How to consolidate several HVAC websites into one strong domain

When consolidation makes sense

Consolidate when you run several sites for what is really one business. Typical triggers:

• branches that each built their own website over the years
• an acquired competitor whose site you no longer want to maintain
• a set of city domains bought for rankings, each with a copy of your content
• a rebrand where the old name no longer serves customers

Don't consolidate a genuine division that passes the independence tests in one domain or many. A specialist boiler or commercial brand with its own customers may be worth keeping separate.

Consolidation also resolves risk. Copied city domains fit the doorway examples in Google's spam policies, and footer links tying them together fit the link-spam examples. Redirecting them removes both problems at once.

Step 1: Pick the hub on evidence

The hub is the domain everything moves into. Choose it on evidence, not preference. For each candidate, gather:

• Links: how many real websites link to it, and which ones (local press, suppliers, associations)
• Branded searches: how many people search for that name in Search Console
• Calls: how many calls it produces each month
• Reviews and profiles: which Google Business Profiles link to it
• Age and history: how long it has been the company's public face

Usually the main company domain wins. Occasionally an acquired brand's site has far stronger history, and it's smarter to move the company onto that domain. Either way, write down why.

Step 2: Inventory every page

Export every URL from each old site. Your sitemap is a start; Search Console's page reports and an analytics export catch pages the sitemap misses. For each URL, record:

This sheet becomes your redirect map. It is the single most important document in the project.

Step 3: Decide what happens to each page

Every old page gets one of four actions:

1. Move. The content is good and unique. Move it to the hub, with light editing.
2. Merge. Two or more pages cover the same thing. Combine them into one better page.
3. Rewrite. The topic matters but the page is thin. Write a proper version on the hub.
4. Drop. No visits, no links, no value. Redirect to the closest relevant page, or let it return a "gone" status if nothing relevant exists.

City pages from old domains usually merge into the location page for the branch that serves that area. If no branch really serves it, drop it.

Step 4: Build the branch pages first

Before switching anything on, make sure the hub has a strong location page for each branch. That's where most redirected location content will land, so it needs to be ready.

Each branch page should carry the branch details or service area, the services it offers, local housing and heating context from your technicians, and current provincial programs linked to official sources. Our location pages service covers this in detail.

Step 5: Set up redirects page by page

Use permanent (301) redirects, from each old URL to its destination in the map. A few rules:

• One hop only. Old page to final page, never through a chain of redirects.
• No mass home-page redirects. Sending every old page to the home page loses relevance and frustrates visitors.
• Keep the old domains registered. Redirects only work while the old domain points somewhere.
• Test before launch. Run every old URL through a redirect checker and confirm it lands where the map says.

Then confirm the hub in Search Console. For an old domain that moves wholesale to the hub, Google's Change of Address tool is meant for exactly this, and it only works after the redirects are in place and you own both properties in Search Console. It isn't for moving a few pages within one site.

Step 6: Update profiles, citations and numbers

The website isn't the only place your old domains appear. Update:

• Google Business Profiles: each one links to its branch page on the hub. Follow Google's guidelines: one profile per real location, with service-area businesses hiding their address.
• Directory listings and citations: business directories, association member pages and manufacturer dealer locators.
• Phone numbers: keep each branch's tracked number on its page, so calls stay attributed.
• Offline materials: invoices, truck wraps and signs can keep the old domain for a while; the redirects will catch those visitors.

Step 7: Watch the first 90 days

After launch, check weekly for the first month, then monthly:

• Redirect errors: any old URL returning a "not found" error needs fixing.
• Search Console coverage: new hub pages being indexed, old ones dropping out.
• Calls per branch: the number that matters most. A dip in one branch points to a problem with its page or profile.
• Branded searches: customers still searching for an old brand should find the hub.

Expect some pages to wobble for a few weeks. If a branch's calls are still down after two months, review its page, profile link and redirects first.

A worked timeline

For a company with three branches and four old domains, a realistic plan looks like this:

That's about five months from start to a settled result. Launch outside your busiest heating or cooling weeks.

Common mistakes

• Launching during peak season. A temporary dip in January costs a heating company far more than one in May.
• Forgetting the old domain's renewal. If an old domain lapses, its redirects stop and someone else can register it.
• Leaving the old site live "just in case". Two live copies of the same content compete.
• Skipping the inventory. Without it, you discover the missing pages when customers complain.

Next steps

Consolidation is a structural change, so measure it properly. Our network reporting service tracks calls and booked jobs per branch before and after. If you're still deciding which sites to keep, start with site ecosystem architecture.
