R22 but it does not use it it is circulated in a closed loop, if the fan outside is running you may have to pull the brown wire at the split capacitor to see if the compressor is running. Also it is really important that the filters are changed and that the outdoor is clean allowing air to pass through. Turn off power before pulling the brown wire then reapply power for just a second listening for the compressor. If you hear it, turn off power, reconnect fan brown wire. Turn on power and feel if large line is cold to the touch like a good soda can should be around 45 to 55 degrees f. If not cold it need 3 to 4 pounds if the compressor is working which would indicate a leak.

    This depends. if the humming is coming from the contactor and is continuios while being called for yes it is normal.

    If it is a nice rumble low pitch its the compressor running properly.

    If it a hum than off than hum than off, its probably the split cap (looks like a can with wires running to it) which the compressor needs to run, it has a lable with the size I would guess its a 35/5microfarad 440v the five is the fan run cap.

    The refrigerant you will need is r22 and it runs 200-400 us dollars for a 30 lb can it will have a label indicating the factory charge up to a 20 ft. or 6 meters long line set.

Goodman AC unit recently service but don't believe the filter I am using is the issue or what the tech did actually fixed my issue. Details below.

Setting the air handler to high speed will draw more current and this will result in an increase in electricity consumption.

Goodman cple30-1 heatpump. Fan spins. The freon line seem to have adequate pressure. My problem is it wont cool. Any help would be appreciated

I heat pump usually uses a reversing switch that is in the Freon line...and has a coil on it to switch it over from cool to heat...that could be bad, or the control circuit is not telling it to switch over...I would, while in the cool mode, chect the coil volatage and see if you have it.

Where can I find the specs for an earlier Goodman heat pump?

You say 2 to 3 years... I'm assuming the unit is older than that. Especially being r22. What about the first 10 years??? Normally you will get 400 to 500 sqft per ton of cooling, but, that depends on heat load calculations. If the unit wasn't big enough you would have had this issue 10 years ago, not when the system kept running low on refrigerant. At first guess I would say a 2 ton unit is not big enough but if it worked fine for 10 years...wuth all that in mind, if it were me, (a seasoned professional) I would spend 1800 to fix my 15 year old r22 unit before I spent $4000 on a new r410a piece of junk. Best Wishes!!

99 dodge 1500 p/u has intermittrnt heating/cooling in the a/c mode.cools for about 1 minute then blows hot air for about 5 secs then cool again.any thoughts?

You may have over filled the freon. If the a/c system has to much pressure the pump kicks off and on. Hook a pressure gauge to it. Typically these rams take 2 cans of freon. Or 1.8 lbs i think. Your gauge should be in the blue/green area.. Not the yellow or the red. Hope this helps

Rv air conditioner problem

this is true...freon does not fade or get "used up" if freon is needed there HAS to b a leak.
heat strips are very expensive to use....option for the heat pump heating which will only use as much electricity as the a/c side.
heat strips= 220 v X 10kw= 22 amps compared to a compressor at ie= 10 amps.....typical draw for 18,000 btu

Extremely long time to get cool air with 5 ton 13 seer goodman heat pump which is 3 years old.

Check your filter. Make sure it is clean. Make sure the outdoor unit is operational. (power on). Clean your condenser coil with a garden hose. If possible check your evaporator coil. If it is dirty clean it. Your furnace (or air handler) blower speed should be set on high. All of your registers (supply & return) should be open and unobstructed. Check for proper thermostat settings. If none of this information solves your problem , then your units charge needs to be checked. You could be over or undercharged with freon.
Good luck......
