Air Conditioning Installation

Once we arrive, we’ll do a complete diagnostic of your system to find out what’s wrong and what’s about to go wrong. We’ll show you the options to perfectly repair and even improve your air conditioner. You choose what’s best for you and pay the price quoted you upfront. No surprises, only satisfaction, or we’ll make it right—guaranteed.

Any recommendations we make are covered by our Green Horizon One Hour Whole House Promise to make your air conditioning more efficient, or you get your money back. The only thing better? Discounts Top Gun Club members receive.

When the time comes for Air Conditioning Replacement, trust Green Horizon One Hour Heating & Air Conditioning. We spend a lot of time listening to what you want before we ever recommend a new air conditioner for your home. Then we present options and recommendations based on what you’ve told us. We’ll help you hit your budget and improve your home’s efficiency. Otherwise, we’ll replace it or give you your money back within one year.

We also specialize in geothermal system installation. It’s quite a bit more expensive than a traditional air conditioner, but the reduction in energy bills can offset the higher cost in the first few years and then put money in your pocket every year after that. Not to mention, it’s the most painless form of cooling and heating for our environment, which is really cool.

Air Conditioning Maintenance

Our air conditioner optimizer mega tune-up is the best way to prevent breakdowns and save money every month. That’s because dirt and dust are the #1 killer of air conditioners. The cleaner they are, the smoother and easier they run. That means less energy use and more money staying in your bank account. You’ll save way more than the service cost in lower utility bills and extended system life.

Top Gun Club

Our Top Gun Club receives an air conditioning and heating optimizer every year plus discounts on repair, installation, upgrades and priority service when everyone else has to wait. The amount you save is always more than you pay to join the family.

FREE benefits for active and retired military

You’ve put yourself in the line of fire for us. The least we can do is maintain your air conditioner for you for FREE. We’ll visit your home once every year to make sure everything’s running in tip-top shape. You also get the same discounts we provide for our Top Gun Club members. We know what it means to be willing to give the ultimate sacrifice for your country. Let this be our way to say thank you.

Mini Split Air Conditioners

We install Mini Split Air Conditioners when you need low-cost heating and air conditioning and don’t have ductwork. They can be placed anywhere and controlled by a simple remote which gives you absolute control over the room where they live. They’re also a great environmental option because they’re highly efficient.

Smart Thermostats

Whether you are looking to increase efficiency and save money on your energy bill, or you just like to stay up-to-date on the latest technologies, smart thermostats are the answer. We can help you install and program a smart thermostat in your home when you are ready to take the leap into the future of home heating and cooling. Installation is simple and integrates easily into your home’s existing system. See some of the benefits of a Nest Thermostat below.


Unlike many smart home devices, the Nest thermostats offer the latest in thermostat technology without the high price tag. In fact, these thermostats often save homeowners enough on their heating and cooling bills to pay for itself in less than two years. Even if you don’t plan on staying in your home for that long, this simple and affordable upgrade in technology can turn into a huge selling point for many potential buyers.


With innovative features such as learning capabilities, Eco Mode, and Home/Away assist, homeowners are saving money on heating and cooling now more than ever. During the first week of use, the Nest Learning Thermostat will record your daily adjustments and create a custom schedule that fits your lifestyle. Instead of blasting the air conditioning or heating when you get home, the Nest will slowly adjust the temperature before you get home, saving your systems hours of work to reach the optimal temperature.

With Home/Away Assist, the Nest will automatically switch to Eco temperatures when you leave and switch back to normal when you return. This feature uses your phone’s location or sensed movement around the Nest device to determine whether or not someone is present in the home. Home/Away can also be manually turned on or off. This way, your systems aren’t continually running when no one is home, but it is still keeping your home at a comfortable temperature for pets and/or plants.

Lastly, Nest Thermostats educate homeowners on energy use to help them choose temperatures that will best save them money. A green leaf appears when a homeowner chooses an energy-saving temperature, which is all based on the homeowner’s previous patterns. It also displays an estimate on the time it will take to reach a desired temperature, this way homeowners can see how long their systems will be running and using energy. Homeowners can also access their history of usage at any time to see how often they were running their systems and what factors influenced the usage, such as weather.


For more precise temperature control, a homeowner can set a schedule up to the hour for temperature adjustments. If you like your home to be cooler at night for sleeping, you can set a low temperature adjustment to kick on an hour or two before bedtime to ensure your environment is ready when you head to bed.

App Access

One of the most exciting features of the Nest Thermostats is that they can be adjusted wirelessly through the Nest App. If you wake up shivering in the middle of the night or forgot to set the temperature before a vacation, you can use the app to remotely adjust the temperature. The app also makes it easier to set a schedule, switch between heating and cooling, and view your energy history.

With smart technologies, saving money on heating and air is easier than ever. Homeowners can also increase the lifespan of their systems by helping them work more efficiently, meaning fewer repairs and replacements in the long run. With our help, you can make the smart switch to smart thermostats today!
