You are viewing the Nashville, TN location.
There’s nothing quite like a Tennessee summer afternoon when the heat index climbs, the humidity settles in, and suddenly your air conditioner stops working. If you’re searching for emergency AC repair in Nashville, TN, chances are you need answers fast. Before panic sets in, there are a few simple things you can safely check on your own that may restore your cooling system and save you time.
Start With the Thermostat
It may sound obvious, but thermostats are often the source of unexpected cooling problems. First, confirm the thermostat is set to “cool” and not accidentally switched to “heat” or “fan.” Then check the temperature setting to make sure it’s lower than the current indoor temperature.
If your thermostat screen is blank, the batteries may need replacing. Many homeowners forget that battery-powered thermostats can stop communicating with the system when the batteries die. After replacing them, wait a few minutes to see if the system restarts.
Smart thermostats can also lose Wi-Fi connections or experience software glitches after a power surge. A quick reset may solve the issue and get your AC running again.
Check the Electrical Panel
Air conditioners require a significant amount of electricity to operate, especially during extreme heat. Sometimes the system shuts down because a breaker has tripped.
Locate your home’s electrical panel and look for any breakers that are out of alignment or sitting between the “on” and “off” positions. If you find one connected to your AC system, switch it fully off and then back on.
If the breaker trips again immediately, avoid repeatedly resetting it. That can point to a larger electrical or mechanical issue within the system. In that case, it’s best to stop troubleshooting and call a professional technician.
Don’t Forget the Air Filter
A clogged air filter is one of the most common causes of AC trouble during summer. When airflow becomes restricted, your system can overheat, freeze up, or shut down entirely.
Pull out the current filter and hold it up to the light. If you can barely see through it, it’s time for a replacement. Installing a clean filter may improve airflow enough for the system to recover.
After changing the filter, give the system about 10 to 15 minutes before checking whether cool air begins flowing through the vents again.
When DIY Checks Don’t Solve the Problem
