So I'm constantly fighting the battle of justifying the higher cost of name brand ductless over the homeowner specials like Mr Cool and Senville. One of the things I tout is their superior cold...

This is a Geostar (rebranded WaterFurnace) retrofit heating system for a house that only had wood heat and electric baseboards so we did underfloor radiant on the main floor using Viega Climate Trak...

Just installed a Chiltrix system to replace a failed geo experiment (not mine) open pump and dump system pulling and dumping into the same well doesn’t work so good!

Used two CX34’s piped in...

Pretty much, yeah but flares. I'm an idiot, flare coupling in the atticspace behind the head was leaking. I soaped it twice previously and got nothing, just now I soaped it again after eliminating...

Stupid freezey juice! Why can’t it just stay where I put it!? But I already soaped all my joints, what else could I check? Maybe isolate the outdoor and indoor & test individually?

So, I installed a Daikin 24K mini-split about 2 weeks ago, started it up and everything ran fine. Got a no-cooling call a few days ago. I go to check it out and unit is just blowing ambient air. I...

FYI a good read on the subject. http://www.mikeholt.com/technical.php?id=powerquality/unformatted/10-7-99&type=u&title=Power

It's "just" one 5 ton compressor and it has a Supco SPP-5 hard start AND an Emerson SecureStart. They had an electrician go over every possible connection from the transformer to the heat pump and...

I questioned that myself but the electrician they had there says it is correct, I can't recall the gauge off hand and it's only about 8 feet from the panel anyways.



Any data logger...

That sounds really uncomfortable unless it's for some kind of utility purpose.

Well the previous owners did, but it seemed related to the heat pump; They blew a few transformers for their 24v track lighting which would dim whenever the compressor kicked in, hence the...

Didn't check the refrigerant pressures this visit as nothing led me to believe there is a problem with the refrig circuit: Source side entering @40F and leaving @35F & side of compressor was cool...

I have a client with a ground source heat pump that I originally installed for the previous owner about 6 years ago and it's been cursed since the first year and I'm wondering if anyone might be able...

Where do you see black iron?

Exactly, so obviously the loop piping isn't working as an impromptu expansion tank, you're relying on high loop pressure as a safeguard. With a proper expansion device in the loop your pressure swing...

I've seen plenty of properly sized loops with "air issues" that stem from not having a means of buffering the expanding & contracting fluid that leads to pump cavitation & death. By your rationale I...

There is no way SDR11 HDPE will have enough flexibility to accommodate even the most minute volume...

Knipex Plier-Wrench. Don't be fooled, it may look like one of those handyman auto-adjust pliers business but these really work. Way less slipping potential than an open end wrench and slim profile...

Good choice, upgrading the envelope & reducing the size of the heating plant is money in the bank. It's probably too late but I would also incorporate window overhangs into the architectural design...

It blows me away that installing ground loops with nothing done to account for normal expansion & contraction of the loop fluid is still considered industry standard. Any closed fluid loop needs some...

Well that was easy! (once I sorted out the rats nest zone wiring job left by the original installer, sheesh!) I used the 012 base plates so they look real tidy, wiring was waaay easier compared to...

Climatemaster has one too, it's known as the THW. I've only installed one, for my dad. It replaced an old oil boiler, it's heating cast iron rads & an indirect water heater. Been running well for...

Wow, all this sounds sooo familiar. About 90% of the CM heat pumps I've installed in the past 4 years have had txv issues, many replaced multiple times. Manufacturer told me it was a known issue but...

I think the Wera insulated set cost me $45. Came with this dorky wall hanger that I promptly threw away.

I'm looking at replacing my ragged old Extech digital thermometer and was fishing for some recommendations. I was looking at the Hilmor one at my local supply house, I liked the small size and clean...

I love the Wera screwdrivers, hands down best handles i've ever used. Got a great deal on a 6 pc insulated set. The micro drivers are great as well, plus you can get an antistatic version for working...

Anyone used the new tekmar 5 (518, 519, 521) series stats yet? They are to replace the long running standard 5 (508, 510, 512) series which were great (i've installed a gazillion of em over the...
