If you’ve lived in Texas for at least one summer, you know how hot it can get. When it gets hot outside, most people spend more time in their air-conditioned homes to escape the heat. If your air conditioner isn’t working correctly, the temperature inside your house can reach 120 degrees on a 90-degree day, making it impossible to stay cool and comfortable at home, and you’ll have nowhere to go to escape the heat. Also, when it gets this hot in your house, you and your family are at risk for heat exhaustion and heatstroke.
If your air conditioning system experiences any of the following issues, it’s best to call a professional in air conditioning repair in Dallas, TX immediately. Further damage can occur if the problem isn’t addressed immediately, and it will be impossible to remain comfortable in your home.
#1 Restricted Airflow
When the air conditioner runs, you should feel a strong rush of cold air from the vents. If you feel minimal airflow, it’s best to schedule an appointment for air conditioning repair. Restricted airflow will affect your home’s temperature and won’t be as cool as you like. The unit must work harder to keep the house cool, consuming more energy, and your electric bills will increase. In addition, the extra work will strain the unit and can reduce the unit’s lifespan. Because restricted airflow can cost you more money than necessary, it’s best to call a professional in air conditioning repair.
A few issues can restrict the airflow, and you’ll need a licensed HVAC tech to diagnose and repair the problem.
- Damaged Air Ducts: The air ducts are hidden behind the wall, under the floor, or above the ceiling, so you won’t see any visible damage. Insufficient airflow is the only way to know there’s an issue with the ducts. If there’s a crack or break in the ducts or the sealing fails, the cold air will escape before reaching the vents, resulting in poor airflow.
An air conditioning repair tech in Dallas, TX can inspect the ducts for damage and make the necessary repair to restore adequate airflow, ensuring your home remains cool and comfortable all summer long.
- Broken blower: Your air conditioner has a blower, which is a fan designed to force the cold air to the vents throughout your home. If the blower runs too low or not at all, there will be insufficient airflow from the vents.
An air conditioning repair tech can inspect the blower to diagnose the issue and determine if it can be fixed or if replacing the unit is the best option. When the job is complete, adequate airflow will be restored.
- Clogged air ducts: Dirt, dust, and debris from your house will get into the air ducts and accumulate. Regardless of how clean you keep your home, up to five pounds of debris can accumulate in the ducts, creating a clog that restricts the airflow. Clogged air ducts can also put your family’s health at risk due to poor air quality. When the air conditioner runs, the debris from the ducts will circulate in the air, causing allergy symptoms.
An HVAC tech can clean the debris from the air ducts to restore sufficient airflow, and it’s recommended that you have the air ducts cleaned every three to five years to ensure adequate airflow and keep your family healthy.
Restricted airflow can affect the unit’s lifespan and your bank account, so it’s best to address the problem immediately.
#2 The Unit Produces Warm Air
Your air conditioner will produce cold air if it’s working correctly, and if you feel warm air coming from the vents, it indicates an issue that should be fixed by an air conditioning repair professional in Dallas, TX. You can avoid an unnecessary service call by checking the thermostat and air filter. For the unit to produce cold air, the thermostat must be set to the cooling mode, and it must be warmer in the house than the thermostat setting. In addition, the fan must be set to auto. If it’s set to on, the fan will continue running between cycles, and you’ll feel warm air coming from the vents. Next, check the air filter. If it’s been a while since you replaced it and it is covered in dirt and grime, it will prevent sufficient airflow in the unit, causing it to overheat and produce warm air. If there are no issues with the thermostat setting or the air filter, it’s time to hire a professional in air conditioning repair.
A few issues can prevent the unit from functioning correctly, and you’ll need a professional to diagnose and repair the problem.
- Refrigerant leak: Refrigerant is essential for your air conditioner to produce cold air. When formic acid forms on the coils and buildup on the tubes creating pinhole leaks that will allow the refrigerant to leak, making it impossible for the unit to produce warm air.
