ive just purchased a 3 ton goodman central air system and need a new thermostat for my new system. whats a good brand/model, or deep down are they all the same?? my new system is a conventional air conditioner, not a heat pump. thanks.

A RUUD 1-1/2 ton Heat Pump in a 1200 Ft Sqr home .. Keeps burning the wires off at the Compressor. I have restripped and replaced the Push-On connector on all three wires at least once. Some three times. It seems to run OK while connected, Next door is same size house with same unit, No problems ?? It will run for a day or up to a week then Pop ! After this it takes at least 6-8 hours to cool the house back down. The connection is a Push on type on the wire, And on the motor is a round Stud with a flat for the connector to push on. This connection is always Corroded and rusty looking. So Today I took a dremel and a wire brush and shined the connections. Re done the line wire for the 3rd time and she's running for now..Thinking about just soldering the wires on !! The Air coming from the vents inside is not much cooler than the Ambient, and takes forever to cool down each time it does this.. Any Opinions Welcomed at this point !!!
