What an HVAC website should actually cost
The honest breakdown by tier, what you get, what you don't, and how to decide — without inventing numbers.
The four tiers you'll actually see
Pricing for a small HVAC website falls into four buckets. Each publishes its own rates, so instead of a made-up "average," look at the vendors themselves and pick the tier that fits how much you want to touch it.
1. DIY builder — free to ~$30/mo
Squarespace, Wix, WordPress on a cheap host. You write the copy, you pick the template, you wire up the form. Costs almost nothing in dollars and a lot in your Saturday nights. The failure mode is what happens after you finish it: no one updates the site, no one wires up local SEO, and it slowly stops driving calls.
2. Freelance designer — one-time $1,500–$6,000
A local designer builds a five-page WordPress or Webflow site. You own it, it looks better than DIY, and you'll re-pay the same person every time you need a change. This tier is fine for a shop that doesn't plan to iterate. Ask for hosting, form-inbox, and a plan for who handles emergency edits before you sign.
3. Trade-focused agency — $2,000–$8,000 setup + $200–$1,500/mo
Agencies that specialize in home services bundle the website with local SEO, Google Business Profile management, and sometimes paid ads. The monthly retainer is where the real money is — and where the value lives, if they actually rank you. Ask for the last three client sites they built and check whether those sites are on page one for a real service term in a real city.
4. Launch-kit platform — flat $79–$199/mo
A trades-specific platform (Relay is one) ships a full site, lead inbox, and — in Relay's case — an AI receptionist for one flat number. No setup fee, no per-seat, no per-minute meter. The trade-off is you use their templates. If those templates are already tuned for HVAC search intent, that's a feature; if they're generic, run.
How to decide between the tiers
Three questions in order:
- Does the site have to answer the phone too? If yes, tier 4 is the only one that bundles it — everyone else assumes you have a receptionist or an answering service. And you should want it bundled: according to Invoca's analysis, 62% of home-services customers call a business during their purchase journey, and Invoca's home-services data shows 18% of those calls go unanswered on weekdays and 41% on weekends. A pretty site that doesn't answer the call is a $0 investment.
- How much of your book comes from the site vs. word of mouth? A referral-heavy shop can live with a DIY brochure site. A shop that lives on Google needs someone whose job it is to keep the site ranking — tier 3 or a launch-kit platform that publishes locally-tuned pages for you.
- Will you touch it again? Every tier decays if you don't. Freelance sites go stale first (nobody to call), agency sites go stale when the retainer ends. Platforms stay fresh only if they actually keep publishing new templates and local pages.
What a website is really worth
The right way to price a website is against the calls it will drive and the calls it will save. Run your numbers in the missed-calls cost calculator — even if your site cost is only "one $7,500 install" or "twenty $300 service calls" a year, the math is usually not close. According to HomeAdvisor's 2026 HVAC cost guide, a full install runs $5,000 to $22,000; a single one clears a year of tier-3 retainer.
What the website has to include to be worth any of these prices
- A mobile-first request form above the fold. Half your traffic is a homeowner with two bars in a driveway.
- Your license number visible on every page. The specific trust signal state homeowners look for.
- Real photos of your jobs and trucks. Stock photography reads as fake — and according to TCN's 2023 consumer survey, 74% of consumers will abandon a brand after one bad experience. The first impression counts double.
- Local SEO structure. HVACBusiness JSON-LD, per-city landing pages, real sitemap. Otherwise you're invisible in the map pack.
- A lead inbox you actually check. Ideally with SMS notification. If leads sit in an email inbox for three hours you've already lost them — see the HBR 5-minute rule.
Pick the tier, then price the leak.
