LOVE2HVAC I love this never ending trade! This channel is about HVAC R education, inspiration and the wonderful people that make it happen. I have separated the videos into playlists with topics such as: Getting started in the trade, the multiple different methods Learn HVAC from the start, a sequential video series to learn for free! People of HVACR, interviews with people of our industry Heat Pumps, gas furnace, class videos and more.
i watched you and subscribed you explain very clearly thankyou what is sad to watch is a teacher talk for 1 hour and not 1 student can answer a question
3 years ago I spent 8900 bucks on a 15 seer Ruud Heat Pump 3.5 Ton. Why is it that my Heat pump does not have a accumulator also does not have a heater on the compressor that belly band that keeps liquid out. Well my Ruud Slugs quite often during start up. Not for long about a minute it does. That is what I was told by my next-door neighbor who is a commercial refrigeration guy. He works on walk in coolers and things. My heat pump sucks so bad , its very loud its got a two blade fan that spins at 1100 Rpms and is very steep pitch wise and is very weak on heat. My old junker was a 2013 Gibson that lasted a whole 6 years and died had Pistons on the inside and out and heated very well this thing with Txv valves on the in and out can't heat much at all. Reminds me of my grandmothers old packaged Westinghouse the air was alway about 83 coming out of the vents so was cold always. I bought me a scratch and Dent 18,000 btu it says York but I was told Midea made it got it for 500 bucks and installed it myself . Its a 28 seer Mini split and it kicks ass cooling and is silent and my bill dropped by 40 bucks.. No Accumulator I can't believe that. They really want them to last just a few years and die..
I would have some add a crank case heater, it's cheap and easy to do. TXV work much much better than fixed offices inside and out. The biggest issues I find with heat pumps is the installation. #1 air flow is always bad. Bad airflow, bad ductwork makes heat pumps suck. I see it all the time #2 installation being a proper vacuum being pulled before the refrigerant was opened and then proper charge. Improper vacuum leads to copper plating and early compressor death. Improper charge because so many techs do not understand superheat and subcooling.
I don't have a service agreement and when I had trouble with my 4 year old TRANE in hot, hot August (burnt capacitor) , the installer took 2 days to get to me. The tech tried to sell me the service agreement and verified that he would've already got to me if I had an agreement (which I'd already figured out). I let him know I'd be finding a new installer on my next system. One that DIDN"T push service agreements and was deeply involved in marketing. I also purchased a backup capacitor ($18) and contactor because the tech guy told me the capacitor would be $130 if not for the warranty. - Plus, I've now found a good local AC guy who'll install my NEXT AC at a fair price and doesn't push service agreements. I'm tired of Service guys interested in the highest profit.
Does a TXV completely close when there's no thermal load? I do not understand why if the superheat is low, and txv is closing, there is more and more liquid in evaporator.
wait what’s the difference between pushing liquid refrigerant back into system via suction line vs purging the liquid hose? how do you make sure whether the liquid in hose goes into suction line or get purged out im confused
Hello sir, when the refrigerant gets superheated won't the pressure also get increased? So then the measured pressure when converted to temp, will get equal to the suction temp. And superheat will be 0.
