Not only does regular HVAC maintenance help extend the life of your heating and cooling system, but it also ensures it operates efficiently to save you money on energy bills.


So what HVAC maintenance do you need to complete to make sure you don’t suffer unexpected breakdowns or less efficiency during extreme weather? We break down our top 10 HVAC maintenance tips to keep your unit running smoothly this summer. Avoid the heat wave and stay cool this summer.

Why Regular HVAC Maintenance Matters for Your Home

Regular maintenance of your HVAC system is crucial for home comfort. It helps to prevent costly repairs by catching issues early, so you’re never left waiting for an unexpected repair. And, a well-maintained HVAC system operates more efficiently, reducing your energy bills even when the weather spikes. Lastly, regular heating and cooling maintenance extends the lifespan of your HVAC system, ensuring you get the most out of your investment for longer.


So, don’t put off your HVAC maintenance this year. Although it may seem like your unit is running fine, you may be experiencing higher energy bills or increased usage without noticing. A few quick HVAC maintenance tips and you can improve your home comfort.

Tip 1: Regularly Change Your Home Air Filters

One of the simplest yet most effective ways to maintain your HVAC system is by regularly changing the air filters. Dirty filters restrict airflow, forcing your system to work harder and reduce its efficiency.


It’s recommended to change your HVAC air filters every 1-3 months, depending on the type of filter and your household conditions, such as pets or allergies. Keep a log near your unit recording when you last changed your air filters to keep up with regular maintenance.

Tip 2: Schedule Professional Inspections Annually

Scheduling regular professional HVAC inspections is vital to ensure your HVAC system remains in top condition. At ASC HVAC, we offer free estimates to help hone in on what could be affecting your HVAC unit and give you an honest quote on repairs.

It’s advisable to have your HVAC system inspected at least once a year, preferably in the spring or fall before the peak heating or cooling seasons.

Tip 3: Keep Your Outdoor Unit Clean for Best Results

Your HVAC system’s outdoor unit can accumulate debris such as leaves, dirt, and grass clippings year-round, which can obstruct airflow and reduce efficiency inside. Regularly check the outdoor unit and clean away any debris.


You want to check that there are at least two feet of clearance around the unit to promote proper airflow. Incorporate this into your spring cleaning and home winterization plan to prevent unexpected issues when you need your unit the most.

Tip 4: Check and Clean the Ductwork

Dirty or clogged air ducts can reduce your HVAC system’s efficiency and affect indoor air quality. You want to inspect your ductwork regularly for dust, mold, and other contaminants. You can clean minor dust buildup yourself, but for a thorough cleaning, it’s best to hire a professional duct cleaning service.


Plus, refreshed ductwork is the best time to invest in new indoor air quality air purifiers for your home, to help reduce allergens and other particles. The cleaner your air the better home comfort you will have and it helps with your HVAC unit’s operation.

Tip 5: Monitor Thermostat Settings Carefully

Your thermostat affects your HVAC system’s efficiency more than most homeowners realize. Keeping your thermostat set at optimal temperatures (78°F in the summer and 68°F in the winter) can help improve the efficiency and lifespan of the unit.


Consider investing in a programmable thermostat to automatically adjust the temperature when you’re away from home, further enhancing energy efficiency. There are also Smart thermostats that can be adjusted directly from your smartphone or that alter settings based on when you need heating and cooling the most.

Tip 6: Inspect and Clean the HVAC Coils

The evaporator and condenser coils in your HVAC system play an important role in heat exchange. Over time, these coils can become dirty and reduce efficiency. Inspect and clean the coils at least once a year. If the coils are heavily soiled, consider hiring a professional to clean them.


If you’re unsure how to inspect your HVAC coils, contact ASC HVAC in Howard County to help with maintenance and inspections this summer.

Tip 7: Ensure Proper Insulation in Your Home

Proper insulation in your home helps maintain the desired temperature, reducing the load on your HVAC system. Check your home’s insulation, particularly in the attic and walls, and add more if necessary.


Well-insulated homes retain heat in the winter and stay cool in the summer, enhancing HVAC efficiency. Check around windows, doors, siding, attics, and the basement. If you notice cracks, leaks, drafts, or moisture, you may need to adjust your insulation and sealing for better HVAC maintenance.

Tip 8: Clear and Maintain Drain Lines in Your HVAC

HVAC systems have drain lines that remove condensation. If these lines become clogged, it can lead to water damage and mold growth. This can disable your HVAC unit or dramatically lower its ability to operate properly.


Check the drain lines regularly as part of your HVAC maintenance and clear any blockages to ensure proper drainage. Using a mixture of vinegar and water can help keep the lines clean. Include this in your spring cleaning checklist each year for best efficiency.

Tip 9: Listen for Unusual Noises in Your HVAC Unit

Unusual noises from your HVAC system can indicate a problem. Listen for sounds like grinding, squealing, or banging. These noises could signify issues such as loose parts, worn-out belts, or motor problems. You may be heading towards an HVAC failure and will need HVAC repairs to keep your unit working.


If you hear any unusual noises, contact a professional technician to diagnose and fix the issue promptly. Free estimates on HVAC repairs can help you prepare and plan accordingly for any HVAC adjustments you will need.

Tip 10: Use Fans to Assist in Cooling and Temperature Control

Ceiling fans and box fans can help distribute air more evenly throughout your home, reducing the burden on your HVAC system. Even a low setting can rotate the air and distribute it throughout each room.


In the summer, set your ceiling fan to rotate counterclockwise to create a cooling breeze. In the winter, switch it to clockwise at a low speed to help circulate warm air. This will allow your climate control to be more even without cranking up the HVAC to compete against the weather. Plus, it helps with humidity in Maryland summers.
