What Should an HVAC Company Post on Social Media?

Updated September 2026 · By Tracy Dang

TL;DR: An HVAC company should post the things it already explains on service calls. That means seasonal maintenance reminders, what a strange noise or smell usually means, what a maintenance agreement covers, clean install photos, and quick checks before a no-heat or no-cool call. Post two or three times a week, plus a weekly Google Business Profile post. Plan your seasonal posts four to six weeks before each peak season.

Key takeaways

Post what you already explain on the phone. A dirty filter, a strange noise, what a tune-up includes. Every one of those is a post, and none needs a photoshoot.
Seasonal timing matters most. Post maintenance reminders four to six weeks before summer and winter, so you're top of mind before the first heat wave or cold snap.
Google Business Profile comes first. "AC repair near me" searches land on the map, so your hours, reviews, and recent posts there are what homeowners check.
Use the shoulder season to get ahead. Spring and fall are quieter, which makes them the right time to set up your posting and promote maintenance agreements.
Social media builds trust; it rarely starts the job. It keeps you in front of past customers and makes you look open and active when someone compares companies.

Does social media actually help an HVAC company?

Social media rarely starts an HVAC job on its own. Most work comes from a search, a referral, or a customer who has used you before. In a FIELDBOSS survey of 1,000 U.S. homeowners who had hired an HVAC professional, most chose a company they'd already used or one a friend recommended. Only about one in six found their provider through an online search.

That doesn't make social media pointless. It changes what it's for. Posting does two jobs well. It keeps your company in front of the households that already know your truck, who are the most likely to call again. And it settles the comparison after a search. A homeowner looking at three HVAC companies on a map will check all three, and a page that went quiet last summer looks like a company that might not answer the phone. A current, helpful feed builds trust before the emergency, not during it. If finding time to post during the busy season is the hard part, that's the part Presly handles, covered near the end of this guide.

What are some good social media posts for an HVAC company?

The best HVAC social media post ideas come from the questions you answer every week. They're useful, they show you know your trade, and they don't require a photoshoot. Here are fifteen that work:

Filter reminders. "When did you last change your filter?" is one of the most useful posts an HVAC company can make.
What a strange noise usually means. Banging, squealing, clicking, or humming, one sound per post, with a clear "call us if" line.
What a tune-up includes. Walk through what you actually check on a seasonal maintenance visit.
What a maintenance agreement covers. Explain your service plan in plain words: visits per year, what's included, and why it matters.
Checks before a no-heat call. The thermostat, the breaker, the filter. Simple steps a homeowner can try before calling.
Checks before a no-cool call. The same idea for the first hot week of summer.
Clean install photos. A tidy new system from today's job, taken on your phone, with a line about the work.
Your own before-and-after work. Real photos of a unit you replaced or a ductwork job you cleaned up.
Thermostat tips. How to set a schedule, what the fan setting does, and when a smart thermostat helps.
Energy-saving tips. Simple habits that take strain off a system during peak season.
Meet the technician. A photo and a short introduction of the person who'll show up at the door.
Customer reviews, with permission. Share a review only with the customer's permission, and leave out personal details.
Your service area. A map or list of the neighborhoods and towns you cover.
Holiday and weather updates. Holiday hours, and "we're running extra crews this week" during a heat wave.
Emergency readiness. What to do if the system fails overnight, and how to reach you after hours.

Rotate through these so your feed covers your whole business: maintenance, repair, installation, and your team. A mix of tips, seasonal reminders, and real job photos keeps your page useful and shows a company that's busy and trustworthy.

When should an HVAC company post seasonal content?

Timing is what separates HVAC social media from most other businesses. Demand swings hard between seasons. By our calculation from U.S. Energy Information Administration degree-day data, combined heating and cooling demand bottoms out in September, then May, October, and April, and peaks in January and July. Those quiet months are the shoulder season.

The shoulder season is the right time to prepare. You have more time between calls, and homeowners haven't yet hit the first heat wave or cold snap. Post maintenance reminders four to six weeks before each peak, so your company is top of mind when the rush arrives. Here's a simple calendar:

| Month | What to post | |---|---| | January | No-heat checks, furnace safety, holiday-season emergency hours | | February | Filter reminders, maintenance agreement sign-ups, indoor comfort tips | | March | Spring tune-up reminders, getting ready for cooling season | | April | AC tune-up promotions ahead of summer, shoulder-season scheduling | | May | Last call for AC tune-ups before the heat, thermostat tips | | June | No-cool checks, energy-saving tips for the first hot weeks | | July | Heat-wave readiness, extra crews, peak-season hours | | August | Mid-summer system checks, filter reminders | | September | Fall tune-up reminders, getting ready for heating season | | October | Furnace tune-ups ahead of winter, shoulder-season scheduling | | November | Heating readiness, holiday hours, maintenance agreement renewals | | December | Cold-snap readiness, emergency contact info, year-end thanks |

Adjust the timing for your climate. A company in Phoenix and one in Minneapolis have very different peaks. The principle holds everywhere: post ahead of the busy season, not during it.

What is a good caption for an HVAC service?

A good HVAC caption is short, specific, and useful. It answers a real worry, sounds like a person, and ends with a helpful offer rather than a hard sell. Here are a few examples:

"Most no-heat calls we get in the first cold week are a clogged filter or a tripped breaker. Check both before you call. If it's still cold, we're here."
"Your AC works hardest in July. A tune-up in May means fewer surprises when it matters. Book yours before the rush."
"New system installed in Riverside today. Clean lines, quiet unit, happy homeowner. Here's what a proper install looks like."
"What does a maintenance agreement actually get you? Two tune-ups a year, priority scheduling, and a technician who already knows your system."

