5 Reasons Why Your AC is Blowing Warm Air | Air Conditioning Service in Plano, TX
Air Conditioners are a necessity in the warm days of summer in Plano, TX. They maintain a comfortable environment in our houses and save us from the raging sun’s heat. Their cool air makes it possible for us to relax in our homes and work efficiently in our offices.
What if they start blowing warm air? Has it ever happened to you?
We are sure that if you are a regular air conditioner user, then, you must have called an air conditioning service in Plano, TX, at least once, to counter this issue.
Is it happening again? Are you confused that how a cool air blowing equipment can blow warm air?
This happens because like every other electrical equipment, air conditioning systems malfunction with use and lack of maintenance and repairs. They are composed of a number of different components and even if one of its parts malfunctions, then the whole system stops working properly.
Below we have provided 5 common reasons found by the technicians of air conditioning service in Plano, TX that force your air conditioner to blow warm air.
Thermostat Turned to Heat Mode
Okay, this sounds weird, but actually, it is one of the basic reasons for warm air from your HVAC system. Usually, we turn off our unit after winter and forget to adjust its thermostat for the summer. Sometimes, we even accidentally flip the switch of our HVAC system from cool to warm. So, if your system is blowing warm air, then, you should first check its thermostat before calling an air conditioning service in Plano, TX.
Refrigerant Leakage
One of the common reasons causing an air conditioner to blow warm air is a refrigerant leak. Usually, you won’t be able to see this leakage for a few days, however, you will feel it by the reduced efficiency and warm air blows.
Refrigerant leakage can take place due to various reasons. The common ones include heavy usage and lack of maintenance. Most of the time, people neglect the maintenance of their air conditioner prior to the summer season. As a result, the sudden load causes wear and tear to the components and eventually, refrigerant leakage. Sometimes, refrigerant leakage can take place due to poor assembly of its components in the installation step. Leakage can also take place due to a worn service valve.
Refrigerant leakages are dangerous, therefore, you should avoid confronting them on your own. If you notice any reduction in the cooling capacity of your unit, then, you should call an air conditioning service in Plano, TX to diagnose the issue and solve it accordingly.
Frozen AC Unit
Are you surprised by this? Well, most people are! The insides of the cooling unit of your HVAC system can freeze into a block of ice. Now, you must be wondering that if the AC is frozen, then, why is it blowing warm air? In theory, it should blow cooler air because of the presence of ice!
Well, dear readers, this is because the evaporator coil of your cooling system has frozen and the ice is blocking the flow of cool air into your house. As a result, you are forced to bear the warm air caused by the motor’s heat.
The condensation taking place in your AC has to evaporate. However, sometimes, people turn on their cooling units to the highest possible setting in an attempt to counter the scorching heat. This results in the build-up of condensation and freezes it if the temperature of your AC is below 32̊ F. You can avoid such a situation by keeping your thermostat settings around 70 to 72 ̊ F.
You can unfreeze your unit by turning it off for an hour or two. If the situation stays the same, then you should call an air conditioning service in Plano, TX to avoid any further damage.
Blown Breaker Switch
The outdoor unit of your HVAC system usually has a different power supply than your indoor unit. Sometimes, the on/off switch of your outdoor unit trips due to a bad breaker. This cuts down the power supply and it doesn’t turn on when you start your AC system. The internal unit of your system is responsible to circulate air throughout your house and it keeps working even though the external unit is powered off. As a result, you suffer from the warm air blown by the system.
If you notice that your system is blowing warm air, then, check the breaker and flip it back on. If this keeps occurring again and again then you should call an electrician because there might be an issue with the electrical system. However, if the breaker is not the case, then instead of taking matters in your own hands, you should contact an air conditioning service in Plano, TX to check your AC.
Clogged Air Filter
How long has it been since you last changed your air filter? Was it last year?
If yes, then you should change it immediately, because, air filters tend to accumulate dirt and other such debris over the span of AC’s usage. These contaminants clog them and negatively influence the working of your system. These clogged filters result in the malfunctions of other components and you are forced to bear warm air in the midst of summer.
You can change an air filter according to the instructions of the manual. If the situation pertains, then, there are chances that your system’s clogged filter has done the worst and you require an air conditioning service in Plano, TX to bring it back to working shape.
