Common questions

Why is my furnace running but blowing cold air?

Common causes include a thermostat fan set to ON, a clogged air filter, a dirty flame sensor, a failed igniter, or snow blocking the vent pipes on a high-efficiency furnace. Check the thermostat, filter and vent pipes, then call for service if the problem continues.

What should I check before calling for furnace repair?

Make sure the thermostat is set to HEAT, replace a dirty filter, confirm the furnace switch and breaker are on, and clear snow from outdoor vent pipes. Do not open the burner compartment or bypass safety switches.

Is it safe to run my furnace if it smells like gas or my CO alarm goes off?

No. Leave the house right away, do not use light switches or phones inside, and call 911 and your gas utility from outside. Do not run the furnace again until a technician has inspected it.

Do Krinkie's Club members get a discount on furnace repair?

Yes. Krinkie's Club members receive 20% off repairs, a reduced diagnostic fee and priority service.
