## Most critical reviews (10 lowest-rated)

### 1/5 — Extremely bad app

*2011-01-02*

Not worth a penny! I would not recommend it to anyone, student or professional - Too many wrongs to mention here. This is an open invitation for RIP-OFF... People read reviews before you buy!

### 1/5 — Crap

*2010-01-11*

My 2nd inpuls buy, I seen the price at the time I needed it and said what tha heck. Read reviews prier to buying ppl. This is stuff out of the text book if I would take time I would have found it. Add superheated subcooling do some real work with this program and give people so upgrades. Hurry.

### 1/5 — Needs more work

*2009-11-09*

It did not help me . It still needs more work

### 1/5 — Disappointing

*2009-09-28*

Sales pitch greatly exceeds the capacity if this disappointing package

### 1/5 — HVAC Formulator

*2009-09-22*

Poor quality software and the help file is non existant- not worth downloading even if it were free!!

### 1/5 — Could be better!!

*2009-06-14*

Very generic!! Anybody with any knowledge could guess just as accurate. 

 So if you have very liitle experience, this might be a helpful app, but ge'ez if you have that little experience PLEASE go get some before sizing equipment!

The conversion table is extensive but hardly worth the cost of the app!!

### 2/5 — Very very disappointed in the

*2016-01-23*

App I thought this would be a quick way to calculate the zones of a job from the pictures is showing that you can

### 2/5 — Not As Useful as it looked

*2009-07-16*

I thought that this would be a good application to use at work but found that a lot of it wasn't useful. The formulas can only be used to find a single result. (eg. mixed air formual will only find the final temp. but you can't used it to find the amount of outside air you required to get a known mixed air temp.). Some of the conversions are useless (Meters to Rods? Really? Why bother)
I wonder if this was made by technicians in the field. More useful and flexible formulas are needed.

### 3/5 — Useful HVAC app

*2009-11-15*

Lots of good formulas but agree it should come with metric as well

### 3/5 — not metric yet

*2009-09-13*

Lots of great formulas, more than i could ever hope to use BUT! this app would be good if it had a metric side. The Developer has said it may come in a future update so if you are in OZ i would wait till than.
