What to Do If Home Air Conditioning Not Cooling

home air conditioner not cooling

At Davis Home Services, we’ve served as air conditioner repair professionals in Burlington for 20 years. We offer full-service heating, AC, and plumbing services. Whether you need an emergency service or a scheduled house call, we have you covered.

With hot weather around the corner, now is a good time to check the inner workings of your system. Just as you would check your tires before a long road trip, you should also scrutinize your AC system from top to bottom before outdoor temperatures rise. A detailed analysis of your system components can root out small or significant issues.

Once they find problems, our skilled technicians will promptly rectify them. In between such service visits, you can also do your part to keep an eye out for potential problems. If your home air conditioner is not cooling the internal environment, this is a sure sign that something isn’t right somewhere in the network.

Keep an Eye Out for These Common Symptoms

If you have a damaged part in your AC network, it is always best to locate the part before things get worse. When such components go bad, they often exhibit similar types of symptoms. Take note of these signs and report your findings to our professionals. 

Here are some common reasons why your home air conditioner is not blowing cold air:

Incorrect Sizing

Air conditioning units come in all sorts of shapes and sizes. Window air conditioners, room units, and central air conditioners are examples of these size differences. As it turns out, air conditioning units need to be large enough to cool the spaces they occupy. 

Air conditioners that are the wrong fit for the spaces they cool can cause numerous problems. Overly large AC units will cool spaces too much, causing inefficiency. Overly small air conditioning systems will struggle to maintain temperature settings, leading them to run for excessive amounts of time. 

To determine the right system size, skilled technicians must consider many factors. Some factors include the number of zones, square footage of the home, insulation levels, and local weather patterns. Once they have this information, they can factor in the efficiency levels of the AC units they use. 

A technician’s goal is to find the best balance between AC unit capacity levels and internal home conditions. Once they determine this balance, they’ll know that they have the right-sized system.

Evaporator Coil Frost

The evaporator coil performs vital functions within your AC unit. Due to its placement, warm air flows over its coils. This air loses humidity and heat in the process. 

In a malfunctioning system, the evaporator coil sometimes gets too cold. If the temperature drop persists, the coil can freeze over completely. Naturally, a frozen evaporator coil cannot do its job correctly. 

If you have a frozen evaporator coil, you will likely notice a drop in your AC’s overall cooling capability. These parts are complex, hard to reach, and require special tools for AC repairs. So, when you notice frost or ice on your evaporator coil, always call our professionals.

Condenser Blocks

Another component of small and large AC systems is the condenser. This essential part returns hot refrigerant gas into a liquid state. Internal pumps then route this liquid back through the system to maintain the cooling and heating cycle. 

Condensers usually sit outside of buildings. Even though technicians place them strategically, condensers are still subject to occasional blockages. For example, fallen leaves, grass, dirt, or other debris can clog the condenser coil’s external parts. 

Once debris blocks the condenser, the unit will struggle to cool itself down. This loss of cooling capability can raise temperatures within homes and contribute to premature condenser failure.

Faulty Thermostat

The thermostat in your air conditioning unit works in tandem with logic control technology. Modern smart thermostats work almost automatically to preset temperatures to levels of your liking. If these complex devices stop working, they throw the entire system out of balance. 

If your thermostat is set to a low temperature, but your system still isn’t blowing cold air, you may have a faulty thermostat. Because these units include computerized controllers, it always pays to call an expert to deal with a malfunctioning thermostat.

Leaking Coolant

The refrigerant essentially acts as the lifeblood of your commercial or home air conditioning system. As it journeys through your system, the refrigerant will continually transition between liquid and gas physical states. These transitions create plenty of opportunities for the coolant to leak from faulty connection lines or devices. 

Refrigerant leaks are common. If you notice a loss in cooling capacity, our skilled technicians can ensure that your refrigerant levels are where they should be.

Clogged Air Filters

Your AC system includes air filters in its design. These filters trap various pollutants and particles, keeping them out of your indoor environment. If left untouched, these contaminants build up in filter fibers and can cause complete blockages. 

In turn, locked air conditioning filters reduce airflow levels. As a result, your system will work harder to circulate air throughout your home. Clogged filters also cause a drop in cooling capacity and warmer indoor temperatures.

Heat Pump Complications

Heat pumps are effective alternatives to air conditioning systems. 

Heat pumps have some parts in common with mainstream air conditioning systems. Like these mainstream systems, heat pump components also fail. One symptom of heat pump failure is the loss of internal cooling capability.
