Air and Heat Noise Troubleshooting For You

Tired of that racket every time you turn on the central air and heat unit? This article will provide you with a few tips to help you regain your peace and quiet.

Central air and heat furnace systems provide heat and cooling to the area where they are installed. Noises from these units can occur during operation regardless of the type of weather conditions going on outside. In many cases, these noises can be prevented by placing the condenser away for any debris that is deemed a threat. When that doesn’t do the trick, the tips found in the following article may just be the ticket.

Step 1 – Outside, take a look at the condenser unit and take a look through the top grille to inspect whether any damage has been caused to the blades by random objects that have made their way inside. These objects can range from tree limbs to small animals. If you are unable to properly inspect the blades, remove the grille. Blades that are slightly damages may be able to bend back into place. Blades that are bent badly will need to be replaced.

Step 2 – If there is no obvious and apparent obstruction to the blade, take a close look at the housing on the condenser unit. The noise could be caused by a loose fitting screw. Take a moment to tighten all screws, whether they appear undone or not, on the access panel to ensure that they are not the origin of the noise.

Step 3 – Power off the unit in order to check the motor of the fan. For this you will need a multi-tester device. Situate the device in a secure position and test for continuity and test each fan wire. As long as the tester shows continuity, you should be fine. If not continuity is present, you are looking at a motor replacement.

Step 4 – If the motor passes the continuity test, lube up the motor. Motor bearings could be another possibility of why your system is making such crazy noises. Lubrication should put an end to the issue for the foreseeable future.

Step 5 – Make sure the blower motor belt's tension is the appropriate amount. If it is too tight or too loose it could be attributed to excess noise. Press the belt down with your hand, right between the blower pulleys and motor. Adjust as needed. If you find that the belt is damaged or frayed, it’s probably a good idea to invest in a replacement.

Step 6 – If you get through each of these steps with no progress, then you may need to look into purchasing a new unit. Call up a trusted air and heat HVAC specialist and have them take a look to make certain you’ve covered all of your bases before hand. A trained professional may be able to spot a small problem that was overlooked, and hopefully provide you with a cost-efficient alternative to a replacement unit. In cases, where replacement is unavoidable, discuss your options with the technician to find out how to obtain the best bang for your buck. A little patience and research goes a long way; Be sure to cross off every possibility before deciding to spend the big bucks on a new model. This will hopefully solve your hair and heat woes for now!
