Answer to a question I received on New HVAC Guide. A company had given him an option to have a TXV or not. I go through the pros and cons.

I have a question
Static pressures are a big deal, I bet 75% of systems are out of spec. because of duct of filter, coil dirty…SP will cause a huge efficiency kill. After I installed my system from scratch the SP was poor not enough supply and too high merv filter, after correcting and SP of .28 runtime was cut 50%.
Don’t forget capillary tubes.
I’ve never had to replace a cap tube or piston in 23 years in business. I’ve replaced at least 100 txv’s. Do you think the extra cost up front, the extra .5 SEER efficiency increase and energy saved was worth spending $500-$1000 replacing that valve, along with a week without cooling? I doubt it.
I install Goodman and Mortex all the time with pistons. They work just fine, charged per the installation instructions and I know I won’t be called back for a bad indoor or outdoor txv when it’s 0 or 95 degrees and the compressor is short cycling on the low pressure switch. My American Standard customers get all txv’s and they pay more upfront. Both have a 10 year parts warranty, but labor, refrigerant, filter drier and misc are not included.
I never sold Ameristar or any other equipment manufactured in China. Thankfully IR just moved Ameristar manufacturing back to the US. Service area Barrhaven??
