4 Signs Your AC System Is Inefficient in Highland Park, IL

It’s common for summer temperatures in Highland Park, IL, to reach 80 degrees or higher. That’s why you need an efficient air conditioner to keep you cool and comfortable. If you’re experiencing any of the four events listed below, you might have an inefficient AC system:

Your Home Never Reaches the Set Temperature

If your AC system is unable to achieve your desired temperature, it’s likely working overtime to cool your home. Even if you do achieve the temperature you want, an inefficient air conditioner will take longer to get the job done. Evidence of this is an uncomfortable home and higher energy bills.

The Thermostat Is Acting Strange

To provide efficient cooling, your AC system needs a good thermostat. But a faulty thermostat might send the incorrect information to the cooling system. As a result, the temperature you expect isn’t what the air conditioner provides.

It’s not always easy to determine that a thermostat is faulty. This is especially true if you have an old and outdated manual thermostat. An HVAC maintenance service technician can help determine if you need to replace or repair your thermostat.

There Are Visible Drainage Problems

If there’s a buildup of water or visible leaks around your AC system, this could mean that drainage problems are affecting its efficiency. A blocked condensation line is often the source of draining problems.

The AC Filter Is Extremely Dirty

It’s common for an air conditioner filter to get dirty, but it shouldn’t have layers of dirt and grime caked on it. The AC system will have a challenging time producing cool air if the filter is too dirty. This can also cause dirt and debris to accumulate within the system and eventually lead to damage.
