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

If the air conditioning in your home is at its peak, high repair costs and energy bills may make it worth investing in a new unit. A residential HVAC expert can help you choose the best option for your home.

The majority of 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 in a split system.

Evaporator

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

The evaporator consists of a few copper coils that are tightly packed. The refrigerant is at low pressure when it reaches the coils, making it easier to transfer heat.

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

Contrary to the compressor, which needs to produce refrigerant gas at extremely high temperatures to ensure efficient cooling, the evaporator requires it to bring its boiling point to a lower temperature for effective air cooling. The evaporator has its own fans in order to achieve this objective.

The evaporator metering system ensures that the refrigerant in the liquid remains at a constant level. The float on the low-side is designed to be open when there’s no liquid in the evaporator, and closes when it detects liquid entering the coils.

There are two kinds of evaporators: noncased and cases-based. A cased evaporator is one you’ll most likely to see in your home, since it’s contained within the metal casing of your air conditioning unit. An uncased evaporator is similar, except it doesn’t have the outer shell that protects it.

While both evaporators serve the identical purpose, it’s vital to choose a model that’s able to meet the specific requirements of your home. For instance, certain models are more suited to extreme working environments, while others are better suited to milder conditions. Think about how easy it is to clean and maintain your evaporator. This can help you save time, money and hassle.

Condenser

Condensers are one of the three primary components of your home’s cooling system. They help it work efficiently. The condenser is situated outside the house and connected to the evaporator by refrigerant pipes. It has fans and metal fins which help to remove heat from the refrigerant which has been transported from the evaporator. The heat removed from refrigerant gas helps it to 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 was taken from the evaporator coil. The compressor’s squeeze action increases the temperature, and it is passed into the condenser to absorb the heat that is trapped in the air. Once the cooling cycle is complete the refrigerant will be introduced into the compressor to be pressurized prior to being pumped back to the evaporator coil.

The condenser unit is exposed elements since it is outside. Leaves and twigs grass clippings, grass clippings, or even roofing shingles, can cause damage to the condenser. By adding an universal HVAC condenser cover to your cooling and heating system can help protect the equipment from damage when it isn’t in use.

It is also important to avoid shading the condenser. Shades can limit air flow and force the compressor to work harder to cool your home. This can lead to more expensive energy bills and a potential loss of refrigerant.

Regular maintenance of your HVAC system can help ensure that the condenser is working effectively. Having a professional service technician look over every major component of your system regularly can assist in preventing any major issues from arising. A professional service team can also avoid problems by checking regularly the refrigerant levels. By following these easy steps, you’ll be able to extend the longevity of your cooling and heating system and lower your energy costs.

Compressor

The compressor is the core of your air conditioner. It circulates refrigerant throughout the system, ensuring that everything stays cool. You can think of it as the blood flowing through your body, in that it moves coolant between the condenser and evaporator coils. If the compressor fails, the evaporator will not be able perform its job and your house will get extremely hot.

There are many different types of HVAC compressors, and each one has distinct advantages and disadvantages. A reciprocating compressor, as an example it has a piston that moves upwards and downwards within the cylinder. This movement produces a suction that draws in refrigerant. As the piston moves downward, it reduces gas volume. A discharge valve then opens to let the pressurized refrigeration to 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 hand, has blades inside the cylinder which help compress the air. This type of compressor is extremely quiet, making it a popular option for homes.

Both types of HVAC compressors are designed to raise the temperature of the refrigerant liquid when it is compressed, ensuring that the vapor which exits the compressor is high-pressure and high-temperature. The heat naturally flows from high-temperature substances down to lower-temperature substances, so the hot vapor will travel to the evaporator and return to its liquid state.

You can avoid most AC problems by keeping up with your maintenance schedule. This will ensure that your equipment will last for years and give you peace-of-mind knowing that your home will remain comfortable. Griffith Energy Services can help you determine the best repair options should you have a compressor issue.

Thermostat

The thermostat is your heating and cooling system’s brain and it determines the time and frequency at which the system is turned on and off. It compares the temperature of the air to a pre-set desired level. If it is off by a few degrees it will send an electronic signal to alter it towards the desired temperature. The majority of modern thermostats measure temperature with the digital sensor, also known as the thermistor. The thermistor consists of two metals that expand in different ways when heated which causes the metals to bend in opposite direction. When the thermistor reaches the temperature that it is set it informs the circuit board that heating or AC should be turned on.

Modern thermostats come with touchscreens that make them simple to use and program. They are often programmed to automatically cool or heat your home at certain times, which saves you the effort of having to manually set it every day. They also provide reports on energy consumption so that you can find ways to cut costs.

If you have an older electromechanical model, the method of operation is a bit more complex. It is made up of a bimetallic strip which is bonded to a vial using mercury. If the temperature changes it causes the mercury in the vial to move in a way, interrupting or completing an electrical circuit. When the vial is tipped it triggers the thermostat to turn on the cooling or heating system.

To ensure that your thermostat is in good condition You must clean it regularly to remove any dust that has accumulated. Also, make sure that it isn’t bent or loose. In some instances, the thermostat’s readings could be inaccurate due to a damaged or dirty evaporator coil. In this situation, you’ll have to contact an expert to fix it. If you’re experiencing other issue, like blank displays, try changing your batteries or checking that your breaker is not tripped. This is an example of how your HVAC system can be more efficient when you take the time to research it and improve its use.
