The HVAC system in your Frisco, TX home is essential in keeping your home comfortable. You rely on your furnace during the cold winter months to keep the house warm and toasty. During the summer, you rely on the air conditioner to keep your home cool and comfortable. If any part of the HVAC system stops functioning correctly, it can affect the temperature in your home and could cause other issues. In addition, ignoring the problem will result in further damage with a higher price tag; therefore, it’s best to call a heating and AC repair company right away.
DIY HVAC repairs aren’t recommended because your HVAC system is complex. If you make a mistake while attempting a DIY repair, you could do more damage to the HVAC system. In addition, working with a propane, natural gas, or oil-fueled furnace is extremely dangerous if you don’t have the proper training.
If your HVAC system experiences any of the following issues, schedule an appointment with a heating and AC repair company right away.
#1 The Furnace Isn’t Producing Warm Air
Your furnace is designed to heat your entire home during the winter. If you feel cold air coming from the vents when the furnace runs, you may need the help of a heating and AC repair company.
You should check a couple of things before making the call to avoid an unnecessary service call. First, check the thermostat setting. Setting errors are a common cause of this problem, and you should make sure the thermostat is set correctly. First, check the mode setting. It has to be set to the heating mode for the furnace to produce heat. Next, check the fan setting. If it isn’t set to auto, the fan will continue running between cycles, and you’ll feel cold air coming from the vents. Finally, the temperature has to be set higher than the temperature in your house for the furnace to produce cold air.
Next, check the furnace filter. You have to replace the filter regularly, and the frequency depends on the filter size. For example, a smaller 1 to 2-inch filter should be replaced every one to three months, and a larger filter that’s 5 to 6-inches should be replaced every 9 to 12 months.
If everything checks out on your end, it’s time to call a heating and AC repair company. A few issues can prevent the furnace from producing warm air, and you’ll need an HVAC professional to troubleshoot and repair the furnace.
- Damaged pilot light: If you have an older furnace, it has a pilot light that has to remain lit for the unit to produce warm air. If the pilot light doesn’t stay lit, a heating and AC repair company can send a tech to figure out why the pilot won’t stay lit and make the necessary repair, and your house will be warm and toasty again.
- Dirty flame detector: Newer furnaces don’t have a pilot light and have a flame detector to complete the heating cycle. The furnace will produce cold air if the flame detector is covered in dirt and grime. Fortunately, an HVAC tech from a heating and AC repair company can inspect and clean the component, and the furnace can heat your home.
- Clogged condensate lines: Newer furnaces have condensate drain lines to remove moisture from the unit. If the line is blocked, the burners will deactivate, and you’ll feel cold air when you stand in front of the vents in your Frisco, TX home.
A heating and AC repair company can send a tech to unclog the line, allowing the furnace to produce warm air.
When it’s cold outside, you rely greatly on your furnace; therefore, you should call a heating and AC repair company immediately if it isn’t producing warm air.
#2 The Air Conditioner Isn’t Producing Cold Air
Frisco, TX, summers are very hot, with temperatures reaching 90+ degrees most days. When it’s this hot outside, most people spend more time in their air-conditioned homes to escape the heat. If your air conditioner isn’t producing cold air, it’s best to call a heating and AC repair company right away. Without an air conditioner, your home can reach 120 degrees on a 90-degree day, which is dangerously hot, putting your family at risk for heat-related illnesses; therefore, the problem should be resolved quickly.
Before making the call, you should check the thermostat and the air filter, the same as with a faulty furnace. Instead of setting the thermostat to the heating mode, make sure it’s set to the cooling mode, and the temperature has to be warmer in the house than the thermostat setting for the unit to produce cold air.
If the filter is clogged with dirt and debris, the air won’t move through the unit the way it should, causing the AC to produce warm air, and changing the filter will solve the problem.
If the thermostat is set correctly and the filter is clean, it’s time to call a heating and AC repair company. A few issues can cause this problem, and you will need a professional to troubleshoot and repair the problem.
- Refrigerant leak: The air conditioner in your Frisco, TX home relies on refrigerant to produce cold air. Over time, formic acid can eat away at the metal, creating small holes which allow the refrigerant to leak, and the unit can’t produce cold air.
