"Quickly figured out that problem was a frozen drain pipe causing its sensor to shut down the furnace. Fixed with a temporary drain tube replacement to a bucket below. BRILLIANT!!! Very satisfied. Even showed me how to reconnect when the main drain tube thaws out so I can save another service call."

"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

Dehumidifiers typically use 300 to 700 watts of electricity per hour, whereas portable dehumidifiers use about 40 watts per hour. The exact amount of electricity your dehumidifier will generate depends on its capacity and energy efficiency. Generally, higher-capacity dehumidifiers generate more electricity than lower-capacity units, but they also usually have better energy efficiency over the long run.

A home energy audit costs about $420 on average, ranging from about $100 to $2,250 or more. Cost factors include the size of your home, the type of testing, and the thoroughness of the audit. A Level 1 walk-through inspection will cost between $150 and $200 for the auditor to point out inefficiencies in your home. On the other hand, a more thorough Level 3 audit with testing and a detailed report will cost about $900.

Fans reduce peak cooling loads, lower air conditioning energy expenses by expediting heat exit, and enhance natural airflow throughout the home.

ENERGY STAR®-certified windows are the most energy-efficient windows on the market. This certification means that the window meets strict efficiency guidelines set forth by the Environmental Protection Agency. While they might cost more upfront, they can save you money on your energy bills in the long run. ENERGY STAR®-certified windows lower household energy bills by an average of 12% annually.

Dryers are designed to use as little electricity as possible, but power is still required to run the motor that turns the drum and to heat an element that pumps hot air. Eco devices are available and may lead to cost savings in the long term, but you should run the figures before committing to an eco-friendly device as they are often much more expensive to purchase.
