A malfunctioning AC can be more than a minor inconvenience. A bad AC will use more energy than usual, causing your electricity bill to skyrocket. AC failure is a common cause of poor indoor air quality.

Every homeowner should make AC maintenance a priority. Regular AC maintenance prevents problems from occurring and is your best defense against breakdowns. A well-maintained AC is reliable and will run at optimum capacity. You will stay cool and save money with an efficient, well-maintained AC.

Follow these tips to maintain your AC.

Replace Your AC Filters Regularly

AC filters trap airborne contaminants and dust, dander, and pollen. It’s not uncommon for filters to become clogged with these contaminants over time. A clogged AC filter can do more harm than good.

Clogged filters are a common cause of restricted airflow. When your filters become clogged, your AC has to work harder and longer, causing your energy bill to skyrocket. They can even cause your AC to overheat and shut down.

To prevent performance problems, replace your filters every 90 days. If you or a family member has an allergy, consider replacing your filters more frequently (every 45 days).

Maintain Your Outdoor Unit

Your AC’s outdoor unit is exposed to the elements. Over time, dust can build up in your outdoor unit, negatively affecting its efficiency.

Keep the area around your outdoor unit clean. Trim vegetation back around the unit. Clean coils with foaming condenser coil cleaner. Let the cleaner sit for a few minutes and then rinse the condenser coil with a hose. Straighten out bent coil fins. Remove debris from your unit.

Keep Up with Maintenance

Have your contractor inspect and maintain your AC once every year. If you are thinking of skipping maintenance because your AC is working properly and does not show any signs of distress, let us tell you that some signs of AC problems are less obvious. You can miss these signs, your technician won’t.

During tune-up sessions, your technician will fix current problems and nip potential cooling issues in the bud. The professional will:

  • Clean your coils and the outdoor unit
  • Lubricate moving parts to reduce friction between them
  • Check electrical connections
  • Check your AC’s refrigerant level and top it off if required
  • Clean or replace AC filters

Keep Your Drain Line Clean

Over time, your AC’s drain line can become clogged. A clogged drain line can cause the water in your drain pan to overflow. If left unaddressed, the problem could lead to serious structural damage.

To keep your drain line clean, flush it with a small amount of bleach every 30 days. If algae or mold has plugged the line, a basic wet/dry vacuum will suck away the obstruction.
