If you hate money, then don’t do email marketing. The average ROI for email is about 36x. That means for every $1 you spend on software or doing email marketing, you can get $36 back.
Email marketing is a type of content marketing where email is how you get your message to your market. A solid email marketing strategy helps you stay connected with customers before they need emergency service.
Because of that, it’s not that different from any other advertising channel you use to tell people about your stuff. And, unlike social media, you control who gets to see it instead of some algorithm.
With every email you send, your objective should be to either increase the likelihood that someone purchases in the future or get them to buy now.
Email Campaign Examples for HVAC Businesses
Use these examples to know what to write and when to send them. Each campaign example includes a complete template (subject lines, body text, and a sales pitch as a call to action) you can copy and tweak.
Important: Replace anything in brackets with details specific to your situation.
Seasonal Readiness Campaign
People naturally procrastinate on maintenance until something breaks. Which always happens at the worst possible time and ends up costing more money.
Connect the upcoming season to the benefits of doing something before things get busy. Send the first email in this sequence 6–8 weeks before peak season, with emails spaced weekly and the final email going out 2–5 days before your busy season starts.
Email #1: Season Change Reminder
Alert customers when a specific season is approaching and explain the consequences of waiting to do something until their system fails during peak demand.
Subject: Summer is just x weeks away (your AC ready?)
Your air conditioner is about to face its biggest test of the year.
Last summer, we had customers paying $400+ for emergency service that would’ve cost $150 if they’d scheduled a checkup right now.
Others had to go days without AC because every company in the city was booked solid.
Your AC doesn’t care that it’s inconvenient to break down during your daughter’s graduation party or when you’re hosting out-of-town guests. It’s going to quit when it’s pushed hardest. When you need it most.
The good news?
Most breakdowns are preventable with a simple tune-up before the heat hits.
Schedule your Beat the Heat Checkup now before the rush. Same-day service available through May 20th.

PS - How it feels when your air goes out in the summerQuick Note About PS Statements
PS statements are one of the most read parts of an email besides the subject line.
You want people to click the link for your main offer. But if they don’t, we still want to get people used to clicking links in the emails we send.
It helps condition behavior and sends positive trust signals (in the form of click-through rates) back to your email provider, which makes it easier for your emails to land in their inbox and not the promotions tab.
In these examples, the PS statements link to memes to make people laugh. If you can’t get them to click on your main offer, you at least want them to remember you (we call this aided and unaided recall in the marketing world). Making people laugh works pretty well for that.
I encourage you to do what you feel comfortable with, though. Experiment and try things out to see what works best for you.

PS - What it’s like when your AC goes out during a heatwaveReview Generation Campaign
This is what we call an evergreen campaign, meaning you can run it all year long to keep a steady stream of new reviews rolling in.
Email #1: Asking for an Honest Review
In the first email, you offer something in exchange for the customer leaving you an honest review. Phrase it as compensation for their time while emphasizing how their feedback helps other homeowners.
People are busy, and leaving you a review is usually not at the top of their priorities. Offering compensation helps, but a deadline gives people that extra motivation to overcome procrastination.
Important Compliance Note
Platforms like Google explicitly prohibit compensating people in exchange for reviews.
But that doesn’t stop some business owners from doing it to help them rank higher on Google anyway.
Make sure you’re aware of the rules (and risks) of the platform you’re trying to get reviews on beforehand.
The Federal Trade Commission does not prohibit compensating people for reviews as long as you’re not compensating them on the condition that they leave you a positive review.
When asking people to leave a review or feedback, ask them to share their honest experience.
For more guidance, see the FTC’s Guide to Paying for Online Reviews.
Subject: Get ${25} for 2 minutes of your time
Leave us a review sharing your honest experience with our service before {date} and we’ll send you a ${amount} gift card.
Your review helps others just like you know who to hire when they need help.

1. Click this link and leave an honest review on {platform}.
2. Reply to this email with a screenshot before {deadline}.
3. Get your ${amount} Amazon gift card within {48} hours.

Other Campaign Ideas
Don’t limit yourself to the examples above. Here are some additional campaign ideas you can try out. There’s no need to try them all at once. Pick the ones that match your business and customer base the best.
