24/7 Commercial
HVAC Emergency
A commercial HVAC failure shuts down sales, sends staff home, and threatens product. Jupitair runs a live after-hours line for North Texas businesses with a 2-hour response target on critical breakdowns — so you stay open.

A Commercial Failure Isn't a Home AC Call
Rooftop units, three-phase power, and economizers behave nothing like a residential split system. When a packaged unit drops on a 100-degree afternoon, you need a tech who works on commercial equipment every week — and the parts to fix it on the first trip.
After-Hours & Weekends
A live line at night, on weekends, and on holidays — when a rooftop unit quits, it rarely happens at 10 a.m. on a Tuesday
2-Hour Response Target
A 2-hour response target for critical breakdowns across our Plano, Frisco, and Addison commercial zones
Keep the Doors Open
Temporary spot cooling and stocked truck parts so you stay open while we diagnose, source, and repair
Commercial-Grade Techs
TDLR-licensed techs who work on 3-25 ton rooftop units, three-phase power, and economizers — not just home AC
The Breakdowns We Get Called On Most
We triage by real-world impact: anything that stops sales, threatens product, or floods a space jumps to the front of the line.
Rooftop Unit Down
CriticalAn RTU tripping on high-pressure or refusing to start — no cooling to the floor below it
Refrigerant Leak / No Cooling
CriticalR-410A or R-454B loss leaving a packaged unit blowing warm air during a Texas afternoon
Tripped Breaker / Three-Phase Fault
HighA failed contactor, blown capacitor, or lost leg of three-phase power killing a unit
Condensate Overflow
HighA clogged drain pan flooding a drop ceiling or staining product below — water damage in progress
Compressor or Blower Failure
MediumHard-starting, grinding, or a seized blower motor stopping airflow to the space
Thermostat / Controls Lockout
MediumA controller fault or sensor failure leaving the space stuck warm or cold
The Real Cost of Downtime
A retail store that loses cooling on a Saturday watches customers leave. A restaurant kitchen without makeup air can be forced to close. Our job is to compress the window between your call and a working system — and to keep you running while we do it.
Stay Open With Spot Cooling
Portable spot coolers bridge the gap while a part ships, so you don't have to lock the doors
Protect Product & Inventory
Temperature- and humidity-sensitive stock and a flooding drain pan can't wait until Monday
Stop the Damage From Spreading
A hard-starting compressor or overflowing pan left running turns a small repair into a unit replacement
Businesses We Serve 24/7
What counts as an emergency? Any failure that stops business, threatens product, or risks property — no cooling on the floor, a flooding pan, or a dead rooftop unit. Want to avoid the after-hours call entirely? A commercial preventive maintenance plan catches most of these before they shut you down.
How We Triage a Commercial Breakdown
Not every call is equally urgent, and we sort them by financial and safety impact rather than first-come, first-served. The order generally looks like this:
- Food service — kitchen makeup-air and exhaust failures. Without makeup air, the hood can't pull and the line shuts down; refrigeration-adjacent comfort cooling protects product and keeps the kitchen working.
- Medical and dental offices — patient comfort isn't optional, and some supplies and medications need a stable temperature.
- Server closets and IT rooms — a small office still has a rack that overheats fast once cooling drops.
- Retail stores — every hour without cooling during a North Texas summer is walked-away revenue.
- Office and professional suites — comfort, productivity, and the cost of sending staff home.
Most of these come down to a handful of failure points on a rooftop unit: a failed run capacitor or contactor, a tripped high-pressure switch from a dirty condenser coil, a refrigerant leak in R-410A (or newer R-454B) systems, a seized blower motor, or a clogged condensate drain backing up into a drop ceiling. Because these parts are predictable, we stock the common ones on the truck and finish many repairs on the first visit.
Pricing is disclosed before we start. The after-hours diagnostic runs $149-$249, and a flat $250 after-hours surcharge applies to calls outside our 7 a.m.-7 p.m. window. If a unit needs a part we don't carry, we'll set you up with portable spot cooling so you can stay open while it ships. When the fix is a band-aid on a 15-year-old unit that keeps failing, we'll be straight with you about whether a rooftop unit replacement or a new system design is the smarter spend.
We run this emergency line across all eight North Texas cities we serve — including our core Plano, Frisco, and Addison commercial zones — within Jupitair's 20-mile service radius. And the cheapest emergency is the one that never happens: a quarterly maintenance plan catches weak capacitors, dirty coils, and clogging drains before they strand you on a holiday weekend.
