What to Expect from an AC Tune-Up

Many HVAC companies will say you need regular AC tune-ups, but what is actually taken care of during a tune-up and why are tune-ups so important? Besides the regular cleaning, inspecting, and replacing faulty parts throughout the entire unit, here’s what you can expect from a traditional AC tune-up.

Check thermostat

The health and settings of your thermostat are more important than you think. An improperly installed thermostat or thermostat with incorrect settings can force your AC unit to work harder, increase your monthly bill, and even shorten the lifespan of the unit. If you get a furnace or AC tune-up, the HVAC technician will check that your thermostat is correctly set to save you money in the long run.

Clean evaporator and condenser coils

Over time, dust and debris will collect on the evaporator and condenser coils. This will force your AC unit to work harder and eventually could cause a freeze-up. It is important these coils get cleaned regularly to keep your unit running efficiently.

Check coolant levels

The coolant—or refrigerant—runs through the interior coils in your air conditioner, absorbs the heat and cools the air. If the coolant is low, there is likely a leak which the tech will check for, but this also means your unit will not run efficiently and could freeze-up. Your AC unit needs the right amount of coolant to run correctly.

Inspect condensate line

Air conditioners tend to dehumidify the air, and that moisture builds up on the condenser coils. This water either evaporates or falls into the drip pan and is brought outside of the home through the condensate line. If this condensate line becomes clogged by dust or ice, this water stays in your unit and can cause a freeze-up, rust in the unit, and leak in your home.

Check blower motor and blower belt

During the heat of the season, your blower motor may run for many hours on end without rest. It is natural for this part—along with the blower belt—to eventually need replacing, but with proper maintenance from the HVAC technician during a tune-up, this part should last as long as the unit itself. Without the blower motor, the unit cannot function.