If your air conditioner was installed in 2010 or later, a heating and AC repair company can send a tech to repair the leak and refill the refrigerant. If the unit was installed before 2010, you have a serious problem on your hands. Older units use R-22 Freon, which was banned in the U.S. because it’s highly toxic and depletes the ozone layer. The tech could fix the leak but won’t have the R-22 to refill the unit, and you will need to replace the air conditioner.
- Frozen evaporator coils: The unit’s evaporator coils extract the warm air and humidity from the home to start the cooling process. If the evaporator coils are frozen, they can’t do their job, and the unit won’t produce cold air. A few issues can cause the coils to freeze, including:
- Poor airflow
- Faulty drip pan
- Dirty air filter
- Dirty evaporator coil
- Low refrigerant
- You ran the air conditioner when it was too cold outside.
- A heating and AC repair company can send a tech to your home to thaw the coils and figure out why they froze in the first place to prevent it from happening again.
- The compressor isn’t working: The indoor AC unit and the outdoor compressor work together to keep your home cool and comfortable. If there’s no power going to the compressor or it stops working, you’ll feel warm air coming from the vents.
A heating and AC repair company can send an HVAC tech to inspect the compressor to figure out why it isn’t working and make the necessary repairs.
You need your air conditioner when it gets hot outside; therefore, if you feel warm air coming from the vents, you should call a heating and AC repair company right away.
#3 Strange Smells When the Unit Runs
When running the heat or air conditioner in your Frisco, TX home, the unit should produce clean, odorless air. If you smell something strange when the furnace or air conditioner runs, you should call a heating and AC repair company immediately. Strange smells indicate serious problems that can put your home and family at risk. The odor in your home can give the HVAC tech an idea of what’s causing the problem to make the necessary repair.
- Rotten eggs: A rotten egg smell in your Frisco, TX home indicates a gas leak, which is a very dangerous situation. As soon as you notice the smell, turn off the heat, get your family out of the house and call 911. A gas leak can cause a deadly explosion that can destroy your home and isn’t something that should be ignored. The fire department will cut the gas service to your home and open the windows to air it out. When they let you know that it’s safe to go back inside, schedule an emergency appointment with a heating and AC repair company. They will send a tech to your home to fix the leak, making it possible for the gas to be restored to your home, and you can turn on the heat.
- Burning: A burning smell when the heat or air conditioner runs indicates an electrical or wiring issue. This is a very serious problem because any electrical issues can start an electrical fire, destroying your home and injuring or killing any family members who don’t get out in time.
A heating and AC repair service can find the electrical problem and make the necessary repair as quickly as possible, ensuring the safety of your home and family.
- Mold: A moldy smell when the heat or air conditioner runs indicates mold in the air ducts. The air ducts are responsible for delivering cold or hot air from the unit to the vents throughout your home. The ducts are hidden behind the walls, under the floor, or above the ceiling for aesthetic purposes and are dark. When it gets humid in the house, condensation will form in the ducts, creating the perfect environment for mold growth. When the heat or air conditioner runs, mold spores will circulate in the air, putting your family’s health at significant risk. Mold exposure causes several health conditions, including:
- Respiratory and breathing issues
- Allergy symptoms
- Chronic headaches
- Eye irritation
- Skin rashes
If you or someone in your home has a chronic lung or respiratory condition, mold exposure will worsen the symptoms and condition.
A heating and AC repair company can send a tech to your home to inspect the air ducts for mold. If they find any, it can be easily eradicated with an antimicrobial fogger, which will also prevent mold growth in the future.
If you smell mold when the air conditioner runs and the air ducts are clean, there’s likely mold in the air conditioner, often due to neglecting to maintain the unit regularly. Mold in an air conditioner is more challenging to eradicate than mold in the ducts. If the tech can’t eliminate all of the mold, you will need to replace the unit.
When the HVAC system runs, foul smells indicate a serious problem that can put your home and family at risk; therefore, it’s best to schedule an emergency appointment with a heating and AC repair company the minute you detect the smell.
