  1. Two year old carrier ac/furnace system. I added a Safe-T-Switch to secondary condensate outlet this weekend. I tested switch by holding upside down and after 90 seconds (or so) system went off. I put switch back in place (system comes back on), leave attic and then notice no cold air. I also notice very load compressor outside, which eventually shuts off (with fan continuing). I thought something was fried, so I turned off breakers and left system off about 30 mins. When I turned back on…back to normal…usual quiet compressor with normal cold air. What was likely cause of temporary LOUD compressor and no cold air? Read somewhere that can happen when turning system off and on quickly and is due to “head pressure”.

  2. Good morning,
    I have a Goodman A/C unit with gas heat… The fan blower motor tends to come on intermittently and run for a while and then shut off for a while even with the thermostat off … I have changed the thermostat and the capacitor … Any ideas

    1. It is obviously a low voltage control issue. It could be a bad relay, control board, short in the thermostat wires, a bad thermostat, a bad zone board, a bad motor module, any number of controls that you may have in the mix. Better get a technician to investigate.

  3. I have joined a local HVAC’s list of clients for routine annual service. Following the most recent check-up, the technician recommended I get a hard-start kit installed, because, I believe, of the kind of slow and loud start by the compressor. I am writing to ask your thoughts on the subject in general, and what it should cost. How are “hard-start capacitors different that the regular “run” capacitor? I am reasonably handy and can’t think of a reason why I can’t get a capacitor and install it myself at likely a third of the cost? Thanks for your help. (PS – I have a Lennox unit – a four ton I believe)

    1. I don’t like to use hard start capacitors unless it is a last choice. I only use them when the system has a hard time pushing the refrigerant up two floors and against a txv. Now if the compressor is pulling high start amps and is about to die, a hard start may get you a few more months but is only a stop gap before the compressor finally fails.
