A Homeowner’s Guide to Air Conditioner Maintenance


To save money on AC repair in Chicago , it’s important to schedule air conditioning maintenance at least once per year. Routine AC maintenance not only helps to save you money on AC repairs, but it also improves the efficiency and reliability of your AC unit. Continue reading to learn some tips that will help you keep up with air conditioner maintenance.


Change Filters

Clogged filters reduce the efficiency of air conditioners, so it’s important to replace the filter once a month during cooling season, or clean it every month if you have a washable filter. When you replace an AC filter, remember that filters that offer better filtration can improve indoor air quality, but require more energy.

Fix Duct Leaks

Did you know that 30 percent of airflow can be lost through poorly-insulated ducts? To locate air leaks, light a stick of incense and hold it near duct connections. If you see the smoke blowing around, you have a leak that needs to be fixed.

Reduce the AC System’s Workload

There are a number of steps you can take to ease your AC’s workload. Purchase a programmable thermostat if you don’t have one already. This device will allow you to set a higher temperature for when you’re out of the home. Insulate the ducts in your home with spray foam, rigid-foam insulation, or batt insulation. Keep the blinds or shades closed during the day, and use fans to increase your indoor comfort without overworking your AC unit.

Keep the Compressor and Condenser Clear

The AC compressor and condenser are typically located outside, so it’s not uncommon for them to become covered by leaves, branches, grass, and shrubs that reduce efficiency and reliability. Check the compressor and condenser every week during cooling season to be sure there’s at least 2 feet of clear space in every direction.

Schedule an AC Tune-Up

Call a reputable AC repair company serving Chicago and ask to be put on a yearly cleaning schedule, preferably before cooling season starts. This service will include cleaning and checking the coils, blowers, and fans, and inspecting the controls, safeties, refrigerant, and pressures. The HVAC repair specialist will also check operating temperatures, adjust and replace fan belts, lubricate the motor and bearings, and clean or replace the filters.
