not knowing what you are replacing it with, it is hard to give a reasonable answer ( old sealed units against split system converter ac units )
However if you work along these lines, you will come to a logical decision
First off the old machines had the compressor operation tied to the thermostat setting so the compressor ran full blast until the room cooled to the set temperature. Then it stopped and remain stopped until the room heated up. At this point the compressor restarted and that is the point the the most power is consumed
again it runs full blast until the room again cools and switches off
So you can see that you have a varying room temperature and high energy consumption on start up
Now compare that to inverter units
The compressor is running all the time ( no high energy start ups every 10 minutes or so) but the compressor becomes less efficient as the room cools down
Still running at full rpms but the controls reduce the compressing action--less power to run the compressor--so there is a reduction in power used
The temperature variation is reduced because as the room warms a bit the compressor pumps a bit more gas and doesn't start at full load as per the old unit
Next , the latest units have better temperature / humidity recognition controls so they can be set at night so a room maintains an ambient temperature /humidity so that as the night gets cooler and the air drier you don't wake up freezing
It will even get to the point where you wonder if the unit is working
Lastly you can run the unit at a much higher setting ( 27 Degrees c instead of 24 or less and have the same comfort level as at 24-25 degrees c)
lastly warranty is for 2 years at best and parts will be available for the next 10 years against parts for your old unit
typical central air conditioning system is a split system, with an
outdoor air conditioning, or "compressor bearing unit" and an indoor
coil, which is usually installed on top of the furnace in the home.
electricity as its power source, the compressor pumps refrigerant
through the system to gather heat and moisture from indoors and remove
it from the home.
and moisture are removed from the home when warm air from inside the
home is blown over the cooled indoor coil. The heat in the air
transfers to the coil, thereby "cooling" the air.
heat that has transferred to the coil is then "pumped" to the exterior
of the home, while the cooled air is pumped back inside, helping to
maintain a comfortable indoor temperature.
Central air conditioning can also be provided through a package unit or a heat pump.
Indoor comfort during warm weather - Central air conditioning helps keep your home cool and reduces humidity levels.
- As your central air conditioning system draws air out of various
rooms in the house through return air ducts, the air is pulled through
an air filter, which removes airborne particles such as dust and lint.
Sophisticated filters may remove microscopic pollutants, as well. The
filtered air is then routed to air supply ductwork that carries it back
- Because the compressor bearing unit is located outside the home, the
indoor noise level from its operation is much lower than that of a
free-standing air conditioning unit.
If the unit is running in cold weather than there is ice building up on the coils located outside. This is normal in that the unit is running in heat pump mode heating inside and cooling outside, After the unit detects the ice build up it briefly reverses the cycle heating the outside coils melting(defrosting) the ice which you observe as water on the pad.
sounds like you need to wash your condenser coil. Sounds like your compressor is kicking out on high head pressure. Once it cools off it starts cooling again take it out and give it a bath don't get the electric wet.
t seems like there is a problem with the thermosat, or the compressor. Its not sensing the temperature being to warm to kick the compressor on and cool it down. OR the compressor itself id dead. Hope I could help.
you probably have a defective contactor or start capacitor on condensing unit. if you pretty handy with wiring go to the condensing section open the panel. you should see a contactor (it's the little black piece with all the wires) check the condition of it. next to it is a capacitor and by the problem that you describe it could be that. check it if it looks bloated there's your problem just go an get an combination capacitor and wire up. (make sure the power to unit is off first. any other questions email me @ firstname.lastname@example.org
