HVAC demand follows the weather, so the slow months between heating and cooling season need a different plan, not just a smaller budget. The companies that stay busy in spring and fall shift their marketing toward maintenance tune-ups and plan sign-ups, replacement estimates, past customers and the SEO work that will pay off when the next heat wave or cold snap hits. They also keep their search ads running for the emergency calls that still happen, just at a lower budget.
Here is how to build that plan.
Why the shoulder months feel so quiet
When the weather is mild, nothing breaks. Repair searches drop sharply, and the companies that rely on emergency calls feel it first. At the same time, competitors who run their ads on autopilot keep bidding, so the few repair clicks left can stay expensive.
The opportunity is that homeowners are still thinking about their systems, just in a different way. They are planning, comparing and fixing things before they become urgent. Marketing in the slow season means meeting them there.
Push maintenance tune-ups and plans
Spring AC tune-ups and fall furnace tune-ups are the natural slow-season offer. They fill the schedule, they get a tech into the house to spot problems, and they feed your maintenance plan.
- Google Ads: run a maintenance campaign with tune-up keywords. Keep it separate from repair so you can budget it on its own. See Google Ads for HVAC companies.
- Facebook and Instagram: tune-up and plan offers work well here, because people do not search for a tune-up until reminded. More in Facebook ads for HVAC.
- Your own customer list: email and text past customers before the season turns. These are the cheapest bookings you will get.
Maintenance plan members are your most valuable customers over time. They call you first when something breaks, and they are the warmest audience for a replacement.
Sell replacements before they become emergencies
A system that limped through last summer is a replacement waiting to happen. In the shoulder months, homeowners have time to compare options, look at financing and get estimates without the pressure of a broken unit.
- Move search budget toward replacement and installation keywords.
- Make sure your replacement landing page sells the estimate, explains the process and shows the brands you install.
- Use your tune-up visits to note aging systems, then follow up.
- Promote any real manufacturer rebates, utility incentives or financing you offer, and only those you actually have.
Talk to the people who already know you
Your past customers are the slow season’s best audience.
- Email and text reminders for tune-ups.
- Follow-ups on estimates that did not close.
- Retargeting ads to people who visited your site.
- Review requests after every tune-up, which also help your Maps ranking.
Do the SEO work now
Slow months are when you have time to build what pays off in peak season. Rankings take months to move, so the pages you publish in spring help you in summer.
- Write or improve one service page at a time.
- Add town pages where you have real work and something to say.
- Fix your Google Business Profile categories, services and photos.
- Build the review habit with your techs.

Adjust budget, but do not switch off
Turning ads off entirely in the slow season has costs. You lose the emergency calls that still happen, your Local Services Ads ranking can slip if you stop taking leads, and restarting takes time to settle.
A better approach:
- Lower the repair budget to match demand.
- Move money into maintenance and replacement.
- Keep Local Services Ads on with the job types you want.
- Watch search terms more closely. Waste shows up more when volume is low.
When the forecast turns, raise repair budgets before the rush, not after.
Use the quiet weeks to fix the account
Slow months are also the best time to clean up your Google Ads account, because mistakes cost less while volume is low. Go through the search terms from last peak season and add the negatives you missed. Check that call tracking still counts the right calls. Rewrite the ads that have been running unchanged for a year. Make sure your repair, replacement and maintenance campaigns each send people to the right page.
Do the same for Local Services Ads: confirm your job types, service area and hours, and mark the outcome of every lead so Google learns which ones booked. When the next rush comes, you want an account that is ready to spend well, not one you are fixing while the phones ring.
Plan your staffing alongside your marketing
Slow-season marketing only works if someone answers the phone and books the work. Use quieter weeks to tighten call handling: how fast calls are answered, how the booking script goes, and whether after-hours calls reach anyone. Better call handling lowers your cost per booked job in every season. See what drives HVAC cost per lead.
A simple slow-season checklist
- Separate maintenance, replacement and repair campaigns.
- Launch a tune-up offer across search, social and your own list.
- Follow up with every open replacement estimate.
- Publish one strong service page.
- Ask every tune-up customer for a review.
- Lower repair budgets to match demand, without turning them off.
- Set a reminder to raise budgets before the next weather swing.
