How to Choose an Energy-Efficient Air Conditioner

There is possibly no modern invention more essential to comfortable living than air-conditioning. Air conditioners today—from window units to central systems—are more energy efficient and cost effective than ever before, so your energy bill doesn’t have to go up while you cool down.

It’s a wonderful feeling: walking out of the sweltering heat and humidity of an August day into a room that has been cooled to the ideal home temperature. And air-conditioning is still a relatively modern invention!

How to choose an air conditioner size

Properly sizing an air conditioner is important to ensure your home is cooled without using excess energy. Air conditioners work by (1) reducing the humidity and (2) reducing the temperature. A larger A/C will not cool your space faster and better—but it will cool the air faster than it can remove the humidity, so what happens is that the air turns damp and clammy.

It’s easy to choose the right size, however, because useful websites like ENERGY STAR® provide an air conditioner BTU chart that tells you what size model you need for your size space. Simply measure your space to figure out the square feet you’re trying to cool, and then consult an air conditioner BTU chart (like this ENERGY STAR® chart) to figure out how many BTUs you need for that size of space.

When selecting the size of a central air conditioner for your home it is important to check the “tonnage” for each model. According to Energy.gov, one “ton” is equivalent to 12,000 BTU per hour, and sizes generally range from 1- to 5-ton units. The tonnage required for your A/C may increase depending upon factors such as your local climate and the square footage of your home.

If you are looking to purchase a new central air conditioner, ENERGY STAR® offers equipment sizing guidelines to help you select the correct size for your home.

Choosing Between Different Types of Air Conditioners

Different types of air conditioners are better suited for different living spaces. For instance, if you live in an area that experiences intense heat for a majority of the year then you’ll probably want a split or packaged air conditioner. But if you’re unable to install central air in your home for whatever reason, you may have to look at a window unit or a portable air conditioner.

You’ll also need to keep in mind the air conditioner sizing before deciding what unit to buy - having the wrong sized A/C unit for your room could increase your energy bill. To help you make a more strategic decision here are some of your options:

What is an evaporative cooler?

If you live in the Western United States you may be familiar with the evaporative “swamp” cooler. The evaporative cooler is an alternative to standard air conditioners that draws hot, dry air through damp pads, adding moisture to the air. Usually, evaporative coolers are less costly to build and install since they’re basically a powerful fan with a pad that collects and redistributes cool, damp air back into your home. They are also less costly to run, using as little as a quarter of the electricity used by an air conditioner. Evaporative coolers also don’t use any environmentally unfriendly chemicals such as those found in older A/C units.

Evaporative coolers aren’t recommended if you live in the Eastern United States--just regions like Nevada or New Mexico that have a hot, dry climate. If you live anywhere with high humidity, evaporative coolers could fill your rooms with hotter, more humid air, so while the cost and potential energy savings may sound enticing, it’s strongly advised that this device is only used in appropriate regions and you will be far better off using a regular energy-efficient air conditioner.

When building a new home, there are many things to consider. Among the most important is the type of air conditioning (AC) system you will use. Whether you opt for a ductless mini split AC system, window air conditioners, floor-mounted AC units, central AC, hybrid/dual fuel AC, or a smart AC system, there are certain features that you should look for to ensure your comfort.

Here are seven must-have modern AC features for new homes:

1. A High SEER Rating

The Seasonal Energy Efficiency Ratio (SEER) is a measure of an AC unit’s efficiency. The higher the SEER rating, the more energy-efficient the unit. To qualify for ENERGY STAR certification, an AC unit must have a SEER rating of 14 or higher. However, newer units can have SEER ratings as high as 26. These units save money on your energy bills and help to reduce your carbon footprint.

Experts offering AC replacement services recommend opting for a unit with a high SEER rating, especially if you live in an area with hot summers. Look for an ENERGY STAR label when shopping for a new AC unit or consult a professional to find the most energy-efficient model.

2. Variable Speed Operation

Most AC units operate at a single speed, running full blast until the desired temperature is reached and then cycling off until the temperature starts rising again. However, newer units feature variable speed operation, allowing them to run at lower speeds for longer periods. This not only saves energy but also helps to reduce wear and tear on the unit, extending its lifespan. If you’re considering an upgrade or need maintenance, scheduling AC service in Houston can help ensure your system is optimized for performance and efficiency.

3. A Smart Programmable Thermostat

A smart programmable thermostat with Wi-Fi connectivity gives you complete control over your AC unit from anywhere in the world. Using your smartphone, tablet, or computer, you can access your thermostat remotely and make adjustments as needed. Some wireless thermostats even allow you to schedule regular temperature changes based on your daily schedule or when you are away from home for extended periods.

4. Zoning Capabilities

Zoning capabilities allow you to divide your home into separate “zones” and customize the temperature in each one independently. This is especially helpful if you have rooms used less frequently or located on different floors of your home. Only cooling the rooms that you are using can save money on your energy bills without sacrificing comfort.

5. Air Filtration and Purification Systems

The latest AC units now come with built-in air filtration and purification systems. Featuring HEPA filters, activated carbon filters, and ultraviolet germicidal irradiation (UVGI) technology, these systems help to remove pollen, dust, mold spores, bacteria, and viruses from the air. This can be especially helpful for people with allergies or respiratory conditions like asthma. These features provide an extra layer of protection for you and your family.

All Filters offers a comprehensive selection of various filters, including AC, ensuring optimal performance and air quality in your AC unit.

6. Quiet Operation

Many newer AC units feature technology that significantly reduces noise during operation. If you want an AC unit that won’t disturb your peace and quiet, look for one with a decibel rating of 50 or less. You may even want to consider investing in a soundproofed enclosure for outdoor units to reduce noise levels further.

7. Connectivity to Smart Home Systems

Integration with smart home systems is another key feature to consider. This allows you to control your AC unit using voice commands, mobile apps, and even smart home devices such as Amazon Echo and Google Home. In addition to enjoying the convenience of hands-free operation, you can also take advantage of features such as energy reporting and remote access across integrated devices. This is a must-have feature for smart homes of the future.

Know What You Need and Consult HVAC Experts

No matter what features you are looking for in an AC unit, be sure to keep these seven must-haves in mind. With so many options on the market, it can be easy to get overwhelmed. However, if you know what you need, you can narrow down your choices and find the perfect unit for your new home. Consult with a professional HVAC contractor to help you make an informed decision.
