HVAC Inspection Equipment: Humidity Gauges, Infrared Thermometers and Wind Meters

There are many reasons to have your HVAC system inspected regularly. A properly functioning system can save on heating and cooling costs, to prevent the growth of mold and for safety. Unfortunately, for property managers, HVAC system problems aren’t often visible and require specialized precision measurement tools to determine.

A humidity sensor, for example, determines a building’s relative humidity, which can lead to more efficient identification of equipment malfunctions. And infrared thermometers make heating and cooling problems, like a poor seal or improperly fitted furnace, easier to detect. Building and home inspectors, facilities managers, HVAC inspectors and electricians all use these specialized devices, because they provide quick, accurate measurements.

Infrared Thermometers for HVAC Inspection

The best infrared thermometers are often called temperature guns, because you just point them at a source to find the temperature. That makes these measurement tools extremely versatile. Using infrared thermometers, building inspectors and facilities managers can gauge temperatures in hard-to-reach places, like behind a piece of hardware.

Infrared thermometers are also referred to as laser thermometers, because they often use laser technology to measure the infrared energy emitted by a source. From that, they can determine the temperature. Generally, IR thermometers are used to gauge the temperature of a home or building’s heating system, like a hot water heater or furnace, as well as electrical and plumbing equipment.

Another common application: Infrared thermometers can be used to improve a building or home’s energy efficiency. Cold air leaks around HVAC systems and other areas where heat can be lost are easier to determine with infrared thermometers.

Humidity Gauges for HVAC Inspection

Humidity sensors are another important tool for property inspectors. Essentially, these gauges measure the relative humidity of an environment, and they have a wide application, they’re used in meterology for instance.

In building inspection, humidity gauges can help detect a few issues. First, they can determine airflow issues in an HVAC system; low relative humidity, for instance, might mean that an HVAC system isn’t delivering enough air to a particular area. In addition, humidity sensors can determine when relative humidity is higher than normal. When it is, the risk of mold growth is greater, because mold thrives in moist environments. This can cause a variety of problems, from wood rot and corrosion to impaired worker health.

Airflow and Wind Meters for HVAC Inspection


Finally, wind meters are used to determine the airflow from a heating or cooling vent. When placed in front of a heating vent, for example, one of these handheld devices measures wind speed, and using this data, HVAC inspectors can determine the consistency of hot or cold air. Thus, if an air conditioner isn’t providing enough air, or the flow isn’t consistent, that problem is very easy to determine.
