If your HVAC system is experiencing any of the following signs, you should call an emergency heating and AC repair service.
#1 Your Heating System Is Producing Cold Air

Before you make the call, check the pilot and make sure it is lit. Next, make sure there is oil or gas in the tank.

You should also check the setting on your thermostat. Make sure the system is set to the heating mode and that it’s cooler in the house than the setting on the thermostat.

You don’t want to spend money on an unnecessary service call; therefore, you should check your thermostat setting. First, make sure the system is set to the cooling mode. Next, make sure the temperature in your home is warmer than the setting on the thermostat. If everything checks out and your system still isn’t producing cold air, it is time to call a professional.
There are several issues that can cause this problem, and you will need a professional to find the cause.

#3 Reduced Airflow
When your HVAC system is running properly, you should feel a burst of warm or cold air when you stand in front of the vents. If the airflow is weak, your system will need to work harder to heat and cool your home. This extra work can cause your energy bills to increase. In addition, the extra work will put added strain on your system, reducing its maximum lifespan.
There are a few common causes of poor airflow, and it is best to hire an emergency heating and AC repair company to figure out which issue is causing the problem.
- Clogged air ducts: Regardless of how clean your keep your home, dirt, dust, and other debris will end up in your air ducts. When too much debris has built up, it can obstruct the airflow from the vents. Clogged air ducts can also put your family’s health at risk. When your heater or air conditioner is running, the debris will circulate through the air again and again, when can cause your family to develop allergy symptoms. An emergency heating and AC repair service can clean the debris from the air ducts, allowing the heated or cooled air to flow freely.
- Damaged air ducts: Because the air ducts in your home are located under the floors, above the ceiling, and behind the walls, it is impossible to tell if they are damaged. The only way you will know if there is a crack or break in the air ducts is if the airflow from the vents is reduced. An HVAC tech from an emergency heating and AC repair service can inspect the air ducts to find the location of the break and repair it. When the air ducts are sealed up tightly, the heated or cooled air won’t escape, increasing airflow.
- Faulty blower: Your HVAC system’s blower is designed to push the heated or cooled air to the vents. If the blower isn’t working properly, the air won’t reach the air ducts, resulting in poor airflow.
Because poor airflow can affect your home’s temperature, your HVAC system, and your bank account, it is best to call an emergency heating and AC repair service as soon as the problem starts.
#4 Foul Smells
When the HVAC system in your Dallas, TX home is functioning properly, it should produce odorless heated or cooled air. If the system emits a foul smell, you should call an emergency heating and AC service immediately.
The smell coming from the system can help the HVAC tech determine the cause of the problem.
- Mold: It is a serious issue if you smell mold when your heater or air conditioner is running. The air ducts in your home are dark, and the humidity can cause dampness, creating the perfect breeding ground for mold.
If there is mold in the air ducts, mold spores will circulate in the air when your heater or AC is running. Breathing in mold can cause respiratory issues, allergy symptoms and can weaken your immune system, increasing your risk of getting sick. An emergency heating and AC repair service can inspect your ducts for mold. If they find any, an antimicrobial fogger will eliminate the mold and can prevent future mold growth.
- Mildew: If you smell mildew when your heater is running, bacteria are likely built upon the indoor coils. You don’t need to worry if you have a furnace because the internal components heat up enough to kill the bacteria. If you have a heat pump, you should call an emergency heating and AC repair service. They can send a tech to inspect and clean the coils, eradicating the smell and improving the air quality in your home.
- Rotten eggs: If you have a gas furnace and you smell rotten eggs, there is likely a gas leak. You should leave your home immediately and call an emergency heating and AC repair service. A gas leak can result in a fire or an explosion and should never be ignored.
- Burning: A burning smell when your heater or air conditioner is running should not be ignored. The smell could be due to frayed wires or an electrical short, which could spark an electrical fire if you ignore the problem. Your heater’s or air conditioner’s motor could be failing, and the system is overheating. If you smell something burning when your HVAC system is running, you should turn it off immediately and call an emergency heating and AC repair service.
#5 Strange Sounds
Your heater and air conditioner should be relatively quiet when the system is running. It is not uncommon for either system to make a faint clicking sound when kicking on and off.
If either system makes strange sounds, you should call an emergency heating and AC repair service immediately. The sound the system is making can help the HVAC tech find the cause of the problem.
- Banging: A banging sound from the air conditioner or heater is often due to broken or disconnected parts. If your heater makes a banging sound when it starts up, there could be an issue with the ignition.
- Screeching: A screeching sound when the heater is running is often due to a broken metal piece dragging across other pieces of metal. It can also occur when the blower fan is loose. If your air conditioner is making a high-pitched screeching sound, you should turn off the system immediately and call an emergency heating and AC repair service. This sound is due to high pressure, which can be catastrophic if ignored.
- Vibrating: If your air conditioner makes a vibrating noise when it is running, it is often due to a mechanical issue, such as a faulty compressor or motor. If your heater is making a vibrating sound, the heat pump could be on an uneven surface. It can also occur if screws or other parts of the heat pump have come loose.
You should never ignore strange sounds coming from your heater or air conditioner. Ignoring the issue can make the issue worse and can eventually cause a complete shutdown.
It is best to call an emergency heating and AC repair service as soon as you hear strange sounds.
#6 Broken Thermostat
The thermostat in your home tells your HVAC system what to do. The thermostat tells your HVAC system to produce warm or cool air. It also tells your system the temperature you want your home to be. If your thermostat isn’t working, your heater and air conditioner won’t function properly.
There are a few signs that your thermostat isn’t functioning properly:
- Your thermostat is unresponsive, and you have already changed the batteries.
- Your HVAC system cycles on and off frequently.
- Your system shuts down on its own.
- The temperature on the thermostat doesn’t match the temperature in the house.
If you suspect your thermostat isn’t working properly, you should call an emergency heating and AC repair service. A tech can inspect your thermostat to determine if it can and should be repaired, or replacing the thermostat is the better option.
If you have an older thermostat, you may want to consider replacing it with a more modern thermostat that can help save money on your heating and cooling costs.
Programmable thermostats are popular because you can program the temperature in your house to change automatically based on when you are home and when you aren’t.
Wi-fi thermostats are popular because you don’t have to be home to control the thermostat. You can control it using your smartphone or tablet from anywhere in the world, as long as there is an internet connection.
Smart thermostats have increased in popularity over the last few years. They work with your smart devices, such as Google Home or Amazon Alexa. When you are home, you can control the thermostat with the sound of your voice. If you aren’t home, you can use your smart device’s app to control the thermostat.
If an HVAC tech determines that your thermostat needs to be replaced, they can discuss your options and the pros and cons of each.
