Air Conditioners

Summertime is a time for family, recreation, vacations, and air conditioning. When the heat and humidity start to take their toll, air conditioners are an essential part of an enjoyable summer. To make sure that you are never without air conditioning on a hot and humid summer day, we offer the following information. How does air conditioning work? What are the essential ingredients for cooling? What kind of AC unit is right for your home? And, how can you reduce the cost of cooling your home throughout the summer months?

Cost Calculator for Air Conditioners

When you purchase an air conditioner you will pay for the equipment and the installation. And, you will pay to run your AC to keep your home comfortable. There will be maintenance costs and you will need to pay for repairs when required. Take a look at our cost calculator before considering any quotes from dealers or AC technicians. One of the first things to consider is what kind of system you need and what capacity it has to have. If you only need an air conditioner, that is one thing but if you need to heat your home as well, you need to consider a furnace or perhaps a heat pump that can do both jobs. Energy efficiency is important as are ease of operation and a quiet-running unit.

When Was Air Conditioning Invented?

Although refrigeration was first invented in 1851, it was not until the dawn of the 20th century that Willis Haviland Carrier invented a machine that cooled indoor spaces. The term air conditioner was patented around this time. However, home air conditioning units were not available until 1929 and it took until 1947 for affordable home air conditioners to appear on the market.

How Does Air Conditioning Work?

The majority of air conditioning units use a refrigeration cycle to cool the air in your home. But, some use evaporation to achieve the same goal.

of Your Air Conditioner

Air conditioning systems have five major components.

Thermostat: This is the device that monitors temperature and turns the AC unit on and off in order to maintain your home temperature within the desired range.
Evaporator: This is the core or coil full of refrigerant that absorbs heat and creates the cold used to cool your home. It is where liquid refrigerant turns to gas.
Condenser: This is the unit outside of your home where the refrigerant loses the heat it picked up in the evaporator.
Expansion valve: The expansion valve is where warm, liquid refrigerant turns to cool liquid refrigerant on its way to the evaporator.
Compressor: This is the part of the system that increased the pressure and temperature of the refrigerant before it gets back to the evaporator.

Air Conditioner Types

There are different kinds of air conditioners and they are useful in different situations.

Split AC Systems
A split AC system has two distinct parts, one inside the house and the other outside of the house. The cold expansion value and evaporator coil part are inside your home. The system is placed in your furnace or other air-handling system. The air-handling system blows air over the coil and through the ducts throughout your home. The hot part is the condenser unit which sits on a cement slab outside of your home where it releases heat.

Ductless AC Units
A ductless AC system is a split system as well. But, the cooling unit that takes heat out of your home is mounted on an inside wall. It contains the evaporator and a small fan that blows cool air directly into the room where the unit is mounted. The outside part is the condenser and, like with the other split system it is placed outside of your home. If you want to cool more than one room with this kind of system you typically need wall-mounted cooling units in more than one room.

Packaged AC Units
These are inside units that contain all of the parts of the system in one box. The heat is generated using natural gas or a heat lamp run by electricity.
A packaged terminal AC system is also known as a wall-split AC system. They are usually installed in the wall of a building with the cooling parts on the inside and the condenser parts of exhausting heat on the outside.

Buying Your New Air Conditioner

New AC units are expensive so give some serious thought to the process before you go shopping. When you know what to consider, you will know why some units are more expensive than others and why. Then you get to make an informed decision about which you need for your home.

Choosing an HVAC Contractor

Your HVAC contractor will be your most important source of information about your air conditioning system and you may, in fact, purchase your unit from them. As such, choosing the right HVAC contractor is important.

Check the SEER Rating

SEER stands for seasonal energy efficiency ratio. It is a way to make sure that your new AC system will be energy-efficient and not each a hole in your pocketbook. It specifically has to do with how many BTUs of heat are removed per hour divided by the number of watts of electricity needed to do the job.

Type of Compressor

Here you have two choices. There are single stage and two-stage compressors. The single stage compressor has one speed only. Compared to the two-stage compressor it turns on and off more frequently and uses more energy.

Condenser Fan Motor

This motor is responsible for keeping the compressor from overheating and for cooling the super-hot refrigerant coming out of the condensing coils on the outside part of the unit. Through routine maintenance, this fan motor will last longer. Nevertheless, they can breakdown.

Types of condense fan motors

Like with the compressor, you can get a single-stage fan motor that only has one speed or a variable speed motor that helps you save energy. A variable speed motor saves you money, is not constantly turning on and off, and can take forty percent off of the energy usage you are paying for.


“I am so thankful to have found this company. Gave them a call after reading reviews and they exceeded my expectations!! They came out at approximately 7PM and we’re wrapped up at about an hour later. They even took the time to show me how to work my thermostat and give an in-depth explanation of how the unit works! Will most definitely use again, Mr Alan and his team get an A+ in my book!”

Great service! Very friendly! Josh and Alan were great! Quick response! I’m very pleased with their service and glad they were recommended to me.
