What HVAC email marketing is
HVAC email marketing means sending a regular email from your shop to people who already know you: past customers, maintenance-plan members, and anyone who asked for a quote. It's not cold email to strangers. It's staying in touch with the people who already paid you once.
A good one is short. One topic, one offer, your phone number up top, and a button to book.
Why it works for heating and air shops
HVAC is a business where people need you once or twice a year, then forget your name. When something breaks, a lot of them search online and call whoever shows up first, even if they liked you last time.
- It brings back customers you already earned. No ad spend, no shared leads.
- It fills slow months. Tune-up reminders in spring and fall keep the techs busy between the rush.
- It sells maintenance plans. A reminder before each season is the easiest time to ask.
- It keeps you top of mind for the big job. When the system finally dies, they call you, not the first ad.
What to send each month
Match the email to the weather and the season. Here's a year that works for most of the country:
- Fall (Sep to Nov): furnace and heat pump tune-ups before the first cold night.
- Winter (Dec to Feb): carbon monoxide safety, warning signs, and cutting the winter bill.
- Spring (Mar to May): filters and air quality, then AC tune-ups before the heat.
- Summer (Jun to Aug): staying cool for less, storm prep, humidity.
- Any time: rebates and financing for a new system, review requests, and a "we miss you" note to customers you haven't seen in a year.

Do it yourself, or done for you?
Doing it yourself
Tools like Mailchimp, Constant Contact and Brevo, plus the email features in Housecall Pro, Jobber and ServiceTitan, make sending easy. The hard part is writing something good every single month. The trouble is it's easy to put off when the phones are ringing, and once it stops, customers stop hearing from you.
Done for you
Someone else writes, designs and schedules it, and you approve. You pay more than software alone, but it actually goes out every month. That's what Pilot Light does: I write it in your voice, you reply OK, it sends from your account.
What HVAC email marketing costs
- Software only: free plans exist for small lists, and paid plans grow with your list size. You still do the writing.
- Full marketing agencies: email is often bundled into bigger packages, sometimes with a long contract.
- Pilot Light: $249 to $799 a month, with a $199 founding price for the first 5 shops. No contract, first email free. See pricing.
The way to judge it: one tune-up that turns into a repair, or one system replacement from a past customer, usually covers a year.
How to get started this week
- Pull your list. Export customer emails from your field-service software or QuickBooks.
- Pick this month's reason to call. A tune-up special works almost every time.
- Write it short. Under 150 words, one button, your phone number up top.
- Include the legal basics. Your business address and an unsubscribe link in every email.
- Send it, and do it again next month. Consistency is the whole game.
Or skip all five. Ask for your free one and I'll write it for you.
FAQ
How often should an HVAC company email customers?
Once a month is the sweet spot for most shops. Often enough to stay remembered, not so often people tune out.
Is it legal to email my past customers?
Yes, as long as you follow the CAN-SPAM rules: an honest subject line, your business address, and a working unsubscribe link.
What should the subject line say?
Something a neighbor would say. “Before the first cold night” beats “Fall Newsletter, Issue 3.”
Will customers think it's spam?
Not if it comes from your shop, under your name, with something useful in it. Keep it short and local.
What's the difference between this and buying leads?
Leads are strangers, often shared with other shops. Email reaches people who already hired you and already trust you.
