Remember February 2021? When Fort Worth turned into an ice palace, and temperatures plummeted while our power grid decided to take a week-long vacation?
That storm taught us something important. Texas winters aren’t always mild, and when they turn nasty, they can shut down the entire city faster than you can say “frozen heat pump.”
Here’s the thing. Most Fort Worth homeowners aren’t prepared for extreme cold because it happens so rarely. But when your heating system fails at 2 AM with temperatures in the teens, you need answers right now, not next week.
That’s exactly why we created this guide. Whether you’re dealing with a frozen outdoor unit, a pilot light that won’t stay lit, or you just want to prepare before the next ice storm rolls through, we’ve got you covered with practical solutions that actually work.
R10 Heating & Cooling has served Fort Worth for over 30 years, and we’ve responded to every type of winter heating emergency imaginable. Our technicians are available 24/7 for emergency service at (817) 395-1200, because heating failures don’t wait for business hours.
This blog walks you through emergency heating tips for winter storms, helping you stay warm and safe when North Texas winter decides to get serious.
Why Fort Worth Homeowners Face Unique Heating Challenges During Winter Storms
Fort Worth sits in a unique weather zone that actually makes us more vulnerable during winter storms than you’d expect.
Our infrastructure wasn’t designed for sustained extreme cold. Unlike Minnesota or Michigan, where heating systems are built to handle weeks of sub-zero temperatures, our HVAC equipment is optimized for hot summers with occasional cold snaps. Heat pumps that work beautifully 95% of the year can struggle when temperatures drop below 25°F for extended periods.
Ice storms are our real enemy. While northern states get snow, Fort Worth gets ice, and ice is infinitely worse for power infrastructure. When your heating system requires electricity to run, and most do, grid failures mean instant heating failures.
Older HVAC systems are common throughout established Fort Worth neighborhoods. Many homes are running furnaces and heat pumps that are 15 to 20 years old. These systems might limp through normal winters just fine, but extreme cold exposes every weakness and accelerates component failures.
The typical Fort Worth ice storm lasts 2 to 4 days, with temperatures ranging from the teens to the low 30s. That’s long enough to cause serious damage to unprotected pipes and HVAC equipment, but short enough that many homeowners don’t take preparation seriously until it’s too late.
Understanding these unique vulnerabilities is your first step toward protecting your home and family.
Pre-Storm Heating System Checklist: What to Do 24-48 Hours Before
When the weather forecast starts showing snowflakes and ice warnings, it’s time to take action. Don’t panic, just act.
Test Your Heating System NOW
Turn your thermostat up a few degrees above your normal setting. You’re not trying to make your home uncomfortably warm. You’re testing whether your system can actually respond when you need it most.
Listen carefully while it runs. Rattling, grinding, squealing, or banging sounds mean something is wrong. Those unusual noises won’t magically fix themselves when temperatures drop to 15°F.
Check the airflow from your vents. Weak airflow often indicates a clogged filter or a bigger underlying problem. Put your hand near a register. You should feel strong, warm air pushing out.
Change your air filter if it’s been more than a month. A dirty filter is the number one cause of system failures we see during winter storms. This is a simple 5-minute fix that prevents expensive emergency calls.
Protect Your HVAC Equipment
Walk outside to your heat pump or air conditioning unit. Clear away leaves, debris, and anything within two feet of the unit. Airflow restrictions reduce efficiency and can cause system failures during extreme weather conditions.
Check any exposed pipes near your HVAC system. Even in Fort Worth, pipes can freeze when temperatures drop below 20°F for several hours. According to the American Red Cross, wrapping exposed pipes with insulation sleeves or heat tape now, before the storm hits, can prevent thousands in water damage.
Make sure your heating vents aren’t blocked by furniture, curtains, or storage boxes. Blocked vents create pressure imbalances that stress your system and waste energy heating spaces that don’t need it.
Emergency Supplies to Gather
Get an indoor-rated space heater if you don’t have one already. The keyword here is indoor-rated. Never use outdoor propane heaters or kerosene heaters inside your home. Look for electric space heaters with tip-over protection and automatic shut-off features for safety.
Stock up on extra blankets and warm clothing. If your heat fails during an ice storm, layering and insulation become your primary defense against the dangerous cold.
Keep flashlights and fresh batteries accessible. Don’t rely solely on your phone’s flashlight during a multi-day power outage. You’ll need that battery life for emergency calls and staying informed.
If you have a generator, make sure you have adequate fuel and know how to use it safely. Generators must run outside, at least 20 feet from any window, door, or vent. The CDC warns that generators produce deadly carbon monoxide gas that kills within minutes in enclosed spaces.
