"Terrible company that fights with its customers vs. taking ownership of their mistakes. I dealt with Rob, the owner, because the furnace they installed didn’t fit where the old u it was. Also, my 2nd furnace mysteriously lost power to at the same time my new furnace was installed, yet they claim they have absolutely nothing to do with it. The owner bullied me for full payment, claiming breach of contract if I didn’t pay in full, even though the job was done poorly, the furnace closet door won’t close and my other furnace doesn’t work. Looking at his Yelp reviews, you can see that other customers have been bullied as well. The technicians are nice, but the owner will always deny any wrongdoing on their part. I had to pay in full and now am hiring other vendors to fix Revival’s issues."

"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. "

Hello my name's Joshua, I have been working on cars for the better part of my life. I started working on cars when I was a child, with my father and grandfather, and am now a father of three myself. With the training from my father, and his, I have continued to teach myself and have become quite the auto mechanic. I started my own mobile auto repair company this year after deciding that I wanted to create something that my children could take over someday. Everyone I have done auto repairs for has had a great experience and was more than satisfied with my work. My knowledge and efficiency have shown through in every job I have completed. I take great pride in the work I do and believe in honesty. When speaking to customers, I will take the time to explain the why's and how's of their car problems, give them all their choices for the resolution of the problem and provide guidance on prioritization, based on both mechanical and financial need. I welcome the customer to watch my work and often offer to teach them how to do it, in an effort to help them with future repairs. I believe in doing the job right the first time and guarantee my work for 60 days to make sure I do every job to that standard. My labor price is one of the lowest in the Portland area and I take great pride in being fair and helping people out. I do all repairs for my clients at the most convenient location for them, I will come to you wherever your car needs me. I do not mark-up the prices of the parts which offers the customer another financial advantage over in house automotive shops. I receive a business discount at select auto parts stores, which I pass directly onto the customer, as yet another way I intend to offer the best work at the best price in the Portland area. I offer a free quick estimate by phone, so give me a call and let my family help yours in a time of automotive need. Please and thank you.

Elemental Energy is a highly experienced solar PV design and installation firm for residential and commercial clients throughout Oregon and Southern Washington. Locally owned and operated right here in Portland, we pride ourselves on providing creative solutions to your home or business energy needs, and aim to make the process of going solar simple and efficient.

"We had our house reroofed in January 2025. I got several bids, all came in about the same cost. We ended up selecting Elemental based on their knowledge of our existing system (Enphase) and their great description of what was going to happen. They coordinated with our roofing company to make the whole process seamless. The technicians that did the work were very professional and did a great job explaining what they were doing. The original mounting hardware had leaked a bit requiring our roofer to replace about 10 sheets of sheathing. The technician explained how the new mounting system would protect against leaks. They also applied some additional caulk to ensure a good seal. I would highly recommend Elemental for anyone that needs a removal/reinstall for reroofing."

Energy Efficiency Auditing questions, answered by experts

While parts of the appraisal are out of your control, there are some things you can do to potentially raise the home’s value. You can make necessary repairs and upgrades before the appraiser visits—an appraiser can only value what is currently part of the home, not its potential. You can also provide the appraiser with the cost of recent upgrades. The appraiser will likely increase the value of your home by about 50% or more of what you paid for those improvements.

Electric bills tend to be lower in spring and fall because people use less electricity during these seasons. Milder temperatures allow for less use of heating and cooling, unlike during winter and summer, which usually bring more extreme temperatures.

You'll likely need more than great home staging to sell your home. Now is a great time to get to work on the curb appeal of your home . Hire local exterior painters and landscapers to coat the exterior of your home and bring it new life with some sprucing up.

Depending on property size and audit scope, costs range from $200 to $600.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.
