Our skilful and courteous Dallas service professionals are available 24/7 to help you and your family when the heat goes out, you smell sulphur in your home, or the AC won’t turn on. Continue reading to learn seven signs that you need our Dallas emergency HVAC services:
1. Your Home is Filled with a Bad Smell
Do you smell rotten eggs in your home? This smell means you have a gas leak in your home. Since natural gas is typically odorless, utility companies and fuel providers put sulphur into the natural gas so that if it leaks Dallas homeowners will smell the issue.
Gas leaks are very serious. If you smell rotten eggs, you might have a gas leak that could cause a devastating fire or explosion. When this happens, open your windows immediately and call our Dallas emergency HVAC service professionals right away. We can be reached.
2. You Hear Strange Noises in Your Furnace
Do you hear banging, popping, thumping, or knocking noises from your furnace? It’s time to call a Dallas furnace repair and service professional. Scraping noises might mean that part of your furnace has come loose, such as your blower wheel, and need to be fixed by a professional right away.
A high-pitched squealing noise could indicate that part of your furnace has worn out and needs to be replaced. Often, this noise is caused by a malfunctioning blower fan motor. This issue will require emergency furnace repairs.
A loud pop or banging noise when the furnace turns on could mean you have a dirty furnace burner. When dirt builds-up on your furnace’s burners, it can cause problems with the ignition—which can cause gas to build-up. The popping noise you hear is the byproduct of a small explosion. These explosions can cause serious damage to your furnace. Call one of our 24-hour furnace repair and service professionals right away if you hear a banging noise coming from your furnace.
3. Cold Air is Blowing Out of Your Furnace
When you’re relying on your furnace to keep you warm during a chilly Texan night, the absolute last thing you want is for it to blow out cold air instead of warm air. Typically, if your furnace is blowing out cool air when it should be warming up your home, a dirty air filter is the cause. The dirty filter blocks airflow from your furnace’s heat exchanger and causes the furnace to overheat. When your furnace overheats, it trips its high limit switch. This switch essentially tells the furnace burners to turn off so that the heat exchanger does not crack. While this safety protocol is helpful to prevent serious damage to your furnace, it’s also a sign that you might need Dallas emergency HVAC services in case your furnace has started to deteriorate.
4. Your AC Unit is Blowing Less Air Through Your Vents
Have you noticed a reduction in the cool air blowing through your vents when you use your air conditioning unit? Generally, this means that your AC unit does not have access to unrestricted airflow; and, this usually happens for one of two reasons. Your Dallas emergency HVAC service professional will be able to correctly diagnose the situation for you.
The first reason why your AC unit may not be blowing out enough air is because of a clogged or dirty air filter. When an air filter becomes clogged with dirt, debris, or dust, it inhibits your air conditioning unit’s ability to circulate air through your home. Moreover, dirty air filters further complicate matters by failing to purify the air you and your loved ones are breathing.
The second reason why you may require emergency air conditioner repair due to a lack of airflow is because an animal has gotten trapped or built a nest in your vent. From time to time, rodents or birds may find themselves in your air vents. While these little critters may think your vents are an ideal place for a nest, the materials used to build a nest could block the air vents and restrict airflow.
5. Your AC Unit is Blowing Out Warm Air
Just like how you rely on your furnace to keep you warm, you rely on your AC to keep you cool. When your AC unit starts blowing out warm air, it’s time to call for emergency HVAC services. Likely, the reason your AC unit has started blowing out warm air is because its coolant levels are low and the machine is not able to undergo the chemical reaction that creates cool air. However, your air conditioning unit might also be blowing out hot air because there is a coolant leak, an issue with the compressor, or there is an issue with your return duct. Whatever the case may be, you’ll require emergency AC repair to get your unit back up and running.
6. Your AC Unit Only Runs in Short Spurts
Having your AC unit only work for short periods of time—or turning off and on again seemingly at random intervals throughout the day—can be immensely frustrating. Especially if you have pets, small children, or an elderly person living in your home. You rely on your air conditioning not only to keep everyone cool during a hot Texan day, but also safe. There can be many reasons why your AC might only be working for short periods of time, including:
- 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 Dallas emergency HVAC service professionals will be able to help you figure out why your AC is not working and make the repairs right away. Our top priority is keeping you and your loved ones comfortable and safe.
7. Issues with Your Thermostat
If you find that every time you turn the thermostat on to warm up your home and the furnace does not activate, or you need to cool down but the AC won’t start, there is likely an issue with the electrical connection in your thermostat. If you noticed damaged or frayed wires near your AC unit, furnace, or thermostat, turn your electricity off and call for a Dallas emergency HVAC service immediately.
