Texas summers are very hot, and your air conditioner becomes one of your most essential appliances when spring ends. Spending time outside can be uncomfortable when the temperature reaches 90 degrees or higher, and your air-conditioned home is a great place to escape the heat. If your air conditioner is acting up, you’ll have nowhere to escape the heat because your house will be very hot. The temperature inside can reach 120 degrees on a 90-degree day, putting your family at risk for heat-related health conditions, such as heat exhaustion and heatstroke.
The best way to ensure your family remains cool and comfortable all year is to hire a professional in air conditioning repair as soon as the unit experiences issues. The longer you wait to make the call, the longer your home will be hot and sticky, so it’s best to make the call immediately.
The following issues indicate it’s time to hire a professional.
#1 Reduced Airflow
You should feel an intense rush of cold air when your air conditioner runs, and if you feel minimal airflow, it’s time to hire an air conditioner repair tech. Insufficient airflow will affect your home’s temperature, and the unit must work harder than necessary. When your air conditioner works overtime, it will consume more energy, and your electric bills will increase. The extra work will strain the unit if you allow the problem to persist, reducing its lifespan, and you may need to replace it sooner than necessary. A few issues can cause reduced airflow, and you’ll need to hire a professional in air conditioning repair in Dallas, TX to find the cause and resolve the issue.
- Clogged air ducts: The air ducts deliver the air-conditioned air from the unit to the vents throughout your house. The dirt, dust, and debris in your house will accumulate in the air ducts over time, regardless of how often you clean. When too much debris builds up, it will clog the ducts, restricting the airflow. Clogged air ducts will also affect your home’s air quality. The debris in the ducts will circulate in the air when the unit runs, and your family can experience allergy symptoms.
Fortunately, an air conditioning repair professional can easily resolve the problem by cleaning the ducts. When the air ducts are debris-free, the airflow will be restored, and you can be sure your home’s air quality is safe.
- Damaged air ducts: The air ducts are hidden for aesthetic reasons, so if there’s any damage, you won’t be able to see it, and the only sign will be reduced airflow. The cool air will escape from the damaged area before reaching the vents, and you’ll feel minimal airflow when standing in front of the vents in your house.
A professional in air conditioning repair in Dallas, TX will inspect the ducts for breaks and the sealing to determine if it’s failing and fix the problem to restore sufficient airflow.
- Broken blower: The blower is responsible for forcing the cold air to the vents to ensure sufficient airflow. It will take time for the air to reach the vents if the blower isn’t working, resulting in insufficient airflow.
An HVAC tech will check the blower to determine if it can be fixed or if a replacement is the best option. The airflow will be restored when the blower is up and running again.
Insufficient airflow causes problems that can be costly, so it’s best to hire a professional in air conditioning repair in Dallas, TX as soon as the problem starts.
#2 The Unit Produces Warm Air
Air conditioners are designed to produce cold air and eliminate the humidity in your house. If you turn on the AC and you feel warm air coming from the vents, you may need to hire a professional in air conditioning repair.
The problem could be something you can fix on your own, so it’s best to check a few things before calling an HVAC tech to avoid an unnecessary service call. First, check the thermostat setting. It must be set to the cooling mode, and the temperature inside must be warmer than the thermostat setting. Also, 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 it was last replaced, the dirt and grime can prevent sufficient airflow in the unit, causing it to overheat and produce warm air.
If the thermostat and air filter are alright, it’s time to hire a professional in air conditioning repair. A few issues can prevent the unit from producing cool air, and you’ll need a licensed tech to determine the cause and fix it.
- Refrigerant leak: Air conditioners need sufficient refrigerant to produce cold air, and a refrigerant leak will deplete the supply, preventing the unit from producing cold air.
Leaks occur when formic acid erodes the metal over time, creating small holes that allow the refrigerant to leak. If your unit was manufactured after 2010. a professional in air conditioning repair in Dallas, TX will fix the leak and refill the refrigerant. However, you must replace the unit if it was manufactured before 2010. Older units use R-22 refrigerant, which is toxic and affects the ozone layer, and was banned in the US on January 1, 2020. The tech won’t waste their time trying to fix the leak because they won’t have R-22 to refill the unit, so replacing the unit is the only option.
