How Air Conditioning Affects Climate Change and Vice Versa

Air conditioning is a double-edged sword when it comes to climate change. On one hand, it helps us cope with the rising temperatures and extreme heat waves that are becoming more frequent and severe due to global warming. According to the World Health Organization (WHO), heat stress is responsible for more than 160,000 deaths per year worldwide¹. Air conditioning can prevent heat-related illnesses and deaths, as well as improve productivity, comfort, and quality of life.

On the other hand, air conditioning also contributes to climate change by increasing the demand for electricity, which is often generated from fossil fuels that emit greenhouse gases. According to the International Energy Agency (IEA), air conditioners account for about 10% of global electricity consumption². Moreover, some air conditioners use refrigerants that are potent greenhouse gases themselves, such as hydrofluorocarbons (HFCs). If left unchecked, the growing use of air conditioning could offset the efforts to reduce greenhouse gas emissions and mitigate climate change.

Therefore, it is important to find ways to reduce the environmental impact of air conditioning while still enjoying its benefits. Some of the solutions include:

• Improving the energy efficiency of air conditioners by using better technology and design
• Replacing or phasing out HFCs with alternative refrigerants that have lower global warming potential
• Adopting passive cooling strategies such as shading, insulation, ventilation, and natural materials
• Using renewable energy sources such as solar or wind power to run air conditioners
• Raising awareness and changing behavior to optimize the use of air conditioners

The Different Types of Home Air Conditioners and Their Pros and Cons

There are various types of home air conditioners, each with its own advantages and disadvantages. Here are some of the most common ones:

• Central air conditioners: These are systems that cool the entire home by distributing cold air through ducts and vents. They are usually controlled by a thermostat and can be integrated with smart home devices. They are ideal for large spaces that need uniform cooling. However, they are also expensive to buy and install, require regular maintenance, and may lose some energy through duct leaks.
• Window air conditioners: These are units that fit in a window opening and cool a single room or area. They are easy to install and remove, relatively affordable, and efficient for small spaces. However, they are also noisy, block natural light and views, reduce security, and may not fit in some windows.
• Portable air conditioners: These are units that can be moved from room to room on wheels. They have a hose that vents hot air outside through a window or a wall. They are convenient, flexible, and suitable for spaces where window or wall units are not allowed or feasible. However, they are also bulky, heavy, noisy, less efficient than window units, and require manual draining of condensate water.
• Ductless mini-split air conditioners: These are systems that consist of an outdoor compressor unit and one or more indoor evaporator units that are connected by pipes. They can cool different zones independently without using ducts. They are quiet, efficient, and customizable. However, they are also costly to buy and install, require professional installation, and may affect the aesthetics of your home.

The Tax Incentives Available for Buying and Installing Energy-Efficient Air Conditioners

If you are planning to buy and install an energy-efficient air conditioner for your home, you may be eligible for some tax incentives that can help you reduce your costs. The federal Inflation Reduction Act, passed in 2022, expanded and extended the tax credits available for energy-efficient home improvements, including HVAC system components⁶. An array of ENERGY STAR certified equipment is eligible for the tax credits, including:

• Air-source heat pumps
• Biomass fuel stoves
• Boilers
• Central air conditioners

The tax credit is effective for products purchased and installed between January 1, 2023, and December 31, 2032. You can claim:

• 30% of project cost
• $600 maximum amount credited for central air conditioners

There are also annual limits on the total amount of credit you can claim for any combination of eligible products, as well as specific limits for certain types of products. The overall total limit for an efficiency tax credit is $5,000 per taxpayer. The specific limits for certain types of products are:

• $300 for air-source heat pumps
• $300 for biomass fuel stoves
• $150 for boilers
• $50 for advanced main air circulating fans

To claim the tax credit, you will need to file Form 5695 with your federal income tax return. You will also need to keep a copy of the manufacturer’s certification statement and your receipt or invoice as proof of purchase and installation. irs.gov.

The tax credit is nonrefundable, which means it can only reduce your tax liability to zero. If your credit amount exceeds your tax liability, you cannot carry over the excess to future years. However, you can claim the credit in the same year as other tax credits, such as the residential renewable energy tax credit or the electric vehicle tax credit.

The tax credit is not available for rental properties or second homes. It is only available for your main home where you live most of the time. The home must be located in the United States and be an existing home, not a new construction.

For more information on the tax credits for energy-efficient home improvements, visit the IRS website or consult a tax professional.

By taking advantage of the tax incentives available for buying and installing energy-efficient air conditioners, you can not only save money on your cooling bills, but also reduce your carbon footprint and help fight climate change. It’s a win-win situation for you and the planet!
