Hard freezes do not come often to the Valley, but when they do, heating equipment that has sat idle for most of the year gets pushed to its limit. If you need emergency heater repair in Rio Grande City, phone us with a quick description of the problem and of the people living in the house. We work on heat pumps, electric heat strips and furnaces, and we will be upfront about whether we can reach you the same day or early the next morning.

Is no heat an emergency in a South Texas freeze?

It can be, fast. Many Starr County homes have little insulation and were built to shed heat, not hold it. The February 2021 freeze from Winter Storm Uri made the point for many Valley families: with an outage and a dead heater on top of the cold, indoor temperatures fell within hours.

Treat it as urgent when:

  • The house is cold and an older adult, a baby or someone with a medical condition lives there
  • You smell gas, or a carbon monoxide alarm sounds (get everyone out first, then phone the gas company or 911)
  • There is a burning or electrical smell from the air handler or furnace
  • The breaker for the heat strips trips again after being reset
  • Indoor temperatures are dropping low enough to put water pipes at risk

Staying warm safely until help arrives

Poisoning and fires during freezes often come from improvised heat. Keep it safe:

  • Never heat the home with a gas oven, the stovetop, a grill or a generator. All of them give off carbon monoxide.
  • Run generators outside, far from doors, windows and vents.
  • Use electric space heaters carefully: clear space on every side, plugged directly into a wall outlet, turned off when you sleep or leave the room.
  • Close off unused rooms and gather in one, with blankets and layers.
  • Keep a working carbon monoxide alarm on each sleeping floor.

Heat pump frozen solid? Normal frost versus a real problem

Heat pumps pull heat from outdoor air, and in cold, damp weather their coils frost over. That is expected. Every so often the unit switches into a defrost cycle: the fan stops, the coil warms, and you may see steam rise. Then heating resumes.

It is a problem when the ice keeps building into a solid block, when the fan blades freeze, or when freezing rain glazes the top of the unit. Common causes include a failed defrost control or sensor, low refrigerant, a stuck reversing valve, or a unit sitting so low that melt water refreezes underneath it.

What you can do

If your thermostat has an emergency heat setting, switch to it. That shuts off the outdoor unit and runs the electric heat strips inside, which keeps the house warm while the heat pump waits for repair. Your electric bill will climb while it runs, so it is a bridge, not a fix.

Do not chip, pry or hammer at the ice. Coil fins and tubing are thin and puncture easily.

Emergency heat not working: heat strips, furnaces and controls

When the backup heat also fails, the usual suspects are:

  • Heat strip elements that burned open after a year of sitting unused
  • Sequencers or relays that switch the strips on in stages
  • Limit switches that trip from overheating, often because of a clogged filter
  • Separate breakers for the strips that tripped under heavy load
  • Gas furnace parts: a cracked igniter, a dirty flame sensor, a pressure switch or a blocked flue
  • Thermostat issues, including dead batteries or the wrong mode

A faint burning-dust smell on the first cold night is normal for a few minutes. A strong, lasting electrical or plastic smell is not; shut the system off and call.

How freeze calls are handled when the whole Valley is cold

A real freeze brings calls from Roma to La Grulla at the same moment, and roads and power can be unreliable. Here is how we handle it:

  1. Call during phone hours. The line is open six days, 8 AM until 7 PM, closed Sundays. On a Sunday, leave a message with your town, the heating type and who is home. You get a straight answer: either a same-day visit is realistic, or we book you into the first morning opening.
  2. Priority by risk. Households with older adults, babies or anyone medically fragile get the earliest openings.
  3. Safety before heat. On arrival we check for gas and carbon monoxide hazards and electrical damage first.
  4. Some heat running. Emergency heat, a reset strip circuit that tests safe, or a furnace restarted after the fault is found, even if a full repair needs a part.
  5. The failed part, explained. Nothing gets replaced until you know which part failed and what fixing it means.
  6. Repair and verify. The fix goes in, then we measure warm air at the registers and, on a heat pump, watch a defrost cycle clear the coil.

