In the Mid-South, where the humidity is high and summer temperatures are soaring, a functioning air conditioner isn’t just a luxury—it’s a necessity. Going even a moment without AC can be a painful reminder of how much we rely on properly functioning equipment. The good news is, you can help keep your unit running strong all season by performing simple preventative maintenance and avoiding common AC mistakes.
10 Common Air Conditioner Mistakes to Avoid in the Mid-South
Unless you’re a certified HVAC technician, you probably don’t know the ins and outs of your air conditioning system. The great news is, you don’t have to be a pro to take a few steps to ensure the care of your unit. Just avoid these common air conditioner mistakes.

Skipping a Spring Tune-Up
That mild period in the spring, when you’re not using your heat or your AC, is the perfect time for preventative maintenance. Waiting until the middle of summer, when the Memphis heat is in full swing, will result in long wait times and higher prices from service companies. Come mid-summer you’ll thank yourself for addressing any AC equipment issues. Before the season officially kicks off, get your HVAC unit serviced to ensure it’s ready to handle the summer heat.

Neglecting Your Air Filter
This is one of the easiest tasks you can do, and it has a big impact. Failing to change your return filter regularly not only results in poor air quality but also puts unnecessary strain on your unit. Dirt, debris, and pet hair can get past a clogged filter and wreak havoc on your system. For best results, change your filter every one to three months.
-
Forgetting to Clean the Coils
Once dirt and debris get past the filter, they can clog the coils, which compromises your home’s entire cooling system. Cleaning your AC coils can breathe new life into a struggling system. While many DIYers can handle this themselves, don’t hesitate to call a professional if you’re not comfortable with the job. Always turn off the power to the unit before attempting any service.
-
Incorrectly Programming Your Thermostat
A common myth is that you can save money by raising the temperature when you’re away and then cooling it down when you return. In reality, you’re making your unit work harder to cool the warm house, which puts unnecessary strain on the system. It can also cause moisture issues, leading to mold and mildew. Most experts recommend setting your thermostat to your desired temperature and leaving it there.
The U.S. Department of Energy, through the Energy Star program recommends setting your thermostat to 78 degrees Fahrenheit (25.5 degrees Celsius) when you are home and awake, and higher temperatures when away or asleep. This recommendation is for optimal energy efficiency and cost savings.
-
Planting Too Close to the Outside Unit
We get it—outdoor AC units aren’t the prettiest sight. But be careful about hiding your unit with shrubs and bushes. Most manufacturers recommend keeping plants at least 2 to 3 feet away to ensure optimal airflow and performance.
-
Setting the Thermostat Too Low
Turning your thermostat down to a very low temperature won’t cool your house faster. Your AC unit is designed to cool your home a maximum of about 20 degrees less than the outdoor temperature. So, on a typical 95-degree day in the Mid-South, setting your thermostat below 75 degrees will cause your unit to run constantly without ever reaching the desired temperature.
We know it’s hot – really hot – fall is around the corner though. Give some thought to
an inspection and multi-point furnace check-up before cool temperatures arrive. Avoid a dead system or lengthy, expensive repair scenario during peak need. Get on our schedule for a furnace inspection appointment and keep your furnace running smoothly and safely. Remember, at L&M Services Heating & Air – You want it right, we want it perfect!
