Summers in Indianapolis can be warm, humid, and long. During the hottest months from May to September, the average daily high temperature is above 75°F. During the warmest month of the year, July, the average high here is 85°F.If you live in Indianapolis, it's likely that you have an air conditioning unit on your property. AC units help not only to improve indoor comfort and reduce high humidity, but they also improve air quality, reduce the likelihood of parasites and insects, and reduce the risk of dehydration.In this blog post, we will highlight 4 common AC repair mistakes that you should avoid making. In order to get the most out of your AC unit, it's important to follow these steps.

1. Skipping the Maintenance Schedule

Depending on how frequently you use your AC unit, you should schedule once or twice-year maintenance checkups with a professional AC contractor. Even if there are no signs that something is wrong with your unit, these tune-ups are important to ensure that the unit stays in tip-top condition.With the summer months coming on the horizon, now is really the most opportune time to schedule an AC unit tune-up.

2. Ignoring the Air Filter

Changing the air filter is something you can—and should—do yourself at home. In an AC unit, the air filter serves as a barrier, helping to prevent contaminants from circulating with the air or entering the system. They help to block out dust, dirt, pet hair, lint, mold, bacteria, and more.You should aim to change your AC's air filter at least once every 3 months. If you live in a dusty climate or have household pets, you may need to change it more frequently, such as every 1 or 2 months.

3. Ignoring Warning Signs

If you notice an issue with your AC unit, don't simply ignore it as the problem is likely to become worse. This can result in having to pay more for repairs in the future. Some common warning signs that there is an issue with your AC unit include:

  • Strange noises
  • Bad odors
  • Insufficient airflow
  • Warm air
  • Rapid cycling
  • Higher than usual energy bills

It pays to be proactive in scheduling repairs when you notice any of these common AC issues.

4. Attempting DIY repairs

There is nothing wrong with having a DIY spirit, however, AC units can be complicated and any attempts to resolve an issue may only make things worse.While you should be proactive in changing the air filter, other issues should be left to the professionals, like LCS Heating and Cooling in Indianapolis.
