Air Conditioning Unit Maintenance

Yes, a dirty air filter can cause your home AC system not to work. Your air conditioner is designed so that there must be sufficient airflow through the filter to cool properly.  Fortunately, this is the easiest problem to fix, and you can do it yourself.

It could cause your air conditioning system to stop working. It’s easy to forget to change your air conditioner filter.

If you do, you may experience:

• Poorer air quality
• Higher energy bills as your unit struggles
• Longer times for cooling

You may even have a full air conditioning breakdown on your hands, because the filter won’t catch the dust, and it can jam up the more delicate parts of your unit. Change your air filter on a regular basis and consider professional AC maintenance service for best results.

On average your should change your air filter every 1-3 months. But how often you need to change your AC filter depends on the kind of household you live in. You need to change it more frequently if you have pets or if anyone in your home suffers from allergies. Your filter affects your indoor air quality and also the efficiency of your air conditioner.

It’s better to err on the side of changing too often. Once every 30 days is a good frequency. Pair a filter change with expert maintenance, and your air conditioner will be in top shape.

Consider using HEPA filters if you have allergies or asthma. HEPA filters trap microscopic particles such as pollen, dust mites, pet dander, and mold spores, which improves indoor air quality and alleviates allergy symptoms. For best filtration, use HEPA filters with MERV ratings of 17-20. Regular filter replacement is required to maintain effectiveness and reduce allergy triggers in the home, resulting in cleaner air and improved respiratory health for allergy and asthma patients.

Air conditioner maintenance commonly involves several key tasks to ensure the system operates efficiently and extends its lifespan. Technicians typically replace or clean air filters to improve airflow and air quality. They check and clean the condenser and evaporator coils to prevent overheating and inefficiency. Inspecting and cleaning the drain line is crucial to prevent water leaks and mold growth. Technicians also check refrigerant levels, adding more if necessary, to ensure optimal cooling. Electrical connections are tightened, and moving parts are lubricated to reduce wear. Finally, they verify thermostat settings and system controls for proper operation. Regular maintenance helps prevent unexpected breakdowns and maintains energy efficiency.

Your air conditioner should undergo maintenance at least once a year, ideally in the spring before the cooling season begins. This annual service allows a professional to clean and inspect your system, ensuring it operates efficiently during the warmer months. If you live in a region with high usage demands or have a heat pump system that runs year-round, consider bi-annual maintenance, in the spring and fall, to maintain optimal performance and prolong the life of your unit. Regular maintenance can prevent costly repairs and reduce energy bills.

Signs that your AC needs maintenance include reduced airflow, unusual noises like banging or squealing, unpleasant odors, and frequent cycling on and off. Additionally, if you notice increased energy bills, uneven cooling throughout your home, or if the unit struggles to reach the set temperature, it's time for a check-up. Water leaks around the unit or frozen coils are also indicators. Regular maintenance can address these issues, ensuring efficient operation and prolonging the lifespan of your AC system.
