Proper air conditioning preventative maintenance is key to making sure your home is ready for the summer. But because your AC unit (hopefully) works throughout all of your house, there is a lot you need to deal with and work on to ensure you’re properly maintaining and keeping your home’s AC unit in tip-top condition. There are many DIY options when it comes to air conditioning preventative maintenance. Here’s what you should do to prepare for record-breaking heats!


Pending the quality of the air filters you buy, you should replace your air filters frequently. This matters because air filters (if not checked regularly) can block the performance of your AC unit. What this means is that you pay more for less high-quality air. And because the summer months already sees high utility bills, you have to ease the burden. A couple of rules of thumb are as follows:

Do Not Clean And Reuse. Air Filters are meant to be a one-time purchase and use. Because they are meant to capture particles at a micro-level, air filters can’t be properly clean like other products in the house. Additionally, because filters deal with bacteria and pollutants, washing air filters leave them vulnerable to mold growth. There are some new filters that are reusable and re-washable; however, they run higher prices and their MERV score (their ability to properly clean) is lower than other filters.

Buy HEPA. HEPA certified filters have much higher MERV scores and are ideal, especially if you have pets at home, children, or people with allergies. Making sure you have a way to reduce air pollutants at every step possible is key to a clean home that runs efficiently.


Air ducts are the ducts lining your house allowing for proper airflow from an AC unit to every corner of your house. Air conditioning preventative maintenance should include your air ducts. If there are any holes or ruptures in your air ducts, AC can leave and be placed in parts of the room that don’t need it while other rooms won’t get enough air. This means that your AC is working harder at a lower effect. Additionally, this leaves your air ducts vulnerable to pollutants and dirt getting in through the cracks, lowering your air quality.


While DIY HVAC maintenance is great, there are some things that you are not able to do when it comes to complete and proper AC maintenance. Namely, if you stumble upon an issue that needs repair, you may need to bring in a professional to remedy the issue.
