If your air conditioner was manufactured after 2010, it uses the new style of refrigerant R410A.
Air conditioners made prior to this most likely are filled with R22.
Why Are There Different Refrigerants?
Believe it or not, R22 has actually been in the process of being phased out since the mid 1990s and was completely phased out as of January 1, 2020.
R22 refrigerant is not nearly as eco-friendly as the R410A refrigerant.
R410A offers several benefits compared to R22:
Better Performance – The R22 refrigerant has to work harder to let go of the heat it absorbs inside your home. This extra work means your compressor has to work harder in return leading to a decreased lifespan.
Better Efficiency – As previously stated, R410A is more capable of absorbing the heat from your home and dispersing it outside. This increases the overall efficiency of your air conditioner and allows your home to cool more quickly.
Cheaper – R410A is much cheaper to obtain than R22. As R22 becomes more and more scarce, the price of it will continue to rise. Eventually all supplies of R22 will be depleted and you will have no choice but to replace your air conditioner if you have a refrigerant leak.
Better For Environment – The entire reason for the R22 phase out is its damaging effects on the earth’s ozone layer. R410A is a much more eco-friendly refrigerant.
Can You Mix R22 and R410A?
This is absolute NO.
If you attempt to mix the new R410A refrigerant with your R22 air conditioner, you will destroy the compressor of your air conditioner.
R410A requires much more pressure to do it’s job compared to R22.
It should also be said that there is no way to convert an R22 air conditioner to an R410A unit.

A five star review does not begin to explain the experience we had today. To start the first gentleman to come diagnose the air conditioning issue we were having was down to earth and most importantly honest. He gave different options as well as his opinion. After weighing pros and cons we went with the complete new unit. They came out on the day and time as promised. They introduced themselves and we walked them to the basement and they quickly got to work. They wore booties on their shoes (not at our request, but rather a courtesy) acknowledged my children and dogs which is huge to me then went over everything as they were removing and installing. Cleaned up like they were never here, set everything up for us and made sure it was working properly as designed. Huge shout out to SHC and will 100% be recommending to neighbors.
Adding on to my initial review of Sears from my experience last year since it does not appear Google allows me to just add a new review. I will keep this one short since it just reinforces the previous 5-star review I left. Again had an A/C problem after hours (this time a Sunday evening, 6:00ish or so). Called Sears and had the on-call tech paged. He called back so quickly, I almost didn't answer b/c I didn't recognize the number and it didn't click that I would get a call back so fast. Did not go with the after hours call out, but was set up with an appointment the next day. Joel T. was sent out and did a great job in diagnosing the issue. Unfortunately, the issue is not worth repairing b/c of the cost vs age of the unit; however, it can limp along for a little while longer while I thoroughly weigh my replacement options. Joel provided replacement estimates at a few different cost points, understood my need to call around for multiple estimates before deciding, and even called back later in the day to advise the office located one other lower cost option he previously thought was not available. Through all of this, Joel presented everything matter of fact - it was not a high-pressure sale pitch, proclamations of doom and gloom if I didn't commit to replacing right away, etc. Just good conversation about my options through Sears.Last night around 9:45 I realized my A/C was not working. Neighbor recommended Sears Heating and Cooling (not Sears and Roebuck, she made sure to mention). I called and spoke with a very nice lady who advised the on call tech was only on call until 10:00 and offered to page him for me. I was not sure if I wanted to have the tech paged so close to quittin' time, but she assured me it would not be a problem. So, the page went out around 9:57, and I got a call back at 10:00. We discussed the issue and the offer was made to come out in that night, but I declined. The on call tech entered my information and said the office would give me a call between 8 and 10 in the morning to schedule something. At about 8:05 the office called and said someone would be out between noon and 6. Turns out, the tech (Austin) finished up a nearby job around 10:45 and was at my house by 11:00. He quickly diagnosed the problem, presented the repair options, and helped walk me through deciding the route to take. While he advised there were several levels of repair options, he went over the lowest cost one and the next level up with a better replacement part and warranty only. He felt given the age of the unit and the cost after the 2nd repair option, it made no sense to discuss the higher cost options because they just were not worth it.Long story short, Sears Heating and Cooling was very courteous, professional, helpful and better than on time. I am thankful for the neighbor's recommendation and understand why she has used Sears for 20 years. I asked Austin about the service club and he provided very good information about it, presented a valid points on why it is a good idea and recommended I call the office to discuss further if I had more questions. He did not try to push it on the spot, which was appreciated. I have seen other reviews about the cost of Sears, but I have also seen the response that they strive to be competitive, not the most expensive - not the cheapest, but the best value. This is a strategy I agree with, it is not always about being the cheapest...it's about providing the best bang for the buck, and Sear accomplished that for me today. Prompt service, reasonable cost, and most importantly, I am sitting in a cool living room on a hot, humid evening.
