When it gets very hot during the summer, you rely on your air conditioner to keep your home cool and comfortable. During the winter, you rely on your furnace to keep your home warm. Unfortunately, your AC and furnace aren’t impervious to damage and problems and may need to be repaired.
If your HVAC system experiences any of the following problems, it’s best to call a heating and AC repair service in San Antonio, TX.
#1 The Furnace Produces Cold Air
If you feel cold air coming from the vents when the furnace runs, a heating and AC repair service can help. A few issues can prevent the unit from producing cold air, including:
- The thermostat isn’t set correctly or is broken.
- The air filter is covered with dirt and grime, causing the unit to overheat.
- An issue with the high limit switch is caused by running the unit with a dirty filter for a significant period of time.
- The pilot won’t stay lit, preventing the unit from kicking on.
- If your unit doesn’t have a pilot, the flame sensor could be covered in dirt or grime or is faulty.
- A clogged condensate hose
- Issues with the gas valve
- Issues with the burner
A heating and AC repair service can send a tech to inspect the unit to determine why it isn’t producing warm air and resolve the problem. It’s best to make the call right away so your home will be warm again.
#2 The Air Conditioner Produces Warm Air
When the air conditioner is functioning correctly, you should feel cold air coming from the vents in every room of your house. If the unit produces warm air, you may need to hire a heating and AC repair service in San Antonio, TX.
Before making the call, it’s best to check a few things first to avoid an unnecessary service call. First, check the thermostat. The air conditioner won’t keep your home cool and comfortable if it’s not set correctly. It must be set to the cooling mode, and it has to be warmer in the house than the setting on the thermostat for the unit to kick on. Also, make sure the fan is set to auto. If you leave it on, the fan will continue running between cycles, and you’ll feel warm air coming from the vents.
Next, check the air filter. If you haven’t changed it in quite some time and it’s covered in dirt and grime, air won’t move through the unit, causing it to overheat.
If everything checks out on your end, it’s time to call a heating and AC repair service. A few issues can cause the problem, including:
- Frozen evaporator coils, preventing the start of the cooling process.
- There isn’t enough refrigerant in the unit to produce cold air due to a leak.
- The outdoor compressor isn’t working, preventing the unit from producing cold air.
An HVAC tech can inspect the air conditioner to figure out why it’s producing warm air so they can resolve the problem.
#3 Foul Odors
You shouldn’t smell anything when the furnace or air conditioner runs, and strange smells indicate serious problems that require a call a heating and AC repair service. Foul smells indicate issues that can put your home and family at risk, so it’s best to make the call immediately.
- Rotten eggs: If you smell rotten eggs in your home, it indicates a gas leak. Turn off the heat immediately if it’s on, and get everyone out of the house immediately. When everyone is safe outside, call 911. A gas leak can cause an explosion, and the fire department will have to cut the gas going to your home. When the fire department clears your house, and you can go back in, you’ll need to call a heating and AC repair service to resolve the problem before running the furnace.
- Mold: A moldy or mildew smell indicates mold in the air ducts. The ducts are dark, and condensation can form when it gets humid in your house, creating the perfect breeding ground for mold. Mold in the ducts requires an emergency call to a heating and AC repair company. When the heat or air conditioner runs, mold spores from the ducts will circulate in the air, creating a health hazard. Mold exposure causes health problems, such as allergies, respiratory issues, skin rashes, chronic headaches, and a weakened immune system. An HVAC tech can use an antimicrobial fogger to eradicate the mold, eliminating the risk of mold exposure.
- Burning: A burning smell indicates a wiring issue in the air conditioner or furnace and can start an electrical fire that can destroy your home in minutes. It’s best to turn the unit off immediately and hire an HVAC tech to fix the wiring.
Foul odors indicate serious problems that could result in a disaster, and it’s best to have the issue resolved immediately.
