4 Signs You Need Emergency HVAC Assessment

Posted on

Most HVAC issues don't require immediate attention. However, certain situations can benefit from an emergency HVAC consultation for safety and building code adherence. How can you tell if your HVAC issue can wait or if you should call someone right away? Look for these four signs that you need an emergency HVAC assessment. 

Refrigerant Leak

Refrigerants emit toxins into the air. When a refrigerant leak occurs in your HVAC system, the people in the area risk breathing the material into their lungs. You may notice the leak itself as a pool of liquid near the unit. Alternatively, you may notice ice developing on the unit, which is another sign of a leak. Don't attempt to handle the leak yourself. Hire a professional to handle the job safely.

No Cold Air

There are two main issues you may have with your air conditioner: no power or blowing warm air. If the unit is blowing warm air, there may be an issue with one of the interior components of the system. If the unit doesn't have any power, check for damage to the cord (and that the cord is plugged in). If a reset at the circuit breaker doesn't resolve the issue, you will need to have a tech diagnose and resolve the electrical problem.

Strange Odors 

Many HVAC units include gas units, such as boilers or furnaces. In the case of a gas leak, you may notice gas smells coming from your furnace. While gas doesn't naturally emit an odor, companies add a potent chemical (hydrogen sulfide) for safety reasons. In the case that you smell gas, turn off the unit and evacuate the building immediately. Gas is not only dangerous to breathe, but it's also highly flammable. Treat the issue immediately.

Loud Noises

No AC unit will run silently. However, they shouldn't produce so many sounds that it becomes a distraction. A hissing sound, the most alarming noise, typically indicates a refrigerant leak. Additionally, you may notice clanking noises, which indicate loose pieces inside the unit banging into each other. While not an immediate problem, the rogue interior parts will quickly lead to a malfunctioning unit.

Whether talking about a residential AC unit or a complex commercial HVAC system that provides comfort to thousands of people every day, you need to take all four of these issues seriously. Do not attempt to handle the repairs yourself unless you have the proper licenses. Call a professional to learn more about circumstances that require an emergency HVAC consultation
