Before turning on your air conditioning system for the first time this season, there are several things you will want to do first. Even if you have already been running your AC this summer, it is worthwhile to still do these things, as they can help you avoid costly emergency air conditioning repair bills later.

Safety Tip: Make sure to shut off the power to the AC unit before working around it. You will want to turn the unit off at the thermostat, as well as the breaker box. Keep in mind, the breaker switch is not always in the main box but in a separate box next to the outdoor AC unit.

  1. Clean and remove any debris from around the unit. Make sure there are no leaves, twigs, grass, or anything else around the unit, as these can cause problems with proper air ventilation and cooling coil operation. Remember to trim back any trees that are growing over or near the outdoor unit, too.
  2. Inspect the outdoor lines, wiring, and drain line. Make sure none of the lines and wiring that run from the unit into the home are cracked, broken, or have exposed areas. With the drain line, most are removable, so you can clean it out by running water through it.
  3. Inspect any ductwork you can see. If you have access to ductwork in the basement or crawl space under the home, look for any areas that seem loose or if there are gaps in between sections, as well as any holes. These things can decrease the efficiency of the system, as cool air will escape.
  4. Have your ducts If you notice your air vents look dusty and dirty, chances are the ducts need to be cleaning. Another telltale sign is if dust accumulates at a very fast rate and in large amounts around your home.
  5. Change the air filter. If you haven’t changed your air filter recently, now is a good time to do so before turning on the air conditioning. Some systems will have more than one filter. Most systems have a return air filter located in front of the air return vent. Some systems also have a secondary air filter located next to the blower motor, which is part of your furnace but is used to blow cool air through your home in the summer.

  1. Upgrade your thermostat if it is not a programmable model. Programmable thermostats give you better control over your heating and cooling system. By setting different temperatures for different times of the day and night, you can reduce your energy usage and lower your heating and cooling bills. There are many new technologies you will discover with certain models, like ones that allow you to control them directly through an app on your smartphone.

If you lack the DIY-skills to do these things, or simply lack the time, you can make sure they are taken care of by scheduling air conditioning system maintenance through A+ Services.
