Think social media doesn’t matter for your HVAC business? Think again. Whether it’s a quick Google search or a scroll through Instagram, today’s homeowners are checking you out online before they ever pick up the phone.
And if your last post was six months ago—or worse, non-existent—you’re sending the wrong message.
For HVAC companies, social media isn’t just about going viral. It’s about building trust, showcasing your work, and staying top-of-mind when someone’s furnace fails in February or their A/C dies in July. With the right HVAC social media strategy, you can turn casual scrollers into paying customers—and keep existing ones coming back.
Not sure what to post? Don’t worry. We’ve got a full list of content ideas that will boost your heating and cooling content, improve customer engagement, and grow your business without dancing on TikTok (unless you want to).
Post Type #1 – Seasonal HVAC Tips That Show You’re the Expert
Want to stay relevant year-round? Share quick, seasonal tips that homeowners actually need—right when they need them. These posts show your audience that you’re proactive, professional, and prepared to help, no matter the weather.
In the winter, you might offer advice on preventing frozen pipes or keeping furnaces running efficiently during cold snaps. As temperatures rise, switch gears with summer-focused posts like how to reduce cooling bills or spot signs of a failing A/C unit.
You can also use spring and fall to highlight tune-ups, indoor air quality improvements, or filter reminders. These posts aren’t just helpful—they quietly remind people that you’re the one to call before a small issue becomes a costly emergency.
Pro Tip: Mention your service area in the caption to boost local visibility. A simple line like “Planning ahead for summer in New Orleans?” goes a long way.
Post Type #2 – Before & After Photos That Build Trust
Photos tell a story—and in HVAC, that story is often the difference between a breakdown and a solution. Before-and-after shots are one of the easiest ways to showcase your work while building trust with potential customers.
Whether it’s a full system install, a duct cleaning, or a rusty old furnace replaced with a sleek new unit, these posts help homeowners visualize the value you provide. They don’t need to be fancy—just clear, well-lit photos taken on the job with a quick caption like: “Another A/C install wrapped up in Scottsdale. From no cool air to total comfort—same day.”
These posts prove you’re experienced, reliable, and active in the local area. Bonus points if you tag the neighborhood, include your branded truck in the background, or add a customer quote alongside the photos.
Post Type #3 – Customer Testimonials and Reviews
Five-star reviews don’t just look good on Google—they’re gold on social media, too. Turning those reviews into engaging posts helps build trust and shows potential customers that real people are happy with your work.
You don’t need anything fancy. A simple quote graphic with a reviewer’s first name and location—paired with a photo of your team or the completed job—adds a personal touch that makes people stop scrolling.
Try captions like: “Thanks to Sarah in Des Moines for the kind words! We were happy to get her heat back on the same day.”
Even better? Use video. A short clip of a homeowner giving a quick testimonial—or your tech reading a recent review on camera—can feel authentic and relatable.
Pro Tip: Include hashtags like #HappyHomeowners or #[YourCity]HVAC to expand your reach locally.
Post Type #4 – Meet the Team and Behind-the-Scenes Moments
People don’t hire companies—they hire people. Social media gives HVAC companies a chance to show the human side of the business, and that’s exactly what builds loyalty and long-term trust.
Introduce your techs, share office birthdays, post fun moments from training days or lunch breaks. These small glimpses behind the curtain remind your audience that you’re not just a brand—you’re their neighbors, too.
A quick post like “Shoutout to Carlos for crushing three A/C installs today in Sandy Ridge!” puts a face to the service and makes your brand more memorable.
Pro Tip: Video works great here. A short reel of a tech prepping for a job or offering a quick maintenance tip can boost engagement and trust in one scroll.
Post Type #5 – Service Promos and Financing Offers
Let’s face it—sometimes, people need a little push to book that tune-up or replace their aging system. That’s where social media promos come in.
Use your platforms to share limited-time deals, seasonal maintenance specials, or financing options. Posts like “$89 A/C Tune-Up—This Week Only!” or “0% Financing Available on New Installs” create urgency and drive conversions.
Keep your message clear and your call-to-action front and center: “Call now,” “Book online,” or “Send us a message to claim.”
Add a bold image, clean design, and maybe a countdown graphic to create a sense of urgency without sounding salesy.
Pro Tip: Promote the same offer across Facebook, Instagram, and even your Google Business Profile for maximum reach.
Post Type #6 – User-Generated Content and Community Involvement
HVAC companies thrive on local trust—and nothing builds that faster than showing you’re part of the community.
Repost customer shoutouts, tag clients (with permission), or share photos of your team at local events. Sponsoring a youth baseball team? Snag a photo of the jersey and post it with pride. Hosting a canned food drive? Show your crew packing the donations.
These posts don’t just build engagement—they build emotional connection. People want to support businesses that give back and feel familiar.
Pro Tip: Use local hashtags like #[YourCity]Community or #[YourTown]Strong to expand your reach and encourage neighbors to share your posts.
Post Type #7 – Answering Common Questions
Every HVAC company hears the same handful of questions over and over. Use that to your advantage by turning FAQs into quick, informative social posts.
Think simple, scroll-stopping content like:
- “Why does my A/C smell musty?”
- “How often should I really replace my filter?”
- “What size system do I need for a 2,000 sq ft home?”
You can answer with short captions, video clips, or carousel graphics—whatever matches your audience’s attention span. The goal is to educate while keeping it conversational.
Pro Tip: Save your best-performing FAQ posts and repurpose them into blog content, reels, or even paid ad copy later.
Wrap Up: HVAC Social Media That Builds Trust and Books Jobs
Social media doesn’t have to be complicated—or cringey—to work. For HVAC companies, it’s all about consistency, connection, and content that answers real questions or solves real problems. From seasonal tips to behind-the-scenes moments and customer reviews, the right posts can turn quiet followers into loyal customers.
The key is staying active, authentic, and helpful.
