Winter AC Maintenance Tips

As you already know, your HVAC unit requires year-round preventive maintenance to keep it running efficiently. Although winters in Florida tend to be mild, it’s important to be prepared for anything nature sends your way.

Routine AC maintenance helps homeowners in reviewing their property and making any necessary adjustments. Dealing with a damaged AC unit during winter is the last thing you want to deal with. To help you, we’ve come up with a list of preventive HVAC maintenance tips to help you prepare your AC for the cooler months.

10 Winter AC Maintenance Tips

While some preventive maintenance requires an HVAC professional, there are a few things you can easily do yourself that will ensure the longevity of your system.

1. Turn Off Power to Air Conditioner Before Performing Any Maintenance

This is an important step. Turning off the AC prevents the risk of being electrocuted while performing maintenance. To do this, locate the exterior power circuit. It looks like a small box and is mounted to the side of your home. Next, flip the switch to “Off” and close the lid.

2. Clean the AC Unit

Sweep off leaves, twigs, and other debris that are on and surrounding the AC. Pay careful attention to materials nearest to your cooling system’s condenser unit. Next, use a hose to rinse off dirt and dust. Allow the unit to dry. This will prevent clogging and malfunctioning that can otherwise occur in the later spring and summer months

3. Inspect the AC Unit

Watch out for rust, cracks, leaks, and other abnormalities that may have developed in the casing. Ensure seals are tight and not cracked. These things may seem minor but they can cause big problems later on. If any of these issues are found during your ac maintenance, contact us and we will send out one of our HVAC professionals.

4. Cover the AC Unit

Covering your air conditioner insulates it and protects it from any potential damage caused by debris. For optimal ventilation, make sure the fit is secure but not too tight. You will want to choose a waterproof vinyl or plastic cover that is made specifically for air conditioners. You can easily find these at any home improvement store.

You can also secure a waterproof tarp around the unit with ropes or bungee cords. Another method is to rest a sheet of plywood cut to fit the top of the unit plus an additional two feet of overhang on all sides, secured with a heavy brick.

5. Add Extra Insulation

To prevent cracking, cover your AC unit’s exposed pipes and wiring with foam pipe covers. Secure the foam insulation with duct tape. Adding extra insulation will prevent the wires and fluid in the pipes from freezing. Evaluate your attic for roofing problems and potential issues with your home’s insulation.

6. Listen to the Compressor

When the AC is running, listen for any strange noises like grinding, clunking or buzzing. If you hear any of these noises, your AC should be inspected by an HVAC professional.

7. Change AC Filter Monthly

During the cooler months, you’re using the heat a lot more often. To prevent clogging and poor air quality, we recommend changing the filter out every month. If you need assistance, we are happy to help with the replacement and recommend the type of filter that works best for your home’s HVAC system.

8. Check AC Regularly

Throughout the winter months, keep up with your preventive HVAC maintenance. Sweep away leaves, twigs, and other debris that collect on the unit. Remove water, frost, or ice that accumulates on the AC’s cover to prevent potential damage.

9. Update Your Programmable Thermostat

Reprogram your thermostat each season so you save energy while you are asleep or away from home.

10. Check Ductwork

Check your ducts and vents for obstructions, dirt, and possible leaks.
