Signs Your Furnace Needs Repair

Northwest Indiana winters are hard on heating systems. If your furnace is showing any of these signs, don't wait — small problems turn expensive fast when the temperature drops.

Not Heating Evenly
Some rooms are warm while others stay cold. Usually a duct, blower, or heat exchanger issue.
Short Cycling
Furnace kicks on and off repeatedly without completing a full heating cycle. Wastes energy and stresses the system.
Unusual Noises
Banging, rattling, squealing, or booming when the furnace runs. Often a loose component or ignition problem.
Pilot Light Issues
Yellow or flickering pilot light instead of a steady blue flame. Can indicate a carbon monoxide concern.
Heating Bills Spiking
A sudden increase in gas or electric bills usually means the furnace is working harder than it should.
Furnace Won't Start
No heat at all. Could be the thermostat, igniter, control board, or gas supply — a quick diagnosis tells you exactly what it is.

Common Furnace Problems We Fix

Most furnace failures in Northwest Indiana come down to a handful of issues. Here's what we see most often:

Igniter or Thermocouple Failure
One of the most common furnace repairs. The igniter wears out over time and can usually be replaced quickly.
Cracked Heat Exchanger
A cracked heat exchanger is a safety issue — carbon monoxide can enter your living space. This requires prompt attention.
Blower Motor Issues
The blower pushes heated air through your ducts. When it fails or runs continuously, airflow and efficiency both suffer.
Dirty or Failing Flame Sensor
Causes the furnace to shut off after a few seconds. Often a simple cleaning fixes it.
Control Board Problems
The brain of the furnace. When it fails, symptoms can look like almost anything — which is why proper diagnosis matters.
Clogged Filter or Restricted Airflow
A dirty filter causes the furnace to overheat and cycle off. It's the first thing we check — sometimes the only fix needed.

What Our Customers Say

Real reviews from Highland and NW Indiana homeowners.

★★★★★

"Our furnace went out, and after getting a sky-high repair quote from another company, we decided to call Collins for a second opinion. Mark came out, quickly diagnosed the real problem, and fixed it for a fraction of the first quote. We felt so informed and taken care of."

"My heat went out and from the reviews and being a local business I called Collins. Mark was able to come that day. He got the part and was here first thing the next day to install. He was informative and nice. I would definitely use Collins again."

"I called out a company for a furnace cleaning and from the moment they opened the door it was gloom and doom. I called Collins for a second opinion. Mark thoroughly inspected the furnace and assured me it was in fine working order. He saved me thousands of dollars."
