I am interested in purchasing a mini split for a 400 sq ft boat house. I have been unable to find any consumer reports or consumer ratings on them. Can you tell me if they work well or if I will be wasting my money. If not can you refer me to a ratings site. Thank you

They are excellent and very efficient sytems

i have a muti pass ductless in my home and swear by it so much i went to school for them

I am now a mitsubishi cert expert

and cannot sing the praisees high enouhg for the ductless systems

AC is approx. 145 lbs per cubic ft.

there are 27 cubic ft in 1 cubic yard

60 tons x 2000 = 120000 divided by 145 = 827.58 cubic ft divided by 27 = 30.65 cubic yards

square yards would depend on thickness of AC.

you can take thickness x sq ft to get cubic ft

in concrete 1 cubic yard =

4 inch thickness = 81 sq ft or 9 sq yrds

6 inch thickness = 54 sq ft or 6 sq yards

1190 Sq, Ft requires a 2 1/2 ton A/C (1 ton each 400 Sq Ft)

Assuming the unit is 'cooling' but not cooling it 'well,' I would think the unit is too small.

NOTE: 2000 Btu for every 100 sq ft of cooling space if the room is well insulated. If not - then 2000 btu for every 66 sq ft.

For example - a 12000 btu AC unit should cool 600 sq feet of cooling space if well insulated.

or

400 sq feet if not well insulated.

hope this has helped.

The rule of thumb is 600 sq ft per ton so you should be good with a 3.0 Ton unit.

There are alot of factors when dealing with this problem. Heat Load ( Typical A/C unit is designed with a split of 20 degrees farenheit.) If you measure the temperature leaving the discharge registers, the temperature should be around 20 degrees colder than the air entering the return air grille (Filter Location). Also your unit seems to be a 3 ton; In which this system is designed for roughly 450 sq. ft. per ton and can go as high as 550 sq. ft. on newer homes with more than adequate insulation values. On older homes with minimual insulation the 400- to 450 sq.ft. rule per ton should be observed. Another reason could be that the units needs servicing like a dirty condenser coil or evaporator coil, improper refrigerant charge, etc can all be issues that can result in your problem.

Finally, most typical units or designed to maintain a home 20-25 degrees below outside temperature. Example 95 degrees outside, inside should not be set lower than 70 to 75 degrees, and the 5 degree range depends on the SEER (Seasonal Energy Efficiency Rating/Ratio ) of your unit. Hope I was helpful in giving you some direction in things to look for to resolve your problem.

The AC your landlord installed is rated at 8000 btu which is way too small for 900 sq ft. You need at least a 15000 Btu Air conditioner and a 'well insulated' house to be cool.

A good rule of thumb in the AC business says you need 1 ton (12000 btu) of Air conditioning for every 600 sq feet (if the house is well insulated) - if not - then you will need 1 ton (12000 btu) for every 400 sq feet.

So, if you have 900 sq feet and the house is well insulated you should have at least a 15000 btu unit.

If it's not well insulated you will need 24,000 btu.

Well you have a 3 ton system, it might be a tick small depending on windows and insulation in the house. Make sure you set it at one temp and leave it. Zoneing would also help.

[ one ton per 600 sq ft]. how many sq ft on your house then go from there.

Mar 19, 2010 | Air Conditioners

For every 500 sq. ft. house or a 1-bedroom size new house you need 1-ton of cool . An old house you need a ton worth of cooling for every 400 sq. ft. house or a 1-ton per 1 bedroom size house.

Yes if you have good insulation. It is just right. May I suggest a varriable speed air handler inside. Very quiet and a lot of your effeciency comes from the Air handler. Lower cost to operate.quiet,very good humidity control. cost about 400 dollars more but well worth it. Rus
