5 Signs You Need Emergency HVAC Services

It’s important to pay close attention to the operation of your heating and cooling systems. Your systems will show signs that they need immediate attention from a certified and insured HVAC technician. If you detect any of these issues, we recommend requesting emergency HVAC service without delay:

  • Leaks: Refrigerant and water leaks require immediate attention. These can cause serious damage to your system and can expose you to toxic coolant, etc.
  • Frequently tripped breaker: Frequently tripped breakers can indicate clogged air filters or dirt buildup in the unit. They can also point to more critical issues such as a faulty circuit breaker or a short within the motor.
  • Rotten egg odors: If you have a natural gas furnace and detect rotten egg odors, it’s a critical emergency that indicates a natural gas leak.
  • Short-cycling: If your furnace is short cycling, it can indicate a problem with the fan limiter. It’s also possible it’s due to a CO or gas leak, flue limiter, faulty thermostat, or dirty flame sensor.
  • Odd noises: Grinding, banging, clanking, screeching, etc. within your furnace or AC often indicates critical component failure. These noises require prompt investigation and repair, otherwise the damaged component can spread damage throughout your system, which increases the cost and complexity of the repairs.

Frequently Asked Questions

Should I shut down a malfunctioning furnace or air conditioner?

If you suspect a malfunction, it’s best to shut the system down until a qualified HVAC technician can assess the condition of the unit and identify the cause of the issue.

How often should I schedule HVAC maintenance?

It’s best to schedule heating system maintenance in the fall, and cooling system maintenance in the spring.
