The HVAC Seasonal SEO Calendar: Mapping GBP Posts and Content to AC and Heating Demand
HVAC is the only home-service trade we run where demand doesn't just rise and fall, it flips polarity twice a year. A plumber's phone rings on roughly the same cadence in April and October. An HVAC company's phone goes from 'AC not cooling' panic calls in a July heat wave to near silence in October to 'furnace won't turn on' the first hard cold snap in November. If your Google Business Profile posts, service pages, and review pushes are running on a flat 'post twice a month about HVAC' schedule, you're landing your best signals weeks after the money already moved.
The fix isn't more content. It's timed content. Google's local algorithm rewards freshness and engagement that lines up with what people in your metro are actually searching right now, and searchers move in predictable waves you can set a calendar to. This guide turns HVAC's bipolar demand curve into a concrete 12-month cadence: what to post, what to refresh, and when to push reviews, each timed roughly six weeks ahead of the spike so you're already ranking when the intent arrives. This is the planning tool, not the whole strategy.
The full local-SEO picture for HVAC is in our HVAC local SEO guide, and the review push this calendar schedules is only worth running against real numbers — ours are published in the HVAC review velocity benchmarks. Seasonal trades outside HVAC face the same six-week lead time; the landscaping version of this argument is what to do with SEO over winter.
Why six weeks ahead, not the week of
The instinct is to post about AC repair when it gets hot. That's already too late. Across the HVAC accounts we track, a freshly published or refreshed page doesn't hit its ceiling ranking the day it goes live, it climbs for four to six weeks as Google recrawls, re-evaluates, and watches early click and call behavior. If you refresh your 'AC not cooling' service page the morning of the first 95-degree day, you're competing at your weakest just as demand peaks.
So we work backward from the spike, not forward from today. In most US metros the first sustained cooling-demand surge lands mid-to-late May. That means the AC content and the GBP push start in early April. The heating flip usually arrives with the first hard freeze in late October or early November, so the furnace content starts mid-September. The two shoulder seasons, March-April and September-October, are your setup windows, not your quiet months. That reframe alone changes how most contractors staff their marketing.
One practitioner note: the six-week lead only works if the page already exists and has some history. Spinning up a brand-new 'emergency AC repair [city]' page in April from scratch will not rank by June in a competitive metro. Build the page a full season ahead, let it age, then refresh and push it into the spike.
The intent shifts you're actually planning around
Generic advice says 'post seasonally.' That's useless because it doesn't name what the searcher's problem is at each point in the year. HVAC search intent isn't one curve, it's a relay handoff between three distinct problems, and each one wants a different page and a different GBP post.
The cooling-emergency window (roughly May-August) is dominated by 'AC not cooling,' 'AC blowing warm air,' 'AC frozen,' and 'emergency air conditioning repair near me.' These are same-day, high-panic, price-insensitive searches. The heating-emergency window (roughly November-February) swaps to 'furnace not turning on,' 'no heat,' 'furnace blowing cold air,' and 'heater smells like burning.' Same panic energy, opposite system. Then the two shoulder seasons carry a completely different, calmer intent: 'AC tune-up,' 'furnace maintenance,' 'HVAC inspection,' and increasingly 'indoor air quality,' 'air purifier installation,' and 'duct cleaning.' That IAQ intent has been climbing every year on the accounts we watch, and it's the one most contractors under-serve because it doesn't feel like an emergency.
The reason this matters for SEO: the emergency pages win on speed-and-proximity signals (reviews, response, 'open now'), while the maintenance and IAQ pages win on depth and reassurance (process, pricing transparency, what's included). You cannot optimize both with the same page or the same post cadence.
The 12-month cadence, spike by spike
Here's the actual calendar we run, anchored to a typical northern-US metro. Shift it two to four weeks earlier in the South where cooling demand starts in April and heating barely registers.
January-February (heating peak, in-market): Publish weekly GBP posts on no-heat emergencies, frozen pipe prevention, and 'why is my furnace short-cycling.' Push reviews hard right now, every completed furnace call is a five-star opportunity while the customer is grateful and warm. March: The heating-to-shoulder handoff. Refresh the furnace-maintenance and IAQ pages, start GBP posts on tune-ups and 'get ahead of allergy season' air quality. April: The critical AC setup window. Refresh every cooling service page, add current-year pricing, publish 'schedule your AC tune-up before the rush' posts. May-June: Cooling ramp. Flip GBP posts to emergency-cooling intent, 'AC not cooling? here's what to check,' and push AC reviews aggressively. July-August: Cooling peak, in-market. Weekly emergency posts, respond to reviews within hours, keep 'open now' and response time flawless. September: The AC-to-heating handoff, mirror of March. Refresh furnace and heating pages now. October: The critical heating setup window, mirror of April. 'Book your furnace inspection before the first freeze.' November-December: Heating ramp into peak, flip to no-heat emergency intent and start the review push again.
The pattern is symmetrical: two setup months (April, October), two peak-and-harvest stretches (summer, winter), and two handoff months (March, September) where you quietly rebuild the pages for the season that's coming, not the one that's ending.
GBP posts: match the format to the season's intent
A GBP post isn't a blog teaser, it's a freshness-and-intent signal Google reads and a click-driver the searcher sees. In the emergency windows, we run 'What's Happening' or offer-style posts with a hard CTA, 'AC out? We're dispatching today, call now,' because the searcher is in crisis and wants a phone number, not education. In the shoulder seasons we switch to value posts, 'What a $99 AC tune-up actually includes' or 'Three signs your furnace won't make it through winter,' because the searcher is comparing and reassurance closes them.