TIP: If you’re not sure what to write and don’t feel like learning all the ins and outs of being a copywriter, you can always contact us for help.
New Homeowner Welcome Series
New homeowners don’t know what they don’t know. Help them out.
TIP: Partner with local real estate agents or brokers to educate new homeowners on the basics of HVAC maintenance.
Email #1: Welcome to Homeownership. Congratulate them and introduce the hidden HVAC costs/issues that most new homeowners don't discover until it's too late. You can offer them a new homeowner’s discount in the very first email, too.
Email #2: First Month HVAC Priorities. Give them a checklist of things to look for in their first 30 days.
Email #3: Avoid the $5,000 Surprise. Share common expensive HVAC problems that catch new homeowners off-guard and how to prevent them.
Email #4: The Myths. Address all the things your potential customers tell themselves that are stopping them from taking your initial offer. What are the things they tell themselves that keep them from moving forward or taking action? It’s almost always something related to time, effort, cost, or perceived risk (or lack of).
Email #5: New Homeowner Discount. Offer the special new homeowner maintenance package or inspection discount again. Reinforce urgency by emphasizing when the offer ends and what it could cost them later.
Filter Replacement Reminders
Most homeowners forget to change their filters until their system starts acting up. Use your CRM to set up automated reminders based on their last service date to keep them on track.
One of the trickiest things with email marketing is having something to say that your customers will actually find relevant and useful. 59% of Americans say that most emails they receive are not useful to them (Edison Mail, 2023).
Reminding people it’s time to change their filter gives you a good reason to reach out and make one more good impression with your customers in a valuable way.
TIP: You can also use your CRM to determine the size and type of filters they need, and give them links to purchase filters directly from you or from an online retailer where you can earn affiliate commissions.
Heat Pump Upgrade Series
Upsell existing customers with old furnaces/AC units to modern heat pumps by demonstrating energy savings, rebates, and year-round efficiency benefits.
Getting people to take action when what they already have is still working is the hardest part. Try explaining how repairing furnaces is only going to get more expensive because fewer and fewer HVAC contractors know how to even diagnose and fix them anymore.
If you have numbers on how many of their neighbors (or people in their city/county) have already made the switch, you can mention that too. The Bandwagon Effect and Fear of Missing Out can be powerful motivators to get people to take action.
System Replacement Timing Series
Educate customers with 10+ year old systems about when to repair vs. replace. Position it as “Planned Replacement vs Emergency Replacement.” Send these during shoulder seasons (especially in spring before people get their tax returns).
Highlight manufacturer rebates (and if they’re expiring soon) and how it’s cheaper to do this now than during the middle of summer or winter.
Anticipate and address the objections they’re going to have. Use any and all social proof you have in the form of reviews, stories from past customers (including those who waited too long and paid the price for it).
Referral Generation Campaign
Happy customers are your best source of new business. Create a simple referral program that rewards existing customers for sending friends and family your way. Offer incentives like account credits or gift cards when their referrals book a service.
Tactical Email Marketing Tips Worth Mentioning
There are a few things to keep in mind to avoid some common mistakes before you go running email campaigns using the examples above.
Make Unsubscribing Easy
People unsubscribing from your emails isn’t necessarily a bad thing. Email is just another way to tell people about your stuff. If people unsubscribe, it doesn’t necessarily mean they don’t want to buy or that they don’t like your company. It may just mean they don’t prefer that form of communication.
You don’t want to keep sending emails to a list of people who aren’t interested. Doing so will just make it harder to reach the primary inbox of everyone else.
So make it easy for people to unsubscribe.
- Include your company name and address in every email. Adding your phone number is a good practice too. Especially for local service businesses.
- Place visible unsubscribe links within your emails.
- Use real email addresses in the "From" and "Reply to" fields.
- Write subject lines that indicate the contents of the email.
Additionally, this is not legal advice. Review the FTC's website for more specific legal information regarding laws related to the CAN-SPAM Act.
