"I contacted HW as a possible backup contractor. Even with that understanding, Al Lien came and independently reviewed the damage and said HW would be happy to hold their position as a contingent contractor. Very impressed with their forthright attitude and professionalism. Other contractor did come through. But I am certain I will use HW in the future. Thanks Al!!"

Energy Efficiency Auditing questions, answered by experts

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

Yes, Tesla Powerwalls are worth the upfront costs, as you can recoup your investment within six to eight years. Plus, they provide peace of mind that you'll have power during a power outage, and, depending on the system you install, you can become energy-independent. While they may be more expensive than other solar power systems, they offer higher battery capacity and lifespan.

There is no blanket figure for a residential home’s electrical load, since load varies by the size of the home, how many appliances are used, and the efficiency of their electrical systems. Typically, however, it’s safe to assume 40 to 60 amps is the average electrical load of a residential home. 

You can check your home's humidity in a few ways. A simple option is to use a hygrometer, which you can find at a hardware or big box store. Your smartphone may also have an app that can measure humidity. Modern thermostats, particularly smart thermostats, are also able to measure humidity levels.

There are a couple of ways you can save on the cost of your home energy audit. First, find out if you qualify for programs like the Department of Energy’s Weatherization Assistance Program for low-income households. Next, check with your local utility company to find out if you qualify for any local rebate programs to offset the cost of this helpful service.
