toss the everest in the trash.

What type of HVAC-be specific?

Rheem 1

Mayday 2

Models do make a difference.

IMO

Heat Pump----my specs are
4 ton downstairs 2000 sq ft, 2 ton up 800 sq ft
15 SEER
12.5 EER
9 HSPF
Scroll Compressor
Electronic defrost on demand
Staged backup heat strips

My prefered HVAC installer sells multiple brands....help me choose please

Rheem
Rudd
Maytag

are three brands he stocks/sells

is there any difference if brands are spec'd as above?

Rheem-models of condenser and air handler count.

there are three equally important components-quality HVAC, the install by dealer, and probably the most overlooked and disregarded is the ductwork system.

these are my minimum specs for a new HP system. both outside and inside units should be replaced to have a properly matched system.

15 SEER, 12.5+ EER, 9 HSPF
best matching VS air handler
full BTUs in both cooling and heating for your rated size
R-410a refrigerant(same as Puron)
scroll compressor preferred
electronic demand defrost preferred
thermostat with "dehumidify on demand" feature
staged backup heat strips
new and correctly sized refrigerant lineset
10 yr warranty compressor and parts

you want a thorough inspection of your ductwork system. size, overall condition, supply and return lines, insulation qualities, leak test, etc.

any hot/cold spot issues in your home should be addressed.

I would only use authorized dealers for the various brands that provide quotes. see mfg websites.

I would look at Trane/AmStd,Rheem/Rudd,Carrier/Bryant.

I would not purchase a new HP system that did not have electronic demand defrost.

post back.

IMO

Don't oversize. 1.5 tons is sounds more correct for 800 sq. feet.

4-tons could be a bit too much for 2000 sq. feet. It depends on your insulation, ceiling heights and windows.

Rheem highest efficiency single stage are probably ok. I hear that they don't have some of the features of other brands heatpumps (high-pressure valve?). Atleast the have demand defrost.

I"m not too familiar with maytag brands. I typically don't see them around. Ask your installer if he can get Am. STd or Luxaire/Coleman/York. These brands have demand defrost and make good heatpumps.
