If you want your air conditioner to keep you cool during Bellingham’s warmer months, regular maintenance isn’t just a good idea—it’s essential. Just like your car needs oil changes and tire rotations, your air conditioning system needs periodic attention to run at peak performance. At Lynden Sheet Metal Inc., we’ve been helping homeowners across Whatcom County extend the life of their HVAC systems with expert maintenance services for decades.
In this blog, we’ll break down the key tasks involved in regular AC maintenance, why they matter, and how our team can help you stay ahead of costly repairs and breakdowns.
Why Air Conditioner Maintenance Matters
Routine maintenance does more than keep your AC running—it helps lower your energy bills, improves indoor air quality, and prevents surprise breakdowns in the middle of a heatwave. Skipping tune-ups might not cause issues right away, but over time, dirt buildup, loose connections, and wear and tear can reduce efficiency and shorten your system’s lifespan.
What Should Be Done During a Maintenance Visit?
Here are the most important maintenance steps that should be done regularly—ideally once a year before peak cooling season begins:
Clean or Replace Air Filters
Dirty filters are one of the most common causes of AC problems. Clogged filters restrict airflow, making your system work harder and increasing energy usage. We recommend checking filters monthly and replacing them every 1–3 months depending on usage and household needs.
Inspect and Clean the Coils
Over time, your evaporator and condenser coils collect dirt, reducing the system’s ability to absorb and release heat. During a maintenance visit, our technicians carefully clean these coils to ensure optimal performance.
Check and Clear the Condensate Drain
Blocked condensate lines can cause water leaks and even lead to mold or water damage. We inspect the drain to ensure it’s flowing freely and clear any blockages if needed.
Test System Controls and Thermostat
We’ll check that your thermostat is calibrated correctly and confirm that your system cycles on and off properly. This helps ensure your system is maintaining the desired temperature without short cycling.
Inspect Electrical Components and Tighten Connections
Loose electrical connections are a safety hazard and can lead to system failure. Our team inspects wires, capacitors, contactors, and relays to catch any issues early.
Lubricate Moving Parts
Your AC system has motors, fans, and other components that benefit from regular lubrication. This helps reduce friction, prevent overheating, and extend the life of these parts.
Measure Refrigerant Levels
Improper refrigerant charge—either too much or too little—can cause inefficiency or even damage your compressor. We’ll check refrigerant levels and diagnose any leaks.
Examine Ductwork and Airflow
If airflow feels weak or uneven, it could point to duct leaks or obstructions. Our technicians can assess your system’s airflow to ensure it’s balanced and efficient.
