Modern HVAC techs need more than a clipboard and a book of carbon invoices to run their business. Continuing to rely on reference books to make vital calculations out in the field slows service down and can make techs look inefficient.

With the right set of HVAC service apps, you can access the information you need with a tap on your smartphone or tablet. To keep you as efficient as possible, while providing a great service to your customers, we’ve compiled a list of the best 20 HVAC apps for on-the-go technicians. Our list is divided into three categories of HVAC apps: Business Apps, Calculator Apps, and Utility Apps. We’ll start with our own field services business app, ServiceTitan Mobile.

HVAC Business Apps

1. ServiceTitan® Mobile

ServiceTitan® Mobile is the official mobile app of the ServiceTitan platform. You can leverage all the power of our technology to manage your business straight from your tablet while you’re with customers in the field. By giving your HVAC techs ServiceTitan’s full range of software tools on a tablet, you can: 

1. Help techs arrive fully informed.

Job Dashboard in ServiceTitan: Keep all client details organized in one place.

ServiceTitan Mobile gives your techs direct access to every piece of information your Customer Service Rep (CSR) collected when the customer called. They can see customer names, addresses, contact details, outstanding estimates, and even listen to a recording of the customer’s call. No more pieces of paper with scribbled down information, no more repeated calls between CSRs and techs to check on job details, and an instantly more efficient way of organizing work orders and customer information.

2. Review a detailed job history.

Detailed Job History in ServiceTitan: Keeps everything easily organized in one place.

Make sure your techs recognize and greet your regular customers by providing them with a detailed job history for each account. By using ServiceTitan Mobile, your HVAC techs can see:

  • Customer profiles

  • A list of previous jobs provided

  • Prior invoices

  • Photos

  • Voice notes

  • And more…

Not only will your techs be able to treat your loyal customers like friends, but they also won’t try to sell them services they’ve already bought, and can tailor what they offer to each customer’s individual needs.

3. Ditch missing paperwork.

Electronic Work Forms in ServiceTitan: Clients can sign all important paperwork on a tablet or mobile device.

If your HVAC business is paper-based, those papers can easily be lost or forgotten, which delays jobs — or even means appointments get missed. ServiceTitan Mobile avoids this problem altogether by having all customer documents uploaded to the cloud and accessible via each tech’s tablet.

You can trigger specific forms to appear automatically at a specific time in the job cycle, which makes it easy for your techs to remember every step of your sales and service process.

4. Build estimates with just a few taps.

Electronic Pricebook in ServiceTitan: Easily search for products

Using its cloud-based system, ServiceTitan Mobile allows HVAC businesses to manage product and price updates across its entire system. Updates are made in real-time so every tech has access to the latest information, so there’s no excuses for charging the wrong price or selling a product that’s not in stock.

Customers can see the latest vivid, professional-quality photos, watch manufacturer videos, read product information out in the field, and HVAC techs can easily build estimates on the spot.

5. Manage pricing and product catalogs.

Electronic Product Catalog in ServiceTitan: Easily add products to your estimate

ServiceTitan Pricebook Pro, available on both ServiceTitan Mobile and in the office, is a fully integrated pricebook/product catalog that’s easy to update across the system. If you already have a great pricebook, it’s straightforward to import it into ServiceTitan and view it from within our platform.

6. Emulate the online shopping experience for homeowners.

Estimates and Packages in ServiceTitan: Present customers with 3 options to choose from

Let customers browse and buy products and services right on the ServiceTitan Mobile interface. Any customer used to buying online will find it easy to tap and navigate their way through ServiceTitan’s presentation mode and bring the HVAC sales pitch up to date.

7. Close sales on the job site.

Mobile Payments in ServiceTitan: Easily deposit checks and authorize credit card transactions

Using ServiceTitan Mobile, HVAC techs can take payments as soon as the work is completed. Capture check and credit card payments via the tablet’s inbuilt camera (and card payments by swiper). You don’t need to wait days for payments to clear, or chase customers down for payment after the tech has left the premises.

How ServiceTitan’s Automation Improved Performance at One HVAC Company

After being hired as General Manager of Air Comfort Heating & Cooling, Chris Landgrebe quickly found that the contractor’s software was antiquated and started looking for a suitable alternative. He persuaded the company’s owners to opt for ServiceTitan’s HVAC Software.

After some resistance to the new software from techs and CSRs who were trying to use ServiceTitan in the same way as they had used their previous software, Landgrebe called in ServiceTitan guru Kathy Nielsen to train the team on how to use it correctly. The company soon began to reap the benefits.

According to Landgrebe, ServiceTItan’s dashboard automation — which shows calls coming in, displays who is calling alongside their service history, and records every call for future reference — has made one of the biggest differences.

“From an efficiency standpoint, all of the little features we can automate, so I can have my CSR, my bookkeeper, and my dispatcher focus on driving the business, is what's made the biggest difference,” Landgrebe says, “Having everything in one spot is awesome. It's just an all-encompassing software program, and if used the way it's designed, the impact on business is infinite for the positives.”
