Polar Express HVAC & Refrigeration

24/7 Air Conditioning

No cooling at midnight? The phone still gets answered.

Polar Express provides emergency AC repair for homes across the San Antonio metro, with 24/7 emergency dispatch and same-day service on most repair calls. One flat-rate price is approved in writing before work begins for no-cool systems, breaker faults, iced coils, and drain overflows. TDLR license TACLA00127982C.

Before anyone talks about dispatch, you get the three checks worth doing right now. Two of them end the call often enough that we ask everybody to try.

An air conditioner picks the worst possible moment to quit because the worst possible moment is when it is working hardest. A San Antonio house with no cooling in July does not stay comfortable for long, and it becomes genuinely unsafe for infants, older adults, and anyone with a health condition well before it becomes unbearable for everyone else. Polar Express answers the phone around the clock, every day of the year. The first thing you get is not a dispatch window. It is a short list of things to check while you are standing there, because a tripped breaker, a filter packed solid, and a full condensate pan account for a real share of the calls that come in after dark, and any of the three can be settled in five minutes without a technician.

What we handle

Emergency AC Repair covers more than one failure.

The complaint that gets called in is rarely the whole job. These are the things a technician is actually looking at on this equipment.

  • No cooling, at any hour

    Nights, weekends, and holidays. The line is staffed year round, and a person answers it rather than a menu tree with a callback promise attached.

  • Heat that has become a safety problem

    Households with infants, older adults, or someone managing a medical condition move up the queue. Say so on the call, because we cannot prioritize what nobody tells us.

  • Breakers, disconnects, and dead systems

    A system with no power at all, a breaker that will not stay set, or a burning smell coming from an air handler. That last one is a shut-it-off-right-now call.

  • Overflowing drains and water damage

    A condensate pan spilling into an attic does damage every hour it continues, and the float switch that stopped the system is not the thing that needs fixing.

  • Systems iced solid overnight

    A coil frozen into a block will not cool anything until it thaws, and we walk you through starting that thaw before a truck has left the shop.

Signs and causes

What you are seeing, and what usually causes it.

Read these before you call. Knowing which one matches gets the right parts on the truck, and a couple of them are worth acting on in the next ten minutes.

  • The house is climbing and will not stop

    A home several degrees over setpoint and still rising in the evening, while the outdoor load is falling, is not going to recover on its own overnight. That is a call to make now rather than in the morning.

  • The breaker keeps tripping

    A breaker is a safety device doing its job, and resetting it repeatedly is asking it to stop. Set it once. If it goes again, leave it off and call, because the fault is electrical and every reset is another chance for it to become a fire instead of a repair.

  • Burning smell, buzzing, or smoke from the equipment

    Shut the system down at the thermostat and at the breaker, then call. Nothing in that combination improves while you wait, and the distance between a scorched contactor and an actual fire is often measured in minutes.

  • Water is coming through the ceiling

    Turn the system off so the coil stops producing condensate, put a container under the drip, and call. The unit will not cool while it is off, and the drywall gets more expensive for every hour it stays on.

  • Somebody in the house cannot tolerate the heat

    Heat is a medical issue before it is a comfort issue for infants, older adults, pregnant women, and people taking certain medications. If that describes your household, lead with it in the first sentence of the call and we will treat it accordingly.

What it costs

You approve the price before the work starts.

After-hours dispatch is priced differently from a Tuesday morning appointment, and you hear that on the phone rather than discovering it on an invoice. Everything else works exactly the way it always does. The technician diagnoses the system, tells you what failed, and gives you one flat-rate price to approve before anything is opened up. And if it is clear from the call that nothing is at risk and the system will keep limping along until morning, we will tell you the cheaper move is to wait. That happens more often than you would expect from a company that bills for night calls.

What moves the number

  • What time it is, because an overnight or holiday call does not carry a weekday appointment rate
  • What actually failed, and whether that part is on the truck at two in the morning
  • Whether the visit ends in a full repair or a temporary measure until the supply houses open
  • Access to the equipment, particularly an attic unit in the middle of the night
  • Whether a second system at the same address gets looked at on the same trip
  • Any follow-up work agreed once the immediate problem is under control

How the job runs

What happens between your call and a working system.

  1. Step 1

    A person picks up

    A human voice, at any hour, rather than a recording. You get asked what the thermostat reads, what the house actually feels like, whether the outdoor unit is running, and who lives there, because those answers set your place in the queue.

  2. Step 2

    Three checks before we roll

    Breaker and disconnect, air filter, and the condensate float switch. We stay on the line while you look, and a meaningful share of after-hours calls end right there with nothing owed to anybody.

  3. Step 3

    Dispatch with the truck loaded

    Whatever you described decides what rides along. Capacitors, contactors, motors, and control boards are standard stock, so most night calls close without needing a second visit.

  4. Step 4

    Repair now, or stabilize and return

    When a permanent fix needs a part that no supply house will hand over until morning, you get the honest version of that, plus whatever we can do to make the house livable until we are back.

Questions

Straight answers, before you call.

Call (210) 376-0781

No cooling in the middle of a Texas summer counts, especially where infants, older adults, or anyone with a health condition lives in the house. So does a breaker that keeps tripping, a burning smell from the equipment, water coming through a ceiling, and a temperature that is climbing and will not level off. If you are unsure, describe it on the phone. Talking it through takes a minute and costs nothing.

Three things, in order. Find the breaker for the air conditioner and confirm it has not tripped, then check the outdoor disconnect beside the condenser. Pull the air filter and hold it up to a light, because a blocked filter is what freezes coils. Then look at the condensate pan and the small float switch on the drain line, since a full pan shuts the system down deliberately. Any of the three can end the call right there.

Yes, after-hours dispatch carries a different rate than a scheduled appointment, and you hear those terms before a truck moves. The flat-rate rule itself does not change with the hour: the repair is quoted and approved by you before work begins. Nothing is billed hourly, and the number does not grow because the job ran on into sunrise.

Close blinds and curtains on every window the sun is hitting, run ceiling fans only in rooms people are actually in, and stop using the oven, the dryer, and anything else that adds heat indoors. Move everyone to the lowest floor, drink more water than feels necessary, and open the house up only once the outdoor air has genuinely dropped below the indoor temperature. If anyone shows signs of heat illness, that is a 911 call rather than an HVAC call.

Yes. The Polar Express emergency line is staffed every day of the year, weekends and major holidays included, and technicians are dispatched on genuine no-cool calls those days the same as any other. Office hours govern scheduled appointments and estimates, not emergencies. The number that reaches a person at any hour is (210) 376-0781.

Polar Express dispatches emergency AC technicians 24/7 across San Antonio, with same-day service on most repair calls. The dispatcher gives a real arrival window by phone; windows follow the active route and household safety, not a fixed guarantee.

Polar Express repairs all major air conditioner brands after hours across San Antonio, including central split systems and their thermostats, air handlers, and outdoor units. Emergency diagnosis follows the fault rather than the logo, and common capacitors, contactors, motors, and control components are considered when the truck is prepared for dispatch.
