Proof from real campaigns

Results from our HVAC work, and what a Cambridge trade can take from them

Our published case studies are HVAC results. Here they are, named and linked, with a plain explanation of the method behind each one and how it applies to other Cambridge trades.

Written by Ali Sedighi, MBALast updated:

Every result on this page comes from our HVAC work, because that is where the Sedighi.ca group's marketing portfolio started. We name each client and link the live site so you can look for yourself. None of them is a Cambridge business, and none is a plumbing, roofing or electrical result. What they show is a method, and that method is what we bring to Cambridge trades.

CombiBoiler.ca: depth on one product

CombiBoiler.ca reached 300% ROI, more than 300 leads a month, and 500+ page-1 rankings for combi-boiler keywords.

What it shows: owning one narrow, high-value product category in depth beats covering everything thinly. The site answers specific questions about a specific product, page after page.

What transfers: a Cambridge roofer who builds the most useful pages in the region on, say, flat-roof replacement for commercial buildings is applying the same idea. Pick the job you most want, then become the clearest source of answers about it.

HeatLand: content at volume, done properly

Over 850 SEO articles went up on HeatLand, and within 6 months its leads had risen by 300%.

What it shows: a large library of genuinely useful articles can bring in steady search traffic and leads, as long as each one answers a real question.

What transfers: most Cambridge trades don't need 850 articles. But the habit of writing down every question a customer asks and answering it on your site, one page at a time, works at any scale. Ten strong answers are better than a hundred thin ones.

Roma Heating & Cooling: organic growth over a year

Roma Heating & Cooling grew organic traffic by 400% in 12 months.

What it shows: search visibility built on a sound website and consistent work compounds over a year. Month three looks modest; month twelve looks very different.

What transfers: patience with local SEO. Owners who judge it after six weeks usually quit just before it starts working. Our local SEO service is planned on a twelve-month view for exactly this reason.

BCWide.ca: speed when the setup is right

BCWide.ca achieved 3× leads in 90 days.

What it shows: when tracking, pages and campaigns are built correctly from the start, results can arrive quickly.

What transfers: for a Cambridge business with spare capacity, a properly built paid campaign plus a website that converts can move numbers within a season. Our Google Ads service is designed for that situation.

HVACDeal.ca: return measured against spend

HVACDeal.ca generated 500+ leads at a 12:1 ROI.

What it shows: measuring return against spend, not just counting leads, keeps a campaign honest.

What transfers: setting a cost-per-lead ceiling before spending, as explained in our lead budget guide, is how you avoid paying more for a lead than the job is worth.

What we can and can't promise a Cambridge business

We can promise the method, the honesty and the reporting. We can't promise numbers, and we won't. Your results depend on your trade, how crowded your category is in Cambridge, how many jobs your crew can take and how quickly you answer when the phone rings.

What we do commit to is a written plan, a cost-per-lead ceiling agreed in advance, and a monthly report that shows calls, texts, emails and cost per lead. If something isn't working after a fair test, we change it or stop it.

How to judge any agency's case studies

Use the same test on us that you'd use on anyone. Ask whether the client is named, whether the site is live, whether the numbers have a timeframe, and whether the agency explains what it actually did. A result without a name, a link and a period attached tells you very little. Ours have all four, and we're happy to walk through any of them on a call.

Frequently asked questions

Do you have results from Cambridge businesses?

Not published ones. The case studies on this page are results from our HVAC work, and we name and link every client so you can check them yourself.

Why should HVAC results matter to a roofer or plumber?

Because the method is the same: pick winnable searches, build pages that answer real questions, track calls to their source and cut what doesn't pay. The numbers won't repeat exactly, but the approach transfers.

Can you promise similar results?

No, and nobody honest can. Results depend on your trade, your competition, your capacity and how quickly you answer the phone. We set targets with you and report against them every month.

Where can I see more case studies?

The full set is on the HVAC.Agency case studies page, which is linked from this page.
