I m not sure about some of the other comments but this app is really useful I find it accurate and I love using it in the field to do those quick calcs My clients love it too                     This load calc app is accurate LZ2124

Input is clunky Never sure if you are doing it right and there is no help Can t input direction walls face only windows Room feature main reason I bought it is only 1 2 finished Can input any opaque surface you want in your room as long as its a ceiling w no insulation Can only add items not delete them Text often reverts after editing Because I have no idea if its understanding what I m inputting can t rely on the output         Pretty Poor Music Mike

Wasted 35 don t do it Better pen and paper It s completely waste     Noooo good Tim's Ipod48

I use this for various buildings and rooms at the company I work for and it s amazing the short comings of construction design that are pointed out Which as you can guess brings me to a much mentioned request bring on the commercial building app Please                     Great app dlackey

I downloaded this app and yes it was a little hard to use at first Isn t all software I called Carmel and they got back to me ASAP and trained our guys for 1 2 hour for FREE After the training we knew how to use it much better and now 3 of my guys use it constantly in the field It s a great tool and I love the email capabilities so I can review their work later on Yes it s not perfect like I wish the reports were simpler and more appropriate for customers but they are working on that As far as I know this is the only load calc app out there and it s a great first step in this whole mobile app world Great app and look forward to more                     Good app and great support AirConReseller1001

I have not found this program to be user friendly at all I contacted the company and they asked me if they could call me and help talk me through the program this has been over a month ago and no call This has been a waste of money for me     Owner Papa-J54

This is a good solid load calc app that I use on my iPad out in the field It cranks out good results and I like that I can email them back to the office The screen reports and pie charts look good and they impress my residential customers too I also requested a 20 or so minute training session from Carmelsoft and they obliged Very helpful Now that I ve been using this app I do have a of requests for improvements 1 Allow for some simpler reports so I can send them to my clients directly 2 Add commercial load calc capabilities 1 2 my jobs are at malls or office buildings 3 Add some duct sizing functionality to it Look forward to future updates                     Good solid load calcs but ChillerMan700

I ve been using this app for a couple weeks now at the recommendation of Trane It s been very useful and accurate I ve compared it to my desktop Manual J software and it is the same heating and cooling loads I especially like the fact that when I first downloaded it I called Carmel and asked if they could help me out In fact they offered to train me and a couple of my guys on how to use the app for about 1 2 hour It really made a difference in using it after the training session I would highly suggest being trained The negative comments that have been posted may be due to the fact that they do not know how to use the software properly I would suggest the training Great app                     Great HVAC load calc app HVAC Reseller

It was recommended by Trane to go along with the iPad program After using it and comparing it to other programs I am so disappointed and it s now a joke around the office Our building only needs 1 2 tons So I guess we need to turn on the heat on next time we want to cool off I think Carmel should try another load calc so they can use terms we all know instead of making up new names for loads Bottom line DON T WASTE YOUR MONEY or TIME     Worst ever Cooltall1

I would like a refund this app is useless Extremely disappointed How do I get refunded Gave one star because I had too     Waste of money Twrate

I am a Trane reseller and they suggested we download this app as part of a promotion they are offering us resellers I installed it on my iPad and have used it out in the field with some customers I was able to do a quick and accurate load calc show the customer some graphical reports then email the results back to my office so I could print it out It was quite easy to use despite being based upon Manual J8 which I know can be cumbersome at times I can see using this app almost exclusively out in the field now Great work                     Very useful and accurate Mechengineer1000

I ve been in the HVAC industry for 35 years but until last year had not done anything serious in residential HVAC Most of my work has been in large buildings and industrial processes So I never had occasion to invest in a Manual J load calculation program But this winter when our own furnace started having major problems I thought I d better do a load calc to be a more intelligent consumer I used this program and found it a real delight It s as simple to use as one could ever expect with a Manual J compliant load calc and the ability to tour the house with a laser distance measuring device and enter the data into the iPhone directly was actually quite a bit of fun To cross check the results I was able to download our actual furnace run time for an 8 hour period when the outdoor temperature averaged 4 F below our local 99 6 design value including a 15 MPH wind Our Ecobee web connected datalogging t rh stat is another real delight The actual average furnace output for that 8 hour period was within 5 of my calculated load Pretty amazing Also my calculated load was within 10 of the load calculated by my HVAC contractor who used the far more complex and expensive Wright J software on the PC So I m feeling pretty good about the results from this economical and easy to use program Not that it s perfect It has all the awkwardness and poor assumptions of Manual J itself For example it s exceedingly difficult to find the place where you enter the air infiltration rate for the home And when you get there the interface makes it quite difficult to figure out the correct way to enter the value Really in this day and age when blower door tests allow very accurate measurements of the all important air infiltration number this needs to be much much easier to find and there needs to be a simple way to enter a blower door airflow at 50 PA directly into a well labeled field Also Manual J assumes much lower humidity loads from infiltration that what actually occurs It assumes less than 25 of the actual load in our particular location it s a problem in Manual J itself and this program has no choice other than to follow that bad assumption because it s intended to be Manual j compliant On the other hand the support from the developer was excellent and very responsive He got me on the right track within an hour of my confusion about where to input the air infiltration rate I don t usually expect that level of support in a 24 dollar program Another issue on the negative side is the report output options While the screen reports are excellent and very clear the downloadable HTML report is nearly unreadable for all of the forrest of extra lines and it won t print at any legible size on a single page or even on logical tiled pages Further the spreadsheet version is even worse a huge wide landscape format which even cannot be read on the screen until you ve completely reformatted all the cell widths and even then it s not set up to print on paper in any logical way So the program as it currently stands is essentially useless for communicating the loads to anybody else in any form other than looking at the results on the screen or hand copying the results from the screen reports into an email or other spreadsheet So the non screen reports need a lot of work That said the program still gets five stars from me because after all it provided very reliable results and it was very easy to enter the detailed room by room data I suspect this is going to be very popular with HVAC contractors who need to really do load calcs rather than just guesstimating loads                     Great value and reliable results Lew Harriman

Easy fast and accurate Better than rule of thumb I use it daily for quick equipment sizing Also a great tool for field trouble shooting                     Terrific app AnotherJoe

I m using this and the Load Plus app for doing quick energy audits I know it doesn t quite do the entire energy analysis on these apps but I do email the results back to my office so I can plug it into my spreadsheet and predict energy usage Great app                     Use this for quick home energy audits cooling heating JoeR2000
