Question 1

Why is my furnace running but blowing cold air?

Accepted Answer

First, check that the thermostat is set to heat and the fan is on auto rather than on, since an always-on fan circulates unheated air between cycles. A badly clogged filter can make the furnace overheat and shut its burners off as a safety measure. Other common causes include a dirty flame sensor, an ignition problem or a blocked condensate line, which typically call for furnace repair.

Question 2

What should I check before calling for furnace repair in West Bend?

Accepted Answer

Make sure the thermostat has fresh batteries and is set a few degrees above room temperature, the furnace switch and breaker are on, and the filter is not clogged. If you have a high-efficiency furnace with plastic vent pipes on the outside wall, check that snow or ice has not blocked them, which happens often during a West Bend winter. If the heat still will not come on, it is time to call.

Question 3

What do unusual furnace noises usually mean?

Accepted Answer

A loud bang when the burners light can point to delayed ignition, which should be looked at soon. Squealing often comes from a worn blower motor bearing or belt, while rattling may mean a loose panel or duct. Whistling usually signals restricted airflow from a dirty filter or closed registers. Noting when the sound happens, at startup, during the cycle or at shutdown, helps narrow down the cause.

Question 4

Is a high-efficiency furnace a good choice for Wisconsin winters?

Accepted Answer

For many homes, yes. High-efficiency condensing furnaces capture extra heat from their exhaust, so more of the fuel you pay for warms your home, which adds up over a long Wisconsin heating season. They vent through plastic pipe and drain condensate, so the installation looks a little different from an older unit. We install Rheem furnaces and can help you weigh the options during a free estimate.

Question 5

How can I protect my home from carbon monoxide from a gas furnace?

Accepted Answer

Install carbon monoxide detectors on every level of the home and near sleeping areas, and test them regularly. A properly working furnace vents its exhaust safely outside, but a cracked heat exchanger or blocked vent can let carbon monoxide escape. If a detector sounds or anyone feels dizzy, nauseous or unusually tired, leave the house right away and call 911 or your gas utility from outside.

Question 6

Can radiant floor heat work alongside my furnace?

Accepted Answer

Yes. Many homes use radiant floor heat in a bathroom, basement or addition while the furnace continues to heat the rest of the house. The two systems are controlled separately, so each area stays at its own comfortable temperature. If you are curious about adding warm floors, see our radiant in-floor heating installation service to learn how it fits with your existing heating.