Why families call 956 Multi Service when the heat quits

Freezes are when a small local crew matters. We have worked from Rio Grande City since July 2024, so we know how few homes here were built to hold heat. Our Google profile carries 41 reviews, all 5.0, and reviewers keep pointing to on-time technicians who explain the work. We will not promise an arrival time during a statewide storm, but plenty of heater repairs wrap up on the day of the call when our calendar has room, and heat pumps still under a manufacturer warranty get a coverage check. You can settle up in cash or by card.

For non-urgent problems, our regular heating repair service handles the rest of the year. If you are weighing an upgrade after a freeze, heat pump service and installation explains newer cold-weather options. Summer breakdowns are covered on our main emergency AC repair page.

Cost factors for winter emergency heating repair

  • Timing: night, weekend and holiday calls cost more than weekday visits.
  • The failed part: a defrost board, heat strip element, igniter or sequencer each differ.
  • Supply during regional storms: when the whole state is cold, some parts are scarce.
  • Distance and road conditions on the day.
  • System type: heat pump, electric strip or gas furnace.
  • Temporary heat now, part later: getting emergency heat running today and returning with a defrost board can mean two trips.
  • Size of the strip kit: larger air handlers carry bigger, costlier elements and may need new breakers or wiring.
  • Hidden damage: a heat pump that ran iced for days may also have a refrigerant leak or a bent fan blade.
  • Sunday or holiday timing: we are closed Sundays, so a weekend failure may wait for Monday unless the risk is high.

Ask on the call what a first visit covers and what would add to it, so a cold night does not end with a surprise bill.

Carbon monoxide, gas and licensing rules for winter heat

A few outside rules matter more in a freeze than at any other time. The U.S. Consumer Product Safety Commission advises running portable generators outdoors at least 20 feet from windows, doors and vents, and keeping every side of a space heater three feet from beds, curtains and furniture. A gas smell means everyone goes outside before anyone phones the utility or 911. Fuel gas piping in Texas sits with the state plumbing board (TSBPE), while heating and cooling equipment work falls under TDLR's air conditioning and refrigeration licence; a Class B licence covers heating systems up to 1.5 million Btu per hour, far beyond any home. Ask for the licence number and check it online.

What do families ask about no-heat emergencies here?

What should I do if my heat pump ices over during a freeze?

Some frost is normal, and the unit clears it with a defrost cycle that can look like steam rising. If the outdoor unit stays encased in ice, set the thermostat to emergency heat if your system has heat strips, so the house keeps warming while the outdoor unit rests. Do not chip at the ice with tools, which can puncture the coil. Then call for service.

Is it safe to use the oven or a grill to heat the house?

No. Gas ovens, stovetops, charcoal or propane grills and generators all produce carbon monoxide, an odorless gas that can kill people in their sleep. Never use them to heat living space, and keep generators outside, well away from doors and windows. Use electric space heaters with clear space around them, plug them straight into the wall, and keep a working carbon monoxide alarm.

How fast can you respond during a winter storm?

During a regional freeze, calls come in from all over at once and roads or outages can slow everyone down, so we will not promise a time. Call and we will be honest about whether a same-day visit is realistic or whether the first opening the next morning is the better plan. Houses where older adults, babies or medically fragile people live are seen first.

Should I leave my heat pump on emergency heat until the technician arrives?

Yes, if the outdoor unit is iced over and the heat strips are working. Emergency heat keeps the house warm while the outdoor unit rests, though your electric bill climbs while it runs. If the strip breaker trips, leave it off and use safe backup heat instead. Switch back to normal heat once the repair is done, or the strips keep carrying the load.

Why does my heater smell like burning the first cold night?

A faint burning-dust smell for a few minutes is normal. Heat strips and furnace burners in Rio Grande City homes can sit unused for most of the year, and the dust that settled on them burns off. A smell that lasts, or one that smells like hot plastic or wiring, is different: switch the system off at the thermostat and call.
