Key Points
- HVAC hardware, like any modern technology, can break down or fail. Replacement parts grant the option to restore core functionality to your heating and cooling system before swapping out for a new unit.
- IWAE now makes BOM diagrams that provide easy access to replacement parts that are guaranteed to be compatible with the listed system.
- Replacement parts include blowers, casing, coils, compressors, control boards, electrical sensors, fan blades, heating components, motors, piping, and more.
After years of reliable service, almost any electronic system will inevitably need a little TLC, like your HVAC system, for example. Most of us might think that means it’s time to throw out our systems entirely, but wait! You don’t need to look for a full new HVAC system when performance starts to dip. You can enjoy top-tier results again by simply replacing the components that are giving out. From fans and casing to piping and electronics, almost any part of your heating and cooling system can be swapped out to bring the climate control in your house back up to snuff.


Introducing: IWAE’s BOM Diagrams
If you’ve been browsing our website lately, you’ll have noticed a new feature: BOM diagrams. You can find these helpful parts guides under the “parts” tab on select items. With this diagram, you can easily see which parts are standard for your HVAC unit and follow embedded links to available replacement parts. Check out an example with the 12k BTU 23.5 SEER2 MrCool DIY Ductless Heat Pump Condenser. For any part we carry, you can easily click on the number beside it on the diagram and add it to your cart. Sounds simple, right? Because it is!
Explore the Components You Need


Replacement Blowers & Fan Blades
Blowers and fan blades work closely together. The blower is a part of your condenser that influences the cooling process, holding responsibility for pushing the cooled air through the ductwork in order to disperse it through your space. Working in tandem with the evaporator coil and the condenser unit, the blower is an integral piece of the system to ensure your space enjoys comfortable climate control all year long.
The various fans in your system serve a range of purposes. Axial fans are responsible for situations with low static pressure and airflow, usually found in towers, condensers, and cooling applications. Centrifugal fans work in a similar way but are designed for high-pressure.
MrCool Blowers & Fan Blades
MrCool parts are the perfect replacement for your MrCool system. Designed for MrCool by MrCool, these components are ideal to keep your system running smoothly. In the striking MrCool blue or other tones that match the aesthetic of your system, you’ll enjoy getting back to the kind of results you’ve grown accustomed to.
Casing & Hardware Parts
Effectively protecting the internal components of your HVAC system, the casing and external hardware keep the mechanical parts and hookups safe from inclement weather. From water collectors to panel assemblies and more, the outside protections for your system are the last line of defense to keep inclement weather, childhood toys, accidents, and any other hazards from throwing a wrench into the system.
Replacing Hardware on HVAC Systems
Keeping moisture from influencing the technology in your HVAC system is one of the most important roles. While anything can potentially cause harm to the paneling, including hail, rocks, baseballs, and any other unexpected events, replacing these pieces should always be a top priority to keep your indoor ambiance as comfortable as possible.
Coil & Piping HVAC Parts
The coils and piping in your system are responsible for handling the flow of refrigerant. Keeping the pipes securely fastened to prevent leaks, clean of particulates to ensure reliable flow, and effective at controlling the amount of refrigerant for efficient heating and cooling, a problem in the coil and piping can throw an enormous wrench in the results you receive from your system.
MrCool Replacement Coil & Piping Parts
From quick connectors to four-way valves and everything in between, MrCool has the parts you need for your system. No vac line sets can easily be changed in and out if any leaks or cuts form, quick connectors can be swapped out if the coupler loses its seal, and your system can get back to doing what it does best: keeping your home comfortable in any conditions.
Compressor Replacement Parts
In charge of pressurizing the refrigerant so it can draw out the heat from the air, providing the cooling release from sweltering summer heat. If the compressor fails, you and your loved ones will be subjected to the intense heat waves without the relief of well-conditioned air, as one of the components that can make your system feel fully malfunctional, keeping the compressor running is crucial for comfort.
Compressor for MrCool Systems
Providing a perfect fit into your MrCool system, a replacement compressor from the same manufacturer is the best way to ensure your home can fend off the summer sun. While third-party equivalents can be found for most HVAC parts, the best way to get the most consistent results while guaranteeing a perfect fit into the system is to secure the same part from the same brand, designed for your system’s design and specifications.
Electrical Sensors & Control Boards
Handling the electrical impulses that read in conditional information, the sensors and control boards in your heating and cooling system are what tell your setup to power up, power down, and at what strength to run. Whether your system has started to malfunction, has lost efficiency, or no longer turns on or runs as expected, the control board is what ensures the right choices are made regarding your temperature regulation.
Replacement Electrical Parts for HVAC Systems
Everything from pipe sensors to control boxes, display boxes, and transformers can cause problems that ruin the comfort you experience in your home. Making sure these pieces stay performing at peak is how you keep your system running efficiently and safely. Whether it’s allowing you to input your preferred settings and monitoring the conditions in your home, the electronic systems in your HVAC setup are the brain that keeps the system running.


Heating Components
Fending off the chill of winter weather is impossible without the heating elements in your climate control system. Components like thermostatic expansion valves, or TXVs, handle the flow of refrigerant to switch between heating and cooling modes while heat kits simply supply additional heating power, keeping comfortable temperatures in even the harshest weather.
Heating Component Replacements for HVAC Systems
Ensuring you and your family can stay safely warm is one of the main reasons why humans have worked so hard to perfect indoor living. It doesn’t matter if you’re just a little more chilly than you expect to be or if the air being pushed through your vents is lukewarm at best; replacing any worn-down or broken components in your system is the easiest and most cost-effective way to restore the heating performance you’ve come to expect from your system.
Motor Replacement Parts
Stepper motors and brushless DC motors handle important steps in the climate control process, making sure the position of the vents will distribute airflow where it’s needed and providing consistent airflow. Damaged or broken motors can lead to uncomfortable conditions within your space, even when the air that does come out of the vents maintains the kind of temperatures that you’re looking for.
Motors for MrCool Systems
MrCool replacement motors are designed for quick and easy installation, letting any licensed technician get your system back to producing the unmatched temperature regulation and control that you’ve gotten accustomed to. The perfect size for your system and requiring no kind of adapters, replacing MrCool with MrCool is the best way to keep your space comfortable.
