How to choose an Ontario HVAC service area you can actually win

Why the service area matters so much

Short answer: Google's local results favour nearby businesses, and customers favour companies that arrive quickly.

Google says local results depend mainly on relevance, distance and prominence. Distance is fixed by where your business is. If your shop is in Whitby, you'll find it far easier to rank in Whitby, Oshawa and Ajax than in Vaughan, however many pages you write about Vaughan.

Google also sets an outer limit. Its help page on service areas says the boundaries shouldn't be more than about two hours of driving time from where your business is based, and you can list up to 20 service areas. Two hours is a ceiling, not a target. In January, a two-hour drive to a no-heat call is a poor review waiting to happen.

Step 1: draw your realistic drive-time ring

Short answer: start with how far your crews actually go, not how far they could go.

Pull the addresses of your last 12 to 24 months of jobs. Mark them on a map and draw a line around the area where most of them sit. Then ask:

• How long does it take to reach the edge of that area at 8 a.m. on a weekday in winter?
• Which towns inside it produce profitable work, and which produce long drives for small jobs?
• Where would you open a second base if you grew?

For most single-location companies in southern Ontario, a ring of 30 to 45 minutes covers the work that pays. In the North, distances are longer and the ring stretches, but the same logic applies.

Step 2: size each town with public data

Short answer: population, growth and housing tell you how much work each town can produce.

For every town inside your ring, look up three numbers from Statistics Canada:

1. Population and growth from the 2021 Census counts.
2. Occupied private dwellings, a rough proxy for the number of heating systems.
3. Dwelling types from the census dwelling table: detached houses buy residential HVAC differently from high-rise condos.

Add the heating picture where it's available. The 2023 heating survey reports primary heating energy for Ontario and its larger metro areas, such as 85% gas in the Brantford area and 52% in the Toronto area. For smaller towns, Statistics Canada doesn't publish a separate reliable figure, so use your own job mix.

Step 3: scan the competition

Short answer: search like a customer, in each town, and write down what you see.

For each town, search for your three most valuable services, such as "furnace replacement [town]", "heat pump installation [town]" and "AC repair [town]". Record:

• which companies appear in the map results, and where they're based;
• how many reviews each holds, and how recent they are;
• whether they have a real page about that town or just a mention;
• who is running ads.

A town where the map results show companies from 40 minutes away, with few reviews, is an opening. A town where three local companies each hold hundreds of recent reviews is a long-term project.

Step 4: score and rank the towns

Short answer: a simple score turns your research into a decision.

Here's a worked comparison of three real Southwestern Ontario towns, as a London-based company might see them. The census figures are real; the competition and drive-time scores are illustrative, so replace them with your own research.

Give each town points for size, growth and housing fit, then add the drive-time and competition scores. In this example, St. Thomas wins on proximity and detached housing, and Woodstock earns a place because of its growth and lighter competition. Stratford might wait for a second phase.

A note on the numbers

Treat the census figures as a guide to scale, not a forecast. The 2021 counts are a few years old, growth since then won't have been even, and a town's population doesn't tell you how many homes need a new furnace this year. What the numbers do well is rule things out: a town of 5,000 an hour away is rarely worth a dedicated campaign, while a growing town of 45,000 twenty minutes away almost always deserves a closer look.

Step 5: build, then widen

Short answer: win the core, then add one town at a time.

1. Core towns first. Full service pages, a strong Business Profile and steady reviews in the two or three towns nearest your shop.
2. Add a town only when you can say something real about it, such as typical homes, common equipment and realistic arrival times. Pages that just swap the town name risk being treated as doorway pages.
3. Split ad campaigns by town group so you can see what each costs.
4. Review every year. Compare where booked jobs came from with where you're spending.

Common mistakes

Short answer: claiming too much, faking presence and never revisiting.

• Listing 20 towns on day one. You're allowed to; it rarely helps.
• Virtual offices to rank in towns you don't serve from. They break Google's guidelines and get profiles suspended.
• Ignoring growth. Fast-growing towns create new homeowners who haven't picked a service company yet.
• Setting the area once and forgetting it. Your territory should change as your company does.
