DIY HVAC Maintenance Tips for Homeowners

Did you know that your HVAC system might not be working as efficiently as it should be? HVAC units typically become inefficient over time, which can lead to your system needing significant repairs or increasing energy bills.

AC preventative maintenance will ensure that your family and home remain comfortable, but it can also help you save money in the long run. Here are seven DIY HVAC maintenance tips to keep your air conditioning unit working at full force:

Understand Your AC

AC preventative maintenance starts with familiarizing yourself with your AC unit. Most central air conditioners have indoor and outdoor units. If you have a furnace, the indoor unit sits in a central duct near the furnace. However, if you have a heat pump, the indoor unit will be in the air handler.

Once you are familiar with your HVAC system, you should read through the manuals provided by the manufacturer. Make a note of every unit's maintenance periods. These maintenance periods have been tested by the manufacturer and determined to be the ideal time to schedule your AC preventative maintenance. Ignoring the maintenance on many units can invalidate the warranty, so please be sure to perform all required tune-ups.

Inspect Your Thermostat

A simple DIY maintenance step is to inspect and maintain your thermostat. For many HVAC systems, the thermostat is an essential part of the unit's functions.

If your thermostat runs on batteries, check the life of the batteries. Thermostat batteries can usually last up to two years.

Clean Your HVAC External Unit

  • Clean Condenser Unit Fan: Dust, debris, and leaves can clog the condenser fan. To remove debris, wipe down the condenser fan with a damp cloth and let it dry naturally.

  • Clean Around the Unit: Remove any debris around the condenser fins with an old paintbrush. Also, make sure the area around the condenser is separated from plant growth and other outdoor objects by at least 2ft.

  • Fix & Vacuum Fins: Use a hose or fin spray to clean the fins. You may also need to straighten and realign damaged fins.

  • Check the Drain Pan: This ensures that nothing is obstructing the pan's flow.

Clean HVAC Internal Unit

The evaporator unit is an essential part of your air conditioning system since it heats and cools the inside of your home. You should clean evaporator coils regularly to prevent your HVAC unit from working less efficiently. Clean the coils with a soft brush to remove dust, then spray a coil cleaner to remove remaining debris.

It's also essential to clean the drain line to prevent any clogged drains and floods. Use a vacuum to clean algae and other debris from the drain.

Replace the Filter

Replacing your air filters is a great DIY HVAC maintenance measure that'll keep your system efficient. On average, you should change filters every one to three months. Be sure to note the correct size filter for your system. Trying to fit the wrong size filter into your HVAC system can reduce its efficiency and ultimately the life of the appliance.

Remove Blockages from Ducts

If you notice the vents in your home are dirty, remove the vent covers with a screwdriver and use soap and hot water to clean them thoroughly. This is a simple AC preventative maintenance tip, but clean vents will improve your AC's energy efficiency and prevent blockages from forming in your air ducts. We recommend that you have your air ducts cleaned at least every 5 years. It helps your HVAC system run better and reduces allergens native to Atlanta, dust, and particulate in the air you breathe.

Schedule Maintenance Inspections

It's worth noting that more complex repairs may be necessary beyond DIY HVAC maintenance. Sometimes, a professional is needed to help with emergency repairs that can be dangerous.
