"Everything from the information about the furnace and heat pump to installation was done in a professional manner. The installers were prompt and courteous. Before they left they explained how take care of the filters and the thermostat. It was not the cheapest bid but I have been dealing with this company for many years and felt comfortable going with them. I would recommend them to anyone who needs a new furnace or heat pump."

"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."

"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 won't call any other heating or AC experts ever again. Twice now, I've had incomparable experiences. I had another highly reputed company come diagnose my failed furnace and provide an estimate, but AirPros' price for the same part and repair was much more reasonable and furnace repairs are not cheap, so the difference mattered significantly. AirPros also treated me like family. Go with this family business, you will be happy."

"The installation did not go well at all. The installers were here all day and they tracked mud through our garage. They also did a sloppy job of installing the lines on the wall in the laundry room. The system didn't work so they called a technician to come check. The tech, Tobias, complained that we woke him up. He was very grumpy and we could hear him having angry conversations on his cell phone. He determined that the installers installed the air system upside down! The system worked backwards - heat came out through the intake vents and drew air from the heat vents! He complained to us that this had happened before. The installers returned a day or two later and were here all day fixing their mistakes. They joked with us that we should get an awesome service contract. Then the system required fine tuning and another tech (Chris, a very nice guy) was here multiple times tinkering with the system. When we called our sales rep, we were told he doesn't work there anymore. We requested to talk with the business owner, and were promised a phone call, which never came. On top of all that, the heat pump is SO LOUD and I wish our rep had explained to us how noisy it would be. At the end of the day, I sometimes wish I would have spent the additional few thousand dollars and hired Greenwood Heating and Air. Blue Flame had the best quote and the friendliest sales rep. But the installation was a sh!tshow and I cringe every time that heat pump turns on which I can hear from inside my house."

"Everything went well and smooth with their help. I got the proposal with all details at the same day when they came to do the estimate. Our old furnace was built on 1971, and it was in a closet next to the water heater tank. When one other company came to estimate, they wanted to cut a furnace size hole on the wall facing the hallway to fit the machine and we have to find a constructor or handy man to finish, like to build a door or make it look good, but G&S figured out an easy way, which is to turn the machine toward another direction and eventually only cut a vent on the wall. It took two days for all the installation, and they cleaned up when they left and everything looked clean and nice. They also listened to customers. We didn't want the heat pump to be right next to the stairs of our deck, so they chose a spot which was few feet away from the closest spot without any question. We appreciate for that, since the wind blows out from heat pump is kind of strong, and we feel comfortable with where it is at now. One thing I really like is they were on time, and they called around 30 minutes ahead before them showed up. They also take care all the paperwork for the PUD rebate, Costco 10% shop card, and city permits, and all we do is waiting their call to arrange the time."

"In June of this year I contracted with a large company to install a new heat pump at our residence.  While overall I felt they did a fairly decent job there were at least three instances of inconsistent service, attention to detail and disappointment.  The most disappointing aspect of that company's performance was when it came time to "test" my existing insulation and duct work.  I believed there bid to correct my existing ducts and insulation was outrageous.  That said, I was in between a rock and a hard place.  I had just installed a $12K heat pump and I feared any efficiencies I may have gained could be lost due to my existing ducts and insulation.
I contacted 5 companies to provide me with bids, in addition to the upsell price I was previously provided by the company I had install the heat pump.  All five companies are listed on Angie's List.  They all provided fairly consistent bids.  They all helped educate me on what I may need to resolve my existing duct and insulation issues.
Daniel was the final contractor I spoke with.  He showed up early afternoon, looking a bit haggard, as if he had just emerged from a crawlspace - he had.  I was somewhat tentative at first, but I knew I had found the right man for the job the minute he began outlying in detail everything he saw, what he would recommend, how he would address my specific issues and what it would cost.  He was upfront from the get go, wanting to work with my budget and my timetable.  
Daniel and his team showed up three days later and worked 12 hours on a Saturday in 85 degree heat, completely insulating the crawlspace of a 2,000 sf home.  He was back the next day to finish up, working another 7 hours, again in 85 degree heat.  He pointed out certain issues he found along the way, specifically some holes that needed patching with mesh and sealing all gaps in my flooring from the crawlspace.  He sealed all the ducts, adding screws where necessary.  He even sealed the holes drilled by the company who installed the heat pump (one example of their service inconsistency).
Daniel is an extremely hard worker.  I have the utmost respect for his abilities and would recommend him to anyone looking to have any type of crawlspace / insulation work done.  Sure, shop around, talk to the various companies on Angies List, get educated and then do what I did, call Daniel last, negotiate a price and get the job done right.

FAQs for boiler or radiator heating system service projects in Seattle, WA

The way an outdoor wood furnace works is that it burns wood inside a firebox to generate heat. This heat is transferred to the air around it, which is then distributed throughout your home using a dedicated system. If the furnace is properly sized, you can also integrate it with your hot water supply for efficient heating.

Standard outdoor wood furnaces are 75% efficient on average, meaning that they convert 75% of the wood's energy into heat and waste the rest as smoke. Gasification wood furnaces are over 90% efficient because they burn the wood and the smoke particles, using less wood to produce the same amount of heat as standard models.

With proper care, an outdoor wood furnace can last between 15 and 20 years. Regular weekly cleaning, annual professional inspections, and prompt repairs can extend its lifespan up to 30 years. Proactively addressing issues early can prevent costly repairs and premature replacement. Consistent maintenance ensures efficient heating and protects your investment over the long term.

You should install your outdoor wood furnace between 30 and 500 feet from your house to meet safety and regulatory standards. This distance minimizes fire risks and ensures you comply with local building codes and insurance requirements. The ideal placement of an outdoor wood furnace or boiler balances convenience with safety, allowing for efficient heat transfer while reducing smoke exposure. Also consider wind patterns, property boundaries, and accessibility for wood delivery when choosing the optimal location for your installation.
