If it's not one thing...

The HVAC guy came by about 4pm yesterday, and found that indeed the system had suffered a freeze lock due to the extended extreme temps. The temps we are experiencing are outside the performance envelope for the system... and not something we normally see in our area. It has been years.

He also said with the fine dust my shop produces, I not only need to keep the internal unit filters clean, but the coils ckean, blown out, on a regular basis. This is something he never mentioned during installation, guess it never occurred to him. Back up and running.

It has been years since this part of the country has seen temps like this. Hope it's a whole lot more years till we see it again! Glad that you are once again operational.

Went back out to the shop on Sunday and the system was back in Freeze Lock. I can't be upset with the contractor or the HVAC guy, neither of whom could have predicted the two weeks of single digit temps which are highly unusual in our area. The system isn't designed to function in this weather and our HVAC guy is running his behind off right now. We are supposed to get a warming trend for the next couple weeks. I will call him and ask what he recommends... a backup electrical heat system and shut off this unit when we get another spell like this?

The single floor model electric unit is keeping the well insulated woodshop at 60 degrees all on it's own.

Do you have a generator? It seems that the electricity goes out a lot when areas get cold snaps. A generator powerful enough to run the electrical heat in the shop might be handy.

We refinanced a few years ago and did the new roof thing, the added a 20k generac and upped the propane tank from 300 to 500 gallons. It's all automatic, self tests every Wednesday, and can run the entire house and the shops.

Warmer weather. Temps hit nearly fifty and melted the ice and snow. I reset the system.. and it appears to be working fine. We will check into a small propane burner to be wall mounted that is vented, with it's own 20 gallon tank. The other option is to stick with the small electric floor heat, or a larger ceiling mount unit, only for these record low periods. Hope we don't see them often.
