You can resolve some issues with your heating, ventilation, and air conditioning unit by simply cleaning the coils and changing the filters. However, many homeowners ignore these minor concerns, and with time, they lead to complete HVAC failure. You can prevent this from happening by having a regular maintenance schedule for your unit and sticking to it. Here are the three most common issues that affect the appliance and how to deal with them. 

Mechanical Wear and Tear

Your HVAC unit has many mechanical parts working together to achieve its overall function. Over the years, some of the components will experience mechanical wear and tear because they are always in use. Worn-out parts bring down the overall efficiency of the HVAC system. The bits prone to this damage include belts and bearings. When these parts wear out, the unit starts to overheat or experience poor heating. You might also experience airflow issues when the parts wear out. Get the damaged parts repaired to restore the unit's operational efficiency. 

Unusual Noises

The furnace makes some noises as part of its normal operations. However, other noises indicate that the system might be damaged and need repairs. For example, the whining and squealing of the motor show that an inducer motor has failing bearings. You might need to replace the inducer motor to prevent the system from complete failure. Sometimes, the noises come from poor airflow and the accumulation of grime in the burners. You should call a maintenance expert to assess the heating system and resolve the issues. Ignoring these sounds could be exposing your home to a potential fire hazard. 

Water Leaking From the System

Water leaks are a common issue with the heating system. Air conditioners and furnaces produce some form of condensate during their operations. The system has drain pipes to remove and drain water away. However, if the drain lines have a clog, you will experience blockage, which will result in water dripping all over the place. You can use simple hacks like pouring bleach down the drains occasionally to clear any blockages that could be forming. Leaks could also come from the heat exchanger, the collector box, or the evaporator drain. It is wise to let a technician assess the source of the leak to determine how to fix it.

You should call an HVAC service immediately if you suspect that your HVAC unit might need repairs. They will perform a system assessment and determine whether you need to repair components to restore the functionality and efficiency of the unit.
