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

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

Gas-powered air conditioners, also referred to as propane air conditioners, make use of natural gas to heat and running condensers.

Evaporator

The evaporator coil in your air conditioner is what cools your house. The evaporator coil is located in a box attached to or inside your gas furnace (if you have one) or in an air handler, in the absence of. The evaporator is the place where the refrigerant turns into a liquid and then absorbs heat from the air in your home.

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

A fan blows your home’s warm indoor air over the evaporator coil. This air is cooled as heat is removed from the evaporator. This lowers the temperature of your indoor air. The cooled air is circulated through the ductwork of your home to each of the rooms.

Unlike the compressor, which requires to create refrigerant gas at extremely high temperatures to ensure efficient cooling, the evaporator only needs to bring its boiling point to a lower temperature to allow for efficient air cooling. The evaporator also uses its own fans to help to achieve this final goal.

The metering device of the evaporator assists to ensure that the refrigerant is at the same amount of liquid within it. The low-side floating is designed to open when there is no liquid in the evaporator. It will close when liquid is introduced into the coils.

There are two kinds of evaporators: noncased and cased. The most common type of evaporator that you will find in your home is the cased one. It is housed inside the casing made of metal that covers your air conditioning unit. Uncased evaporators are similar to the cased evaporators, however they don’t have a protective outer shell.

Although both evaporators serve the same purpose, it’s crucial to select a model able to meet the specific requirements of your home. Certain models are more suited to extreme environments, while others may be more suitable in milder conditions. Also, you should consider how easy it will be to clean and maintain the evaporator, as this can save you time, money and hassle in the long time.

Condenser

Condensers are one of the three major components of your cooling system. They help it work efficiently. The condenser is outside the home and is connected to the evaporator by refrigerant pipes. It is comprised of metal fins and fans that help remove heat from the refrigerant which has been transferred from the evaporator. The heat that is removed from the refrigerant gas allows it to cool and turn back into liquid form.

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

Since the condenser is outside, it is exposed to the elements. Debris such as leaves or twigs grass clippings or roofing shingles, can cause damage to the condenser. By adding the universal HVAC condenser cover to your heating and cooling system can help to protect the equipment from accidental damage even when it’s not in use.

It is also important to not shade the condenser. Doing so can restrict air flow and force the compressor to work harder to cool your home. This could lead to increased energy costs and possibility of losing refrigerant.

Regular maintenance will ensure that your HVAC system is running efficiently. Regularly having a professional technician check every major component of your HVAC system will aid in preventing major issues. Additionally having a professional service team check your refrigerant levels frequently can also help to keep any problems from developing. By following these simple steps, you will be able to extend the lifespan of your cooling and heating system and lower your energy bills.

Compressor

The compressor is the heart of your air conditioning. It circulates refrigerant throughout the system, which keeps everything cool. It’s like the blood in your body, since it circulates coolant between the condenser and evaporator coils. If something is wrong with the compressor, it will stop the condenser and evaporator from completing their tasks and will make your home uncomfortably warm.

There are several different kinds of HVAC compressors, and each one has distinct advantages and disadvantages. A reciprocating compressor, as an example, has a piston moving up and down in the piston. This creates a suction that draws in the refrigerant. When the piston is moving downwards it decreases the volume of gas. A discharge valve opens to release the pressurized refrigeration into the condenser.

This type of compressor is also equipped with a clutch and a crankshaft which helps the piston to 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 very quiet, which makes it a popular choice for homes.

Both kinds of HVAC compressors are designed to increase the temperature of the refrigerant liquid while it is compressed, ensuring that the vapor which exits the compressor is high-pressure and high-temperature. Since heat naturally flows from higher temperature substances to those with lower temperatures, the hot vapor is able to move into the evaporator coils and return to its original liquid state.

You can avoid the majority of AC issues by staying on top with your maintenance schedule. This will ensure that your equipment will last for years and provide you with 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 repair options are best for you.

Thermostat

The thermostat is your heating and cooling system’s brain, and it controls the time and frequency at which the system turns on and off. It measures the temperature of the air and compares it with an established desired level. The thermostat will send an indication to alter the temperature if off a few degrees. The majority of modern thermostats employ the digital sensor, also known as the thermistor, which measures the temperature. The thermistor is made up of two metals that expand in different ways when heated up, causing the metals to bend in opposite directions. When the thermistor reaches the temperature it was set to it sends a signal to the circuit board that your heating or AC should be switched on.

The touchscreens on the latest models make it easy to program and operate. They are often programmed to automatically cool or heat your house at specific times, which saves you the headache of manually setting the temperature each day. Additionally, they offer information on energy usage so you can learn how to reduce expenses.

If you have an older electromechanical model, the way it operates is a little more complex. It is made up of a bimetallic ring that is bonded with mercury to a vial. If 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 is tilted, it triggers the thermostat to turn on the cooling or heating system.

You must regularly clean your thermostat in order to eliminate dust. Also, make sure that it isn’t bent or loose. In some cases the thermostat could be experiencing issues with its readings due to a dirty evaporator coil or the thermistor being damaged. In that scenario, you’ll require an expert to fix it. If you are experiencing a other issue, like a blank display Try changing your batteries or checking that your breaker is not in a state of being tripped. This is a good illustration of how your HVAC system can be more efficient if you spend the time to understand it and optimize its use.
