In air conditioners, the refrigerant is cooled at the condenser into a warm liquid, and passes through a pipe into the evaporator coil where it expands and cools. In heat pumps, the hot gas is pumped directly to the evaporator coil to provide heat. Find a Lennox Dealer Near You. Find a Lennox dealer near you to meet all your home comfort needs. Search Dealers. Most leaks can be traced back to a broken coil or a worn-out seal. Do all of the components in air conditioning units work the same way for all models?
Not quite. There are a few notable variations to understand. In this unit, all of the key components are packaged together into a small unit that is placed, as its name implies, in your window opening. In a window unit, the evaporator coils will be located close to the front of the unit, with the condenser coils moved to the back. These allow hot air to escape from the condenser coil. In a packaged HVAC system, the major components evaporator coils, condenser, and compressor are all housed together in the same unit.
This saves space indoors, as the exterior unit is usually placed on a cement slab outside the structure, or sometimes on the ceiling of the home or commercial building. With this setup, the exterior system ties into a system of specialty-made ductwork, which connects the outdoor cabinet to the packaged central AC functions that are all controlled indoors. A split AC system, on the other hand, does not contain as many components outdoors. As such, it is usually reserved for spaces that have the room to house a larger-sized indoor unit.
With a split system, only the condenser and compressor will be located in the outdoor cabinet. Meanwhile, a special copper tube known as a line set , connects the interior and exterior components and moves cold air to the whole house.
The outdoor condenser unit helps eliminate the heat absorbed by the refrigerant. In many cases, split systems can be more efficient than packaged HVAC systems. In a vehicle, the AC condenser will be located near your engine radiator. Yet, besides that form change, the system performs most of the same functions as the condenser in your home unit. This is the key component that helps cool the refrigerant and convert it back into liquid form. Scheduling regular preventative maintenance checks with your local team of HVAC technicians is a great way to stay on top of any problems and help reverse them before they turn into a bigger headache.
What could happen to your condenser unit to cause it to become damaged? There are a few issues that can occur with normal wear and tear. Over time, you might notice the following problems:. If any of these red flags occur, you might not notice an immediate decline in operation. Without a great-quality condenser, your overall HVAC system will have to work much harder to generate cool air and pump it throughout your home in order to reach your pre-set temperature. You might not realize that your system is working much harder due to a breakdown at your condenser unit.
If the issue occurs in your vehicle, this decreased output will result in lower fuel efficiency, causing you to use more gas and fill up more often. Due to their small size, these leaks can be very difficult to find and fix, and many HVAC technicians will recommend replacing a cracked coil or condenser unit rather than repairing it or patching it.
Other times, the issues with your condenser will be more visible and obvious. If you notice a lot more fluid pooling up around your HVAC system than usual condensation would create, this could point to a problem with your unit. However, your best course of action is to always allow a professional team of technicians to take a look at your systems. While there are plenty of online tutorials and resources designed to help you perform your own repairs, you could ultimately end up causing more harm and spending more money if your attempts to correct an issue do not go as planned.
When you take your car to a reputable local dealership or body shop, their inspections should be thorough and will include checks on all of your major engine components, including your vehicular AC system. Is your AC system a window unit? If so, you have a few special considerations to keep in mind. While your unit should be weather-resistant and capable of withstanding the elements, you want to take measures to expose it to as little moisture as possible.
Doing so could cause moisture to enter the condenser. Over time, this can lead to corrosion. When this occurs, your unit will become more vulnerable to cracked coils and refrigerant leaks. While minor rainfalls are fine, try to avoid using your unit if you know a severe storm is on the way!
Condensers contain a compressor, refrigerant, one or more pumps, fans and a system of tubing to manage the flow of the refrigerant. All condensers are "heat exchangers;" fans force air over the metal coils to cool areas "outbound" from the condenser, or it is ventilated on the "return" warm side.
Condensers range in size from small units in office water fountains to huge machines used to air condition buildings as large as the Pentagon. Condenser units facilitate living and working in areas that were once considered uninhabitable, heat pumps provide efficient heating for temperate locales and refrigeration extends the life of perishable food.
