When your furnace stops working during a Michigan winter, start with safety, then a few simple checks. You do not need to take the furnace apart to gather useful information. If your home is losing heat, Davison Home Services provides emergency heating service in Davison and nearby communities.

First, Check for an Immediate Safety Concern
If you smell gas, hear a carbon monoxide alarm or notice smoke, leave the home and call emergency services or your gas utility from outside. Do not remain inside to inspect the furnace. Avoid operating switches or creating a flame when you suspect a gas leak.
If anyone may have been exposed to carbon monoxide, get to fresh air and seek emergency help. A furnace service appointment is not a substitute for an emergency response.
Confirm What the Thermostat Is Asking For
If there is no immediate hazard, check that the thermostat is set to Heat and that the requested temperature is above the room temperature. A changed schedule, depleted batteries or an incorrect setting can make a working furnace appear to have failed.
- Check the displayed indoor temperature and setpoint.
- Replace thermostat batteries if the device uses them and indicates they are low.
- Note any error message without clearing it.
- Check whether the problem affects the whole home or only one room.
Give the system time to respond according to its normal operation. Repeatedly changing settings or cycling power can erase information useful to the technician.
Look at the Filter and Air Vents
A restricted filter can reduce airflow and contribute to a shutdown. If the filter is safely accessible, inspect it and follow the equipment instructions for replacement. Use the correct size and type. Do not run the system without a filter as a workaround.
Make sure furniture, rugs and other items are not covering supply or return grilles. Do not remove equipment panels, bypass a door switch or reach into moving parts.
Note Power Problems Without Repeated Resets
A blank thermostat or silent furnace can involve a power issue. Check whether the home has lost electricity and note any obviously tripped breaker. Do not repeatedly reset a breaker that trips again. A recurring trip needs a professional assessment, and wet or damaged electrical equipment should be left alone.
Call for Service if Heat Does Not Return
Ignition problems, failed motors, control faults and safety shutdowns need diagnosis. Our furnace repair team can explain what failed and the proposed repair before work begins.
Have these details ready when you call:
- Your address and the best number to reach you
- How long the heat has been off and the indoor temperature
- Whether the furnace starts, blows cool air or stays silent
- Any visible error code or unusual sound
- Any recent service or repeated problems
Stay Warm Safely While Waiting
Close exterior doors and reduce unnecessary drafts. If you use a portable heater, follow its instructions, keep it away from combustible materials and never leave it unattended. Do not use a stove, oven, grill or outdoor generator to heat your home.
If the indoor temperature cannot be kept safe, arrange a warm place to stay, especially for children, older adults and anyone with health concerns. If pipes are at risk or you discover a leak, call for help rather than using an open flame to thaw a pipe.
Plan Ahead After the Repair
Once heat is restored, ask what contributed to the failure and whether follow-up is needed. Regular furnace maintenance provides an opportunity to inspect wear, airflow and operation before the next cold spell. The Davison Home Care Club includes priority scheduling and an annual HVAC health check.
