"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. "

Here at Able Heating & Cooling, we have a firm focus on providing quality air conditioning and heating solutions for our current and prospective clients. We've been in the business since 1992, and strive to get every heating and cooling job done right. Our customers can count on us to maintain and service their equipment as well, long after an installation is complete. We are an award winning company, and we make every effort to maintain such standards.

"I do not recommend ABLE Heating and Cooling. I have a zoned HVAC system in my home. I called ABLE in June because I was not getting any heating or cooling in my downstairs zone. We set up an appointment for an ABLE tech to come out to my house and look into my problem and do an over all HVAC system check. The tech found that a valve in my zoning system had failed and needed to be repaired/replaced. He also found that my air conditioning unit needed to be replaced. We setup an appointment for a team to come out and repair my zoning valve and install the new A/C unit. ABLE even gave me a discount because I was having both items taken care of at the same time. The team came out and installed and tested the new A/C unit but didn’t spend much time on the zoning valve. Nor did they test it. After they left, I checked and I was still not getting any hot or cold air downstairs. So, I called ABLE to get the problem fixed. We set a date, but the day of the appointment ABLE called and said that the installation manager who was supposed to do my repair had to cover for someone who had called in sick. This left me wondering why the sick guy’s jobs were more important than mine. It became clear to me that fixing my problem was not a priority for ABLE. I cancelled my service request and requested a refund of the funds I had already paid ABLE for the zoning problem they never fixed."

"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."

Energy Efficiency Auditing questions, answered by experts

They’ll use more electricity than the average upright vacuum, but not remarkably more. Most power units plug into a standard 120-volt outlet and don’t have significant power demands. You shouldn’t notice an increase in electricity bills. If you have any specific questions about energy costs, ask your installer as you examine purchase decisions. Larger power units will need more electricity for their suction levels.

A couple of the best ways to find a reputable energy auditor is by determining whether they are HEP-certified by the Building Performance Institute (BPI). This certification will help you narrow down your list of professionals to the most qualified pros with the most relevant experience. 

You can also choose from the Department of Energy’s certified list of energy auditors or Angi’s contractor licensing tool to find pros in your area.

As you look for the right soundproofing drywall for you, you’ll likely come across the Sound Transmission Class (STC) rating. This rating measures a building material’s ability to absorb sound. The higher the number, the better the material absorbs rather than reflects sound, reducing noise transmission. The STC rating for drywall doesn’t mean it’s for the panel itself—it refers to the STC rating for the entire wall system, including the soundproofing drywall.

Energy-efficient windows are judged on their performance according to a few different factors, including heat transfer, air leakage, light transference, and condensation resistance. If you're unsure whether a window is energy-efficient, look for an ENERGY STAR® label from the U.S. Environmental Protection Agency (EPA). If various products, including windows, meet energy-efficiency standards set by the federal government, the EPA issues this label to help consumers identify energy-efficient products.

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