Know Your System Details
Find your water shutoff valve right now, before any emergency. When a pipe bursts, every second counts. Most homes have the main shutoff near the water meter or where the main line enters the house.
Know what type of heating system you have. Gas furnace? Electric heat pump? Dual fuel system? This information helps our technicians prepare the right parts and tools before they arrive at your home.
Save R10’s emergency number in your phone: (817) 395-1200. Also, save your homeowner’s insurance contact information. You might need it if pipes burst or equipment fails catastrophically.
Pro Tip: Schedule a pre-winter inspection with R10 before storm season hits. Our technicians check all the critical components that tend to fail during extreme cold. Preventive maintenance catches about 90% of potential failures before they happen. VIP members get two annual tune-ups that keep their systems running smoothly all year long.
What to Do When Your Heat Goes Out During a Fort Worth Ice Storm
Your heat just stopped working. It’s 1 AM, temperatures are dropping fast, and ice is coating everything outside.
Don’t panic. Let’s walk through this systematically.
Immediate Safety Checks (First 5 Minutes)
Check your thermostat batteries first. I know this sounds almost too simple, but dead batteries are responsible for countless “emergency” calls that aren’t actually emergencies. Replace them with fresh batteries and wait 30 seconds for the system to reset.
Walk to your electrical panel and check the circuit breaker for your HVAC system. Ice storms cause power surges that trip breakers frequently. If the breaker is tripped, flip it fully off, then back on.
If you smell gas, even a faint odor, evacuate immediately and call 911 from outside your home. Natural gas leaks are deadly serious. Don’t flip light switches, don’t use your phone inside the house, just get everyone out safely.
Verify your carbon monoxide detector is working properly. If you don’t have one, this is absolutely non-negotiable for next time. CO poisoning kills people during winter storms when they resort to improper heating methods.
Quick Troubleshooting Steps
Make absolutely certain your thermostat is set to HEAT mode, not cool or off. Touch the screen or press buttons to wake it up. Some programmable thermostats go into power-saving mode and need to be reactivated.
Pull out your air filter and hold it up to a light. If you can’t see light passing through it, it’s too clogged. Replace it immediately. A severely clogged filter can trigger safety shutdowns in modern furnaces.
For gas furnaces, locate the pilot light viewing window. If you don’t see a small blue flame, the pilot is out. Some modern furnaces use electronic ignition instead, so check your owner’s manual. Never attempt to relight a pilot if you smell gas anywhere.
Double-check that circuit breaker again. Sometimes breakers appear to be on but are actually partially tripped. Push it firmly to the off position, then back to on.
When to Call R10 Emergency Service
Call R10 immediately at (817) 395-1200 if your heating system is completely dead after trying the basic troubleshooting steps above. Our emergency technicians are available 24/7, and we understand that heating failures during ice storms are genuine emergencies, not inconveniences.
EMERGENCY HEATING SERVICE: (817) 395-1200
Available 24 hours a day, 7 days a week, including holidays and ice storms
Call us right away if you notice strange smells like burning plastic, rotten eggs (indicating gas), or electrical burning. These indicate serious problems that require immediate professional attention.
Loud banging, screeching, or grinding noises mean internal components are failing. Running the system in this condition causes additional damage. Shut it down and call for service.
If you see ice accumulation on your outdoor heat pump unit that doesn’t go away after 30 minutes, something is wrong with the defrost cycle. Normal defrost cycles should clear ice regularly.
Suspect frozen pipes if you have no water flow, hear running water behind walls, or see frost forming on exposed pipes. This situation deteriorates rapidly and can cause thousands of dollars in water damage.
Safe Alternative Heating Methods
Space heaters are safe if you use them correctly. Keep them at least three feet away from anything flammable, including furniture, curtains, papers, and blankets. Never run them unattended or while you’re sleeping. Plug them directly into wall outlets, never into extension cords or power strips.
Create a “warm room” strategy for your family. Choose one room, preferably an interior room with a door, and focus your heating efforts there. Close doors to other rooms. Hang blankets over doorways to trap heat. The smaller the space, the easier it is to keep warm with limited resources.
Close your curtains and blinds at night for insulation, but open them during sunny days on south-facing windows to capture passive solar heat.
Never, ever use these for indoor heating:
- Your kitchen oven or stove
- Outdoor propane or camping heaters
- Charcoal or gas grills
- Generators (must stay outside)
- Cars running in attached garages
These methods produce carbon monoxide that kills silently and quickly. Every winter storm, people die from making these mistakes.
Protect Your Home While Waiting for Service
Let your faucets drip when temperatures drop below 25°F. A slow drip, about five drips per minute, keeps water moving through pipes and prevents freezing. Both hot and cold water should drip.
