SOURCE: central heat and air

Without knowing more information:

1. The evaporator coil could be frozen blocking air flow.
2. Dirty air filters will block air flow.
3. If it has a 2 or 3 speed motor, the highest speed should be used by the AC setting. It could be a wiring issue here. You
didn't state if this is a new problem or has it always been this way.
4. If it's a belt driven blower, the belt could be slipping.
5. If its belt driven, you might have an adustable pully on the motor, if so it needs to be screwed in as far as possible for max speed.

I had the same issue years ago. It was like that from the day I bought the house. Mine is belt driven, so I simply bought a larger pully for the motor, thus making the squirl cage spin faster, and I get plenty of air flow now.

That's about all I got for Ya...

SOURCE: how do i put freon in my central heat and air my

This job is best done by service tech. You have to know what your doing to be able to charge a system. Plus you have to have EPA card to handle Refrigerant. You need to call service tech. Remember if you have to put gas in there isa leak. Make sure they look for one if you ahve it recharged. A unit can run forever on the same gas. Cost of chargeing an AC can very from 100 to 300 dollars. My suggestion is to ask for a free estimate. So you know up front what it will cost. Rus

SOURCE: no air flow from duct on forced air unit

If there is no air coming through all of ducts, there are several things to consider. If you turn your thermostat to fan on, does air come out? If so you may have a switching|thermostat problem. May need to change out, not really hard you just have to turn off electric mark wires as you remove and turn back on. If nothing changed, make sure the circuit breaker has tripped, sometimes its hard to tell so flip it all the way off then back on. Now try to turn on again. If it comes on you need to find out why it's tripping the breaker, merely resetting it can pose a danger for the future. Professionally servicing the unit is important to the longevity of the unit. Now if you find out that unit is coming on but no air is coming out, it could well be that a duct has blown free and is spilling into attic or crawl space. Sometimes the unit forms an ice block in the evaporative area of the unit. In this case it would need quite some time off to thaw. Also the fan motor may be burned out. In that case you would hear part of the unit working with no output. These are a few of the most common problems with this condition.Most of which needs to be addressed by a Tech

The A/c and heating unit does not cut on anymore. What could the problem be?


Are you sure you have power? Is it 220? if so double check Circut breaker. If it's popped and pops again when you reset, unplug the unit. Try to reset again, If it pops again when you reset, you have major electrical problem call electrician. If it holds, then you have a major appliance problem that is causing the unit to "pop" the circut breaker. If it's a central unit similar diagnostics, but you can't unplug it. So call your Heating service people. It may just be your thermostat if central system, or more.if the Circut Breaker pops.

My corona air conditioner inverter does not produce hot air


these are all in one units, some of them are made like smaller central units and some of these are separate ac and heat units. the heat in the separate ones is run off of a heat strip in the unit it's self the ones that are made like a central unit reverse the flow of the freon in the system to draw the heat from outside. this is not something you can repair very easily yourself. most places require because of the freon that you have a certified HVAC technician to work on them.

I have a Goodman heat pump. With the hot weather that has arrived, the air conditioner does not seem to be pumping cold air. do you think maybe that I`m missing coolant.


Hello
Have you checked filters that they all clean, including the out side condenser unite if yes, then it is posable that the machine is short of gas or that the compressor has lost its capacity to pump.
Thanks

If it does not have a furnace or heating elements for heating, then it is a heat pump, which is rare for a central AC system, but makes sense of the fact that it blows warm air when you reset the pressure switch, which may indicates freon pressure charge problem if your AC system has a reverse valve and uses freon to for heating (heat Pump).

Do you get heating when outside unit runs? if you do, check freon pressure levels and top up to required pressures. The button you depress is a pressure reset switch ... that is if your AC system is a heat pump ... which, as pointed above, it is not common for central ACs.

Are you getting 120 vac or 220 vac at the unit? Check the voltage at the first terminals inside the unit as well as the breaker. You should have 220 vac at the elements and you are dropping a leg some where.
