TL;DR
Social media produces HVAC calls three ways, and none of them is a daily posting schedule. First, as a review surface: 36 percent of homeowners check Facebook for contractor reviews, behind Google at 56 percent and your own website at 51. Second, as the place referrals happen: 26 percent of homeowners hired their last HVAC company on a personal recommendation, and a growing share of those recommendations are typed into a neighborhood Facebook group or Nextdoor, which one in three US households now uses. Third, as a paid channel for the cheap lead: a Meta lead-gen campaign in the home improvement category ran $42.95 a lead in 2026 against $190 to $335 for an HVAC lead on Google Ads, with the catch that the Meta lead is a tune-up or maintenance-plan inquiry, not a no-heat call. Everything else, the platform list, the 5-to-7-posts-a-week advice, the TikTok tutorials, is where the money goes to look busy. Only 1.8 percent of homeowners said they chose a company because they saw an ad.
Every HVAC social media guide opens with a list of platforms and their user counts. Facebook has two billion people on it, so you should be on Facebook. That is not an argument; it is a census. The question a contractor is asking is which of the platforms will ring the phone, and the surveys that exist answer it fairly clearly, so this guide starts there and works back to what to post.
This is the social side only. The full channel ranking is in how to get HVAC leads, the search side is in the HVAC SEO guide, and the broader idea list is in HVAC marketing ideas.
How homeowners actually pick an HVAC company
FIELDBOSS surveyed 1,000 US homeowners who had hired an HVAC company in the previous year, in July 2025. 42.6 percent went back to a company they already knew. 26.3 percent went on a recommendation from a friend or family member. 17 percent found the company through an online search. 7.7 percent used online reviews or a marketplace app. 1.8 percent chose a company because they saw an advertisement. Repeat and referral together are about 69 percent of the market, and there is no social media line, because social media is not a channel to these homeowners. It is where the referral and the review happen.
The ACHR News survey of 400 homeowners in 2024 lines up: 73 percent contacted the same company they used before, 67 percent found their contractor by word of mouth "including social media", and 91 percent rated online reviews as important. Where they read those reviews is the useful part. Google 56 percent, the contractor's website 51 percent, Yelp 43 percent, Facebook 36 percent, Angi 32 percent. Facebook is the fourth review surface in HVAC, which is a stronger position than most contractors give it.
| How the last HVAC company was chosen | Share of homeowners |
|---|---|
| Returned to a company they already knew | 42.6 percent |
| Recommendation from a friend or family member | 26.3 percent |
| Online search | 17.0 percent |
| Online reviews or a marketplace app | 7.7 percent |
| Home warranty, insurer or builder referral | 4.0 percent |
| Saw an advertisement | 1.8 percent |
| Verdict | Social earns its keep as the place recommendations and reviews live, not as an ad channel. Build for that. |

Which platforms your customer is on
The HVAC buyer is a homeowner between 30 and 65, and Pew's November 2025 survey of 5,022 US adults says where that person is. Facebook is used by 80 percent of 30-to-49-year-olds and 74 percent of 50-to-64s, and it is the one platform where the 30-to-49 group is the peak, not the young. 58 percent of 30-to-49s are on it daily. YouTube is higher still, 92 percent and 85 percent, but people go there to learn, not to hire. Instagram drops to 62 and 40 percent. TikTok is 44 and 30 percent, and 12 percent over 65. Nextdoor sits at about 13 percent of adults in Pew's last count, 17 percent in cities and 14 percent in suburbs, and Nextdoor's own figure is one in three US households.
That is the whole platform decision. Facebook, because the customer is there daily and reads reviews there. Nextdoor, because that is where the "anyone know a good HVAC guy" post gets written. YouTube as a search engine for the questions homeowners ask before they call. Instagram if you have a photographer on the crew. Nothing else until those four are done, and the fourth is optional.
The three things that produce calls
1. Being the answer in the group
The 26 percent of homeowners who hired on a recommendation increasingly got that recommendation in public: a neighborhood Facebook group, a Nextdoor thread, a town page. Nextdoor's August 2026 report, which it commissioned, so read the ranking with that in mind, says 79 percent of neighbors who did a home maintenance task that year used Nextdoor at some point, and nine in ten said neighbor recommendations influenced who they chose. The work is unglamorous. Claim the Nextdoor business page and ask every happy customer for a recommendation there, the same way you ask for a Google review. Join the six or eight local groups your service area covers and answer questions when they come up, by name, without pitching. A contractor who has answered "why is my furnace short cycling" in the Maple Grove Moms group four times is the one who gets tagged when someone asks for a recommendation in December. The review playbook covers the ask; the ask just has two more destinations now.
