Great video sir, I am not a fan of the system that you worked on, just for the fact that I am a basic kind of guy, the fancy controls to me are just one more thing to break down. That is just me though.

[@douro20]

They are VERY expensive to service. I would never own such a system unless I could afford the cost of parts. And the ComfortLink HMI is mandatory on these communicating systems.

[@myHVAClife]

@@douro20 No additional cost to service from us, and nothing is mandatory. Annual maintenance is the same as any unit and they have a 10 year warranty.

[@douro20]

@@myHVAClife Hmm...I thought on communicating units you had to have the ComfortLink to be able to use them.

My own back ground in HVAC goes back to the 70's when we became a GE contractor our trucks had, "WE BRING GOOD THINGS TO LIFE" then GE sold the hvac to Trane it always was tough equipment but as a contractor you must maintain a good relationship with your customer Trane equipment cannot be maintained by a non factory trained mechanic and the I have witnessed a lot of butchered units due to inexperienced service.

Im a newer tech. Ran into one of these HP today. Pumps itself down in cool and shows LSPP CLG CO. Switch to heat and showed LSPP HTG CO. Then it ran in Heat at low speed and says Heating Derate. Looking in the previous Codes it has has a low charge code and multiple lockouts…At first I was thinking EEV valve after the LSPP CLG CO but EEV valve ohms good. 13.8v from Distribution board to EVC. ET and GT sensors have proper DC voltage as well… any tips before I weigh out the charge and see if it is in fact “low Charge”? First one of these I’ve ever had to work on.

[@elijahgoodman3140]

Great video. Besides line voltage, everything else is DC volts correct?

[@myHVAClife]

YES, 24v to power the tstat and at the outdoor unit if connecting a load management box. Everything else is DC. Basically only 3 tstat wires to the tstat and 2 tstat wires to the outdoor unit.

I like the umbrella. What kind is it?

Pretty complicated for a straight A/C Condensor? Looks to be very low amp draw, which would save a good amount of electricity? Wanted to get a variable unit, but they are double the price of the one I ended up getting? Are they very problematic, compared to regular units?

[@myHVAClife]

We have been installing these for 8 years, no issues other than the occasional sensor out of range, yes they are costly and over the short term the savings probably does not pay you back completely for the additional cost, but the climate it maintains in the house cannot be matched! These unit do a great job at maintaining consistent temps and humidity levels.

[@DavidWeinberg-cm9xd]

@@myHVAClife The On/OFF system really does suck in a humid environment, like I live in FL? That's why I wanted the variable system, so it's not such a drastic change?

[@bobboscarato1313]

@@DavidWeinberg-cm9xd Well you could get a variable system in about 20 years!

[@chrissipple1018]

It looks like they use a trickle heat system instead of a crankcase heater. Inverter equipment are a bunch of crap, Just to get what .00002 watt savings. I don't know how much wattage you really save but it not worth the money or the problems for these systems. I'm not against you just the inverter systems and the people who buy them. The rich

[@myHVAClife]

I respect your opinion. We have installed over 200 of these units in the last 8 years. And being a TRANE dealer, they have been our least problematic unit from TRANE. Very few problems, a turned off breaker would stop the simplest of systems. I do prefer 'keep it simple' , but I have to learn how to work on what my company installs. The more time you spend with them the easier they are to work on. But yes, They are marketed to a more wealthy consumer. But they have commented on having very impressive reductions in energy costs and a much more balanced comfort level in the home.

[@douro20]

Just don't gasp when you look at the cost of service parts. These are definitely rich boys' toys and I don't envy the people who can afford them.

@@douro20 Well if you go buy groceries or anything else, you know costs have gone up 50 to 60% or more; gas when down a bit but we never know when that will change!
