Is a Home Performance Evaluation the Same as an Energy Audit?

Wednesday, December 17th, 2014

Have you been looking to save some money on your utility bills recently? If so, you may have been mostly searching for ways to cut back on some of the components of your home that utilize the most energy. But limiting essential appliances like heating and air conditioning systems or a washing machine or dryer is a terrible way to save some money, leaving you uncomfortable and without some near necessities for the home.

When you’re looking to save a lot of money over the course of the next year and beyond, many contractors recommend scheduling a home energy audit. But if you’re having trouble locating a company for the job, there’s something you should keep in mind: a home performance evaluation is the same thing.

To schedule your home performance evaluation today and find out where your home is losing energy, and to learn more about our comprehensive energy audits in Deptford Township, call the experts at SPS Mechanical Inc.

What Happens during a Home Performance Evaluation?

During a home energy audit a professional will examine your home in order to help you discover which areas can be improved to help you to save over time. There may be a number of factors contributing to excessive bills. You may have too many minor leaks and cracks in the house, poor insulation, or outdated HVAC equipment, but in any case you’re almost certainly spending at least a little more than you need.

A home performance evaluation generally begins with a blower door test. During a blower door test, every door and window in your home is sealed shut, and a large fan is placed in the front door to lower the pressure inside of the house. After, professionals can use a tool to detect where air is leaking and can let you know where any sealing is required.

After the blower door test, the technician may also perform one of many different services including a thorough inspection of the parts of a home that are prone to energy loss. You may discover that you could use some insulation to keep your home comfort system from becoming overworked. In the majority of homes in the U.S., a lot of energy is also commonly lost in leaky ducts. And a home performance evaluation can also help you discover if your ducts are contaminated and require a routine cleaning.

What Are Blower Doors and What Are They Used For?

Wednesday, August 20th, 2014

How energy-efficient is your home? You may not know it, but your home might contain numerous air leaks where heat escapes during cold weather and enters during warm weather. This places a strain on your HVAC system and leads to discomfort. Those same air leaks can also bring in moisture and lower your indoor air quality.

The best way to evaluate your home’s airtightness is to schedule an energy audit. An audit, also called a home performance evaluation, will systematically locate where your home is losing energy and find the best ways to seal and insulate it so you’ll save money and protect your indoor environment.

The key tool for an energy audit: the blower door

To evaluate the airtightness of a home, auditors use a device called a blower door. The standard blower door mounts within the frame of an open door, sealing completely across the aperture so there are no leaks around it. Within the blower door is a large variable speed fan and a pressure monitor called a manometer. During an energy audit, the technicians attach a blower door to the front door of a house. They then make sure that all other doors and windows throughout the house are shut. The blower door fan activates, and it draws air from inside the home to depressurize it; the manometer measures the difference in pressure.

Once the blower door has lowered the pressure inside the house, outside air will rush in through any opening, such as gaps in building material or insulation, and around poorly sealing windows and doors. The auditors move throughout the house and use smoke pencils to detect where air is rushing to enter air leaks. After a blower door test, the auditors will have a good idea of where a home lacks integrity in its heat sealing, and they can start to investigate specific areas.

Energy audits consist of more than the blower door test: excellent auditors will perform an extensive walk-through of the building to note specific points of energy loss and gain. They’ll test the HVAC system and the sealing along the ventilation. They’ll see if all your major appliances (laundry machines, refrigerator) are working at their most efficient. Once they’re done, they will report to you with a list of where your home could improve its efficiency and suggestions on what you can do.

We suggest that everyone have an energy audit done for their home at some point. If you feel that you are paying more on your utility bills than you should, call SPS Mechanical Inc. and ask about our services for energy audits in Glassboro, NJ.
