home are completed in one day. We arrive around 8 a.m., recover the old refrigerant, remove the existing condenser and air handler, set the new equipment, braze or press-fit the line set, pull a deep vacuum, charge with factory-specified refrigerant, and test the system. If new ductwork, an electrical upgrade, or a pad relocation is required, the job may extend to two days. We coordinate our schedule so your downtime is as short as possible—usually just a few hours while we switch out components. Portable cooling units are available at no charge for medically fragile customers or extreme-heat forecasts.
What can I do to improve indoor air quality along with cooling?
Cooling alone doesn’t address all IAQ concerns such as pollen, mold spores, and odors common in East Tennessee’s humid environment. Consider these add-ons during your A/C upgrade: • A high-MERV or HEPA media filter cabinet to capture fine particulates. • UV-C lights mounted near the evaporator coil to inhibit microbial growth. • A whole-home dehumidifier to keep relative humidity between 45 % and 55 %—ideal for comfort and mold prevention. • ECM variable-speed blowers that allow continuous low-speed circulation, which evens out temperatures and pushes more air through filters. • Sealed and insulated ducts to prevent drawing pollutants from attics or crawl spaces. Our comfort consultants can test your home’s air, discuss specific allergy or asthma concerns, and design a turnkey IAQ package that integrates seamlessly with your new air conditioning system.
