"HomeRx’s sales rep, Bryant, came to assess the attic and crawl space in an older home I purchased. His kind, calm manner of explaining what I needed and how HomeRx would remediate it was reassuring. He told me HomeRx and Energy Trust of Oregon are in a partnership. When I learned I qualified for an ETO rebate, it was so much more generous than I’d expected! HomeRx’s expertise, along with their care, flowed from beginning to end. When I called/visited the office, I felt truly valued as a customer. Alma, Taylor, Samual, Jennifer, Kimberly, and Adan each explained what I needed to know from their unique area of expertise! If there was a glitch, it was fixed to their standards. When I met Jose, HomeRx president, I felt his leadership had a genuinely heartfelt foundation, whether it was in his care for me, his customer, or in his manner of relating with his HomeRx’s teams. I highly recommend HomeRx for any service they offer that meets your needs. You can’t go wrong."

"It was a pleasure dealing with this company from beginning to end. I originally called for an energy audit to find out why the front rooms in the house I just bought were always so cold and drafty. Their rep, Steve, inspected my attic and crawl space and showed me pictures on his phone that showed the lack of insulation in the attic - including a giant hole from an outside wall that was hollow and opened into the attic. The crew who came to do the work kept me informed of their arrival time (they came from Eugene) and did a great job on the work and clean up. But the best part is the difference it has made in the temperature in my house. Insulating an existing house is expensive and I doubt I will ever recoup the expense; but the improvement in the livability of my home made it well worth it."

"The specific project completed on our home was to provide drainage, including a sump pump, in our crawl space and to replace the vapor barrier. Although our particular project was very difficult, including a clay surface below the old vapor barrier, the crew managed to prepare the drainage pipe ditch and lay perimeter drainage pipe. They labored with soil that was either too wet and therefore too sticky to work with a shovel, or soil that was too dry and almost rock hard. After many days of effort they managed to successfully install pipe, sump pump and vapor barrier. In spite of the very difficult conditions with which they struggled to complete the project, the crews who worked on our project were very courteous and professional in the way they did their job. I would highly recommend Josh Lowe's Dr. Energy Saver Home Services."

"John was wonderfully efficient and timely in his work. We love our new system and are very pleased with how quiet the system works. The price was very reasonable. John also walked us through how everything worked and answered all our questions. Totally happy and would definitely recommend Evergreen to anyone--in fact, our daughter and son-in-law also installed the same system for the garage door at their home."

"We got the name of this company basically from random from a list of companies from the Oregon Energy Trust. The work they did with the blower test and energy audit was helpful and done well. It allowed us to understand the energy loss issues in our old home. The issues with this company were with the estimates provided for further work (ex. insulation installation, air sealing, asbestos removal). The quote was difficult to understand as to what work would be included and the prices seemed a bit high. For instance, the quote listed installing attic insulation for about $2200, but then later on listed slashing a vapor barrier on the existing insulation for only $600. The costs of both of these line items were totaled together in the overall bid price; however only upon talking to the company did I find out that these were "one thing or another" options and that they would not be done conjointly. Also, the final cost of the entire work was miscalculated which showed the work to be $3,000 cheaper than it actually would be. Some of the high prices included $175 per gable vent in the attic; I assumed this price included a fan, but in fact was basically just a whole in the siding with a screen installed- keep in mind these would be installed in an area of the attic that has easy access. The insulation quote to blow it in was $400 more expensive than a subsequent quote I received. For blower tests this company was fine, but I took my other work elsewhere."

"They did a real good job. They were real professional. We can now open the garage door from the inside of the house and now it is so smooth that we have to check to see if we hit the button to open it or close it.  Before we used to know when it was opening or closing because it used to make a noise. It helps when you move to a city where you are new. "

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.

Thankfully, LED lights use less electricity than incandescent lights, meaning you won’t spend as much on utility bills by using these light strips. Each 5-meter LED light strip will cost about $3 per year on your energy bill.

When installing a new furnace, it's a good time to consider other projects that can enhance your home's energy efficiency. A great first step is to get a home energy audit, which will identify areas for improvement. Common recommendations include sealing or replacing windows and adding insulation to the attic. These upgrades can help you save money on monthly utility costs. You might also consider installing a smart thermostat to make heating your home more convenient and efficient.

A whole-house humidifier can positively impact energy consumption by improving heating efficiency. During colder months, humidified air feels warmer, which allows you to lower your thermostat without sacrificing comfort. This adjustment can lead to significant energy savings as your heating system works more efficiently. However, it's important to use the humidifier judiciously, as excessive humidity could potentially strain your cooling system in warmer months.

Yes, skylights can affect a home’s energy efficiency, either positively or negatively. Properly installed, energy-efficient skylights with Low-E coatings, double glazing, and UV-blocking glass can help regulate indoor temperatures and reduce heating and cooling costs. However, poorly insulated or older skylights can contribute to heat loss in winter and excess heat gain in summer, lowering overall energy efficiency.
