Stewart Heating & Air Conditioning isn’t just an HVAC contractor to call when you need your furnace or air conditioner repaired. We are a Contra Costa County Home Energy Audit company with a focus on whole home energy efficiency. This means that in addition to normal heating and air conditioning solutions, our customers can use us for home energy efficiency upgrades.

Energy Efficiency Upgrades

When it comes to your home and indoor comfort control, many things work together to maintain comfort and energy efficiency. Insulation, ducting, window types, HVAC equipment – these all play a huge role in how much you spend each month on your energy bills. Energy efficiency upgrades ensure that each portion of your home is functioning the right way.

When your home duct work, furnace, air conditioner, windows and other energy effecting items are working as they should, you save money. It’s just that simple. Our energy audits are the first step towards a more efficient home!

What is a whole home energy audit exactly? This can vary depending on the contractor, but with our  home energy audit service in Contra Costa County, we use modern technology such as thermographic (infrared) and blower door testing to determine where your home is losing energy…and money.

Energy Efficiency Upgrades

Also called Thermographic Inspection, this method uses infrared video and cameras to measure and record temperature variations on the outside of a home. Temperature variations can indicate where your home is losing heat energy. Infrared energy testing plays a key role in our energy audit service, allowing for home energy efficiency upgrades to be more accurate than ever before!

A white, corrugated hose with a blue nozzle sprays white, fluffy insulation into an attic. The insulation is visible as a stream from the nozzle and accumulating in piles on the floor and between wooden studs of the attic framing. The framing consists of several light-colored wooden beams and studs, forming a skeletal structure.

Blown Insulation

Different types of insulation can be blown into walls and attics to provide insulation and noise reduction. Blown in insulation must be done correctly to achieve proper fill and coverage. Our experience in home energy efficiency upgrades means we know the fine details to doing the job right, including probing for blocking and devising the best workarounds. Blown in insulation allows for energy efficiency without destroying existing walls.

A bright red fabric frame, secured in a doorway, houses a large, yellow, circular fan, which is centered in the lower half of the frame. The fan's opening is black with several circular cutouts. Wires from the fan lead to the top of the frame.

Blower Door Test

This involves mounting a powerful fan into the frame of one of the exterior doors in your home. The fan lowers the air pressure inside by sucking air out of the house. This causes the higher outside air pressure to push air through all of the unsealed openings in your home including cracks, non-sealed windows, doors, etc.
