How an HVAC Economizer Can Cut Down Your Energy Bill?
Updated: Jul 13
Mention the word economizer to most people and you will get blank stares, that is until you mention how much energy and money savings you will get with an HVAC economizer at that point, everyone wants to know more.
Air conditioning units consume copious amounts of energy which can add up to high energy bills and a negative environmental impact.
We all look for ways to save on our energy bills, which can hit especially hard when the temperatures reach extreme highs and extreme lows.
You can regain control of your utility bill by installing an air-side economizer and take advantage of ‘free cooling’.
Check out our explanation of exactly what an economizer is and how ‘free cooling’ can benefit you.
What is an HVAC Economizer?
An economizer for HVAC is a device created to minimize the consumption of energy via an air conditioning system.
Usually, an economizer is roof-mounted on a commercial building.
An economizer is a device made up of sensors, dampers, actuators, and controls that, when all put together, carry outside air into a building to replace mechanical cooling in an air conditioning system.
With the use of sensors, the economizer is able to determine whether the outside air is appropriate at the time to cool the indoors.
The economizer switches to minimal ventilation when outside air temperatures are unfavorable for cooling the inside.
Simply put: if a building is too hot, an economizer reduces your air conditioning costs by using outside air for free cooling, meaning your compressor can run less.
Take Advantage of Free Cooling
Free cooling is any method used to decrease the runtime of a cooling system or the amount of energy consumption a cooling system requires to cool a building.
Free cooling is typically used in mild climates like Kansas City and is achieved when the outside air is filtered and brought inside.
Normally, free cooling is a result of the application of economizers installed by an HVAC technician which function to use cool air from cooler outdoor temperatures to cool the indoors for free.
Free cooling is more economical because it uses “free” air to assist in chilling the water that is required to filter through an air conditioning system.
By using free cooling, both industrial air conditioners will require less energy to function and can save your business a lot of money.
Invest in an HVAC Economizer
The installation of an HVAC economizer will not only save you money, but it is also good for the environment. Here are some of the main reasons why you should consider installing an economizer for your industrial HVAC system:
It reduces the runtime of your air conditioning unit, prolonging the life of the system: Not only does a reduction in your air conditioners runtime save you money, but it also lessens the wear and tear on your air conditioning system which in turn equals reduced maintenance costs, fewer breakdowns, less downtime and a longer lifespan for your system.
It improves ventilation and air quality: Unless a building has been recently retrofitted, a lot of systems will have inadequate ventilation systems. An economizer can enhance indoor air quality (IAQ) and ventilation control by removing old air that contains volatile organic compounds (VOCs) and introducing fresh air indoors- your employees and customers will thank you!
It lowers your energy expenditure to lower your bills: Rather than always relying on the use of your AC system to keep your property cool, it “outsources” this work and makes the outside air cool it instead. More time using the economizer means less A/C time and less money going out the window.
When you see the benefits of installing an economizer, it is easy to see how, for a small investment in the economizer, you will improve the air quality of your building and save money in the long run. It’s a win-win!
How Installing an Economizer With Dillon’s Heating and Cooling Can Help You Save Money
Integrating an HVAC Economizer
While some HVAC systems are already equipped with an economizer, older systems may not be.
If your building’s HVAC system does not have an economizer, contact a professional HVAC contractor like Dillon’s Heating and Cooling to retrofit your equipment so that you can take advantage of the free cooling and save some money.
Concerned about downtime? The addition of an economizer is not a major mechanical undertaking and fits well with most HVAC equipment.
Is Your Building Suitable for an Economizer?
If you have been convinced that you need an economizer so that you can take advantage of free cooling, you may be wondering if your building could house one.
Economizers are best suited for a moderate to cool environment without a lot of humidity, and our climate in the Kansas City area is perfect.
Nonetheless, in hot climates where the air cools considerably at night, an economizer can make for a successful energy saver.
In fact, economizers are so great for efficiency that some states are changing commercial building codes to include economizers as a compulsory addition to HVAC systems due to energy conservation purposes.
Integrating an HVAC Economizer
The great news is that economizers are suited to buildings of all sizes. This is especially true of buildings with high-needs for cooling, like data centers.
Since economizers offer such excellent benefits as improved indoor air quality and energy savings, they should be part of almost every new commercial HVAC installation.
How Do I Know if I Have an Economizer?
As a property manager or building owner with many things to take care of on your plate, it can be hard to know if your building has an economizer.
And, if your building does, is it working exactly as it should? Without an economizer, you could be paying more than you need to keep your property and its occupants comfortable.
Give the experts at Dillon’s Heating and Cooling a call to discover more about how an economizer can extend your HVAC unit’s longevity, help save you money and improve your indoor air quality.
The use of outside air to cool the inside of buildings via an economizer means that air conditioning units (that typically expends large amounts of energy) are able to remain idle.
You will not have repairs as frequently, which will save you money in repair costs.
