Is your AC blowing heat air as an alternative of cool, refreshing air? One potential offender is a defective compressor. The compressor is the guts of your AC unit, liable for circulating refrigerant and eradicating warmth from the air. If it is not working appropriately, your AC will not be capable to cool your private home successfully. On this article, we’ll discover the way to establish a damaged compressor and supply ideas for troubleshooting and restore.
One of the vital widespread indicators of a failing compressor is a scarcity of cooling. In case your AC is working however not blowing chilly air, it might be as a result of the compressor just isn’t compressing the refrigerant correctly. This may be brought on by quite a lot of points, together with refrigerant leaks, electrical issues, or mechanical failure. One other symptom of a nasty compressor is an odd noise coming from the out of doors unit. The compressor is a transferring half, so it is regular for it to make some noise. Nonetheless, in case you hear a loud grinding, squealing, or rattling noise, it might be an indication that the compressor is failing.
In the event you suspect that your compressor could also be defective, it is vital to name a certified HVAC technician for analysis and restore. Making an attempt to repair a compressor your self might be harmful and will void your guarantee. A technician will be capable to take a look at the compressor and decide if it must be changed. In some circumstances, the compressor could possibly be repaired, however in different circumstances, substitute could also be essential. In case your compressor is failing, it is vital to have it repaired or changed as quickly as attainable 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 liable for compressing refrigerant gasoline and sending it via the remainder of the system. A working compressor will sometimes make a buzzing or buzzing sound. This sound is often louder when the compressor is first beginning up, however it ought to regularly change into quieter because the compressor reaches its working pace.
If the compressor is making an uncommon noise, it might be an indication that there’s a drawback. Listed below are a number of the commonest noises {that a} compressor could make and what they may imply:
| Noise | Attainable Trigger |
|---|---|
| Buzzing or buzzing | Regular operation |
| Clicking | Unfastened or broken compressor |
| Whirring | Worn bearings |
| Screaming | Broken compressor |

Set an ammeter to the suitable present vary and join it to the compressor relay’s terminals. Make sure the meter’s polarity is right.
5. Deciphering the Readings
Desk 1: Typical Compressor Present Draw
| Compressor Dimension | 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 a better draw might recommend an issue with {the electrical} circuit.
Measuring Compressor Temperature
A compressor that’s too scorching 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 heart of the compressor. Press the set off and maintain it till the temperature studying stabilizes. Document the temperature.
The conventional 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 offers a common guideline for decoding compressor temperatures:
| Compressor Temperature | Attainable Trigger |
