With temperatures in New Jersey reaching the upper 80’s, a broken air conditioner leaves you uncomfortable and longing for cooler temperatures. One of the most common problems is an air conditioner blowing warm air.

In this blog, we explain why your AC unit may be running but failing to cool your home, the benefits of regular maintenance, and how AC maintenance from Home Allegiance Heating & Air can help you stay cool all summer long.

How Your Air Conditioner Cools Air

Understanding how an air conditioner works on a basic level can help you discover what exactly is wrong with your unit. Your air conditioner works by circulating refrigerant between the indoor evaporator coils and outdoor condenser coils. Throughout the process, the coolant changes from a liquid to a gas, absorbing heat from your indoor space and carrying it outside, where it evaporates. Your AC might be turning on and the fan blowing, but if there is an issue with the refrigerant, compressor, or other parts, you won’t feel cool air.

Reasons Your AC Unit Blows Warm Air

Warm air is one of the most common symptoms of a broken air conditioner, because of the various AC repairs in Hamilton Township, NJ it can cause. Below we will examine the most common reasons an AC is running but not cooling.

Dirty Condenser Coils

The condenser coils are in the outside unit of your air conditioning system and are responsible for liquifying the refrigerant. They are vulnerable to accumulating dirt and debris, which prevents your air from cooling properly. With dirty coils, your air conditioner works harder, loses its cooling efficiency, and risks more severe damage from overheating.

Compressor Problems

The compressor works in conjunction with the condenser to liquefy the refrigerant and pump it through the coils. Then, the compressor fan moves warm air outside. Growling noises are one indication your compressor is faulty.

Frozen Evaporator

The evaporator coils are responsible for cooling the air the AC fan blows over them. They house the liquid refrigerant, which absorbs the warm air and evaporates, returning to its gaseous state and taking the warmth outside. It’s the component most likely to experience a refrigerant leak. When your evaporator coils leak or get dirty, they can freeze. Since the component is inside the AC unit, you might not notice the freezing until it’s severe. Check for these early warning signs:

  • Higher utility bills as the air conditioner becomes less energy efficient
  • Warm air blowing from your AC unit
  • Excessive condensation

For more severe cases, you’ll notice ice building up in your unit. Give the expert Home Allegiance technicians a call for AC repair in Freehold, NJ.

Dirty Air Filter

Air filters ensure that your air is free from particles that exacerbate your allergies or respiratory issues. Over time, they build up dirt and dust. When they’re caked with debris, it hinders your air circulation and causes warm air to disperse throughout your home. Because a dirty air filter requires your air conditioner to work harder, failing to change or clean it can overheat your AC unit or lead to an AC breakdown in Hamilton Township, NJ.

Faulty Ductwork

Your home’s ducts carry the air throughout your home. Over time, they can build up dirt, develop leaks, or lose insulation. In these instances, when the cool air travels from your air conditioner to your rooms, it picks up heat and becomes lukewarm by the time it reaches its destination.

Electrical Problems

Several electrical issues can prevent your air conditioner from running properly. When your AC unit turns on and off quickly regardless of your target temperature, professionals call it “short cycling.” Several issues can cause short cycling, so it’s more a symptom than a problem.

You might also experience your air conditioner not turning on at all or your circuit breaker tripping frequently. Both these indicate a more serious electrical problem either with the AC unit itself or your electrical system as a whole.

Refrigerant Issues

Refrigerant is how your AC cools the air, so when it’s low, it can’t run properly. As the AC unit ages, your refrigerant can leak. Your air conditioner specialist can detect the leak, repair it, and safely dispose of the toxic refrigerant that leaked.

Broken Thermostat

If you suspect your thermostat is causing the problem, first check to make sure it’s set properly and has working batteries. Many homeowners call us for AC repair in Robbinsville, NJ and surrounding areas only to realize the thermostat had improper settings. If that doesn’t help, it may be too old or need recalibration, which is a service performed by an HVAC company in Hamilton Township like Home Allegiance.

Proper AC Maintenance To Avoid Warm Air

You can prolong your air conditioner’s life expectancy and avoid costly repairs by practicing these easy maintenance tips.

Annual Checkups

The majority of reasons why your air conditioner is blowing warm air can be avoided by scheduling annual AC maintenance in Hamilton Township, NJ. Air conditioning maintenance prevents costly repairs and uncomfortable breakdowns by catching AC problems early. A certified Home Allegiance technician will examine each component of your air conditioning system and provide repairs and preventative tasks. This service ensures your AC system is prepared for summer and is recommended to schedule every spring.

Frequent Air Filter Checks

Depending on your air filter, it needs replacement or cleaning every 30 to 90 days. If you run your air conditioner constantly, have pets, or reside in an area with lots of pollution, you may need to change it more frequently.

Clean Your Ducts
