When the System Stops, You Need a Team That Answers
No AC in a heat wave. No heat during a freeze. Burning smell or loud noises. We take emergency calls seriously and respond fast.
No Cooling
AC won't turn on, blowing warm air, or completely unresponsive during extreme heat. We prioritize no-cool calls for fast relief.
- AC won't start
- Warm air from vents
- Frozen outdoor unit
- Complete system failure
No Heat
Furnace or heat pump failing during cold weather. No-heat situations can be urgent - especially for families and vulnerable residents.
- Furnace won't ignite
- Cold air from vents
- Pilot light out
- Thermostat unresponsive
Urgent System Failure
Burning smell, loud or unusual noises, sudden airflow loss, or system won't power on. These require immediate professional attention.
- Burning smell
- Loud banging or grinding
- Sudden airflow loss
- System won't power on
Clear Guidance When You're Not Sure What Makes Sense
Not every problem needs a new system - and not every repair is worth the cost. We give you honest answers so you can decide with confidence.
Repair May Be Enough
When the fix makes financial sense
- System is under 10-12 years old
- Issue is minor (capacitor, thermostat, filter)
- Repair cost is significantly less than replacement
- System has been well-maintained
- Energy bills have been reasonable
- You plan to move within a few years
Replacement May Be Worth It
When investing in comfort and savings
- System is 15+ years old or nearing end of life
- Frequent repairs adding up
- Energy bills climbing noticeably
- Inconsistent comfort across rooms
- R-22 refrigerant system (no longer produced)
- Repair cost approaches 30%+ of replacement value
