The Pro’s Advice

“What you can do to help your heater last longer.”

01

The October Test Run: Turn on your heat in late October for 15 mins to burn off dust before you actually need it.

02

The Blue Flame Rule: Gas burners should be steady and blue. A yellow/orange flame is a sign of unsafe combustion.

03

The Filter Flip: Heating requires higher airflow than cooling. Swap a fresh filter before the first freeze.

04

Clear the Unit: Ensure fallen leaves or pine needles aren't burying your outdoor unit, which causes it to freeze over.

Questions?

“Everything you need to know about keeping your home comfortable.”

Dust settles on the heating elements during the 9 months it sits idle. This 'burns off' during the first run. If the smell lasts longer than 30 minutes, call us immediately.

Always use 'Auto'. In 'On' mode, the fan pulls in unheated humid air, creating a chilly 'wind chill' effect when the furnace cycle ends.

Occasional frost is normal for heat pumps in low temps, but if it's a solid block of ice, your defrost board is likely broken, costing you a fortune in backup electric heat.

It is a backup electric heater. It uses 3 to 4 times more electricity than your heat pump. If this light stays on constantly, your system needs a professional diagnostic.

Yes. If you have any gas appliance, a CO detector is a life-safety requirement. Because our furnaces sit idle, they are prone to rust-through cracks that leak CO.

You likely have leaky attic ductwork or burnt-out electric heat strips. We can perform a thermal check to find the source of the heat loss.