One thing we see repeatedly: contractors who keep posting summer AC content into October because it's still in the scheduler. Google is fine with it, but the searcher isn't, and the click-through drop is real. Set post expiration to the season and rebuild the queue at each handoff month. The half-hour it takes to clear the queue in March and September is worth more than most people's entire paid-post budget.
Photos matter more than the caption in these posts. A real photo of your tech at a job site that week beats stock every time, and it quietly reinforces the 'active, local, real' signal that props up the whole profile. Bank a batch of seasonal job-site photos during each peak so you're never posting a snow photo in July.
Timing the review push to the demand you just served
Reviews are the single biggest lever on emergency-intent rankings, and the mistake is treating them as a steady drip all year. The smarter play is to concentrate the ask right after each peak's service volume. You did 40 furnace calls in January, that's 40 warm, grateful customers, ask every one of them within 48 hours of the repair. A cluster of fresh five-star reviews landing in late January doesn't just help winter rankings, it seasons the profile going into the spring setup window.
The seasonal angle most people miss: ask for the review with the season in the request. 'If we got your heat back on fast, a quick line about that would mean a lot' gets you a review that literally contains 'heat,' 'furnace,' 'no heat' keywords, which then reinforces your heating-intent relevance in exactly the window you want it. Do the same in summer with cooling language. Over a year this quietly builds a review corpus that's balanced across both demand poles instead of skewed to whichever season you happened to focus on.
One caution from the accounts we run: don't let the review velocity flatline in the off-peak. A profile that gets 15 reviews in July and zero in September looks spikier than Google likes. Keep a baseline ask on every maintenance call in the shoulder months so the curve has a floor, then concentrate the volume at the peaks.
Building the cadence into a system you'll actually run
The reason most HVAC seasonal plans die is that they live in someone's head and collapse the first busy week. Put the whole thing in a shared calendar with two recurring triggers per year per asset: a 'refresh' date six weeks before each spike and a 'flip GBP queue' date at each handoff. That's roughly eight calendar entries total. Eight reminders a year is the difference between ranking ahead of the wave and chasing it.
Tie it to weather, not just the calendar date. The date gets you 90% there, but a metro can get a freak 100-degree week in early May or a warm November that delays the heating rush. Watch the 10-day forecast around each setup window and pull the trigger a week early if the spike is coming early. The contractors who win the emergency searches are the ones whose pages were already climbing when the anomaly hit.
And remember this calendar is the operational layer, not the whole strategy. It assumes you've already got the foundation right, correct categories, complete service list, a solid site architecture with distinct cooling and heating pages. If any of that is shaky, the timing won't save you. Get the full build sequence from the hub guide at our main guide, then run this calendar on top of it.

FAQ
Frequently Asked Questions
How far ahead should I really start posting for AC season?
Start six weeks before your metro's first sustained heat, which in most northern US markets means early April for a mid-to-late May cooling surge, and March in the South. Pages climb for four to six weeks after a refresh, so the goal is to be near your ceiling ranking the day demand actually spikes, not to start climbing then. The setup work is the shoulder-season job, not the peak-season job.
Should I delete my AC service pages in winter and heating pages in summer?
No. Never take a service page down for the off-season. It kills the page's ranking history and you'll have to rebuild it from scratch every year, which in a competitive metro means it won't rank in time. Keep both cooling and heating pages live year-round, and simply refresh and re-emphasize whichever one matches the coming season. Off-season, a heating page still catches early-planning and maintenance searches.
How often should I publish GBP posts through the year?
Weekly is the cadence we run on active HVAC accounts, but the content flips with the season: hard-CTA emergency posts during the summer and winter peaks, value and maintenance posts during the March-April and September-October shoulders. The consistency of posting matters as a freshness signal, but matching the post's intent to what people are searching that month is what drives the clicks and calls.
When is the best time to ask HVAC customers for reviews?
Within 48 hours of the completed repair, concentrated right after each demand peak when you have the most grateful customers at once. Ask with seasonal language, 'if we got your heat back on fast, mention that,' so the review text carries heating or cooling keywords that reinforce your relevance in that exact window. Keep a smaller baseline ask running through the shoulder months so your review velocity never flatlines.
What's the difference between the shoulder-season and peak-season SEO play?
Peak season (summer and winter) is a harvest play: emergency-intent GBP posts, fast review responses, flawless 'open now' and response-time signals, because searchers are in crisis and pick on speed and proximity. Shoulder season (spring and fall) is a setup-and-nurture play: refresh next season's pages, run maintenance and indoor-air-quality content, and build depth and pricing transparency, because those searchers are comparing and planning rather than panicking.
Does indoor air quality content really belong in an HVAC SEO calendar?
Yes, and it's the most under-served intent we see. IAQ searches, air purifiers, duct cleaning, whole-home filtration, climb every year and peak in the shoulder seasons when neither AC nor heating emergencies dominate. They fill the calmer March-April and September-October windows with commercial intent that carries higher margins and less price pressure than emergency repair. Building IAQ pages and posts into your handoff months keeps you visible and earning in the stretches where emergency demand goes quiet.
