How to Grow Your HVAC and Plumbing Business: 3 Strategies

You can grow your HVAC and plumbing business without adding a single truck. Three practical strategies can help you generate more value from your existing team, equipment, and customer relationships:

1. Catch equipment problems before they become costly failures.
2. Keep technicians trained on the equipment they install and service.
3. Expand into a second trade—and offer more services to the customers who already trust you.

These aren’t future-facing ideas. Connected equipment is already making predictive maintenance possible in the field. Ongoing training is helping contractors navigate new technologies amid a growing technician shortage. And more skilled tradespeople are expanding across HVAC and plumbing to create new revenue opportunities. And companies like Rheem are guiding these moves into multi-trade services by offering the products and the training to help you grow.

How can HVAC contractors grow their business this year?

KEY TAKEAWAYS: HVAC contractors can grow in 2026 through predictive maintenance, technician training and expansion into plumbing. Predictive maintenance reduces repeat visits by flagging wear before failure. Adding a second trade raises revenue per customer without raising acquisition cost.

Growth in the trades rarely comes from one big move. More often, it comes from finding—and closing—the gaps that quietly cost your business time, talent, and revenue.

An unnecessary truck roll cuts into labor, fuel, and billable hours. When an experienced technician leaves, valuable knowledge often leaves with them. And when an existing HVAC customer calls someone else for a water heater, it’s a missed opportunity to build up a relationship you’ve already earned.

The three HVAC and plumbing business growth strategies below address each of these challenges, starting with the opportunities contractors may be able to act on most quickly.

Smarter diagnostics can help reduce unnecessary service calls using connected equipment already in the field. Training strengthens your team over time. And expanding into a second trade can create an entirely new source of revenue—though it naturally requires more planning and investment.

Each strategy responds to changes already shaping the HVAC and water-heating industries. We explored those shifts in our look at what changed across HVAC and water heating in 2026. Now, let’s look at what contractors can do about them.

What is predictive maintenance in HVAC?

KEY TAKEAWAYS: Predictive maintenance in HVAC uses sensors on components such as fan motors and compressors to detect wear before failure. Sensors report condition data to a monitoring platform that alerts the contractor. Predictive maintenance shortens downtime and lowers the cost of an emergency call.

Predictive maintenance adds real-time equipment data to the traditional service schedule. Rather than relying only on a routine six-month visit, contractors can use connected system data to identify changes in performance that may signal a developing issue.

In HVAC systems, sensors and connected controls can monitor factors such as electrical draw, cycle duration, and overall system performance. A change in these patterns—such as a motor drawing more current or a compressor running longer than usual—can help technicians determine when a closer look may be needed.

Connected plumbing and water-heating equipment provides a different set of insights. Depending on the system, contractors may be able to monitor flow rates, inlet temperatures, pressure changes, and error codes. These signals can help identify potential leaks, scale buildup, or performance issues before they become more disruptive for the homeowner.

Three types of data can be especially useful:

1. 1. 1. Electrical draw: Changes in the power used by motors and compressors can indicate wear or declining performance.
      2. Cycle time and runtime: Longer or more frequent cycles may signal that an HVAC system is working harder to maintain comfort.
      3. Water flow and pressure: Unusual patterns can help reveal potential leaks, restrictions or scale buildup in water-heating equipment.

For an HVAC or plumbing business, the value of predictive maintenance comes down to better-prepared service calls. When technicians have diagnostic information before arriving, they can bring the right tools and parts—improving the likelihood of resolving the issue on the first visit.

That capability becomes even more valuable as heat-pump adoption grows. Heat pumps outsold fossil-fuel furnaces by 32% in the first quarter of 2026, according to the Building Decarbonization Coalition. Because heat pumps support both heating and cooling, they may run throughout more of the year—creating more opportunities to use performance data to inform maintenance and service.

What should contractors look for in a diagnostics platform?

KEY TAKEAWAYS: A diagnostics platform should show equipment status, fault history, and system details before a technician leaves the shop. Remote diagnostics reduce unnecessary truck rolls. One dashboard across heating, cooling, and water heating avoids running three separate systems.

Most HVAC businesses already have some visibility. The problem is that it lives in three places: One app for HVAC, another for water heating, and a phone call to the homeowner for everything else.

Rheem TotalView^™ is built to collapse that into one view. An all-new platform available to Pro Partners in 2027 uses a single dashboard to monitor, diagnose, and manage connected heating, cooling and water heating equipment.

Whatever platform you evaluate, three capabilities decide whether it changes your dispatch or just adds another login:

1. 1. 1. Diagnosis before dispatch. Fault codes and system details visible from the shop, so the truck leaves with the right part.
      2. Real-time alerts. Notification when a system starts to drift, not after the homeowner calls.
      3. One view across both trades. Heating, cooling and water heating in a single dashboard rather than separate portals.

The test is simple. If a platform does not change what goes on the truck, it is a reporting tool rather than a diagnostic one.

How can training offset the HVAC technician shortage?

KEY TAKEAWAYS: Training offsets the HVAC technician shortage by raising the output of technicians a shop already employs. The HVAC industry is short roughly 110,000 technicians. Plumbing faces a parallel gap of unfilled positions projected through 2027.

