How One HVAC Company Turned Google Maps Searches Into $372K in Revenue

Every plumbing and HVAC owner knows the feeling.

You walk into the office, look at the schedule board, and notice a few too many open slots. A couple of trucks that should already be running calls are still sitting in the lot.

Dispatch is waiting for the phone to ring.

Meanwhile, somewhere in your city, homeowners are searching Google right now because something just broke.

An air conditioner stopped working.
A water heater failed overnight.
A drain backed up in the kitchen.

The first thing most homeowners do is search Google:

“AC repair near me”
“plumber near me”

Google then shows a short list of local companies in the Google Maps results.

And that’s where most of the calls begin.

When someone searches for a plumbing or HVAC service, Google typically shows a map pack with three local companies.

Those companies often receive the majority of calls from that search.

For homeowners dealing with an urgent problem, the process is simple:

1. Search Google

2. Call one of the companies listed

3. Book service

This means that search visibility directly affects how many calls a service company receives.

But many plumbing and HVAC companies never see how that visibility translates into actual revenue.

To understand the real impact, we analyzed five months of inbound call data for a plumbing and HVAC company that improved its Google Maps search visibility.

Over a five-month period, we tracked:

• inbound calls

• new customers

• service revenue

• missed calls

As the company improved its visibility in Google Maps search results, something interesting happened.

The number of inbound calls increased.

More calls meant more booked service jobs—and more opportunities for larger projects.

Here’s what the customer growth looked like.

As search visibility improved, the company began receiving more service calls from homeowners searching Google.

For a service business, that translates directly to something every owner cares about:

More trucks running jobs.

Calls alone don’t generate revenue. What matters is how many of those calls turn into booked jobs.

For this company, the numbers looked like this:

• 80 inbound calls per month

• 25% conversion rate

That resulted in:

20 new service customers per month

With an average service ticket of $550, the monthly service revenue looked like this:

20 customers × $550

$11,000 in service revenue

For many companies, that might seem like the full story.

But in HVAC and plumbing, service calls often lead to something much bigger.

Most HVAC owners know that the biggest revenue often comes from equipment installs, not just service work.

Service visits frequently uncover larger issues:

• aging HVAC systems

• failing water heaters

• major equipment repairs

When that happens, a service call can turn into a replacement project.

Using a conservative estimate:

If 10% of service customers convert to installs, the numbers look like this:

20 service customers
→ 2 installs

With an average install value of $10,000, that produces:

$20,000 in install revenue

When you combine service work and install opportunities, the numbers become much more interesting.

Service revenue:
$11,000

Install revenue:
$20,000

Total monthly revenue:

$31,000

For many HVAC companies, that represents a meaningful increase in business activity.

When that level of inbound demand continues consistently, the long-term impact becomes significant.

$31,000 × 12 months

$372,000 in annual revenue potential

This is the kind of growth that often comes from something deceptively simple:

More inbound service calls from search visibility.

The analysis also revealed something many service companies rarely track closely.

Missed calls.

During the same time period, the company recorded:

51 missed calls

Based on the average service ticket, those missed calls represented roughly:

$8,000 in lost revenue.

For service companies, missed calls usually mean one thing:

A homeowner simply calls the next company in the search results.

The real lesson from this analysis isn’t just about marketing or search rankings.

It’s about understanding the revenue pipeline behind inbound calls.

For plumbing and HVAC companies, the path often looks like this:

Search visibility
→ inbound calls
→ booked service jobs
→ install opportunities
→ revenue growth

When companies start measuring that pipeline, they often discover opportunities they didn’t realize existed.

Many service companies only look at their final revenue numbers each month.

But revenue is the result of a series of events that begin much earlier.

It often starts when a homeowner searches Google for help.

From there the path looks like this:

Google search
→ phone call
→ service visit
→ possible install
→ revenue

Understanding that pipeline can reveal growth opportunities that would otherwise remain invisible.

And sometimes, as this case study shows, those opportunities add up to much more than expected.
