Earth Day is a time to think about our air conditioner’s impact on the planet, and on our wallets. Regardless of your personal views on climate or environmental policy, one thing we can all agree on is the benefit of using less energy, spending less money, and getting more comfort in return.
At Kingdom Air, we believe these changes in your home’s HVAC system can make a big difference. Here’s how to reduce waste, increase efficiency, and save money, all while doing your part this Earth Day.
1. Keep Debris Out and Filters Clean
Let’s start with the basics. A dirty HVAC system doesn’t just work harder—it works less efficiently, costing you more and wearing out faster.
What can you do?
-
Make sure your outdoor unit is free of leaves, grass, pet hair, and other debris.
-
Change your indoor air filters regularly—every 1 to 3 months, depending on your system and lifestyle.
What can we do?
Kingdom Air offers a comprehensive preventative maintenance service for just $89. We’ll clean your system inside and out, check refrigerant levels, test electrical components, and ensure your system is running smoothly and efficiently.
2. Install a Smart Thermostat
A programmable or Wi-Fi-enabled thermostat can have a huge impact on your energy consumption—without sacrificing comfort.
Set your system to run less when:
-
You’re at work
-
You’re sleeping
-
You’re on vacation
Even bumping your temperature up a few degrees in the summer while you’re away can lead to noticeable savings. Many smart thermostats can be adjusted right from your phone, so you’re always in control, no matter where you are.
Kingdom Air installs a wide range of smart thermostats and can help you choose one that fits your system and lifestyle.
3. Add or Improve Attic Insulation
Proper insulation is one of the most overlooked yet effective ways to improve HVAC efficiency. Something as simple as checking the level of blown-in insulation in your attic can make a world of difference.
Adding insulation is often a one-time upgrade that pays off for years to come—especially if you plan to stay in your home long term. Less heat gets in during the summer, and less warmth escapes during the winter, meaning your system doesn’t have to work as hard.
4. Keep Windows (and Curtains) Closed During the Heat of the Day
We all enjoy natural light—but during hot months, that sunlight turns into unwanted heat.
Here’s what you can do:
-
Close your windows during the heat of the day
-
If you have storm windows or a second pane, make sure those are closed too
-
Keep curtains or blinds drawn in rooms that get direct sunlight
The double window effect acts as an insulator, keeping cooled air in and hot air out. Combined with drawn curtains, this simple step eases the load on your AC and reduces your energy bill.
5. Replace Systems Using Obsolete Refrigerants
If your air conditioner runs on R22, you probably already know it’s banned and hard to find. But did you know 410A is no longer being produced as of January 1, 2025?
That’s right—the government has phased out production of older refrigerants in favor of safer, more environmentally-friendly alternatives. If your system uses either of these refrigerants, replacement parts, refrigerant, and repairs will only get more expensive as time goes on.
If your unit is:
-
Over 10 years old
-
Out of warranty
-
Showing signs of wear
…it might be time to upgrade. Replacing your unit before refrigerant shortages and part prices surge can save you money—and future headaches.
Looking for the Elite in Energy Efficiency?
If you want to take your commitment to the next level, consider upgrading to one of the most efficient systems available:
-
A geothermal HVAC system
-
A state-of-the-art heat pump system
These systems represent the gold standard in energy efficiency, offering unmatched performance, lower operating costs, and a smaller environmental footprint.
Whether your goal is to reduce your utility bill, make an environmentally responsible choice, or enjoy the ultimate in comfort—Kingdom Air is here to help.
