Every heating and cooling company knows the pattern. The first cold night of fall and the first hot week of summer, the phone rings off the hook, and every caller wishes they had called a month ago.

You can't stop the rush, but you can get in front of it. A few well-timed Facebook posts remind people to book early, and they put your name in front of folks before their furnace quits on a Saturday night.

Before the first cold snap

Start a few weeks before your area usually sees its first freeze. You know your county's weather better than anyone. Here is what to post, roughly in order:

The tune-up reminder. "Furnace season is coming. Book your tune-up now, before the first cold night, and skip the wait." Simple and direct.
The safety post. The CDC says to have your heating system, water heater and any other gas, oil or coal burning appliances serviced by a qualified technician every year, and to put battery-operated or battery back-up carbon monoxide detectors near every sleeping area. (CDC, Carbon Monoxide Poisoning Basics) Quote it, link to it, and add your number.
The filter post. A photo of a dirty filter next to a clean one. Everybody understands that picture.
The "what's that smell" post. A short note that a little dusty smell the first time the heat comes on can be normal, but a gas smell is a different matter, with a link to your gas utility's safety page. Keep it calm and clear.
The thermostat tip. How to switch from cool to heat, and to check the batteries. It sounds basic. People still call about it.

Before the first heat wave

Do the same thing in spring, a few weeks before the first hot spell.

The AC check reminder. "The first hot week is coming. Get your AC checked now so it's ready when you need it."
Clear the outdoor unit. A photo of a condenser buried in cottonwood fluff or grass clippings, and one cleaned off.
Change the filter. Yes, again. It's the post that never goes out of style.
What to do if the house won't cool. Check the thermostat setting, check the breaker, check the filter. If it's still warm, call. Giving people a few easy checks shows you're not just after the service call.
Look after the older neighbors. A reminder to check on elderly relatives and neighbors during a heat wave is a kind thing to post, and people share it.

Make every post easy to act on

A post that helps but doesn't say who you are is a public service. That's fine sometimes, but most of the time you want people to know who to call. End posts the same way every time:

Your business name.
Your phone number, written out.
One line about how to book: call, text or a link.

Keep the wording plain. "Call us at 555-0123 to book a tune-up" works better than a clever slogan. Use a real photo from your own trucks or crew when you can. A picture of your actual van in a local driveway says more than stock photos ever will.

A simple calendar you can copy

If you want to keep it simple, here is a pattern to follow each year:

Late summer: one post a week about booking fall tune-ups.
Three weeks before the usual first freeze: two or three posts a week, mixing tips with reminders.
The week of the first cold snap: one post with your number, your hours and what to do while they wait.
Late winter: one post a week about spring AC checks.
Three weeks before the usual first hot spell: two or three posts a week, tips and reminders.
The first heat wave: one post with your number, your hours and a few things to check first.

Write the posts in a slow week and schedule them ahead. Facebook lets you pick the date and time.

Where a song fits

Tips get read once. A song with your name and number in it is something people can play again, hum, and pass along to a neighbor. Our Jingle package is a 30-second song written new for your company, with your name, what you do and your phone number, plus a vertical video with captions for Facebook, Instagram and TikTok and the song as an MP3 you can use on hold or on the radio. It's $750, paid once, and you don't pay until you've seen the result.

A good time to have it ready is right before the season starts, so you can post it alongside your reminders. If you'd rather talk first, ask us to call you.
