1. Clean or Replace Your Air Filter Regularly
One of the simplest yet most essential steps for maintaining your air conditioner is keeping the air filter clean. Over time, your filter collects dust, dirt, and other airborne particles. If it gets clogged, your system has to work harder to pull air through, which reduces efficiency and can even lead to breakdowns.
👉 Why it matters: A dirty filter can restrict airflow, increase energy use, and cause uneven cooling in your home.
👉 How often: Check your filter every 1-2 months during peak use. If it’s dirty, replace or clean it as needed.
👉 Tip: High-efficiency pleated filters are great for homes with pets or allergies, capturing more particles and keeping your indoor air cleaner.
2. Clear Debris Around the Outdoor Unit
Your air conditioner’s outdoor condenser unit needs clear airflow to function properly. Unfortunately, leaves, grass clippings, dirt, and other debris can build up around it. If these obstructions block the coils or fan, your system has to work overtime to push out heat, leading to higher energy bills and possible overheating.
What to do:
Keep at least 2-3 feet of clear space around the unit.
Remove any leaves, sticks, or yard debris regularly.
Use a gentle spray from a hose (not a pressure washer!) to rinse off dirt from the coils.
Thanks to Mitsubishi’s advanced inverter technology, mini splits adjust their compressor speed to maintain consistent indoor temperatures. This not only enhances comfort but also reduces energy consumption compared to conventional HVAC systems that cycle on and off.
3. Check Your Thermostat Settings
It might sound obvious, but sometimes your thermostat might be set to “fan” instead of “cool,” or it’s not adjusted to the temperature you want. A properly set thermostat ensures your AC cycles efficiently and maintains your desired comfort level.
What to do:
Double-check that your thermostat is on “cool” mode.
Set it to your preferred temperature—usually around 72-75°F for comfort and efficiency.
Consider upgrading to a programmable or smart thermostat. These can adjust temperatures based on your schedule, reducing energy use and lowering your bills.
4. Seal Any Leaks in Windows or Doors
Cool air can easily escape through gaps in windows, doors, and ductwork. If your home isn’t well-sealed, your AC has to work harder to keep things cool, which drives up your utility bills and wears out your system faster.
👉 How to seal up your home:
Check for drafts around doors and windows. Use weatherstripping or caulk to seal gaps.
Consider adding door sweeps to the bottom of exterior doors.
In older homes, add insulation to your attic or walls to improve overall energy efficiency.
5. Schedule Professional AC Maintenance
Even with the best DIY maintenance, your air conditioner needs a professional tune-up at least once a year. Professional technicians (like us at Lynnwood Heating!) can catch problems you might not notice, clean components you can’t reach, and ensure your system runs at peak performance.
What to expect in a professional AC maintenance visit:
Checking refrigerant levels and pressures.
Inspecting and cleaning the evaporator and condenser coils.
Testing electrical connections and controls.
Ensuring your thermostat is calibrated correctly.
Checking the condensate drain to prevent clogs and leaks.
Regular maintenance can help you avoid expensive repairs down the road and extend the lifespan of your unit.
Why Maintenance Matters
When you’re dealing with Washington’s summer heat, a well-maintained air conditioner isn’t just a luxury—it’s a necessity! Here’s why:
Improved energy efficiency – Lower your cooling bills by up to 15% with regular maintenance.
Better indoor air quality – Cleaner filters and coils mean cleaner air in your home.
Fewer breakdowns – Address small issues before they turn into costly repairs.
Longer lifespan – A maintained AC unit can last years longer than a neglected one.
When to Call the Pros
While these tips can help keep your AC in good shape, sometimes you need expert help. If you notice:
Unusual noises (banging, grinding, or buzzing sounds).
Warm air blowing from vents.
Ice forming on the outdoor unit.
Rising energy bills despite normal use.
