What is your carbon footprint?

At Critical HVAC Systems, we value decreasing energy consumption and energy costs for our clients. These values may not always be on the top of the to do list, but the impact of a couple of minor changes to your business is worth sharing knowledge about.

We offer a wide range of sustainable services to aid businesses in lowering energy costs and preventative maintenance programs designed to reduce outages and lower cost of ownership.

We are all working as a team here to better the world around us. We would love to help your business by reducing energy consumption and operating costs, and contribute towards a cleaner environment.


How Can I Reduce My Energy Costs?

In commercial facilities, lighting and HVAC commonly are the two largest consumers of energy. However, there are multiple factors that that must be considered when evaluating options for energy savings.  There are several steps that can be taken to reduce energy costs:

  • Regular filter replacements – consistently replacing filters is the best way for consumers to reduce energy costs and improve Indoor Air Quality (IAQ).
  • Preventative maintenance program – A proper preventative maintenance program can reduce operating expenses by up to 40%.  It is also crucial to ensure that your system is running at optimal levels.  Improper airflow is the most common result of a neglected system.  This causes your unit to work harder, consume more energy, and results in a higher level of mechanical failures than a properly maintained system.  Our Preventative Maintenance program is based on Manufacturer guidelines and industry best practices, customized to the needs of your facility.
  • Reduce Heat load – Advances in technology have made Green Energy solutions practical where they may not have been in the past.  Depending on your environment and occupant habits there are multiple options for Building Owners and Facilities managers to reduce energy consumption.  Installing Occupancy sensors, LED Lighting, Window treatments, Insulation, Cool Roof Coating (CRC) and other options can significantly reduce heat load in a building, directly reducing energy costs.
  • Building Automation Systems (BAS) –  Leverage Building Automation Systems to ensure optimal performance of your system.  However, it is not enough to have a system in place.  Building owners and facilities managers must also be diligent in monitoring system performance to ensure Occupant behavior does not contribute to excessive energy consumption.  It is not uncommon for set points or schedules to be adjusted or overridden based on user preference, often without the knowledge of the Facilities manager.
  • Upgrade to a high-efficiency system – In most cases, it is not cost effective to upgrade to a high efficiency system if existing equipment is well maintained and free of major mechanical problems.  However, in extreme cases, it can be cost effective to replace the entire system.  By combining our expertise and industry best practices, we can provide business case data to help building owners and facilities managers make the best decision for their business.

Even if your facility has these solutions in place, it is critical to evaluate as your facility ages.  As an example, window film degradation of UV protection begins around the 5-year mark and thermal loss around 15.  Our expertise allows us to identify practical, cost effective solutions that make sense for your business.

How can Critical HVAC Systems help manage my energy consumption?

Our goal is to function as a strategic partner for our customers.  We are and will continue to be HVAC experts, but there are multiple factors that drive HVAC usage.  Our value lies in our ability to develop practical, real-world solutions with two primary objectives:

  • Proactively address the entire building envelope and heat load vs. strictly focusing on the HVAC system
  • Retrofit existing HVAC systems with more energy efficient components without having to upgrade the entire HVAC system.

This allows us to address sources of heat and humidity that impact the overall performance of your system.  By doing so, we can provide our customers with a sustainable solution that will significantly reduce energy consumption and overall cost of ownership.

Energy Audits & Benchmarking

“If you’re not matching your business performance to a higher standard, your business can stagnate and never reach its full potential.”

The City of Atlanta’s Commercial Buildings Energy Efficiency Ordinance requires owners of commercial buildings over 25,000 sq. ft. to benchmark energy and water consumption on an annual basis through ENERGY STAR Portfolio Manager, as well as have an ASHRAE Level 2 Energy Audit performed every 10 years.

Critical HVAC Systems wants to help your business with establishing or maintaining benchmark data for your facility. We can provide the following services.

  • Input and manage sites through EPA Portfolio Manager
  • ASHRAE audits. 


As see to the right, almost half of commercial building energy use is consumed by lighting. “Smart Lighting” is the #1 energy solution of today. A simple lighting exchange and occupant sensors can lead to huge savings for your business!

We provide the following services:

  • Retrofits & replacements
  • Occupancy sensors

Building Envelope Services

In addition to lighting consumption, businesses’ power bills are skyrocketing due to improper installations of buildings. Improper installation leads to wasted energy. Whether it be cooling or heating season, maintaining proper building envelope separation between your business and the outdoors can help bring down those power bills and keep employees confortable!

Critical HVAC Systems can provide the following building envelope services:

  • Windows
    • Heat/UV & Security Film
  • Roofing
    • Cool Roof Coating (CRC)
  • Sealing & Hardening
