04 envoy iddles up and down with the air conditioner on?
you might have a hole in your vacuume hose
Answer . Hey Mike==As a rule of thumb with the temp and blower speed set on high, it is great if the air comming out of the vents is 40 deg lower than the ambient temp. ie. If it is 100 deg outside the temp of the air should be 60 deg. It varies with humidity, makes and individual a/c's. Good…luckJoe. (MORE)
Answer . \nIf you are talking about the larger of the 2 copper lines, the problem could be that the unit is low on refrigerant. \n. \nCheck to ensure that the large line is insulated and not exposed.
There are a couple of things that cause your AC to freeze up. If your indoor coil is icing up you: 1. Have a dirty filter 2. Have a system low on refrigerant 3. You have a blower that is not providing enough air across the coil 4. You have set the thermostat too low (below 70 degrees Fahrenheit,… setting the AC lower does NOT cool the room down faster) (MORE)
Answer . Colder air is more dense than the warmer air. Warm air will tend to go up and the colder air will tend to go down. To get the upstairs to cool down, you may need to adjust the heat registers, closing or partially closing some of the downstairs registers. Sometimes it just takes a little… more effort to move the cool air upstairs, and you may need to get a larger air fan on your ac unit. (MORE)
Answer . No, but it's a good idea to protect any metal equipment from extreme weather.
Answer . \nMost 2 probable answers are the filter or coil the filter is suppose to keep clean is dirty - shine a light in the coil and see.\n(2) It is low on refrigerant and has a leak.\n. \nThere are other conditions but I am assuming you are hot and the outside temp is also.
Answer . air conditioning compressors put a load on the engine causing it to slow down, vehicles have an idle compensator which when the air conditioning is on speeds the engine back up to normal idle speed or" compensates" for the added load.
AC drain line for Envoy . The drain hose is located to the left of the engine compartment just below the AC lines coming out of the firewall. There is a rubber tube about 1" diameter and it has a small plastic tube coming out from the bottom side of the larger tube. This sometimes gets blocked an…d causes leaking onto the rug area inside the truck, just pull the larger tube out and clean the small/large tube. If there is any water from the AC it will drain out..

You Just instslled a new air conditioner compressor but your air conditioner still does not blow cool air you were told by a mechanic that it has to be reset How do you reset it it is a 2002 GMC Envoy?
Answer . If system was opened to the atmosphere it will have to be evacuated prior to charging
Answer . You're not getting enough air across the evaporation coil. You'll need to either install a larger fan or replace your filter.
Answer . This is probably related to a dirty throttle body. In order to clean it properly you must disconnect the battery and remove it. Not very difficult to do but it will make a big difference in the idle smoothness and fix the stalling. The PCM will reset after you disconnect the battery for …15-20 min and take a few drive cycles to re-learn everything. I am about to do mine within the next few weeks as the winter gas always causes problems for me. (MORE)
its hidden under black plastic cover, three srews holding it down. its on top of windshield washer tank. so look for the fill cap for ww. pasanger side and might have a brace you need to remove to lift off cover.
A central air conditioner is different from a window or wall unit in that it cools the whole house or business. The most common reason for ice to be forming on the air conditioner is that the filters are clogged. In an air conditioner for your home, the filter is the same one as the burner for your …heat. I change mine on the 1st of the month. Twelve filters cost about $.50 each so for six to eight bucks you can save yourself the cost of a service call. Don't buy the pleated filters - they restrict too much air, causing ice buildups. (MORE)
Just change the dryer, and make sure the system has no leaks via a nitrogen test, and before it is filled with 134, you need to add oil for the specific change, in other words the oil will say for upgrade from r12 to 134. Add the correct amount then the 134 can be added.
The recharge valve for the air conditioner on a 2002 GMC Envoy canbe found by looking at the rear of the engine compartment. It willhave a cap over the valve labelled as low pressure side.
No, unless the airflow is so restricted that the heat builds up and triggers the thermal disc, which will shut down the furnace. The thermal disc is a safety switch that shuts the gas down so the unit will not over heat. About the filter, I change mine at a minimum of three times a year.
Heat rises, so placing the air conditioner high allows the unit to cool the hottest air that is at the top of the room.
Air conditioner is a perfect device that helps to control the home environment. As hot summer days are approaching, owing air conditioner is essential for any private housing. The initial purpose of air conditioner is to cool. Today, we are witnessing revolutionary changes in air conditioning system…s on the market.

you need to clean the throttle body...sounds crazy but it worked on my 04...everytime we would turn on the ac or defrost the engine would want to stall out,,,but if the floor heat was selected it would run fine....buy a can of throttle body cleaner and spay a rag with the cleaner and wipe down the b…utterfly on the throttle body DON"T SPRAY DIRECTLY INTO THROTTLE BODY!...MAKE IT AS CLEAN AS POSSIBLE...it'll take about 10 mins start to finish and you"ll be amazed that it worked.

