What Happens During An AC Tune-Up?

The temperature's rising, and summer's right around the corner. It's the perfect time to think about scheduling an AC tune-up. You've heard it's important, but what exactly does an AC tune-up entail? 

Inspection and Cleaning of the Condenser Coils

The tune-up process starts outside your home with the condenser unit. Your technician will inspect the condenser coils for any dirt or debris build-up. Clean condenser coils are essential as they dissipate the heat removed from your home more effectively. This step enhances the system's energy efficiency, so it's a crucial part of any AC tune-up.

Checking the Refrigerant Level

Next up, your HVAC professional will check the refrigerant levels. Having the correct amount of refrigerant ensures your AC is cooling effectively and efficiently. If the refrigerant levels are low, there might be a leak that needs fixing.

Inspecting and Tightening Electrical Connections

Over time, your AC's electrical connections can become loose due to vibration and regular use. As part of the AC tune-up, the technician will check and tighten these connections. Loose connections can not only reduce your system's efficiency but also become a safety hazard, making this a critical step in the process.

Checking the Thermostat

A properly functioning thermostat is key to maintaining your home's comfort. Your technician will ensure your thermostat is operating correctly and communicating properly with the AC unit. If you have an older mechanical thermostat, they might suggest upgrading to a programmable model for better energy efficiency.

Inspecting the Blower Motor and Belt

Your HVAC professional will also inspect the blower motor and belt. The blower motor is responsible for pushing the cooled air through the ductwork and into your home. If it's not functioning optimally, it can lead to decreased comfort and increased energy costs.

Cleaning or Replacing the Air Filter

Regularly cleaning or replacing the air filter is one of the simplest yet most important parts of maintaining your AC's efficiency. A clogged filter can lead to reduced air flow, forcing the system to work harder and increasing your energy costs. During a tune-up, your technician will either clean or replace the filter, depending on its condition.

Testing the System

After going through all the components, the technician will run the system to ensure everything is working properly. They'll look out for unusual noises or vibrations, check the system's starting capabilities, and measure the temperature difference between the air coming into the AC and the cooled air going into your home.

Your AC's Annual Health Check

Think of an AC tune-up as a health check for your air conditioner. It ensures your system is ready to keep you cool during the scorching summer months. Regular tune-ups can also catch potential issues before they turn into costly repairs or cause a system breakdown at the worst possible time—like in the middle of a heatwave.
