Learn Which HVAC Parts Will Be First Up to Be Replaced

Your HVAC system is perhaps the most complex system in your home. It has moving parts, electrical components, filters, and air ducts, and it uses the natural movement of heat energy to cool and heat your home. So, when something goes wrong, it can be quite perplexing and difficult to pinpoint. Read on to learn about the parts that will most likely need to be replaced first and the best practices for the prevention of issues.

Disposable Air Filters

As a homeowner with a vested interest in the well-being of your HVAC system, the most important first replacement part is your HVAC filter. The air filter protects your central cooling and heating unit from the damage that dust and debris buildup can cause.

Change the filter according to the manufacturer’s recommendation — or sooner. For example, a pleated filter may be good for three months, except during the height of the cooling months when your AC is going most of the time. Check it monthly during these periods.

Electrical Components

A high percentage of first-replacement HVAC repair calls are due to electrical component failure. Capacitors and relays wear out after about five years (as indicated by a clicking noise and no airflow) and need to be replaced.

Blower Motor Failure

The main HVAC part that your air filter protects is the blower motor. For HVAC systems that aren’t well maintained, this is one of the first replacement-part repairs a homeowner may experience. Furthermore, it is a costly one, which is why regular professional HVAC maintenance and filter changes are so important.

Compressor Troubles

The compressor is the heart of your HVAC system because it pumps refrigerant between the evaporator and the condenser. The refrigerant extracts heat from your home during the cooling months and emits heat during the heating months.

The compressor is generally not the first replacement part on the list, but if you’re experiencing droning sounds or whirring noises from the outside HVAC unit and poor cooling or heating, give your HVAC technician a call.

The best strategy regarding first replacement parts is preventive maintenance. Contact Hansberger Refrigeration and Electric Company for your HVAC needs.
