"Dolly was on-time, professional and friendly! One of the things I love about AAA Heating and Cooling is that they send a text when they are on their way with a pic of the person that will be arriving. They put covers on their shoes when entering the home, and both our dogs could tell Dolly was a dog lover! She answered our questions and is very efficient. I recommend AAA Heating and Cooling to anyone in the area."

"Worked with Greenwood Heating and Air on a furnace replacement and only have excellent things to say about the company and team. Customer service, pricing, timeliness, thoroughness, and friendliness were top notch. Contacted them initially for an inspection of our 28-year old furnace. The technician Frej was prompt, thorough, and courteous, explaining in detail the issues we might face with this still working but old units. Based on the findings we reached out for a quote on a system replacement. Lori took diligent care in listening to our concerns and hopes for a new system, recommending systems that might work for our household. She was always available for follow-up questions, providing answers that really helped us decide on getting a new system (Trane XC80 furnace with air scrubber) via Greenwood H+A. Prices were fair, on par with expectations and quotes from other businesses. On the day of the install, the team at Greenwood H+A, including Jake, Jordan, and Jason were very flexible, coordinating with the roofing company we had hired to take down our chimney and replace with a vent, to get the project moving on time. They were all very communicative, which we appreciated, and gave us regular updates on the progress. They finished what seemed like a big job within the day, despite the install occurring in our cramped crawl space. Our house is now toasty warm again with a great new furnace and all the bells and whistles. Would definitely recommend them for similar job, including for custom requirements as was our case with the roof. Thanks!"

"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."

"Rob came out to review our existing system and helped us figure out what kind and brand of heat pump would work best with our system. He was very patient and informative, and answered all our questions without any pressure or up-sells (we had quotes from five providers). We signed the contract and payed our deposit in June 2021, but unfortunately global supply chain issues delayed the parts being received. Day & Nite were communicative of the issue and offered several alternatives, including a refund of the deposit. We opted to wait for the parts. It took four months, but the techs (lead by Jeff B) were fantastic and very accommodating in how we wanted piping and wiring routed. We are very pleased with how it's turned out and loved working with a local (and family owned!) company! Our gas water heater is due for replacement soon, and we'll be coming back to Day & Nite for that!"

"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."

"Cody was prompt with his quote and kept in contact with me constantly. Our project was able to start weeks ahead of schedule and was completed on time and on budget. Multiple crews worked on our home across a week and a half. Each individual was professional and was more than willing to spend time explaining each step of the process. They cleaned up each day leaving the house in almost better shape than when they started. They also worked with us around accommodating our animals. Cody was able to adjust and respond quickly to change requests we had during the project and we could not be happier with the result. Post install Cody has been great taking our calls for questions on the new system and helping us learn usage of the systems. He even walked me through an easy change to the tankless hot water heater spending a good hour on the phone with me. Overall Cody and the team at SeaTown electric heating and air have been wonderful to work with and have exceeded our expectations with our hvac and hot water tank replacement. We will be using them again for future projects."

"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."

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.
