Common AC Problems & What to Do About Them

Air conditioners work hard to keep your home cool, but like any system, they can develop issues. Some problems are minor and can be fixed with simple troubleshooting, while others require professional attention. Understanding what can go wrong and when to call for help can save you from unexpected breakdowns and costly repairs.

What Can Go Wrong with an AC System?

Several issues can affect the performance of your AC unit, leading to inefficient cooling, higher energy bills, or complete system failure. 

Some of the most common AC problems include the following:

• Refrigerant Leaks – Low refrigerant levels often indicate a leak, causing your system to struggle to cool appropriately. A technician must locate and repair the leak before recharging the system.
• Clogged or Dirty Filters – A dirty air filter restricts airflow, forcing your AC to work harder and reducing efficiency. Regularly replacing or cleaning filters can prevent this issue.
• Frozen Evaporator Coils – When airflow is restricted or refrigerant levels are low, evaporator coils can freeze, stopping your AC from cooling. Thawing the coils and addressing the root cause can restore proper function.
• Thermostat Malfunctions – If your AC isn’t turning on or maintaining the right temperature, the thermostat may need calibration, new batteries, or a complete replacement.
• Electrical Component Failures – Faulty wiring, failing capacitors, or worn-out motors can cause your system to short cycle or stop working altogether. A professional should always handle these issues.

Ignoring minor problems can lead to more significant, more expensive repairs. Calling a professional is essential. We diagnose AC issues quickly and provide honest, straightforward solutions to restore your system.

To avoid these issues, we recommend scheduling regular maintenance checks with us. During these checks, we thoroughly inspect all components, ensuring every part of your system is in optimal condition.

FAQs About Air Conditioning in Salem, Oregon

What is the life expectancy of a central air conditioner? 

Most central air conditioning units have a typical life expectancy of 10 to 15 years. The two main factors that extend this life are ensuring the unit is properly sized upon installation and committing to annual professional maintenance, ideally performed every spring.

How often should I have my AC serviced? 

We highly recommend scheduling a professional AC tune-up once every year, preferably before the start of the cooling season in the spring. This preventative service ensures the system is clean, calibrated, and helps identify minor issues before they lead to an expensive summer breakdown.

What size AC unit do I need for my home? 

Determining the correct size is a complex process that goes beyond just square footage. Our licensed technicians perform a detailed load calculation, taking into account factors like your home’s insulation, window placement, and local climate to ensure the unit is perfectly sized for maximum efficiency.

Why is my AC running constantly (short cycling or long cycles)? 

If the AC is short cycling (turning on and off frequently), it may be oversized or have a major electrical fault. If it runs for very long cycles but struggles to reach the set temperature, it may be undersized or suffering from a refrigerant leak or severe airflow obstruction.
