Signs That Your Air Conditioner Needs a Tune-Up

Annual maintenance is essential for keeping your air conditioner in prime condition. While it’s not uncommon to let maintenance lapse, you will want to get back on track as soon as possible to protect your system from damage and to preserve the energy-efficient operation of your cooling system. In fact, most homeowners easily recoup their investment in preventative AC maintenance thanks to the long-term energy savings, smaller repair bills, and longer service life. It will also help improve indoor air quality.

In this blog, we’ll cover the common signs that indicate a tune-up is due. If you notice any of the following signs, we recommend scheduling AC maintenance without delay. 

Signs Your AC Needs a Tune-Up

1. Warm Air Blowing

Warm air blowing through your vents can indicate low refrigerant levels that are often the result of leaks in the system. It can also occur when evaporator coils become dirty because the dirt/debris inhibits the flow of air over the coils. Another common cause is because of a malfunctioning thermostat. 

2. Diminished Airflow

Diminished airflow through registers can indicate blocked or leaky ductwork or possibly a clogged filter. If it’s a longstanding issue, it’s possible that the unit is undersized or oversized for your home or due to a faulty thermostat.

3. Significant Temperature Differences Between Rooms

There are many possible causes if some rooms in your home get chilly while others remain toasty. If heat gain through windows or seals around doors and windows are intact, then it’s possible that your fan motor isn’t working properly or that you have a blockage within that particular section of ductwork.

4. Odd Sounds

Buzzing, grinding, clanking, or banging are alarm bells you shouldn’t ignore. They can indicate loose components, missing components, refrigerant leaks, or broken isolation feet. These issues require prompt attention; otherwise, your system can incur significant, potentially irreparable damage.

5. Increased Humidity or Water Leaks

Increased indoor humidity and any water leaks can cause mold and mildew to proliferate. These issues are typically caused by a leaking compressor or a clogged drain tube.
