5 Problems to Call Emergency HVAC Repair For
Normally, the HVAC system in your home is a silent workhorse, out of sight and out of mind as it toils away at its critical job. During the winter and summer months, when the weather is at its most extreme, the service that your HVAC system provides can be lifesaving.
Occasionally, your HVAC system will require maintenance. In most cases, this maintenance is routine and can be scheduled ahead of time and taken care of at your convenience. However, certain problems with your heating and air conditioning should be considered emergencies and dealt with immediately. Many companies, including Entek, provide 24/7 emergency HVAC repair when necessary.
Telling the difference between a non-critical repair that can wait for a convenient time and an emergency isn’t always as simple as it sounds. Below, we’ve illustrated five examples of problems you should call emergency HVAC repair for:
1. If the Thermostat Breaks
On the face of it, a broken thermostat doesn’t sound like that serious of a problem. The thermostat is a small, relatively simple piece of equipment that won’t release any dangerous chemicals or pose a fire hazard if it stops working. Even so, a thermostat ceasing to function should be considered an emergency because your entire HVAC system is dependent upon it.
Think about it: your HVAC system utilizes the thermostat to decide when to turn on (and off). If it fails to correctly monitor the temperature, it may not turn on when it’s supposed to, which can be dangerous during the coldest and hottest days of the year. Or it’s possible that the system may not cycle off when it’s supposed to, forcing it to stay on even when it’s no longer needed. If that happens, it will put undue wear and tear on your HVAC system as well as drive your energy bill way up.
If you note any of the signs mentioned above, such as an HVAC system that refuses to turn on, one that runs continuously, or one that simply fails to respond to any changes you make in the temperature settings, a faulty thermostat could be the culprit, and you should contact your HVAC professional immediately.
2. There Is No Airflow in the House
Most HVAC systems operate using a large fan to deliver air throughout the home by way of a series of ducts. These ducts lead to vents through which the air flows, heating up or cooling down the home, depending on your needs at the time. Sometimes, you may notice that, despite the fact that your heater or air conditioner seems to be working hard, the temperature doesn’t noticeably change. Placing your hand in front of the vent can often reveal the problem: the airflow in the house has either been reduced dramatically or stopped completely.
There are several reasons why the airflow through the ducts in your home might become restricted. It could simply be that the filters have become too clogged with dust and dirt and need to be replaced. Or maybe the capacitor in your AC unit has malfunctioned. It could be a result of blockage caused by ice forming around the condensers. Whatever the cause, this issue should be considered an emergency and be brought to the attention of your HVAC professional, as it can lead to safety issues, including fire hazards and the possibility of toxic gases building up.
3. Gas or Refrigerant Leak
Most HVAC systems are made up of two separate but equally complex and important systems: the air conditioner and the furnace. Some advanced modern HVAC systems combine both of these into one unit, but odds are your heating and cooling are performed by separate machinery. Air conditioners cool air by utilizing condensers that contain a refrigerant. Heaters warm the air by burning a fuel source to generate heat. The burning of coal, oil, wood, or other fuels generates toxic gases such as carbon monoxide as a byproduct, which must be vented outside of the home safely.
If any part of your HVAC system begins to leak—whether it’s refrigerant dripping from the air conditioner’s condenser coils or gas seeping through a hole in a pipe or vent—you should contact your emergency HVAC repair immediately. This is especially true in the case of a gas leak, which can pose a life-threatening hazard. If your home’s carbon monoxide detectors or other alarms are going off, vacate the house until you are cleared to return by an HVAC professional.
4. You Hear Strange Noises From the HVAC System
One sure way to tell if your HVAC system is malfunctioning is if you hear a strange noise coming from it. Even if the system itself appears to be operating just fine, noises such as loud buzzing, high-pitched squealing, low rumbling, and other unusual sounds may be indicators of a serious problem.
In some cases, the problem may be a relatively easy fix for your HVAC professional. Older air conditioners might experience a slipped belt, which can announce itself with a high-pitched squeal. In most cases, your emergency HVAC repair professional can address this problem without too much difficulty. Other problems may be more difficult to address, such as a malfunctioning compressor, which can create a loud buzzing sound. Regardless, if your HVAC system starts making strange noises, it’s time to call a professional.
5. You Smell Something Burning
Another problem that can indicate something quite severe is a burning smell emanating from your HVAC system. Needless to say, if something in your heating system or air conditioning is burning, that’s an emergency and should be addressed immediately before the problem becomes a true hazard. It could be an electrical issue or the cause could be friction caused by one of your HVAC unit’s mechanical systems.
If you smell anything burning, immediately turn off your HVAC system and call your emergency HVAC repair professional. Remember, companies like Entek are on call 24 hours a day to keep you and your family safe when you experience an HVAC emergency.
