Your business changes with the weather. January is boiler breakdowns and panicked phone calls; July is air conditioning quotes and two-week research cycles. Most HVAC websites are built for neither — one vague services page trying to catch everything and converting nothing. I build heating and cooling sites with a proper path for each season, F-Gas and Gas Safe proof where buyers actually look, and the service-contract page that keeps money coming in when the weather's mild.

The problem
HVAC is really two trades wearing one van livery. In winter you're an emergency service: a family in Barnet with no heating on the coldest night of the year, deciding in four minutes who to call. In summer you're a considered purchase: a homeowner in Richmond pricing up air conditioning for two bedrooms after the second heatwave, comparing three quotes over a fortnight.
Most HVAC websites serve neither customer. They open with "your trusted heating and cooling partner", bury the phone number behind a menu, list every service in one paragraph, and hide the certifications that actually separate you from the unregistered van two streets over. The winter customer bounces because they can't find the number fast enough. The summer customer bounces because there's nothing there to research.
And the biggest miss of all: no service plan page. The firms that survive mild winters are the ones with maintenance contracts ticking away in the background — and customers won't sign up for a plan your website never offers them.
✗ The HVAC site you probably have
✓ The site that earns all year
Three customers, one site
No heating, no hot water, kids in the house, temperature dropping. This customer decides in minutes and phones the first engineer who looks real and available. Your site's job: load instantly, show the phone number in the first thumb reach, prove Gas Safe registration, and state your response time. Everything else is decoration.
Two heatwaves in and they've had enough. AC installs are considered purchases — £1,500 to £3,000 a room — researched over a couple of weeks. This buyer wants install photos, unit options explained in plain English, F-Gas proof, and a clear quote process. A rushed emergency-style page loses them; a proper install section wins the job before the next hot spell.
Landlords, letting agents, small commercial sites. They're not buying a job, they're buying not having to think about heating and cooling again. Plan tiers, what's included, TM44 inspections for commercial AC, and a direct sign-up path. This is the revenue that carries you through a mild winter.
What it takes
Not a brochure. A lead machine that catches the 2am boiler emergency, nurtures the July AC quote, and signs people up to plans while you're on the tools.
"Boiler repair Hounslow" and "air conditioning installation Hounslow" are different searches with different buyers. One combined services page ranks for neither. Dedicated pages for boiler repair, boiler installation, AC install, AC servicing, and heat pumps each rank on their own.
Registration numbers on every page, near every call to action, with a one-line explanation of what each means. Most customers don't know F-Gas is a legal requirement — telling them repositions every unregistered competitor as a risk.
If you're MCS certified, the Boiler Upgrade Scheme is your best content asset. A page that explains the grant process and shows realistic after-grant pricing captures a growing search market most London HVAC firms haven't touched.
Heating emergencies happen on phones. A number that dials on tap, visible without scrolling, on every page. Contact forms are for AC quotes in July, not for a family with no hot water in January.
Plan tiers with prices, what's included, and a sign-up form. Customers who'd never phone to discuss a maintenance contract will happily sign up to one at 9pm from the sofa.
The boroughs and towns you genuinely cover, each with a proper page. Google rewards specificity: "boiler repair Uxbridge" goes to the site with an Uxbridge page, not the one with a coverage list in the footer.
The process
Most projects launch within 2–4 weeks. Booking before autumn? We work backwards from the heating season.
I review your current site, your Google Business Profile, your map pack positions for both heating and cooling terms, and your top competitors. You get a written summary of what's costing you work and the page architecture for the new build — including how the heating/cooling split will work.
Fast, properly structured pages on Astro. Boiler repair, boiler installation, AC install and servicing, heat pumps, commercial — whichever services you actually offer. Per-area pages for your patch. Certifications, click-to-call, schema markup and conversion tracking baked in.
Copy written for how heating and cooling customers actually search and decide, in both seasons. Real photos of installs, vans and plant rooms — not stock radiators. Review integration and final speed optimisation.
Site goes live, sitemap submitted, old site redirected properly so existing rankings carry over. Conversion tracking confirmed. Watched for the first 60 days, with anything Google flags fixed as it appears.
Coverage Area
If you install or service heating and cooling within an hour of central London, I can build the site you need.
Common Questions
A properly built heating and cooling site with separate boiler, air conditioning, and heat pump sections, per-area landing pages, and full SEO foundations starts in the low thousands. Fixed price, quoted upfront before any work starts. A single boiler install typically covers a third of the build cost; one commercial maintenance contract usually covers all of it.
It has to. A boiler breakdown in January and an AC install enquiry in July are different customers, different urgency, different budgets. The site gets distinct sections with their own service pages, their own local landing pages, and their own conversion paths. Google treats "boiler repair Ealing" and "air conditioning installation Ealing" as separate searches, and so should your site.
On every page, near every call to action, with the actual registration numbers. F-Gas for refrigerant work, Gas Safe for gas work, REFCOM membership if you hold it. Homeowners rarely know what F-Gas means, so the site explains it in one line: legally required for anyone touching refrigerant. That single sentence positions you against every unregistered outfit undercutting you.
It's worth building a whole section around. MCS certification is what lets your customers claim the £7,500 Boiler Upgrade Scheme grant, and "heat pump installation + grant" searches are growing every year in London. A proper heat pump page covers your MCS number, the grant process step by step, realistic install costs after the grant, and honest guidance on which homes suit a heat pump. Very few London HVAC sites do this properly yet.
Yes, and it should — maintenance plans are the difference between a good winter and a business that earns all year. The site gets a dedicated servicing page with plan tiers, what's included, and a direct sign-up path. One-off repair customers see a "protect yourself next winter" prompt after the job pages. Recurring revenue starts with the site asking for it.
With its own section, written for facilities managers rather than homeowners. TM44 air conditioning inspections, planned preventative maintenance schedules, response SLAs, insurance figures, and compliance paperwork. Commercial buyers compare three quotes on paper, so the section gives them something to put in the file.
2–4 weeks from sign-off to launch. The usual bottleneck is collecting your certification numbers, plan pricing, and a few real photos of installs and plant rooms. If you want it live before the heating season starts, tell me and we'll work backwards from October.
The website is one part of that equation. Map pack results for emergency heating searches depend on your Google Business Profile, review velocity, and citation consistency working together with the site. Most heating engineers who fix all of it see meaningful map pack movement within 60–90 days, and the free audit will show you exactly where you stand before you spend anything.
Start with the free audit. I'll look at your current site, your Google profile, and how you show up for both heating and cooling searches in your patch — then send a written report within 24 hours. No sales call attached.

Thanks again Dan."
