Which Parts Of An HVAC System Can You Replace On Your Own?

HVAC systems can be complex, but the parts that make them work are relatively simple. In this post, we’ll break down the different components of an HVAC system and discuss which ones you can replace on your own.

A Furnace’s Blower Motor

If you have a furnace with a blower motor, it’s important to replace it if it starts making noise or stops working. The blower motor is the part of your HVAC parts system that pushes air through the ductwork and into your home.

When replacing an old blower motor with a new one–or even just cleaning off dust buildup around its blades–make sure it matches up exactly with what was originally installed by measuring both dimensions (height x width x depth) before purchase; most modern models should fit well enough without needing adjustment after installation as long as everything else stays put during operation hours!

An Air Conditioner’s Condenser

The condenser is the parts of an air conditioner that cools the refrigerant. It’s located outside of your home and can be accessed through a panel on the side of your house or garage, depending on where you live. The condenser needs to be cleaned periodically because dust and dirt buildup can cause problems with its operation and lead to higher energy bills. If you’re comfortable working with tools, then cleaning this part yourself may save some money over hiring someone else to do it for you!

An Air Conditioner’s Compressor

The compressor is the central component of an HVAC parts system. It’s what pumps refrigerant through your home and into coils, where it changes from a liquid to a gas and absorbs heat from your house. The more efficient your compressor is at doing this, the less electricity you’ll use and the more money you’ll save on utility bills.

Compressors are also large–usually about five feet long by two feet wide–and heavy; they weigh between 75 pounds and 200 pounds depending on how many tons (or BTUs) of cooling capacity they provide for your home.

A Heat Pump Outdoor Fan Motor

The heat pump outdoor fan motor is responsible for moving air through the heat pump’s coils. If it’s broken, you will need to replace it with another standard size motor found at any hardware store.


HVAC replacement parts are essential for maintaining and repairing heating, ventilation, and air conditioning systems. These parts ensure the smooth operation and longevity of the HVAC system, allowing for efficient and comfortable indoor environments.

With all of these parts, you can see that there’s plenty of opportunity to save money by doing your own HVAC repairs. With the right tools and knowledge, you can save yourself hundreds or even thousands on heating and cooling costs each year!
