Re: Lochinvar burner cleaning
I've seen some rough ones but not as bad as hot rod's picture. I always do a combustion analysis after cleaning. There may not have one done in that pic, ever. The max that I recommend is 3 years between cleanings.
I always remove the back refractory and I use a Dremel tool with a stainless steel wire brush to clean the coils and a feeler gauge between the coils (there is a tool for this). I use CLR or Rydlyme to help break down the deposits. I'm going to try Axiom's product (thanks, hot rod). It takes me about 3 hours to do a though cleaning. This is what it looks like when I'm finished. This was a rough one which took almost 4 hrs.
Re: Near boiler piping/replacement boiler
The piping size is adequate for the load you have connected. 100' of fin tube could supply about 55,000 BTU/hr. Seems like plenty for 1800 square feet? No sense in having a boiler sized larger that the fin tube can put into the space. So a 60- 75,000 BTU/hr boiler would be adequate.
If your current boiler is twice that size, 120,000 or larger it probably short cycles and runs 70% efficiency range.

Re: Near boiler piping/replacement boiler
Three zones with 50'/zone = 150' x ~500 BTU/ft. @ 180° = 75,000 BTU. One inch pipe is fine for that load.
If you really want to do something, pipe it primary-secondary to keep the large boiler happy.

or a buffer tank. a buffer tank is probably the only thing you could do that might come close to paying for itself

Re: New Daikin - AC Mini Split
There is probably no air, moisture or non condensables. You could be pulling refrig out of the oil. Is the compressor cold like refrig is boiling off?
Re: New Daikin - AC Mini Split
Pulling the dissolved refrigerant outta the oil. It takes a lot longer to pull a vacuum on oil in a system that was operating.

Hi, Sometimes a friendly letter on an attorney's letterhead gets a response. 😇

@manlep
Posting on Facebook is your decision I would not go that route at this time. You need to get a hold of the contractor and express you concerns firmly and politely and give them a chance to remedy the situation.
I know you have tried contacting them and it is frustrating that they do not respond. Call , text, send a letter and document, document and document. If nothing else you will be building your case if they choose to not respond
Re: Adjacent bedrooms. ERV / Mini split setup
In the attic run a duct from 1 room to another and use an inline duct fan. Insulate the duct. The suction from the duct fan should be over the minisplit. The discharge from the duct should be as far away from the mini as possible. Add the two wall openings as well.
Will it be perfect? No will it help, yes
