What Is an HVAC Emergency?
Not every HVAC problem requires emergency service, but some situations demand immediate attention.
Heating Emergencies
Call us immediately if:
- Your furnace stops working when temperatures are below freezing
- You have young children, elderly residents, or anyone with health conditions at home
- You smell gas near your furnace or HVAC equipment

- You see sparks or smell electrical burning from your heating system
Why it’s urgent: Prolonged cold exposure creates health risks and can cause frozen pipes that lead to thousands in water damage.

- You have elderly residents, young children, or anyone with heat-sensitive conditions
- Indoor temperatures become dangerously high
- You smell burning or see sparks from your AC unit
Why it’s urgent: Heat exhaustion and heat stroke are real dangers when indoor temperatures soar, especially for vulnerable individuals.

Gas Smell:

Emergency AC Repair
Summer AC failures happen when your system works hardest during heat waves.
Common Emergency AC Problems
Complete System Failure:
- Compressor burnout
