It’s officially springtime, which means warmer weather is on the horizon! As you break out the sun hats and sunglasses, don’t forget about your home air conditioner. As the temperatures rise, it’s essential to ensure your air conditioner is in top working condition. After all, no one wants to be stuck in the heat wave without a properly functioning AC unit!
However, maintaining your AC unit doesn’t have to be a daunting task. With this air conditioner maintenance checklist, you can keep your unit running smoothly.
Replace the Air Filter
The filter is responsible for trapping pollen, dust, and other allergens, so they don’t circulate through your home. A dirty filter will reduce your AC unit’s efficiency and cause it to overheat. To clean or replace the filter, remove it from its housing and vacuum away any debris. If the filter is noticeably damaged or torn, it’s best to replace it entirely.
Change the AC air filter every 1-3 months or as needed. It is best to do it in the spring or fall when your air conditioner is not in use as often.
Check and Clean Coils
The evaporator and condenser coils are responsible for transferring heat from inside your home to the outside air. Over time, these coils can get dirty and dusty, reducing efficiency. To clean the coils, remove them (careful not to damage them) and clean them with a soft brush.
You can also use a specifically designed coil cleaning solution to help loosen any stubborn dirt or grime. Once the coils are clean, reinstall them before moving on to the next step.
Clean the Fins
The fins are located outside the evaporator coil, and help dissipate heat as air passes through them. These fins can easily become bent or damaged, which can limit airflow and cause your AC unit to overheat. Use a soft brush or fin comb to straighten out any bent fins, being careful not to damage them. Once you’ve straightened out the fins, vacuum away any dirt or debris that may have accumulated on them.
Clear the Area Around Your AC Unit
Your AC unit needs airflow to work correctly, so be sure to clear away any plants, branches, leaves, or other debris that may be blocking its vents. Also, take a moment to clear away any cobwebs or insects that may have taken up residence around your AC unit over wintertime!
Clean the Drain Pan and Drain Line
The drain pan collects water that condenses on the evaporator coils. Over time, this water can become stagnant and produce mould or mildew. To clean the drain pan, remove it (being careful not to damage it) and wash it with a mixture of soap and water. If any mould or mildew is present, you can use a specifically designed cleaner to help remove it.
Once the pan is clean, check the drain line for any clogs. The drain line carries water away from the pan and out of your home, so it must be clear of any obstructions. If you notice any clogs, use a plumbers’ snake or air compressor to clear them away.
Check the Thermostat
The thermostat is responsible for regulating the temperature in your home, so it must function correctly. If your AC unit isn’t cooling your home evenly, or if the temperature in your home fluctuates, there may be an issue with the thermostat. To check the thermostat, remove it from its housing and use a multimeter to test the continuity of the wires. If there is no continuity or the reading is erratic, you will need to replace the thermostat.
While you have the thermostat out, it’s also a good idea to vacuum away any dust or debris that may have accumulated on it.
Schedule An Annual AC Tune-Up
Even if you do all of the above maintenance tasks, it’s still a good idea to schedule an annual AC tune-up with a professional. During a tune-up, a technician will thoroughly inspect your AC unit and perform any necessary repairs or replacements. This preventative measure can save you a lot of money by catching minor problems before they turn into big ones!
Following the air conditioner maintenance checklist above can keep your AC unit in top shape for many years! Not to mention, you’ll also enjoy improved cooling performance and lower energy bills. So what are you waiting for? Get started on your AC maintenance today!
