What is An AC Condenser Unit?
Are you comfortable sitting in the room you’re sitting in?
If so, chances are you can thank an AC condenser unit. The condenser unit on your cooling system is designed to keep your indoor space as hot or cool as you want it.
But what exactly is an A/C condenser, and how does it work?
What the AC Condenser Unit Does in Your Cooling System
An AC condenser’s primary job is to release heat from the refrigerant to the outside air after it has absorbed indoor heat.
It works along with your compressor, which pressurizes the refrigerant and sends it to the condenser coils.
That is the technical reality of what an AC condenser unit does, but what you really need to know is that without it your AC won’t blow cool air.
It absorbs heat inside your home and magically transforms it into cool air.
Main Parts of a Condenser Unit (What They Do)
The key components of a condenser unit include a compressor, fan, coils, and fins.
A compressor is like the heart of the system, it pumps refrigerant through the unit under high pressure.
Condenser coils and fins allow the refrigerant to release heat as it cools and condenses into a liquid.
The fan and motor of the condenser unit help expel the heat from the coils by blowing outdoor air across them to help with the cooling process.
Common AC Condenser Issues & When To Call A Pro
The common problems with an AC condenser unit include blocked airflow, refrigerant leaks, and failed capacitors.
Some warning signs of failure of your unit might include:
Overheating or restricted airflow
If you notice debris or vegetation beginning to creep up over your condenser unit, you need to clear it as soon as possible. It can restrict airflow and cause your unit to work harder.
Refrigerant leaks
Leaks can cause underperformance in your system and should be addressed by a certified technician as quickly as possible.
Electrical or mechanical failure issues
If your fan motor breaks or if you have a bad capacitor, your unit won’t run effectively. Speak with a contractor to have this issue taken care of as quickly as you can.
Frequently Asked Questions
Is an AC compressor and condenser the same thing?
No. The compressor of your AC is a component inside the condenser unit that pressurizes refrigerant. The condenser is the entire outdoor unit that is responsible for releasing heat.
How much does it cost to replace an AC condenser?
It costs between $1,200 to $4,000 depending on the type of unit and labor involved.
How do I tell if my AC condenser is bad?
Do you notice any weird smells or noises coming from your unit? Does it frequently shutoff? Will the outdoor unit not turn on all the way? Any of these issues mean your AC condenser is bad.
What happens when your AC condenser goes out?
If your AC condenser goes out, your AC system won’t cool your home properly. It will typically blow warm air or shut off entirely.
Is the outside Ac unit a condenser or a compressor?
The outside unit of your AC is called the condenser. It has the compressor and other key components.
Should I replace AC condenser when replacing compressor?
We recommend replacing both, particularly if your system is older or if there’s contamination in the lines.
