Weatherization or a “Home Seal” is the process of improving the “envelope” of a home. Weatherization helps to better insulate and seal the home, effectively blocking the outside elements and helping to maintain a interior climate. Weatherization includes several key parts.

Duct Sealing

The process of duct sealing can take as little as 3 hours to perform and can make your home a much cleaner and more comfortable environment. Duct sealing is exactly as it sounds; it is the process of tracing leaks and kinks, and sealing all loose joints and connections in the ducting system
Benefits. According to, 92% of homes have leaking or blocked ducts accounting for up to 20% loss in efficiency. Leaking ducts can also bring in dust and carbon monoxide form the attic, causing interior air pollution to be 2-5 times greater than outside air. A properly sealed duct system can eliminate up to 15% of your annual energy costs and will significantly reduce the workload of your heating and cooling system, prolonging its lifespan.
Savings. In the hundreds annually.

HVAC Load Calculation and Inspections

After calculating the homes leakages and natural air flows in CFM, the energy auditor can inspect and assess your current HVAC (Heating and Cooling System) to determine if it is properly sized for your home. While an undersized unit may take too long to cool a home, a bigger culprit for energy loss and discomfort is an oversized unit. That is correct, a HVAC system that is too large for a home will not cool as efficiently as a properly sized unit. This is because a central air system must do two things to effectively cool a home.
Central air units must first it must remove the heat from the home and second, remove the humidity. When a central air unit is too large (too many tons, tonnage being the amount of air in CFM’s the unit is designed to deliver to the home) it will remove too much heat from the comfort zone too rapidly. This will cause the thermostat to turn the unit off before it has processed and removed humidity from enough of the homes internal air. This results in humidity issues in the home and discomfort.
A properly sized unit will both remove heat and humidity from the home because the unit runs long enough to recycle the perfect amount air before dropping the temperature to the desired setting. In addition, a central air unit uses the highest amount of energy when starting and gradually increases in efficiency as it continues to run. In other terms, a smaller unit will run longer but less often, while and oversized unit may turn on and off repeatedly, wasting energy.


Carbon Monoxide Level Testing

Carbon monoxide is the exhaust byproduct of a home’s gas appliances. These may include a range, dryer, water heater, and furnace. Carbon monoxide or CO is a colorless, odorless and tasteless which in certain quantities can be fatal to animals and humans. During the audit, the auditor will walk the home using a CO detector and inspect the homes level of CO in parts per million. Next a calculation is performed to determine if the home requires additional mechanical ventilation or if the home is at acceptable CO levels.
In addition, each combustion appliance is checked for appropriate CO levels to determine it’s burn efficiency. This procedure allows the audit to determine if the appliance is not only in compliance, but if it is consuming the proper amount of fuel and operating efficiently.

Gas Leaks check

In addition to CO testing, the auditor will perform a thorough gas leak check off all gas appliances and indoor supply lines. The purpose of this check is to determine if unwanted gas is entering the living space trough leaks in joints and fittings. In many cases small gas leaks are detected along junctions where joints have become loose over time. The gas leaking into the home from these tiny leaks is wasteful and dangerous, so it is necessary to identify them as soon as possible.
Gas checks are performed with a gas sniffer, which is an ultrasonic tool designed to identify small traces of gas with an audible alarm. For safety and compliance reasons, once a leak is found the auditor must stop work immediately until the leak is corrected.
