As the temperatures begin to climb in the New River Valley and across East Tennessee, there is one thing every homeowner knows for certain: our summers are intense. Between the soaring heat waves and the thick, heavy humidity characteristic of our region, your air conditioning system is about to face its most demanding months of the year.


At Ashton Britt Service Company, we’ve been keeping East Tennessee homes and businesses comfortable since 2003. We know that the worst time to discover an HVAC issue is in the middle of a July heatwave. By taking a few proactive steps now, you can avoid emergency repair calls and ensure your system runs efficiently all season long.


1. The "Humidity Factor": Why East TN is Unique


In many parts of the country, dry heat is the primary challenge. Here in East Tennessee, humidity is the real enemy. High humidity makes the air feel much hotter than the thermometer reads, forcing your AC to work harder to remove moisture and cool the air.


  • Watch for Mold/Musty Odors: Humidity often leads to microbial growth in your ductwork or on evaporator coils. If you smell something "off" when the AC kicks on, it’s a sign your system needs a professional cleaning.
  • The Dehumidification Battle: If your AC runs constantly but your home still feels "clammy," your system might be oversized or have a drainage issue.


2. The Essential Pre-Season Checklist


Before the peak of summer hits, take a walk around your home. A few minutes of inspection can save you hundreds in repair costs:


  • Clear the Perimeter: Ensure your outdoor unit (the condenser) has at least 2–3 feet of clearance. Trim back overgrown grass, shrubs, and weeds. Debris limits airflow, forcing the compressor to work harder and increasing your energy bill.
  • Check the Air Filter: This is the #1 cause of AC breakdowns. A dirty filter restricts airflow, which can lead to frozen evaporator coils. Change it every 30 days during the summer if you have pets or suffer from allergies.
  • Test Your Thermostat: Don't wait for a 90-degree day to find out your thermostat is malfunctioning. Test it early to ensure it communicates properly with your furnace and AC.


3. Don't Ignore the "Warning Signs"


HVAC systems rarely fail without warning. If you notice any of these symptoms, call a professional before the system gives out completely:


  • Strange Noises: Grinding, squealing, or rattling sounds usually point to loose parts, worn-out bearings, or motor issues.
  • Frequent Cycling: If your AC turns on and off every few minutes, it’s "short cycling." This is a major efficiency killer and puts immense stress on the compressor.
  • Higher-Than-Average Bills: A sudden spike in your electric bill is often the first indicator that your system is losing efficiency due to a refrigerant leak or a failing component.


4. Why Professional Maintenance Matters


While DIY checks are helpful, there is no substitute for a professional tune-up. Our technicians at Ashton Britt go beyond the basics. We check your refrigerant levels, inspect electrical connections for heat damage, and ensure your condensate drains are clear—a critical step to prevent water damage in your home.
