"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.

Energy Efficiency Auditing questions, answered by experts

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.

Provide utility bills and clear access to all areas of the home, including the attic and basement.

Wood windows fall in the middle of the window frame materials when it comes to energy efficiency. They’re more insulating than aluminum and vinyl, but they aren’t as efficient as fiberglass or composite frames. If you love the look and lifespan of wood windows and want to maximize efficiency, you can upgrade to double-pane or triple-pane glass and consider window tinting and low-emissivity (low-E) coatings to minimize heat transfer.

Expert installation optimizes insulation properties, cutting energy costs and enhancing home comfort year-round.

The best way to save money on home heating oil is to get large deliveries in the summer months when the prices are lowest. However, this method will only work if you have a separate storage tank or an unusually large primary tank. You can sometimes save money by opting into a delivery contract, as some companies offer set prices that they believe will sit at the average cost over the contract term. If the price of oil rises, you could enjoy some savings, but keep in mind that you might also pay a bit more if the price decreases.
