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

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

Most cooling systems rely on electricity to cool and heat homes, but some, such as propane or gas-powered air conditioners, utilize natural gas to fuel furnaces and operate condensers in a split system.

Evaporator

The evaporator coil of your air conditioner is the one that cools your house. The evaporator coil is located in a container that is attached to or inside your gas furnace (if you have one) or in an air handler if you don’t. The evaporator is the place where the refrigerant turns into a liquid, and absorbs heat in your home’s air.

The evaporator is made up of one or more copper coils which are tightly packed. The refrigerant is in low pressure when it reaches the coils, which makes it easier to transfer heat.

A fan blows warm indoor air over the coil of the evaporator. This air is cooled by the removal of heat from the evaporator, which changes the refrigerant’s temperature and lowers your indoor air temperature. The cool air is circulated through the ductwork in your home to each of the rooms.

In contrast to the compressor, which requires to produce refrigerant gas in high temperatures to ensure efficient cooling, the evaporator needs to bring its boiling point to a low temperature for effective air cooling. The evaporator also has its own fans to help it achieve this final goal.

The metering device in the evaporator helps to ensure that the refrigerant maintains the same amount of liquid inside it. The low-side float is designed to open when there’s no liquid in the evaporator and closes when it sees liquid enter the coils.

There are two kinds of evaporators, noncased and cases-based. The most popular type of evaporator in your home is a cased model. It is housed inside the metal casing that protects your air conditioning unit. Uncased evaporators are similar to the cased evaporators, however they do not have an outer shell that is protected.

While both evaporators serve the same purpose, it’s important to choose a model that’s suitable for your home’s unique requirements. Certain models are more suited to more harsh environments, while others could be more suitable in more moderate conditions. Think about how easy it would be to clean and maintain your evaporator. This could save you time, money and hassle.

Condenser

The condenser is among the three primary parts of your air conditioning system which helps to keep it running 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 fans and metal fins that work to remove heat from the refrigerant gas that was transferred from the evaporator. The heat removed from the refrigerant gas aids it to cool and turn back into liquid form.

A compressor is connected to the condenser unit and works to pressurize the low-pressure liquid refrigerant that was pumped from the evaporator coil. The compressor’s squeezing action increases the temperature, which is then carried into the condenser to absorb latent heat in the air. After the cooling cycle the refrigerant is then pushed back into the compressor, where it is again pressurized before being pumped to the evaporator coil, where the process begins all over again.

The condenser unit is exposed to elements since it is outside. Debris such as twigs, grass clippings, leaves, and roofing shingles may fall into the condenser unit and damage it. The addition of the universal HVAC condenser cover to your heating and cooling system can help protect the equipment from accidental damage when it isn’t in use.

It is also important to avoid shading the condenser. This can reduce air flow, forcing the compressor to work harder to cool your home. This could result in higher energy bills and a potential loss of refrigerant.

Regular maintenance will ensure that your HVAC system is working properly. Regularly having a professional technician check all major components of your HVAC system can assist in avoiding major problems. Additionally, having a professional service team check your refrigerant levels regularly will also help prevent any problems from developing. Follow these easy steps to extend the life of your heating/cooling system and cut down on energy costs.

Compressor

The compressor is the core of your air conditioning. It pumps refrigerant through the system, keeping everything cool. You can think of it as the blood that circulates through your body, as it moves the coolant back and forth between the condenser and evaporator coils. If the compressor fails, the evaporator will not be able to perform its job and your house will be extremely hot.

There are many different 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 piston. This movement creates a suction which draws in refrigerant. As the piston is moved down, it reduces the volume of gas, then a discharge valve opens to let the refrigerant that is pressurized out into the condenser coil.

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

The HVAC compressors of both kinds are designed to raise temperatures of the liquid when it is compressed. This results in the formation of a high-temperature, high pressure liquid. The heat naturally flows from high-temperature materials down to lower temperature substances which is why the hot vapor will travel to the evaporator before returning to its liquid state.

You can avoid most AC issues by staying on top with your maintenance schedule. This will ensure that your equipment will last for a long time and it will provide you with peace of mind knowing that your home is always comfortable. If you do experience problems with your compressor or the compressor itself, 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 is turned on and off. It measures the temperature of the air and compares it to a preset desired level. If it is off by a few degrees the thermostat will send an electronic signal to alter it towards the desired temperature. The majority of modern thermostats measure temperature by using the digital sensor, also known as a thermosistor. The thermistor is comprised of two metals that expand differently when heated, causing the metals to flex in an opposite directions. When the thermistor reaches the temperature that it is set it informs the circuit board that your heating or AC should be switched on.

Modern thermostats come with touchscreens that make them simple to use and program. They can be programmed to automatically cool or heat your home at specific times, which saves you the headache of having to manually set it every day. In addition, they provide information on energy usage so you can learn how to reduce expenses.

If you have an older electromechanical model the way that it works is a little more complex. It is comprised of a bimetallic piece that is bonded to a vial using mercury. When temperatures change the mercury in the vial shifts, either completing or breaking a circuit. When the vial is tilted, it triggers the thermostat to turn on the cooling or heating system.

It is essential to regularly clean your thermostat to get rid of dust. You should also make sure that it isn’t sagging or unbalanced. In some cases the thermostat’s readings may be incorrect due to a dirty or damaged evaporator coil. If that is the case, you will need to call an expert to fix the problem for you. If the problem is something else, like blank screens it is possible to try changing the batteries or making sure that your breaker has not been activated. This is an example of how your HVAC system can be more efficient if you take the time to learn about it and improve its use.
