"Mark and his guys helped us install a new AC last summer. They arrived on time and did a great job! So when I was looking for someone to do the maintenance of our furnace, I called them. Todd went above and beyond my expectations. He finished the job and even helped fix my hinge. Both Mark and Todd strike me as very genuine people. And I would definitely hire them again!"

"I had my sump pump replaced. Blaine explained all my options. I decided to have him replace the pump, install a deeper pit, replace and pipe the discharge line and tie it into my gutter downspout. He and his co-worker arrived right on time. They were friendly, polite and made sure to explain all the work that they were doing. He made sure that the pump operation could not be heard from inside the house. I highly recommend Seatown and plumber Blaine in particular"

"The first technician determined the gas furnace is good and the air duct is the problem. After I checked the air ducts in my crawl space and found no problem, I called Air Masters on what I found and it sent service technician out again for free. This time the second tech said I have a plugged-up heat exchanger. I decided to replace the gas furnace instead and the problem fixed. So the only thing I know is my old furnace was bad."

"Our old gas furnace died during the series of snowstorms in February. Stephan came out the day after we called, to give us the bad news that the unit was so old, no replacement parts were available so the whole thing would have to be replaced. Not really surprising given the age of the unit. He also showed me where the water heater (of similar vintage) was corroding around the outlet pipe, so was also in need of replacement. Kris came out within a couple of hours to look over the house and recommended a couple of options. We were leaving town so installation was delayed a couple of days; otherwise we could have had everything done within 48hours of the initial call. The crew that showed up to do the installation (sorry I forgot your names) showed up promptly at 8AM, worked throughout the day, and left our basement cleaner than it started out."

"Excellent service! We had Bassett replace all the flexible ductwork under our house with metal ductwork. (Rats had eaten through the flexible ducts). David, Isaiah, and Jiwan were very professional, courteous and clean. They arrived when they said they would, kept us updated as to the work and cleaned up when they left. The owner, John, gave us a good, clear estimate ahead of time and explained what they would do. They were extremely well priced. I would say the only negative was getting a call back but keep trying. They are worth it and more! We interviewed three other companies. They are the best!"

"Evergreen installed a new hybrid heat pump system in my house. After researching the options, Evergreen was not only the most reasonable price, but they also scoped out a hybrid system where they would install new duct work and a single air exchanger in the attic and a minisplit in the basement. Scott, the sales person, did not try to upsell me on number of zones (others tried to get me to get 2 units in the basement) and after 2 months with the system, the single unit in the basement is heating the whole basement to our needs. All this was done at a price still considerably lower than the "standard" system price being offered by one of the bigger, similarly named companies. Evergreen was also the only company to propose a hybrid system where they would install a single exchanger in the attic and run new ceiling ducts to the rooms. This was appealing because we don't need to have the cassettes in each room and we didn't need to line the outside of the house with conduit for the cassettes (also the bathroom gets heat, too). Scott was great to work with, answered all my questions, and did his best to size the system correctly. Installation was smooth. There was a small hiccup where the installer accidentally broke a basement window, but Evergreen squared it away. Don and his team were great and the inspections passed. After install support has been great. Denise has been responsive to my questions. Overall, the experience was great with Evergreen and I highly recommend them."

"I purchased a new Navien NPE-240A2 Tankless Water Heater and had it installed. I'm loving the new water heater. It replaces an old Noritz tankless that died just before this installation. The on-site estimate was what sold me. Ken went through all the details and answered a lot of questions from me. Zachary came out with Austin and performed the installation just like I discussed with Ken. Zachary kept me in the loop throughout the installation to ensure I was in agreement with how it was going. Zachary always had my interest at heart and ensured no corners were cut. The installation is much cleaner, and more correct than the previous tankless company did. Zachary even listened to my concern about the astectics of the exterior exhaust and quickly found an easier and cleaner looking way to address my concern. He also removed an old recirculation pump and replaced a new main house shutoff valve. The entire area was treated respectfully and left cleaner than they found it."

"Allred is THE best. I had mini-split AC/heat installed almost a year ago. I love it and it's saving me significant money over using my central heating system. And no more hassle with portable air conditioners. I should have done this years ago. Even better is the 5 star customer service. Last week I had difficulty turning on the AC for the first time since last summer. I urgently called David on a Sunday. He immediately dove in to get me scheduled. Sebastian called me before making an on-site visit. Patiently walked me through a simple troubleshoot and shazaam! I turned right on. A+++ to both of them."

FAQs for ducts & vents installation and replacement projects in Seattle, WA

Return air vents aren't required in every room, but proper placement is essential for system efficiency. According to industry standards, you'll need one return vent for every 100 to 150 square feet of living space. Ideally, each room would have its own return vent, especially larger rooms exceeding 100 square feet. 

Without adequate return airflow, your HVAC system works harder, energy costs increase, and comfort decreases. A professional assessment can determine the optimal number and placement of return vents for your specific home layout.

Signs that your home needs additional return air vents include rooms that feel consistently stuffy, noticeable temperature variations between rooms, doors that slam shut when the HVAC system operates, or unexpectedly high energy bills. Excessive dust accumulation around supply vents can also indicate inadequate return airflow. 

If you experience these issues, consulting with an HVAC professional can help determine if adding return vents would improve your system's performance.

Supply vents deliver conditioned air into your living spaces, while return air vents draw room air back to your HVAC system for reconditioning. Supply vents push treated air into rooms, while return vents pull air from rooms back toward your heating and cooling equipment. 

Both components are essential for proper air circulation and system balance. Without sufficient return capacity, your HVAC system may experience pressure imbalances that reduce efficiency and comfort.

You should inspect and clean your return air vents at least once annually, according to industry recommendations. However, homes with pets, allergy sufferers, or noticeable dust buildup may benefit from more frequent cleaning. 

Regular maintenance helps maintain good indoor air quality and ensures your HVAC system operates efficiently. Professional duct cleaning, which addresses the entire system beyond just the visible vents, is recommended every few years, depending on your home's specific conditions.