The skilled labor shortage continues to make hiring difficult across the trades. The HVAC industry is short roughly 110,000 technicians, according to figures Rheem cited in June 2026, while the plumbing industry is projected to face approximately 550,000 unfilled positions by 2027.

With HVAC and plumbing businesses competing for a limited pool of skilled workers, growth can’t depend on hiring alone. Contractors also need to help the technicians already on their teams build their capabilities, work confidently, and keep pace with changing equipment.

That’s especially important as the technology they install and service evolves. Experience with gas furnaces or traditional tank water heaters does not automatically prepare a technician to work with heat pumps, low-GWP refrigerants, or connected tankless systems. Without ongoing training, these knowledge gaps can contribute to longer service calls, installation issues, and avoidable callbacks.

HVAC technician training can also support employee retention. Providing opportunities to learn new systems and strengthen technical skills shows employees that the business is investing in their growth—while helping the company build a more capable, adaptable workforce.

Inside Rheem’s Innovation Learning Centers

Rheem runs hands-on training for contractors and plumbers at its four Innovation Learning Centers across the US. Classes typically run about four hours.

The format matters more than the location. Each center pairs interactive classrooms with live demonstration labs and virtual reality stations. Technicians work through product tear-downs and real install, servicing and troubleshooting scenarios.

Pro Partners get more than the centers. The training and education pillar of the Pro Partner Heating, Cooling + Plumbing Program reaches further. Interplay Learning covers online simulation work. Graduate Studies courses go deeper on a single specialty.

Two things to plan for before you send anyone to attend:

1. 1. The real cost is technician hours, not tuition. Budget the day out of the schedule, not out of the training line.
   2. Send people in pairs where you can. Two technicians back from the same class hold each other to what they learned.

Should an HVAC contractor add plumbing services?

KEY TAKEAWAYS: Adding plumbing services makes sense for an HVAC contractor whose customers already call for heating and cooling work. Cross-selling raises revenue per customer without raising acquisition cost.

Every heating and cooling contractor wants the same thing: to provide quality service to their community and, in turn, grow a successful business. Moving from a single trade offering to multi-trade is the next step, and here is what it actually takes.

Start with licensing, because it decides your timeline. Plumbing licensure is set state by state. Most states require either a licensed plumber on staff or a separate contractor license, and some allow limited water heater work under an existing HVAC license.

Then decide what you add first. Water heater replacement is the usual entry point for an HVAC shop. The customer base overlaps almost completely and the install sits close to work your technicians already do. Repiping and drain work are a different business with different tools and different call patterns.

Four things to line up before you sell the first job:

1. 1. 1. A licensed plumber, on staff or under contract, depending on your state
      2. Training for the technicians who will run the calls
      3. Parts and inventory for a second product category
      4. A dispatch process that can schedule two trade types without double-booking

The Pro Partner^® Heating, Cooling + Plumbing Program was built for this transition. Rheem merged its separate Rheem and Ruud Pro Partner programs into one multi-trade program in May 2026.

The program also covers reputation management through RepBooster^™, website help through WebSuite, priority placement in the Rheem.com locator, and recruitment support through a MilitaryHire partnership.

Frequently Asked Questions

How can HVAC contractors grow their business this year?

HVAC contractors can grow a business in 2026 through smart diagnostics, ongoing technician training and expansion into an adjacent trade such as plumbing. Smart diagnostics reduce repeat visits by flagging component wear before a failure. Training keeps technicians current on heat pumps, low-GWP refrigerants, and connected equipment. Expanding services lets an HVAC company sell plumbing work to customers who already trust the brand.

What is predictive maintenance in HVAC?

Predictive maintenance in HVAC uses sensors on components such as fan motors and compressors to detect wear before a failure occurs. Sensors report condition data back to a monitoring platform, which alerts the contractor and the homeowner. Water flow sensors and pressure meters do the same job on water heating equipment, catching hidden leaks and pressure anomalies. Predictive maintenance shortens downtime and lowers the cost of an emergency call.

What is Rheem TotalView?

Rheem TotalView is a platform that gives Pro Partners one dashboard to monitor, diagnose, and manage connected heating, cooling and water heating equipment. TotalView surfaces system details, fault history, and diagnostics before a technician leaves the shop. Remote diagnostics and real-time alerts cut unnecessary truck rolls.

Should an HVAC contractor add plumbing services?

Adding plumbing services makes sense for an HVAC contractor whose customers already call for heating and cooling work. Trust carries across trades, so a homeowner who trusts an HVAC company is more likely to book plumbing work with that company than to search for a new one. Cross-selling raises revenue per customer without raising acquisition cost. Larger renovations, new builds, and commercial projects also favor a single contractor who can handle both scopes.

What is the Rheem^® Pro Partner Heating, Cooling + Plumbing Program?

The Rheem Pro Partner Heating, Cooling + Plumbing Program is a Rheem program for contractors who sell and service both heating and cooling equipment and plumbing products. Pro Partners get access to training, product support, and business tools across both categories. The program is built for contractors expanding from a single trade into a second one. Contractors join through a Rheem distributor.
