"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. "

Dvac Heating & Air LLC, we can offer the best services and prices. Establish business since 2014, we offer residential maintenance plans, install ductless heat pumps, furnaces, central air heat pumps, electrical services, panels, lights, outlets, hot tubs, and other. Give us a call for your HVAC and electrical needs today.

"Avoid working with DVAC at all costs. When I initially requested a quote for the installation, I specifically asked for a 3-ton high-efficiency heat pump. Unfortunately, the experience with DVAC has been nothing short of frustrating. They began by stating that extensive work needed to be done, charging for it all upfront. However, when it came time to install, they drastically lowered the quality of the equipment, gaslighted me, and lied about what was being provided. Hidden charges surfaced right after my existing system was removed. The issues I discovered included but not limited to: 1.The installed heat pump is only 2-ton heat pump instead of the required 3-ton heat pump stated in the estimate. 2.The furnace provided is of lower quality than what was agreed upon. 3.The ducts installed are too small for the system. 4.The electrical cable used may be undersized for 3-ton heat pump. 5. All works were unpermitted. Throughout the project, I repeatedly verified the permit status with DVAC, including on the installation day (8/15). They assured me everything was in order. However, on 8/20, I confirmed with the City of Kirkland that none of the work had been permitted—a clear violation of both city regulations and our contract. Given these serious issues, I requested a full refund and the removal of all unpermitted work. DVAC refused to comply with the contract and denied the refund. If there were a zero-star option, I wouldn't even give them a single star."

Energy Efficiency Auditing questions, answered by experts

STC (Sound Transmission Class) ratings tell you how well something blocks airborne noise. It’s a single number that sums up how much sound a material, like a window, can stop across regular speech frequencies. The higher the number, the better the sound reduction. A typical single-pane window hovers around STC 25 (where you can hear normal conversations), while well-sealed, double-pane options can push past STC 45 (which blocks out loud speech and most music). Just keep in mind that STC doesn’t cover everything—low rumbles like bass or thunder can sneak through—so pairing methods are always ideal for the most peace and quiet.

If you install LED bulbs, they will use much less energy than incandescent bulbs. LED light strips also use less power. Battery-operated puck lights use no electricity at all, but you will need to replace the batteries as needed. They are beneficial if your power goes out, too, as they will remain on as a light source. 

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.

Provide utility bills and clear access to all areas of the home, including the attic and basement.

Keep the unit full but not overloaded, ensure door seals are tight, set correct temperatures, and avoid frequent door openings. Position the appliance away from heat sources for optimal performance.
