How Do I Know When I Need HVAC Emergency Services?

Many people are unsure whether or not their HVAC system’s issue is an emergency. This can result in them hesitating to act, leading to the situation worsening and their home becoming either too hot or too cold. If you are wondering what situations fall under the category of HVAC emergency, here are a few ways you can tell:

Assess the Situation

HVAC emergencies often have the following signs:

  • Your heater’s heating ability has greatly decreased or has stopped altogether.
  • Your heater or air conditioner seems to be losing electrical power or keeps tripping the breaker.
  • There is a water leak near your HVAC unit.
  • There is an unusual odor such as rotten eggs or the smell of something burning.
  • Your HVAC unit is making unusual sounds.

If you notice any of the above signs, immediately shut down your HVAC unit. This will prevent the damage from worsening and may save your unit from overall failure. Next, contact your trusted HVAC specialist. 

However, if you notice immediate danger such as the smell of rotten eggs or smoke coming from your unit, evacuate immediately. This could indicate a gas leak or a fire starting within your unit. Once you are safely outside, contact your trusted HVAC technician.

What Are Some Common HVAC Emergencies?

There are many different issues your HVAC system can face in the course of its lifetime. However, these are the most common emergency HVAC issues:

Clogged Condensate Lines

HVAC system leaks are one of the most common issues our team sees. A clogged condensate line usually causes these leaks. Your HVAC system’s condensate line collects excess moisture and directs it away from your HVAC system outside of your home. This prevents damage to your unit.

Over time, the condensate line can become clogged due to dirt and grime buildup. When this happens, the water cannot leave the system properly and begins to pool up. These leaks are usually small but can lead to water damage and serious issues with your HVAC unit if not handled properly and in a timely manner.

Invest in routine maintenance to prevent this issue. Our HVAC technicians will check and clean the condensate line to keep a clog from happening.

Frozen Coils in Your AC Unit

Air conditioners run refrigerant through the coils to cool the home. During the summer, when the air conditioner is running constantly, the refrigerant temperature can become too cold. This generally happens when one of the following occurs:

  • Running the A/C when it’s below 60 degrees outside
  • Running the A/C temperature too low
  • The airflow becomes blocked
  • The refrigerant is leaking

It is recommended that homeowners set their air conditioner at 70 degrees or higher.

Blown Fuses or Tripped Breakers

If the blower in your HVAC system becomes overworked, it can lead to a blown fuse and possibly trip your circuit breaker. The most common cause of an overworked blower is a dirty air filter. A dirty air filter can lead to the airflow being blocked, putting major stress on your unit.

To avoid this issue, get your HVAC unit serviced at least twice a year to have the air filter checked.

Your Furnace Is Malfunctioning

Furnace issues can be the result of a variety of factors. From a malfunctioning thermostat to a cracked heat exchanger, these issues can result in your heater working poorly, leaving your home cold.

Here are the most common signs that your furnace is encountering an issue:

  • Scraping sounds or other strange sounds coming from the furnace: usually a sign that the ball bearings or belts may be failing.
  • The pilot light is flickering yellow: a sign of excess carbon monoxide.
  • The unit is having a problem starting up: generally means there is disconnected wiring or a damaged thermostat.
  • Inadequate heat in the home: usually the sign of a leaking air duct.
