Notes and Remarks
This is one of the most important pages in the report. Notes and Remarks contains a list of all the issues found for each part of the whole-house comfort system:
- High Static Pressure
- Low or high-temperature drops
- Restrictive filter
- Dirty filter
- Blower speed set wrong
- Restrictive fitting
- Undersized ductwork
- Dirty blower
- Melted rings on the water heater.
Also included in the Notes and Remarks area is a checkbox denoting whether the issue remains open or is closed after the visit.
And finally, we include a section for Contractor Remarks. Typically, this is where we share the data we collected:
- What was the TESP: Measured TESP vs Manufacturer-rated TESP
- Temperature Drop: Measured temperature drop vs manufacturer-rated temperature drop
- Restrictive Filter: Pressure drop of filter vs Standard filter drop
- Dirty Filter: Pressure drop
- lower Speed Set Wrong: 400 CFM (Buckets of air/ton) have 3.0-ton blower speed, but it’s set to 4.0 tons
- Restrictive Fitting: Measured pressure of return or supply
- Undersized Duct: We get this data from the NCI Clipboard based on actual duct size compared to the amount of CFM needed for that specific system
- Dirty Blower: A dirty blower wheel decreases the system efficiency.
- Melted Rings: The water heater may not be venting properly ‘ combustion analysis must be done for safety concerns.
Under each item listed above, we have a corresponding picture number.
TAB Deficiency Report – Corresponding Pictures
In this portion of our report, we include all the pictures that correspond to the Notes and Remarks page. We are very specific with the pictures we provide.
- High TESP: From taking a picture of the Magnehelic with the TESP, compared to the rated TESP on the furnace nameplate.
- Low- or High-Temperature Drop: Take a picture of the psychrometer with measured temperatures vs Manufacturer’s heat specs on the furnace nameplate
- Restrictive Filter: Take a picture of the filter
- Dirty Filter: Take a picture of the filter
- Blower Speed: Take a picture of wiring or dip switches on the circuit board
- Restricted Fitting: Take a picture of fittings
- Undersized Duct: Take a picture of the supply trunk(s) and/or return trunk(s)
- Dirty Blower: When the furnace is off, reach into the blower compartment and take a picture of the blower wheel
- Melted Rings: Take a picture of melted rings around hot and cold water on the water heater.
