I’m in and out of homes all over OKC, Moore, Yukon, Edmond, and Mustang every winter, and I see the same preventable damage over and over — frozen pipes, no heat, cracked furnaces, and high emergency bills.

Heat Pumps & Outdoor Units During Ice Quick Oklahoma Freeze Checklist Video: Freeze Prep from a Local Tech FAQ: Oklahoma Freezes, Furnaces & Frozen Pipes What an Oklahoma Freeze Really Does to Your Furnace and Home Our Oklahoma winters are sneaky. We can be in hoodies one day and waking up to ice on everything the next. Those fast swings are hard on both your home and your heating system: Your furnace has to run longer and hotter to keep up with the cold. Pipes in exterior walls, garages, and crawlspaces start flirting with freezing. Drafts around doors, windows, and attic hatches pull warm air right out of the house. Power flickers and surges can damage furnace control boards and low-voltage components. Heat pumps go into defrost more often and can ice up if they’re already struggling. Prepared OKC Home Unprepared OKC Home Furnace tuned, filter changed, thermostat checked. Furnace hasn’t been checked in years, dirty filter choking airflow. Pipes insulated, cabinets open, vulnerable faucets dripping. Pipes in exterior walls sealed up and forgotten until they freeze. Drafts reduced, curtains managed, heat staying where you need it. Cold air pouring in from gaps, rooms never warming up. Knows the main water shut-off and emergency contacts. Hunting for valves and phone numbers while water pours or heat is out. Bottom line: You can’t control the Oklahoma weather, but you can absolutely control how ready your furnace and home are when that first ice storm hits the metro. 1. Prep Your Furnace Before the Oklahoma Freeze or Ice Storm Don’t wait until there’s ice on the trees and the roads are slick to see if your furnace will fire. Here’s what I tell Oklahoma City homeowners to do early: Give your furnace a head start before the freeze. A quick check now beats an emergency call in the middle of an ice storm. Simple furnace prep steps you can do today: Change your filter. If you don’t remember the last time you changed it, it’s overdue. A dirty filter is the #1 thing I see making furnaces struggle in OKC. Turn the heat on early. Switch to HEAT and let the system run several full cycles. Listen for unusual noises, rattles, or grinding. Smell for issues. A light “burnt dust” smell for the first few minutes is normal. Strong burning, melting, or electrical smells are not — shut it down and call. Clear the area around your furnace. Move boxes, paint cans, and stored items away from the unit so it can breathe and be serviced safely. Check supply and return vents. Make sure vents and returns aren’t blocked by furniture, rugs, or boxes. High-efficiency furnaces: Check PVC intake and exhaust pipes outside and make sure they’re not blocked by leaves, debris, or old wasp nests. Pro move for Oklahoma homeowners: Book a furnace tune-up before the first big cold snap. I’ll check gas pressure, safeties, flame, blower, temperature rise, and make sure your system is safe and ready for longer winter run-times. 2. Thermostat Settings & Power Protection During a Freeze Your thermostat is the “brain” of your comfort. When the temperature drops fast in Oklahoma, small mistakes here can mean cold rooms and high bills. Smart thermostat habits can keep your family comfortable and help protect your pipes during Oklahoma ice storms. Best thermostat habits for Oklahoma freezes: Pick a temperature and hold it. For most OKC homes, 68–72°F works well during a freeze. Avoid constantly bumping it up and down. Don’t shut the heat off completely at night. Letting the house get too cold can put pipes in exterior walls and garages at risk. Heat pump owners: Make sure your thermostat is on HEAT, not accidentally set to EMERGENCY HEAT unless your tech tells you to. Emergency heat can drive bills way up. Check your fan setting. Most homes do best with the fan on AUTO, not ON, especially during long cold snaps. Change thermostat batteries. If your thermostat uses batteries, put fresh ones in before winter so it doesn’t fail in the middle of an Oklahoma ice storm. Power flickers, surges, and your furnace: Use surge protection. Ask about whole-home surge protection or at least protect sensitive electronics. Surges can damage furnace control boards and transformers. After an outage, give the system a few minutes before turning it back on so compressors and motors aren’t hit while pressure is off-balance. Watch for error codes. If your furnace flashes a trouble code after a storm, don’t keep resetting it — that’s your cue to call. From the field: A lot of “mystery” no-heat calls after Oklahoma ice storms turn out to be low-voltage problems, failed transformers,
