Energy Audits

Sellair’s comprehensive energy audits are performed by one of our BPI certified professionals. They include an assesment of your home (performed with all the appropriate tools like infrared cameras, blower doors, and combustion analyzers) and an action plan to address any opportunities for improvement that are identified.


Increasing the amount or upgrading your existing insulation may lower your heating and cooling costs by reducing heat transfer through your ceiling and walls.

Sellair has experience in all areas of insulation, from basements and foundations, to attics and roof decks. It’s important to remember that we use the “whole-house” approach, which considers an entire structure as a whole when evaluating the type and locations where insulation should be installed. Work done in one area of your home may have an effect on the temperature, humidity and pressure in other parts of the house.

Air Sealing

Air sealing is often over looked but could be the most important thing you can do to improve comfort, indoor air quality and energy efficiency. It is very likely that your home is not properly air sealed, even if it’s a newer home. Unwanted air often penetrates into your home from the least desirable places like your crawlspace or basement, negatively affecting indoor air quality. Moist air traveling between spaces can also lead to moisture control problems which can produce conditions that would attract the growth of mold.

Duct Sealing

Unsealed and un-insulated ducts are often to blame for common comfort problems such as rooms that always seem either too hot in the summer or too cold in the winter. When ducts are not properly sealed, conditioned air leaks out of the ducts before it can be delivered into your home through vents and registers. Un-insulated ducts result in conditioned air that loses some of its energy by the time it reaches the register. This can reduce the efficiency of your heating/cooling system by 20%.


The purpose of proper ventilation is to create a safe environment inside your home. An airtight home can keep indoor air pollutants inside the home, so ensuring that this does not occur is vital to your family’shealth. Ventilation also helps control the moisture level inside your home, which is critical for mold prevention. Our solutions to ventilation issues range from properly venting a bathroom fan to the installation of dedicated Energy Recovery Ventilators (ERV) or Heat Recovery Ventilators (HRV).
