The Problem
HVAC units typically consume 30-60% of a commercial building’s electricity but output little or no data about system health or alarms.
ASHRAE (The American Society of Heating, Refrigeration, and Air Conditioning Engineers) estimates that 60% of commercial floor space is served by rooftop air conditioning units.
ASHRAE also estimates 50-67% of these rooftop units are improperly charged with refrigerant (Freon) or have airflow issues.

The Stakes
A 2010 Purdue University study put a price tag on poorly charged units:
“An undercharge of 25% would cause an average penalty in SEER of about 16 percent and a cost penalty of $100 per year per ton of rated capacity for typical electrical rates.”
“An undercharge of 25% would cause an average penalty in SEER of about 16 percent and a cost penalty of $100 per year per ton of rated capacity for typical electrical rates.”
That puts a single undercharged 20-ton unit (more common than not) wasting $2,000/year.
The Solution
We need information - LOTS of accurate, real-time information.
The Frontline Defense
At the most basic level, every Enerfit comes with an EMT (Enerfit Monitoring Tool) that resides in the unit and shows critical unit information and alarm in real time.
Service techs no longer need to immediately hook up their gauges when they start the troubleshooting process. With the EMT, they immediately get far more accurate real-time information.
On V2 units, the EMT allows technicians to go one step further and easily manual cooling stages on/off, heating stages on/off, enable/disable the economizer, and manually control the fan speed and OA damper.
BAS Integration Out Of The Box
Have a unit controller you love? Our V1 product allows your existing thermostat/controller to make heating and cooling calls. Enerfit just observes and maximizes your savings in real-time.
Enerfit V2 is a next-gen BAS system built into your HVAC retrofit. Thousands of our controllers have been integrated into popular BAS front-ends.
V1 or V2, Enerfit speaks industry standard, open-protocol BACnet. We use plain text and standardized nomenclature to make integration a snap via BACnet IP or BACnet MS/TP.
Both technologies are included standard on all of our controllers and come at no additional cost.
Got 10 units on a roof from five different manufacturers? Enerfit V2 has been a favorite with customers looking to standardize and simplify unit control. Some customers even purchase new barebones/whiteboxed basic units and add Enerfit V2 as the controls package in the field on Day One.
