Hey guys,
Hopefully someone can help me with this.
So I bought a house 3 months ago. And the AC was working when we tried it on.
We were not living in the house just moving stuff in every weekend so I did not turn the AC back on for over a month.
My fiance is now living there but the AC does not seem to turn on.
It a new Lennox Furnace and AC outside the house, and the controls inside is a Honeywell.
I have reset the Honeywell controller but that did not help.
The 2 LEDS IN THE FURNACE INDICATE THAT EVERHTUNG IS WORKING FINE.
What do you guys think the issue could be?
The fuse? On the side of the house?
Maybe the breaker is bad?
Or maybe its in some kind of hibernation mode?

I also have a question regarding lennox AC because this is the first year in this house and I oftenly read articles which are really helpful. while the AC from is working and keeping the house cool it is only dropping the temp 11 deg and doesn’t seem to be pulling moisture out of the air like we are used to in previous houses. So I check things out and throw some gauges on the system and find that the R22 is low. I have a friend who has his HVAC license so he can service his own rentals so I call him up and tell him to bring his R22 with him. This is where the question comes up. He was taught to never take the Low side above 75 psig. The Label on unit says it’s designed pressure 144 on the low side and 278 on the high side.
It was at 55 psig when I started so I brought it up to 70 psig and said I would ask the experts before I take it up any higher. I feel like it needs more as im getting very little (is supercooling the right term?) like only 2-3 deg. It did bring my temp difference at the unit to 14 deg.
So should I leave it or should is it designed to have a higher PSIG and it needs more R22.

This post is all wrong. No “licensed” Tech would leave a novice to charge a system and Especially on a system with a refrigerant whose use has been banned since 2004.
Plus those are not operating pressures.
this has got to be a scam.KingAC
I am assuming you may well get a more knowledgeable answer on this type of system if you posted on the American version of this forum. Because there are likely to be more Techs conversant with your type of system. If you are still having issues could you advise what particular controller you have?
It sounds at this stage as if the system is not being reset / restarted properly or just it is in Satisfied (Temp.) mode? ( Hibernation Mode is a good way of putting it!)
Logic says it should not be a big problem but long distance and with minimal info. Its rather difficult to diagnose let alone fix.
Good luck all the same. and please let us all know how you get on.TheAChub
I have the Honeywell TH3110D1008. I have changed the fuse in the breaker box and that did not fix it.
I am gonna go buy a new thermostat and see if that fixes it. Because I believe that is the issue.
Anything else I should try?

Hi Follow this link for a manual.
https://manuals.plus/honeywell/th311…e_installation
scroll through to set up and try setting the (Very Basic) Controller.
If this is unfamiliar territory try enlisting the help of someone a little more technical ellectrically.
Good luck
