HVAC is a highly seasonal trade, and the seasons are the whole marketing problem. Demand spikes twice a year: when the first real heat arrives, and when the first real cold does. In between, the market goes quiet while the overheads do not.
Many HVAC companies respond by advertising hard during the spikes. That is when every rival is bidding, so it is also when clicks cost the most. The contractors who do well spend differently. They buy the trough, the quiet months, and harvest the spike.
The three revenue lines, and how each is won
Emergency service
No heat, no cooling, a unit that dies in a heatwave. Urgent, by phone, and decided in the map pack: the map results Google usually shows near the top of the page. It is won on how close you are, your reviews, your open hours and whether you pick up, the same way plumbing emergencies are.
Replacement
HVAC replacement is the high value line: a system at the end of its life, often a five figure job. Homeowners research it for weeks and get several quotes. Financing is usually part of the choice. This is where the website matters most, and where content published in the quiet months does the work.
Maintenance agreements
The line that changes the business. A maintenance plan turns a one time customer into steady, repeat revenue. It gives the technician a reason to be in the house before the unit fails. And it turns the next replacement into a warm sale, not a bidding war.
Marketing that only chases emergency calls buys the cheapest kind of revenue at the highest price.
Buying the trough
The plan that works in HVAC runs against the seasons. It is unpopular, because it asks you to spend when the phone is quiet.
Publish before the season, not during it
The content that ranks for air conditioner replacement in July was published in March. Pages take weeks to earn their place. Publish during the spike and you arrive after it.
Run maintenance offers in the shoulder months
Spring and fall are when a tune up is an easy yes. Every plan sold is a replacement quote later.
Keep the profile warm year round
Reviews, photos and posts through the quiet months hold the map pack spot that the spike will pay for.
Let paid carry the peak
Paid ads should carry the HVAC peak season, because when everyone is bidding, paid is one of the few channels that scale at once. Organic coverage is what stops you having to bid on everything.
What the pages have to do
A page per service and per system type
Furnace repair, AC replacement, heat pump installation, ductless mini split, duct cleaning, indoor air quality. One combined services page rarely ranks for any of them.
Price ranges and what moves them
An HVAC page that explains price ranges, what drives the number and what financing exists gets shortlisted by people who would otherwise never call. A replacement is often a five figure choice.
Efficiency and rebates, explained
SEER ratings (how efficient a unit is), local utility rebates and tax credits all shape the choice. Homeowners research them. Many contractors barely mention them.
Brands carried and certifications held
These are search terms as well as signs of trust.
Suburb pages only where there is real material
How old the homes are, typical system types, climate load, permit rules. No local material, no page.
What Kihan Marketing can show you
Kihan Marketing can show you roofing results, the closest published work it has to HVAC. It has no HVAC case study, and will not imply one.
One client is a roofer in Greater Austin. The work started as roofing SEO for a single location. The site grew from roughly 50 pages to more than 250. More than 40 of them now cover towns and neighborhoods in Central Texas. From July to September 2026, organic clicks in Google Search Console more than doubled against the same days in 2025, from 1,076 to 2,203.
These are roofing results, not HVAC results. But roofing shares HVAC's shape. Demand follows the weather. The market is a driving radius. Big replacements sit next to urgent repairs. And proof of finished work is the thing rivals cannot copy.
What to expect
Profile work moves fastest. Service pages move impressions within a month or two, and rankings in around sixty to ninety days. That is exactly why the publishing plan has to run ahead of the season, not with it.
Ad spend goes straight to the ad platform, not through us.
Questions HVAC contractors ask
What is HVAC marketing?
HVAC marketing is the work that gets heating and cooling contractors found by homeowners, in the busy months and the quiet ones. It covers the map pack for emergency calls, pages for replacements, and offers that sell maintenance plans. Marketing for HVAC companies should spend in the quiet months, so the busy season costs less.
What is HVAC SEO?
HVAC SEO is the part of HVAC marketing that wins Google's free results and the map pack. It means a page for each service and system type. It means pages on price ranges, rebates and efficiency, and suburb pages where there is real local material. It also means a Google Business Profile kept active all year.
How much should an HVAC company spend on marketing?
An HVAC company should set its marketing spend by season, market and goal, not by a fixed rule. Spending only in the spikes means paying the highest click prices. Moving some spend into the quiet months, for content and maintenance offers, eases what the peak costs. Pricing explains what moves the size of our own work.
How much does Google Ads cost per lead for HVAC?
The cost per lead from Google Ads for HVAC depends on the season, the market and what happens after the click. Clicks cost the most in the spikes, when every rival bids. A landing page that matches the search, tracked calls and negative keywords all help keep the cost down. Ad spend goes straight to the ad platform.
Is local SEO worth it for HVAC companies?
Local SEO is worth it for HVAC companies because emergency heating and cooling calls are decided in the map pack. A homeowner with no heat calls one of the first few map results. Reviews, photos and posts kept up through the quiet months hold that map spot, so it is there when the next spike comes.
