Revolutionize HVAC Monitoring and Energy Efficiency

• Which temperatures are saved to the cloud? In-Duct air before AND after heated or cooled.
• Changes can identify loss of refrigerant or other compressor or related problems.
• Outdoor temperature at the time of in-duct measurement, and the forecasated highs and lows for that day.
• The ambient temperature at the HVAC air handler, such as on the roof for commercial or attic or basement for a home.
• The most important indicator of a current or future problem with an HVAC system is a continual upward or downward shift in the temperature of its output air.
• Long term records of the relationship between the various temperatures provides valuable insights into the degradation of HVAC performance, and historical data processing for energy saving actions or recommendations.

Air Flow Rate monitoring is standard for commercial buildings, and optional for residential housing.

• Probes monitor Cubic Feet/Minute (CFM) air flow inside the duct.
• Using typical flow rates based on HVAC tonnage, or the owner’s specific HVAC unit, HVAIC compares expected flows to actual flow.
• Flow too low can lead to too cold or frozen evaporator coils.
• Flow too fast could lead reduce the ability to dehumidify air, higher blower electricity usage and a noisier system.

• HVAIC measures the amount of AC electrical current being used by your air handler.  This provides relative data of total HVAC energy consumption by season and the temperature ranges.
• As historical data is obtained by HVAIC over each day of each season,  analysis will increasingly be able to predict maintenance needs and provide insights into how best to set thermostats for energy reduction.
• Future plans for HVAIC include integration with one or more thermostat brands to automously adjust thermostats to “comfort zone” temperatures preferred by the business and home owners.

• In addition to energy, pressure, current and temperature, the run-time of the HVAC (the duty cycle) is stored with each data capture.
• Because the overall HVAC system configuration remains constant, HVAIC focuses on tracking its relative performance over time. Knowing the exact kilowatt (kW) cost for your location isn’t necessary to identify opportunities for savings—reducing energy use naturally lowers costs. Since duty cycles determine total kW consumption, HVAIC’s monitoring of high, low, and average values indicates whether your energy expenses are trending up or down.

• Heat pumps become less energy efficient below about 40F.
• When it cannot maintain the set thermostat temperature, auxilary heating coils (AUX) active.  A Google AI search shows that this can result in a 50% or higher energy usage.
• HVAIC’s monitoring of current can detect the higher current draw and thus track and report the times of use for AUX activation and its duration.
• An alert or report can be sent to the homeowner.  The homeowner could then lower the thermostat setting at the times shown for AUX use to reduce the frequency and duration of its activation.

• Outside air temperature determines inside air temperature changes.
• Outdoor wireless thermometers are unreliable.  Too often they are placed in areas where sun, heat loss from the home or heat from the outdoor HVAC unit influences the measured temperature.
• HVAIC records a weather service temerature for the home’s Zip Code whenever HVAIC sends duct air temperature to our cloud.
