The mechanical system that heats, cools, and ventilates your business is essential to the indoor air quality and comfort of your employees, customers, students, etc. However, it is also one of the most expensive line items building owners face, be it new construction, replacing an old HVAC system, or simply the operating costs for the heating and cooling. An accurately designed HVAC system that is properly balanced will provide healthier indoor air, better energy efficiency with lower utility costs, equipment durability, plus humidity control for maximum comfort. 

We help Chicago business owners tackle the never-ending battle to keep their buildings and/or offices (and more importantly, their customers) comfortable and safe. Is this a battle you may be losing? Do any of the following problems sound familiar?

  • "Is our HVAC system set up to provide the ventilation and filtration our building needs to provide safe indoor air quality?
  • “Every time someone opens the door, my customers feel cold air blowing over them. Is that normal?”

  • “It seems like it’s way too cold or way too warm in my business all the time.”

  • “My heating and cooling bills are higher than ever before.”

  • “Should my windows have so much condensation on them?”

  • “My HVAC contractor says there’s nothing he can do.”

Enhancing Health, Comfort and HVAC Durability in Commercial Spaces

Priority Energy has been at the forefront of designing and testing commercial buildings and mechanical systems for years. We also work with HVAC contractors to properly test and balance mechanical systems. We have been the leader when it comes to forensic analysis of building comfort and durability issues in homes and commercial spaces across the United States. Comfort is something everyone understands, but what do we mean when we say building durability?  Simply put, we mean the structure’s ability to last for generations. Unfortunately, we have seen durability severely impacted by improperly sized mechanical equuipment and unbalanced heating and cooling systems.

What is Air Balancing?

How much air an HVAC system brings indoors versus how much air it expels is known in the industry as Air Balancing. If the heating and air conditioning system expels more air than it takes in, there is a negative air balance. This often happens in older buildings or buildings that have been partially rehabbed. If the system brings in more air than it expels, there can be a positive air balance. Priority Energy will help you maintain a neutral balance, which means the system brings in and expels the same amount of air. 

Priority Energy works with:

  • Restaurants

  • Retail Space

  • Schools/Day Care Facilities

  • Health Clubs and Gyms

  • Cold Storage

  • Office Buildings

  • Warehouse & Trucking Facilities

  • ...And More

We are an industry leader, offering mechanical load sizing services to maximize comfort and indoor air quality.

These services include:

ASHRAE RTS/CLTD & ACCA Manual N Load Sizing

A complete commercial load sizing takes into account

  • The building envelope (walls, doors, windows/glazing, ceilings and orientation)

  • Occupant loads (how many people will be in the space and during what hours)

  • Internal gains (equipment loads, lighting, and any other heat generating items)

  • Ventilation (type of ventilation and total CFMs required)

ASHRAE/ACCA-approved software should be utilized for ASHRAE RTS/CLTD to be accurate. Priority Energy utilizes Wrightsoft RTS/CLTD software for all load calculations.

ASHRAE & ACCA Commercial Duct Sizing

Priority Energy does not rely on rules of thumb. The only way to provide proper air flow and comfort to your guests is to utilize duct sizing software. We will give you a duct diagram from the furnace and air handler to the registers, including all ductwork, connections/fittings and registers. A duct system designed with ASHRAE/ACCA-approved software will give you a quiet air flow system that will extend the life of the heating and cooling system and decrease comfort and humidity complaints.

  • Thank you again and you will be the first person I call if I need additional part or service from your company.
  • I just wanted to send this message to all you and say GREAT JOB!  We had a rough inspection today and passed for the Woodward Ave. house. The inspector told us "if every house I inspected looked like this one I would be out a job".

  • We were so impressed with the amount of information the Priority Energy technicians gave us during our ENERGY AUDIT.  If you are buying a house, I would strongly recommend having them do an energy audit on it, in addition to your usual home inspection.

  • Thanks for a super intelligent and deep seminar expertly handled by a staff which was a pleasure to be around. Lunch was superbly and subtly handled.

    Executive at Medline Industries, IL
  • I have a two story home built in the mid seventies. Lots of temperature fluctuation between the floors. The Aeroseal process dramatically increased the air flow to the second floor. Good experience. The company was very informative, answered a lot of questions.

  • Thank You so much for the super-fast turn around of our Manual J, D and S reprt for the Village of Glen Ellyn. Our original Manual J kept getting kicked back to us for corrections but your calculations/report got approved instantly-no questions asked and no more permit delays!

    Kim, Glen Ellyn, IL
  • Thank you. Truly. I appreciate you taking the time to clarify things for me and then going above and beyond to ensure that my CEUs are handled for our current RESNET cycle. You’ve always been kind to me and this is another shining example of that.

    Richard; Lake Forest, IL
  • On to the Radon issue - Excellent results with Aeroseal!  From 5 + to a .4.  Before sealing like we discussed, I had warm air coming out of the sump basket with the furnace running. Even with the furnace running, it is still pulling air in now.

    Bill; Belvidere, IL
  • Pat was awesome and super helpful! We are experiencing weak air flow in the duct system of our 1950''s home and Pat gave us great recommendations to fix the problem when we do our remodel.

    D. L, Lake Zurich, IL Feb. 2019
  • Priority Energy did an aeroseal for our home. We have had issues with air flow in our kitchen (cold in the winter) and one bedroom upstairs (hot in the summer). After they were complete, there is such a stronger air flow from the vents, that it really makes a difference.

    J.J. Chicago, IL - November 2020
  • Excellent Service and Company to work with - highly recommended and professional!

    T. B. Chicago, IL - July 2020
  • Before we sealed our ductwork the rooms farthest from the furnace were always hotter or colder than the rest of the house. We felt an improvement in air flow to the kids rooms right away. 98% duct leak reduction!

    S. H. Glenview, IL - October 2020
  • The Energy Audit you did on last home was so helpful; we referred to it for years when we made home improvements. I'd like to have you do an audit on my new home now. B. A.
