Short answer: an HVAC company website in the US costs somewhere between about $200 and $20,000 to build, and most established contractors land between $2,500 and $8,000. The spread is not agency margin. It is page count, whether the site talks to your field service software, and whether anyone is writing real content for the towns you actually serve.
Here is what sits in each band and what pushes a quote from one to the next.
The price bands, and what you get
| Band | Typically includes | Sensible for |
|---|---|---|
| $200 - $900 | Template build, 3 to 6 pages, contact form, click-to-call, one service list. Little or no original copy. | New companies, one or two trucks, owner still on the tools |
| $900 - $2,500 | 10 to 15 pages, separate pages for heating, cooling, IAQ and maintenance plans, real photos, review feed, forms routed properly | Three to eight trucks, some repeat and referral work already |
| $2,500 - $8,000 | 20 to 40 pages, service-area pages written individually, embedded online booking, financing prequalification, tracking and call attribution wired up | Contractors buying leads and wanting to stop |
| $8,000 - $20,000+ | Custom design, API work against ServiceTitan or similar, multi-brand or multi-location structures, membership portals, equipment selectors | Multi-location, private-equity backed, or heavy new construction |
Our own web design and development work starts from $200, and that number is a minimum rather than a price. What a specific HVAC site costs depends entirely on the list below.
What actually moves the number
Page count, and specifically service-area pages
A page is not a template slot. A page someone will read and act on takes copy, a photo or two, internal links and a review or job story that matches the subject. Budget an hour or two per page for anything worth having, and price accordingly.
Service-area pages are where quotes swing most. Forty city pages built from one template with the town name swapped is cheap to produce and worth roughly what it costs. Ten pages that name the neighbourhoods, mention the housing stock, reference the local permit process and carry a job you genuinely did there are a different product. If a builder quotes you $60 a page for fifty towns, they are selling you find-and-replace. That work is why local SEO and the website build are hard to separate for a trade business.
Online booking
This is the single biggest jump in most quotes, and it depends entirely on which software you run.
- Housecall Pro gives you an online booking widget you paste into the page. Half a day of work to place it, style it so it does not look bolted on, and test it end to end.
- Jobber and Service Fusion are similar - hosted booking flows with an embed or a link.
- ServiceTitan is the expensive one. Scheduling Pro handles the customer-facing side, but genuine availability-aware booking against your board, with capacity rules and job types mapped correctly, means API work through their developer programme. That is a project, not an afternoon, and it is usually the difference between a $3,000 quote and a $9,000 one.
Before you pay for any of it, check your own numbers. Look at what share of your booked jobs came from a phone call last year. In most residential shops it is still the majority, and a booking widget mainly serves the after-hours crowd. Real value, but not always worth five figures.
Financing calculators
A link to a lender's prequalification page - Wisetack, GreenSky, Service Finance, Foundation Finance, Microf - is free and takes minutes. A monthly payment estimator sitting on your system replacement page is a build.
There is a compliance angle people miss. Under Regulation Z, if your advertising states a payment amount, a down payment, or a number of payments, you have triggered disclosure requirements and need APR and terms shown alongside. So the calculator is not just the arithmetic, it is the disclosure language your lender has to approve. That is why a proper financing widget adds real money to a quote, and why plenty of good contractors stick to a prequalification button.
Design and photography
Template versus custom is a smaller gap than most people expect. Stock photos of a technician who has never been to your state versus a half-day shoot of your own vans and crew is a larger one. Original photography is the cheapest credibility you can buy.
Platform
WordPress is still the default for trade sites that need 30-plus pages and ongoing content, and WordPress development makes sense once you are adding service areas over time. Webflow gives cleaner design control at a higher build cost. Squarespace and Wix are fine for the bottom band and cheaper to run - the constraint shows up later, when you want unusual integrations or 60 pages with structured internal linking.
Why a $500 site and a $6,000 site are not the same product
They look similar on a phone screen. The difference is in what happens after someone lands on them.
The $500 site has one contact form that emails the owner, no tracking, no call attribution, generic copy, and no page for any specific job someone might search for. It exists so people who already know your name can find your number. That is a genuine function.
The $6,000 site has a page for each thing you sell, forms that route by service type, phone numbers that record where the call came from, review content pulled through automatically, speed good enough that a mobile page loads in a couple of seconds on a phone in a driveway, and schema markup so your service areas and hours are machine-readable. It exists to convert cold traffic from people who have never heard of you.
Cold traffic is expensive. In competitive metros, an emergency HVAC click through Google Ads can run $30 to $80. At $50 a click and a 5% conversion rate, a booked call costs you $1,000. Lift that page from 5% to 8% and the same lead costs $625. On 200 clicks a month that is $10,000 a year, from work you paid for once. You can run your own version of that sum in the ROI calculator.
If you are not buying traffic and not chasing it, that maths does not apply to you, and the expensive site does not pay for itself. Be honest about which case you are in.
When the cheap site is genuinely the right call
Plenty of profitable HVAC companies should not spend $6,000 on a website. If any of these describe you, buy the cheap one and put the money elsewhere:
- You are booked out and not hiring. A site that generates demand you cannot service is a cost, not an asset.
- Nearly all your work is referral, repeat or from a builder relationship. Those people are checking you are real. Five clean pages, a licence number, real photos and a phone number does that.
- You are under a year old. Get a simple, cheap, honest site up, then spend the difference on your Google Business Profile, review collection and vehicle wraps. Your Business Profile drives more calls than your site does at that stage.
- You do not know your numbers yet. If you cannot say what a booked estimate is worth to you, you cannot evaluate any quote you receive.
- Commercial and new construction only. That work is sold on relationships and bid lists. The site is a credential.
The one thing not to buy cheap at any size is speed and mobile behaviour. Half your visitors are on a phone, often outdoors, sometimes on a bad connection, and frequently with no heat. Run whatever you have now through a speed test before you spend anything - sometimes the problem with the current site is a 4MB hero image, not the design.
What the build price does not include
People compare build cost and ignore running cost. Ask for both.
- Hosting: $10 to $40 a month shared, $25 to $100 for managed WordPress on Kinsta, WP Engine or Cloudways. Worth it once the site matters.
- Maintenance: updates, backups, security, small edits. Commonly $50 to $300 a month. Ask what is actually in it.
- Content: new service areas, seasonal pages, job stories. This is where the ongoing budget goes if the site is meant to earn.
- Call tracking and forms: CallRail and similar start around $50 a month. Without it you cannot tell which pages produce work.
- Review generation: whether through your field software or a tool, someone has to ask. Reputation management moves more booked jobs in this trade than most on-page changes.
How to spec it so the quotes are comparable
Send every builder the same brief. It should state:
- The exact number of pages, split into service pages, service-area pages and everything else.
- Which field service software you run and whether you need booking embedded or integrated. Those are different jobs at different prices.
- Whether you need financing display, and which lender.
- Who is writing the copy, and who is supplying photos.
- What happens to form submissions - inbox, CRM, or straight into dispatch.
- Who owns the site, the domain and the analytics account when the relationship ends. Get this in writing.
That last one matters more than the design. Sites built on proprietary platforms you cannot export are common in the trades, and the bill arrives when you want to leave.
