As you probably know already, your air conditioning system needs regular maintenance in order to perform efficiently and effectively. Neglecting annual HVAC maintenance appointments and monthly maintenance will result in gradually decreasing AC performance and increases in your energy bill.
During summer, your air conditioner is working harder than ever, making it more important than any other time of year to conduct AC maintenance.
Summer Air Conditioning Maintenance Guide
1. Air Conditioning Filters
The most important thing that you can do as a homeowner to make sure your HVAc system is operating properly is to make sure your air filters aren’t dirty and clogged. Create calendar and phone reminders to check your air filters every 30 days. In the summer, they should be replaced every 30-90 days, depending on the type of filter you have. Never wait more than 90 days to make an air filter replacement.
A dirty air filter will reduce airflow to your system, which can result in a variety of problems including frozen evaporator coils, dirty air ducts, clogged condensate drain lines, insufficient cooling, higher energy bills, and much more.
Where can I find my air filter?
For most central air conditioning units, you can find your air filter connected to your duct system. If you have an air cleaner, such as UV germicidal irradiation, then it the filter is very close by. Other possible locations for your air filter include:
- At the ceiling or floor return air grille for HVAC system that uses centralized air returns rather than room air-return ducts.
- Inside the air handler (in your attic or basement). There should be visible slot at the top or bottom of the unit (usually the bottom). Look for where the return air ducts connect to the blower fan and the removable cover should be nearby.

In order to clean your window AC unit (almost all of them contain a reusable filter), follow the directions below:
- Unplug the unit.
- Remove the front cover (may require unscrewing some screws).
- Once removed, you should be able to see the filter. Remove it (again, you may need a screwdriver).
- Instead of replacing the filter, clean it (make sure it is a reusable filter).
- To clean your air filter, take it outside and shake out any large pieces of dust and debris. Next, take your garden hose and rinse it thoroughly with soap and water.
- Only after the air filter completely dries can you put it back into place.
- After reinstalling the filter, screw the cover back on and plug in turn on your unit.
How to tell if your filter needs cleaning or replacing:
Every 30 days, check your air filter. You can tell if it needs to be cleaned or replaced by removing the air filter and holding it up to the light. If you can’t see any light pass through the filter, that means it is clogged and needs to be replaced. If light can pass through the filter, check your filter again in 15 days.
Simply replacing your air filter when it’s due can end up saving you up to 15% off of your cooling expenses.
Homes with large households, pets, or excessive dust and debris may require more frequent air filter replacements.
2. Evaporator Coils
Two coil systems are used to help cool your home: evaporator coils and condenser coils. For proper operation, they should be cleaned every year by a professional, however, frequent air filter cleanings or replacements can help keep them clean.
Evaporator coils are located inside the indoor air handler (in your basement or attic). When they get dirty, condensation drips down from the coils, carrying with it any dust or dirt from the coils. This dirty water ends up in your drain pan and eventually into your condensate drain line. When the evaporator coils are dirty, there is a much higher risk of your condensate drain line becoming clogged. Clogged condensate drain lines can cause leaks in your home, leading to costly water damage.
Evaporator coils also need to remain clean in or to absorb heat. if there is a layer of dust and debris, it won’t be able to absorb heat, leading to the common occurrence of frozen evaporator coils. Over months and years, your evaporator coils can become quite dirty. Make sure evaporator coil cleanings are included in your yearly air conditioning maintenance appointment.

3. Condenser Coils
The other coil system at work for your HVAC system is located in your outdoor condenser unit. Condenser coils can get dirty and clogged from grass clippins, twigs, dirt, and other debris. In order to keep your HVAC system operating efficiently, you will want to periodically inspect your outdoor unit and clean it every 1-2 months.
In order to keep your outdoor condenser unit clean, there are a few things you can do (or not do):
- Keep plants and foliage away from the unit. Although it is tempting to hide your unsightly HVAC unit, it needs a minimum clearance of 2 feet in order to receive the proper airflow for your cooling system to work.
- Consider xeriscaping around your outdoor HVAC unit to reduce the amount of grass and other organic material from clogging up your system.
- Remove plants, leaves, twigs, and other debris from your unit every month. After a heavy storm, go outside to inspect your unit.
- Never stack anything on top of your outdoor HVAC unit.
- Keep a minimum clearance of 2 feet around your entire heat pump unit.

4. Window Air Conditioning Seals
Check your window air conditioning units for proper sealing around the window. If the seal is broken or compromised, you will want to make sure the unit and the window frame are properly sealed. Otherwise, moisture can damage the window unit and cool air can escape.
You will also want to inspect ALL of your doors and windows for proper air sealing. Read this home air sealing guide to learn how to properly air seal your home. Improving the insulation around your home can save you hundreds of dollars every year.
Cheap materials, such as caulk and masting tape will pay for themselves in the very first month.
