Question about Heating & Cooling

1 Answer

My apartment honeywell a/c is on full crank at 90 degrees on "heat". It doesn't feel warm at all, though it's been on for hours. I have a new filter in, as well. Also, "fan" and "auto" are other controls on this honeywell a/c unit, I'm not certain for sure what that means in detail and how it can save me money.

The "Fan on/auto" switch is desighned to give you the option of running the fan constantly, which continuosly filters the air in gives circulation.

It does not effect the heat or cool modes of the unit. All it does is effect the fan.

On the "Auto" setting, the fan will only come on when the unit is calling for heat, or cooling.

This will save a little bit of electricity, but will not continuosly circulate or filter the air.

What was the temperature inside tha apartment when you first set the T-stat on 90?
What is it now? if it is still climbing and it started out very low, it may just be working fine.

If not, you could have other problems, like low refridgerant (if it's a heat pump) or bad insulation on a very cold night or an undersized unit.

Has it been working properly before or have you just moved in/turned it on?

My Honeywell thermostat isnt keeping my house cool even though the temp is set to 69. Currently 90 degrees in here


Its probably not the thermostat. The air conditioner may be stuck on heating mode. If its a reverse cycle, the reversing valve may be jammed so even when the thermostat is calling for cold air, it stays on heat. If the machine is on heating mode, it should be blowing cold air out of the outdoor unit of the air con. If its on cooling mode, the outdoor should be blowing hot air.

My central heating does not go very warm


There is an over temperature thermostate in the heating system and it is most likely defective.

Have a honeywell thermostat t6575b1003 and my a/c unit wont get below 90, is this a thermostat issue?


Does it feel like 90 where the thermostat is located? If it's not hot in that location, then your thermostat is most likely going bad as far as the temp. goes. If the A/C isn't cutting off, then the thermostat doesn't know what the temp is to cut off. I would suggest replacing it if you have these symptoms. If it feels 90, you need to have the unit A/C unit checked out.

I just installed a honeywell 5-2 progammable thermostate.. Everything is hooked up fine and I have my days, hours wake, sleep, leave...etc all set, but when it goes on.. for example, I have it set for...


You didn't include a model number, so it's hard to know for sure - but I'll take a stab at this one. Many of these t-stats have a programmable offset to reduce "hunting". This can be as little as 1 degree or more than 2 degrees.

This means if you set the offset to 1 degree and the room temperature to about 65 degrees, the furnace will heat the room until the t-stat registers a rising temperature of 66 degrees. The furnace shuts off and will not turn on again until the t-stat registers a falling temperature of 64 degrees. The average is 65 degrees, and prevents the furnace from starting and stopping numerous times instead of just once with the 1 degree offset.

You can further reduce the number of furnace start and stops by increasing the offset to 2 degrees. This would work like this when the t-stat is set to 65 degrees and the room is cool:

Room Temp Furnace
63 On
64 On
65 On
66 On
67 On
68 Off

The room is now warm and heat or furnace is off. The room begins to cool like below:

67 Off
66 Off
65 Off
64 Off
63 Off
62 On

With a 1 degree offset, the room temperature varies +/-1 degree (about 2 degrees total). With a 2 degree offset, the temperature about varies +/ -2 degrees (about 4 degrees total).

Also, when the thermostat shut the heat off, the heat that was made is delivered to the space instead of wasted by sending outdoors - so the room will get a little warmer even though no fuel is being burned. The same holds true at the other end. When the t-stat turn heat on, fuel is burned, but there's little heat until the source has reached the optimum temperature and then the heat is delivered to the space.

I hope this helps & good luck! Pleas rate my reply - thanks!

Cooling Problems


Your filter is clogged. Not the one at the bottom of the unit.The one above the unit. It is like a raditor coils, kind of a bear to get to. We have cats and dogs the filter gets most of the hair but not all.Usualy about 6 bolts to take out.The proublem will be at the bottom of the top filter.
