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

It could be worthwhile to invest in a new unit when your home’s HVAC is a bit old and in need of repair. A residential HVAC expert can help you choose the right option for your home.

Most cooling systems rely on electricity to cool and heat homes, however certain gas-powered or propane air conditioners use natural gas to power furnaces and run condensers within a split system.

Evaporator

The evaporator coil of your air conditioner is what cools your home. The evaporator coil is located in a box that is attached to or inside 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 turns into a liquid, and absorbs heat from the air in your home.

The evaporator consists of one or more copper coils that are tightly packed. The refrigerant reaches the coils at low pressure, making it easier to transfer heat when it evaporates into gaseous form.

A fan blows warm air from your home over the coil that is used to evaporate. The air is cooled by the removal of heat from the evaporator which alters the refrigerant’s temperatures and lowers the temperature of your indoor air. The cooled air is then circulated through the ductwork of your home to each of the rooms.

The evaporator, unlike the compressor, only needs to raise the boiling point of the refrigerant down to a low temperature to ensure efficient air cooling. The evaporator makes use of its own fan in order to accomplish this final goal.

The metering device of the evaporator assists to ensure that the refrigerant maintains a constant level of liquid within it. The low-side float is designed to open when there is no liquid in the evaporator, and it closes when sees liquid enter the coils.

There are two main types of evaporators: cased and uncased. The most commonly used type of evaporator that you will find in your home is a cased model. It is housed inside the casing made of metal that covers the air conditioning unit. A non-cased evaporator is the same, except it doesn’t have the outer shell that protects it.

Both evaporators have the same purpose, however it’s important to select a model that can satisfy your home’s particular needs. For example, some models are more suited to harsher working environments, while others are better suited for milder conditions. Consider how easy it is to clean and maintain your evaporator. This can help you save time, money and effort.

Condenser

The condenser is one of three main components of your air conditioning system which helps to keep it running efficiently. It is located outside the house, connected to the evaporator coil via refrigerant lines and contains an array of fans and metal fins which work to eliminate heat from the refrigerant gas that was transported here from the evaporator. The heat that is emitted allows the refrigerant to be cooled and transform into a liquid state.

A compressor is attached to the condenser unit and is used to pressurize the low-pressure liquid refrigerant that has been taken from the evaporator coil. The squeezing action of the compressor raises the temperature of the coolant, which then passes into the condenser coils to take in heat that is not being absorbed by the air around it. After the cooling cycle is completed, the refrigerant will be moved 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 even roofing shingles, can cause damage to the condenser. The addition of the universal HVAC condenser cover to your heating and cooling system can help safeguard the equipment from accidental damage when it isn’t in use.

It is also essential to ensure that the condenser is not shaded. This can decrease air flow, which can force the compressor to work harder to cool your home. This can result in more energy costs and a possible loss of refrigerant.

Regular maintenance will ensure that your HVAC system is running efficiently. Regularly having a professional technician examine every major component of your HVAC system can aid in preventing major issues. A professional service team can avoid problems by checking regularly the refrigerant level. Follow these steps to extend the life of your cooling and heating system and reduce 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 is like the blood in your body, as it moves coolant back and forth between the condenser and evaporator coils. If something goes wrong with the compressor, it will stop the condenser and evaporator from doing their job and will make your home uncomfortably warm.

There are a myriad of different kinds of HVAC compressors. Each one has its own benefits and drawbacks. A reciprocating compressor, for example, has a piston moving upwards and downwards within the piston. This produces a suction that draws in the refrigerant. As the piston moves downwards it decreases the volume of gas. A discharge valve opens to let the pressurized refrigeration to the condenser.

This type of compressor is also equipped with a clutch, and a crankshaft that aids the piston to compress air. A rotary compressor, on the other side, has blades within the cylinder which help compress the air. This kind of compressor is quiet, making it an ideal choice for residential applications.

Both kinds of HVAC compressors are designed to raise the temperature of the refrigerant liquid as it is being compressed, so that the vapor that leaves the compressor is high-temperature and high pressure. Since heat naturally flows from high-temperature substances to lower-temperature ones the hot vapor is able to move into the evaporator coils and return to its liquid state.

While you can’t avoid the chance of having problems with the compressor, you can avoid the majority of AC issues by keeping track of your maintenance schedule. This will ensure that your equipment will last for many years and provide peace of mind that your home will always be comfortable. If you do encounter problems with your compressor then your Griffith Energy Services technician can help you decide what repair options are most suitable for you.

Thermostat

The thermostat is your heating and cooling system’s brain, and it decides the frequency and manner in which the system is turned on and off. It determines the temperature of the air and compares it to a preset desired level. The thermostat will send an indication to alter the temperature if it is off a few degrees. The majority of modern thermostats gauge temperature using the digital sensor, also known as the thermosistor. The thermistor is composed of two different metals that expand at different rates when they get hot and cause them to bend in opposite directions. When the thermistor reaches its temperature it sends a signal to the circuit board to start your heating or AC system.

The touchscreens on the latest models make it easy to program and operate. A lot of thermostats are programmed to automatically cool and heat your home according to specific times. This means you don’t have to worry about having to manually set them each day. In addition, they provide reports on energy consumption so that you can figure out how to reduce costs.

If you have an older electromechanical model the way that it works is a bit more complicated. It consists of a bimetallic strip which is bonded to a vial using mercury. When the temperature fluctuates in the vial, it causes the mercury in the vial to move in a way, interrupting or completing an electrical circuit. When the vial tipping the thermostat, it turns on the heating and cooling system.

To keep your thermostat in good working condition It is essential to be sure to clean it on a regular basis to remove any dust that has accumulated. Also, make sure that it isn’t crooked or loose. In certain cases the thermostat may be having trouble with its readings due to a dirty evaporator coil or the thermistor being damaged. In that scenario, you’ll need to call a professional to fix the problem for you. If you are experiencing a other issue, like a blank display, try changing your batteries or checking that your breaker isn’t connected. This is a good illustration of how you can make your HVAC system more efficient by understanding it and maximizing its use.
