Summer is coming, and the last thing you want is for your air conditioner to give out when you need it most. Read on to learn what to look for, what to fix, and when to call in a pro.

Replace Your Air Filter First

A clogged air filter is behind more AC problems than almost anything else. When the filter is packed with dirt, it restricts airflow, making your system work harder than it should. Check your filter every 30 days throughout the summer, and replace it at least once a month if you run your AC a lot.

Clean the Condenser Coils Outside

Your outdoor unit pulls in a lot of air, and over time the condenser coils can get dirty. This buildup acts like insulation and can stop your system from releasing heat properly. Turn the unit off at the breaker, remove the outer casing, and gently rinse the coils with a garden hose from the inside out. Avoid pressure washers since the fins bend easily. Doing this just once a season can make a noticeable difference in how efficiently your system runs.

Check and Clear the Condensate Drain Line

All air conditioners produce condensation, which drains through a small pipe that can get clogged over time. A blocked drain line can cause water to back up, which can shut off your AC entirely and overflow and damage your ceiling or floors. Find the drain line near your indoor air handler, and flush it with a cup of distilled white vinegar every few months to keep it clear.

Look at Your Thermostat Settings

Before assuming your AC is broken, check your thermostat. Make sure it’s set to “Cool” and not “Fan” only. If it runs on batteries, replace them regularly. If you have a smart thermostat, check to see if the scheduled setting is overriding your manual adjustments. A surprising number of service calls turn out to be thermostat issues that take fewer than five minutes to resolve.

Know When to Call a Professional

Some repairs should be left to the professionals. If your system is blowing hot air after you have checked the filter and thermostat, you hear grinding or squealing noises, or ice is forming on the refrigerant lines, it’s time to call a licensed HVAC technician. Low refrigerant, failing compressors, and electrical issues all require a technician with professional tools and training who can make repairs safely.

Keeping your AC in good shape doesn’t require a lot of time or technical skill. Keeping the filters and coils clean, clearing the drain line, and double-checking your thermostat can prevent common breakdowns. Following these simple maintenance steps will help you stay cool all summer without the stress of an unexpected repair bill.
