Description of Work
Premium Efficiency did an energy audit on my home as part of the Oregon Clean Energy Works program. They identified the need for a new heat pump to replace my electric furnace, but unfortunately the contractor I selected chose not to participate in the Oregon Clean Energy Works program and bid from the contractor that did participate was considerably higher, so I didn't take the project further with them. | |However, Premium Efficiency folks were very professional and I would highly recommend them for anyone looking to save on energy usage in their home.

Got estimate for insulation work required in conjunction with installation of ductless heat pump. Estimator arrived on time and was very thorough in checking attic and crawlspace. Estimate was detailed and easy to understand. I ended up going with a different company because their bid was lower and was incorporated into the heat pump proposal I went with.

Description of Work
Company provided estimate for insulation upgrade required in order to get tax credit for ductless heat pump installation.

The first day that Premium Efficiency came to my home a test was performed to see exactly how our home (built in the 1950's) was holding and circulating heat. Casey was thorough and courteous. He then began to seal and insulate (fix cracks/breaks) from the top of the house (in the attic storage space) all the way to the duct work under the house. This was a long and tedious process, but his attitude and professionalism with the task at hand was comendable. Zach came near the end of the first day, and informed us of what else needed to be done. Throughout the whole project Zach informed us of what he was doing, and how it would help with bringing our heat costs down, plus different ways for us to make our home more energy efficient. I love this company because they are local, family owned and employees sincerely LIKE their job and their work. They are small enough to give a very personal experience, but large enough to solve any efficiency problems you may be having. We had the pleasure of working with the entire team at Premium Efficiency and can attest to their honesty, integrity and professionalism.

It went very good. We had a very good experience with them. They were very helpful. They tested the ducting to see if we had leaking duct work. So then they came back to seal it and insulate it. They were here a couple times.
