"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."

Proudly serving the greater Portland and Clark County area since 1952. Our expert technicians install and service the latest in HVAC technology. Call (360) 835-3121 now for an estimate and ask about energy rebates. After hour service available - are technicians are on standby to help you!

"made an appointment because the price quoted to me to diagnose my issue was $89 plus tax, if any repairs are made that would be additional. technician spent 15 min in attic to determine nothing was wrong and then spent remaining time speculating what it could be. After all was said and nothing done my bill came to $307. Technician indicated that it was an extended diagnostic visit. I was shocked and appalled! No tools were used, no repairs were done just the technician speculating on my dime. Contacted the main office and Eva said she would refund me $89 by check. It's gouging and dishonest. If I had known i was being charged by the hour, I guarantee he would have been out of my house 20 mins after he arrived. Im considering contacting the BBB and the attorney general if this is not resolved satisfactorily. I have no problem paying the diagnostics charge of $89 plus tax but not the extended portion."

"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.

GUARANTEED service within 48 hours! We are a small family owned heating and cooling business that strives to be fair and honest with every customer. Our goal is to treat everyone like family and give them the best deal possible while still providing quality repairs.

"Brandon, the service tech, was so professional and honest with every step of the process. My furnace suddenly went out in the morning and by the time I got home in the evening my house was COLD. I called Trusted Choice first and Brandon was the one to answer. He came over right away was able to service my unit and had the heat running again quickly. There prices were reasonable but the level of service and kindness was priceless. Will be recommending this company to all my friends and family. Thank you!"

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

R-value is a measurement that dictates how much resistance an insulation material has against heat flow—or how well it can stop heat from coming and going. A higher R-value, which is attributed to thicker and more dense materials, means the better the insulation performs. There is not one universal recommended value. It depends on climate zones. For example, Alaska, which has a naturally cold and arctic climate, has higher R-value recommendations than the hot and humid Hawaii.

Heat pumps transfer existing heat instead of generating it, using less energy. Compared to baseboard heaters, they can reduce heating costs by up to 50% and provide efficient cooling, lowering electricity bills and carbon footprint.

Services by electricians can quickly get expensive, but there are a few ways you can save money in the process:

  • Bundle multiple jobs done at the same time to save on trip fees or flat fees for individual projects.

  • Get at least three quotes for service to find the best deal.

  • Buy fixtures, switches, outlets, and other materials beforehand to avoid product markup.

  • If you feel comfortable with it, have an apprentice or journeyman complete the work under the supervision of a master electrician. These electricians in training tend to charge less per project.

STC (Sound Transmission Class) ratings tell you how well something blocks airborne noise. It’s a single number that sums up how much sound a material, like a window, can stop across regular speech frequencies. The higher the number, the better the sound reduction. A typical single-pane window hovers around STC 25 (where you can hear normal conversations), while well-sealed, double-pane options can push past STC 45 (which blocks out loud speech and most music). Just keep in mind that STC doesn’t cover everything—low rumbles like bass or thunder can sneak through—so pairing methods are always ideal for the most peace and quiet.

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.
