"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. I highly recommend HomeRx for any service they offer that meets your needs. You can’t go wrong. "

"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

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.

While many states require all new construction to undergo blower door tests, it’s not a requirement for existing homes. But in both cases, a blower test helps confirm that the contractor has sealed the exterior, that the type of ductwork installed is functioning properly, and that your home is as efficient as possible.

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.

Setting your AC unit to 78 degrees can, indeed, help you save energy. In fact, according to experts, every degree you turn the unit up could save you between 1% and 3% on your energy bills. That said, turning your unit off entirely while you’re out might actually be less efficient than keeping it on at a higher temperature. Why? The unit will need to work extra hard to cool the house back off again after all those hot hours. 

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