Get a cost comparison done to see if the geo is more cost effective for your area. Some air source are getting really good cop's but there is the defrost cost to add in depending on outdoor ambient...

Ice machine descaler works and no glue on any fittings. All fused or barbed and clamped!

Thats whats I use to clean coils (tankless pump) but somthing with a little more flow would be better IMO, and depending on water pipes (domestic or source) I will somtimes use just vinegar.

Gas fireplaces differ in their construction and operation. The newer styles with electronic ignition, power venting, and variable blowers do require maintenance or they typically stop working! As for...

Prepped joints!!! Whats that..... LOL. My guys may wipe the joint off with a rag but I would think thats as far as they go. And yes I have showed, explained, and explained again but no one listens!!!!

Thx Eric. I dont think i need a flow meter unless i'm missing something! I have the proper flow now. Would the pressures change in a nonpressurized loop?

Be very careful with duct sizes as was said. My biggest issue is just that, new unit was installed on air source system and ducting was to small, variable blower will not fix this and u may have...

People that can't do, "teach", people that can't, "do or teach",.......... lie. lol

It is a freeze protected loop (propylene glycol) which is what I use now due to the safety and toxic issues. Yes I know its not the best choice but for me it is the least toxic and safest mix. I am...

So I have a problem. After many years of repressurizing loops on a yearly basis from other installers I have one that we installed 2 years ago that is losing pressure.
Every 6 months I recharge it...

Company just ordered in some SF1 rod and I am not familiar with it. Has anyone used it and what are your thoughts?

Match the hatch LOL. If dont have proper size + or - 10% will work but change to proper size soon and check both run and start amps. kinda hard on motor in my opinion to leave wrong one in system.

Superheat???? If you have a negative SH you probably have no orifice and your evap is now a condensor...... :-O. If your SH is low wrong size!

WOW lots of awnsers. IMO anything below 65f outdoor amb. should have low ambient controls installed be it solidstate or mechanical. This would include cond. fan cycling controls and a freeze stat on...

restriction = high SH, higher than normal SC. also watch head when adding as it will rise rapidly with restriction.(IMO lol)

Jeez I been gone for awhile but things sure have gotten vague around here! 410 or 22? SH and SC? My crystal ball is getting a work out!!! LOL

Does lennox use a micro channel coil?

There is always a chance of shorting compressor (scroll) when pumping down although never has happened to me. I typically reclaim now in all situations just to know what charge is.

Yes it is! What is the issue with unit?

If used as per instructions it does work. I will only use it on older systems that people do not want to replace. R-22 systems that I cannot locate leak after pressure testing. I have used it on 2...

What Dandy me said!!!

Sounds like your real close, we had some issues with York overcharging using ADP coils to get ashrae numbers, most had to have charge removed (few ounces) on start up.

I have heard that 410 will some times have gas bubbles showing even when properly charged so sightglass not always reliable. I will usaully pull and wieght charge to confirm and go from there. "When...
