AC Repair in Kingwood, TX: Why Is My AC Blowing Hot Air? - Guy's AC & Heating

Summers in Texas can be pretty muggy and hot, depending on where you are. Temperatures can range from 85 to 100 degrees throughout the Lone Star State. A functioning air conditioning unit is key to staying cool and comfortable during the summer. 

Imagine walking into your home after a long day hanging out outside, only to discover that your house is warm. If your AC is blowing hot air, you need to get it fixed fast. 

This guide will discuss why your AC might be blowing hot air. Learn what you can do to diagnose the issue and how an AC and heating tune-up can help. 

Your Thermostat Is Set at the Wrong Temperature

If you notice your air conditioner is blowing hot air, your thermostat might’ve gotten switched to the “heat” setting. This problem is an easy fix. You need to change your thermostat to the “cool” setting. 

You should also check to see if your thermostat’s batteries are working. The thermostat temperature might also have been set to a higher temperature than you wanted. 

Another thing to evaluate is if the fan’s settings are set to “on.” You might think your fan should be on while your air conditioner is running, but it’s counter-productive. 

If the fan is set to “on,” it will get blown through your vents at all times. That means warm air will get blown out when your air conditioner cycles off. 

Your thermostat should be set to “auto.” The fan will only work when the air conditioner blows cold air.

If you’ve checked your thermostat and it’s set to “cool” and “auto,” you might have another issue. Search for “AC repair near me” to find a qualified company in the Texas area. 

Your Outdoor Unit Isn’t On

Most home air conditioning units are made up of two units. They are the following:

  • Indoor Unit: Blows air inside of your house
  • Outdoor Unit: Cools the hot air down 

If you discover that your indoor unit is blowing hot air, your outdoor unit might not have power. Without power, it can’t cool the warm air down. One of the first steps is to check to see if the on/off switch on your outdoor unit is switched to the “on” setting. 

A blown fuse or tripped circuit breaker are the common causes of a powered-down outdoor unit. Check your fuse panel or circuit breaker. If it’s not sending power to your outdoor unit, you know your problem.

Low Levels of Refrigerant 

Air conditioner leaking is another common reason it might be blowing hot air. If your unit doesn’t have the right amount of refrigerant, it can’t complete its cooling cycles.

Low refrigerant levels are a common cause of air conditioners blowing hot air. Unfortunately, this is not a problem that you can DIY fix yourself. You’ll need to search for a heating and cooling maintenance company to remedy the issue. 

Some other signs of a refrigerant leak might include:

  • High power bills
  • Frozen coils
  • Hissing noises coming from the unit

A professional AC repair company will fix your refrigerant leak. They’ll also restore your refrigerant levels so you can get up and running as soon as possible. 

The Coils Are Dirty

An essential component of your air conditioner is the evaporator coils. There’s a box surrounding the coils that are exposed to the elements. Since it’s exposed to weather, it can sustain damage.

Dirty coils can also affect your indoor air quality. The following items can also get stuck in the coils:

  • Grass
  • Critters
  • Debris
  • Dirt

As these substances build up on the coil, they can interfere with its operations. It’s essential that you keep the area around your condenser box clear. The area needs around two feet of cleared-out space to operate efficiently. 

Compressor Failure 

The compressor of your air conditioning unit circulates refrigerant throughout the system. Since it’s so important, it requires a lot of electricity to function. 

An old compressor uses more electricity each year. It can sometimes trip your circuit breaker by pulling in too much electricity. As a result, your air conditioner will blow hot air. 

Old age can sometimes result in contaminants getting inside your air conditioner’s system. Metal particles, like rust, can block the unit’s refrigerant from functioning correctly. 

The last thing you want is a grounded compressor. A grounded compressor is when the motor’s wiring has gotten severed. If this is the case, you’d need a new compressor or air conditioner unit. 

It can be challenging to determine if the compressor is why your air conditioner is blowing hot air. Search for “heating and cooling near me” to find a reputable HVAC company. 

It’s Time for a New Unit

Your air conditioner might be blowing hot air because it’s reached the end of its lifespan. When properly maintained, an air conditioner can last up to 20 years. Staying on top of yearly maintenance is essential to prolonging your unit’s longevity. 

If you’re on top of routine maintenance and your unit is still struggling, you might need to consider purchasing a new unit. An experienced HVAC professional can provide you with recommendations and advice.
