After days of paying for a response to my heating problem. To date, March 23, I still HAVE NOT received a response. So I call this a RIP OFF. I would never refer anyone to use “just an answer”.

I apologize for the delay. The codes you are referencing, on a typical Lennox furnace would giving you 2 different sets of information. The “H” usually precedes the stage of heating the furnace is currently running in. The next numbers could be an error code (usually preceded by an “E”) or the current CFM level the variable speed motor is providing (usually preceded by an “A”) I do realize that after your current level of frustration this answer sounds Vague, I can give you more information if I look up your particular furnace by model number. (Will be something like G51xx-xxx-xx-x, EL296xx-xxx-xx-xx, etc. please provide the full number with all dashes

What I believe you are seeing is the display upside down.
“H” indicates heating mode“3” is actually “E” to indicate an error codeTherefore, “229” would actually be E 226, and “228” would still be the same (E 228)E 226 indicates that the high pressure switch has failed closedE 228 indicates that the system was unable to perform a successful pressure switch calibration mode.There are multiple situations that could exist to give these 2 errors, but the most likely one is that you have a failed pressure switch.If you have an electrical multimeter and are comfortable troubleshooting, we can proceed. Otherwise, it may be time to call your local HVAC professional to get the problem taken care of.

Poor. It took days to get an answer.
HVAC Technician: hvacdave84, HVAC Technician replied 2 months ago
I apologize. I wasn’t present when your question was submitted. As soon as I saw it I did everything I could. If you rate the service as poor, it reflects on me personally. I understand why you would do that if that is what you choose to do, but I do respectfully ***** ***** if you submit a rating, you rate me and the service I provided, as opposed to the overall process.