If your unit was installed after 2010, a professional in air conditioning repair can fix the leak and refill the refrigerant. If your unit was installed or manufactured before 2010, the unit must be replaced. Older units use R-22 refrigerant, which is toxic and harmful to the ozone layer. R-22 was banned in the United States on January 1, 2020, so the HVAC tech won’t bother to fix the leak because they won’t have the R-22 refrigerant to refill the unit. The only way to keep your home cool is to replace the unit with a newer model that doesn’t rely on R-22 refrigerant.
- Frozen evaporator coils: The evaporator coils play an essential role in keeping your house cool and comfortable. They extract the heat and humidity from the air to begin the cooling process. The coils can freeze if there’s poor airflow in the unit, the coils are dirty, or the fan speed is too low. They can also freeze up if you run the air conditioner when it’s too cold outside.
A professional in air conditioning repair in Dallas, TX can thaw the coils and determine why they froze to prevent the problem from happening again. When the job is complete, the cool air will be restored, and your home will be comfortable.
- Faulty compressor: The indoor unit and outdoor compressor work together to keep your house cool and comfortable. If the compressor is broken, the indoor unit cannot produce cold air on its own, and you’ll feel warm air coming from the vents.
An air conditioning repair tech will inspect the unit to figure out why the compressor isn’t working and make the necessary repair.
Your house will get very hot very quickly if your air conditioner doesn’t produce cold air. It’s best to hire a professional in air conditioning repair immediately to restore the cold air so your house will be cool and comfortable.
#3 There’s a Foul Odor when the Air Conditioner Runs
Your air conditioner is designed to produce clean, odorless cold air. If you smell something strange when the unit runs, it indicates issues that could put your home and family at risk, so it’s best to call an air conditioning repair tech immediately. The smell in your house will help the tech determine what’s wrong.
- Burning: A burning smell when the unit runs indicates a wiring issue, and the foul odor is the least of your problems. A wiring issue can start an electrical fire that can destroy your house in minutes, so it’s best to turn off the air conditioner as soon as you detect the smell and then call an air conditioning repair tech in Dallas, TX. They can locate and replace the faulty wires, so you can safely run the air conditioner, and your home will remain cool and comfortable.
- Mold: A moldy smell indicates the presence of mold in the air conditioning system, and the most common place for mold growth is the air ducts. The ducts are hidden and dark, and condensation will form in the ducts when it gets humid in the house, creating the ideal environment for mold growth. This problem should not be ignored because mold in the air ducts can put your family’s health at risk.
Mold spores will circulate in the air when the unit runs, putting your family at risk for mold-related health issues, such as allergies, skin rashes, chronic headaches, and respiratory problems. If a family member has a chronic lung or respiratory condition, mold exposure will worsen the condition and symptoms.
A professional in air conditioning repair can eradicate the mold using an antimicrobial fogger, which can prevent future mold growth.
The mold could be in the unit if the air ducts are clean. Mold growth can occur if you fail to maintain the unit, which is much harder to eliminate than mold in the air ducts. You’ll need to replace the unit if the tech cannot eliminate every last mold spore, and it’s the only way to ensure your family stays healthy. If the tech can eliminate the mold, you should consider installing a UV lamp in the unit to prevent the problem from happening again.
Foul odors indicate issues that can put your house and family at risk, so it’s best to call an air conditioning repair tech in Dallas, TX as soon as you notice the smell.
#4 The Unit Isn’t Removing the Humidity from Your Home
Your air conditioner is designed to eliminate humidity, keeping your house cool and comfortable. If your home is humid even though the air conditioner is on, it’s time to call a professional in air conditioning repair. A few issues can prevent the unit from dehumidifying your home, and you’ll need a professional to find the cause and make the necessary repair.
- The thermostat fan is set to ON rather than AUTO.
- The evaporator coils are dirty, and if the issue isn’t addressed immediately, they will freeze, making it impossible for the unit to produce cold air.
- The unit is leaking refrigerant.
- There’s a leak in the ducts.
- The unit is too large for your home’s square footage, causing it to cycle frequently, so it can’t eliminate the humidity.
Humidity makes your home warmer and sticky, so it’s best to call an air conditioning repair tech as soon as the problem starts. When the tech completes the job the unit will eliminate the humidity, keeping your house cool and comfortable.
