24/7 Emergency Service

24/7 Emergency Commercial HVAC in Austin, TX


Texas heat does not keep business hours. When a compressor drops at 2 a.m. or a chiller faults over a holiday weekend, you get a live person and a truck rolling — not an answering service taking a message.

Call Now — We Answer


24 hours a day, seven days a week, including holidays. A person picks up, takes the building address and the equipment, and tells you honestly when a technician can be there.

What Counts As An Emergency

When to call after hours instead of waiting


Some failures can wait until Monday. Others compound every hour they go unaddressed, and the cost of waiting exceeds the cost of the after-hours call by a wide margin. The distinction usually comes down to whether the building can operate, whether product or equipment is at risk, and whether the failure is getting worse.

Call immediately if a chiller or central plant is down, if a server room or data closet is losing cooling, if a healthcare or senior living facility has lost conditioning, if you have a refrigerant leak, if there is water coming from a mechanical space or an air handler, or if a freeze event is threatening exposed piping and coils.

If you are not sure, call anyway and describe it. We would rather talk you through something over the phone at no charge than have you sit on a failure that turns into a much larger repair by morning.

Emergency Response

What we handle after hours


Total cooling loss

Rooftop units, split systems and air handlers down in occupied or temperature-sensitive buildings.

Chiller and plant failures

Central plant lockouts and faults, with plant-level technicians rather than a generalist reading a code.

Critical cooling

Server rooms, data closets, healthcare spaces and process cooling where downtime carries a different order of cost.

Refrigerant leaks

Leak response, recovery, repair and the EPA documentation that has to go with it.

Water and condensate

Overflowing pans, failed condensate pumps and leaks from mechanical spaces before they reach the ceiling below.

Freeze events

Hard freeze response for exposed piping, coils, heat trace and make-up air — a real Central Texas failure mode.

When The Fix Takes Time

Temporary cooling and rental coordination


Not every emergency can be permanently resolved that night. A failed compressor on a large machine or a chiller needing a part that is two days out leaves you with a building that still has to operate in the meantime.

We coordinate temporary cooling — spot coolers, portable air handlers and rental chillers with the associated piping and power — so your tenants, your product or your process keeps running while the permanent repair happens on a realistic schedule. Arranging that at 3 a.m. is considerably easier for a contractor who does it regularly than for a facility manager making cold calls.

The buildings that come through failures best are usually the ones already on a maintenance agreement, because we already have the equipment inventory, the access notes and the history before the phone rings.

Where We Work

Serving the Austin metro and Central Texas


Emergency dispatch across the Austin metro. Response times vary with crew location and distance — we will tell you honestly what to expect when you call.

Questions

Frequently asked questions


Do you really answer the phone at night?

Yes — a person, not an answering service taking a message for a callback in the morning. That is a deliberate operating choice, because the entire value of emergency service disappears if the first response is a voicemail. Call and you will get someone who can tell you what to check immediately and when a technician will arrive.

What does emergency HVAC service cost after hours?

After-hours, weekend and holiday work carries a premium rate over standard business hours — that is true of every commercial mechanical contractor and we will tell you the rate on the phone before dispatching. Preventive maintenance agreement customers receive discounted labor including on emergency calls, which is one of the ways an agreement pays for itself.

How fast can you get to my building in an emergency?

It depends on where you are and where crews are at that moment. Inside the Austin metro, expect a truck moving quickly. Outlying areas like San Marcos, New Braunfels or Bastrop take longer, and we will give you a real number rather than an optimistic one. Agreement customers are dispatched ahead of non-contract calls.
