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

It could be worthwhile to invest in a new unit in the event that your home’s air conditioner is a bit old and in need of repairs. A residential HVAC expert can help you choose the best solution for your home.

Most cooling systems rely on electricity to cool and heat homes, but certain gas-powered or propane air conditioners, use natural gas to power furnaces and run condensers in 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 within your gas furnace (if you have one) or inside an air handler in the event that you don’t have. The evaporator is the place where the refrigerant liquid is transformed into gas and absorbs heat from the home’s indoor air.

The evaporator consists of one or more copper coils tightly bonded. The refrigerant is able to reach the coils at low pressure, which makes it easier to transfer heat when it evaporates into gaseous form.

A fan blows the warm air from your home to the coil that is used to evaporate. The air is then cooled as heat is taken away from the evaporator. This reduces the temperature of the air inside. The cooled air then moves through your home’s ductwork system to each room which is where it circulates until it returns to the air conditioning system through return ducts.

The evaporator, in contrast to the compressor, requires to raise the boiling point of the refrigerant down to a low temperature to allow for effective air cooling. The evaporator also has its own fans to help it in achieving this objective.

The evaporator metering device makes sure that the refrigerant used in the liquid remains at the same level. The low-side floating is designed to open if there is no liquid in the evaporator. It will close when liquid enters the coils.

There are two kinds of evaporators: cases and uncased. The most commonly used type of evaporator in your home is a cased model. It’s enclosed inside the metal casing that protects your air conditioning unit. Uncased evaporators resemble the cased evaporators, however they don’t have an outer shell that is protected.

Both evaporators share the same purpose but it’s crucial to select the one that will satisfy your home’s particular needs. Some models are better suited for extreme environments, whereas others might be more appropriate for milder conditions. Consider how easy it is to clean and maintain your evaporator. This can save you time, money and hassle.

Condenser

Condensers are one of the three primary components of your home’s cooling system. They help it work efficiently. It is located outside of the home, and is connected to the evaporator coil via refrigerant lines. It is also home to a series of metal fins and fans that remove heat from the refrigerant gas that has been transported here from the evaporator. The heat that is removed helps the refrigerant to reduce in temperature and then transform to liquid form.

A compressor is connected to the condenser unit. It is used to pressurize low-pressure liquid refrigeration that has been pumped out of the evaporator coil. The compressor’s squeeze action increases the temperature, which is then transferred to the condenser unit to absorb the heat that is trapped in the air. After it has completed its cooling cycle, the refrigerant is pushed back into the compressor, where it is pressurized again before being pumped to the evaporator coil where the process begins again.

Because the condenser is located outside, it is exposed to the elements. Debris, such as twigs grass clippings, leaves and roofing shingles too can be thrown into the condenser unit, causing damage to it. By adding an universal HVAC condenser cover to your cooling and heating system can help to protect the equipment from damage when it’s not in use.

It is also crucial to not shade the condenser. This can reduce air flow, which can force the compressor to work harder to cool your home. This could result in higher energy bills as well as a loss of refrigerant.

Regular maintenance of your HVAC system can help ensure that the condenser is operating properly. Regularly having a professional technician inspect all major components of your HVAC system can assist in avoiding major problems. A professional service team can prevent problems by regularly checking the refrigerant levels. By following these steps, you’ll be able to prolong the lifespan of your heating and cooling system and reduce the cost of energy.

Compressor

A compressor is the core of your air conditioning unit, and it circulates refrigerant throughout the system to keep everything cool. It is like the blood that flows through your body when it pumps coolant between the evaporator coils and condenser. If something is wrong with the compressor, it will prevent the evaporator and condenser from completing their tasks and will leave your home feeling uncomfortable warm.

There are a variety of types of HVAC compressors. Each comes with its own advantages and disadvantages. A reciprocating compressor, for example it has a piston that moves upwards and downwards in the cylindrical. This creates a suction that draws in refrigerant. As the piston moves downwards, it reduces gas volume. A discharge valve opens to let the pressurized refrigeration into the condenser.

This type of compressor is equipped with a clutch and a crankshaft that helps the piston compress air. A Rotary compressor, on the other side, has blades within the cylinder that assist in helping compress the air. This kind of compressor is quiet, which makes it a popular option for residential use.

Both kinds of HVAC compressors are designed to raise the temperature of the refrigerant’s liquid while it is compressed, so that the vapor that exits the compressor is high-temperature and high-pressure. It is normal for heat to flow from high-temperature substances down to lower temperature substances and the hot vapor will travel to the evaporator and return to its liquid state.

While you can’t prevent the possibility of having a problem with your compressor, you can prevent the majority of AC problems by keeping track of your maintenance schedule. This will ensure that your equipment will last for many years, and it will give you peace of mind knowing that your home is always in good condition. If you do experience a problem with the compressor then your Griffith Energy Services technician can help you decide what repair options are best for you.

Thermostat

The thermostat is your heating and cooling system’s brain, and it decides the frequency and manner in which the system turns on and off. It measures the temperature of the air and compares it to a preset desired level. The thermostat will send a signal to adjust the temperature if off by a few degrees. The majority of modern thermostats utilize an electronic sensor known as a thermistor to gauge the temperature. The thermistor is made up of two metals which expand differently when heated up and cause the metals to bend in an opposite direction. When the thermistor reaches the temperature that it is set it sends a signal to the circuit board that your heating or AC should be turned on.

The touchscreens on newer models make it easy to program and operate. They are often programmed to automatically heat or cool your home at certain time frames, which avoids the hassle of having to set it each day. Additionally, they offer reports on energy usage so you can learn how to cut down on expenses.

If you have an older electromechanical model, the method of operation is a little more complex. It is made up of a bimetallic strip that is bonded to a vial by mercury. When the temperature changes in the vial, it causes the mercury in the vial to shift and complete or interrupt an electrical circuit. When the vial tips the thermostat, it turns on the cooling and heating system.

To ensure that your thermostat is in good condition, you must be sure to clean it on a regular basis to remove any dust that has built up. You should also make sure that it is not loose or bent. In certain cases, the thermostat’s readings may be incorrect due to a dirty or damaged evaporator coil. In this case, you will need to call a professional to fix it. If the issue is something else, like a blank screen, you can try changing the batteries or making sure that your breaker hasn’t been activated. This is a great example of how you can make your HVAC system more efficient by gaining knowledge about it and maximizing its use.
