Why Is My AC Working Overtime in August?

Ah, August in Nashville! The sun is shining, the music is playing, and the temperatures are soaring. But while you’re enjoying the summer vibes, there’s one thing that might be working a little too hard: your air conditioner. If you’ve noticed your AC running constantly or inefficiently, you’re not alone. Let’s dive into the common reasons why this happens and how you can troubleshoot them.

1. Soaring Nashville Temperatures

Nashville is known for its hot and humid summers. The average temperature in August can reach the high 80s or even 90s. Your AC has to work harder to maintain a comfortable indoor temperature, especially during peak hours.

Quick Fix: Ensure your home is well-insulated. Check for drafts around windows and doors and consider using blackout curtains to block out the intense midday sun.

2. Dirty or Clogged Filters

A dirty filter restricts airflow, causing your system to work harder to cool your home. This not only increases your energy bill but also wears out your AC faster.

Quick Fix: Replace or clean your filters every 1-3 months, especially during heavy usage months like August.

3. Thermostat Issues

Sometimes, the problem isn’t with the AC unit itself but with the thermostat. If it’s not calibrated correctly, it might cause your AC to run non-stop.

Quick Fix: Check if your thermostat is set to the right temperature. If it’s an older model, consider upgrading to a programmable or smart thermostat for more accurate readings.

4. Refrigerant Leaks

Low refrigerant levels can cause your AC to run continuously. This is because the refrigerant is what cools the air, and if there’s not enough of it, your system will struggle.

Quick Fix: If you suspect a leak, call a professional. Handling refrigerants requires expertise and can be hazardous.

5. Aging AC Units

Like all appliances, air conditioners have a lifespan. An older unit might not be as efficient as it once was, especially if it hasn’t been regularly maintained.

Quick Fix: Schedule regular maintenance checks. If your unit is over 10 years old, consider investing in a newer, more energy-efficient model.

6. Inadequate Size

If your AC unit is too small for your home, it will run constantly trying to cool it. On the other hand, a unit that’s too big will cycle on and off frequently, which is also inefficient.

Quick Fix: Consult with an HVAC professional to ensure you have the right size unit for your home.

Wrapping Up

Nashville’s summer heat is no joke, and neither is an overworked AC. By understanding the common issues and addressing them promptly, you can ensure a cool and comfortable home without the stress of skyrocketing energy bills.
