Home Heating Myths

Myths about home performance proliferate quickly in today’s fast-paced communities, and the East Bay area is no exception. You may have heard some of the following statements from friends, family or coworkers, or on social media. We want to clear things up and share the truth!

Myth #1: New homes are always energy efficient.


air conditioning Oakland CA

Anyone who lives in Oakland, CA knows that the city can get more than just a little hot when the summer months hit. Since it’s more inland than San Francisco, Oakland usually enjoys hotter temperatures overall. Summers are dry and warm, while winters are mild and damp — a Mediterranean climate if there ever was one. For many residents, Oakland summers would be quite difficult to deal with if it wasn’t for central air conditioning.

blower door test El Cerrito Ca

Whether you live in a home that was built 100 years ago or is relatively new, it’s important to take into consideration the potential for air leaks. Air leaks can result from years of wear and tear, but they can also pop up in brand new houses due to a lack of quality control in the building process. Discovering air leaks is the first step toward fixing the problem, and it all starts with a blower door test.

home energy audit

If there’s one thing that just about every homeowner in Moraga, CA can agree upon, it’s that no one wants to spend more than they should on their monthly energy bill. Many go months or even years paying off inflated energy bills without even knowing about it. After all, symptoms of issues related to home performance aren’t always extremely noticeable, especially if you don’t know what to look for.

tankless water heater

For Californians living in Concord, San Rafael and Oakland areas, there’s seldom been a more important time than now to be focusing on saving water. The drought is in full swing, and remedying the problem can only be done if every California resident is on board with limiting the amount of water they utilize each week. There are plenty of things that you can do to save water (we’ll get into that in a moment), but it’s important to also focus on saving energy. This is where tankless water heaters come in.

The warm weather of summer will soon be here, which means east bay area and Marin residents will be relying more and more each day on the functionality of their AC units. It’s no secret that an AC which gets a lot of usage can have a relatively strong impact on your energy bills, and if left to progress, costs can rise sharply.

AC tuneup

Summer hits hard in many parts of the Bay Area. Your neighborhood may be exceptionally beautiful when the warm weather hits, but you’ve got to ensure that you’re keeping yourself comfortable throughout the duration of the summer. Most Californians rely on their air conditioning units to keep them cool, but what happens when yours starts malfunctioning unexpectedly? For this and many other reasons, now is the time to consider an AC tune-up.
