"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. "

Energy Efficiency Auditing questions, answered by experts

Depending on the level of audit you choose, a home energy audit will at least include a walk-through of the home to determine visible inefficiencies, but may include testing and a highly detailed inspection and report laying out the home’s inefficiencies and providing recommendations to fix those issues. The audit may also include a review of utility bills and mechanical testing. Consult your home energy auditor about the types of services they provide before hiring.

Yes, barndominiums are energy-efficient as long as insulation professionals properly install quality insulation, windows, and doors. Utility bills for barndo living can be up to 50% lower than those for a traditional home.  Make your barndo more energy efficient by working with contractors and HVAC professionals to strategically place windows, doors, and heating/cooling systems. 

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.

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.

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.

By submitting this question, I acknowledge and agree that Angi may publicly display my name, city, state, and question on the website for professionals and others to see.
