Sounds like you have a possible obstruction in the lines and/or do not have the proper amount of refridgerant in the system. Check the site glass to see if you see air bubbles, if so, it could be that more freon is needed, if no bubbles and no liquid refridgerant is seen, you likely have an obstruction in the system.

It is recommended that the system be subjected to a vaccum before recharging with refridgerant, to make sure that the system is clean and clear of any obstructions. It is also best to install a new refridgerant filter with any installation to help mitigate contamination.

If you have a proper set of gauges and the specs for the system, a competent HVAC tech should be able to determine the problem and a probable solution.

Why does my ac not blow cold air?


You have to try resetting the system. First turn the breaker off for the condenser and wait about 20 seconds After you turn it back on the system should reset. If you need any other assistance check us out online at Boca AC Service we are always happy to lend a helping hand

Why would a 2006 Nissan Altima blowing hot air from the air conditioning system?


Look at the front of you A/C compressor with your A/C sent to max. the front of it should be moving with the rest of the pulley, if not you most likely have a leak and it's out of freon. If it's moving and still no cool are careful touch the pipes coming from the compressor, one is you hi side and the other low side. The smaller one (hi) should be warm or hot... the other (low) should be cold and sweating. If the clutch on the compressor is moving and those lines aren't hot and cold then your low on freon.

I have a breez aire wkce 1060 r134a.. what should the low side pressure be at/


the low side pressure is defend on the size of your ref.but if it is use in home appliance not in commercial it its range 12 psi more or less but yuo consider the cooling temp. of your suction line but if it look sweating it means your suction pressure is ok if not add refrigerant charge until it sweat.

What is the a/c charging pressure on roof top r/v units?


The easiest way to charge a unit is to add freon to the low side until the line sweats and the coil is sweating top to bottom. The pressure depends on the wet bulb temp on the low side line the ambient temp outside and the intake temp inside the
RV. A good unit will start to sweat between 50 to 78 pounds on the low side. good luck

I need to know the correct high/low freon setting on an Inter-Therm 2.5 ton central unit with a Split System using R-22 @ 90 degree outside temp. Thanks


Listen the easiest way is to add freon on the low side until the line starts sweating. This is the quickest way to do it. The other way you have to know your wet bulb temp on the low side line the outside temp the inside temp at the intake and the ambient temp outside this is complicated and works no better than the sweat method i described.

I have water running from under the passenger side interior floor board what could it be coming from or has any one else experienced it really flows when turning corners


It sounds like condensed water from the air conditioner. Just like a glass with ice in it sweats, the cold part of an air conditioner sweats. That water needs to go somewhere. There is a drain on the bottom of the ductwork that comes out under the car, often toward the passenger side.

If the drain gets plugged, the A/C still sweats, but the water builds up inside the ductwork.

You can often clear the drain by blowing some air up the drain from the outside. (Don't use too much pressure!)

Just blowing air not cooling, outside unit doesn't seem to be working but inside just blowing air


First off, check power:disconnect box outside may have fuses,then check power at fuse box.If you have power(220 volts) then check for 24 volts at T-stat line.Also, make sure T-stat is set to A.C.With power on go outside and listen to condenser unit.If fan is rotating listen for humming .If it is not running, it could be a bad contactor or a bad or capacitor .If it is running check after 5+ minutes if warm air is coming out of the outside unit.Also, wash the condenser unit:start by spraying the hose about 45 degrees downward ,going side to side,and down on all sides.Do Not use High pressure hoses,it will bend coil fins.After it runs for about an hour,or so, go out and see if low pressure line(big one) is sweating and cool, and high pressure line (small line) is warm.

Ac capillary tubes


Sounds like you have a clogged cap tube. Yes they should both be sweating, I would expect your low side pressure to be lower though unless it is real hot in the camper. You can replace the tube but make sure what goes in is the same diameter and length because that is all engineered for proper metering into the evaporator.

Window Air Conditioner Sweats


You need to seal the portion of the air conditioner that is inside the window from the portion that is outside the window, Sweating is caused by moist outside air leaking in and contacting the cold portion of the air conditioner. Do not use duct tape, buy aluminum tape which is what professionals use to seal air leaks on ducts. Home Depot sells the tape. Buy the smallest quantity you can find that will do the job ( it can be expensive ) unless you plan to go into air conditioning duct installation.

For best results use some form of insulation over the accordian like side baffles ( cut to fit) . Styrafoam from packaging or silver backed insulboard (Home Depot). Now tape the sides of the insulation to all sides of the window frame, bottom of the window, the sill, and the air conditioner.

Unless you enjoy doing this every year - plan on this being a permanent installation. It is a tedious job because the aluminum tape is not very forgiving and has a peel off backing but it sticks forever.
