You rely on your HVAC system most of the year. You rely on your heating system to keep your home warm during the cold months and your air conditioner during the hot months.
If something goes wrong with either part of the HVAC system, your home can get dangerously hot or cold, and you’ll need an HVAC professional to fix the problem.
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, as soon as the trouble starts.
#1 The Furnace Produces Cool Air
Your furnace is designed to produce warm air to keep your home comfortable when it’s cold outside. If the furnace produces cool air, your home will get very cold, and extra layers of clothing and blankets won’t be enough to keep your family warm.
A few issues can prevent the furnace from doing its job, and an incorrectly set thermostat is one of them. Before calling a heating and AC repair service, it’s best to check the thermostat to avoid an unnecessary service call. The thermostat must be set to the heating mode, and it has to be cooler in the house than the thermostat setting. Also, the fan must be set to auto. Adjusting the thermostat will solve the problem if you had the thermostat set wrong.
If the thermostat is correctly set, you’ll need to hire a heating and AC repair professional to figure out why the unit isn’t working correctly, and there are several potential causes.
- The pilot light is damaged.
- The air filter is dirty, preventing adequate airflow.
- Dirt and grime on the flame detector
- The condensate lines are clogged.
An HVAC professional can diagnose and resolve the issue, restoring the heat in your home.
#2 The Air Conditioner Produces Warm Air
Your air conditioner is essential during the hot summer months. It isn’t uncommon for the temperature to reach 90 degrees or higher, and without air conditioning, your home can reach 120 degrees, putting your family at risk for heat exhaustion and heatstroke.
If your air conditioner produces warm air, you may need to call a heating and AC repair service in San Antonio, TX. Before making the call, ensure the thermostat is correctly set. It must be set to the cooling mode, and it has to be warmer in the house than the thermostat setting for the unit to kick on. Also, the fan must be set to auto. If it’s on, it will continue running between cycles, and you’ll feel warm air coming from the vents.
If the thermostat is set correctly, it’s time to call a heating and AC repair professional. A few issues can prevent the unit from producing cold air, including:
- The air filter is clogged, preventing adequate airflow and causing the unit to overheat.
- The evaporator coils are frozen.
- The unit leaks refrigerant.
- There’s no power going to the compressor, or it isn’t working correctly.
An HVAC tech can inspect the unit to determine why it isn’t producing cold air and make the necessary repair. The sooner you make the call, the sooner your home will be cool and comfortable again.
#3 Strange Smells
Your HVAC system should produce clean, odorless air, and if you smell something strange when the unit runs, there’s a significant cause for concern. If the unit emits any of the following odors, it’s best to hire a heating and AC repair professional in San Antonio, TX.
- Mold: A moldy smell often indicates mold in the air ducts, and a foul odor in your home is the least of your problems. When the heater or air conditioner runs, mold spores will circulate in the air, which is harmful to your family’s health. Mold exposure causes a variety of health issues, including:
- Burning eyes, nose, and throat
- Skin rashes
- Respiratory issues
- Chronic headaches
- Weakened immune system
- Worsens chronic lung or respiratory conditions
A heating and AC repair professional can inspect the ducts for mold, which can be easily eradicated with an antimicrobial fogger. If the ducts are clear, the mold could be in the air conditioner, which is more challenging to eliminate. If the tech cannot remove every last spore, you’ll need to replace the unit to keep your family safe.
- Rotten eggs: If you smell rotten eggs when the heat runs, turn off the heat immediately, get everyone out of the house, and call 911. The odor indicates a gas leak that can cause an explosion, and the fire department will cut the gas to your home and air out the house, so it’s safe to go back inside.
When the fire department allows you back into your home, you’ll need to call a heating and AC repair service. You’ll need an HVAC tech to repair the leak before the gas service has been restored, and it should be done immediately to prevent your home from getting dangerously cold.
- Burning: If you smell something burning when the heat or air conditioner runs, shut it down immediately and schedule an appointment for emergency heating and AC repair service. The burning smell indicates faulty wiring that can quickly start an electrical fire, destroying your house within minutes.
An HVAC tech can find the damaged wire and fix it before a disaster occurs.
