Informational applications — or "apps" —for hand-held devices are among the most important technology tools now available to the HVACR industry. Need a duct sized? There's an app for that. Need to provide a service estimate? There's an app for that.
Stephen Roth, a principal with Carmel Software, Carmel, CA, estimates there could be at least 100 HVAC-related apps currently on the market, or in some cases, available to cloud computing users. App functions range from simple calculations, to reference, to complex multi-project calculations. App benefits include time saving, convenience, improved efficiency, and a reduced need to rely on outside sources for on-the-job information.
"Apps can easily be used in the field without waiting for a computer to boot up, and the size of a hand-held device makes it easy to carry them around on a roof or around a house," Roth says. "Additionally, Carmel apps lets users email research findings to an office desktop, so they can do more in depth analysis back at the office. And, the more we can encourage technicians to use technology the more attractive HVAC can appear as a career.
Roth says the most popular HVACR apps currently in use seem to be those related to duct sizing, load calculations, and equipment maintenance. Carmel Software developed the app for Standard 62.1 of the American Society of Heating, Air-Conditioning Engineers (ASHRAE), as well as ASHRAE’s duct fitting database, which calculates duct pressure loss.
Apps can be obtained either at no cost, or for a nominal fee, depending on the developerBfore purchasing, the user should verify the level of support they will obtain from the app provider.
Among the HVAC contractors who have latched on to "favorite" apps is Paul Hoy — also known on the HVAC-Talk discussion forum as "Servicepro" — with Global Heating Services, Alberta, Canada. He tells ContractingBusiness.com that the Good Reader for iPod Touch, is efficient at uploading printed data files (PDFs). You can find it at: http://bit.ly/goodreadapp.
"Now, I carry important data with me to the jobsite, that would normally only be on my office computer," Hoy says.
"One example is blower performance data and other important technical data that I always need. I can cross reference sheets on universal parts, credit card phone-in data for processing transactions on-site, and a pricing multiplier, for parts markups, just to name a few.
"I can also upload maps to find directions, and maps of trailer parks, which is very helpful when trying to find a house with an odd address. Resiszing the PDFs on an iPod is very easy," Hoy adds.
Original equipment manufacturers are also "getting into the app." For example, Goodman and Amana brand dealers can find product and distributor information at mobile.goodmanmfg.com.
The Smart Contractor Mobile HVAC App will provide warranty information, a distributor locator, and product information based on product serial number. The app can be viewed on a smart phone or computer, and doesn't require a "www" prefix.
"When dealers enter the serial number of a Goodman or Amana brand unit, they have instant access to the warranty information regarding the unit, compressor information, parts information, technical literature and more," says Rex Anderson, director of communications for Goodman Global Group, Inc. He adds that the app is getting a workout, with more than 80,000 'hits' per month.
Anderson says several enhancements to SmartContractor will be released over the next several months.
The following is a selection of other apps we’ve found for a variety of HVACR news, service, or office-related purposes.
