Our consultants can diagnose and solve comfort problems in the home through HVAC performance testing. Air flow is critical to delivering the heating and cooling created by the equipment but can have problems due to restrictions, disconnects, and leakage. Here is a sampling of the test methods we have at our disposal.
Static Pressure Tests
A typical forced-air furnace is designed for .5 iwc, but what happens when the design of the system does not fall into that range? Our consultants can take measurements at different points of air flow to answer several questions.
- Is the size or type of air filter being used too restrictive for the system?
- Is there a blockage of the A-coil?
- Is there a restriction on the supply or return side of the system that is impeding proper air circulation around the home?
Temperature Rise / Temperature Drop Measurements
Does the installation fall within the manufacturer’s specifications? Are there issues with the duct design or speed of the blower causing comfort problems in the home?
With the air handler running or the blower door operating, our consultants can perform zone pressure diagnostics to determine the cause of comfort problems that may exist with air leakage or an imbalance of supply and return air flow.
Air Flow Testing
Using a tool such as a vane anemometer can be a useful way to isolate problems areas of portions of the duct system. Knowing the actual air flow of the system will tell us if the system is operating as the manufactured intended and help pinpoint where to troubleshoot.
