Spring into Cool: AC Maintenance for Summer Comfort

The temperature is rising, just as expected; this is Spring, you know! Before long, warm weather activities will be our norm, activities that take us outdoors and away from routine “indoor” activities. When the temperature gets too hot, though, we relish the opportunity to come inside to find relief from the heat and humidity. Relief comes in the form of a residential air conditioner, making our homes a cool oasis. If you want your air conditioner to function all summer long, don’t neglect proper AC maintenance.

Start Outside

The outdoor air conditioning component is called the condenser unit. Its main function is to release the heat from inside the house into the outside. A large fan in the center of the unit pulls air across the tubes filled with hot refrigerant gas. Homeowners must keep the condenser coils free from dirt and debris; here are some tips to help keep it clean.

  • Ensure that shrubs and grass are trimmed at least 2 feet away from all sides of the condenser. This provides adequate air movement for cooling.
  • Once or twice per year, remove the cover plates for the condenser and observe the surfaces. As the fan draws water through the coils, it also draws dust, pollen, grass clippings, and leaves.
  • Use a garden hose to gently wash the debris and dust away. This will promote the transfer of heat and help cool the indoor space.

Check the Thermostat

The ON/OFF switch for the air conditioner is called the thermostat. The thermostat is quite innovative and adaptable. Here are a couple of maintenance tips to help care for your thermostat.

  • The thermostat is a small computer, and it runs on battery power. To keep the system running properly, make sure to change the battery annually.
  • Learn to program the computer in the thermostat; with just a little effort, it is possible to schedule temperature changes that will make your family comfortable and save a little money.

Change the Air Filter

Since the air conditioner is moving so much air, the engineers installed an air filter to help clean the air as it moves. The filter traps dust, pollen, dander, and other airborne particles. However, the collected particles will eventually clog it, preventing the free flow of air. Since air conditioning requires great amounts of airflow, a clogged filter will inhibit the system from cooling properly. Here are the details for changing air filters.

  • Find the air filter near the base of the air handler unit; it is the place where air from the home enters the central air conditioner.
  • Air filters can be found in home improvement, hardware, and many big box stores. Make sure to purchase a supply of the right size filters for your air conditioner.
  • The filter needs to be changed at least every three months to ensure the system performs properly.

Schedule Professional AC Maintenance

Homeowners can handle the simple tasks, but the air conditioner needs preventative maintenance by an HVAC technician. Maintenance ensures the components function properly and efficiently. Spring season is the perfect time to schedule maintenance. During the Summer months, the technicians get quite busy making repairs and installing new systems. A well-maintained system:

  • Costs less to keep the home comfortable
  • Requires fewer repairs
  • Keeps the indoor air cleaner
  • Gives longevity to the air conditioner

Beat the Heat: Get Your AC Ready This Spring with AC Maintenance

To ensure a comfortable and efficient summer, homeowners should prioritize spring AC maintenance, including cleaning the condenser, checking the thermostat, and regularly changing air filters. While DIY tasks are helpful, scheduling professional maintenance is crucial for optimal performance and longevity. Investing in preventative care now will minimize costly repairs and maintain a cool, healthy home throughout the hot season.
