There’s no such thing as a one-size-fits-all solution to your home's issues. Your home is complex, and in order for it to work right, we need to look at the big picture.

I'm well-versed in the principles of modern building science, providing a wide range of services that can make your home more comfortable,  more efficient, and healthier. Whether your home is too hot or cold, your indoor air quality is suffering from vog or mold, or your energy bills have gone through the roof, we'll discover the solutions you’re looking for.

As a licensed contractor in the state of Hawaii (Lic.#CT-36526), Terrawatt does many things:

Home Energy Audits

There are a number of home comfort and efficiency issues that are obvious, such as high energy bills or inefficient cooling systems...but other problems may go unnoticed for long periods.  That's why it’s important to do a full inspection of the home to isolate any issues that are affecting your home's performance.  Terrawatt performs comprehensive home energy audits to gain a thorough understanding of what’s going on, which leads to proposing more confident solutions.


Insulation is one of the most important elements of year-round home performance. It keeps cooled homes cool and warmed homes warm in the winter (yes, winter).  90% of homes in America are under-insulated, which can result in huge energy bills and an uncomfortable home.  If you're thinking about AC...insulate first!

Air Sealing

Cracks, gaps and enormous holes let large amounts of energy escape. This is especially true of older, draftier single-walled homes.  Finding the holes, and sealing them, is the solution and it works hand-in-hand with insulation.  Hawaii has an airtightness requirement for a reason.  Are you shopping for an insulator?  Ask if they do air sealing too.

Indoor Air Quality & Dehumidification

Got strong, odd smells?  Mustiness or mildew?  Does the wind shift and fill your house with odors?  Indoor air quality problems are common on the Big Island and they're be detrimental to your family's health.  Fortunately, most indoor air quality issues can be solved after a thorough investigation to uncover the source of the problem.

Cooling & Heating

Our heating and cooling systems keep us comfortable throughout the year.  As with any type of equipment, however, these systems must be maintained regularly in order to operate smoothly.  Terrawatt can help ensure that your HVAC equipment is operating at peak performance, and I’ll help guide you on purchasing new equipment should you be in need of an upgrade.

Pre-Solar Inspections

Have you heard the term "Reduce before you produce?"  A solar electric system can do wonders for your energy bill.  But what if you have trees in the way?  Or not enough roof area?  Or you only have north-facing roofs?  If a solar system doesn't cover 100% of your energy bill, you're leaving money on the table.  I'll help you find the energy wasters in your house and reduce your HELCO bill before you get on the solar coaster.  And then, when you'll be able to get a smaller system, saving you money.
