Frequently Asked Questions

  • Some of the work during an AC tune-up includes a basic AC maintenance checklist:

    • Tightening electrical connections. This ensures your system is operating safely.
    • Lubricating parts. When your system isn’t lubed, rubbing from moving parts can cause it to malfunction more frequently.
    • Cleaning the condensate drain line. Cleaning this line takes care of mold and clogs, which can cause leaks.
    • Cleaning the condenser coil and evaporator coil. These coils become dirty gradually, reducing airflow and its ability to absorb heat.
    • Straightening coil fins. Aluminum fins on the coils can bend and decrease airflow.
    • Examining system controls. This makes sure your system is starting, running and shutting down properly.
  • There are usually various kinds of maintenance plans and rates. Check out our memberships page to learn about our tiered maintenance memberships.

  • Routine air conditioner maintenance is essential to keeping your equipment operating efficiently, and it can decrease the need for unanticipated replacements.

  • Some key factors will tell you that you need AC maintenance service on your unit, such as if your home has poor airflow or hot and cold spots, leaks, unusual noises or warm air coming from the vents.

  • Check this full guide to AC maintenance for various things you can do. One of the main things homeowners can do to help upkeep their system, other than having annual yearly or seasonal maintenance done, is to change your AC unit’s air filter every 60-90 days, or 30 days if you have family pets. Changing your filter on a routine basis can prolong the life span of your system by reducing wear and tear on the unit, preventing clogs and improving airflow. Using a higher quality HEPA filter can also help maintain the AC unit’s efficiency and reduce instances of sickness in your home.
