Customer Question

Hi Pearl, we have a Trane XV90 and it's not cooling the house. It's on and sounds like it's working but there's a slight breeze of cool air coming out of the vents.

he unit outside is working too.

With the info you provided it sounds like you have a issue with a low refrigerant charge or a restricted air flow a the furnace, this will create a freeze up effect at the indoor coil. look for ice buildup at the indoor and outdoor unit where the copper lines attaches to the unit. If you do..

1- Make sure you have a clean filter in your furnace, if it is very dirty, shut off your ac unit for a few hours to let ice melt with only the indoor fan running.

2- With a clean filter try the AC and look at the outside copper lines, the big one should be wet and cold, with no ice and the small one should be warm, and top fan should be exhausting warm air.

3- After doing step 1 and 2 you still have issues, you are probably low on refrigerant and will need service.

Thanks Luke. I turned off the AC and fan off last night and when I checked the furnace this morning, all the ice build up had thawed. So, I set the thermostat to 72* and when the temperature went up, the AC turned on. And guess what, cool air was blowing through all the vents in the house. Everything is working as normal. Again, thanks for your help.