Open cabinet doors under sinks to let warm air reach the pipes. This is especially important for bathrooms and kitchens located on exterior walls.
Keep at least one faucet running slightly if temperatures will stay in the teens for more than 24 hours. Yes, this wastes some water, but it’s far cheaper than repairing burst pipes.
Try to maintain at least 55°F inside your home, even if you have to retreat to one warm room. Below this temperature, pipe freeze risk increases dramatically.
Top 5 Heating Failures We See During Fort Worth Winter Storms
After 30 years of emergency calls, we’ve seen the same problems occur again and again. Here’s what actually fails when temperatures plummet.
- Frozen Heat Pump
Heat pumps work by extracting heat from outdoor air, which sounds impossible when it’s 15°F outside, but the technology actually works remarkably well. The problem is that ice builds up on the outdoor coil during normal operation.
Your heat pump should defrost automatically every 30 to 90 minutes. It temporarily switches into cooling mode to melt the ice, then returns to heating. You might see steam rising from the unit during defrost cycles, and that’s completely normal.
Signs your heat pump is frozen and not defrosting properly: solid ice coating the entire unit, no warm air coming from your vents, outdoor fan not spinning, frost remaining for multiple hours. This happens when defrost controls fail or when temperatures stay extremely low for days without relief.
R10’s fix: We check the defrost control board, temperature sensors, and reversing valve. Often it’s a failed defrost thermostat or control board. Sometimes the auxiliary heat strips have failed, so the system lacks the heat needed to melt accumulated ice.
- Pilot Light Failure
Modern gas furnaces often use electronic ignition instead of standing pilot lights, but many Fort Worth homes still have older furnaces with conventional pilots that burn continuously.
Wind from winter storms can blow out pilot lights. Thermocouple failures prevent successful relighting. Dirty pilot assemblies cause weak flames that extinguish easily under stress.
When to DIY: If your furnace is older, your owner’s manual has clear relighting instructions, and you smell absolutely no gas, you can attempt to relight it yourself following the manufacturer’s exact instructions.
When to call a professional: If the pilot won’t stay lit after 2 to 3 attempts, you smell any gas odor, or you’re uncomfortable working near gas appliances. Don’t keep trying repeatedly. You’re wasting valuable time and potentially creating a dangerous gas buildup.
- Clogged Air Filter Shutdown
This is the most preventable failure we encounter. Modern furnaces have safety limit switches that shut down the entire system if airflow becomes too restricted. The system is protecting itself from dangerous overheating.
A severely clogged filter restricts airflow so dramatically that the furnace overheats within minutes of starting. The limit switch trips, and everything stops working.
The 5-minute fix: Turn off your system completely. Replace the filter with a new one. Keep spare filters on hand always. Wait 30 minutes for the limit switch to cool and reset. Turn the system back on. Most times, it starts right up and runs perfectly.
If you have a spare filter available, this is one emergency repair you can absolutely do yourself. If you don’t have a replacement filter, you’re stuck calling for service. This is exactly why we tell everyone to keep backup filters stored in their garage or utility closet.
- Electrical Issues from Ice and Power Surges
Ice storms create havoc with electrical systems. Power surges when electricity is restored after outages can damage sensitive electronics in modern HVAC systems.
Circuit breakers trip. Fuses blow. Control boards get fried. Transformers fail. Sometimes your furnace is perfectly fine, but your thermostat got zapped by a surge.
R10’s fix: We test all electrical components systematically. Control boards, transformers, capacitors, and contactors—every electrical component gets checked with proper testing equipment. Sometimes it’s a simple breaker reset. Sometimes we’re replacing a control board that costs several hundred dollars.
Protection tip: Consider having a whole-home surge protector installed at your electrical panel. It won’t prevent every problem, but it helps protect your expensive HVAC equipment from damaging voltage spikes.
- Frozen Condensate Line
High-efficiency furnaces produce condensation that drains through a small PVC pipe. When this pipe freezes solid, water backs up and triggers a safety switch that shuts down the furnace immediately.
You’ll see: water pooling around the base of your furnace, gurgling sounds from the condensate drain, system shutting down repeatedly after running for just a few minutes.
This happens because the condensate line runs through an unheated space like your attic, crawlspace, or outside your home, and freezes solid when temperatures drop below freezing for extended periods.
R10’s fix: We clear the frozen line, often using warm water or heat tape carefully applied. Then we properly insulate the line to prevent recurrence. Sometimes we reroute the line entirely to avoid unheated spaces where freezing is likely.
