What BTU rating should I choose for my air handler?

This depends on the coverage area/room size you are trying to heat/cool
An Air Handler's BTU is how powerful the fan is. A higher BTU rating will be able to heat/cool a larger area

Air Handler BTU	Coverage Area/Room Size (Sq Ft.)*
9K BTU	Up to 375 Sq. ft
12K BTU	Up to 500 Sq. ft
18K BTU	Up to 750 Sq. ft
24k BTU	Up to 1000 Sq. ft
36k BTU	Up to 1500 Sq. ft

*Ceiling height, insulation, and local climate may impact the coverage area. For example, an uninsulated room will require more power than a well insulated room.

Decent Company

I ordered a HVAC system and it arrived in a timely manner and with no apparent issues. I thought the system was defective once installed but it was the installers fault who wired it wrong. My only issue would be the fee (30% I believe) to return a defective item within the 30 day return policy. If it is defective the customer shouldn't have to pay a fee to return an item that is not operating as designed. Other than that this is a good company.

Pretty Easy Install and Works Great!

Installed my own central HP system. It was a bit of work but nothing beyond a person with basic mechanical and electrical skills. It took me a while because I had to remove the existing electric forced air furnace from a pretty tight place. Some custom sheet metal work and a bit of custom electrical too. Worked perfectly when powered up and I actually like the thermostat provided, although I wish it was clearer how to set up a temperature set-back schedule. Pre-charged refrigerant piping was something new and I liked that too. The best thing is that my electric utility forked out $4,000 and that paid for the unit!

Installed and working great

Installed with ceiling cassettes... Quiet and keeping us cool so far !

Great unit!

Overall Great Unit and working with HOD was simple. Unit arrived on time and in good shape.

Mr Cool - 36000 4 zone

Install was as stated and works good but struggles at heating house when temperatures are below freezing. I am concerned what will happen once we get to 20 and lower. Over all I like the product but they should be more honest about heating at low temperatures.
