My home has 2 HVAC units a large one for the first floor in the crawl and a large one for upstairs in the attic. My problem is with the larger one.
I turned it on yesterday and noticed it didnt seem to be cooling very well. I went outside and the cold line was only cool while the cold line on the smaller unit was cold in comparison. I let both run for a couple of hours. The smaller unit worked fine, but the larger unit froze up and stopped working.
What I noticed. . .
The cold line was only cool to the touch and only a few degrees cooler than the hot line in comparison to my other unit where the difference was very pronounced.
The unit as a heat pump worked okay during the winter though many times I felt it wasnt warming enough.
The unit froze up after about 90 minutes of continuous operation and the blower switched to a very slow speed.
The air filter is new.
This also happened a few times last summer and fall, but I attributed it to a dirty filter.
Is it time to call for maintenance? I thought these things were maintenance free?
Thanks!
