Alert me when someone posts in this thread:

You should get a two stage scroll compressor condenser unit.

A heat pump might make sense.

A two stage unit that spends more time at stage 1 will be better at removing humidity, quieter and more efficient than a single stage system that cycles more frequently.

Systems will be R410a that are high pressure, there can be more noise. Some models are quieter than others.

If electrical KWH costs are high there, it would be wrong to ignore higher efficiency systems costing more.

Some furnaces or air handlers have advanced features that require replacement if the thermostats. Two stage AC or HP also can drive that change. With Carrier Infinity, everything is managed by a 4 wire buss. A friend of mine is sorting out a Lennox system that was a botched install when new. The proper stat was not installed. The proper stat requires 14 wires! 4 wire data data buss starts looking good.

Most AC/HP problems are created by incompetent installers. These can result in equipment damage and shortened life.

You absolutely cannot put a condenser unit at ground level where you are. Get the feet that raise the unit 6-8 inches. A must for HP. For AC only the coils will stay cleaner and have less fin rot/corrosion.

Get a 10 year all inclusive warranty on the system. Things can and do go wrong.

If your old evaporator coil is dirty and fouled, your air filter setup and maintenance is the problem. Get a 4" deep filer installed and use better filters. Use MERV 10-11 filters, your house will be cleaner too.

If filters were not right, the blades in the blower wheel can have the curves filled with dirt. That can be pulled and cleaned then replaced at the time that 24VAC wires are getting done. Condensing furnace secondary heat exchanger would also then be inspected and cleaned at that time.
