    AC Problem

    My son, who lives in LA, has a problem with his AC which occurs during the hottest part of the year. The unit is a Lennox package unit installed on his roof about one year ago. During the hottest part of the summer (90's), before the set temperature is reached, the unit would shut down and it would say "waiting" on the thermostat for a period of time.. Although the HVAC contractor is responsive, he can not seem to solve the problem. Any help would be appreciated.

    The "Waiting" message is usually associated with an anti-short cycle timer and the system is waiting for the time to expire. That's the symptom, not the disease. The challenge is to find out what's tripping the unit off. It could be a number of things including but not limited to an errant t-stat signal, a pressure switch trip or there could be other controls on the unit that would cycle it off under certain conditions. It's impossible to tell from here but I'd keep after the techs with whom you're son is dealing until the run out of ideas. At that point, you'll probably have to resort to another company. And good luck finding a great tech.
    If YOU want change, YOU have to first change.

    If you are waiting for the 'other guy' to change first, just remember, you're the 'other guy's' other guy. To continue to expect real change when you keep acting the same way as always, is folly. Won't happen. Real change will only happen when a majority of the people change the way they vote!

    Thanks for the erudite response. Since it is still under warranty, would it make sense to request the local Lennox service rep be involved, as well?

    As with all warranty issues, the first issue is to be sure the problem is properly documented within the warranty period. That continues warranty coverage until the problem is fully resolved. That said, if your local dealer can't seem to nail down the cause after a few tries, then yes, I'd recommend appealing to Dave Lennox for some added assistance.

    sounds more like a thermostat issue than something in the unit.

    can't see where anything in the unit would break power to the t-stat causing the "waiting" to be displayed.

    If the lights flicker before the unit shuts off, it may be a power compay problem. If no flicker, then I would think it is a thermostat problem or a thermostat cable problem. One other thing.....If he is in a condo building on 208 volt power, the low voltage may be low. These units usually have a multi-tap transformer set for 240 volts from the factory. The 24 volts then may be only 21 volts which will give goofy problems like this.

    Good luck.
