What Parts of My AC Can Be Replaced?
Posted On: April 8, 2024
In an air conditioning system, various components can be replaced depending on the type of issue you're experiencing or the maintenance required. Here are some common parts that can be replaced in an AC system:
-
Air Filters: These should be replaced regularly, typically every 1-3 months, depending on usage and the type of filter.
-
Thermostat: If your thermostat is malfunctioning or outdated, it can be replaced with a newer model.
-
Capacitors: Capacitors are responsible for starting the compressor and fan motors. If they fail, the motors won't start properly. They can be replaced relatively easily.
-
Compressor: The compressor is a vital component that circulates refrigerant through the system. If it fails, it may need to be replaced, though this can be a more expensive repair.
-
Condenser Coil: Over time, condenser coils can corrode or get damaged. They can be replaced if necessary.
-
Evaporator Coil: Similar to the condenser coil, the evaporator coil can also degrade over time and may need to be replaced if it becomes damaged or corroded.
-
Fan Motors: If the fan motors in the condenser unit or air handler fail, they can be replaced individually.
-
Refrigerant Lines: If there's a leak in the refrigerant lines, they can be repaired or replaced.
-
Expansion Valve: This component regulates the flow of refrigerant into the evaporator coil. If it malfunctions, it may need to be replaced.
-
Circuit Board: The circuit board controls the various functions of the AC unit. If it fails, it can be replaced.
-
Contactor: The contactor is responsible for controlling the power supply to the compressor and condenser fan motor. If it fails, it can be replaced.
-
Float Switch: This safety device shuts off the AC unit if the condensate drain becomes clogged. It can be replaced if it malfunctions.
It's important to note that while some of these parts can be replaced by homeowners with the necessary knowledge and tools, others may require the expertise of a professional HVAC technician. Additionally, it's often recommended to have regular maintenance performed by a professional to prevent issues and ensure the efficient operation of your AC system.

We are very happy to recommend this company to everyone. Our furnace broke down on Sunday morning. We phoned them and before noon Grant the owner showed up. He worked on the furnace for about a hour not wanting to give up to fix the problem. The furnace was 17 years old. I was the one talking about replacing it. End result was the next day it was all done. On the Sunday Bob came over with heaters to warm up the house. We decided to replace the water heater at the same time. Thanks Grant for the excellent work. Thumbs up.

Right on time. Explained how to work the HRV in a different way so the house would not be so dry. Changed my whole house water filter for me as well. Friendly, helpful, caring service!

TwinTech is an excellent and honest company! I called them for a second opinion after being told by another company that I needed to replace my furnace. Turns out this was not the case at all! I did not need a new furnace. TwinTech did not push to make an unnecessary sale and saved me from a huge expense. Bob and Mitch were extremely professional and above all honest! I definitely recommend TwinTech!

I returned from vacation to find my AC unit on the Fritz. After calling way too many places I connected with TwinTech. Ive used the company in the past for my furnace so I was happy when I recognized Greg at my front door. Hes great and the service is always top notch. Id highly recommend using twintech for honest, superior service in the Durham region. Thanks!

I called Twin Tech when my air conditioning stopped working. Greg came over to diagnose the issue - the same day. He was able to diagnose the issue and resolve it quite quickly. Although it was a quick fix, Greg was very thorough in explaining the issue and provided great advice. Not to mention, I felt very comfortable having Greg in my home - which I consider very important when hiring a service provider. Twin Tech will be my go-to from now on. Thank you!!
