It's possible to add together Freon to your air conditioner unit yourself, but you'll need some general knowledge about ACs and a few specific tools to do it correctly. The process can exist dangerous, so hire a qualified professional person if yous feel unsure about what to exercise. Start past diagnosing the problem to make certain depression refrigerant is the issue. Once confirmed, then brand sure the inside of the air conditioner is clean earlier yous begin. You'll demand a refrigerant gauge set with 3 valves and a canister of R-22 or R410A refrigerant to proceed.

1. one

   Bank check for vents bravado warm or room temperature air. This is a tell-tale sign that your unit needs a refill of refrigerant. Still, a broken thermostat may cause the aforementioned trouble. If it's a refrigerant upshot, the air temperature will steadily abound warmer over time because your unit of measurement is slowly losing refrigerant.^[1]

   • If a broken thermostat or other issue is causing the warm air, the temperature of the air will probably fasten or fluctuate.

2. two

   Look for ice on the coils. Peek through the forepart window of the AC unit of measurement to audit the pipes inside. If the pipes and coils look frosty or ice-covered, this means you're experiencing a leak and slowly losing refrigerant. The leak needs to exist repaired by a qualified HVAC technician or you'll go along to experience the same problem.^[2]

   • Adding refrigerant without fixing the leak may further damage your AC unit.

3. 3

   Expect for water accumulation on the floor nearly your furnace. Inspect the area effectually your furnace. If you lot see water pooling effectually it, this indicates condensation. Your coils were most likely icy, and now the ice has melted around the furnace area.^[3]

   • The h2o can harm your furnace and chemical compound your problems, and so information technology'southward best to accept a qualified HVAC technician come out to audit the issue.^[four]

4. four

   Accept a qualified HVAC technician repair any leaks. Ac units are sealed tightly and the Freon should never leak. If you need to refill refrigerant, you probably have a leak. You lot will continue to experience the same problems until the leak is addressed.^[5]

   • Adding more refrigerant is a quick fix, only eventually this will damage your unit of measurement.

1. 1

   Schedule or perform routine maintenance before adding more Freon. Your Air conditioning'south air filter, blower bike, evaporator whorl, and condenser roll need to exist cleaned before you "charge" your unit with more refrigerant. Adding more refrigerant to a unit with dingy parts can damage the Air-conditioning.^[6]

2. 2

   Choose the correct refrigerant for your unit of measurement. Putting the wrong refrigerant in your unit tin can cause combustion, injury, and belongings damage. Check your AC manufacturer'south operating guide to find out which refrigerant your unit needs. If you lot don't have the operating guide, check the electrical control box or the unit of measurement'southward chiffonier for the information. The 2 virtually mutual refrigerants are R-22 and R410A.

   • R-22 is more often than not used in older units and is slowly being phased out considering it is an ozone depleting cloth.^[7]
   • If your AC is leaking R-22, it'south important that you get the problem stock-still every bit before long as possible. Since R-22 is in the process of being discontinued, the toll for it has skyrocketed and will just continue to become higher.^[8]

3. 3

   Protect your eyes, pare, and lungs when working with refrigerant. Wear safe goggles and thick gloves when handling Freon. Never directly inhale any refrigerant; doing so tin can atomic number 82 to sudden death. Some refrigerants are particularly hazardous and crave respiratory protection -- read the packaging for more information.

   • If you get Freon on your skin, rinse the expanse with h2o and seek medical treatment immediately.
   • R-717 and R-764 refrigerants are extremely irritating to the eyes and lungs. R-717 is flammable. Handle with caution.

4. iv

   Make sure the outside temperature is above 55°F (12.vii°C) before proceeding. Liquid Freon will automatically seek the coldest surface area of an enclosed Air conditioning unit of measurement between the furnace coil and the outside condensing unit. When outdoor temperatures are under 55°F, the coldest area of your organisation volition most likely be the outside unit. The Freon will not carry properly in these conditions.^[9]

1. 1

   Consider having a professional perform this process. Information technology is highly recommended that a qualified professional refill and recharge your Air-conditioning unit of measurement. The process itself is dangerous, and if done incorrectly, you can damage your unit. Homeowners are permitted to add together refrigerant in the U.S., but the Environmental Protection Bureau (EPA) requires that anyone you rent to do the task have a professional certification.^[x]

   • Proceed with caution if you decide to do this yourself. Improper treatment of refrigerant can cause injury, death, explosions, and property damage.

2. two

   Turn off your AC unit at the thermostat and breaker. Go to the thermostat that operates your air conditioner. Turn it to the "off" position. Your unit will either have a fused disconnect or circuit billow attached to it. If your unit has fuses, disconnect them. If your unit has a excursion breaker, turn the billow off.

3. 3

   Claw up the refrigerant gauges to the valve connections. There are 3 valve connections fastened to your unit'southward hardware, with a valve on each side (left and right). Attach the gauge with the bluish hose to the low-pressure valve on the left side. Attach the gauge with the reddish hose to the high-pressure valve on the right side.^[11]

   • Leave the centre valve open up for now; that is where you'll connect the yellow hose to feed the refrigerant into the organisation.

4. four

   Turn the Ac unit back on and wait about fifteen minutes. Later you turn the AC back on, the unit of measurement volition need to run for several minutes and so that it can stabilize itself. You won't become an accurate reading on the refrigerant gauges until the Ac has stabilised.

5. five

   Open up the canister of refrigerant by twisting the spout on the bottom. Attach the yellow hose to the refrigerant canister's valve and adhere the other cease to the center valve connection on your gauge. There will exist a small knob on the lesser of the refrigerant canister. Twist it several times to open the refrigerant.^[12]

   • The heart valve is the ane between the blue and red valve connections.

6. half dozen

   Open the blueish depression-pressure valve on the left side. Open it for a few seconds, then shut it. Open up it for a few more seconds, then close it again. Go along doing this. Y'all desire to slowly allow small amounts of the refrigerant into the unit at a time until you lot achieve your target subcooling temperature.

7. seven

   Picket the guess until you accomplish the target subcooling temperature. The target subcooling temperature is stated on the outdoor unit rating plate. Use the gauge to monitor the temperature then y'all know when to close the valve.^[xiii]

   • For instance, the rating plate might say something similar "x degree TXV sub-cooling."

8. viii

   Turn off the valve and disconnect the guess set. In one case the target subcooling temperature is reached, turn the valve all the fashion off. Twist the knob on the refrigerant canister to stop refrigerant from going into the hose. Disconnect all of the hoses and the guess set from the Air conditioning unit.^[14]

   • Since the unit is running during this process, there's no demand to restart your unit of measurement subsequently adding refrigerant.

9. 9

   Perform an electronic leak test to ensure condom operation. You tin buy an electronic leak detector at most abode comeback stores and online. Each detector is slightly different, simply in general you just demand to run the tool along the refrigeration components to browse for a leak.^[15]

   • If you don't feel qualified to do this yourself, have a certified HVAC technician come up out to examination the unit for you.
