What Are the Main Parts of Your Heating Air Conditioning Unit?
It may be worth investing in a replacement unit in the event that your home’s air conditioner is old and in need of repairs. A residential HVAC professional can help you determine the best solution for your needs.
Most cooling systems rely on electricity to cool and heat homes, but some, called gas-powered or propane air conditioners, utilize natural gas to fuel furnaces and operate condensers in a split system.
Evaporator
The evaporator coil in your air conditioner is the one that cools your home. The evaporator coil is in a container that is attached to or within your gas furnace (if you have one) or in an air handler, in the absence of. The evaporator is the place where the refrigerant is transformed into a liquid, and absorbs heat in your home’s air.
The evaporator consists of a few coils of copper that are tightly packed together. The refrigerant reaches the coils at low pressure, which makes it easier to transfer heat as it evaporates into gaseous state.
A fan blows warm air from your home over the coil that is used to evaporate. This air is cooled as heat is taken away from the evaporator. This reduces the temperature of the air inside. The cooled air is then circulated through the ductwork in your home to each room.
Contrary to the compressor, which requires to create refrigerant gas in high temperatures to ensure efficient cooling, the evaporator needs to bring its boiling point to a lower temperature for effective air cooling. The evaporator also uses its own fans to help it achieve this objective.
The evaporator metering device ensures that the refrigerant in the liquid is always at a constant level. The low-side floating is designed to be open when there is no liquid in the evaporator and close when liquid gets into the coils.
There are two main types of evaporators: cased and uncased. A cased evaporator is one you’ll likely to find in your home since it is enclosed inside the metal casing of your air conditioning unit. Uncased evaporators are similar, except it doesn’t have the outer shell that protects it.
While both evaporators serve the same purpose, it’s important to choose a model that’s suitable for the specific requirements of your home. Some models are better suited for more harsh environments, while others could be better suited to milder conditions. Also, you should think about how easy it will be to clean and maintain the evaporator, as this could save you time, money, and hassle in the long time.
Condenser
The condenser is among the three major components of your home’s air conditioning system that helps keep it operating efficiently. The condenser is situated outside the house and connected to the evaporator via refrigerant pipes. It has metal fins and fans that help to remove heat from the refrigerant which is being transported from the evaporator. The heat removed from the refrigerant gas helps it to cool and turn back into liquid form.
A compressor is connected to the condenser unit. It is used to pressurize the low-pressure liquid refrigerant that has been transferred from the evaporator. 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 is moved into the compressor to be pumped under pressure before being sent back to the evaporator coil.
Since the condenser is outdoors, it is susceptible to the elements. Debris like twigs, leaves, grass clippings and roofing shingles too can get into the condenser unit and damage it. A universal HVAC condenser can shield your heating and cooling equipment from damage while not in use.
It is also crucial to not shade the condenser. This can reduce air flow, which can force the compressor to work harder in order to cool your home. This could result in higher energy bills and a potential loss of refrigerant.
Regular maintenance of your HVAC system will ensure that the condenser works properly. A professional service technician examine all the major components of your system on a regular basis can aid in preventing major problems from occurring. A professional service team can avoid problems by checking regularly the refrigerant levels. Follow these steps to prolong the life of your cooling and heating system and cut down on energy costs.
Compressor
A compressor is the core of your air conditioning unit and it circulates refrigerant throughout the system to keep it cool. It’s like the blood in your body, pumping coolant between the evaporator coils and condenser. If something goes wrong with your compressor, it will stop the condenser and evaporator from doing their job and will leave your home warm and uncomfortable.
There are many different types of HVAC compressors. Each one comes with its own advantages and disadvantages. For example the reciprocating compressor is comprised of a piston that moves up and down within the cylinder. This motion creates suction that draws in the refrigerant. As the piston is moved down, it reduces the gas volume, and the discharge valve opens to let the refrigerant that is pressurized out into the condenser coil.
This type of compressor also comes with a clutch and a crankshaft, which helps the piston to compress air. A Rotary compressor, on other side, has blades within the cylinder that assist in helping compress the air. This kind of compressor is very quiet, making it a popular choice for residential applications.
Both kinds of HVAC compressors are designed to raise the temperature of the refrigerant liquid when it is compressed, so that the vapor that exits the compressor is high-pressure and high-temperature. The heat naturally flows from high-temperature substances down to lower temperatures which is why the hot vapor moves to the evaporator before returning to its liquid state.
While you can’t prevent the possibility of having a problem with your compressor, you can avoid the majority of AC issues by staying on top of your maintenance schedule. This will ensure that your AC will last for a long time and give you peace-of-mind knowing that your home will remain comfortable.

Thermostat
The thermostat is the brain of your cooling and heating system, allowing it to regulate the timing and manner in which it is turned on and off. It measures the temperature of the air and compares it with a preset desired level. If it is off by just a few degrees the thermostat will send an electronic signal to bring it towards the desired temperature. The majority of modern thermostats gauge temperature using a digital sensor known as a thermosistor. The thermistor consists of two different metals that expand at different rates when they warm up and cause them to bend in opposite directions. When the thermistor reaches its temperature set, it signals the circuit board to switch on your heating or AC system.
The touchscreens on newer models make it easier to program and operate. Many thermostats are programmed to automatically cool and heat your home at specific times. This saves you from having to manually set them each day. They also provide information on energy consumption so you can discover ways to reduce costs.
If you have an older electromechanical model the method of operation is a little more complex. It is made up of a bimetallic ring that is bonded to mercury a vial. When the temperature changes and the mercury inside a vial moves, either complete or rupturing an electrical circuit. When the vial tilts the thermostat, it activates the cooling and heating system.
To keep your thermostat in good condition, you must be sure to clean it on a regular basis to remove any dust that has accumulated. You must also ensure that it’s not tangled or unbalanced. In certain cases, the thermostat’s readings may be incorrect due to a dirty or damaged evaporator coil. If that is the case, you will require a professional to fix it. If the problem is something else, such as blank screens it is possible to try changing the batteries or ensuring that the breaker hasn’t been activated. This is an example of how your HVAC system can be more efficient if you make the effort to learn about it and make the most of its use.
