Living in Midlothian, Texas you expect cool, refreshing air to blow from your ducts when you turn on your AC in hot weather. Warm air blowing into your house is the last thing that you want on a sweltering Texas day. If this does happen to you, the best thing to do is call a heating and cooling professional to inspect your unit. An AC repair Midlothian technician can ensure that the problem does not get any worse and cause total unit failure. There are a few reasons why your AC may be blowing warm air. While some of these problems have straightforward, inexpensive solutions, others are more serious and will require professional AC service in Midlothian, TX.  

Take a look at some of the most common causes of warm AC air:

Electrical Malfunction

The first thing that you should do if your AC is blowing warm air is to check the circuit breaker. Often, outdoor units will lose power while the indoor unit continues to function just fine. If the circuit breaker seems okay, safely check for a blown fuse or a wiring issue. If one of these issues seems to be the culprit, do not attempt to fix it yourself. Call an AC technician right away so that they can quickly diagnose and fix the electrical issue  

Dirty Air Filter

Many homeowners don’t realize that a dirty air filter is more than just a collection of dust. It can actually impede your air conditioner from properly functioning if it is seriously clogged. A dirty air filter blocks air flow and causes your unit to work even harder and overheat. Once it overheats, it struggles to cool down and cycles warm air into the house. Air filters are something that you can easily change yourself. Most major grocery stores carry air filters so that you can pick one up with your weekly shopping. If you happen to need help replacing the air filter, call a certified Midlothian AC technician to lend a hand  

Leaking or Low Refrigerant

Refrigerant is the substance that keeps your home nice and cool by absorbing heat. Low refrigerant levels are one of the most common reasons as to why AC units blow warm air. Refrigerant loss could be caused by a leak, loose connection, corrosion or some other type of damage. This is not something that you should handle yourself. Avoid touching refrigerant at all costs as it poses a serious safety hazard. If you suspect a refrigerant leak, call an AC technician right away so that they can identify the cause of the leak and quickly it. In the case of low refrigerant, AC technicians will be able to fill your unit back up.  

Air Duct Leak

A leak in your air duct could be the cause of warm air blowing into your home. Even a small leak causes your air conditioner to work harder to cool the house, causing it to overheat. This issue could also result in higher energy bills than usual. An AC technician can determine if this is the cause of the problem. If it is, they can find and repair the leak or replace the duct system depending on the number of leaks and damage.  

Malfunctioning Thermostat

Be sure to take a look at your thermostat settings before you call anyone. Sometimes, you won’t realize that you have accidentally turned on the heat setting on our thermostat. You can also change out the batteries to ensure that your thermostat is functioning correctly. Sometimes thermostat wiring can become faulty, so don’t completely rule this out as a possible cause. While it may seem rudimentary to check the thermostat, if it does happen to be an accidental flip of the switch then you will have saved yourself quite a bit of money on an AC technician.  

Blocked or Dirty Condenser Unit

When you notice that your AC is blowing warm air into your house, be sure to check your condenser which is typically located outdoors. It is recommended that there are at least two feet of clearance around your condenser. Clear out any branches, large weeds, toys or other materials that may be blocking your unit. You can also quickly wipe it down with a wet rag to remove any built-up dirt and debris. If you notice an internal blockage, be sure to call an AC technician. They will be able to safely remove and clean any debris or blockages from your outdoor unit to keep it working like new.  

Compressor Failure

The most serious of all of these issues is compressor failure. The compressor jumpstarts the cooling process by circulating refrigerant. Many of the issues outlined above can actually cause compressor failure, which is why it is so important to schedule regular maintenance for your AC unit. Overheating and electrical malfunctions are only a few problems that can cause your compressor to go bad. If it does fail, you will have to get it replaced. This can cost hundreds of dollars and cause discomfort in your home while you wait for a replacement. If you suspect that your compressor is failing, call a technician right away so that they can assess the unit and determine the right course of action.
