How to Handle a Broken Heater in the Middle of Winter

December 11, 2025

When temperatures plunge and your home suddenly feels more like a walk-in freezer, a broken heater can be more than an inconvenience, it can be an emergency. The middle of winter is the worst time to be without heat but knowing what steps to take can help protect your home, your family, and your comfort. At Custom Cooling & Heating, we help homeowners restore warmth quickly and safely. Here’s what to do if your heater stops working when you need it most. 



1. Check the Basics First 

Before assuming the worst, start with a few simple troubleshooting steps. Many heating failures are caused by basic issues that can be resolved without a service call. 


  • Check your thermostat: Make sure it’s set to “Heat” and that the temperature is set higher than your home’s current indoor temp. If it’s a battery-powered thermostat, swap in fresh batteries. 
  • Inspect your circuit breaker: A tripped breaker can shut your furnace down completely. Reset it if necessary. 
  • Ensure your furnace switch is ON: Furnaces often have a standard light-switch-style power switch on or near the unit. Make sure it wasn’t accidentally turned off. 
  • Look at your air filter: A severely clogged filter can restrict airflow and cause your system to shut down for safety. If the filter looks dusty or blocked, replace it. 


If these quick checks don’t restore heat, the issue may be deeper inside the system and require professional attention. 



2. Avoid Overworking Your System 

When heat stops flowing, it’s natural to keep adjusting the thermostat, hoping the furnace will kick back on. Try to avoid repeatedly turning the system on and off, as this can make the situation worse or cause damage. 


Instead, turn the system off if you smell burning, hear unusual noises, or see signs of overheating. These can signal electrical issues or mechanical failures that need a technician. 



3. Use Safe Temporary Heating Solutions 

While waiting for repairs, you'll need to keep your home comfortable, but safety should always come first. Avoid using your oven or grill to heat your home, as these methods are extremely dangerous. 


Safer alternatives include: 


  • Electric space heaters: Keep them on a stable surface, at least three feet from flammable items. 
  • Fireplaces: Ensure the flue is open for proper ventilation. 
  • Layered clothing and blankets: A simple and safe short-term solution. 


If indoor temperatures drop too low, consider staying with a friend, family member, or in a hotel to avoid the risk of frozen pipes or health issues. 



4. Prevent Your Pipes from Freezing 

A broken heater doesn’t just affect comfort, but it can also put your plumbing at risk. Frozen pipes can burst and cause significant water damage. To help prevent freezing: 


  • Keep cabinet doors open to allow warm air around plumbing. 
  • Let faucets drip slowly to keep water moving. 
  • If your home has multiple stories, keep doors open between rooms to allow even air circulation. 


If temperatures in your home drop below 55°F, your pipes may be at risk, so monitor them closely until the heat is restored. 



5. Call a Professional HVAC Technician 

If basic troubleshooting doesn’t resolve the issue, it’s time to call a certified expert. Heating systems have complex electrical, mechanical, and safety components, so attempting repairs without training can be dangerous. 


At Custom Cooling & Heating, our technicians diagnose heater breakdowns quickly and offer reliable solutions to get your home warm again. Whether it’s a faulty ignitor, blower motor issue, dirty flame sensor, or aging furnace components, we’ll pinpoint the problem and recommend the most cost-effective fix. 



6. Consider the Age of Your Heater 

If your heater is over 12–15 years old, repeated breakdowns may be a sign that it’s time for replacement. Older units lose efficiency, struggle to maintain consistent temperatures, and can increase your energy bills. 


A new high-efficiency heating system can: 


  • Reduce monthly utility costs 
  • Improve indoor air quality 
  • Deliver more consistent comfort 
  • Provide safer, more reliable performance 


Our team can help you compare repair vs. replacement options, so you can make the best choice for your budget and home. 



7. Prevent Future Breakdowns with Regular Maintenance

Once your heat is restored, the best way to avoid another winter surprise is to schedule annual furnace maintenance. Preventive service keeps your system running smoothly and can catch small issues before they turn into emergencies. 


Routine maintenance from Custom Cooling & Heating includes: 


  • Full system inspection 
  • Cleaning and lubrication 
  • Filter replacement 
  • Safety checks 
  • Efficiency testing 


Not only does this reduce the risk of winter breakdowns, but it also extends the life of your equipment.

A broken heater in the middle of winter can be stressful, but you don’t have to handle it alone. The experts at Custom Cooling & Heating are here to restore your comfort quickly and safely. Whether you need emergency repairs, routine maintenance, or a new system installation, our team is ready to help.

