Remote Monitoring Solutions for HVAC

Get an instant alert before a maintenance need becomes a heating and cooling system equipment failure.

Reliable Comfort for Them. Peace of Mind for You.

Keep HVAC systems running smoothly from wherever you work.

Keep Your Cool (or Heat Things Up)

Maintaining a complex heating and cooling system can be a major challenge 24/7. The purpose of a heating, ventilation, and air conditioning (HVAC) system is much more than ensuring you’re efficiently warming or cooling various spaces. An HVAC system also improves indoor air quality (IAQ) by detecting and removing contaminants in the air and making every occupant comfortable.

But what happens when one piece of the puzzle malfunctions? Hopefully, you’re immediately alerted when there’s a problem with anything in your HVAC or HVAC-R systems—ducts, boilers, furnaces, A/C units—and everything in between.

Get real-time alerts for HVAC events that require your attention by monitoring every element of your system with wireless sensors. These commercial and industrial air conditioning and heating system monitors can notify you about abnormal temperatures in ducts, A/C units, or boilers. Our award-winning line of 80+ sensors and remote HVAC monitoring software can also monitor many other variables and symptoms—including motor power draw and vibration. You can even monitor air velocity.

Always know your heating and cooling systems are functioning properly with Monnit Wireless Sensors for remote HVAC monitoring.

Your HVAC System’s Favorite Sensors

Indoor environmental conditions are constantly shifting, but the ALTA® by Monnit Wireless Temperature Sensor can track all of the changes. This makes it possible to chart your HVAC system's fluctuating atmosphere throughout your facilities. With waterproof lead wires measuring up to 100 feet in length, the Standard Temperature Sensor can take readings from deep within your system or monitor the A/C condenser temperature. It monitors thermal conditions between -40°C to +125°C (-40°F to +257°F), automatically logs data, is equipped with 10+ years of battery life, and transmits up to 1,200 feet. It's the right tool for you to run on a Heating and Air Conditioning Split System, a Hybrid Heat Pump System, a Ductless Mini-Split Heat Pump, or a Packaged Heating and Air Conditioning System.

Perfect for remote duct temperature monitoring, you can use the ALTA Duct Temperature Sensor for temporary testing or full-time system monitoring. The real beauty of remote monitoring with Monnit Sensors is that the system reports are delivered to you whether you're at home, in the office, or on the go. The Duct Temperature Sensor can audit the fluctuation of temperature within your HVAC system. Its NTC-type thermistor with UL-listed plenum 8-foot (243.84 cm) lead or cable can be inserted between vents and under small spaces while maintaining a sealed environment. Regardless of what HVAC system you use, Monnit has the right device for you.

An overworked system can trip a circuit breaker. The Monnit family of AC Current Meters is ideal for monitoring your HVAC system's power consumption and forecasting problems before they happen. Our Wireless 20 Amp, 150 Amp, and 500 Amp AC Current Meters can help you predict the maintenance service of every part of your system as essential A/C monitoring devices. For example, voltage ratings for A/C units commonly run anywhere from 15 to 20 Amps, so you can install our Wireless 20 Amp AC Current Meter to measure the power performance of every air conditioning unit. Measuring the current draws of boiler pumps is also a useful application for this sensor. Even if you have a more extensive system that eclipses traditional thresholds, Monnit has the devices right for the job.

Can your current thermostat automatically adjust its temperature thresholds based on whether the room is occupied or empty? Monnit's Thermostat can. It’s an essential monitor and controller of any HVAC system. It’s easy to configure the temperature settings for virtually anywhere in your facilities—from offices to breakrooms to restrooms. With settings managed in the iMonnit cloud-based mobile app, your Thermostat controls are on your phone. This removes the worry of inflicting unnecessary wear and tear on your furnace with a high room temperature.

Boilers are especially prone to "kettling," during which the unit rumbles as a sign it's working too hard. A mount-and-monitor ALTA Vibration Meter can detect these disturbances and alert you when the unit needs maintenance. The Advanced Vibration Meter comes with a cube attached to the lead for greater measuring accuracy. This can save you money in the long run by lowering the cost of bills and extending the boiler's lifetime. Attach one of our Vibration Meters to a blower motor so that you can predict and schedule maintenance before and after hours. Get more operating hours out of your HVACR system by monitoring it with our Vibration Meters.

It’s important to measure airflow or velocity in an HVAC system to optimize performance, increase energy efficiency and cost savings, and maintain proper airflow rates to ensure occupant comfort. A dirty air filter restricts airflow and affects people and the lifetime of heating and cooling systems. Using the Wireless Air Velocity Sensor to measure the speed at which air circulates through a ventilation system could help you forecast issues with a filter that needs to be replaced due to restrictive airflow. The Air Velocity Sensor works by assessing the pressure difference between a lead’s two ports, plus ambient temperature and altitude, to read the airflow speed. HVAC Systems are all about airflow, and Monnit is all about helping you achieve greater efficiency.

An HVAC system's primary purpose is, of course, to push air through a building. An ALTA Wireless Differential Air Pressure Sensor helps ensure that it does. Capable of measuring between -500 Pa to 500 Pa, the Differential Air Pressure Sensor monitors air circulation between two ports and indicates if there is a difference between the readings. This helps technicians and facility managers maintain proper airflow in use cases where an air pressure difference must be optimized to prevent a vacuum when opening a door that could draw dust and other pollutants into that space. Think control, clean, computer, server, and operating rooms. You can set maximum and minimum values in the iMonnit online and mobile app. When there is an unexpected dip or rise in conditions, you’re alerted right away via text, email, or call.

The air we breathe daily matters. To ensure the air circulating through your vents and in your buildings is clean and free of pollutants in the form of various particulate matter (PM), you need the ALTA Air Quality PM Meter. This indoor air quality (IAQ) sensor provides an important function for complex commercial and industrial building air handling systems. The meter measures PM1, PM2.5, and PM10 concentrations in the atmosphere to help determine IAQ and detect the presence of airborne viruses and other harmful bacteria. These IAQ meters provide the necessary information to help HVAC technicians and facility management to maintain clean air for in-building environments. It's your mission to move air through the building, and it's Monnit's mission to make sure that air is clean.
