Winter Furnace Issues to Watch For 

Even well-maintained systems face unique challenges in winter. Here’s how cold weather can stress your furnace and cause issues specific to the season: 

  • Frozen Intake or Exhaust Pipes: Frigid temperatures can cause condensation in exhaust lines to freeze, leading to shutdowns or dangerous airflow blockages in high-efficiency furnaces.
  • Overworked Systems During Cold Snaps: Extended cold periods can force your furnace to run non-stop, increasing wear on parts like blower motors and heat exchangers.
  • Dry Indoor Air: Winter air naturally holds less moisture, and your furnace can make things worse. This can lead to dry skin, sinus irritation, and damage to wood furniture or flooring.
  • Carbon Monoxide Risks from Blocked Vents: Snow and ice buildup outside can block furnace vents, causing dangerous gases like carbon monoxide to back up into your home.
  • Delayed Ignition Due to Cold Components: Cold weather can cause gas valves or ignition systems to delay starting, especially if your furnace hasn’t been serviced recently or is nearing the end of its life.

Why Should You Schedule Our Furnace Maintenance Service? 

Should you need furnace repair or a full furnace replacement in Lancaster, PA, or the surrounding area, we’re here for you. However, we do recommend proactive furnace maintenance as your first line of defense during winter. 

When you get your furnace inspected before the cold of winter arrives, you’re able to find issues before they become unexpected malfunctions. 

Annual furnace maintenance can help prevent emergency situations during the dead of winter, and they can even help postpone the eventual need for a full furnace replacement. It also helps keep your family safe from CO leaks and your system working efficiently throughout the cold season. 

Do your furnace and home a favor by getting regular furnace maintenance service. 

Winter Furnace FAQs

What should I do if my furnace stops working in freezing temps?

First, check the thermostat, circuit breaker, and furnace filter. If the problem persists, call us for emergency services. Fast, reliable help is on the way! 

How often should I schedule furnace maintenance? 

At least once per year—ideally in the fall—before winter demand hits. Inspections ensure safe and efficient performance when you need it most. 

Why does my furnace blow cold air sometimes? 

This problem could mean a dirty filter, pilot light issue, or overheating. A winter tune-up can catch these problems early. 

Is it normal for my furnace to smell when it first turns on? 

A brief dusty smell is common if the system hasn’t run in a while. However, a burning or gas odor is a sign to call for service immediately. 

Should I repair or replace my old furnace before winter? 

If your unit is over 15 years old or frequently needs repairs, replacement may be the safer and more cost-effective option for the season.
