Real emergency HVAC service means one thing: a licensed technician at your door today — not a callback tomorrow. We keep an on-call tech through the night, every night, and we have parts on the trucks so most emergency calls are solved on the first visit. If you're sweltering, if a new baby is in the house, or if you're managing a vulnerable family member — we move.
What counts as an HVAC emergency
Total no-cool in summer (heat index 95°+)
Compressor failure, tripped breaker, failed contactor, low charge — all fixable fast if a real tech shows up.
Total no-heat in a freeze
Ignitor, flame sensor, gas valve, control board. Never sleep in a house below 55°F — pipes can freeze, vulnerable people can suffer.
Water pouring from indoor unit
Clogged condensate line, rusted pan, or frozen coil. Will cause ceiling damage within hours — call us immediately.
Burning smell from vents
Could be dust burn-off on a new season (normal for 5 minutes) or could be a motor or heat exchanger failure. Shut it off and call.
Strange grinding, screeching, or banging
Compressor or blower motor failure in progress. Running a failing compressor to 'see if it gets worse' will always cost more than stopping it now.
CO alarm activating
Shut off gas appliances, ventilate the house, get everyone outside, and call us — we'll diagnose free and recommend next steps.
Our process — four steps, zero surprises
- Book in two minutes. Online or by phone. Confirmation within the hour.
- Text when we're rolling. Tech photo, live ETA, and a real window — not a 4-hour guess.
- Diagnose and quote flat. We walk you through what we found, show you the part, and quote in writing. Nothing starts without a yes.
- Fix it and back it up. Most repairs done in one visit. Every job carries a workmanship guarantee.
What does 24/7 emergency HVAC cost?
After-hours service fee is $89 (waived if we make the repair). Repair pricing is the same flat rate we charge during business hours — Care Club members skip the service fee entirely.