An air conditioner uses refrigerant to transfer heat from one placeto another, such as from inside the home to the outside.
Set it to the room temperature you want (72* is good), If it does`nt make it there is something wrong and turning the thermostat up or down won`t fix it.
windows down- more drag. It would take more gas to keep the car moving because the windows would slow the car down.
I would say around $100 if they do not have a special going on. Figure 1 hour at their normal rate. That is of course if they don`t find anything wrong, then additional.
Hi Normally coils freeze up for 1 or 2 reasons : dirty coils and needs cleaned or low on refrigerant (Freon)
Assuming that all else is OK ---- go to Wal mart and buy a kit that includes the refrigerant and tools with complete instructions ---- I think mine was less than $30 a year ago. If you are a tinkerer it is not difficult. Or go to a auto AC shop and they will do it for you , checking for leaks et…c for around $90. (MORE)
Any refrigeration or AC evaporator coil has a tendency to ice up when they get cold. Water condenses on the coil when the air is cooled. That water can then freeze. If an AC system is operating correctly it will cool the air and eventually when room temperature reaches the set point the AC unit will… turn off, this give any ice that has formed on the evaporator coil a chance to melt. If the system is low on charge, the room may never reach the set temperature and therefore will not shut off. The ice will continue to build on the evaporator coil until it is completely iced over. A dirty evaporator coil can cause this as well, so change your filters often. Another possibility is the ac system has to be matched to room or house size. Too small and too large a system will both cause you problems. (MORE)
yeah, it could because the radiator is some what in between the a/c fan and the vents in your car. Check. follow your vents all the way back to ur fan, this is a very simple procedure
More than likely a vacuum leak. The vents are controlled by vacuum. When you go up hill it should downshift causing the rpms to raise. The manifold vacuum is lower the closer to wide open throttle, which causes enough of a difference to close your vents.
Is your filter dirty? is the fan in the air handler running when the outdoor unit is on? Your unit could also be low on charge.
assuming this is in your car, yes, you will use more gas with the a/c on than you would with it off.
There are several things that will cause the coil temperature to drop low enough to freeze the moisture. I always tell my customers to keep the setpoint at 70 or above just to be safe. There is no magic number. keeping the air filter clean and having a good refrigerant charge helps greatly.
8 out of 10 times it will freeze up cause it is low on refrigerant.
If you are talking about removing the freon in the a/c system then you will need a freon reclaimer.............
dirty coil , cloged filter, low freon ,clogg drain, stuck reversing vavlue or cloged condensation drain.
it depends i would say down because if you go up you turn the heat up. Most air conditioners as single speed. It's on or off. A residential A/C will usually provide a 15 degree temperature drop. 85 degree air returning will be 70 degree air out the register. The only way to get colder air out, woul…d to be to put colder air in. By leaving the system on, the air in your house will be lowered to the thermostat setting. If you have it set to 75 degrees, you can expect 60 degree air out the registers. (MORE)
The low pressure port of the A/C system usually has a blue or black dust cap and is located either on the larger diameter metal tubing typically found between the evaporator and compressor, on the compressor itself, or on the receiver drier (orifice tube systems only). The high pressure service port… is found either on the smaller diameter tubing or the compressor and is larger in diameter. Only charge through the low pressure port. There is a web site with a lot of help full information about your auto a/c system check out the link below.. (MORE)
Sure, Just like a refrigerator, an A/C has oil suspended in the refrigerant. as long as you set it right-side-up for 24 hours before trying to turn it on, the oil will settle out of the compressor head and be fine.
I would rate the financial status poor because there was no emergency funds saved for these kinda things.
it depends, if you leave it off for like 7 hours every day, yes it does, but if u turn it back on, ur actually spending more energy, plus, if u let ur home heat up, when u turn ur ac on again, its gonna use more energy to cool it down.
Theres two one is under the hood on drivers side and the 2nd one is under back seat on the drivers side
It can go up when hot air is filled and can come down by reducing the hot air.
Generally the thermostat setting is too low with the fan speed set at minimum or low, this results in the ac unit operating continuously and not cycling . The room ac unit may be undersized resulting in the ac cooling mode operating continuously so that the compressor does not cycle. Another reaso…n could be that the refrigerant charge is insufficient. Finally, as the ac is visual, therefore icing up will be noticed. A central ac unit is usually out of sight externally to the dwelling or mounted on the roof. (MORE)
The return hose or the cold line (different pipes) will both get very cold due to the operation of the Air Conditioner. This causes water to condense (condensation) on the portions that are cold, If the part is cold enough the water freezes into frost that you see.
The engine has to power the air conditioner pump, so less revs are made resulting in less revs for the alternator, resulting in less volts so your gauge drops a little
There are many possible issues with the most simple being you need to change out your filter/s and blow out your vents or you need a freon recharge, or it could be a more pricey fix such as a failing pump. It will take a professional check up to figure it out. It's easy to get one free or very reaso…nably priced. Just look in your local phone book & call around. Sometimes there's even coupon ads in their section! (MORE)
This is a pretty strange symptom, especially as air conditioning relies on the ram air effect from air moving across the condenser in order to exchange heat from the refrigerant to the ambient air. I'd check the condenser for leaves and other debris causing blockage of the fins, and I'd check to ens…ure that the fins are straight - if not, you can straighten them with a fin comb. Then I'd check to ensure that the sensor bulbs are attached securely where they need to be. If it's none of these things, you should have it taken in to a shop and have them do a system performance test. (MORE)
It is sufficiently cold outside (where the outdoor unit sits) that the coolant returned to the indoor unit is freezing condensed moisture from inside. The ice will build up and probably freeze the condensation pump an you may end up with a little flood on your hands.
The air conditioner is not in the Club. You need to get a fan to use on the club owner. Go left to the factory, and go up the elevator to fix the circuit box and restore the power. The factory worker will give you a powerful fan (you can fly with it, and do, later).
the compressor is places a drag on the engine,as a result it would generate more heat but the car should not be overheating. The fan motors should be on when the a/c is running.
The refrigerant absorbs heat from whatever area is being cooled, whether it be the passenger compartment of a vehicle or the interior of a building. The refrigerant is then pressurized and superheated. Once superheat is achieved, the heat from the refrigerant is rapidly exchanged with the ambient ai…r, and the refrigerant which is returned is much colder. A fan blows air over this cold refrigerant in the condenser, and the cold air flows through the vents to cool the area which is supposed to be cooled. That's a bit of a simplified version, but you should get the gist of it. (MORE)
