Average Reviews:
(More customer reviews)I received the unit on Oct 2009 and it failed at the end of Dec 2009.
It took a long time to get a replacement unit (from China).
The outdoor unit was replaced (labor not covered) and it worked same as the 1st one.
The problem occurs when the system runs in High Power mode, or when coming out of defrost mode, or when a call for a large temperature change is made.
The system power surges to 3 to 4 KW when it tries to heat or cool the house rapidly.
It's rated power is only 2.6 KW. It's over-load protection normally will kick-in at about 3.6 KW or the 230 line 10A circuit breaker will pop open.
To avoid these shut-downs, I monitor the power use and have alarms set at 2KW & 2.65KW. I try to shut down the Sanyo, before the power exceeds 3KW.
Other than the power surge problem, the system works great. Heating and cooling
of our small home is VERY inexpensive now. With the price of heating oil fills,
I think this system has paid for itself at this point.
We do use back-up oil heat, when the temperatures are less than 10deg F.
If you want more info about system performance, search on 'Sanyo 24KHS72 AC/HP DIY'.
Because of this power surge 'bug', I can not recommend this model (24KHS72).
If, the bug is cured someday, I'll come back and edit this review.
Cheers,
Rich

SANYO: Your Best Choice in Ductless Split Air Conditioning Systems Sanyo Ductless Split Air Conditioner & Heat Pump products offer wide versatility in solving your cooling and heating requirements. The Indoor unit (evaporator) is mounted inside the room, enclosed in a handsome space saving cabinet. It is connected to the outdoor unit (condenser) via refrigerant lines & inter-unit wiring through a 3-1/2 opening in the wall. Since no duct work is required, installation is simple, fast & efficient. There is no need to use up window space or cut large openings in existing walls, which could undermine the integrity of your structure, and even pose security risks. Since the Rotary compressor is located in the outdoor unit, compressor operating noise is virtually eliminated from the indoor. The indoor unit has been uniquely designed to provide Whisper Quiet operation while delivering comfort throughout the room(s). In addition, rotary compressors provide efficient, powerful cooling at the lowest noise levels in the industry. DC INVERTER is outstanding for it's RAPID COOLING & HEATING POWER. As soon as the temperature is reached, it automatically adjusts current frequency temperature fluctuation. It also provides ENERGY-SAVING (which saves your electricity charges) as well as QUIETER OPERATION . Low Ambient Cooling Operation The unit can set for cooling even when the outdoor temperature drops to 41 degrees F (5 degrees C). This is ideal for locations that require cooling even in winter. Low ambient cooling refers to maintaining high-side pressure in the condenser at normal levels at low outdoor ambient temperature by the provision of a reversible cooling fan. Cooling air is then directed across the condenser in the conventional direction when the high-side pressure is above a predetermined level and diminishing the volume of cooling air flow across the condenser when the h...
