Your HVAC system works hard to keep your home or business comfortable—especially during Texas heatwaves or unexpected cold snaps. But when something goes wrong, delays in repair can quickly turn a small issue into a major problem.

At Tarrant Mechanical, we offer 24/7 emergency HVAC repair services for residential, commercial, and industrial clients. Here’s how to know when it’s time to call in the professionals right away.

1. No Airflow or No Heating/Cooling

If your HVAC system is running but there’s no air coming from the vents—or it’s blowing the wrong temperature—it’s a red flag. This could be caused by:

  • A failed compressor
  • Blower motor issues
  • Refrigerant problems
  • Electrical failure

Sudden loss of airflow can mean your system is at risk of total failure and needs emergency HVAC repair.

2. Strange Noises or Smells

Your system should run quietly in the background. If you notice banging, screeching, hissing, or burning smells, stop using the system immediately and call for service.

  • Banging = loose or broken parts
  • Hissing = refrigerant leak
  • Burning smell = potential electrical issue or overheating motor

These are serious warning signs that should never be ignored.

3. HVAC System Won’t Turn On

If your system won’t start at all—even after checking the thermostat, breaker, or reset switch—you’re likely dealing with a deeper issue like:

  • A failed capacitor or motor
  • A wiring problem
  • Thermostat malfunction

Tarrant Mechanical responds fast to diagnose and fix issues before conditions get worse.

4. Rapid Cycling or Constant Running

If your HVAC system turns on and off too frequently or runs constantly without reaching the set temperature, this could signal:

  • A malfunctioning thermostat
  • Clogged filters
  • Faulty sensors
  • Low refrigerant levels

Not only is this inefficient, but it can damage components over time and increase energy bills.

5. Water or Refrigerant Leaks

Pooled water around your unit or visible refrigerant leaks are definite emergency signs. These issues can lead to:

  • Property damage
  • Mold growth
  • Complete system failure

Shut off the system and call Tarrant Mechanical immediately to prevent further complications.
