I understand the LRA is going to be much higher, but I don't believe the LRA is used to size breakers or wiring, is it? Or is some percentage of it used? I notice LRA is not even listed on either of my two compressor motors. MrFreeze

Lots of good info here, and thanks for all the helpful responses. First things first, I decided to err on the side of caution and removed my repair bolt. Then I reinstalled it with some red loctite. Permanent fix! But more seriously, thanks for the education on the various governing codes...

Well, if I don't post an install about my new compressor, you can assume you were right, and I am dead. Try to think kindly of me. MrFreeze

I have a 60,000 Btu/hr Reznor in my 32 x 48 shop with 13 ft ceilings. I'm in the Pacific Northwest, so probably not seeing temps as cold as you would, but it will heat my shop from 42F to 60F in about 15 minutes when it is below freezing outside. Just a data point for your consideration. Good...

One of my two air compressors has had an audible leak from the bottom of the tank for the past few weeks. I finally got ambitious enough to disconnect it from everything, lay it on its side, and take a look. Found a pinhole with a rust streak around it. Just to see if I could, I...

This is an excellent point. Condensers and fluid coolers that are designed to run wet require chemically treated and monitored water. Otherwise you will get a lot of mineral deposits built up on the coil (water evaporates on the surface, but things like calcium and iron stay behind) and heat...

I'm sure those heaters are legal in Washington; my builder installed one in my garage in 2018 (Snohomish county). 13 ft ceiling. Mine is propane. Good luck with your search. As mentioned, someone will need to be able to bring a manlift into your space to get this done. But commercial HVAC...

My system is 90% ProPress copper. 3/4" mains and 1/2" drops. A contractor buddy lent me his battery-powered ProPress tool. After I had it all fitted, it probably took a total of 10 minutes to crimp every joint. No leaks yet after 5 years. If I was doing this again, I'd probably do...