Keep captions to a few sentences. Use your own words, mention your area when it fits, and include one clear next step: call, book, or send a message.

Which platforms should an HVAC company use?

Start where homeowners search when something breaks, then add the platforms they browse the rest of the year.

Google Business Profile comes first. When a homeowner's AC dies, they search "AC repair near me" and look at the map. Your hours, reviews, photos, and recent posts there are what they judge you by, often before they see any other page. Post there about once a week. Google's own policy says Business Profile photos should represent reality, so use real photos of your crew and your work.

Facebook is where many homeowners, especially older ones, spend time and ask neighbors for recommendations. It's a strong place for seasonal reminders, reviews, and community posts.

Instagram works well for clean install photos, before-and-afters of your own work, and short tips.

You don't need every platform. A steady presence on Google Business Profile plus one or two others beats scattered posting across five.

How often should an HVAC company post?

Two or three posts a week on your main platform, plus a weekly Google Business Profile post, is enough for most HVAC companies. Consistency matters more than volume. A company that posts three times every week looks more established than one that posts ten times in May and then goes silent for the summer.

The busy season is exactly when posting slips, because the crew is out on calls from morning to night. That's why many owners write and schedule a batch of posts during the shoulder season, so the page keeps running while the phones are ringing.

What can Presly do for an HVAC company?

For an HVAC owner, the problem is rarely knowing what to post. It's that the busy season, when posting matters most, is exactly when the crew is out on calls from morning to night. Presly writes your posts and publishes them for you, so your company stays visible through the rush and the shoulder season alike.

Here's what that looks like for an HVAC company:

It writes for HVAC, not for a generic business. Presly treats HVAC as its own business type, with seasonal maintenance posts, such as spring AC tune-ups, and emergency-readiness posts.
It works from your job photos. Snap a photo of a clean install or a finished repair on your phone and upload it from your phone's browser, with no app to download. Presly writes the post to go with it.
It posts to your Google Business Profile. Your real job photos go straight to the listing homeowners check when they search "AC repair near me," alongside Facebook and Instagram, among 10 platforms.
It keeps running when you're busiest. Set your posting once and it keeps going through peak season, so your page doesn't go silent the moment the phones start ringing.
You stay in control. You can approve every post before it goes out, or let Presly post on its own once you trust how it sounds.
It helps you keep up with messages. On the Growth plan and up, messages from your accounts come into one inbox, where Presly drafts replies that you review and send. You can also answer your Google reviews from the same place.

Here's what that writing looks like. The posts below were written by Presly for Hollis Ridge Heating & Air, a sample business we made up for this guide. They're shown exactly as Presly wrote them, unedited, including the hashtags.

That burning smell when you first turn on the heat? It's normal.

> Usually, it's just the dust from a quiet summer burning off the heat exchanger. It should go away in under an hour.

> But if that smell lingers, or if you hear a rattle or clank along with it, that’s your furnace sending up a flare. It's a sign that something needs a look before it has to work hard all winter.

> A pre-season furnace tune-up is the best way to catch those little things. We can make sure everything is clean, safe, and ready for that first cold Ohio night.

> DM us 'TUNEUP' and we'll send over our schedule for a pre-season check. 🍂

That '90-day' rule for your furnace filter? It's a myth.

> It's a good starting point, but it's not the whole story. If you have pets, live on a dusty road, or have an older home, your filter could be clogged in 30-60 days. A clogged filter makes your furnace work harder, drives up your energy bill, and can lead to bigger problems. 😟

> Here's the real test: Hold your filter up to a light. If you can't see the light through it, it's done.

Presly costs $39, $79, or $159 a month (Starter, Growth, and Pro). The best way to judge it is to watch it write for you: start a 7-day trial, tell it about your company, and read the first week of posts it drafts. You can approve each one before anything goes live. The trial requires a card.

What Presly can promise is presence: a company that looks open and active when a homeowner compares you against two others. It doesn't promise calls or leads.

Frequently asked questions

What is the best way to advertise my HVAC business?

Start with the free channel homeowners use in an emergency: your Google Business Profile, with accurate hours, real photos, recent posts, and reviews. Ask satisfied customers for a Google review after each job. Add seasonal social media posts to stay in front of past customers. Paid ads can come later, once your profile looks current and well reviewed.

How to get more clients for HVAC?

Most HVAC clients come from repeat customers, referrals, and local search, so focus there first. Keep your Google Business Profile current, ask every happy customer for a review, and offer a maintenance agreement that brings customers back each season. Social media supports all three by keeping you visible and making you look trustworthy when someone compares companies.

Is HVAC becoming oversaturated?

Many areas have plenty of HVAC companies, which makes standing out harder. The companies that stand out tend to look current and trustworthy online, with recent reviews, a complete Google Business Profile, and a steady stream of helpful posts. When a homeowner compares three companies, the one with a clear, active presence is easier to choose.

What is the 5:3:2 rule for social media posts?

It's a common rule of thumb: out of every ten posts, five share useful content from others, three are your own, and two are personal. For an HVAC company, the exact ratio matters less than posting consistently. A steady mix of your own tips, seasonal reminders, and real job photos works better than a perfect ratio followed by silence.

What are some good social media posts for an HVAC company?

Post the questions you answer on the phone: filter reminders, what a strange noise means, what a tune-up includes, and quick checks before a no-heat or no-cool call. Add clean install photos, your own before-and-after work, and seasonal maintenance reminders four to six weeks before summer and winter.

Should an HVAC company post on Google Business Profile?

Yes. When a homeowner's system fails, they search "AC repair near me" and see your Google Business Profile on the map first. Keep your hours, reviews, and photos current, and post about once a week. Google says Business Profile photos should represent reality, so use real photos of your crew and your work.
