The air conditioner is making a strange sound.
Air conditioners make sound, but at times, they will make a sound you do not recognize, and that could indicate a problem. Strange noises might be a puzzle, but frequently, a noisy air conditioner is a belt problem, especially if it’s making a squealing sound. The belt might be improperly aligned or need replacing. A grinding sound usually indicates a problem with the engine’s bearings. Pinging or popping might be a loose flap of metal in the ductwork, and rattling noises may indicate which you will need to tighten cover panels.
The condenser is not running.
Be sure the condenser is getting power. Confirm that the device is plugged in and there is not a blown fuse or tripped circuit breaker. A condenser that will not operate might have problems getting the cooling signal from the thermostat. You also need to check for security switches as well as the oil level. Check for refrigerant pressure, as when refrigerant has leaked, the low-pressure safety might have been switched.
The Filter Is Dirty
Air conditioner filters will need to be replaced at least every 2 months. When that does not happen, they become too cluttered. Due to that, the air can not flow too and the quality of it deteriorates.
Fixing this problem is really easy. Replace your filters and set an alarm on your telephone so you don’t forget the next time you will need to do it.
AC Unit Blows Warm Air
An incorrectly set thermostat (sounds silly, but we have seen it happen).
A restriction in airflow. Either the air filter may have to be replaced or in case you haven’t had maintenance done on your air conditioner this year, which might be a cause.
The outside unit is not getting electricity. A circuit could be actuated, or even a fuse blown. If that is continually occurring, it probably points to a larger problem — such as your AC unit with too much power.
It might also be an issue with the compressor/outside unit, or your unit could be low on refrigerant. It’s also possible there is a broken or disconnected return.
In any case (besides the thermostat) your very best bet is to call in an air conditioner technician to check at the problem.
How to Clean Dirty A/C Coils
In cases like this, a thorough cleaning will fix the issue. Alas, the coils are located within the unit, so while cleaning them isn’t complex, getting to them is. It is usually better to call in a professional for this repair. Fortunately, while the repairman is there, they can ensure there are no leaks in the coils and ensure that your system is functioning in tip-top form.
Clean your ducts
Ducts are the airways and tubes which the air flows through to get into the numerous vents in the home. While the intake filters capture the huge majority of dust, pet hair, and dirt, occasionally debris gets through. If you don’t regularly clean your ducts, then debris can build up over time (with the support of static electricity) and cause a blockage in the ducts which reduces airflow. If air is not flowing, then air is not cooling.
Normally, it’s a fantastic idea to clean your air ducts after annually by a professional to make sure all the dirt and dust particles throughout the whole system can be addressed instead of just what you are able to reach.
