Some comfort and indoor air quality issues we encounter bleed over from areas that we might be unfamiliar with. The most common are the influences of building construction, like leakage and insulation.

Many new self-contained fractional horsepower refrigeration systems will be shipped from the factory with no service access ports.

Unless you know where to start, adding air diagnostics to your HVAC company can seem daunting. Here are eight steps you can take to help add air diagnostics to your service offerings.
