Signs Your AC System Needs Expert Repair

Some of the most common indicators that signal it is time to call in a professional include:

  • Short cycling
  • Hot air coming from vents
  • High indoor humidity
  • Foul odors
  • Water leaks
  • AC thermostat fails to work
  • Ice accumulation on the unit
  • Odd noises
  • Unusually high energy bills
  • Warm spots on your property

Short Cycling

Short cycling is when an AC unit turns on and off repeatedly without running a full cooling cycle. This is often caused by an improper thermostat setting, a dirty air filter, or insufficient refrigerant levels. It may also be the result of a poorly sized AC unit. A unit that is too large for the space it’s intended to cool will keep running until it has achieved the desired temperature and then shut off before completing a full cycle. If you notice your AC unit is short cycling, call an HVAC technician to diagnose and repair the issue properly. Short cycling can be very harmful to your air conditioning system.

Hot Air Coming From Vents

If you detect unusually warm air coming from the vents in your home, it’s likely that your system is either low on refrigerant or the compressor isn’t working properly. Either way, this is a sign that you need to call a professional. Refrigerant levels should never fall below the manufacturer’s recommendation and need to be handled by an experienced technician.

High Indoor Humidity

An AC unit’s job is to not only cool the air but also reduce humidity levels inside your home. Therefore, high indoor humidity could be an indication of a malfunctioning air conditioning system. If you notice that your indoor humidity is unusually high, it may be a sign of a faulty evaporator coil or leaky ducts.

Foul Odors

If your AC system is emitting strange or foul odors, it could be a sign of mold or mildew buildup in the unit or in the ductwork that needs to be cleaned and sanitized as soon as possible. It could also occur as a result of a burnt wire.

Water Leaks

Leaky air conditioners are a common issue, but if not addressed in a timely manner it can cause serious damage to your home. Make sure to check for standing water and have any leaks fixed as soon as possible by a professional technician.

AC Thermostat Fails To Work

Your unit’s thermostat is responsible for controlling the flow of cold air and could be the source of many issues. If your thermostat fails to work or it’s not accurate, your AC may not turn on or it may go off after a short time. If your AC thermostat fails to work correctly, it could be the result of an electrical short, faulty wiring, or incorrect programming. Have it checked and repaired by a professional to ensure accuracy.

Ice Accumulation on The Unit

If you notice ice accumulating on your AC unit, it could indicate an issue with the refrigerant levels or condenser coil. Make sure to have it inspected and repaired as soon as possible.

Odd Noises

If your AC system is making noises such as clanging, hissing, or rattling, it could be a sign of a belt issue or dirty internal components that need to be professionally cleaned and serviced.

Unusually High Energy Bills

If you’ve been noticing higher than usual energy bills each month, it could be a sign of an AC system that is not running efficiently. Have it inspected and serviced by a professional to determine what may be causing the issue.

Warm Spots on Your Property

Sometimes a problem with the AC system can cause warm spots on your property. This is not a ghost problem. It may be due to an issue with the AC or the ductwork and needs to be looked at right away by a professional technician. If your unit is new, it may be too small for your home and needs to be replaced.


The warning signs of an air conditioner in need of repair can vary from obvious to subtle. It’s important to pay attention to any tell-tale signs your AC system may be producing, as they can help you identify a potential problem before it leads to a more serious issue. If any of the above issues occur, make sure to call an experienced HVAC professional for assistance.

Once the repairs are complete, remember to have regular maintenance done on your AC unit each year to keep it running smoothly.

Benefits of Calling a Professional Technician

Investing in professional AC repair services is key to protecting your system and extending its life. A professional technician can inspect and service your unit to make sure it is functioning properly. They will be able to diagnose any issues and provide you with the appropriate repairs needed. Additionally, a good HVAC technician can also help you save money on energy bills in the long run by ensuring that your system is running efficiently.

Safety is also a key factor when it comes to AC repair. DIY repairs can be dangerous and should not be attempted without proper training and experience. A professional technician has the right tools, skills, and knowledge to perform any repairs safely and correctly.

By calling a professional technician for your AC repair needs, you can rest assured that the job is being done correctly while also protecting your system and saving money in the long run.

So don’t wait until it’s too late. If you notice any of the above warning signs, make sure to contact a professional technician for assistance as soon as possible.
