"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. "

They know your system when you call, and as a service member, you get quick response service. They confirm appointments by text, text you when they are coming and about to arrive. And you cab track the driver. Always knowledgeable service pros when on site with clear explanations of what happened. Pricing seems very good too. I wish all vendors were like this. 5 stars for sure."

"We replaced our old furnace with a new high efficiency furnace. Shawn came out and helped us figure what to get and gave us 4 options and estimates for each. We chose the third estimate. We set up the appointment, and set the date. Two men came to our home and did the job of removing our old furnace and AC and installing our new ones. It took 2 1/2 days to do the job and it turned out wonderful. The men were great to work with and did a terrific job. They were very polite and fun and answered all our questions. We have used Blairco for about 30+ years, and they come twice every year and do maintenance on our furnace and AC."

We're innovative, hard working and we get the job done right from the science to the site. From our administration team, to the project managers and field crews, our employees are highly skilled and thoroughly trained professionals. We specialize in air quality testing and mitigation (Radon), underground tank decommissioning, sewer inspection & repair, plumbing services, directional drilling, environmental site assessments and environmental restoration.

"I hired Environmental Works on the recommendation of a co-worker. Not only was it the least expensive of the three bids I received but it was also the only company that offered a lifetime guarantee on its work. The entire installation of a radon mitigation system in my home took less than six hours. The company guarantees that its radon mitigation system can keep radon levels below 2.7 pCi/L. A three-month radon monitoring test, completed ten months after the installation of my mitigation system, indicated radon levels at 1.4 pCi/L. I am very pleased with the work that was performed at my home."

Founded in 2007, GreenSavers is a mission-driven contractor committed to helping people save energy. Start with a home energy audit or consultation for efficient HVAC, insulation, or Milgard windows. GreenSavers stands out as a Certified B Corporation™ and multi-year winner of the U.S. DOE’s ENERGY STAR® Contractor of the Year Award.

"I wish I could give less than 1 star. This company took my money and conducted an audit, and after repeated requests on my end for the results and repeated promises on their end to give the results and a promise of a refund, have yet to do so in the 7+ months since the audit was conducted. This was after a multiple month wait on their wait-list to get the energy audit in the first place. I know this company has stellar reviews, but this has been one of the worst experiences with a business I've ever had."

Energy Efficiency Auditing questions, answered by experts

Absolutely! Especially if you have an older home that currently doesn’t have air conditioning where installing ductwork just wouldn't work. No one likes being hot in the warmer months, so if you’re looking to sell your home in the near future, installing a ductless mini-split AC can be a good way to enjoy your home more while you’re in it, boost the return on your sale, and serve as a perk to peak buyers’ interest.

Yes, energy-efficient windows really can make a difference. As long as energy-efficient windows are properly installed and maintained, they can reduce your energy bill and offer significant savings.

While installing your new furnace, you should consider hiring a pro to perform a home energy audit . This audit will give you a handy list of any projects you could undertake to improve your home's overall energy efficiency rating, including replacing or sealing windows and insulating the attic. These improvements can help save you money each month in utility costs.

HVAC systems use the most household electricity. This major and essential system is responsible for heating and cooling your home all year round. Since they operate for a significant amount during the day, it consumes more energy than other appliances. 

Yes, including optimizing settings and suggesting upgrades if needed.
