HVAC website design
Websites for HVAC companies, rebuilt in 7 days.
Nobody shops for a heating company on a nice day. They search when the house is already too hot or too cold, usually on a phone, usually annoyed.

Measured 2026-08-25. Google’s test finished on 598 of them; the other 21 are counted as unmeasured, not as passes, because a rate is only honest against the sites the test could run on.
MEASURED ON A PHONE
How long a customer waits for an HVAC company site.
The longer the bar, the longer the wait. Each one grows as fast as that page showed its main content, at five times real speed.

NEW // AI ON THE WEBSITE
A customer sends a photo. The site takes a first look.
They take a picture of what is wrong. In a few seconds the site says what the photo shows, what it could be and how urgent it looks, then puts your number in front of them. Any price it shows is the business’s own typical range from its price list, never a figure the AI makes up, and it never promises a fix.

The field
What HVAC companies in Tennessee are actually shipping.
Not an opinion about what bad websites are like. This is every HVAC company site Google Maps listed for Tennessee towns that loaded for my scanner, run through the same eight checks on the same day. The slowest took 64.6 seconds in Google’s lab test on a simulated phone.

Built for the trade, not recolored
A symptom finder that asks what they actually noticed — warm air, a furnace that will not light, a breaker that keeps tripping — and answers with what it usually means and how urgent it is.
Every site I build is held to the same eight checks I ran on these. What changes between trades is the order, the language, and what the page asks first — because an HVAC company’s customer is not in the same situation as a roofer’s.
A working demo
Calder & Sons · Springfield
An invented business, a real site. Open it on your phone — that is where it is judged, and it is the same build a real HVAC company gets with their own name, services, reviews and photographs.

What an HVAC company usually asks.
- How much does an HVAC company website cost?
- $500, fixed, for a 5-page rebuild, with booking, ordering or payments included if it needs them. That is the whole price: one payment, no retainer, no monthly fee and no setup fee, and it does not change after you say yes.
- How long does it take?
- 7 days from the start date we agree. You see a working demo before you pay anything, built with your real name, services and reviews rather than a template.
- Do I own the website?
- Yes. The domain, the source code and the hosting account are all in your name, and they are yours at handover. Nothing is paid to me after that, so there is nothing to hold hostage. Your only ongoing cost is your domain, about $10–$23 a year, paid to the company that holds it.
- Do I have to sit through a call?
- No. There is no call at any point unless you ask for one. The whole process is 7 steps by email, one of which is optional, and your part is about twenty minutes of typing spread over a week.
- What if I do not like it?
- You see the demo first, so you are judging the real thing rather than a mockup. Revisions have no round limit — the boundary is on scope, not on how many times you can ask.
