    If you look at the compressor inside the O .D. unit while it's running, there should only be about a one inch ring of sweat where the suction (larger) line connects to the compressor. If there's much...

    Does your thermostat have a "CIRC" setting for the fan? If so, this setting will circulate air for about every 12 minutes out of 30.

    If it's shorter 1-3 minute bursts of air, it may be there's a...

    They're giving you bad info about the line sets having to be that long. As someone already pointed out, they have to be a MINIMUM of 10 feet. There's also a maximum length per line set and a total...

    An air conditioning system needs to move about 400 cfm per ton. If you have a 4 ton unit that's 1600 cfm. Your bedroom may only need and have ducting to carry 300cfm. The IQ drive can modulate down...

    Poor reviews are usually due to the misconception that when something goes wrong the appliance is to be blamed. In reality, 98% of the time, the installer is the one who should be blamed - especially...

    Look at your chimney outlet with the boiler firing and hot. See any steam?

    Is there any hidden piping that's not visible?

    Not only will a heat pump water heater not give you enough btu's, but it won't give you hot enough water for the AHUs unless their coils are way over-sized and the blower speed is drastically lowered...

    Not a good idea, using a timer.

    Unless that's a condensing boiler by design, it will become one if you do what you're proposing.

    What the tenants are doing doesn't make sense. Between what...

    That boiler is made by Utica. I'd call their tech support. 315-731-4163 Todd's direct line.

    You might also look for some debris "flapping" around in the gas line. Also keep your manometer on the...

    Those numbers don't add up, but you have too little fuel pressure. That has to be set correctly before combustion readings are taken.

    Two gauges reading 25+ and one relief valve dumping. I'd say the odds are in favor of these three components being accurate.

    How the system is piped and pumped can also effect the pressure in each...

    I can't see why you would need five different temps unless there are five different types of emitters.

    Do you know the heat loss of the house and the output of the boilers?

    I think that distributor designed it primarily for how many components he could sell.

    No, you can't get any proprietary parts in the U.S. However, things like the ignition module, gas valve, aquastat, etc. are standard Honeywell parts.

    Your pressure is definitely too low. It should be 12psi cold for a one story bldg, 15 psi for two story, 18 psi for a three. That's conservative.

    Whistling is usually caused by the flow velocity being above 4 ft. per sec. It could be that scaling has reduced the internal diameter of the piping enough, but if that's the case, you have other...
