I recently had a Bacharach analyzer but was disappointed with the breakdowns & sensors, I want to know which is a highly recommended & reliable one thanks!!

Thanks guys I appreciate the information provided

Hello my fellow compadres, I have a couple of questions and would like some feedback. Where is the solenoid valve suppose to be installed on a heat pump inside or outside that’s about 80’ of...

*update everyone…I went back chemically cleaned the evap coil. Evacuated the refrigerant and weighed it back in according to manufacture specs. No issues were detected when I tested heat cycle,...

Thank God for HVAC talk I enjoy the challenges in the field

Hey run, I just updated my profile. Thanks for pointing that out

Is MP the micro- processor board?

Ehsx will take those readings when I clean the evap to eliminate any possible airflow issues and then test again afterwards

Thanks chainik I’m going to keep that in mind on my next trip. I’ll post once I clean the evap coil.

Hi guys, recently starting working on RTU with new company that does commercial & residential work. Ran into a 2 yr old trane RTU heat pump m# WSC060H3R0A03 s# 191816508L. Owner first called a...

Will do pec, thanks

I’m going back to check pressures and will perform process for leaks, pull vacuum and weigh in for peace of mind, thanks for the input!

Hi fellas,
Installed a one zone Mitsubishi MSZ model 12k mini split this past fall. Worked well all winter no issues. Got a call not cooling well during heat wave, went out today and did an...

The vibration was traveling from the heat pump thru the line sets all the way to the air handler

Same way a dirty condenser increases head pressure,amps and compressor becomes noisy..remember there’s a filter inside when the evap becomes the condenser plus it’s warmer when heat is on during...

This is a base model Trane heat pump they kinda make noise during heat mode, the amps increase during winter time causing the motor on the compressor to vibrate and produce noise especially...

I finally found the issue..homeowner had a different company replace the compressor and they never put back the rubber mount legs and the idiot thought that the muffler was a filter drier and removed...

Go for AirScrubber non ozone have one in my supply plenum

I didnt take SH or SC..I also spoke to Trane tech support and he also told me that he would suggest replacing the Outdoor TXV and filter drier

Had a customer call me about a Trane AH causing heavy vibration when the heat comes on, when the unit is in cool mode it all works well with no vibration.. I ran the heat pump in cool mode and...

Hey Dana thanks for the bulletin..i heard these books can be taken to the exam since it’s a open book,correct?

Hey Dana, thanks for the info, I’m in the NoVA area

Oh I’m doing it for me and for the future opportunities..thanks fellas

I carry a Milwaukee inspection camera good size to look thru the burners going into heat exchanger and I also remove the high limit and check them thru there

Just need some advice on to what material/books to review for my master license exam..don’t want to take the exam the second time, also want to prove the doubters

Check the refrigerant pressures, sometimes it’s other things like low refrigerant which can indicate a possible leak,non condensables or not topped off since it’s fairly new.

Replace the board outside..any bets?

My two scents..I reside in VA, and lately a lot of rain..same complaints with VS indoor units about sweating ducts and excessive humidity, turn off comfort R in Trane/American Standard and do the...

HVAC_marc.. i was thinking the same older model of Nest where pretty shotty..I’ll disconnect the Nest from circuit board and see how the humidifier works alone with the furnace only

I had a call that had me scratching my head..Aprilaire 800 steam humidifier causing water to condensate in duct work when fan and furnace is off..humidistat is making a clicking noise..I swapped out...

I remember when I rode with a tech that was pretty good at convincing the customer..he was 6'2" 285lbs tattoos maybe it was his size intimidation who knows but this guy would leave the homes with...

We charge for any type of cleanings but not all homeowners opt to have their spring check performed early in the spring..so I try to do as much with out scamming the customer cause I'm a big believer...

Ok so we are now conducting our spring AC checks and we're running about 3-4 calls daily..I simply want to know what the HVAC world feels when customers decline legitimate recommendations.. The...

Hello everyone..we started pushing these air scrubber as a whole house purifier..do they really work?? Because I also seen other companies pushing the exact same purifier..I took the training class...

Use a megohmmeter to test each individual low voltage wire to find where the short. I went on a call back 3x to replace the fuse,and the last one I bought a megohmmeter n finally I found the short on...

Cool and thanks

I appreciate schooling me to the proper term.. So a straight AC coil will definitely not operate with a heat pump..and the indoor coil has to be matching to the heat pump with a check-txv,rite?

Ok..one of the tech where I work told me he ran into a unit where only the indoor coil and heat pump were replaced not the air handler. He told me that the indoor coil was for a straight ac and...

Are all indoor coils that operate with a heat pump equipped with a bi flow txv let's say using r410 for residential units??.. If not what controls the flow of refrigerant in either direction??..all...

Ok thanks for the info,greatly appreciated.. One quick question while on evap, does a heat pump evap coil contain a checkvalve or is it the same as a straight ac evap? Or should I post a new thread?

You pretty much answered my question..also would low indoor air temp cause a flooded evap since there isn't much heat to remove?? And would liquid flow back to the compressor?

Ok so I know there's no such thing as a dumb question..my question is what is meant by "flooded evaporator" and what are the causes? Thank you..just asking to better myself

Hey all the tips can help

I remember being told once by another senior tech.. Just wanted some confirmation

Can ohming a gas Valve indicate a good Valve..And what reading are good,thanks

We're starting to get cool weather which means heat checks are rite around the corner. I wanted to ask, whats the proper way to check the heat pump its self And then the furnace, thanks

Units were running for a whole day before the owner called in. He stated that the suction line outside had ice on it n our dispatcher advised him to turn it off n wait for the tech to come out. The...

So it's hot and humid here on the northeastern part of the US. I've ran into a couple of ac units, where the symptom is having the indoor coil icing up. Most of the owners are the type that don't...

So I would like to know how everyone feels about having zoning dampers on a one zone hvac unit..reason I ask Is cause I ran into a few problems with motors going fault as well as the damper motor,...

To doc havoc, I was just asking the question about high amps the opposite of when a compressor draws low amps, just a question, sorry for the confusion
