Heating and cooling is the most seasonal trade there is. The first cold week and the first hot week generate more calls than the rest of the quarter, and every competitor is drowning at exactly the same moment, so the business that answers and books wins work the others physically cannot take.

The rest of the year is service contracts, and that is where the margin lives. A firm with four hundred annual service agreements has a predictable business; one without them has two frantic months and a lot of quiet ones, which is a much harder company to run and a much harder one to sell.

The search side is not separate from that. Searches spike overnight: "boiler not working" in the first frost, "air conditioning installation" in the first heatwave, both with a town attached. Ranking for those means the pages exist, the business is verified where it operates, and the reviews are real and recent.

How a call moves through a heating and cooling business

In season the bottleneck is answering; out of season it is remembering who is due.

  1. Breakdown or booking

    During a cold snap the phone line is the limit, so online booking against real engineer slots takes the overflow.

  2. Engineer and parts

    A second visit for a missing part costs a day, so the appliance history is checked before the van leaves.

  3. Repair and service plan

    The repair is the moment to offer a plan, and it stalls when the engineer has nothing to sign the customer up on.

  4. Renewal next year

    Plans lapse quietly when renewal depends on someone remembering, so the reminder and payment run on their own.

What people in this trade ask us

Can customers book online?
Yes, against your real engineer availability. During a cold snap this is the difference between capturing a booking and losing it to whoever picked up, because your phone line is not the bottleneck any more.
Can we sell service plans through the site?
Yes, with recurring payment and automatic renewal reminders. It is the single highest-value thing most heating firms can add, and almost none of them have it.
When should we build this?
Out of season. A site launched two weeks before the first frost has no ranking history behind it, and the search work needs months to be worth anything when it matters.
Can we keep a history for each boiler or unit?
Yes, by address and by appliance: model, install date, past faults and parts used. An engineer who knows what failed last time fixes it faster and orders the right part first.
Can service plans be paid monthly?
Yes, by recurring card or direct debit, with the renewal handled the same way. Monthly payment usually makes a plan easier to say yes to on the doorstep.

The infrastructure under it

Cloud Servers

Booking traffic arrives all at once in the first cold week, which is exactly when the site cannot slow down.

Backup & Recovery

Service contracts and appliance records are the business, and losing them means losing the renewals too.

What one contract covers

  • One contract. The build, the infrastructure and the work that brings people to it, on one invoice.
  • A named team. The person on the first call stays on the project. No account managers, no handoffs.
  • Operated, not delivered. We keep it running after launch: patching, backups, monitoring and the phone when it breaks.
  • European hosting. Servers in Europe, run by us, with the data staying where you expect it to.
  • Monthly reporting. What changed, what it cost and what it produced, in language you can forward to a board.
  • No lock-in. The code, the domains and the accounts are yours. Leaving is a handover.

A senior engineer walks your site, your search presence and the way enquiries reach you, then writes down the three things worth fixing first.

  2. 02We review the site, the search presence and the enquiry path
  3. 03You get the three fixes worth doing, and what each is worth
