For heating, cooling and HVAC companies
HVAC websites that handle the heatwave and fill the quiet months.
A heating and cooling website that answers every "my AC just stopped" at once, sells maintenance plans to your customers, and reminds them before each season. Then it asks for the review.
- Maintenance plans customers buy on your site
- Seasonal tune-up reminders by email
- Chat that answers and books on the busiest day
- A page for every service and every town

Where the work goes
Five ways a heating and cooling business loses work it should have had.
Your year has two rushes and two lulls. Most lost jobs happen in the rush, and most lost customers in the lull.
The first hot day of summer, and every phone line is busy.
The chat on your site answers everyone at once from your own pages: the areas you cover, how soon you can come, what a diagnostic visit involves. It books into your real free slots, so nobody waits on hold to be told there is no slot.
Chat and bookingsNo heat at nine on a January night.
The Voice Agent answers your business number from what your site says, books the first free visit or takes a callback, and saves the caller as a contact with a summary. It is a per-site add-on, on the number you already have.

Sell a maintenance plan on your site as a pack of visits or a yearly membership. Before each season, send a tune-up email to everyone with a plan, or to every customer you serviced last year. Follow-ups are saved switched off until you read them, and texts go only to people who opted in, with the SMS add-on.
Maintenance plans and email"Repair or replace?" cannot be answered from a phone call.
Your quote form asks what you need: the system type, its age, the problem, the size of the home. They attach photos of the unit and its rating plate from their phone, and the pictures arrive with the enquiry.
Quote formsA stranger is about to work on their gas furnace.
Your licence, insurance and certifications, such as EPA or Gas Safe registration, sit on every page next to your Google reviews. Link your Google Business Profile and get it verified from Mondovo, so the listing and the site agree.

What is on your HVAC site
What a good HVAC website has. Yours starts with all of it.
Drafted from a few sentences about the business. You read the plan for every page before anything is designed, and change what is wrong.
Use your own photographs of the work. A generated picture of an install you never did is a promise you will have to explain in the plant room.
- A number you can tap to call, at the top of every page
- Emergency hours for no heat and no cooling, said plainly
- A page for each service: AC repair, furnace and boiler repair, installs, heat pumps, tune-ups
- A page for each town or area you cover
- Maintenance plans, with what each visit covers
- Online booking for repairs, tune-ups and estimates
- A quote form that takes photos of the unit
- Your licence, insurance and certifications
- The brands you install and service
- Reviews from your customers
- A chat that answers when every line is busy
- Questions people ask: repair or replace, how often to service, what to check before calling
One firm, three looks
The same heating and cooling firm, described once, in three designs.
Each round gives you three complete versions from one content plan. Same pages and words; only the look changes. A site can hold up to ten, and you choose which one is live.

Cream and terracotta, a photo grid of the services.

Soft cream, a repair-or-replace guide up front.

Deep navy, the service area in the headline.
Real generated sites, shown as demonstrations rather than customers. The firm and everything written on it are invented.

What it does not do.
It does not size systems or arrange finance
No load calculation, estimating or finance applications. Quote requests arrive with the details and photos you ask for; the recommendation and the price stay with you.
It does not dispatch your technicians
Customers book the visits themselves, plan visits included. Routing vans, managing parts and sending invoices stay where they are now.
It answers calls, it does not make them
The Voice Agent answers incoming calls and takes callbacks. It does not ring customers or transfer a live call.
What it costs
Build free. Go live with Pro.
Pro is one price per live site, per month, shown in your currency on the pricing page.
- Building, designs and previews
- Free
- Going live, hosting, SSL

- Bookings, plans, chat, forms, inbox
- Included
- Pages, visitors, enquiries
- Not counted
- Voice Agent, text messages
- Per-site add-ons

- Credits
Editing the site, by hand, by chat or by voice, never uses credits. Your phone provider bills you directly for the number and call minutes, and your payment provider charges its usual fees on plan sales.
See pricing for your countryQuestions
Asked in the quiet season.
I do not have time to build a website.
Write a few sentences about the business: heating, cooling or both, the towns you serve, the brands you fit. A complete site is drafted from that, and you check a plan of every page before anything is designed.
Can I sell maintenance plans on the site?
Yes. Set up a plan as a pack of visits, such as a spring AC tune-up and an autumn furnace or boiler service, or as a yearly membership. Customers buy it on your site and use it when they book a visit. Memberships renew through your own Stripe account.
What happens on the first heatwave, when everyone calls at once?
The chat on your site answers at the same time for everyone, from your own pages, and books into your real free slots. With the Voice Agent add-on, calls to your business number are answered too, with a callback taken when the diary is full. Every request lands in one inbox.
Can it answer my phone out of hours?
Yes, with the Voice Agent add-on. Point your Twilio, Plivo or Exotel number at your site and it answers from what your site says, books a visit or takes a callback, and saves the caller. Try it in your browser before you connect a number.
Will people find me?
Every page has its own title and description, publishing adds a sitemap and structured data, and a page for each service and town gives search something to match. Rankings depend on many things and are not guaranteed.
I already have a site.
Give it the address. The pages and words are brought across, and the design is rebuilt around them. You see what was found before anything is generated.
Your business
Say what you heat, what you cool and where.
Building and trying designs is free, and nothing is public until you say so.
