The mechanical system that heats, cools and ventilates your business is typically one of the most expensive line items business owners face, be it new construction, replacing an old HVAC system or simply the operating costs for the heating and cooling of your space. Accurate HVAC design that is properly balance is essential for optimum energy efficiency, durability, humidity control, occupant comfort and healthy indoor air.

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

  • “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 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.

Priority Energy works with:

  • Restaurants

  • Retail Space

  • Schools/Day Care Facilities

  • 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.

  • Anytime I can be a reference for all the great work on my (new) house, please let me know.  Priority Energy is outstanding at what they do!

    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.

    Bill; Downers Grove, IL
  • Duct sealing (with Aeroseal) was the smartest thing I ever did! Our home is sooooo much more comfortable! We were so very pleased with Priority Energy and their technicians!

    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.

National news outlets recently reported that the EPA's Energy Star program recommended "new drastic temperature settings" for home thermostats. We searched the internet and could not find a credible source for this information and so turned to Energy Star directly, for more information.
