Is it working?

[hammy233]

Hello I type this while it is -27c outside...I Have a Armstrong Air Handler in the basement with the electric heat strips....I am running on emerg heat now as ..1. It is too cold for the pump and 2. the pump is pooched(another story)...the air handler too me seems to have a rough time keeping the house warm(1100sqft)...I have felt the duct just above the airhandler and it is warm..not hot..I have a thermometer on the closest floor register...it is registering 26c....I opened the front of the air handler last week and checked the serial/part numbers on the heat strip kit.....it is as follows
AEHBCC15CSA, installed in a BCZ24D08N00A handler. I ask this.. should things feel and register hotter, how can I check...and from what I have gather the heat strip kit is designed for a larger style handler....

not good at conversion from C to F but if my calculation is correct, you are about -15 deg fah outside temp and your supply temp at register is about 77 deg fah which is low. Please confirm.

what area do you live?

what is your stat set at? is home's inside temp being maintained?

is your air handler running continuously or cycling at all?

do you know the size of your heat strip? I am just guessing from the number which looks like a 15 KW which is about 50 KBTUs.

I will offer an opinion. either your heat strip is defective and needs replacing or it is undersized for the weather you are experiencing.

post back.

I`m up on the north shore of Lake Ontario east of Toronto....you were close the Temp in F is -13F and the last time I checked the register temp was 80.6F......the Handler runs until the T-stat is satisfied...the t-stat is set at 70F...the heat strips are 15kw total...yes 51182btu`s...it seems to run longer than normal.....when the heat pump was working normally the duct/plenum above the air handler felt alot warmer...

I still believe the supply register temp is low. this could be to several factors such as the extreme outside temp, inadequate ductwork insulation, and even a defective heat strip.

but with your inside thermostat setting being maintained and your air handler actually cycling at what I consider extreme conditions, I would say you are doing just fine. at what temp will you allow your outside HP condenser to come back on for normal operation?

you may want to have heat strip checked at next time your system is serviced.

IMO
Good Luck!
