About the only thing that it could be is a dirty coil,or some one over charge the system, I have seen just a layer of dust cause the compressor to cycle off to its thermal over load. Clean the coil.

I recently purchased a used ac for my rv. it has two and one had gone out. the air coming out of the new one only gets down to 60 degrees while the air out of my old one is 50 degrees. they are both the...


No it means you 50 degree one is working better than perfect. Clean the one that is only getting down to 60 degrees but remember if a unit is dropping the air temp by 20 degrees its working fine. You ck this by cking the air at the intake where the filter is say temp is 80 degrees and then take a reading at a discharge vent where the cold air comes out if its 60 you have a 20 degree drop and that is considered good. If the unit was low on freon the unit will freeze up (ice will form on the inside coil).

Ac leak at coil durango 1998 how much for repair is typical


I had a 1999 Dodge Durango with the 4.7L V8 and actually sued Chrysler/Dodge and the 3 dealerships under the Magnuson-Fergey(spelling?) act for breach of warranty repair. I had spent over $4500 over the course of 3 summers attempting to resolve the problem. We replaced the pressure release valve, condenser, coil, lines, blower etc. I was convinced it was a lemon or the aftermarket TV had damaged the roof AC.
It turned out to be the pressure release valve (#2) had broken at installation. Ironically this was the very first part replaced under warranty, and the replacement unit was defective or improperly installed.
The problem really only surfaced when it was over 95 degrees F. It would cool it down some, but not the 47 degrees according to specs at the vent.
After Town Motors in Exton PA finally resolved it, I ran it for 3 more years before selling it to little brother. He still runs the wheels off it, an otherwise good truck.
I still miss that V8...ahhh memories.

start with making sure you have aclean filter, after that make sure the blower speed is at the proper setting when the air conditioning is on---usually either high or medium high for a fixed speed system, make sure the return air vents are not blocked or restricted as well as the delivery vents not close or restricted to cause too much static pressure ( back pressure at the delivery side can reduce air flow across the a-coil ) also make sure the insulation sheet that is usually above the a-coil is not being blown down across the a-coil entryside when the blower is on. After checking all these, if you find nothing you should start by having the pressure checked --- basically comparing the pressure at the "outside unit" to the pressure at the "inside unit" or a-coil. these are high side and low side pressures. Have you done anything else to the house----attic vents, new soffits, insulation, etc that may be affecting heat gain in the house.Is it a house, mobile home or what?

Air Handler Blower


if you have a meat thermometer, place it in the vent when the air is on, it should be cooling somewhere around 15-18 degrees F lower than what actually temp is, so if its 84 degrees, your unit should blow around 67 degree air out of the vent. if it is not call a tech. your system could be under or over charged.

The thermostat is set at 73... the air conditioner is running and cold air is blowing but the house is currently 82 degrees. I've checked the unit outside and there is no icing. I don't know what to do.


check to see supply air should be around 58F. 20* difference form supply air to return air if 58F my guess unit under sized air filter clean? when was the last time you had the unit tuned up?

Blower motor location and installation on 73 ford gran torino


It's less than foot from the heater core. I would guess that either the damper doors are not on correctly or the vent hoses are not hooked up. Can you hear the blower motor running? Maybe they didn't hook the motor back up when they replaced the heater core. It takes a ground and a hot wire.I can't remember where it's at but it may be part of the same unit. Did you check the fuse?

Cooling Problems


Your filter is clogged. Not the one at the bottom of the unit.The one above the unit. It is like a raditor coils, kind of a bear to get to. We have cats and dogs the filter gets most of the hair but not all.Usualy about 6 bolts to take out.The proublem will be at the bottom of the top filter.
