At DeZiel, single-digit and sub-zero temperatures mean all hands are on deck as problems are bound to arise.

“We all think about changing the oil in our cars all the time. Ovens and air conditioners also need attention, ”said Mike.

An old oven filter is a common problem that can shut down an oven, but it’s also a simple solution.

“If the filter is clogged, the stove cannot breathe and switches off. It will damage the heat exchanger, ”said Jeff Axelson, installation manager.

Axelson will also spend the coming days inspecting exhaust pipes when the weather gets cold enough.

“What happens is that the exhaust fumes escape and ice accumulates overnight that seals it off. So there is no heat when you wake up in the morning, ”said Axelson, adding that a screwdriver can clear up the ice.

Year-round maintenance checks can help avoid a cold wake-up call. For Jeff, the rewarding part is giving warmth back to families who deal with the cold.

“I’ve been doing this for 20 years. I love it, ”said Axelson.
