Question about Heating & Cooling

1 Answer

The factory charge is 195 oz. seams kind of high for a residential heatpump to me. i'm used to a unit holding approx 5-6 lbs. this is a 410a system.

    So you think someone on here knows better than the engineers who designed your equipment for the manufacturer? Does it work?

    In order to get the efficency there is more coil both places and more piping required for heat pump in outside unit.

410a system is a higher efficiency unit that has a larger outdoor coil and inside evaporator coil.also the copper line coming from outside are larger one size in diameter. thats almost 12 lbs. sounds like you have a 5 ton system

How much R22 should my unit hold when fully charged


If it has enough freon to freeze up then its not that low. Normally a 4-5 ton cooling only (non heatpump) will hold 7-9 lbs r-22 or 9-11 r-410a. Freezing can be caused by dirty air entering side of the coil also. Or slow blower

I have a goodman Model CKL 36-1K . It says Factory Charge oz R22 . Does that mean it uses R22 freon? The guy who sold it to me says it uses 410a and was only 2 or 3 years old. The serial # is 040637071 ....


Hello, the unit is a 3 ton and was built in 2004. 0z R22 stands for R-22 refrigerant. Not sure why he told you 410a but if the unit says R-22 than that must be used.

How many bottles of refrigerant a volvo s80 takes?


That's a REAL GOOD question! The factory refrigerant charge specifications for your vehicle is 2.20 Lbs. of R-134A. Freon R-134A comes in 12 oz, 14 oz, 16 oz, 19 oz, and 22 oz cans (as well as 30 Lb Cylinders) - it depends on which brand/size can you are buying, whether your system is COMPLETLY out of freon, or whether it still has some freon in it.

The best way to deal with the situation (in my opinion) if you are going to try and charge you own A/C system is to purchase a kit that comes with a gauge. A company called interdynamics has a real good kit available that comes with a reusable gauge. Once you have the gauge, all you have to purchase in the future is the freon itself. By using the gauge, you can more accurately charge your system without the worry of possibly overcharging. (Overcharging can cause extremely high pressures that can do serious damage to your vehicle or cause personal injury.)

Anyway, this kit is available at O'Reilly's as well as other auto parts retailers. Here is a direct link to see the kit at O'reill'ys web site.

There is also a whole bunch of instructional videos on how to charge your system at the interdynamics web site. CLICK HERE

Does anyone know how many cans of freeon it takes to charge the air conditioner


It depends on what size cans of freon you are getting and if the system has been retrofitted for R-134A refrigerant (1992 came originally equipped with an R-12 system). The factory specifications call for 1.8 Lbs. of R-12. If it has been retrofitted for R-134A, the general "rule-of-thumb" is 85% of the R-12 specification is needed to charge the system with R-134A. So if we do the math: 1.8 Lbs (R-12) X .85 (R-134A) = 1.53 Lbs. R-134A needed for a full recharge (providing the system is COMPLETELY empty. Then you will have to find out how much is in each can that you plan to buy and do the math to figure out how many cans you need. (some have 12 oz., some have 14 oz., some have 16 oz., some have 19 oz. and some have 22 oz.)

    Where do I add the new r 410a refridgerant on 2004 Pontiac vibe?


    410a cannot be used in a automotive system it will cause damage to your compressor, other other a/c components.
    410a is used for home use only.as a substitute for R-22
    see below definition.


    Although the United States Environmental Protection Agency has mandated that R-22 along with other hydrochlorofluorocarbons (HCFCs) be phased-out in the United States, few window-mounted air conditioners are available that use R-410A. However, all of the largest central air conditioning systems manufacturers in the United States offer R-410A. As an alternative to window-mounted systems, a ductless "split" system is available which uses R-410A refrigerant, and can be installed with a 3-inch hole through the wall (or window opening).[4] R-410A has replaced R-22 as the preferred refrigerant for use in residential and commercial air conditioners in Japan and Europe.
    Parts designed specifically for R-410A must be used as R-410A operates at higher pressures[5] than other refrigerants. Thus R-410A systems require service personnel to use different tools, equipment, safety standards and techniques.[6] Equipment manufacturers are aware of these changes and require the certification of professionals installing R-410A systems. In addition the AC&R Safety Coalition has been created to help educate professionals about R-41-A system.
    manufactures recommendations for vehicle

