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 choosing 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

An evaporator coil is the part of your air conditioner that cools your home. The evaporator can be found in a box connected to your gas furnace or inside it (if you own one). If you don’t have one, the coil can be found inside an air handler. The evaporator is the place where the refrigerant liquid turns into a gas and absorbs heat from the home’s indoor air.

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

A fan blows warm indoor air over the coil of the evaporator. The air is cooled by the removal of heat from the evaporator which alters the refrigerant’s temperatures and reduces the temperature of your home’s air. The cooled air then moves through the ductwork of your home to each room which is where it circulates until it returns to the air conditioning system through return ducts.

The evaporator, unlike the compressor, requires to raise the boiling point of the refrigerant to a lower temperature to achieve effective air cooling. The evaporator makes use of its own fans to accomplish this final goal.

The evaporator metering device ensures that the refrigerant used in the liquid remains at the same level. The low-side floating is designed to open when there is no liquid in the evaporator, and close when liquid enters the coils.

There are two kinds of evaporators: cased and noncased. The most commonly used kind of evaporator you can find in your home is the one that is cased. It’s enclosed inside the metal casing that protects the air conditioning unit. Uncased evaporators resemble cased evaporators, but they do not have an outer shell with protection.

Both evaporators serve the same purpose but it’s important to select one that is able to meet the specific requirements of your home. Some models are more suited to extreme environments, while others may be more suitable in milder conditions. Think about how easy it would be to clean and maintain your evaporator. This can help you save time, money and effort.

Condenser

The condenser is one of three primary parts of your air conditioning system that help keep it working efficiently. The condenser is situated outside the house and connected to the evaporator by refrigerant pipes. It contains metal fins and fans which help to remove heat from the refrigerant that was transported from the evaporator. The heat that is removed from the refrigerant gas aids it cool before turning back into liquid form.

A compressor is connected to the condenser unit. It helps to pressurize the low pressure liquid refrigerant that has been transferred from the evaporator. The compressor’s squeezing action increases the temperature, which is passed into the condenser to absorb latent heat in the air. After it has completed its cooling cycle the refrigerant is then pushed back into the compressor, where it is pressed again prior to being pumped to the evaporator coil where the process begins all over again.

The condenser unit is exposed elements since it is outside. Debris, such as twigs leaves, grass clippings and roofing shingles may fall into the condenser unit and damage it. A universal HVAC condenser can protect your heating and cooling equipment from damage while not in use.

Beware of shading the condenser. Doing so can restrict air flow and force the compressor to work harder to cool your home. This can lead to increased energy costs as well as a loss of refrigerant.

Regular maintenance of your HVAC system will help to ensure that the condenser is operating effectively. Having a professional service technician inspect every major component of your system on a regular basis can assist in preventing any major issues from arising. Additionally having an expert service team examine the refrigerant levels on a regular basis can also help to keep any problems from developing. Follow these steps to help extend the life of your cooling and heating system and cut down on energy costs.

Compressor

A compressor is the center of your air conditioning unit, and it circulates refrigerant throughout the system to keep it cool. It is as the blood flowing through your body, as it moves the coolant back and forth between your condenser and evaporator coils. If something is wrong with the compressor, it will prevent the condenser and evaporator from completing their tasks and leave your home warm and uncomfortable.

There are many different types of HVAC compressors, and each one has its own pros and cons. For example the reciprocating compressor features an engine that moves up and down within the cylinder. This movement creates suction that 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 is equipped with a clutch and a crankshaft that helps the piston compress air. A rotary compressor has blades inside the cylinder to assist in compressing the air. This type of compressor is very quiet, which makes it a popular option for residential applications.

The HVAC compressors of both types are designed to increase the temperature of the liquid while it is compressed. This results in the formation of a high-temperature, high pressure vapor. Since heat naturally flows from higher-temperature substances to lower-temperature ones, the hot vapor will flow into the evaporator coils before it can transform back to its original liquid state.

You can prevent most AC problems by keeping up with your maintenance schedule. This will ensure that your equipment will last for a long time, and it will give you peace of mind knowing that your home is always comfortable. If you do experience problems with your compressor, your Griffith Energy Services technician can help you decide what repair options are best for you.

Thermostat

The thermostat is the brain of your heating and cooling system, allowing it to control the timing and manner in which it turns on and off. It determines the temperature of the air and compares it with an established desired level. If it is off by a few degrees, the thermostat will send an electronic signal to alter it closer to the desired temperature. The majority of modern thermostats measure temperature by using the digital sensor, also known as a thermosistor. The thermistor consists of two metals which expand differently when heated up, causing the metals to bend in an opposite directions. When the thermistor is at the temperature that it is set it sends a signal to the circuit board that heating or AC should be switched on.

The touchscreens on newer models make it easy to program and operate. Many thermostats can be programmed to automatically cool and heat your home at certain times. This will save you from having to set them manually every day. They also provide information on energy consumption so that you can discover ways to reduce expenses.

If you have an older electromechanical model, the method of operation is a little more complex. It is composed of a bimetallic band which is bonded to mercury a vial. If the temperature changes it causes the mercury in the vial to tilt in a way, interrupting or completing 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 to get rid of dust. Also, make sure it isn’t bent or loose. In certain cases the thermostat could be having trouble in its readings due to an unclean evaporator coil or the thermistor being damaged. In this scenario, you’ll need to call an expert to fix the problem for you. If you’re experiencing a different issue, for instance a blank display, try changing your batteries or making sure whether your breaker has not tripped. This is a good illustration of how you can improve the efficiency of your HVAC system more efficient by gaining knowledge about it and maximizing its use.
