FAQs
Why is balanced ventilation so important for homes in Collegedale’s humid climate?
Collegedale sits in the Tennessee Valley, where summer humidity regularly exceeds 70 %. Without controlled ventilation, moisture builds up indoors, encouraging mold, dust-mites, and musty odors. A balanced ventilation system—such as an Energy Recovery Ventilator (ERV)—exhausts stale, humid air while bringing in fresh outside air and transferring most of the heat and moisture between the two streams. This keeps indoor relative humidity in the ideal 40–55 % range, improves comfort, and protects the structure of your home from condensation-related damage.
What advantages will I see if I upgrade to a high-efficiency heat pump or air-conditioning system?
Modern heat pumps rated 16–20+ SEER2 and 8–10 HSPF2 can cut cooling costs by as much as 30 % compared with 10- to 15-year-old units. Variable-speed compressors run at the exact capacity needed, so they remove more humidity on muggy Collegedale days, keep temperatures even from room to room, and operate quietly. In winter, advanced heat pumps provide reliable heating down to 5 °F, so you rely less on electric resistance back-up heat. Utility rebates and federal tax credits of up to 30 % (under the Inflation Reduction Act) often offset a significant portion of the upgrade cost.
How often should I change my HVAC filter, and which type is best for allergy sufferers?
For average households, change 1-in. pleated filters every 60–90 days. If you own pets, smoke, or have allergy sufferers, replace them monthly. Consider a media cabinet that holds a 4- to 5-in. MERV-11 or MERV-13 filter; these capture 90 % of particles down to 1 µm, including pollen and most mold spores, without restricting airflow. High-end HEPA bypass filters remove 99.97 % of 0.3 µm particles and are ideal for severe asthma or immunocompromised residents, but they must be professionally installed to avoid excessive static pressure on the blower motor.
Which indoor air-quality add-ons do you recommend and how do they work?
• UV-C Germicidal Lamps: Mounted inside the air handler, they bathe the coil and drain pan in ultraviolet light to inhibit biofilm growth and kill airborne bacteria and viruses. • Electronic Air Cleaners or Polarized Media: Use an electrostatic charge to attract particles as small as 0.1 µm and require only annual maintenance. • Energy/Heat Recovery Ventilators (ERV/HRV): Exchange stale indoor air for fresh outdoor air while capturing up to 80 % of the energy in the exhausted air, reducing heating and cooling losses. • Whole-House Dehumidifiers: Tie into the ductwork to wring out excess moisture independently of the air conditioner—perfect for shoulder seasons when it’s muggy but not hot.

How can I lower energy bills while keeping my home comfortable year-round?
1. Program your thermostat to 78 °F in summer and 68 °F in winter when you’re home, and 4–6 ° higher/lower while you’re away. 2. Seal duct leaks; ENERGY STAR studies show the average system loses 20–30 % of conditioned air through gaps. 3. Add R-38 attic insulation and seal attic penetrations to block heat gain and loss. 4. Install smart vents or zoning dampers to condition only occupied areas. 5. Maintain proper refrigerant charge and clean coils twice a year to restore up to 15 % cooling efficiency. 6. Replace older single-speed equipment with an ENERGY STAR variable-speed heat pump or dual-fuel system optimized for Collegedale’s temperature swings.
What preventive maintenance services do you offer, and how do they extend my HVAC system’s life?
Our biannual Comfort Care Plan includes a 21-point inspection each spring and fall: • cleaning condenser and evaporator coils • checking refrigerant charge • lubricating motors and bearings • tightening electrical connections • testing safety controls • flushing condensate lines • verifying airflow and static pressure • changing or washing filters. Regular maintenance cuts unexpected breakdowns by up to 95 %, keeps manufacturer warranties valid, improves efficiency 10-15 %, and can add 3–5 years to the life of your furnace, heat pump, or air conditioner.
