• Inspecting Electrical Components: Regularly checking the electrical connections and components for wear can prevent system failures. Faulty wiring or connections can pose safety hazards and lead to expensive repairs if not addressed promptly.
• Checking Refrigerant Levels: Ensuring the refrigerant is at the correct level is essential for the cooling process. Low refrigerant levels can indicate a leak, which needs to be repaired to maintain system efficiency and prevent compressor failure.

How Often Should Air Filters Be Replaced?

Air filter replacement frequency can vary based on several factors, including usage and type of filter.

• Standard Fiberglass Filters: These filters should typically be replaced every 30 days, as they are less effective at trapping dust and allergens compared to higher-quality options. Their lower cost means they are often used in residential settings, but they require frequent changes to maintain optimal air quality and system efficiency.
• Pleated Filters: Pleated filters are more efficient and can last up to 90 days before needing replacement. They have a larger surface area and can capture smaller particles, making them a better choice for those with allergies or asthma, and they help to reduce strain on the HVAC system.
• HEPA Filters: High-Efficiency Particulate Air (HEPA) filters are designed to trap up to 99.97% of particles and should be replaced every 6 to 12 months. They are ideal for individuals who want superior air quality and are particularly beneficial for homes with pets or smokers.
• Washable Filters: These filters can be cleaned and reused, usually requiring washing every 1 to 3 months depending on usage. While they can save money in the long run, they still need to be maintained properly to ensure that they do not become clogged and ineffective.
• Environmental Factors: If you live in an area with high levels of dust, pollen, or pollution, you may need to change your air filters more frequently. Seasonal changes can also impact how often filters should be replaced, as increased usage during summer or winter months can lead to quicker buildup of debris.

What Key Components Should Be Inspected During Maintenance?

During AC maintenance, several key components should be inspected to ensure optimal performance and efficiency.

• Air Filters: Regularly checking and replacing air filters is crucial as they trap dust, dirt, and allergens, preventing them from circulating in your home. Clogged filters can restrict airflow, making the system work harder and potentially leading to breakdowns.
