Summers in Texas are very hot, and it’s not uncommon for the temperature outside to reach 90 degrees or higher. Without a functional air conditioner, the temperature inside can quickly reach 120 degrees or higher, making it impossible to remain comfortable in your home. Also, temperatures this high can put you and your family at risk for heat exhaustion or heatstroke, so it’s crucial that your air conditioner functions correctly.
If the unit experiences issues that affect the temperature, airflow or could put your home and family at risk, like the problems listed below, it’s best to call an AC repair company in Lewisville, TX immediately. The longer you wait, the hotter it will get in your house, and further damage can occur.
#1 The Unit Fails to Produce Cold Air
Feeling warm air rather than cold when the air conditioner runs is the most obvious sign it’s time to call an AC repair company. The problem could be due to something you can easily fix yourself, so you should check a few things before making the call.
- Make sure the thermostat is correctly set. It must be set to the cooling mode, and it has to be warmer in the house than the setting for the unit to kick on. Also, the fan must be set to auto to stop it from running when the unit cycles. If the fan is on, it will continue to run, and you’ll feel warm air from the vents.
- Check the air filter. If it’s been a while since it was last replaced, the dirt and grime on the filter will prevent adequate airflow, causing the unit to overheat, and it won’t produce cold air.
If everything checks out on your end, it’s time to call an AC repair company in Lewisville, TX. More than one issue can prevent the unit from producing cold air, and you’ll need an HVAC tech to determine the cause.
- Frozen evaporator coils will prevent the unit from producing cold air. The coils extract the heat and humidity from the house to begin the cooling process. The coils can’t do their job if they freeze, and an AC repair company can send a tech to thaw the coils. They’ll also try to figure out why the coils froze to prevent it from happening again.
- A refrigerant leak will prevent the unit from producing cold air because refrigerant is essential for the cooling process. Acid can eat away the metal over time, creating tiny holes that allow the refrigerant to leak. An HVAC tech can fix the leak and refill the refrigerant if the unit was installed after 2010. You’d need to replace the unit if it was installed before 2010 because R-22, the necessary refrigerant for older units, is toxic, depletes the ozone layer, and was banned in the United States.
- A faulty compressor will prevent the unit from producing cold air because the indoor unit won’t work if it’s broken. An AC repair company in Lewisville, TX can send a tech to fix the compressor and restore the flow of cold air to your home.
Your air conditioner won’t keep your house cool if it can’t produce cold air, and it’s best to resolve the problem as quickly as possible.
#2 Inadequate Airflow
You should call an AC repair company if you don’t feel a powerful rush of cold air from the vents when the air conditioner runs. A few problems can restrict the airflow, and you’ll need an experienced HVAC tech to determine the cause.
- The dirt and debris in your house can end up in the air ducts creating a clog that will restrict the airflow. The debris in the ducts will circulate in the air when the AC runs, affecting your home’s air quality and causing your family to develop allergy symptoms. An HVAC tech can clean the ducts to restore airflow and improve your home’s air quality.
- You can’t see visible damage to the ducts because they’re hidden, but you will notice minimal airflow from the vents. The cold air will escape through cracks, loose joints, or failed sealing before reaching the vents, reducing the airflow. An AC repair company can send a tech to inspect the ducts for damage and make the necessary repair.
- Your AC has a blower designed to force the cold air from the unit through the ducts and to the vents. The air won’t reach the vents if the blower isn’t working correctly, resulting in minimal airflow. An HVAC tech can repair or replace the blower, ensuring adequate airflow to keep your house cool and comfortable.
Poor airflow affects the temperature in your house, and it’s best to call an AC repair company immediately.
#3 Strange Odors
Your AC shouldn’t emit an odor, and you should call a professional immediately if you smell something when the unit runs. A moldy smell indicates mold in the ducts or the unit, putting you and your family at risk of mold exposure. Fortunately, an HVAC tech can use an antimicrobial fogger to eliminate the mold and prevent future growth.
A burning smell is caused by burning wire insulation due to a wiring issue. The problem could start an electrical fire if it isn’t fixed quickly, destroying your house in minutes.
