One HVAC marketing agency for your ads, website, follow-up and tune-up reminders. One team, one flat monthly fee, no contract.





The first hot week of summer, every phone in town rings. Systems that sat quiet all spring quit on the same afternoon. Your techs are booked solid and calls still stack up. Then autumn comes, the calls slow down, and you are paying techs to wait for work.
Winter brings the same rush for heating. A family with no heat at 9pm does not wait for a callback. They ring the next company on the list.
Yet most HVAC marketing is set up as if every month were the same. The same ads run all year, on the same budget, with the same message. So you pay top prices for clicks in the weeks you cannot take more work, and go quiet in the weeks you need it most.
That is only half the leak. The other half happens after a lead comes in:
More ad spend does not fix any of that. What fixes it is a plan that moves with the seasons, a fast reply to every call and message, and follow-up that keeps going after the first visit. That is what we run as your HVAC marketing agency, for one flat fee each month.
Google Ads for AC repair in summer and furnace repair in winter, then tune-ups and system replacements in spring and autumn. Local Services Ads can sit on top of that, and we help you get set up. Every ad is refreshed before each season and checked every week. You pay Google or Meta directly.
Learn moreA call button at the top of every page. A page for each service, like AC repair, furnace repair and heat pumps, and one for each town you cover. Plus a replacement page that answers what people ask before they buy a new system.
Learn moreEmails and texts before each season that remind maintenance customers to book their tune-up, and remind them again before their agreement runs out. Plus offers for past repair customers who never joined a plan.
Learn moreThe CRM is included. Missed call text back, follow-up on replacement quotes and review requests after each visit all run on their own. If you already dispatch from field service software, keep it. The CRM handles the marketing side.
Learn moreAn AI chat on your website and by text. It answers common questions, books tune-ups and service calls, and passes no-heat or no-cool jobs to you straight away. It does not answer phone calls.
Learn moreWe tidy your Google Business Profile, write pages that answer real questions like "repair or replace?", and keep reviews coming in. That helps you show up when someone nearby searches, and when they ask ChatGPT who to call.
Learn moreWe work on one request at a time, and each takes about 48 hours. A full website or a new funnel arrives in pieces every few days until it is done.

An HVAC marketing agency gets your phone ringing with the jobs you want, in the areas you want, at the times you have room for them. A good one also makes sure those calls get answered, quoted, followed up and turned into repeat customers.
Many HVAC marketing firms only do one slice. One runs your Google Ads. Another built your website years ago. A lead seller sends you names. Nobody owns the whole path from search to signed job, so nobody can tell you where the money went.
Havstock runs it as one system: ads, website, CRM, follow-up, reminders, SEO and reporting, handled by one small team. You send requests, and each one is done in about 48 hours. You pay one flat fee each month.
HVAC marketing should change with the calendar, because your customers do. Summer and winter are about speed and repairs. Spring and autumn are about tune-ups, agreements and planned replacements.
When the heat arrives, people search for AC repair and call whoever answers. Your ads should lead with AC repair and same-day service, if you offer it. Your site should make calling you the easiest thing on the page. If the schedule is full, we can pull ad spend back, so you are not paying for calls you cannot take.
The same thing happens with furnaces and heat pumps on the first cold nights. We swap the ads, landing pages and chat answers over to heating. No-heat calls are urgent, so the same speed rules apply.
These are the slow weeks, and the best time to sell planned work. Tune-up reminders go to maintenance customers. Offers go to past customers. Ads shift to system replacements, heat pumps and indoor air quality. This is how you keep techs busy between the rushes.
We plan this calendar with you on the first strategy call. Then we change ads, pages and emails before each season begins, not once it is under way. More on how we run Google and Meta ads.
