Essential AC Maintenance Tasks

Regular maintenance of your air conditioning system is crucial for its longevity and efficiency. While professional checkups are recommended twice a year, there are several maintenance tasks you can perform yourself, along with periodic professional services. Here are some key maintenance tips to keep your air conditioning unit in top shape:

Thermostat Maintenance

Your thermostat acts as the command center for your HVAC system, signaling the air conditioner to turn on and off as needed. Most thermostats are powered by your home’s electricity, though some rely on batteries. To ensure proper functionality, replace the batteries annually or whenever a low battery notification appears.

Inspect the prongs on the back of the thermostat face to ensure they are not bent, broken, or missing. If any prongs are damaged, replace the thermostat to maintain optimal AC performance.

Coil Cleaning

Your air conditioner relies on two types of coils: the condenser coil and the evaporator coil. The indoor evaporator coil removes heat and moisture from your home, while the outdoor condenser coil cools the refrigerant before it returns to the evaporator coil. Dirty coils reduce system efficiency, so it’s advisable to clean them annually.

Coil cleaning is a relatively simple task, but if you’re uncomfortable doing it yourself, consider hiring an HVAC professional. Clean coils ensure your system runs smoothly and efficiently.

Ductwork Cleaning

Many homes have never had their ductwork cleaned, especially older homes with original ducts. Over time, dust and debris accumulate in the vents, which can be blown into your living space, potentially causing allergies and spreading viruses and bacteria.

Regular duct cleaning is essential for maintaining a healthy indoor environment. HVAC companies use EPA-approved cleaners to sanitize ducts, removing dust, debris, and allergens.

Air Filters

Changing your AC filters regularly is vital for system efficiency. Dirty filters restrict airflow, forcing the air conditioner to work harder. Filters prevent particles from entering the air handler, but over time, they become clogged with pollen, dander, and other pollutants, reducing system efficiency and potentially causing breakdowns.

Replace your air filters every 1-3 months, depending on usage and the type of filter.

Cleaning the Drain Line

Your air conditioner has a condensate pan that collects water from condensation. This water is then directed outside through a drain pipe. A clogged drain line can cause water to overflow into your home, potentially damaging drywall, insulation, and wood.

During the summer months, when your air conditioner produces more condensation, check the drain line regularly to ensure it’s clear. This simple task can prevent significant water damage.

DIY Maintenance Tips

While professional servicing is essential, there are several maintenance tasks homeowners can perform to keep their AC unit in good shape between professional checks:

Regularly Clean or Replace Filters: Depending on the type of filter, it should be cleaned or replaced every 1-3 months. This ensures efficient airflow and reduces the burden on the AC unit.

Keep the Outdoor Unit Clean: Ensure the outdoor condenser unit is free from debris, leaves, and dirt. This can improve efficiency and prevent overheating.

Check Thermostat Settings: Make sure your thermostat is functioning correctly and is set to an optimal temperature for cooling efficiency.

Inspect Ducts and Vents: Regularly check ducts and vents for any blockages or leaks. Proper airflow is essential for effective cooling.

When to Call a Professional

Despite your best efforts, some issues are best handled by professionals. If you notice unusual noises, poor cooling performance, or higher-than-normal energy bills, it’s time to call a technician. They have the expertise to diagnose and fix complex problems that DIY maintenance cannot address.