Staying Warm When Both Heat AND Power Are Out
This is the worst-case scenario, but February 2021 proved it absolutely can happen in Fort Worth.
Generator safety is critically important and non-negotiable. Generators produce carbon monoxide that can kill within minutes in enclosed spaces. They must run outside, at least 20 feet from any window, door, or vent. Point the exhaust away from your house.
Never run a generator in your garage, even with the door open. Never run it in your basement. Never run it on your covered porch. People die every single year from making these mistakes. Follow manufacturer safety guidelines exactly as written.
Body heat preservation becomes crucial without any power source. Layer your clothing. Multiple thin layers trap air and insulate better than one thick layer. Cover your head because you lose significant heat through your scalp. Keep your hands and feet covered and dry.
Create a warm room strategy for your household. Choose the smallest room with the fewest windows. Close all doors. Hang blankets over windows and doorways. Gather everyone in this space. Body heat from multiple people can keep a small room surprisingly warm even without any heat source.
When to evacuate to warming centers: If indoor temperatures drop below 50°F and you have elderly family members, infants, or people with health conditions in your household. If you have absolutely no heat source for more than 24 hours. If pipes are freezing and you can’t prevent it.
Fort Worth opens warming centers during severe winter weather. Check these resources for current locations:
- City of Fort Worth Emergency Management
- Tarrant County Resources
- American Red Cross North Texas
- Call 211 for current warming center locations
Pipe protection without electricity is challenging but possible. Let faucets drip even without power because gravity still works. Open cabinet doors. If you still have water pressure, fill bathtubs before pipes freeze completely. The water provides drinking water and toilet flushing capability.
Safety Warning: Things You Must NEVER Do During a Power Outage
- Run generators indoors or in attached garages
- Use gas stoves or ovens for heat
- Burn charcoal indoors (produces deadly CO)
- Use outdoor propane heaters inside
- Run your car in an attached garage for warmth
- Bring outdoor grills inside your home
- Leave candles burning unattended
These mistakes kill people every year during winter storms. No matter how desperately cold you feel, these are never safe options.
Post-Storm HVAC Inspection: What to Check After the Storm
Your heat came back on. Power is restored. The ice melted. Everything seems fine now.
Don’t automatically assume it is fine.
Just because your heating system is currently running doesn’t mean it escaped damage during the storm. Freeze-thaw cycles can crack heat exchangers, damage refrigerant lines, or weaken components that will fail next month when you least expect it.
Walk around your home and check for water damage near your HVAC equipment. Look for water stains on ceilings under your attic furnace. Check for puddles around your indoor unit. Inspect insulation for wetness. These indicate leaks that occurred during the storm.
Inspect all visible pipes for cracks or splits. Even tiny hairline cracks can cause major water damage over time as they gradually worsen. Look for frost or ice that hasn’t melted yet. This might indicate hidden frozen sections still at risk.
Listen carefully for new noises from your heating system. Rattling, hissing, or banging sounds that weren’t present before the storm indicate something changed. Maybe a component shifted position. Maybe something cracked under stress. Get it checked before it fails completely.
Schedule an inspection even if everything seems okay on the surface. R10’s technicians know exactly what storm damage looks like and where to find it. We check heat exchangers for cracks, test refrigerant levels, inspect electrical connections, and verify all safety controls work properly.
Hidden freeze-thaw damage is particularly insidious. A heat exchanger crack might be microscopic after the storm but grow larger with each heating cycle. Refrigerant leaks might be slow enough that you won’t notice reduced heating capacity for weeks. Electrical damage might cause intermittent failures that are extremely difficult to diagnose later.
Document everything thoroughly for insurance purposes. Take photos of any visible damage. Save all receipts for emergency repairs. Keep detailed notes about what failed and when it failed. If you needed emergency service during the storm, those repair bills might be covered by your homeowner’s insurance policy.

How R10’s VIP Membership Prevents Winter Heating Emergencies
Here’s something we’ve learned after responding to thousands of emergency calls over three decades: most winter heating failures are actually preventable.
Fall tune-ups catch approximately 90% of the problems that cause failures during winter storms. Dirty burners, weak ignitors, failing capacitors, refrigerant leaks—our technicians spot these developing issues during routine maintenance before they fail at the worst possible time.
During an R10 VIP inspection, our technicians check every single critical component in your system. We test your ignition system under actual load conditions. We measure airflow and static pressure throughout your ductwork. We inspect heat exchangers carefully for any cracks. We check refrigerant levels and pressures. We test all safety controls to verify they’ll protect you. We verify that electrical connections are tight and secure. We clean burners and flame sensors that get dirty over time.
