Commercial Services
We use ACCA and ASHRAE guidelines for load calculation for commercial and light commercial buildings, as well as HVAC duct and system design services for light commercial buildings.

HVAC Load Calculations
Our residential HVAC load calculation services are based upon Manual J®, and this service is required by the State of Florida for all new residential buildings prior to permitting.

Energy Code Calculations
We use EnergyGauge software to determine whether newly built single- and multi-family homes are in compliance with local energy codes, and to plan prescriptive pathways when adding or renovating existing spaces.

HVAC Duct/System Design
The Calcs-Plus team can design a new HVAC duct system for your light commercial building or your home, ensuring proper air flow can be delivered to all areas of the building.

Blower Door Testing
This testing is crucial for measuring the airtightness of buildings, and it’s required in order to comply with Florida Energy Code and obtain a Certificate of Occupancy.

Duct Leakage Testing
After your blower door test, we can complete duct leakage testing to detect and address any leaks in your HVAC system’s air ducts that could reduce energy efficiency and indoor air quality.

Annual Energy Diagnostics
Having an annual energy calculation completed is necessary to estimate how much power is required to meet your building’s needs and to determine the correct sizing for solar or generator power systems.

Acoustics, Noise & Vibration Control
Calcs-Plus works with Vintec Acoustics to deliver acoustic services, noise and vibration control assessment and design, and electroacoustic system design services throughout the continental United States.
