When the summer heat rolls in, there’s nothing more frustrating—or more expensive—than a malfunctioning air conditioner. The best way to avoid unexpected breakdowns and high energy bills? Routine AC maintenance.

At Prime Home HVAC, we believe that a well-maintained AC unit not only keeps your home cool and comfortable but also helps extend the life of your system and reduce monthly energy costs. Whether you’re a new homeowner or a seasoned DIYer, this AC maintenance checklist will help you keep your cooling system running smoothly all season long.

✅ 1. Replace or Clean the Air Filter

One of the simplest yet most important steps in AC maintenance is checking your air filter. A clogged or dirty filter restricts airflow, causing your system to work harder—and use more energy.

  • Recommended frequency: Every 30–90 days
  • Pro tip: If you have pets or allergies, replace it monthly.

✅ 2. Check and Clean the Outdoor Unit (Condenser)

Your outdoor condenser unit plays a critical role in cooling your home. Over time, debris like leaves, grass clippings, and dirt can collect around it and reduce efficiency.

  • Steps to follow:
    • Turn off power to the unit
    • Remove debris around the base
    • Gently clean the fins with a garden hose (never a pressure washer!)
    • Make sure there’s at least 2 feet of clearance around the unit

✅ 3. Inspect the Thermostat

Make sure your thermostat is working properly and accurately maintaining the temperature you set.

  • Upgrade tip: Consider switching to a programmable or smart thermostat to maximize efficiency and automate cooling based on your schedule.

✅ 4. Clean the Evaporator Coils

Located inside your home, evaporator coils absorb heat and help cool your air. Dust and grime buildup can impair their performance over time.

  • DIY or Pro? Light cleaning can be done at home, but a thorough cleaning is best left to professionals during an annual tune-up.

✅ 5. Check the Refrigerant Lines

Refrigerant lines carry coolant between your indoor and outdoor units. If they’re leaking or improperly insulated, your system won’t cool efficiently.

  • Warning signs of a problem:
    • Hissing noises
    • Ice on the lines
    • Inconsistent cooling

✅ 6. Clear the Condensate Drain Line

This small pipe drains excess moisture from your AC. If it gets clogged, it can lead to water damage or mold inside your home.

  • Simple fix: Pour a mixture of vinegar and water into the drain line every few months to help prevent blockages.

✅ 7. Listen for Unusual Sounds

Grinding, squealing, or rattling noises aren’t normal—and they’re often the first sign that something is wrong.

  • What to do: Turn off the system and call a professional HVAC technician to inspect it before more damage occurs.

✅ 8. Schedule a Professional AC Tune-Up

While homeowners can do a lot, there’s no substitute for a trained technician. A professional AC maintenance visit from a company like Prime Home HVAC includes:

  • Refrigerant level check
  • Full electrical system inspection
  • Thermostat calibration
  • Coil and component cleaning
  • Airflow testing
  • Mechanical part lubrication
