How to Avoid Emergency AC Repairs During a Tennessee Heatwave

Amanda Brown • August 1, 2025

It might seem as though the need for emergency AC repairs is an “out of the blue” occurrence, but that’s rarely the case. As is true of any machine, your maintenance and upkeep practices will affect your AC’s performance throughout periods of heavy use. 


On that note, to ensure you can depend on your air conditioner when you need it most, follow these tips for proper emergency AC repair prevention in Tennessee:


Don’t Skip Your AC Tune-Up

It’s easy to lapse on your annual air conditioner tune-ups, but that’s the last thing you’ll want to do before summer rolls back around. The tune-up process reverses wear and tear damage from the previous season. And by tightening fittings, lubricating motors, and cleaning coils, it prepares the system for a return to consistent use. 


Your HVAC technician will also take that time to spot problems. They’ll let you know about repair issues, giving you the advanced notice you’ll need to get the problems fixed before a heatwave strikes.


Keep Up With Air Filter Changes

A clogged air filter is the culprit behind some of the most common AC malfunctions, but you can avoid these issues altogether with monthly filter changes. A clean filter processes treated air at a faster rate to ensure maximum cooling efficiency, and it will also remove more airborne particles, providing better indoor air quality when a heatwave keeps you stuck indoors.


Keep Your Duct Registers Clear of Blockages

Anything that interferes with the flow of treated air can cause a backup in the air conditioner. And once air starts backing up, it will increase condensation and cause your AC’s evaporator coils to freeze. 


Scheduling duct cleaning every three years is, therefore, the most important step when it comes to emergency AC repair prevention in Tennessee, but you’ll still want to clean dust and debris from the duct registers regularly. Additionally, make sure you don’t have furnishings, clothing, or other objects blocking the registers.
