Winter HVAC Social Media Posts: What to Post in December, January, and February

By TradeFlow Editorial Team · Published 2026-10-27

Winter is when an HVAC company's phone rings whether it posts or not. So the job of winter HVAC social media posts is different from the rest of the year: not to create demand, but to make sure that when the furnace quits at 6 a.m. on a Saturday, the homeowner already knows your name, already trusts you, and can find your number in ten seconds. This post gives you 24 winter posts, sorted by month, with example captions you can adapt, and the two rules that keep a winter page useful instead of noisy.

If you followed a fall plan, you already covered furnace startup, tune-up offers and the first cold snap. Our fall HVAC social media posts guide has those. Winter picks up where that leaves off: deep cold, storms, holidays, the heat pump questions, and the quiet weeks in February when next year's work gets booked.

Two rules for a winter calendar

Post before the cold snap, then again during it. The forecast is your content calendar. When the ten-day outlook shows a deep freeze, the post about checking your furnace vents goes up two days before, and the post about your emergency line goes up the morning it hits. A great post a week late is just a post.

In winter, safety beats offers. Home heating fires peak from December through February, according to the National Fire Protection Association, which counts an average of 38,881 home heating equipment fires a year in the U.S. A company that spends the coldest weeks telling people how to stay safe looks like the company you call. A company that spends them pushing discounts looks like it needs the work.

December: deep cold and the holidays

1. Snow and your furnace vents. Most high-efficiency furnaces breathe through two white PVC pipes on an outside wall. Snow packed into the intake can block it or trip the safety switches, and the furnace will not start. This is the most useful winter post most HVAC companies never write, and it saves your techs a wasted trip.

Example caption: Before you call us about a furnace that won't start after a snowstorm, check outside. See those two white pipes on the side of the house? If snow has drifted over them, clear it gently by hand and give the furnace a few minutes. Still nothing? Call us, we're on it.

1. Space heater safety. Space heaters and heating stoves account for 29% of home heating equipment fires, per NFPA. The U.S. Fire Administration's rules are short enough to fit in one post: at least three feet from anything that can burn, and plugged straight into a wall outlet, never an extension cord or power strip.

1. Generators and carbon monoxide. Winter storms mean power outages, and outages mean generators. The CDC says to run them outdoors and more than 20 feet from windows, doors and vents, never in a garage, even with the door open. Pair it with a reminder to check CO detector batteries. The CDC counts more than 400 deaths and more than 100,000 emergency visits a year from unintentional CO poisoning, so this post is not filler.

1. Your holiday schedule, exactly. Not "we're here for you this season." The actual hours for December 24 through January 1, the on-call number, and what counts as an emergency. Pin it.

1. The heat pump steam post. The first time a homeowner sees steam pouring off their heat pump, they assume it is on fire. It is almost always a defrost cycle. Trane describes the normal signs: steam, the outdoor fan stopping, a swooshing sound, all for about three to five minutes.

Example caption: Steam coming off your heat pump on a cold morning? That's normal. It's melting the frost off its outdoor coil, and it usually takes a few minutes. Call us if it's defrosting constantly, if the cycles keep getting longer, or if ice is spreading across the whole unit.

1. Meet the on-call tech. One photo, one name, one line about how long they have been in the trade. The homeowner who calls at midnight wants to know a person is coming, not a logo.

1. Leaving town for the holidays. Turn the heat down, not off, and ask a neighbor to check on the house if a hard freeze is coming. Invite people to ask you for the right setting for their home rather than posting one number for every house.

1. A maintenance plan as a gift. For the adult kids shopping for parents who have everything. Keep it to what the plan includes and what it costs. No countdown timers.

January: the coldest weeks

January is when your page does its real work. Most of what you post should help someone right now, in a cold house, on their phone.

1. "No heat? Check these first." Thermostat set to heat and batteries alive. Furnace switch on and breaker not tripped. Filter not packed solid. Vent pipes outside clear of snow. Four checks, then call. Homeowners appreciate a company that saves them a service fee when the fix is a battery.

Example caption: No heat this morning? Four quick checks before you call: thermostat on heat with fresh batteries, furnace switch on and breaker not tripped, a filter that isn't solid gray, and vent pipes outside clear of snow. Still cold? Call us and we'll get someone out.

1. The heating bill post. January bills land in late January and early February. The U.S. Department of Energy says setting the thermostat back 7 to 10 degrees for 8 hours a day, while you are asleep or away, can save as much as 10% a year on heating. That is the most shared kind of post: useful, specific, and free.

