Does RPM effect motor life? More than I thought it would. "if you change an 825 motor and put in a 1075, your HP load will move from 1/6th to 1/2... with the same blade. and the noise level will go up dramatically in the unit."-vstech, HVAC Talk "Plus you're probably going to eat a few motors in the process."-Six Five minutes sounds about right ...

The thermostat doesn't supply current to close the AC relays; it only acts as a switch. Power for the relays comes from the heating system, through the thermostat (when it has turned itself on) and back down to the relay in question. Anything in that loop -- the wiring up to the thermostat, the connections to the thermostat, the relay itself -- could be a ...

It's all about the temperature/pressure relationship, and how pressure affects the boiling point of the refrigerant. As the pressure of a refrigerant goes up, so too does the temperature and boiling point. When the pressure drops, the temperature and boiling point drop as well. Air conditioning (and some heating) systems take advantage of this, to cool ...

First some background. The HVAC consists of a closed refrigerant loop. At the outside of your home will be a compressor and coils. The compressor compresses the refrigerant and the process of compressing it forces the refrigerant to give off excess heat which is exhausted out the coils. Inside of your home is an evaporator unit with coils. The refrigerant ...

Replace the old thermostat wire bundle with a new bundle with 4+ wires, or Return the new thermostat you have and obtain a wireless version instead. (Examples: Honeywell YTH 6320, Venstar T1100—or the Honeywell RTH 7600 needs only two wires.) The first suggestion might be very difficult. You may have to tear off sheetrock, or do many tricky bits ...

I don’t think there's much of a problem putting the units into storage since they're already in boxes, but do take the extra precaution to make sure that they are padded properly, especially if you're storing them for a long time. Cardboard boxes are just so susceptible to damage and you don't want those units tumbling down all over the place..

Did some further sleuthing and found the capacitor on the unit is shot. Thanks to all for the input.

Check the breaker again by replacing it with a known good one. This is assuming that you know how to disconnect power to the breaker in question! Either buy another breaker or find one nearby that has the same amp rating (mine was the oven/ range). I had the same problem not too long ago. Breaker wasn't tripped, resetting had no effect; only replacing it ...

What you’re describing sounds like a combination of negative pressure in the compartment that the drain pan connected to and an incorrectly sized p-trap on the condensate drain. The depth of the t-prap has to be greater than the negative pressure in inches of water column of the compartment where the drain is connected to. A t-prap with insufficient depth, ...

If liquid refrigerant gets in the compressor, it can indeed cause damage. The compressor is designed to compress gas, trying to compress liquid can burn out the motor. Let the system defrost. Fix the filter. Then turn it back on. If the system still isn't cooling, you'll have to troubleshoot it yourself, or contact a professional to do it. Make sure you ...
