A/C Compressor Stolen
 
I have the exact part number but I was wondering if I could order another r-22 unit with a higher seer or with a heat pump?

I'm not really familiar with ac units but I figured if I could order a compressor that was better now it would help me in the long run.

You can still purchase a "dry ship" unit, which is a unit built to use R-22 that is shipped with none in it. After installing you would evacuate the system and recharge with virgin R22. I don't believe you'll find anything other than a 13 SEER in the dry ship lines, although I don't really know.

If your coil is capable of handling a heat pump you could install a heat pump. You'd have to change the thermostat and wiring to accomodate this sort of setup, which can be a big job for a DIYer.

Before you order anything make sure to know the correct terminology. A compressor is just the device that pumps the refrigerant. A condensing unit would be the whole outside part. Always best to replace the indoor coil and condensing unit at the same time so they are a matched set.

Just a FYI...R22 prices are 4 times what they were just a couple years ago due to it being phased out. In a few years it will no longer be imported or manufactured in the US so there will likely be several more large price increases. IMO it's time to move into a 410A system and leave the R22 alone.

Thanks for the information.

My friends dad looked at my system and said that the coil needed to be replaced. He said I would need a 4 ton slab coil as well as the condensor.

One question....does a air handler contain the coil or is that something that needs to be purchased also?

I found a package for a Rheem system that has a 14.5 seer condensor and a air handler.....would I need a coil as well? I'm switching to r-410a since I have to replace everything now.

There are coils at each end.

The way the unit works is that the compressor compresses the gases, which drives up the heat under pressure. That pressurized gas is fed through the condenser coil outside, which lets it dump waste heat into the air, cooling the still-compressed gases. Those gases feed through the tubing into the air handler unit, where they pass through some form of expansion valve (which limits the flow, sort of similar to a garden hose nozzle) and in to the evaporator coil. As the pressure in the gases drops, the temperature of the gas falls (further reading:Ideal Gas Law) and as ambient air is blown across the cold evaporator coil, the air loses heat to the cold coil as it attempts to equalize the temperature. That cooled air is then ducted through the house. The now-somewhat-warmed gases flow back to the compressor to repeat the process.

Sorry if I misunderstood but do I need to order a separate coil if I'm getting a air handler? His dad said that I needed a condensor and coil but the condensor and air handler are cheaper....didn't know if I'm getting more with the condensor/handler package or if I still would need the coil.

I do appreciate the info though...I like to know how things work.

Air handlers have the coil already installed.,

Well I just talked to him and he told me to just get a 4-ton slab coil.......Rheem doesn't seem to make one of those.

Would this work?

I assume since it says multi-position that it would work and space isn't an issue.
