What Are the Main Parts of Your Heating Air Conditioning Unit?

It could be worthwhile to invest in a new unit if your home’s air conditioner is old and in need of repairs. A residential HVAC expert can assist you in selecting the best option for your home.

Most cooling systems rely upon electricity to cool and heat homes. However, certain propane or gas-powered air conditioners, use natural gas to fuel furnaces and operate condensers within a split system.

Evaporator

The evaporator coil inside your air conditioner is what cools your home. The evaporator coil can be found in a container that is attached to or within your gas furnace (if you have one) or in an air handler, in the event that you don’t have. The evaporator is the place where the refrigerant is transformed into a liquid, and absorbs heat in your home’s air.

The evaporator has one or more copper coils tightly packed. The refrigerant has a low pressure when it reaches the coils, making it easier to transfer heat.

A fan blows the warm air from your home to the coil that is used to evaporate. The air is cooled by the removal of heat from the evaporator, which alters the refrigerant’s temperature and lowers your indoor air temperature. The cooled air then moves through your home’s ductwork to every room and circulates until it returns to the air conditioning system via return ducts.

Contrary to the compressor, which has to create refrigerant gas at high temperatures to ensure efficient cooling, the evaporator only has to raise its boiling point to a low temperature for effective air cooling. The evaporator makes use of its own fans in order to accomplish this objective.

The evaporator metering system ensures that the refrigerant in the liquid is always at the same level. The low-side float is designed to be open when there’s no liquid in the evaporator and it closes when it sees liquid enter the coils.

There are two types of evaporators: noncased and cased. A cased evaporator is the one you’ll most likely to see in your home since it is enclosed inside the metal casing of your air conditioning unit. Uncased evaporators are similar however it doesn’t come with the protective outer shell.

While both evaporators have the same purpose, it’s important to select a model capable of meeting the requirements of your house. Some models are better suited for harsher environments, whereas others might be more appropriate for milder conditions. Also, you should think about how easy it will be to clean and maintain the evaporator as this could save you time, money and hassle in the long in the long.

Condenser

The condenser is one of three major components of the air conditioning system in your home which helps to keep it running efficiently. The condenser is situated outside the home and is connected to the evaporator via refrigerant pipes. It contains metal fins and fans which work to remove the heat from the refrigerant which was transported from the evaporator. The heat removed allows the refrigerant to cool down and transform back into a liquid state.

A compressor is attached to an condenser unit. It is used to pressurize low-pressure liquid refrigeration that is pumped out of the evaporator coil. The compressor’s squeezing action raises the temperature, which is transferred to the condenser unit to absorb heat trapped in the air. After the cooling cycle is completed the refrigerant will be pushed into the compressor to be pressurized prior to being pumped back to the evaporator coil.

Since the condenser is situated outdoors, it is susceptible to the elements. Leaves and twigs, grass clippings, or roofing shingles, can cause damage to the condenser. The addition of an universal HVAC condenser cover to your heating and cooling system can help to protect the equipment from damage even when it’s not in use.

It is also important to not shade the condenser. This can reduce the flow of air, causing the compressor to work harder in order to cool your home. This could lead to increased energy costs and potential loss of refrigerant.

Regular maintenance of your HVAC system will help to ensure that the condenser is operating effectively. A professional service technician inspect all of the major components of your system on a regular basis can help to prevent any major issues from arising. Additionally, having a professional service team check your refrigerant levels regularly can help avoid any issues from arising. By following these easy steps, you’ll be able to prolong the longevity of your cooling and heating system and reduce your energy bills.

Compressor

The compressor is the main component of your air conditioner. It circulates refrigerant through the system, ensuring that everything stays cool. It’s like the blood that flows through your body when it pumps the coolant between your evaporator coils as well as the condenser. If the compressor fails and the evaporator fails, it will not be able perform its job and your home will get extremely hot.

There are a variety of HVAC compressors, and each one has distinct advantages and disadvantages. For instance the reciprocating compressor is comprised of a piston that moves up and down within the cylinder. This movement creates suction that draws in refrigerant. As the piston moves downward, it reduces gas volume. A discharge valve opens to release the pressurized refrigeration into the condenser.

This type of compressor is equipped with a clutch and a crankshaft that aids the piston compress air. A rotary compressor has blades inside the cylinder to aid in compressing the air. This type of compressor is very quiet, making it a popular option for residential use.

The HVAC compressors of both types are designed to raise temperature of the liquid as it is compressed. This results in an extremely high-temperature, high-pressure liquid. Since heat naturally flows from higher temperature substances to lower-temperature ones, the hot vapor is able to move into the evaporator coils and change back to its original liquid state.

While you can’t prevent the possibility of having a problem with your compressor, you can stop the majority of AC issues by being on top of your maintenance schedule. This will ensure that your equipment will last for years and give you peace-of-mind knowing that your home will always be comfortable. If you do encounter a problem with the compressor then your Griffith Energy Services technician can assist you in determining what repairs are the best for you.

Thermostat

The thermostat is the brains of your heating and cooling system, allowing it to regulate the timing and manner in which it turns off and on. It compares the temperature of the air to a pre-set desired level. If it is off by one or two degrees, the thermostat will send an electronic signal to bring it towards the desired temperature. The majority of modern thermostats gauge temperature by using an electronic sensor referred to as a thermistor. The thermistor consists of two different metals that expand at different rates when they heat up, causing them to bend in opposite directions. When the thermistor is at its temperature set it sends a signal to the circuit board to start your heating or AC system.

The touchscreens on the newer models make it simple to program and operate. Many thermostats are programmed to automatically heat and cool your home according to specific times. This means you don’t have to worry about having to manually set them every day. They also provide information on energy usage so that you can discover ways to reduce expenses.

If you have an older electromechanical model, it is somewhat more complicated. It is made up of a bimetallic band which is joined to mercury in the vial. When temperatures change, the mercury in a vial tilts, completing or breaking a circuit. When the vial is tilted, it triggers the thermostat to start the heating or cooling system.

To ensure that your thermostat is in good working condition It is essential to clean it regularly to remove any dust that has built up. Also, make sure that it is not crooked or loose. In some cases the thermostat could be having trouble in its readings due to an evaporator coil that is dirty or the thermistor being damaged. In that scenario, you’ll require an expert to fix it for you. If you’re experiencing a different issue, for instance a blank display try replacing your batteries or making sure that your breaker isn’t connected. This is a great example of how you can improve the efficiency of your HVAC system more efficient by learning about it and maximizing its use.
