AC Maintenance Guide

Preventative AC maintenance is an invaluable investment of your time and money. A well-maintained air conditioning system will operate more efficiently and reliably. Plus, staying on top of maintenance will extend your system’s serviceable life span, which reduces your long-term repair and replacement costs. At ABC Plumbing, Sewer, Heating, Cooling and Electric, our NATE-certified HVAC technicians are happy to answer your questions and perform the preventative cooling maintenance your system requires.

What gets checked during AC maintenance?

A proper AC maintenance inspection is comprehensive. Our AC technicians have a list of components and functions we inspect that includes:

  • Checking refrigerant levels
  • Inspecting for refrigerant leaks
  • Cleaning the condenser coils (and straightening as needed)
  • Cleaning the evaporator coil and drain
  • Clearing debris and obstructions from around the air conditioner
  • Cleaning the condenser fans and testing for smooth operation
  • Inspecting and testing electrical components
  • Changing the blower filter

How often should AC be tuned up?

It would be best to tune up your air conditioner at least once per year, ideally, twice. Doing it twice can significantly reduce problems and keep your air conditioner in prime condition.

When is the best time of the year to tune up an AC?

We recommend scheduling an air conditioner tune-up in the spring and the fall. This ensures the system is ready to perform as required during the hotter summer months, and it allows our technicians to correct any defects and damage at the end of the cooling season before the leaves start to fall.

How long does AC maintenance take?

It depends on the air conditioner, but most systems take one to two hours to properly service. If components need to be replaced, the appointment may take longer. Our NATE-certified technicians in Chicago will give you a reliable estimate based on your specific system and needs.

Should I maintain an older air conditioner?

It is worth keeping your air conditioner operational for as long as possible. However, there is a point at which maintenance and repairs stop being effective and become more costly. This includes when repair frequency increases or any repair exceeds more than 50% of the replacement cost or if you have an older system nearing the end of its expected operational life span. We can help you identify a suitable replacement that will offer the reliability and energy efficiency you desire. We even offer financing to make replacing your air conditioner easier and more affordable when the time comes.