How Nebraska Weather Impacts Your HVAC System Year-Round

July 2, 2026
Nebraska weather can be hard on any heating and cooling system. In Lincoln, homeowners deal with freezing winter temperatures, windy spring weather, hot summer days, and seasonal temperature swings that can put extra strain on HVAC equipment. For anyone looking for reliable HVAC in Lincoln, NE, understanding how weather affects your system can help you prevent breakdowns, improve efficiency, and keep your home comfortable all year.  At Custom Cooling and Heating , we know how quickly Nebraska conditions can affect furnaces, air conditioners, filters, and airflow. Each season creates different challenges, and staying ahead of them can help you avoid costly repairs. Winter Can Push Your Furnace to Its Limit Cold Nebraska winters often mean your furnace runs for long stretches without much of a break. When temperatures stay low, your heating system must work harder to maintain indoor comfort. That added demand can expose problems like dirty filters, worn components, ignition issues, or poor airflow. Homeowners may notice uneven heating, cold spots in certain rooms, or higher energy bills during the winter. If your furnace is older or has not been maintained, winter is often when those hidden problems show up. Scheduling heating service before peak cold weather can help your HVAC in Lincoln, NE run more efficiently and reduce the chance of an unexpected breakdown. Spring Weather Can Affect Air Quality and Airflow Spring in Nebraska often brings wind, dust, and pollen. Those conditions can affect both indoor air quality and HVAC performance. A clogged air filter or dirty ductwork can make it harder for your system to circulate clean air, especially during seasonal transitions when temperatures change quickly. If your home feels dustier than usual or allergy symptoms seem worse indoors, your HVAC system may be contributing to the problem. Replacing filters and checking airflow in the spring can help improve comfort before summer heat arrives. Summer Heat Makes Your AC Work Harder Hot summer weather in Lincoln puts major demand on air conditioning systems . During periods of high heat, your AC may run longer and more often to keep up. If your system already has issues such as dirty coils, low refrigerant, or weak airflow, summer is when they are most likely to affect performance. Some of the most common warning signs include rising utility bills, longer cooling cycles, uneven room temperatures, or an AC unit that struggles to keep the house comfortable. Preventive maintenance before summer can help identify small issues early and keep your system ready for the hottest part of the year. Fall Is the Best Time to Prepare for Heating Season Fall is one of the best times to schedule HVAC maintenance in Lincoln. After months of summer cooling and before winter heating demand begins, this is a smart time to inspect your system, replace filters, and make sure everything is working properly. A fall tune-up can help catch worn parts, thermostat problems, or airflow issues before colder temperatures arrive. It can also improve efficiency and help your furnace operate more reliably when you need it most. Nebraska Weather Affects HVAC Efficiency Year-Round Seasonal extremes are not the only issue. Nebraska’s constant shifts in temperature, humidity, and airflow can gradually wear down HVAC components over time. Motors, electrical parts, filters, and duct systems all work harder when your system is constantly adjusting to changing weather. According to the U.S. Department of Energy , routine HVAC maintenance, including changing air filters and scheduling regular inspections, helps systems operate more efficiently, improves airflow, and can extend the life of your equipment. Staying on top of maintenance is one of the best ways to prepare your heating and cooling system for Nebraska's changing seasons. That is why routine maintenance matters throughout the year. A well-maintained system is more likely to handle seasonal stress, perform efficiently, and avoid unnecessary wear.

HVAC Repair vs. Replacement in Lincoln, NE: How to Know When It's Time for a New System

June 11, 2026
When your HVAC system starts having problems, one of the most important decisions you'll face is whether to repair your current unit or invest in a new one. For homeowners in Lincoln, NE, Nebraska's hot summers and cold winters can put significant strain on heating and cooling equipment. At Custom Cooling & Heating , we help Lincoln-area homeowners evaluate their options and make the best decision for their comfort and budget. How Long Do HVAC Systems Last? Lincoln's seasonal temperature swings can take a toll on HVAC systems over time. Between summer air conditioning demands and winter heating needs, homeowners in Lincoln, NE often experience more wear and tear than systems in milder climates. Regular maintenance plays a significant role in extending the life of your HVAC system and helping it operate more efficiently over time. Most systems last around 10 to 15 years, though some can last even longer with proper care. As your system ages, wear and tear, climate conditions, and usage patterns can begin to affect its performance. If your HVAC system is approaching this age range, you may start to notice issues like: Uneven cooling or heating Strange noises or odors Higher energy bills Frequent cycling on and off Excess dust or humidity If you’re noticing any of these, it’s time to weigh your options. When to Choose HVAC Repair If you're looking for HVAC repair in Lincoln, NE, repairing your system is often the most cost-effective option when the unit is relatively new and the issue is isolated. Consider repair if: Your system is under 10 years old and has been regularly maintained. The issue is isolated, like a broken thermostat, clogged filter, or worn capacitor. The repair cost is less than half the price of a new unit. Custom Cooling & Heating offers fast, honest repairs. Our certified technicians will diagnose the problem and provide clear options, so you only pay for what you need. When to Replace Your HVAC System Replacement is often the smarter choice if: Your system is over 10-15 years old. You need frequent repairs because costs add up quickly. Your energy bills are rising due to declining efficiency. You want newer features like smart controls or better air quality. According to the Energy Star, upgrading to an Energy Star-rated HVAC system can save you up to 20% on energy costs. At Custom Cooling & Heating, we offer free estimates on new installations and will help you select the right system for your home. Repair vs Replacement: Comparing Costs It’s tempting to pick the cheapest option, but ongoing repairs and high energy bills can make an old system more expensive in the long run. Here’s a quick tip: Multiply the cost of the repair by the age of your system. If the result is more than $5,000, replacement may be your best choice. Other factors to consider: New systems are more efficient and save money every month. New units come with warranties, protecting you from future costs. Older systems are more likely to break down at inconvenient times. Why Choose Custom Cooling & Heating?
