What Is an HVAC System?

An HVAC system is composed of equipment that is designed to heat, cool, ventilate, and distribute air.  Cooling equipment includes chillers, cooling towers, heat pumps, and direct expansion systems. Heating equipment includes boilers, furnaces, heat pumps, and direct-fired electric and gas air heaters.


But for most building operations professionals running older HVAC equipment, it’s not the ‘what” that’s a mystery, but the “how.” That is, how to keep equipment in good operational condition, rein in high costs, meet energy and emissions mandates, and keep occupants happy, all with limited maintenance funding.


That’s where ESG comes in. Whether your equipment is outdated, out of balance, or just worn out, we can co-design solutions with you that will impact every aspect of your operations.

Do More Than You Thought Possible

Maximize energy efficiency, improve indoor air quality, and enhance occupant comfort, all while lowering your energy bills.


So why not take the pressure off? We’ll help you build a solid financial case with energy-efficient solutions that help pay for themselves.

Get out of the hot seat.

As units age, they operate less efficiently, consume more energy, and are prone to more failures and increasingly costly repairs. You know what that means: more pressure on your budget and your resources.

Boost Your Operational Advantages

More than just conditioned air, an energy-efficient HVAC system can deliver big benefits to your stakeholders and your bottom line.


Improve Indoor Air Quality

Reduce or eliminate the growth and distribution of airborne contaminants for a healthier indoor environment.


Lessen Your Environmental Impact

Meet your environmental goals and shrink your carbon footprint with equipment that complies with current environmental and energy standards.


Reduce Immediate and Long-Term Expenses

Slash your utility bills and pare down your long-term repair and maintenance expenses with state-of-the-art systems.


Increase Thermal Comfort

Ensure reliable temperatures and consistent humidity to elevate occupant satisfaction.

Our entire process is dedicated to designing practical HVAC energy efficiency solutions with you that will work for you.

When you team up with ESG, you’ll get more than just an HVAC installation.

Because we don’t manufacture or profit from selling equipment, our energy engineers are free to recommend the best, most cost-effective solutions for you. Don’t have the time or capacity to operate or maintain your equipment? We’ve got it. We can even explore opportunities to bundle other energy conservation measures with your project to amplify your energy savings.


We’re in it for the long haul, supporting your mission every step of the way.
