What Customers Say in Waterloo

“Called at 11 p.m. with no AC and a newborn in the house. A real person answered and a tech was here before 1 a.m. Cannot say enough.”

Jonathan K., Waterloo

“Furnace was short cycling every five minutes. Turned out to be a flame sensor and a dirty filter. Honest fix, honest price.”

Carla D., Waterloo

“Duct sealing made a bigger difference than I expected. Upstairs finally cools down and the system is not running all day.”

Terrence L., Waterloo

Furnace Repair in Waterloo: Questions We Hear

Why does my furnace keep shutting off?

Short cycling is usually a dirty filter, a failing flame sensor, an oversized furnace or a limit switch tripping from restricted airflow.

Is a cracked heat exchanger dangerous?

Yes. It can leak carbon monoxide into the home. We inspect it on every furnace repair in Waterloo.

How long do furnaces last?

Gas furnaces typically run 15 to 20 years with annual service. Electric furnaces can go longer.
