No Heat? What to Do When Your Furnace Stops Working in Freezing Temperatures

Emergency Furnace Repair Lexington KY

Introduction

There is nothing more stressful for a homeowner than waking up to a cold house during a freezing Kentucky winter. When outdoor temperatures drop into the teens or single digits, losing heat isn’t just uncomfortable—it can quickly become a safety issue. That’s why searches for Emergency Furnace Repair Lexington KY spike every time a major cold snap hits Central Kentucky.

The worst part? Furnace breakdowns almost always happen at the worst possible time—late at night, on weekends, or during holidays when your system is under maximum demand. Pipes can freeze, indoor temperatures can drop fast, and families are left scrambling to figure out what to do next.

This guide walks you through exactly what to do when your furnace stops working in freezing temperatures, what you can safely check on your own, what you should never attempt, and when it’s time to call a professional. We’ll also explain how homeowners can prevent emergency breakdowns in the first place with proactive maintenance from Lexington Electrical & HVAC and our Cool & Cozy Club.

Why Furnaces Fail During Freezing Temperatures

When temperatures plunge, furnaces run longer and harder than at any other time of year. That extended runtime exposes weak components that may have gone unnoticed earlier in the season.

Common reasons furnaces fail during freezing weather include:

Dirty or failing flame sensors
Restricted airflow from clogged filters
Worn igniters
Overheating due to poor airflow
Electrical issues caused by cold contraction
Failing blower motors or capacitors
Safety switches tripping repeatedly

According to http://energy.gov , heating systems that are not properly maintained are far more likely to fail during extreme cold, especially when they are suddenly required to operate continuously.

Step 1: Stay Calm and Check These Things First

Before assuming the worst, there are a few safe checks homeowners can perform. These steps won’t fix major problems, but they can help rule out simple issues.

Check the Thermostat

Make sure it’s set to Heat, not Cool
Set the temperature at least 5 degrees above room temperature
Replace thermostat batteries if applicable

Check the Furnace Power

Confirm the furnace switch is turned on
Check the circuit breaker for a tripped breaker
Reset only once—do not repeatedly flip breakers

Check the Air Filter

A severely clogged filter can cause the furnace to shut down
Replace the filter if it’s dirty
Never run the system without a filter

Check the Gas Supply (Gas Furnaces)

Ensure the gas shutoff valve is open
If you smell gas, leave the home immediately and call the gas company

If the furnace still won’t run after these checks, it’s time to stop troubleshooting and call for Emergency Furnace Repair Lexington KY .

What NOT to Do When You Have No Heat

In freezing temperatures, homeowners often panic—and that’s when mistakes happen. Avoid these actions at all costs:

❌ Repeatedly resetting breakers or the furnace
❌ Attempting DIY electrical or gas repairs
❌ Running ovens or grills for heat
❌ Using unvented space heaters improperly
❌ Ignoring strange smells or noises

These actions can damage your system further or create serious safety hazards, including fire and carbon monoxide exposure.

When No Heat Becomes an Emergency

Not every heating issue is an emergency—but in freezing weather, many are.

You should call for Emergency Furnace Repair Lexington KY immediately if:

Indoor temperatures are dropping rapidly
Children, elderly residents, or pets are in the home
Outdoor temperatures are below freezing
Pipes are at risk of freezing
The furnace makes loud banging or grinding noises
You smell burning or gas odors

The longer you wait, the more damage can occur—not just to your HVAC system, but to your home itself.

Common Emergency Furnace Repairs in Lexington Homes

During freezing weather, we most commonly repair:

Flame sensors
Igniters
Capacitors
Blower motors
Limit switches
Pressure switches
Control boards
Thermostat failures

Many of these failures could have been prevented with seasonal maintenance.

Why Emergency Repairs Cost More Than Maintenance

Emergency furnace repair is almost always more expensive than preventative service because:

Failures occur during peak demand
Parts may be urgently required
Systems often sustain additional damage
After-hours labor may be needed

Routine maintenance helps identify failing components before they cause a total shutdown—saving homeowners money, stress, and discomfort.

How to Protect Your Home While Waiting for Service

If you’re waiting on emergency service, take steps to protect your home:

Keep cabinet doors open to allow warm air near plumbing
Let faucets drip slightly to prevent frozen pipes
Close unused rooms to conserve heat
Use safe, approved space heaters only if necessary
Stay in the warmest room of the house

Never attempt unsafe heating methods.
