These Are the 6 Essential Parts of Your HVAC System

Do you know the main parts of your HVAC system? Many people don't. Knowing your HVAC parts will help your system run properly. And help you diagnose issues more quickly when there's a problem.

In this post, you'll discover six essential HVAC components. Knowing more about these parts saves you precious time, minimizes downtime, and keeps your system running beautifully.

1. Air Filters

Air filters might seem like a no-brainer. But they're often overlooked. This pleated fabric and paper fibers housed in cardboard are one of the most critical components of your system. Make sure to buy the right one.

Air filters help other HVAC parts perform better. Your filter's main purpose: to filter air circulating through your HVAC unit. Your facility or home's air passes through your HVAC system's filter. 

It helps you, your family, and your employees breathe in healthier air. You don't want them breathing in dirt and dust, and any bacteria in the air.

To add, a filter that's dirty minimizes airflow, causing your system to waste more electricity to move the air around. At worst, a clogged air filter can create airflow problems which can negatively affect your HVAC system.

2. The Belts

Your HVAC system has belts that help your system run properly. Belts wear over time. If they're broken they can affect how your system operates.

To prevent this from occurring, replace the belts when it's time. If the belt slips, it will cost you more in energy costs.

Do you hear an odd noise coming from your system? If you do, it most likely means you have a frayed belt that needs to be changed.

It's always a good idea to have your HVAC professional check your system annually. They will be able to warn you when a belt needs changing. If it breaks, it can be an expensive fix.

3. Fan Motor

A major component of your HVAC system is the fan motor. Fan motors ensure your AC system runs properly. They achieve this by circulating air through different areas of your home or business.

Ignoring a fan motor that needs maintenance can critically impact your HVAC unit. A popular problem is neglecting the fan motor's bearings and motor shaft.

You can get dirt build-up on bearings which makes your system overheat. This happens because the motor has to work harder than it's meant to run correctly. 

Considering lubricating the bearings on your own? Make sure you don't put too much grease on the bearings.

If this is your first time lubricating your system, refer to your manufacturer's directions to learn how to properly grease your system's bearings. Or call in an HVAC technician.

Routine maintenance and inspections of your fan and bearings are essential. They'll extend the lifespan of your air conditioner.

4. Capacitors

Another HVAC part your system needs is a capacitor. Capacitors enable your system to run and function correctly. Different systems require different capacitors. The size will be determined by the size of your HVAC motor.

Capacitors improve efficiency and give you starting torque. Make sure you choose a capacitor that works with your system.

If you get a low-quality capacitor, it can damage your motor. Ask your HVAC technician to examine your system to diagnose your capacitor to ensure it's operating properly.

5. Coil Condenser Cleaners

One of the things that can influence the performance of your HVAC system is when dirt forms on your condenser coil. Your system contains two kinds of coils: the condenser and evaporator coils.

Condensor coils emit the heat that accumulates. Evaporator coils extract the heat and humidity from your home or business. As the coils move warm air out of your home, it can build up dirt, dust, and bacteria as well as grease.

These unhealthy elements can cause a blockage. When this happens, your system works hard which can lead to wasting energy and affecting your system's performance.

To remedy the situation, have your condenser coil cleaned annually. If you have a service maintenance plan, your technician will know how to take care of your condenser coils.

6. Contactors

Contactors manage the location where your electricity gets delivered so you can stay comfortable in your home. Having a contactor you can depend on keeps your system running smoothly. 

The contactor acts like a receiver. When it's time to cool things down, your system sends a signal to your contactor. When it receives the proper signal, it gets lowered. This permits the air to flow properly.

After your thermostat completes the cooling cycle, the contactor raises again to prevent the flow of electricity. Contactors can malfunction when the compressor is damaged.

If you're not a professional, don't try to fix a contactor on your own because this HVAC component carries a high voltage. They can cause a hazard. Call a licensed technician.

Other HVAC parts your system needs include:

  • Fuses
  • Thermostat
  • Batteries for your thermostat

Is your thermostat not working correctly? It might just need batteries. At times, you'll need to change the fuse. By maintaining all your HVAC parts and accessories you'll have an efficient system that reaches optimal performance.