A repair call and a new system are bought in different ways, so your HVAC advertising should treat them differently. Repairs are won on speed. Replacements are won on trust and follow-up.
come from people whose system is broken right now. They search, pick a company that looks trustworthy, and book whoever answers first. What wins: showing up at the top of Google, a phone number they can tap straight from the search results, and a fast reply.
are big decisions. The homeowner gets a few quotes, reads reviews, asks about running costs and warranties, and often asks how to pay for it. What wins: a clear replacement page, real reviews, a quick quote, and follow-up that does not stop after one email.
Financing questions come up often on replacements. If you offer financing through a lender, we can build a page and an email that explain it in plain words and link to their application. The rates and terms come from your lender, and you approve every word before it goes live.
Many replacements start as repair calls. A tech finds an old system that is on its way out. That customer should get a replacement quote, then a few follow-ups by email and text over the next weeks. We set that up in the CRM so it runs without anyone having to remember.
Maintenance customers have already picked you once. Marketing to them is mostly about reminding them at the right time, so they book, renew and stay.
That means a reminder before each season to book a tune-up, sent by email and text to customers who agreed to hear from you. A second reminder before the agreement renews. A thank-you and a review request after each visit. And an offer for customers who had a repair but never joined a plan.
In many shops, these reminders depend on someone in the office remembering to send them. In a busy week, they do not go out. We build them into the CRM so they send on their own, and you can see who booked, who renewed and who did not. Here is more on email marketing and follow-up in the plan.
HVAC lead generation comes from two places: channels you rent and assets you own. Renting is quick to start but stops when you stop paying. Owning takes longer but keeps working.
lead sellers, Google Ads, Local Services Ads and Meta ads. You pay for each lead or click. Lead sellers are the hardest to judge. Many lead sites send the same lead to several companies, so you are racing other shops to call first. If you buy leads, read the contract, ask who else gets each lead, and track every one to a booked job.
your website, your Google Business Profile, your reviews and your customer list. Nobody can switch them off. Every finished job adds a review and a name to your list, which makes the next job easier to win.
So how do HVAC companies get leads that last? Mostly from Google search and Maps, reviews, past customers and referrals. Paid ads fill the gaps and cover the rush. The goal is to lean on rented leads a little less each year, not to quit them overnight.
When a system fails in a heatwave or a freeze, speed decides who gets the job. If your phone rings out, the caller tries the next company within minutes.
Your team cannot answer every call from a crawl space. So we set up the backups:
Anyone whose call you miss gets a text from your number within seconds, so they can reply instead of calling a competitor.
It answers common questions, books routine visits and passes no-heat or no-cool jobs to whoever is on call. It does not take phone calls.
Your ads and your Google profile should match the hours you really answer. If you run Local Services Ads, this matters more now: from 1 October 2026, Google can charge for some missed calls. We explained the Local Services Ads missed call change and what to fix.
If you want a person to pick up every call live, you also need an answering service. Our plumbing answering service guide compares human, AI and mixed options, with prices. It was written for plumbers, but the same choices apply to HVAC. Our page for plumbing companies covers the rest of that trade.
You can hire a marketer, pay an agency, or subscribe to Havstock. The right choice depends on how much you want done and how you want to pay for it.
A full salary, plus tools, plus the time to find and train them. One person rarely covers ads, websites, CRM and SEO well. And they cannot stretch when the summer rush hits.
A monthly retainer, often with a setup fee and a long contract. Many cover one piece, like ads or SEO, and leave the rest to you. Ask who owns the website and ad accounts if you leave.
$4,995 USD a month, flat. Ads, website, CRM, reminders, follow-up, SEO and AI chat. No setup fee, no contract, and the price stays the same while you stay subscribed. Ad spend is extra and is paid straight to Google or Meta. See the pricing page for everything included.
We are a good fit if your crews have room for more jobs, you can spend on ads beyond our fee, and you want the ads, site and follow-up handled by one team. We are not a fit if you need video, photo shoots, printed mailers or daily social posts. Book a 15-minute call and we will tell you straight if it makes sense for your shop.