2. Reviews on Facebook, because 36 percent look there
Your Facebook page is a review site for a third of your customers. Recommendations turned on, the last twenty answered, the profile photo a truck and not a logo, hours and phone correct, and a post at least once a fortnight so the page does not look abandoned to the person checking it at 9pm before they call in the morning. That is the entire organic Facebook program for most companies, and it takes an hour a month. The daily posting schedule in the other guides is for agencies with a content quota to fill.
3. Paid Meta for the cheap lead, in the right season
Meta lead ads are the one place social competes with search on price. LocaliQ's 2026 benchmark puts a lead-generation campaign in the home and home improvement category at $42.95 a lead, a 5.32 percent conversion rate and a $2.18 click. 99 Calls' HVAC Google Ads data for the same year puts a search lead at a median of $190 to $335 and an average of $262. The Meta lead is five to eight times cheaper, and the reason is that it is a different lead: someone who saw a $79 tune-up offer while scrolling, not someone whose heat is out. Agency-published ranges for HVAC Meta leads by type make that plain: $25 to $55 for a tune-up, $40 to $80 for a maintenance plan, $150 to $275 for a system replacement estimate, and 25 to 60 percent higher outside peak season. One agency comparison puts the close rate on a Meta lead at about 12 percent against 40 percent on a Google Ads lead. The arithmetic still works, a $50 lead at 12 percent is $415 per booked tune-up that leads to the replacement, but only if the offer is a tune-up or a plan and the campaign runs in March and September, when nobody is searching and everybody is scrolling. We run Meta bundled with search at $1,000 a month or 15 percent of combined spend, published on the paid ads page, and the mechanics are in Facebook ads for contractors.

Want the shoulder-season Meta campaign built and the review asks wired in?
We run the profile, the review system and the paid social alongside the search work, at published prices with no contract. The first call is thirty minutes and ends with a plan for which of the three above is worth your time.
What organic posting is for, and how much of it
Organic posts do not rank you. Whitespark's 2026 survey of 47 local search experts puts "frequency of Google posts" at 186th and "quantity of Google posts" at 187th on the list of local ranking factors, and social signals at about 2 percent of the local pack. Posting does two smaller things: it keeps the page alive for the reviewer at 9pm, and it gives the group member who was about to recommend you something to link. Two posts a week does both. FieldEdge's guide says five to seven a week on Facebook and daily on Instagram; for a company with an office manager and no marketing hire, that advice produces three weeks of effort and a dead page in month two.
The posts that get shared are the ones that answer a question the neighborhood is asking that month. Here is a year of them, two a month, built around when HVAC demand actually moves. Every one can be a photo from a truck and four sentences.
| Month | Post one | Post two |
|---|---|---|
| January | What a no-heat call costs after hours, and the three things to check before you make one | A technician on a furnace job, named, with the temperature outside |
| February | Why the furnace short-cycles when it is below zero | The oldest furnace you replaced this month, with the year on the label |
| March | Spring tune-up offer with the price and the date it ends | A customer review, screenshot, with a thank-you |
| April | Filter reminder with the size chart | Before and after of a coil cleaning |
| May | What an AC tune-up actually includes, as a checklist | The crew, the trucks, the first hot week |
| June | Why the AC freezes up, and what to do before you call | Maintenance plan explained in four lines with the annual price |
| July | The heat wave post: what the response time is today, honestly | A heat pump install with the electric bill difference the customer reported |
| August | Rebates and tax credits still open this year, with the deadline | A five-year-old review reposted with "still running" |
| September | Fall furnace tune-up offer with the price | Carbon monoxide detector reminder with the battery date |
| October | What a furnace inspection found this week, photo of the cracked heat exchanger | Thermostat setting post for the first cold night |
| November | Holiday hours and the emergency number | The year in reviews, with the count |
| December | Space heater safety, the honest version | A thank-you to the neighborhood groups that referred customers this year, by name |
Pro tip
Put the technician's first name in the photo posts. The referral in the group is almost never "call ABC Heating"; it is "ask for Dave at ABC, he fixed ours in an hour". A page full of logos gives the neighbor nothing to say.
