An energy audit is a unique experience that gives you the information needed to solve some common symptoms throughout your home. Do you have cold rooms in the winter time that you can't keep as warm as the rest of the house? Is the second story in your home hard to keep cool in the summer? Or are you looking for a way to decrease high energy bills? These are complex problems, that most likely have nothing to do with your furnace or AC (we'll check those too!). The only way to be sure is to have an energy audit completed!

Energy audits, also commonly referred to as home performance assessments, are in depth look into the health, safety, comfort and energy efficiency of your home! We use scientific tools such as a blower door and infrared imaging to diagnose and evaluate the current conditions of your home.

A Blower Door Test is a test to see how air tight your home is. Although it is true that homes need air to breathe, most homes breathe to much! With the Blower Door Test we will be able to determine exactly how much air escapes your home and the adverse effects associated with it.


Carbon monoxide (CO) is an odorless, colorless, toxic gas. Although we stress the use of carbon monoxide detectors, they are only effective at high levels. At the lowest levels, CO detectors are only legally allowed to alert if 30 ppm (parts per million) are sustained for thirty days or more. What does this mean for you? It may mean that you have CO in your home, despite the fact that the it's volume is not at a high enough threshold to set off your detector and notify you. During an energy audit, we will make sure your family is safe by checking the CO levels all the way down to 1.0 ppm throughout your entire home.

Advanced technology allows York Home Performance to see through walls, literally. Thermal imaging cameras allow us to see behind walls, ceilings, and floors to determine where air-leakage is occurring. During the audit, we utilize thermal imaging to obtain a mapping of your entire home while also taking insulation levels, moisture, and construction errors into account.

Gas leaks can occur on inside and outside lines. Larger gas leaks are easier to detect due to the smell. However, leaks that are smaller are sometimes quite difficult to smell, and thus very dangerous. During the energy audit, we'll properly check all exposed lines to ensure your family is safe.
