"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. "

"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."

"Had Affordable Home Remodeling replace several old aluminum windows around our house with modern storm windows. Very knowledgable, and compared to other bids, the price was reasonable.

"Contacted them regarding an issue with an LG mini split where it's leaking refrigerant somewhere. Over the course of the year, they've sent someone out to look - charged me for that, couldn't find a leak, charged me for that filled it, still a leak, came back, charged me for that, couldn't find the leak again, replaced parts within the system that apparently were not the cause of the leak, I guess without being able to determine the actual cause, charged me for that. Still a leak, and then requested another leak finding search where the next thing they want to fix is another expensive part. Currently, I'm out $4000 that i've spent with them so far, and still have a non-functional AC unit with a leak. If I continued with their recommendations without pushback, I'd be out at least $7000 before all is said and done. For a leak in a mini split. Will update if this ever gets resolved by them."

Energy Efficiency Auditing questions, answered by experts

Smart home upgrades can be worth the money. Several upgrades, including smart thermostats and ceiling fans, can help reduce your energy bills. Others make life more convenient, freeing up your time to do what you love (or get more work done). And some smart home upgrades, such as entertainment systems, simply make life more enjoyable. All are worthy causes.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

Installing weather stripping or upgrading to insulated panels can improve efficiency.

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.
