Air Conditioning Components – A Brief Guide

Air conditioners have been around for over a century. On hot, humid days, nothing is better than stepping from the outdoors into the cool of your home or business. Modern HVAC systems have evolved and are a critical part of any structure. It’s important for any homeowner or business owner to know something about air conditioning components before calling in the experts.

Get To Know Your Central Air Conditioning System

Most homes and businesses today have what is called a central HVAC system. This system is often called a split-system air conditioner. Part of the AC system is inside and can be found with your furnace. Part of the AC system is outside in the exterior AC unit itself.

All air conditioning units monitor and regulate the air temperature through a thermostat. AC systems also have filters that remove dust and particles that flow through the system as it circulates air. Air conditioning systems also act as dehumidifiers. What an AC system does best of all is not only regulate the temperature but also lessen humidity. This makes for a much more comfortable atmosphere.

Many components make up a central HVAC system, but four are critical to the running of your AC system. As a homeowner, you should be familiar with each.

Evaporator

The evaporator is located on the inside portion of an AC system. It receives liquid refrigerant that is turned into gas. This, in turn, cools and dehumidifies the air. The gas absorbs all of the heat and this is taken to the condenser.

Condenser

The condenser is located in the outside unit of the AC system. It works in conjunction with the evaporator. The hot, refrigerant gas is brought back to the condenser where the heat is ventilated and the refrigerant is turned back into liquid.

Compressor

The compressor works with the condenser to turn the refrigerant back into liquid. It is a big electric pump that is also located in the outside unit of your AC system. The compressor pressurizes the refrigerant gas, thus turning it back into liquid.

Expansion Valve

Working alongside the evaporator is the expansion valve. This part is usually located in-between the evaporator and the condenser. It has one function and that is to ascertain how much refrigerant is moving into the evaporator, where it then get turned into gas.

Knowing these four important air conditioning components will go a long way to recognizing when you have a problem and what you should do if your AC is not working properly. There are fixes that you can do on your own, and if this is a job for your local repairman, then you’ll know that, too. Never tinker with things you aren’t familiar with as this can be dangerous.

All air conditioning components should be checked yearly before you turn on your AC system for the season. When things go wrong, it may be a quick fix or it could signal that the entire system needs to be replaced.

There is no need for a powerful unit that can cool thousands of square feet of house, when your home is less than 2,000 square feet. If you are in need of a new AC system, you will find that it will be much more energy-efficient than the old one it is replacing. You will see that difference in your energy bills.

HVAC Considerations

For an HVAC installation service, the decision on the type of system to install is a joint decision by the engineer, contractor, architect and building owner. Before you think of the air conditioning system to install, consider the following:

  1. Type

You may choose a central air conditioning unit or a ductless air conditioning unit.

The central unit is popular. Central air conditioning components are:

  • An indoor air handler that has a blower connected to evaporation coils and an outside air condenser.
  • Another component of this unit is a ductwork installed in the entire building.
  • On the other hand, choose a ductless air conditioner if you want to avoid the cost of installing ductwork in the building. It consists of two units: one installed in the building and the other outside.
  1. Cost

Consider the cost of buying and installing the unit. If you plan to resell the building think of the value the air conditioning unit will add to it.

The unit should fit your initial estimated cost. An energy efficient air conditioning unit will be expensive, but in the long run you won’t pay high energy bills.

Factor in the cost of maintenance and repairs. Poor quality air conditioning units may turn into a hazard in your home. It may not last long and will cost more in repairs. The air conditioning components should be durable.

  1. Warranty

A good system must have a warranty. This gives you more of a financial safety net in case of a breakdown. A unit with air conditioning components of high quality attracts a longer warranty period as the manufacturer expects it to last long.

Understand the terms and conditions of the warranty to benefit from it. Some companies require you to use their contractors as part of their terms.

  1. Size

The size of your unit will largely depend on the size of your house and windows. The cooling load required for your building must be considered. A large unit doesn’t translate to efficiency. You need the input of your engineer in determining the size of the unit in relation to your cooling load needs for the building.

These tips will assist you in choosing the perfect HVAC system for your home or commercial building. Rely on the input of your engineer, architect and contractor in determining the best air conditioning unit for your building.
