I bought a new condo last year. The HVAC unit is dry walled in, except for the a panel door that opens that allows you to change filter. It also has a green light that you can see.
The problem is that the unit only cools for a while and then the AC no longer works. The green light flashes on unit. To get it working again you have to power off/on whole unit from house fuse box. I don't think there is a problem with the remote thermostat.
Now I have no idea what is wrong, but the problem seems to be happening more frequently.
Am I going to have to get drywall cut in order for service man to look at it ?
