Performed AC and heat tune super tune up, during inspection found low Delta and diagnosed as bad TXV due to high superheat but normal Subcool. Brought up insulation, has r value of 19 would recommend upgrade to r24 and mentioned also membership upgrade. Needs to go over with husband, none of the recommendations were done today but did highly appreciate bringing up the issues. Customer would like to have a plumber come out Tuesday 13 May to look at their leaking hose bib and kitchen faucet.