We have a ton of experience with this and know how to remain compliant. If you’re worried you’ll make a mistake or just need help, please reach out to us.
Segment Your List So You Send the Right Emails to the Right People
Segmentation, in this context, means dividing your email list into smaller groups based on what those people have in common. Instead of sending the same email to everyone, you send specific messages to specific groups of people.
Think about it like this: a customer with a brand-new HVAC system isn’t going to be interested in getting a series of emails about replacing their older units.
Or a homeowner dealing with their first emergency isn’t going to care about the same things a property manager responsible for the upkeep of multiple apartment complexes would.
Examples of Ways to Segment Your List
Start with simple characteristics you (hopefully) already track about your customers.
- System Age: New, Mid-lift, Aging
- System Type: Ductless, Central, Geothermal, etc.
- Customer Type: Residential vs Commercial
- Service History: New customers, regular maintenance customers, customers who’ve only ever hired you for emergencies.
- Location: Create 3-4 groups based on how far or how long it takes to get to them.
- Property Type: Single-family homes, condos, apartments, office buildings, etc.
- Marital Status: Single vs Married
- Pets: Have pets vs no pets.
If you have a marketing suite capable of advanced tracking, you can start segmenting people based on their behavior.
For example, you can measure how engaged they are by measuring how they interact with your emails, your website, or any paid ads you’re running.
People don’t often delete their personal email accounts, but if they do, you’ll see it in your bounce rate metric. Keep an eye on it and remove people if their email address bounces.
Keep Your Emails Simple and Text-Based
You want your emails to look like emails. You’re not an ecommerce company. Save the fancy graphics and layouts for social media. The more images and links you add, the higher the likelihood your emails will end up in the Promo tab.
Simple, text-based emails work. They have a better deliverability rate and are easier for customers to quickly scan and understand.
Also, don’t forget to check how your emails look on mobile before sending them. Most email marketing platforms have features for this. For example, HubSpot and Mailchimp both let you see what any email will look like across a variety of devices and email clients.
Save the Advanced Stuff for Later
Focus on the basics if you’re just getting started. Don’t get overwhelmed trying to do every advanced strategy or tactic you read about online.
A/B Split Testing
Testing different subject lines and email content can improve results. But I wouldn’t worry about this until you have a big enough email list to reach statistical significance.
The exact list size needed for a proper a/b test will vary based on the changes you’re testing, your desired confidence level, the metric you’re measuring, and how long you want it to run.
You’re probably not trying to be a statistician on the side. So start by just getting in the habit of consistently sending emails and listening to customer feedback before you worry about optimizing everything.
Advanced Segmentation
Don’t try to create a bunch of different customer segments based on complex criteria.
Worry about getting a proper CRM setup and training your staff to use it first.
Some segmentation is fine in the beginning. Just keep it simple. For example:
- Leads vs Existing Customers
- Residential vs Commercial
That’s a good place to start. Add more as your email list grows and you understand your market more.
Marketing Automation Workflows
Some marketing automation tools will help. But complex drip sequences with multiple decision trees and variable-based conditional logic can wait.
But if you’re the type of person who just wants to get things right the first time, hire an agency with experience marketing HVAC companies to do it for you. That way, you can focus on what you do best—running your business and serving your customers.
Start simple, stay consistent, and scale up when you're ready.
Still Not Sure Where to Start?
Your customers just want to be comfortable. Help them get what they want by giving them useful information that’s relevant, simple to understand, and easy to act on.
Start with one campaign. Pick the seasonal readiness series if you’re approaching summer or winter. Or try to review generation if you want to see a quick boost in your local rankings on Google.
Send simple, text-based emails. Your biggest competitive advantage won’t be fancy email templates. It’s being the company that people remember before they have problems, not just after.
Still not sure where to start? Look, I get it. You’re busy running your business. Writing copy, creating email templates, segmenting your lists, building automation workflows, configuring DNS settings, and tracking all the data that goes along with it isn’t exactly what you dreamed of doing with your week.
