While enjoying the cooling power of your home’s AC system can provide you with a comfortable temperature throughout your home, you’re likely to run into AC problems at some point. At Hearn Plumbing Heating and Air, our passion is providing you with quality service that can help you assess your home’s AC unit when it isn’t running properly.
Top AC Issues You Might Encounter
AC Isn’t Blowing Cold Air
A common AC issue is when your air conditioner is not cooling the way that it’s supposed to. Sometimes the cause is simple, like a thermostat setting, a tripped breaker, or a dirty air filter. Other times, it points to low refrigerant from a leak or a failing part, which needs a professional diagnosis.
AC Unit Is Freezing Up
If you notice ice building up on your AC coil or refrigerant lines, it usually means something is restricting airflow or refrigerant levels are low. Checking things like the air filter, blower fan, ducts, and vents for obstructions may be all it takes to get your unit up and running smoothly once more. Turn the system off to let it thaw, and call a technician if the problem returns.
Refrigerant Leaks
With most leaks occurring within the coolant lines of your AC unit, it can be tricky to detect right away. Warning signs include weak cooling, hissing or bubbling sounds, ice on the refrigerant lines, and oily residue around fittings or connections. In this scenario, you should shut off your unit and call your local HVAC professionals to inspect, diagnose, and repair any issues that deal with refrigerants.
AC Unit Is Making Too Much Noise
No one knows the sounds of your home like you do. That’s why when you hear things such as squealing, banging, or grinding noises coming from your air conditioner, it can be a sign of serious problems. While loose parts, a failing motor, or worn components may be the cause of these noises, you need to get a professional inspection to ensure the safety and efficiency of your home’s AC unit.
AC Won’t Turn On
When your air conditioner isn’t turning on, it’s often due to an electrical issue. Whether it is from a tripped breaker or a faulty thermostat, you should never attempt to fix electrical problems on your own without the proper training and equipment.
Blocked or Clogged Drains
When drains become blocked or clogged, it impedes the proper flow and disposal of water from your AC unit. This can lead to water leaks, water damage, and other issues that a technician can often resolve by clearing debris and obstructions from the condensate line.
AC Unit Is Running Constantly
One of the most common AC problems is when your air conditioning unit runs constantly to cool your home. This can happen for a variety of reasons. Start by checking your thermostat settings and replacing a dirty air filter. If your unit still won’t cycle off, it’s time to call in the professionals to get your system inspected and repaired by a certified HVAC technician.
Short Cycling
If your AC turns on and off every few minutes, it’s short cycling. This can be caused by an oversized unit, a thermostat problem, low refrigerant, or an electrical issue. Short cycling wears out parts faster and wastes energy, so it’s worth having it checked.
When to Call for AC Repair
Some issues, like a dirty filter, are easy to handle on your own. But refrigerant, electrical, and motor problems should always be left to a professional. If your system is struggling, our team provides fast, reliable AC repair to get your home cool again.
Frequently Asked Questions About Common AC Problems
Why Is My AC Running but Not Cooling?
A dirty air filter, incorrect thermostat setting, low refrigerant, or a problem with the outdoor unit can all cause this. If simple checks don’t help, schedule a professional inspection.
Can I Add Refrigerant to My AC Myself?
No. Refrigerant should be handled by a certified technician. If your system is low, there’s usually a leak that needs to be found and repaired first.
How Can I Prevent Common AC Problems?
Change your air filter regularly, keep the outdoor unit clear of debris, and schedule AC maintenance every year before the cooling season.
