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

It may be worth investing in a replacement unit when your home’s HVAC is old and in need of repairs. A residential HVAC expert can assist you in selecting the right option for your home.

Gas-powered air conditioners, also referred to as propane air conditioners, use natural gas for heating and condensers that run.

Evaporator

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

The evaporator consists of one or more coils of copper that are tightly packed. The refrigerant enters the coils with low pressure, which makes it easier for it to transfer heat when it evaporates into gaseous form.

A fan blows your home’s warm indoor air over the coil of the evaporator. This air is cooled as heat is removed from the evaporator. This reduces the temperature of the air inside. The cool air then flows through your home’s ductwork to every room which is where it circulates until it is returned to the air conditioning system via return ducts.

Contrary to the compressor, which needs to make the refrigerant gas at extremely high temperatures to ensure efficient cooling, the evaporator requires it to raise its boiling point to a low temperature for effective air cooling. The evaporator also uses its own fans to help it in achieving this goal.

The metering device in the evaporator helps to ensure that the refrigerant has an even 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 types of evaporators: cased and uncased. A cased evaporator is the one you’re most likely to find in your home since it’s contained within the metal casing of your air conditioning unit. Uncased evaporators are similar but it doesn’t have the outer shell that protects it.

Both evaporators serve the same purpose, however it is important to choose one that is able to meet your home’s specific needs. For example, some models are more suited to more harsh working environments, whereas others are better suited for more moderate conditions. Consider how easy it is to clean and maintain your evaporator. This could help you save time, money and effort.

Condenser

Condensers are among the three primary components of your home’s cooling system. They help it work efficiently. It is located outside of the house, connected to the evaporator coil by refrigerant lines. It is also home to an array of fans and metal fins that remove heat from the refrigerant gas that has been transported here from the evaporator. The heat removed from refrigerant gas aids it cool and turn back into liquid form.

A compressor is attached to an condenser unit. It works to pressurize low-pressure liquid refrigeration that is pumped out of the evaporator coil. The squeezing action of the compressor increases the temperature of the coolant, which then flows into the condenser coils to absorb heat that is not being released from the air around it. After it has completed its cooling cycle, the refrigerant is pushed back into the compressor, where it is pressurized again before being pumped into 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 too can be thrown into the condenser unit, causing damage to it. A universal HVAC condenser will protect your heating and cooling equipment from damage when it is not in use.

Do not shade the condenser. This can impede air flow and make the compressor work harder to cool your home. This could lead to increased energy costs and possible loss of refrigerant.

Regular maintenance of your HVAC system will help to ensure that the condenser is working properly. A professional service technician inspect all of the major components of your system regularly can assist in preventing any major issues from arising. In addition 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’ll be able to extend the life of your cooling and heating system as well as reduce your energy bills.

Compressor

A compressor is the heart of your air conditioning unit, and it circulates refrigerant through the system to keep everything cool. It’s as the blood flowing through your body, since it moves the coolant between your condenser and evaporator coils. If the compressor fails then the evaporator won’t be able to do its job and your home will be extremely hot.

There are a myriad of different kinds of HVAC compressors. Each has its own benefits and drawbacks. A reciprocating compressor, for instance, has a piston moving upwards and downwards in the piston. This creates a suction that draws in the refrigerant. As the piston is moved down it decreases the gas volume, and then a discharge valve is opened to let the refrigerant that is pressurized out into the condenser coil.

This type of compressor also includes a clutch and a crankshaft, which helps the piston to compress the air. A Rotary compressor, on the other side, has blades within the cylinder that help to compress the air. This type of compressor is quiet, which makes it an ideal choice for residential applications.

Both types of HVAC compressors are designed to raise the temperature of the refrigerant liquid when it is compressed, ensuring that the vapor that exits the compressor is high-pressure and high-temperature. Since heat naturally flows from high-temperature substances to lower temperature ones, the hot vapor is able to move into the evaporator coils before it can transform back to its original liquid state.

While you can’t avoid the possibility of having a problem with your compressor, you can stop the majority of AC issues by staying on top of your maintenance schedule. This will help your equipment last for a long time and will give you peace of mind knowing your home is always comfortable.

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 the desired temperature set by a preset. The thermostat will send an alert to adjust the temperature if it is off by a few degrees. The majority of modern thermostats measure temperature with the digital sensor, also known as the thermosistor. The thermistor is comprised of two metals that expand in different ways when heated up, causing the metals to flex in an opposite direction. When the thermistor reaches the temperature set it informs the circuit board that your heating or AC should be switched on.

The touchscreens on newer models make it easy to program and operate. They are often programmed to automatically heat or cool your house at specific times, which eliminates the effort of having to manually set the temperature each day. They also provide information on energy consumption so you can learn ways to reduce expenses.

If you have an older electromechanical model, the way it operates is a bit more complicated. It is comprised of a bimetallic strip that is bonded to a vial with mercury. If the temperature changes in the vial, it causes the mercury inside the vial to move, completing or interrupting an electrical circuit. When the vial tipping, the thermostat turns on the cooling and heating system.

It is essential to regularly clean your thermostat to remove dust. You must also ensure that it isn’t sagging or crooked. In some cases the thermostat’s readings may be inaccurate due to a damaged or dirty evaporator coil. If that is the case, you will need to call a professional to fix it for you. If you’re experiencing a different issue, for instance a blank display try replacing your batteries or checking that your breaker isn’t tripped. This is a good illustration of how you can make your HVAC system more efficient by learning about it and maximizing its use.
