4 HVAC Maintenance Checklist Items for Louisiana Homeowners in 2025

The health of your HVAC system is the key to keeping your home at the perfect temperature year-round. Your system needs regular maintenance to ensure that it works effectively and efficiently.

While it’s important to schedule regular professional tune-ups, there are also steps you can take as a homeowner to reduce your risk of a breakdown and keep your system functioning at its best. Here’s our HVAC maintenance checklist to keep things running smoothly all year.

1. Change Your Air Filter

One of the simplest ways to ensure that your HVAC system works optimally is to change your air filters every three to six months. The filter is your system’s defense against debris, dirt, and allergens in your home; a clean filter means improved air quality and greater efficiency.

The type of filter you use can greatly affect your system’s performance. New high-efficiency pleated filters use an electrostatic charge to remove even the smallest particles that can be home to bacteria and microorganisms.

Regularly replacing your filters can increase your system’s efficiency, lengthen its lifespan, and improve indoor air quality.  

2. Remove Debris From Your Outdoor Unit

It’s important to check the surroundings of your outdoor unit. While it may be out of sight, out of mind, growth and debris can negatively affect your HVAC system’s performance.

You should regularly inspect the outdoor unit to ensure that weeds, yard debris, and garbage don’t inhibit air circulation.

Cleaning and removing growth from around the unit can reduce the risk of equipment damage and allow your HVAC to run at maximum efficiency.

3. Check Refrigerant Lines

In the summer, your air conditioner relies on refrigerant lines to create the cool air needed to ensure that your home stays comfortable. One of the most common HVAC issues is leaks in these lines.

You should regularly inspect these lines for any detachment or leaks that require professional repair. It’s critical to do these inspections every few months; catching a minor issue early means a technician can fix it before it becomes a major or costly problem.

4. Schedule Professional HVAC Maintenance

While you can handle minor HVAC maintenance needs, some system components are complex and require service from a professional. That’s why, in addition to performing the tasks above regularly, annual professional HVAC maintenance is key to ensuring your system’s longevity.

During these tune-ups, a technician will check electrical connections, make blower adjustments, measure coolant levels, and inspect fuel lines.

Why HVAC Maintenance Matters

Skipping HVAC maintenance can lead to major issues. For example, if you don’t change your air filter, airflow becomes restricted, which forces the system to work harder and may cause it to overheat or fail. Simple tasks like filter changes or coil cleaning help prevent breakdowns, high energy bills, and expensive repairs — especially in Louisiana’s harsh climate.
