Belts And Bearings? Air Conditioning Repair Issues Related To These Small HVAC Components
Posted on: 24 February 2022
When seeking information on air conditioning repair issues, homeowners often find that the information and advice offered tends to skew toward major repair issues that tend to be complicated and expensive to address. While repairing compressor leaks and condenser malfunctions are necessary and deserve considerable attention, many homeowners could also benefit from having more information about the smaller air conditioning repair issues they may face.
For example, air conditioning systems that are forced to continue operating with worn belts or bearings will be more likely to need progressively intensive repairs as time passes, damage worsens, and the scope of the repair issue expands. Homeowners who would like to learn more about the dangers posed by worn belts and bearings for their air conditioning system can use the following information to become better informed.
Signs of belt wear
Air conditioning systems depend on the HVAC blower fan to collect and distribute the cold air it creates throughout the home. When the belt is in good condition and working properly, the system can work quietly and efficiently to evenly push the cold air through the ducts to cool the entire home. As the belt ages and experiences wear, it can begin to slip and lose contact with the pulleys. Homeowners who notice that their air conditioning system is beginning to emit squealing noises when the fan cycles on should immediately suspect belt wear and contact their air conditioning repair service to have the belt replaced.
Signs of bearing wear
Electric motors used to power fans in residential air conditioning systems function through the use of bearings that fit snugly between the motor housing and the armature. The round, smooth shape of each bearing ensures that it can support axial loads and reduce friction while transferring power to the fan assembly for the purpose of moving cold air through the air conditioning ducts. Bearings that are correctly installed and in good condition with adequate lubrication can be expected to operate quietly for years of dependable service.
However, when bearings experience wear or damage from age, insufficient lubrication, or dusty conditions, the AC system will need to work harder to move the cold air through the ducts. In addition to higher electricity bills, homeowners with worn AC system bearings may also notice a declining cooling experience and hear rattling noises when the air conditioning fan is running. Homeowners who notice any signs of bearing wear should immediately contact a reputable air conditioning service contractor to replace the bearings and check for wear issues in the surrounding components.
