    I dont think you realize that people lie and they probably sold you 6 lbs of juice and you didnt need it, any tech with half a brain would not add that much and tell you they didnt check for the leak because there isnt one. You need to have them back out and dont pay em another cent. Request a diffent tech you might have a better shot.

    Its that half a brain problem. Too many techs don't use it.

    It appears you had the unit installed in the summer and the tech apearantly charged the unit to proper specification ,6 monthes later the unit needs 6 lbs of refrigerant you system is either severly overcharged or you have a big leak.you should still be in warranty they need to find the problem and fix it ,one quick question did he only use 1 guage or did he use 2 guages and did he use a thermometer

    i am not questioning the techs ability to charge your unit but i do have a problem with how he decided you didnt have a leak

    he put in 6lbs and walked away and now you have refrigerant leaking somewhere and will need 6 more in a short time

    call and ask for a leak check before a problem acures

    Here is an old fashioned "low tech" method.



    Place it in a register that is easy and safe to access. Then start monitoring your temps. When the temps aren't what they used to be something is needing attention.

    He used the one with 2 gauges and a scale. I didn't see a thermometer. He hooked the gauges up and said it was low so he pumped refrigerant until the reading reached a certain level. So you guys are telling me that even with the use of this gauge to monitor refrigerant level that he could still have over charged it?

    Maybe my mind is playing on me but my heat pump sounds a tad noisier. Could this be as a result of overcharging? What are the symptoms of overcharging that I should look for?

    Anyway, yes, it's still under warranty and I didn't pay for the service or the refrigerant. I called them back and they said they would send someone out soon to check to see if any refrigerant leaked out. Is there something specific I should ask the tech to check for the leak or overcharging? Thanks.

    He simply decided after reading the gauge that the initial refrigerant level was low to begin with from the installation. I was a bit baffled for a moment since I told him that the guy who did the installation came back the next day to check for proper refrigerant level.

    Airflow readings.

    Temperatures of:

    Air entering the indoor coil
    Air leaving the indoor coil
    Outside air temperature
    Temperature of the suction line
    Temperature of the liquid line
    Temperature of the discharge line.

    For starters, that should do.

    Not the correct way to do it.

    I would call the company and ask that they send their most senior tech.
