Are Ac Compressors Interchangeable?

Are all AC compressors the same?

Although the basic concepts behind the chilling cycle remain the same, an AC compressor is not the same as a refrigeration compressor. They use similar components and some may even have a familiar system architecture, but they also vary in some essential ways.

Can I swap AC compressor?

The compressor is an expensive item to replace. Because dead compressors usually happen in old air conditioners, it’s more cost-effective to start over with a new AC rather than pay to put a new compressor into a system that’s already wasting power and a few years from the junk heap.

Can I use a different brand compressor?

Compressors are generally designed to be used with a specific refrigerant or group of refrigerants, so make sure there is a match between the refrigerant and the replacement compressor. Make sure the electrical characteristics of the replacement compressor match the original, including the voltage rating.

Does AC compressor size matter?

The size is very important because the correctly sized air conditioner should run a proper full cycle and ensure your home stays cooler longer. An over-sized AC system will quickly over-cool the air in your home and shut off too soon.

How do I choose an AC compressor?

To choose the right compressor for a refrigeration application, the capacity should be considered in relation to temperature and pressure levels. That is because the volume occupied by refrigerant vapor molecules varies according to the temperatures and pressures within the system.

How much does it cost to replace a compressor in an air conditioner?

The average home air conditioner compressor costs $1,000 to $2,500 to replace. A new AC unit compressor costs $400 to $1,300. The labor cost to replace a home AC compressor is $600 to $1,200. HVAC contractors charge $100 to $150 per hour plus parts to repair an AC compressor.

When replacing AC compressor what else should be replaced?

For the compressor that is seized, you will at the very least need to replace the compressor assembly and clutch, receiver drier, expansion valve, and flush out the system. I recommend having a mechanic diagnose your vehicle to see if any other components need replaced in order to fix your air conditioner.

Do you have to evacuate AC system to change compressor?

To remove the lines from your AC compressor you should first have the system safely evacuated of refrigerant. Once the system is empty, removing the lines is as simple as removing a few bolts. With the lines off, you can move onto removing the compressor so you can replace it.

Can I replace my AC condenser myself?

Simply put, no, you cannot replace your AC unit yourself.

Can you mix and match AC units?

If you combine a condensing unit with an air handler (or furnace) it wasn’t designed to work with, in the best case the result will be reduced operating efficiency. In the worst case, the mismatched system may not work at all. Or, it may appear to run initially and then fail after a short time.

Are AC condensers interchangeable?

The condenser you end up replacing it with will not be 100% compatible, which may cause it to suffer in both performance and efficiency. Repairs become more likely and more frequent as a result, and your monthly bills will take a hit.

Can I mix HVAC brands?

While it is recommended to buy the same brand for your HVAC systems, a furnace and an air conditioner manufactured by two different companies can usually still work together.

Is it better to undersize or oversize AC?

While an AC’s capacity typically matches its energy usage, an undersized air conditioner will use more power simply because it is likely to run continuously, barely stopping for breath.

What size AC compressor do I need?

Rule of Thumb — The maximum size unit you should buy would be 15% over the BTUs you need for cooling and 40% of the BTUs for heating.

What happens if your AC is too big?

If your air conditioner is too big, you’ll have hot spots – or inconsistent cooling – throughout your home. Hot spots occur most often when cold air doesn’t disperse through the home efficiently enough. You’ll notice that some of your rooms are cool and comfortable, while others are hot and humid.
