Air Sealing & Weatherization
If you want to improve the energy performance of your home, one of the most essential things you can do is air sealing.
Air sealing is one of the most important jobs that a weatherization team does. Sealing up the leaks in a house keeps unconditioned air from mixing with conditioned air, whether it is heated or cooled. That means your HVAC system can run less. Along with being more energy efficient, houses without drafts are also more comfortable to live in. A leaky house also allows moisture and other harmful contaminants into your home. Aside from the energy and monetary loss, you are also putting your family’s health at risk.
As referenced in our Home Energy Analysis, weatherization is the key to reducing wasted energy in your home and helps reduce money wasted on your utility bills each month. Our objective is to educate our customers on how their home is using energy, but also teach them what they can do to change unnecessary consumption and help cut money off their utility bills each month.
One of the most effective ways a homeowner can do this is weatherize their home. Weatherization or weatherproofing is the act of guarding the interior of a home from the elements, particularly from sunlight, precipitation, and wind, and modifying an area to reduce energy ingestion and optimize energy efficiency.
The Attic: entrance, insulation, interior walls, ventilation, ducts/seals
Our weatherization process is simple but very effective. It starts with the attic. The attic is one of the largest motives for energy leaving your home. An uninsulated attic is responsible for approximately 15% of your energy loss. During peak Summer season, the average attic temperature is between 140 degrees and 160 degrees.
With that being said, most homes have a pull down door with stairs in a hallways with only a thin piece of plywood between their conditioned air and this extreme temperature. This creates a constant battle with your thermostat to overwork itself and your HVAC to control the temperature in your home. Our weatherization system will provide you with the solution to this problem and energy loss.
We also measure the depth of your current insulation and determine your existing R value. The R-value is a measure of thermal resistance used in the building and construction industry. Energystar.gov recommends the following for certain zones of the United States.
Proper ventilation in your attic is also an important component of your home’s heating and cooling system. Without proper attic ventilation, moisture can become trapped, creating a number of problems: mold, mildew and even reduce the effectiveness of your attic insulation. We personally diagnose any of these problems, if detected in your home.
If you don’t already have one, purchasing a programmable thermostat in your home is one of the easiest and most cost-effective ways to save energy. The Department of Energy states that a programmable thermostat can save up to 15% per year on your heating and cooling costs. During our weatherization process, we will examine your current thermostat and its accuracy. If needed, a new thermostat can be installed and we can teach you how to effectively use it to provide you maximum benefits of the use of energy in your home.
Small amounts of air constantly leak in through the electric outlets and switch plates. If you were to take this air flow per each size of your outlet covers and multiply that throughout your home for each outlet space, you are leaving a space open every day the same size as leaving your front door open each day. We will educate you on how you can solve this problem for only a few dollars.
Hot Water Heater
Your home’s hot water heater is the second biggest appliance energy consumer in your home. Do you know the number one largest energy consuming appliance? It’s your HVAC system. Who would think an appliance we rarely think of comes in close second? During our weatherization process, we educate you on the correct settings for your hot water heater and we will provide you with all of the proper coverings and settings to reduce your utility bills while remaining comfortable and using your energy efficiently. Don’t worry, you will still have hot water for your showers, but you may not realize how much you are wasting currently. Making a minor adjustment could save you as much as 10%! We can show you exactly.
If your refrigerator is more than 5 years old, it uses a lot of energy. This is the 3rd appliance for the most energy in your home. We will review your current settings and teach you how to get the results you need, while reducing energy consumed and money spent each month.
It’s a myth that replacement windows are the key to energy efficiency. Of course, the window company will tell you this, but when you do your research, windows (even new and efficient) still allow a great amount of conditioned air to escape from your home. It is important to have insulated windows with low-e glass to help reduce energy as much as possible. Home Energy Experts can examine your current windows and provide necessary solutions to heat transfer, especially on the east, west, and south sides of your house. If replacement windows are not an option or not in your budget, we will provide you with cost effective solutions right for you, such as quality window film.
Next to windows, exterior doors are one of the largest causes of unwanted air infiltration. Replacing your doors may not be a current option for you either, don’t worry, we have options and solutions to help seal the air without costing you hundreds or thousands of dollars.
Chimney Air Leaks
Did you know that your chimney is one of the largest openings in the home? It’s almost one of the largest culprits for energy loss. During this inspection, we seal up this space while it is not in use and that alone can save you hundreds of dollars in lost energy.
Garage Door Insulation
The garage is often the single largest non-insulated space in a home. When the garage shares a common wall with the main structure, this could result in a significant amount of energy loss through the garage. Weatherizing of your garage doors will help preserve your conditioned air space and also aid in reduction of your energy bill, as well.
All of the spaces listed above are included in our Energy Analysis Inspection and our weatherization process. These are the areas of the home where the largest amounts of energy is lost. Our goal is to educate you on where energy is being lost and how we can correct it, easily and cost effectively.
To properly seal a home, you reduce the amount of humidity and moisture entering in the home by correctly caulking areas and using weather stripping around windows and doorways as needed. By adapting some of these techniques you will be on your way to living in a more energy efficient home.
