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.

To find professionals who handle energy audits in Glassboro, NJ, contact the team at SPS Mechanical Inc. We specialize in energy-saving solutions for homes.

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. We use blower doors and other advanced technology to give homes thorough performance evaluations.

Benefits of an Energy Audit

Monday, April 22nd, 2013

Saving energy is not only about conserving natural resources, it’s also a way to potentially save money. A professional energy audit is a great way to diagnose and improve the efficiency of your home. SPS Mechanical has an expert team of energy specialists who use a variety of equipment to measure your Sewell, NJ home’s energy usage and discover ways you can improve your energy-efficiency. We’ve put together a few of the benefits of energy audits to raise awareness of how important it is for homeowners.

What Happens During An Energy Audit?

Common energy audit services include using a blower door test to assess the integrity of your ductwork. A blower door is a large fan mounted on an exterior door which pulls the air out of your home and lowers the air pressure. The high pressure outside air will then seek out even the smallest leaks and cracks in your home. This test determines what improvements can be made to your home insulation, ductwork or window and door seals in order to improve your air quality and energy-efficiency. SPS Mechanical will also take a close look at the insulation in your attic. This is one of the major areas of heat loss. In the winter, your hot air will go right through your ceiling if your attic is improperly insulated. In the summer, hot air will sit up in your attic and seep into your home.

Benefits of An Energy Audit in Sewell, NJ

In general, an energy audit is an essential step to take in order to improve your home. Here are some benefits of an energy audit:

  • Save between 20% and 30% on your heating and cooling costs.
  • Reduce your environmental impact.
  • Maximize your home comfort.
  • Save on electricity bills.
  • Increase the value of your home.

Ways to Save Energy in Homes This Winter

Monday, February 11th, 2013

Are you looking for ways to save energy in your Woolwich Township area home this winter? We have a few tips and maintenance tasks that you can use to help save energy on heating your home. Even if you have a high-efficiency furnace, boiler, or heat pump, you could still be saving more money with these guidelines:

  • Consider Upgrading to Renewable Energy
    If you heat your home with electricity or gas, you could save a lot of money in the long run by switching to a renewable energy source, such as geothermal or solar. Heating with a geothermal heat pump can also save on the cost of hot water since these systems can be used to work with a water heater. If you live in an area that is not heavily shaded, consider installing solar panels to help reduce your energy consumption and lower your utility bills.
  • Install a Programmable Thermostat
    With a programmable thermostat, you can adjust temperatures automatically, and many of them are designed to work with multistage heat pumps and dual fuel systems. They are easy to use, and many come with humidity control settings for your whole-home humidifier. 
  • Schedule an Annual Inspections
    The general consensus among heating experts is that heating inspections should be scheduled once a year. You should also have your heating system tuned by a certified technician who is trained to check for any hidden problems, such as a cracked heat exchanger that could lead to carbon monoxide intrusion in the home. They will also test efficiency levels to ensure that your heating system is working properly. 
  • Switch to a Different Fuel
    If you use electric heat, you may want to think about switching to natural gas if it is available in your area. We can install gas piping for new heating systems, whether it’s a furnace or boiler. For homes with existing fireplaces or wood stoves, consider installing a high-efficiency gas furnace or boiler that can be vented through the chimney or vent pipe. As a professional for advice if you aren’t sure what type of fuel is more cost-effective for your home.

If you have questions about how to save energy or how to properly maintain your heater for better performance, call the Woolwich Township heating and home efficiency experts at SPS Mechanical for professional advice.

Heating Tip: Unusual Energy Saving Tips for the Winter

Monday, December 10th, 2012

Are you looking for more ways to reduce your energy and save on heating bills in your Woodbury, NJ area home this winter? Here are some unusual energy saving tips from the home efficiency experts at SPS Mechanical.

Insulate your tank water heater with a water heater jacket.

Part of your heating bills is taken up by heating your water. If you have a storage tank water heater, you can easily find jackets to fit over the tank and reduce standby heat losses, which saves energy and money.

Close the flue when your chimney is not in use.

Chimneys are necessary for proper ventilation in many homes that are heated by fireplaces and wood stoves. If you are not using your chimney, use the damper to keep it closed to prevent heat loss.

Insulate electrical outlets.

Electrical outlets are another hidden source of heat loss. If you stand by your outlet on a wall that leads to the outside, feel for cold air or a draft around it. Adding a little extra insulation behind the outlet or buying a special cover can prevent some of this.

Lower your hot water temperature.

If the thermostat on your hot water heater is above 120°F, turn it down to this temperature. While you may enjoy extremely hot showers, you could save a lot of energy used to heat your water by lowering it even by five degrees.

Use ceiling fans in reverse.

You can save energy in the winter by reversing the direction of your ceiling fans to a counterclockwise direction. This pushes the any warm air that rises back down into the living spaces.

Call the Woodbury, NJ heating specialists at SPS Mechanical if you have further questions.
