Our friendly and experienced Rockwall HVAC experts are at your disposal 24/7 to ensure you and your family are safe when the furnace breaks or when you smell sulfur in your home, or when the AC won’t turn on.
Unsure when you might need emergency HVAC services? Whether for emergency furnace repair or emergency AC repair, keep reading to learn five signs to look out for:
1. You Smell Rotten Eggs
Do you smell sulfur at home in Rockwall? This means you have a gas leak. Since natural gas is typically odorless—and very dangerous—utility companies and fuel providers put sulfur into the natural gas. That way, if it leaks, then homeowners will immediately know there is a problem.
Gas leaks are dangerous. If the smell of rotten eggs is wafting through the ducts, you might have a gas leak. It’s extremely combustible, so we recommend opening all your windows immediately, shutting off your HVAC system, and calling our Rockwall emergency HVAC service experts right away.
2. You Hear Strange Noises in Your Furnace
If you hear banging, popping, thumping, or knocking noises in your furnace, you should call an emergency furnace repair expert.
Scraping noises generally mean that one of the parts in your furnace has come loose. This could include the blower wheel or belt. A professional will need to repair the part right away.
A high-pitched squealing noise typically means that areas of your furnace have worn out. The worn out parts will need to be replaced. More often than not, a malfunctioning blower motor is the culprit of this noise. To repair the motor and replace worn out parts will require the help of an HVAC emergency service technician.
Lastly, loud banging noises coming from the furnace could mean you have a dirty burner. While that may not sound too serious, dirt buildup can actually cause ignition problems. This causes gas to build-up in the furnace. The resulting popping noises are the result of small explosions taking place within the furnace. These small explosions are dangerous and can damage your furnace. It’s best to call one of our emergency repair experts right away.
3. Cold Air is Blowing Out of Furnace
Rockwall winters have become unpredictably colder than usual, and when you’re counting on your furnace to keep you and your loved ones warm, the last thing you want is for it to blow out cold air. Generally, if your furnace is blowing out cool air instead of warming up your home in Rockwall, the problem is a dirty air filter. What is happening is that the dirty air filter is blocking airflow from your furnace’s heat exchanger. This causes the furnace to overheat and consequently trips the machine’s high limit switch. The role of the high limit switch is to notify the furnace burners to turn off, so the heat exchanger does not crack. This safety protocol is intended to prevent serious damage to your furnace. However, it’s also a sign that you need Rockwall emergency HVAC services.
4. Your AC Unit is Not Blowing Enough Air Through Your Vents
Do you feel like your AC unit is working at full capacity, but very little cool air is coming out? Typically, this indicates that your AC system may have an obstruction that’s restricting air flow. This issue is generally caused by two issues that your local emergency HVAC technician will be able to diagnose.
The first reason why you may require emergency AC repair is because the unit is not blowing out enough air due to a clogged filter. When an air filter becomes clogged with dirt or debris, it can block your AC unit’s ability to circulate air through your Rockwall home. Likewise, if you have dirty air filters your home’s air is not being purified.
The second reason why you may require Rockwall emergency HVAC services due to a restricted airflow is because a wild animal may have settled inside your vent. Seeking a cozy home, rodents or birds may find themselves trapped in your air vents. While these little creatures look at your vents like the perfect place to build a new home, the materials used to build a nest, like twigs, grass, and other debris, could block the air vents and restrict airflow.
5. Your AC Unit is Blowing Out Warm Air
Just like how you count on your heating to keep you warm in the winter, you rely on your AC to keep you cool in the summer. Your AC unit is not supposed to blow out warm air. If it is, then it’s time to call for Rockwall emergency HVAC services. The primary reason your air conditioning unit has started to blow warm air is because its coolant levels are too low. When an AC unit’s coolant levels are too low, the machine can’t undergo the chemical reaction that creates cool air.
Sometimes air conditioning units blow out warm air for the following reasons as well:
- An issue with the compressor
- A coolant leak
- An issue with the outside utility
- An issue with the return duct
If your AC is older and has already had multiple costly repairs, it might be more cost-effective to get a more energy efficient air conditioning replacement for energy cost saving purposes and reliable performance.
6. Your AC Unit Only Runs Short Cycles
Does your air conditioning unit only work for short periods of time? Does it turn off and on again at random throughout the day? Not only can this spotty performance be very frustrating, it can also be dangerous. If you have animals, kids, or an elderly family member living in your Rockwall home, you need to be able to trust that your AC unit is going to work properly to keep your loved ones comfortable and safe.
An emergency AC repair technician will be able to tell you why your AC keeps turning on and off again. A few reasons could include:
- Low coolant levels in the unit
- Your thermostat is set too low
- Your cooling coils have frozen
- Your water drain line is clogged
One of our Rockwall emergency HVAC service experts will be able to get your air conditioning unit working correctly again. Our company’s first priority is your safety and comfort.
7. Issues with Your Thermostat
Does your furnace and/or AC unit fail to respond to your thermostat settings? If you find that every time you try to warm-up your home in Rockwall and nothing happens, or you want to cool-down and the AC won’t kick in, you probably have an issue with the thermostat itself. This is likely an electrical problem. If you’ve noticed frayed wires near your AC unit or thermostat, you likely have electrical connection issues. Turn your power off right away and call a Rockwall emergency HVAC service technician.