The cost comparison is honestly stark. An annual VIP membership costs just $99 per year. Emergency repairs during ice storms? Expect $300 to $800 for typical failures, often significantly more for major component replacements. A single prevented emergency call literally pays for years of membership.
VIP membership benefits include:
- Two comprehensive tune-ups per year (spring and fall)
- Priority scheduling—VIP members always get served first
- 15% discount on all repairs and replacements
- No overtime charges ever for emergency service

Fort Worth Winter Heating Emergency FAQs
How long can I safely run my heat during an ice storm?
Run your heating system continuously if needed. That’s exactly what it’s designed to do. Modern furnaces and heat pumps can operate 24/7 without any damage to the equipment. The risk isn’t from running it too much, but from frozen outdoor components or power fluctuations during the storm. Keep your thermostat at a comfortable temperature rather than cycling it up and down repeatedly.
What thermostat temperature should I maintain during winter storms?
Aim for 68 to 70°F during waking hours and at least 65°F while everyone is sleeping. Never let interior temperatures drop below 55°F because that’s when pipe freeze risk increases significantly. If you’re trying to conserve energy during a power outage with limited generator fuel, 60 to 62°F is the minimum safe temperature to maintain.
Are space heaters safe to use during power outages?
Electric space heaters obviously won’t work without electrical power available. If you have generator power, they’re safe when used correctly: plugged directly into wall outlets (never extension cords), positioned at least three feet from any flammable materials, never left unattended, and equipped with tip-over shutoff safety features. Never use propane or kerosene heaters indoors because they produce deadly carbon monoxide.
How do I know if my frozen heat pump is in normal defrost mode or actually broken?
Normal defrost cycles last 2 to 15 minutes and occur every 30 to 90 minutes when outdoor temperatures are cold. You’ll see steam rising, hear the outdoor fan stop temporarily, and feel cool air from your vents briefly during the defrost cycle. If ice remains on your unit for multiple hours, ice covers the entire coil completely, or you never observe defrost cycles occurring at all, something is definitely wrong. Call for professional service.
Can R10 actually reach me during an ice storm?
Yes, we can reach you. We have 4-wheel drive service vehicles, and our technicians are experienced at navigating icy Fort Worth roads safely. We prioritize service calls based on severity—total system failures and safety issues get immediate priority. During February 2021, our team worked around the clock to help Fort Worth homeowners stay warm and safe. We can’t promise instant arrival during the absolute worst weather conditions, but we will reach you as quickly and safely as possible.
What’s the average cost for emergency heating repairs?
Emergency service calls start at $300 to $400 for basic repairs like replacing ignitors, cleaning flame sensors, or resetting tripped systems. More complex repairs involving control boards, heat exchangers, or compressors typically run $500 to $1500, depending on the specific component. Complete system replacements during emergencies cost $3000 to $8000, depending on equipment type and size. VIP members save 15% on all repairs and never pay overtime charges for emergency service.
How quickly do frozen pipes cause damage once they actually burst?
Once a frozen pipe actually bursts open, water damage begins immediately and accumulates rapidly. A 1/8-inch crack can spray hundreds of gallons of water per day throughout your home. The real danger often comes when ice melts rather than during the freeze itself. Pipes frequently burst during the thaw, not during the freeze. This is exactly why you should carefully inspect all plumbing after temperatures rise back above freezing.
Should I turn off my HVAC system if I see ice on the outdoor unit?
It depends on the amount and persistence of ice. A thin coating of frost is completely normal and will defrost automatically during regular defrost cycles. Heavy ice accumulation that doesn’t clear after an hour means something is wrong with the defrost cycle. If you see solid ice coating and the system is still running but not heating well, turn it off and switch to emergency heat if your system is equipped with it. Then call R10 for service. Running a frozen heat pump can damage the expensive compressor.
What if my heating emergency happens on Christmas Day or New Year’s?
R10 provides 24/7/365 emergency service, and yes, that absolutely includes holidays. Heating failures don’t respect the calendar or wait for convenient times. Our emergency technicians work every single holiday because we know frozen pipes and failed furnaces create genuine emergencies for families. Call (817) 395-1200 anytime, day or night, and we’ll get someone to you as quickly as possible.
Can I prevent winter heating emergencies completely?
Not 100% completely, but you can reduce your risk by approximately 90% with proper preventive maintenance. Annual tune-ups catch failing components before they actually fail during a storm. Keeping filters changed regularly prevents airflow problems. Clearing snow and ice from outdoor units helps heat pumps operate efficiently.
Stay Warm, Stay Safe, Stay Prepared
Winter storms will hit Fort Worth again. That’s not pessimism or fear-mongering. That’s simply North Texas reality.