- Frozen evaporator coils: The evaporator coils are essential for the cooling process to begin. They extract the heat and humidity from the air and use it to start the cooling process, and the evaporator coils cannot do their job if they freeze.
A few issues can cause the coils to freeze, such as dirt and dust covering the coil, insufficient airflow in the unit, low fan speed, or backed-up drain clogs. Also, if you run the unit when it’s too cold outside, there’s a good chance the coils will freeze.
A professional in air conditioning repair will thaw the coils to restore the cold air and will figure out why the coils froze to prevent it from happening again.
- An issue with the compressor: The indoor unit cannot produce cold air on its own and works with the outdoor compressor. If the compressor isn’t working correctly, you’ll feel warm air from the vents. You’ll need to hire an air conditioning repair tech to fix the compressor to restore the cold air.
A lack of cold air is a serious issue when it’s very warm outside, so it’s best to hire a professional in air conditioning repair in Dallas, TX as soon as the problem starts.
#3 Strange Smells When the Unit Runs
It’s normal to smell dust when you turn on the air conditioner for the first time during the cooling season, and the smell will dissipate within a few minutes. If you smell anything else when the unit runs, hiring a professional in air conditioning repair is best. Foul odors indicate problems that can put your home and family at risk, so it’s best to call a professional immediately.
- Burning: A burning smell indicates a wiring problem, and you’re smelling the wire insulation burning. If you don’t call a professional in air conditioning repair immediately, the issue can start an electrical fire that could destroy your house in minutes.
A professional in air conditioning repair can find the faulty wire and fix it before a disaster occurs.
- Mold: A moldy smell indicates mold somewhere in the system, and it’s most commonly found in the air ducts. The ducts are dark and hidden, and the humidity can create condensation, creating the perfect environment for mold growth. Mold spores will circulate in the air when the unit runs, putting you and your family at risk for health issues due to mold exposure, such as chronic headaches, allergy symptoms, burning eyes, and respiratory issues. If you or a household member has a chronic lung or respiratory issue, mold exposure will worsen the condition and the symptoms.
A professional in air conditioning repair in Dallas, TX will inspect the ducts for mold, which can be eradicated with an antimicrobial fogger. If they don’t find mold in the ducts, it’s likely in the unit and will be more challenging to eliminate. If the tech cannot eliminate every spore, you’ll need to replace the unit because a replacement is the only way to ensure your family remains healthy. If the tech can eradicate the mold, you should consider installing a UV light in the unit to prevent mold and bacteria growth.
Ignoring foul smells produced by the AC isn’t an option because your home and family will be at significant risk, and it’s best to hire a professional in air conditioning repair as soon as you detect the smell.
#4 It’s Humid in the House
Is your house very humid when the air conditioner runs? If so, it’s best to hire an air conditioning repair tech. The humidity will make your house feel warmer and sticky, so it’s best to resolve the problem immediately. You should check the thermostat before hiring a professional to avoid an unnecessary service call. The AC cannot eliminate the humidity if the fan is set to ON. When the fan is set to AUTO, it will shut off between cycles, and the moisture absorbed by the cooling coils will have time to drain through the condensate drain line. If the fan is set to ON, it will blow constantly, and the moisture on the coils cannot drain and will blow back into the house.
If the fan was already set to AUTO, it’s time to hire a professional. A few issues can prevent the unit from dehumidifying the house, and you’ll need a licensed tech to diagnose and fix the problem.
- Dirty evaporator coils: The evaporator coils use the heat and humidity in the air to start the cooling process. If they’re covered in dirt and grime, they can’t do their job, and your house will remain humid. The tech can clean the coils so they can eliminate the humidity effectively.
- Refrigerant leak: The refrigerant in the unit moves the heat and moisture out of the home and into the outside air. A refrigerant leak will prevent the unit from doing its job, and you’ll need a licensed tech to resolve the problem.
- Damaged air ducts: A leak in the ducts will allow the humidity outside to leak into your home, making it very humid inside the house. Fortunately, fixing the ducts will resolve the problem, your house will be cooler, and the humidity will be eliminated.
It’s best to hire a professional in air conditioning repair in Dallas, TX, as soon as your house gets humid. Waiting too long will affect your home’s comfort and increase mold growth risk.
