What is an HVAC emergency?

What Is an HVAC Emergency?

Not every HVAC problem needs emergency service, but some symptoms should be taken seriously. Call Mighty Air if you're dealing with:

Complete loss of cooling

During extreme heat.

Complete loss of heat

During cold weather.

Burning or electrical odors

Turn the system off if it's safe to do so.

Repeated breaker trips

If it trips again, don't keep resetting it.

Water leaking around HVAC equipment

Leaks can damage floors, ceilings and walls quickly.

Loud grinding, banging or screeching

Sudden mechanical noise usually means something has failed.

A system that keeps starting and shutting down

Repeated restarts can strain the equipment.

A failure affecting vulnerable people

Young children, older adults, or anyone with health concerns.

Safety first

Safety First

  • Burning smell or an electrical hazard? Turn the HVAC system off if it is safe to do so.
  • Smoke or fire? Leave the area and call 911.
  • Gas smell or a carbon monoxide concern? Leave the area and contact your gas utility or emergency services. Don't troubleshoot the equipment yourself.
Quick checks before you call

Quick Checks Before You Call

If the system still won't run after these checks, turn it off and call us. Don't open electrical panels or attempt internal HVAC repairs yourself.

1

Thermostat

Make sure it has power and is set correctly for heating or cooling.

2

Air filter

Check for a filter that is severely clogged.

3

Breaker

Check whether the HVAC breaker has tripped. If it trips again, don't keep resetting it.

We diagnose before recommending repairs

An Emergency Visit Doesn't Mean a New System.

Many sudden breakdowns come down to a single failed part. Our technicians diagnose the system, find the actual cause, explain what we found, and walk you through your repair or replacement options before any work begins.

Emergency Cooling Problems

A sudden AC failure gets uncomfortable fast in Jacksonville's heat and humidity. If your air conditioner or heat pump stops cooling, loses airflow, trips breakers, or leaks water, see our AC Repair page for more on urgent cooling problems.

Emergency Heating Problems

Heating emergencies are less common in Northeast Florida, but a complete loss of heat can still be urgent when temperatures drop. Most homes here heat with a heat pump, and Mighty Air diagnoses heat pumps, auxiliary heat, thermostats, and controls.
