If it is not working accurately, your AC will not have the ability to cool your house successfully. On this article, we’ll discover find out how to establish a damaged compressor and supply ideas for troubleshooting and restore.
Probably the most widespread indicators of a failing compressor is a scarcity of cooling. In case your AC is working however not blowing chilly air, it could possibly be as a result of the compressor is just not compressing the refrigerant correctly. This may be brought on by a wide range of points, together with refrigerant leaks, electrical issues, or mechanical failure. One other symptom of a foul compressor is a wierd noise coming from the out of doors unit. The compressor is a transferring half, so it is regular for it to make some noise. Nevertheless, should you hear a loud grinding, squealing, or rattling noise, it could possibly be an indication that the compressor is failing.
In the event you suspect that your compressor could also be defective, it is essential to name a certified HVAC technician for analysis and restore. Trying to repair a compressor your self might be harmful and will void your guarantee. A technician will have the ability to check the compressor and decide if it must be changed. In some instances, the compressor might be able to be repaired, however in different instances, substitute could also be obligatory. In case your compressor is failing, it is essential to have it repaired or changed as quickly as potential to keep away from additional harm to your AC unit.
Figuring out the Sound of a Working Compressor
The compressor is an important element of any air con system. It’s chargeable for compressing refrigerant fuel and sending it by means of the remainder of the system. A working compressor will usually make a buzzing or buzzing sound. This sound is normally louder when the compressor is first beginning up, but it surely ought to steadily grow to be quieter because the compressor reaches its working pace.
If the compressor is making an uncommon noise, it could possibly be an indication that there’s a drawback. Listed below are a few of the commonest noises {that a} compressor could make and what they may imply:
| Noise | Doable Trigger |
|---|---|
| Buzzing or buzzing | Regular operation |
| Clicking | Free or broken compressor |
| Whirring | Worn bearings |
| Screaming | Broken compressor |
In the event you hear any of those noises, you will need to have your air con system inspected by a certified technician. A technician can diagnose the issue and make the mandatory repairs.

5. Decoding the Readings
Desk 1: Typical Compressor Present Draw
| Compressor Measurement | Present Draw (Amps) |
|---|---|
| 1-Ton | 4-8 |
| 1.5-Ton | 7-10 |
| 2-Ton | 9-12 |
| 2.5-Ton | 11-14 |
| 3-Ton | 13-16 |
Examine the measured present draw to those typical values. A considerably decrease present draw might point out a defective compressor, whereas the next draw might recommend an issue with {the electrical} circuit.
Measuring Compressor Temperature
A compressor that’s too sizzling or too chilly can point out an issue. To measure the compressor temperature, you will want a temperature gun.
Level the laser on the temperature gun within the middle of the compressor. Press the set off and maintain it till the temperature studying stabilizes. Document the temperature.
The traditional working temperature vary for a compressor is between 150-250°F (65-121°C). If the compressor temperature is exterior of this vary, you will need to have the compressor inspected by a certified technician.
The next desk supplies a normal guideline for deciphering compressor temperatures:
| Compressor Temperature | Doable Trigger |
