Review: Must have for servicing furnaces. - I was able to use this to confirm a cracked heat exchanger on my old furnace. I also used it to confirm my new furnace was working correctly.
Review: Quality - Please don't buy! I opened it right away and turned it on and gave me O2 sensor code and will not work. I called Testo and they said the O2 sensor needs to be replaced and will not cover it under warranty. I bought three and they are all the same! Don't recommend buying these!

### ⭐⭐⭐⭐⭐ Must have for servicing furnaces.
*by R***G on December 10, 2025*

I was able to use this to confirm a cracked heat exchanger on my old furnace. I also used it to confirm my new furnace was working correctly.

### ⭐ Quality
*by H***C on January 8, 2026*

Please don't buy! I opened it right away and turned it on and gave me O2 sensor code and will not work. I called Testo and they said the O2 sensor needs to be replaced and will not cover it under warranty. I bought three and they are all the same! Don't recommend buying these!

### ⭐⭐⭐⭐⭐ Easy to use, good battery life, decent display
*by A***T on February 16, 2018*

Works well for residential systems, able to quickly tune furnaces and boilers for optimal AFUE. I routinely get 83-86% out of standard 80% furnaces after using this tool. Make sure you know what values to look for when balancing a system, such as excess air percentages and O2/CO2/CO levels, etc. Nice to be able to take static pressures on duct work as well as temperature splits, although the temperature readings take a while to even out. Easy to use, easy to switch from propane to nat gas, only gripe is that it didn't come with the printer. Do yourself a favor and buy the kit that includes the printer. Easy to prove your readings instead of writing down values on your invoices.
