Sample designs
Looks like a $5,000 agency website. Judge for yourself.
Six Zarla designs, shown for made-up HVAC companies, from same-day AC repair to commercial rooftop units. Start from one and the AI rewrites it around yours, or let your brief decide.
Heating
Hearth & Coil Heating
A technician at work, a warm palette and a 24/7 no-heat line, for the company customers call when the house goes cold.
Maintenance plans
ComfortClub HVAC
Sells the membership, not the repair: two tune-ups a year, priority service and money off, with a sign-up form on the page.
Heat pumps
DualStage Heat & Cool
Lower energy bills and rebates in the headline area, for the installer selling the switch to heat pumps.
Commercial
Ironclad Mechanical
Rooftop units, refrigeration and maintenance contracts, written for the people who run buildings.
Family-owned
Bramwell & Sons HVAC
"Three generations of comfort" and "since 1984", for the family firm that wins on trust.
The checklist
What every HVAC website needs
Six things an HVAC website needs to fill the schedule, each shown on one of Zarla's designs.
- 01
A quote form in the first screen
Name, phone and what's going on, right under the headline. At 110 degrees nobody wants to wait on hold; the form starts the job.
- 02
A number and an emergency button up top
A dead AC in July is an emergency. The number and an emergency button belong in the header on every page.
- 03
A maintenance plan customers can join
Members call you first and book the tune-ups that fill slow months. Put what the plan includes where customers can see it.
- 04
Financing, said up front
A new system is a big bill. Saying you offer financing answers the first question before the customer shops around.
- 05
The job and the town in the headline
"AC Installation in Sacramento, CA" is what the customer typed, and the proof they've found the right company.
- 06
Proof in numbers
Systems installed, years in business, your Google rating. A number reads faster than a paragraph about quality.
Process and turnaround
How it works, and how long each step takes
For comparison, from the price pages of web agencies that build HVAC sites: 2–3 weeks at two subscription companies, "within a couple of weeks" at a web designer for HVAC companies, 30 days to four weeks at two marketing agencies, and 8 to 12 weeks for a semi-custom build at a WordPress development agency.

What's included
What you get from your first brief
- The design. Layout, colors, fonts and photos picked for an HVAC company.
- The words. Headlines, service descriptions and FAQs written from your brief. Edit any of it.
- Service and area pages. Pages for the work you do (AC repair, furnaces, heat pumps, maintenance) and the towns you cover.
- Quote request form. Your customer describes the problem and it lands in your leads inbox, with an email alert. Customers can attach up to five photos of the job to the form, so you can often price it from the photos instead of a site visit. The form doesn't work out a price for you — you read the request and quote it yourself.
- Tap-to-call buttons. On every page, for the customer sweating through a heat wave.
- Google groundwork. Titles, descriptions, business markup and a sitemap on every page, and fast pages on phones.
- Your Google reviews and listing. Connect your Business Profile and your rating, reviews and map show on the site.
- Hosting on Google Cloud, with SSL. Nothing to set up.Premium
- Your own domain. Connect the one you have or buy one inside Zarla.Premium

The honest part
What an agency does that Zarla doesn't
Zarla does the design part of an agency's job with AI. Here's what you'd still be paying people for.
- A strategy call about your market and your competitors
- Original photos of your team, vans and jobs. Zarla uses your photos or stock.
- Copy written from interviewing you. Zarla writes from your brief, and you edit it.
- Monthly SEO campaigns, link building and ranking reports
- Running your Google Ads and Local Services Ads
- One named person accountable, on the phone
- Custom features beyond Zarla's sections

Browse Zarla partners →Questions HVAC businesses ask
Is Zarla a web design agency?
No. Zarla is AI. It does the design part of an agency's job, the layout, words, pages and forms, from a one-sentence brief. There's no designer on the other end. If you want a person for marketing or SEO, Zarla partners are independent agencies and freelancers who work on Zarla sites.
How much does HVAC website design cost?
Web designers who publish prices for HVAC sites charge $0 to $4,499 up front and $150 to $1,999 a month for a managed site. Website-and-marketing packages run $659 to $5,000 a month, some on 12-month agreements. Designing and previewing on Zarla is free; you choose a Premium or Business plan when you publish.
What pages should an HVAC website have?
A home page with your number and a quote form in the first screen, a page for each service (AC repair, installs, heating, maintenance plans), a page for each town you cover, a financing page if you offer it, and your reviews. Zarla adds service and area pages from your brief, up to your plan's page limit, and you add more by typing. Customers can attach up to five photos of the job to the form, so you can often price it from the photos instead of a site visit. The form doesn't work out a price for you — you read the request and quote it yourself.
How long does an HVAC website take?
Agencies that publish timelines quote from a couple of weeks to about four weeks for a managed HVAC site, and 8 to 12 weeks for a semi-custom build. Zarla's first design takes about 30 seconds; after your changes, you can publish the same day on a paid plan.
Can customers book a service call online?
Yes. Zarla's online booking lets customers pick a time on your website; bookings sync to Google Calendar, and you can take a deposit through your own Stripe account.
Does Zarla do HVAC marketing?
Zarla does the groundwork Google reads: titles, descriptions, business markup, a sitemap and fast pages on phones. It doesn't run ads, Local Services Ads or monthly SEO; that's agency work. Our guide to HVAC marketing covers the rest.
I already have an HVAC website. Can I move it?
Yes. Zarla keeps your old page addresses where it can and redirects the ones that change, helping you keep the Google standing you've built.