YouTube, separately
YouTube is on 92 percent of 30-to-49-year-olds and 85 percent of 50-to-64s, and it is the second-largest search engine, which is the point. Nobody subscribes to an HVAC company. They search "why is my AC blowing warm air" at 11pm in July and watch whatever comes up, and a two-minute phone video from a technician in front of the unit, with the company name and city in the title, ranks for that search in most metros because nobody local has made one. Eight videos, one per common failure, filmed on real jobs over a summer, and then leave them alone. That is the whole YouTube program, and it feeds the search side more than the social side.
Three to skip
The platform-a-day plan. A company posting to Facebook, Instagram, TikTok, LinkedIn and X on a schedule is producing content for five audiences, four of which do not hire HVAC companies there. Facebook and Nextdoor, then YouTube if you have a technician who can talk to a phone.
Boosting posts. The $20 boost button buys reach from people who are not in the market, at a cost per anything that nobody measures. If the money is going to Meta, it goes to a lead-gen campaign with an offer and a form, in shoulder season, tracked to a booked job.
Paying an agency for a posting calendar. A social retainer that delivers twelve branded graphics a month and a reach report is the most common wasted line item in HVAC marketing. If the report does not show recommendations, reviews and booked tune-ups, the work is not the work described above. The HVAC agency roundup covers who sells what.

Frequently asked questions
Does social media marketing work for HVAC companies?
Three parts of it do. Facebook is a review surface for 36 percent of homeowners, neighborhood Facebook groups and Nextdoor are where the 26 percent of hires that come from recommendations increasingly happen, and Meta lead ads for tune-ups and maintenance plans run about $43 a lead in the home improvement category against $262 for an HVAC lead on Google Ads. Organic posting on its own does not produce calls: only 1.8 percent of homeowners chose their last HVAC company because they saw an ad.
Which social media platform is best for HVAC companies?
Facebook, then Nextdoor. Pew's 2025 survey puts Facebook at 80 percent of 30-to-49-year-olds and 74 percent of 50-to-64s, with 58 percent of the younger group on it daily, and 36 percent of homeowners check it for contractor reviews. Nextdoor reaches one in three US households and is where neighborhood recommendation requests get posted. YouTube works as a search engine for repair questions rather than as a social channel. Instagram and TikTok reach the HVAC buyer far less.
How often should an HVAC company post on social media?
Twice a week on Facebook is enough, timed to the season: tune-up offers in March and September, filter and thermostat reminders, technician photos with names, and reposted reviews. Posting frequency ranks 186th among local search ranking factors in Whitespark's 2026 expert survey, so the purpose of posting is to keep the page alive for the homeowner checking it before they call, not to rank. Five to seven posts a week is agency advice that a small company cannot sustain and does not need.
How much do HVAC Facebook ads cost per lead?
LocaliQ's 2026 benchmark puts a lead-gen campaign in the home and home improvement category at $42.95 a lead with a 5.32 percent conversion rate and a $2.18 cost per click. Agency-published HVAC ranges run $25 to $55 for a tune-up lead, $40 to $80 for a maintenance plan and $150 to $275 for a replacement estimate, rising 25 to 60 percent outside peak season. Close rates on Meta leads are reported at roughly 12 percent against 40 percent for Google Ads leads, so the cheap lead needs a maintenance offer behind it.
Should HVAC companies use Nextdoor?
Yes, as a recommendation surface rather than an ad platform. Claim the business page, ask satisfied customers for a Nextdoor recommendation alongside the Google review, and answer questions in your service area's threads by name. Nextdoor's own 2026 report, commissioned by Nextdoor, says 79 percent of neighbors doing a maintenance task used it that year and nine in ten were influenced by neighbor recommendations; the neutral figure is Pew's, that about 13 percent of US adults use it, concentrated in cities and suburbs.
Is it worth hiring an agency for HVAC social media?
Only if the agency runs the paid Meta campaign, wires the review and recommendation asks into your job completion process, and reports booked jobs. A retainer that delivers a posting calendar and a reach report is the most commonly wasted line in HVAC marketing. Skill Mammoth runs Meta bundled with search at $1,000 a month or 15 percent of combined spend, published on its paid ads page, alongside the review system and the search work.
