HVAC companies have a content advantage most trades do not: every one of your customers owns an expensive machine they do not understand, cannot see working, and think about only when it stops.
That is a large standing appetite for explanation. The difficulty is that most HVAC social feeds ignore it in favour of promotions, which is the one thing nobody is looking for.
This is about organic posting. For paid campaigns, see Facebook ads for HVAC, where the logic is different because the audience has not chosen to hear from you.
The filter reminder, endlessly
The most useful recurring post an HVAC company can make is also the most mundane: change your filter.
It works because it is the only maintenance a homeowner can actually perform, it genuinely affects their bills and their equipment, and it is forgettable enough to be worth repeating every couple of months. Vary the angle: what a clogged filter does to a system, how to read the size off the old one, why the expensive ones are not always better.
Nobody will thank you for it. They will remember who told them.
Repair or replace, the question everyone has
The biggest decision your customers face, and the one they most suspect you of being biased about.
Which is exactly why answering it honestly is powerful. Talk about the age thresholds where replacement genuinely becomes sensible, what a compressor failure means economically, when a repair is the right call even though a sale is available. A company that says “at nine years, repair it” has said something no advertisement can buy.
Indoor air quality, the underused subject
Humidity, ventilation, filtration, what actually helps with allergies, whether the products marketed for this do anything.
Homeowners are genuinely interested and the field is full of overclaiming, so plain, sceptical explanation stands out. It is also the topic most likely to reach someone whose system is working fine: which is to say, someone who is not otherwise thinking about you.
Seasonal, with a rhythm
HVAC content has a natural calendar, and the value sits in the weeks before each shift rather than during it:
- Late spring: what to check before the first hot week, why now is when to book a tune-up rather than in July.
- Early autumn: the first-run smell, what to test before a cold night, when to worry.
- Ahead of a hard freeze: heat pump behaviour in extreme cold, what auxiliary heat is, why the system running constantly is not necessarily broken.
- Peak season: realistic expectations about response times, which is honest and pre-empts the complaint.
Write these ahead of time. The post that goes out the morning of the cold snap is worth several published a week later.
Your feed is also a hiring channel
Skilled HVAC technicians are hard to find, and the ones worth having are usually employed. They are not reading job boards; they are seeing what your company looks like from the outside.
Posts showing the work, the vehicles, the training, how you treat people, these recruit quietly and continuously. For many HVAC companies the labour constraint binds harder than the lead constraint, which makes this the most undervalued use of the channel.
Four things not to post
- Constant promotions. A feed of discounts trains people to scroll past you, and the discount is only interesting the week their system fails.
- Stock photography. The smiling technician beside a spotless condenser appears on a thousand HVAC pages and persuades nobody.
- “Beat the heat!” filler. Says nothing, costs the time you could have spent saying something.
- Equipment specifications. SEER ratings and model numbers matter to you and to almost no homeowner.
Frequently asked questions
What should an HVAC company post on social media?
Explanations, mostly. Filter reminders, honest guidance on repair versus replacement, indoor air quality, and seasonal preparation ahead of each shift in weather. Your customers own equipment they do not understand, which is a standing appetite most HVAC feeds ignore in favour of promotions.
How honest should I be about repair versus replacement?
Completely, and it is worth more than any advertisement. It is the decision customers most suspect contractors of being biased about, so a company willing to say “at nine years, repair it” earns trust that cannot be bought.
When should seasonal content go out?
In the weeks before each shift, not during. A tune-up reminder in late spring lands; the same post in July competes with an emergency. Write freeze and heatwave posts ahead of time so they publish on the day rather than after it.
Can social media help with hiring technicians?
Yes, and it is the most undervalued use of the channel for HVAC. Good technicians are usually already employed and not reading job boards, but they do see what your company looks like from outside. For many companies the labour constraint binds harder than the lead constraint.
Where to start
Pick your next filter-change reminder and write it properly: what a blocked filter actually does, how to find the size. It is unglamorous, it is repeatable, and it is the post your customers can act on today.
