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 repair. A residential HVAC expert can assist you in selecting the best option for your home.

Most cooling systems rely upon electricity to cool and heat homes, however certain propane or gas-powered air conditioners, use natural gas to power furnaces and run condensers within a split system.

Evaporator

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

The evaporator has one or more copper coils tightly packed. The refrigerant is at low pressure as it reaches the coils, making it easier to transfer heat.

A fan blows your home’s warm indoor air over the evaporator coil. The air is then cooled through 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 is then circulated through the ductwork of your home, and then to each room.

The evaporator, in contrast to the compressor, requires to raise the boiling point of the refrigerant to a low temperature to ensure efficient air cooling. The evaporator also has its own fans to help it in achieving this goal.

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

There are two kinds of evaporators: noncased and cased. A cased evaporator is the one you’re most likely to see in your home, since it’s enclosed within the metal casing of your air conditioning unit. An uncased evaporator is similar however it doesn’t come with the protective outer shell.

While both evaporators serve the same purpose, it’s important to select one that is able to meet the specific requirements of your home. For instance, some models are better suited to extreme working environments, while others are better suited to more moderate conditions. Think about how easy it is to clean and maintain your evaporator. This can save you money, time and effort.

Condenser

Condensers are among the three primary components of the cooling system in your home. They help it work efficiently. It is located outside of the home, and is connected to the evaporator’s coil by refrigerant lines. It also houses an array of metal fins and fans which work to eliminate heat from the refrigerant gas which has been transferred from the evaporator. The heat removed allows the refrigerant to be cooled and transform into a liquid state.

A compressor is connected to an condenser unit. It works to pressurize low-pressure liquid refrigeration that has been pumped out of the evaporator coil. The compressor’s squeeze action increases the temperature, and it is carried into the condenser to absorb the heat that is trapped in the air. After it has completed its cooling process and the refrigerant is pumped back into the compressor where it is again pressurized before being pumped into the evaporator coil, where the process starts all over again.

Since the condenser is outdoors, it is vulnerable to the elements. Debris, such as twigs grass clippings, leaves and even roofing shingles can be thrown into the condenser unit and damage it. Adding an universal HVAC condenser cover to your heating and cooling system can help to protect the equipment from accidental damage when it’s not in use.

Do not shade the condenser. This can decrease air flow, which can force the compressor to work harder to cool your home. This could lead to more energy costs and a possible loss of refrigerant.

Regular maintenance will ensure that your HVAC system is working properly. A professional service technician look over every major component of your system on a regular basis will assist in preventing any major problems from occurring. In addition having a professional service team check your refrigerant levels regularly can help avoid any issues from arising. Follow these simple steps to help extend the life of your cooling and heating system and lower your energy costs.

Compressor

The compressor is the core of your air conditioner. It circulates refrigerant through the system, which keeps everything cool. You can think of it like the blood in your body, as it circulates coolant back and forth between your evaporator and condenser coils. If something goes 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. A reciprocating compressor, as an example, has a piston moving up and down in a cylindrical. This movement creates a suction which draws in refrigerant. As the piston moves downward, it reduces gas volume. A discharge valve opens to release the pressurized refrigeration to the condenser.

This type of compressor is equipped with a clutch, and a crankshaft that aids the piston compress air. A Rotary compressor, on the other hand, has blades inside the cylinder which help compress the air. This type of compressor is very quiet, which makes it a popular option for residential applications.

Both types of HVAC compressors are designed to raise the temperature of the liquid refrigerant when it is compressed, so that the vapor that exits the compressor is high-temperature and high pressure. Heat naturally flows from high-temperature materials down to lower-temperature substances which is why the hot vapor will move to the evaporator before returning to its liquid state.

You can avoid the majority of AC issues by keeping up with 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 at ease.

Thermostat

The thermostat is the brains of your heating and cooling system, which allows it to decide when and how it is turned on and off. It compares the air temperature to a pre-set level. If it is off by a few degrees the thermostat will send an electronic signal to bring it closer to the desired temperature. The majority of modern thermostats gauge temperature with a digital sensor known as the thermosistor. The thermistor is composed of two different metals that expand at different rates when they get hot and bend in opposite directions. When the thermistor is at its temperature it tells the circuit board to turn on your heating or AC system.

Newer models of thermostats have touchscreens that make them easy to operate and program. Many thermostats are programmed to automatically heat and cool your home at specific times. This saves you from having to set them manually each day. They also provide reports on energy consumption so you can learn ways to reduce costs.

If you have an older electromechanical model the way that it works is a bit more complicated. It consists of a bimetallic strip which is attached to a vial using mercury. When the temperature fluctuates in the vial, it causes the mercury inside the vial to shift, completing or interrupting 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 working condition, you must clean it frequently to get rid of any dust that has built up. Also, make sure that it is not crooked or loose. In some cases the thermostat’s readings might be incorrect due to a damaged or dirty evaporator coil. If that is the situation, you’ll need to call a professional to fix it for you. If the issue is something else, like a blank screen it is possible to try changing the batteries or making sure that the breaker hasn’t been tripped. This is an illustration of how your HVAC system can be more efficient if you make the effort to research it and optimize its use.
