Why is Your Air Conditioner Not Cooling? (5 Potential Reasons)

When your air conditioner isn’t cooling, you wonder if it’s time to call in a professional for AC service. However, it’s always best to know what could potentially be wrong with your system. Why? Because it protects you against being overcharged or tricked into making a purchase you don’t actually need.

There are several reasons why you should call for AC service when your air conditioner isn’t working. They include situations like a dirty air filter, an improperly set thermostat, a blocked condenser, a damaged heat pump, or a frozen evaporator coil.

Before you call your favorite HVAC repair company, take a look at what could be leading to your improperly working air conditioning system. Then, when you come in contact with them, you can give them a clear picture of what’s taking place. As a result, you’ll get your AC service completed more efficiently, and if you take care of it right away, you could save a bundle of cash too.

1. When the AC is Running But Not Cooling – It Could Indicate a Dirty Air Filter

Your air conditioner is operating, but you’ve noticed that the airflow isn’t quite what it usually is. If you’re lucky, that’s often a quick and easy fix. Over time, the air filter in your system will get clogged with dirt, dust, debris, and other contaminants. After it has time to accumulate, eventually, there will be no way that the air can get through like it used to. 

Replacing the air filter in your AC is something reasonably straightforward. However, you want to reach out to a qualified professional. If the air filter isn’t the only problem, you could find yourself thinking the problem is fixed when in reality, something else is still failing. An HVAC technician will do a more thorough assessment and catch any additional issues right away.

2. The Air Conditioner Isn’t Cooling to the Thermostat Temperature

Your thermostat is set to the desired temperature, but it seems to be getting warmer or not cooling off. Check your thermostat. Someone may have switched it to a different setting. Make sure that it is on the cooling label. If it isn’t, it could be the fan or on setting that needs to be adjusted.

A professional HVAC contractor will be able to identify right away how the thermostat should be set. In addition, if there are problems with the connection between the thermostat and the air conditioning system, the technician can fix the issue on the spot.

3. A Blocked Condenser Unit Requires AC Service

Take a look at your central air conditioner outside. It’s designed to allow outdoor air to come through the system and hit the condenser coil. That’s how the warm air is cooled. However, dirt, leaves, twigs, and other outdoor debris can clog up the fins where the air enters. If the air can’t get in, it is impossible to cool and push it into your home. 

If the condenser is blocked, your system is running much harder than it should, and that means all the other parts are getting overworked, and you’re paying more for the lack of energy efficiency.

A professional AC repair technician can easily and quickly clean out a blocked condenser unit. They have the appropriate tools and methods to ensure it’s done correctly and in a timely fashion.

4. The Heat Pump is Damaged

Many homeowners now use heat pump systems as air conditioners. A heat pump operates the same way as an air conditioner but also has components that help heat the home and cool it down. These are very involved pieces of equipment. If your heat pump isn’t cooling your house adequately, call in a professional to take a look. It could just be clogged, or something more serious is going on.

5. The AC Service Requires Attention to a Frozen Evaporator Coil

A frozen evaporator coil is easy to identify. For example, suppose you notice frost forming on the tubing, an inability to cool the property, increased utility bills, condensation drainage that is more than usual, or warm air being pushed into your living space. In that case, it’s likely something with the evaporator coil. HVAC contractors are trained in what to look for and know how to fix the problem to get the cool air needed to stay comfortable.

How Do You Fix an AC Unit That’s Not Working?

In short, you don’t. It’s never recommended that you try and fix your air conditioner on your own. It may seem pretty simple to handle, but when you open up the unit, you’ll find that it’s much more complex than what it appears from the outside. 

You need to hire a professional for all AC services for efficiency, accuracy, and safety. If your air conditioner isn’t working, getting someone over as soon as possible is ideal. The longer you wait, the worse it will get and the more expensive it will be.
