Your HVAC system works overtime during Knoxville’s hot, humid summers — and if you're not giving it the care it deserves, you could be headed for a breakdown. As a trusted HVAC company in Knoxville, TN, we’ve seen it all, from simple maintenance neglect to preventable system failures. Here are seven expert-approved tips to help keep your system running smoothly, efficiently, and reliably all summer long.
1. Change Your Air Filters Regularly
Imagine trying to breathe through a wet washcloth — that’s how your HVAC system feels when the air filter is clogged. Clogged air filters choke off airflow, forcing your HVAC system to strain, overheat, and sometimes even shut down altogether to prevent damage.
As a leading HVAC company in Knoxville, TN, we always tell our customers: changing your air filter is the easiest and most effective way to protect your HVAC investment. Ideally, filters should be replaced every 1–3 months, depending on your home’s air quality, the presence of pets, and system usage.
2. Clean Your Condenser Coils
Your outdoor AC unit also needs clean airflow to function properly. As time goes on, the unit becomes coated with dirt, grass clippings, leaves, and other outdoor debris, which traps heat inside and makes it harder for the system to cool efficiently. This reduced efficiency results in longer run times and higher utility bills.
When you schedule a seasonal tune-up with our HVAC company in Knoxville, TN, we clean your condenser coils to restore optimal performance and extend the life of your system. Members of our GentCare Comfort Club receive this service as part of their maintenance package.
3. Thermostat Myths That Hurt Your System
A common HVAC myth is that lowering the thermostat dramatically will cool your home faster. Unfortunately, that’s not true — and in many cases, it causes your system to freeze up and shut down.
Here’s something many homeowners don’t realize: most HVAC systems are built to cool your home to roughly 20 degrees below the outdoor temperature — not much more. So, on a scorching 95°F day in Knoxville, you might only get your home to about 75°F. Be patient, use ceiling fans to circulate air, and set your thermostat realistically.
If your home is still struggling to cool efficiently, reach out to an HVAC company in Knoxville, TN to inspect your system for deeper issues like refrigerant leaks or airflow restrictions.
4. Schedule Bi-Annual Preventative Maintenance
You wouldn't drive your car for years without changing the oil, right? Your HVAC system follows the same rule of thumb. Bi-annual maintenance helps prevent surprise breakdowns and extends your system’s lifespan.
At our HVAC company in Knoxville, TN, our maintenance visits include:
A clogged drain line can cause water backups that damage floors and ceilings, especially if your unit doesn’t have a float switch. Preventative maintenance gives you peace of mind and saves money in the long run.
5. Duct Cleaning: What You Can’t See Matters
Out of sight, out of mind? Not when it comes to your ducts. With time, your ductwork can become a hidden reservoir for dust, pet hair, pollen, and even microscopic mold spores. These pollutants not only reduce airflow and efficiency but can also aggravate allergies and respiratory issues.
As a reputable HVAC company in Knoxville, TN, we recommend duct cleaning every 3–5 years. Our team uses the Rotobrush Beast — the most powerful duct cleaning system available — to ensure a deep, safe clean that improves:
6. Don’t Close Vents or Doors
Many homeowners think closing off vents or doors to unused rooms will save energy. In reality, it does the opposite. Blocking airflow creates pressure imbalances in your HVAC system, leading to uneven temperatures and increased wear and tear.
To keep your HVAC system operating efficiently, keep interior doors open and ensure all vents are unobstructed. If you notice hot and cold spots in your home, contact an HVAC company in Knoxville, TN to evaluate your duct design or balance the system.
7. Install Surge Protection for Your HVAC
Summer storms in East Tennessee are no joke — and the resulting power surges can wreak havoc on your HVAC system. Just one power surge can wreak havoc on costly parts of your system, such as the compressor or the control board, leading to major repairs or total failure.
That’s why our HVAC company in Knoxville, TN recommends installing HVAC-specific surge protection at your system’s disconnect box. It’s a small investment that could save you thousands in repairs or premature replacements.
Final Word: Comfort Starts with Care
Your HVAC system plays a crucial role in keeping your home comfortable, safe, and livable year-round. With a little attention and help from a professional HVAC company in Knoxville, TN, you can avoid costly repairs, improve your system’s efficiency, and stay cool all summer long.
Whether you’re looking for maintenance, emergency service, or system upgrades, our team is here to help. Don’t wait for a breakdown — schedule your tune-up today and breathe easier tomorrow.
