We know HVAC and mobile.

Technology can’t replace the skill and knowledge of a quality HVAC installer or technician, but having technology developed by experienced HVAC veterans at your side can improve the service you offer.

Carmel Software has been in business since 1995 and regularly works with large HVAC companies like Mitsubishi, Trane and others. We’re also a member of ACCA and ASHRAE and regularly attend and speak at HVAC conferences across the US.

We're invested in your success.

These apps will pay for themselves the first few times you use them. Even if your installers and technicians are not currently using smart phones or tablets — one new installation or service contract you win could cover your costs.

We’re continually improving our apps based on collective feedback and technology advancements. Once you purchase an app from us, you’ll receive free updates — lowering the cost investment with every update we push out.

We help you make the most of it all.

Live courses and online videos are available for each of these four apps to get your company up to speed and ensure you’re benefiting from every feature. Visit our site to look at any of the training videos - available at no charge.

You can also connect with us on Facebook, Twitter, Google+ and LinkedIn to get the latest release information and message us with questions.

Securely view and share equipment and service record info in the field.

Right or wrong, your customers believe you should be able to provide details about the services you’ve offered them - whether it was yesterday or four years ago. The HVAC Equipment Locator solves this dilemma. From the field or from the office, you’ll make a positive impression on customers by having access to the location of every customers’ equipment and their service records.

Things like “When was my unit serviced last?” With the HVAC Equipment Locator, the answer is only a few taps or clicks away.

That’s just the beginning. Imagine how much more efficient your technicians become when they can pull up the service history on equipment they’re working on, or how much better your marketing can become because you can identify customers who need their equipment serviced.

 

Available Everywhere

From the field or in the office.

All data entered from the field is stored in the cloud using the same data encryption used by banks. Because it’s available from the Internet, staff back at the office can also access the information by signing into your secure account online.

Calculate loads as you go, explain work and send reports for approval before you leave.

HVAC ResLoad-J offers on-site sizing of heating and cooling equipment, visual reports for your customers and ACCA-approved reports for permit approval.

We all know there are other load calculation solutions out there. So what’s different about the HVAC ResLoad-J mobile app?

  1. Quick, flexible and accurate load calculations — on site. Using ResLoad-J eliminates calculation errors and provides more accurate results. How? We’ve loaded building materials, openings, shading, appliance loads, local weather and other factors you’ll need to get an accurate load calculation report.
  2. On-screen reports make it easier to explain work to customers. Use the built-in reports, graphs and charts to show customers exactly what work you’re doing and why. They will love the transparency and attention to detail — which all lead to a “yes”.
  3. It’s the only native iOS app that’s ACCA approved. Every report you create is ACCA-approved, ensuring the data you send for approval meets ACCA standards. Plus, you can send those reports to authorities before leaving the job site — saving valuable time for approvals.

Reduce your time

As you enter new information on-site, HVAC ResLoad-J applies it. The whole process can cut the time it takes to perform load calculations in half.

Easily explain work

Beautiful on-screen reports help customers have confidence in you and the work you're suggesting - leading to a confident “you’re hired!”

ACCA-approved reports

Reports sent from HVAC ResLoad-J are ACCA-approved, so you can use them for client records, internal use - as well as for permit approval submissions.

Always there

Store an infinite number of load calculations for reference later. You can even use saved calculations as templates for reworks or similar projects.

Once you start using this app, we believe you’ll agree its worth thousands of dollars. It’s available for a one-time fee of $199.99 — no ongoing subscription or renewal fees.

In addition, you can plot individual psychrometric points, create entire HVAC processes, assign airflows, and calculate heat gains and losses. After the chart is complete, you can email a PDF or spreadsheet representation of the chart and all of its data.

Your customers depend on you for comfort.

Word from the field.

Carmel Software HVAC Mobile Apps have been installed over 60,000 times. Here is what a few of those HVAC business owners, installers and technicians have to say.

You should see the eyes of an engineer when I pull out my phone and use this app to how him that I can change the size of his duct correctly because of a beam the engineer “missed” when designing the system. The best is when I go into a home and show the owners why my competitor installed too small of ductwork for their top of the line a/c unit. rikthis, about the HVAC Duct Sizer mobile app

This is the most useful app I have on my phone, as my profession is designing HVAC systems. The app is intuitive, versatile and functional. It fits in my pocket. It’s accurate. I use it every day. Robert Rhinos, about the HVAC ResLoad-J mobile app

This is an awesome app and a great companion to the ACCA approved manual J load calculation app. Carmel Software is my favorite HVAC app developer, it has helped my new HVAC company flourish with their wonderful apps. Try equipment locator yourself and see what I mean. The webinars will help you get up to speed on any of their apps, and their tech support is also excellent and always inviting input to make improvements to their wonderful suite of software. dupedone, about the Equipment Locator mobile app

I have tried three other ACCA approved software programs - none have been as easy to use right of the box as this one. Simple and precise interface that does not require sees of time to understand. I watched a 59 minute video that was clear and easy to follow. Then within 45 minutes I had a block load on a small ranch. There appears to be a lot of depth to the program and much more to learn but I have already produced a useable product in less time than it takes to set up your company data in other programs. Five stars for now and I’d give it six if I could. The HVAC Guy, about the HVAC ResLoad-J mobile app

Four senior R&D execs in our company use it and have never had a problem in F or C. Easy conversion and more flexible than most other apps. There is a small error near 0degF and tiny inconsistencies near saturation but these would only be noticed by a scientist. Great app. maddoggenius, about the HVAC PsychHD mobile app

I have one of those cardboard Vaisala psych calculators, kind of like a ductulator but for psych. calks. Anyway, I’ve been using it for years and it was ok. Now, that I’ve downloaded this app, I much prefer this: it is quick, let’s me specify a large number of input parameters, and instantly displays the results. Good stuff.
