A/C Maintenance in Farmington Hills, MI

Your A/C needs routine maintenance outside of maintenance, including:

• Air filter changes at the intervals recommended in the user manual.
• Cleaning coils on the outdoor unit.
• Clearing any debris on the outdoor unit, especially after storms.
• Cleaning condensate drains monthly.
• Dusting vents and registers.

You can often handle these tasks yourself.

Ideally, A/C systems should be serviced annually in the spring or summer. If you have a heat pump, it should receive a spring maintenance for cooling and an additional fall maintenance for heating.

You can do some aspects of the A/C maintenance yourself, as detailed in the question above, but others are best left to professionals. More specifically, you should have a professional:

• Check and adjust refrigerant levels.
• Perform an electrical inspection.
• Testing and calibrating the system’s performance.

Yes, annual A/C maintenance is a worthwhile investment if you want to extend the lifespan of your system and minimize repair costs. Annual professional maintenance is also often a requirement to keep manufacturers’ warranties valid.

• Warm airflow.
• Strange sounds, such as rattling, squealing, and grinding.
