Living in an air conditioned space can be a game-changer, especially during hot summer months. The benefits are numerous and can have a significant impact on your overall well-being.
Air conditioned spaces can help reduce the risk of heat-related illnesses, such as heatstroke and dehydration. This is particularly important for vulnerable populations like the elderly and young children.
Proper air circulation and temperature control can also improve sleep quality, leading to better rest and increased energy levels. I've noticed this firsthand, as I've slept more soundly in air conditioned spaces myself.
By maintaining a consistent temperature, air conditioning can also help alleviate allergy symptoms and respiratory issues. This is because it reduces the presence of dust mites, mold, and other allergens that thrive in warm environments.
Choosing the Right AC
Choosing the right air conditioner size is crucial to minimize your electricity bill. A small air conditioner will struggle to cool a large room, while a huge one might cool it quickly but leave it clammy.

To determine the right size, you need to consider the room's area, the number of people regularly in the room, and its exposure to the sun. You can use an air conditioner room size calculator to get the recommended output power. If you don't know your room's area, you can measure it using a measuring tool and input the values into the calculator.
Here's a chart to help you find the recommended base air conditioner capacity based on your room's area:
You should also consider the ceiling height and the number of people regularly in the room. For every foot above 8 feet, you need to add 1000 BTU/hr to the recommended capacity, and for each additional person, you need to add about 600 BTU/hr.

If you don't know your room's size, you can use a measuring tape to find it. Once you have the size, you can use an air conditioner room size calculator to determine the recommended output power your air conditioning unit needs.
The recommended base air conditioner capacity depends on the room's area. According to the chart, for a room area of 100-150 square feet, the recommended capacity is 5,000 BTU/hr. For a room area of 150-250 square feet, the recommended capacity is 6,000 BTU/hr, and so on.
Here's a chart to help you determine the recommended air conditioner capacity based on room size:
You also need to consider the number of people regularly in the room. For every additional person, you need to add about 600 BTU/hr to the recommended capacity.
Types of
There are several types of air conditioners to choose from, each with its own unique features and benefits.
Split wall-mounted ACs are a popular choice, consisting of an indoor and outdoor unit connected by plumbing that's fed through the wall.
Ductless air conditioners, also known as mini-splits, are perfect for heating and cooling individual rooms without the need for ductwork.
Portable air conditioners are lightweight and self-contained, making them ideal for small spaces and easy to set up on the floor.
Window air conditioners are small and can be installed in a window frame, operating by forcing cold air into the space while sucking hot air out.
Here are some of the main types of air conditioners to consider:
- Split wall-mounted AC
- Ductless air conditioner (mini-split)
- Portable air conditioner (PAC)
- Window air conditioner
Understanding AC Basics
Central air is a type of air conditioning system that cools the entire house. It's typically more efficient than window units because it can control humidity, air quality, and airflow within your home.
A central air conditioning system usually consists of two main parts: an outdoor unit and an indoor unit.
The outdoor unit houses a fan, condenser coil, and compressor.
The indoor unit typically houses the evaporator coil and fan to circulate the cooled air.

The AC Process
The AC process is pretty straightforward. Air conditioners use refrigerant to remove heat from your home or office, and then move that cold air into your building through ducts.
Warm indoor air is cooled as it passes through a refrigerant-filled, cold cooling coil. The refrigerant absorbs heat from the indoor air as it transforms from liquid to gas.
The cooled air is returned to the house, making your space feel cooler and more comfortable. This process is repeated over and over again until everything inside gets cooled down as much as possible.
The refrigerant gas is compressed before entering the outside unit's big coil. A big fan pulls outside air through the exterior coil, rejecting the heat that was absorbed from the house.

AC Efficiency and Cost
Choosing the right air conditioner can be a bit overwhelming, but let's break it down. To ensure your new air conditioner performs at its rated efficiency, you should replace your heating system at the same time. This is especially true if your furnace is over 15 years old.
ENERGY STAR certified air conditioners have higher seasonal energy efficiency ratio (SEER) and energy efficiency ratio (EER) ratings, making them a more energy-efficient choice. They can also help you save money on utility bills by reducing energy consumption.

Billions a Year in A.C.?
According to the U.S. Energy Information Administration, air conditioning uses about 6% of the country's electricity.
In the summer, it's not uncommon for households to see their energy bills skyrocket.
The average American household spends around $1,300 on air conditioning each year.
A well-maintained air conditioner can pay for itself in energy savings.
Older AC units are often less efficient and can end up costing more in the long run.
In fact, replacing a 10-year-old AC unit with a new one can save up to $1,000 per year on energy costs.
Regular maintenance is key to keeping your AC running smoothly and efficiently.
By investing in a programmable thermostat, you can save up to $150 per year on your energy bills.
It's a small investment that can pay big dividends in the long run.

Energy Star Home Upgrade
Upgrading to an ENERGY STAR certified heating and cooling system can save you money on utility bills and help protect the environment.
ENERGY STAR certified air conditioners have higher SEER and EER ratings, making them more energy-efficient.
Replacing your heating system at the same time as your air conditioner is recommended, especially if your furnace is over 15 years old.
This ensures that your new air conditioner performs at its rated efficiency.
Central air conditioners were originally qualified for the ENERGY STAR label in April, 1995, marking a significant milestone in energy-efficient technology.
By choosing an ENERGY STAR certified system, you can enjoy a more comfortable home while reducing your energy consumption.

Central air conditioners originally qualified for the ENERGY STAR label in April, 1995, and it's a good thing they did, because it's helped people save energy and money on utility bills.
The only way to ensure that your new air conditioner performs at its rated efficiency is to replace your heating system at the same time, especially if your furnace is over 15 years old.
If you purchase a new energy-efficient air conditioner but connect it to an older furnace and blower motor, your system will not perform to its rated efficiency.
