Tip & How-To about Honeywell Heating & Cooling

High efficiency filters come with a cost besides $

Those high efficiency pleated or dust fighter filters will have the 90% or more efficiency in removing particulates, however the CFM or cubic feet per minute of airflow will be greatly reduced, approx 4-500 CFM, and thats worth 1 ton of capacity! So youre 3 ton is a 2 ton now but really clean! On days it seems to be losing the battle with heat remocve the filter for a 99 cent cheapie that flows better, in heat mode they are not as critical in my experience, but summers can be.

What size air filter do I need for a Day and Night 80 plus High Efficiency gas furnace... probably purchased in early 2000 maybe 2004


Measure filter size at point of filter brackets. Should be 1 inch thick. 16 x 25 is common. The accordion or pleated filters are good for cooling not for heat. I call them furnace killers. Much less air flow. Heat exchangers over heat and fail prematurely.

need to fix my 2007 Dodge Ram 3500 dually,6.7 Cummings diesel, check engine light code P2002


P2002 - Diesel Particulate Filter Efficiency Below Threshold (Bank 1)
Description: The powertrain control module(PCM) monitors the efficiency of the diesel particulate filter for a concern. The efficiency of the filter is determined by the amount of restriction in the filter for a certain exhaust flow rate. The diesel particulate filter is preconditioned for 5,000 km (3,107 miles) before the PCM begins to monitor the level of restriction. The test fails when the measured level of restriction is less than the expected level calculated by the PCM. Possible Causes:
  • Dirty air cleaner element
  • Recent manual or thorough diesel particulate filter regeneration
  • Aftermarket accessories and performance modifications
  • Modified tailpipe
  • Exhaust leaks before or near the diesel particulate filter pressure sensor
  • Leaks in the diesel particulate filter pressure sensor connecting hose
  • Damaged diesel particulate filter
Diagnostic Aids: Check for leaks in the exhaust system. Check for aftermarket exhaust accessories and performance modifications that decrease the exhaust restriction. If a new diesel particulate filter was recently installed, verify the diesel particulate filter parameter reset procedure was carried out.
