A local heating and cooling company has shared this:
Monday night through Thursday we all will experience temperatures and wind chills that our homes' heating systems are NOT designed for. -20 to -30-degree temperatures with wind chills into -40 and up to -50+.
Newer homes will struggle to maintain temperature and older homes will NOT maintain temperature and the temperature WILL drop while the heating system is working at full capacity.
1. Please raise the temperature in your home on Monday, 2 to 4 degrees above your normal setting. 2. Take all programmable thermostats out of setback mode and set on a permanent HOLD. 3. If you have a furnace; replace the filter. 4. Keep garage doors closed. 5. Limit opening exterior doors. 6. Make sure air vents and radiators are not blocked or obstructed. 7. If you have a 90%+ furnace and boiler: You must keep the intake and exhaust clear of ice and snow. During these cold temperatures, ice can build up. A 90%+ furnace and boiler have 2 white PVC pipes; an exhaust pipe and an intake pipe that are generally on the side or back of your home. In some instances, they are on your roof, do NOT go on your roof to clear the pipe.
If the temperature in your home is dropping and your radiators are HOT with boiler systems or you have HOT air coming out of your vents with furnaces DO NOT PANIC. Please make sure that your heating system continues to operate.
If the temperatures drop in your home, it will not be able to recover until temperatures rise and the windchill diminishes. Our heating systems cannot overcome temperatures -20 to -30 with wind chill up to -50+. They are sized to operate at 0 degrees outdoor. Put your thermostat on hold 70 degrees or higher.
To help minimize temperature loss you can boil water, make soup, or stews; they help introduce humidity and warmer temperatures into your home. DO NOT USE YOUR OVEN or a GRILL TO HEAT YOUR HOME.
Please check on neighbors and elderly residents during these extreme temperatures.
Governor Gretchen Whitmer signed an order last night declaring a state of emergency in Michigan ahead of the forecast sub-zero temperatures. "The statewide emergency declaration means state agencies are working more closely with local communities and emergency management agencies to ensure adequate resources are available to take care of residents." "Conditions and needs will be continually assessed, and appropriate action will be taken as warranted to protect public health and safety. " At this time, there are no mandates for residents to stay off the roads, or remain indoors, etc..
