I was not at home either time CJS came to our home. Today our issue got resolved ($378 ) A month or so ago we called to get our "cold spots" looked at and to see what we need to do to resolve them ( $450 ish)Tech opened vents and had us leave doors open and turned fan speed up . The cold areas are still cold so I still am unsure on what my next step is to resolve this . Is there a gauge that should of been used to measure where the cold is getting in ? Is this not a HVAC issue and is an insulation issue ? We are $ 800 in and still not sure on how to proceed to get our homes temp more even ( 70 degree ) Thanks Darla