    NOTE:
    • R-134a is the only approved refrigerant for use in this vehicle. The use of any other refrigerant may result in poor system performance or component failure.
    • To avoid system damage use only R-134a dedicated tools when servicing the A/C system.
    • Use only Polyalkylene Glycol Synthetic Refrigerant Oil (PAG) for internal circulation through the R-134a A/C system and only 525 viscosity mineral oil on fitting threads and O-rings. If lubricants other than those specified are used, compressor failure and/or fitting seizure may result.
    • R-12 refrigerant and R-134a refrigerant must never be mixed, even in the smallest of amounts, as they are incompatible with each other. If the refrigerants are mixed, compressor failure is likely to occur. Refer to the manufacturer instructions included with the service equipment before servicing.

    Chargeing Unit


    The old 410A fittings are different than the r-22 fittings. There are adapters available on ebay. Remember 410A runs at higher pressures than 22. Be sure to use gauges for 410A! Use the right gauges with the right hoses! High pressure.. Use the right gauges and the right hoses!

    What should the pressure readings be for a American Standard Freedom 500 2.5 ton air conditioner be


    Hi, this depends on the outdoor air temperature and type of freon this unit has. The hotter it is outdoors, the higher the pressure will be as they use a pressure/temperature relationship. If the unit is R-22 and lets say it is 90* F. out side, the low side or suction side will be at around 68 to 72 p.s.i which would give you an evaporator temperature of 40* F. Head pressure would be at around 90* plus 27*= 245p.s.i. This is if the condenser fan is in good condition and the outdoor coil is clean. If you are using a set of manifold gauges you have the pressure/temperature scale right on it. If the unit has a TXV for metering, you would need to charge it using the subcooling method. On a Non-TXV you would use the superheat method. If you are using the new R-410a freon, the pressure are extremely high in these systems compared to the R-22 system, so make sure you look at the units data plate to read the type of freon. The color of the container is green for R-22 and a Pink for R-410a and the 410 a unit will display a pink warning sticker on the unit to tell you. The pressures on the R-410 would be at 90* F, low or suction side at that temp is around 125 p.s.i., and around 400 to 420 p.s.i. on the high side, much higher then the R-22. You would also need a manifold gauge set made just for the R-410a (AZ-20) as of the extreme pressures in the system. There is never a set pressure to go by as the outdoor temperature will raise and lower the pressure of freon very fast. If you are asking this question because you have a manifold set and are taking a reading, the unit has a charging method pasted right on it from the factory showing what pressure they want it to run at. Your gauges also can be used as a pressure temperature chart, or you can pick one up free of cost at a a/c parts house to keep with you. It will show you how to calculate the charge for your unit. If you are familar with pressures, this should be of a great help to you. I hope that I have helped you on getting the unit charged properly. Please keep me in mind when rating me, as I know you will be kind. Just drop by a wholesale a/c parts house, walk in and ask for a pressure temperature chart, and they will hand you a couple of them. They have very good information and no how on all of the most common freons in use today.
    Best of luck

    Carrier 38yca030370,with copeland compressor M#cr28k6-pvf-270, i need to know what refrigerant it uses. thanks


    How old of a unit is it? Chances are it is R-22. If it is newer than last year it may be R-410a. The unit should indicate what type, and charge (lbs/oz) on the nameplate of the outdoor condensing unit. Hope this helps.

    In a residential system that presently has a 3/8 -5/8'' lineset 30 ft long on a R22 system, can a 2.5 ton 410A system work on that size lineset?


    Look at the manufacturer's instructions and it will tell you how much line set the factory charge is good for. Don't plan on using the same line set that was hooked to the R22 unit as R22 and R410a use different types of oil that are not compatible. Hope this helps.
