Energy Efficiency Auditing questions, answered by experts

You can check your home's humidity in a few ways. A simple option is to use a hygrometer, which you can find at a hardware or big box store. Your smartphone may also have an app that can measure humidity. Modern thermostats, particularly smart thermostats, are also able to measure humidity levels.

Costs depend on pipe length, accessibility, and whether additional services are required.

Audits include inspecting insulation, HVAC systems, windows, and appliances to identify energy inefficiencies.

A home energy audit costs about $420 on average, ranging from about $100 to $2,250 or more. Cost factors include the size of your home, the type of testing, and the thoroughness of the audit. A Level 1 walk-through inspection will cost between $150 and $200 for the auditor to point out inefficiencies in your home. On the other hand, a more thorough Level 3 audit with testing and a detailed report will cost about $900.

R-value is calculated by dividing the thickness of an insulation material by its thermal conductivity. The material's composition and density influence thermal conductivity. Materials with lower conductivity values provide better insulation. The higher the R-value, the better the material is at insulating, helping homeowners select insulation that meets the energy needs of their climate and home layout.
