Air conditioners can break down for a very wide range of reasons. If your AC unit has recently started blowing out warm air, then it is important to take action right away. You can call Tarpy Plumbing, Heating & Air to schedule a repair today and get the problem resolved once and for all. The fix might be something as simple as a filter swap, or it could be a little more complex. When we service an AC unit that is blowing warm air, here are a few of the most common problems we look out for.

Dirty Air Filters

Perhaps the most common reason for an air conditioner blowing warm air is dirty air filters. If you do not regularly maintain your AC unit, the filters can become clogged with dust, lint, dander, and other forms of dirt. The inability of air to flow easily through the system can cause the evaporator coils to freeze, resulting in warm air blowing through your home. Our technicians can quickly clean or replace your filters to get the system cooling efficiently once again. As a result, your home should feel cooler and the system’s energy efficiency could be better. You might even notice an increase in your indoor air quality!

Low Refrigerant

The purpose of refrigerant fluid in an air conditioning system is to absorb heat from the air. If a leak causes the refrigerant levels to drop, then the unit will not be able to cool air properly. As a result, the air blowing from the unit will feel warm.

It is vital to find the source of the leak and repair it, or the problem will soon recur. Leaking refrigerants can also be a safety and health hazard. To detect a refrigerant leak, you can watch out for wet patches, hissing sounds, or a build-up of ice on the outdoor unit. Call us right away to deal with your refrigerant leak if any of these signs are present.

Faulty Thermostat

Sometimes, air conditioning systems blow warm air due to problems with the thermostat. First, check the settings to make sure your desired temperature is set correctly. If the system still blows warm air, call us for thermostat recalibration or replacement. Replacing an old thermostat can bring multiple benefits, as you can opt to replace it with a new programmable thermostat. Programmable thermostats can help you save money by ensuring your AC is only running at times when you need it. Get in touch today to find out more about thermostats and the potential costs and benefits of replacement.

Dirty Condenser Coils

The role of condenser coils is to remove heat from the air and then vent that heat outside of your home. As the condenser coils are in the outdoor unit, they are exposed every day to weather and outdoor pollution. Over time, grime and dirt can build up on the coils, impeding their ability to transfer heat.

As part of our regular maintenance checks, we clean condenser coils to prevent too much dirt from building up. Get in touch today to schedule a repair or maintenance check.

Frozen Evaporator Coils

Evaporator coils can freeze as a result of filters being blocked, preventing cold air from flowing out of the unit. Cleaning or replacing the filters is relatively straightforward, but it is also necessary to clean the frozen coils. Our technicians can thaw frozen evaporator coils safely and take action to prevent them from freezing again.

Leaking Ducts

Small holes or tears in the ducts can allow cooled air to leak out into your home’s crawl spaces, which is a waste of energy. Warm air can seep in and blow through the vents, where airflow might also be noticeably weak. One key sign of leaking ducts is energy bills that suddenly start to climb higher and higher. You might also certain areas of your home don’t get as cold or warm as they used to.

Blocked Drain Line

The drain line of an air conditioning system allows wastewater to drain away from the unit. If a clog forms in the drain line, water backs up and can damage the internal parts of the AC. Water can also leak out of a clogged drain line, causing serious damage to your home. You might notice mold growth close to the unit if a leak is occurring. Regular maintenance can help to prevent drain line clogs. Our technicians can also clean and repair damaged drain lines. Please call us today if you are having problems with your AC unit’s drain line.

Fan Problems

Problems with the fan in your air conditioning system can cause airflow to feel warm and weak. The issue might be a build-up of debris and dirt inside the fan. Alternatively, the fan might have a faulty motor or a worn fan belt. Reach out to us today and we will figure out what the problem is and either repair or replace the fan. Just don’t wait too long, as the fan not working properly could lead to compressor failure over time.

How to Deal With an AC Unit Blowing Out Warm Air

The air blowing from your air conditioning vents should feel noticeably colder than the general air inside the room. Place your hand in front of the vent to see if you need to call for an AC technician to investigate. If the air coming from the vents is cold, but your room still feels too warm, the airflow from the vents might be blocked. Move furniture away from the vents to optimize the flow of air into the room.

Many of the problems that can lead to an air conditioner blowing out warm air get worse if left unaddressed. Tarpy Plumbing, Heating & Air can carry out timely repairs to protect your AC system from further damage. Contact us today to find out why your system is blowing warm air and get it fixed.
