Is Your HVAC a Danger to Your Lair?

Not every HVAC problem requires an immediate call, but some issues demand quick action before they escalate. Emergencies are the moments when your system’s failure puts your comfort, safety, or property at risk. Recognizing these situations can help you know when it’s time to summon our mighty crew.

Here are some signs that you have an HVAC emergency on your hands:

• Complete system breakdown during extreme heat or cold – Losing heating or cooling in harsh weather is more than uncomfortable; it can put health at risk and damage sensitive equipment indoors.
• Strange burning smells or electrical issues – Odors of burning or signs of electrical problems can signal fire hazards. These require immediate inspection to protect your property.
• Refrigerant leaks or ice forming on your AC system – Leaks reduce efficiency and can damage the compressor, while ice buildup signals airflow or refrigerant problems that need urgent repairs.
• Loud banging, grinding, or screeching noises – Unusual sounds often mean serious mechanical issues that can lead to full breakdowns if not fixed quickly.
• No airflow or very weak airflow – A sudden loss of circulation can make your system useless, leaving your home or business uncomfortable and unsafe.
• Thermostat failure when the system won’t turn on or off – Without control of your HVAC, you risk energy waste and complete comfort loss.

If you’re facing one of these problems, don’t wait to call Mighty Air right away. We are trained to handle any HVAC emergency and equipped with the tools and knowledge to diagnose and fix the issue quickly. Our technicians are ready to go, and our vans are fully stocked to help day or night.