1. Check the filter, again. The furnace has run nearly nonstop for weeks. A photo of a fresh filter next to a January one says more than a paragraph.

1. When frost on the heat pump is a problem. The follow-up to post 5. Some frost is normal; a unit encased in ice is not. Show what each looks like, and say what to do: call, do not chip at it.

1. One real winter call, told well. The 2 a.m. no-heat call, the cracked part, the family back to warm by breakfast. Ask the homeowner before you post it, and leave out the address. This is your most credible post of the season because it is true.

1. "Why is one room always cold?" A common winter complaint with real answers: closed or blocked registers, duct problems, a room over the garage. Explain what you check. It positions you as the company that figures things out, not just swaps parts.

1. Annual service, stated plainly. The CDC recommends having your heating system serviced by a qualified technician every year. That one sentence, credited, makes a stronger case for your maintenance plan than any promotion. New Year is when people sign up for things.

1. A winter review roundup. Three short quotes from Google reviews left after winter calls, first names and neighborhoods only. If the reviews are thin, our review request templates fix that in a week.

February: the long tail of winter

By February the calls slow down in most markets, the shop has a little room, and homeowners who limped through January are thinking about whether to do it again next year.

1. Repair or replace, planned. If the furnace needed three calls this winter, February is the month to price a replacement, not next December. Say why: better scheduling, no emergency pricing pressure, time to compare options.

1. Rebates and financing, if you offer them. Link to the utility rebate page for your area and explain your financing in two lines. Only post what is real and current in your market.

1. Behind the scenes in the slow weeks. Training day, a new truck, the warehouse restock. February is when your crew is in the shop, so show them.

1. A light holiday post. A warm house on Valentine's Day is a fine joke for an HVAC page. One a month is plenty.

1. Book your spring AC check now. Early openings, real dates. The homeowner who books in February does not call in a panic in June.

1. "Questions we got all winter." Five quick answers to what your office heard most. You already know the questions. This post writes itself and keeps working for months.

1. Thermostat upgrade post. What a programmable or smart thermostat actually does, who benefits, and what you install. Tie it back to the setback savings in post 10.

1. The winter wrap-up. How many no-heat calls you ran, the most common cause, and what would have prevented it. Use your own numbers. Then thank the techs who worked the coldest nights, by name if they are happy to be named.

How to actually get these posted

Winter is the worst season to fall behind on social, because your crew is busiest exactly when the posts matter most. Three ways to keep it running, from least to most effort:

1. Write December's posts in November. The holiday schedule, space heater safety and generator posts do not depend on the weather. Schedule them early so the only posts left are the ones that should be timed to the forecast.

1. Keep three forecast posts ready to go. The vent-pipe post, the no-heat checklist and your emergency line. Write them once, save them, and post the right one the day before a storm hits. When the forecast changes, you are ready in a minute.

1. Let software keep the calendar. If you want to write captions yourself, our free 10-prompt starter pack, including a prompt that captions a whole month at once, is at runtradeflow.com/prompts. If you would rather not build the calendar by hand, runtradeflow.com reads your website and drafts a month of posts that follow the season, using your job photos when you have them. Nothing publishes until you approve it, and the 7-day free trial takes no credit card.

For the quiet stretch after winter, our guide to HVAC slow season marketing covers how to fill the schedule, and if your crew rarely remembers to take photos, see what to post when you have no job photos.

FAQ: winter HVAC social media posts

What should an HVAC company post in the winter? Safety and help first: furnace vent checks after snow, space heater and generator safety, carbon monoxide reminders, a no-heat checklist and a clear emergency line. Then the human posts, like your on-call tech and real winter calls, and in February, posts that book next season's work. The 24 ideas above are sorted by month.

Should an HVAC company run promotions in winter? Lightly. Most winter calls come from need, not from offers, and safety posts build more trust in the cold months. Save promotion for the slower weeks in February, like spring AC check openings and replacement planning.

How often should an HVAC company post in winter? Two or three times a week, with room to post the day a storm or deep freeze arrives. Consistency matters more than volume. For the numbers behind that, see how often a contractor should post.

Is a heat pump steaming in winter normal? Usually, yes. It is the defrost cycle melting frost off the outdoor coil, and it typically lasts a few minutes. It is worth a call if the unit defrosts constantly, the cycles keep getting longer, or ice spreads across the whole unit. That makes a good post on its own, because homeowners search for it the moment they see it.
