Best boiler installation pros near Seattle, WA

"We had an install from Greenwood in our new home and it is amazing! The staff was so kind and cleaned everything up, and the AC and heat works great. This is a company I would highly recommend!"

"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."

"Completely removed old heating system and installed new heat pump system in 2 days. Customer rep followed up with an installation verification and provided system details. All work was professional quality and technicians were very courteous and professional."

"Received 4 quotes. Cummings was the least expensive that I used to bargain two others to. They matched but had install dates of 30 days. Cummings had their electricians and HVAC guys here in 8 days. Installation done in 4 hours. All had good customer service & tech skills."

"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 three estimates at our house for our conversion from a gas forced-air furnace to a heat pump/gas furnace installation.  I was most impressed by Evergreen's rep. Scott, as he was very helpful in explaining the technology and was the only one of the three to do a J load calculation on our home.  I also felt after the estimates were all given that Evergreen's was the best buy in terms of the product features vs. overall cost.   As I researched our installation I realized that my mother's all-electric home would be better served by a heat pump as well.  Again, Scott did the best job of all three estimators there as well.  

After the down payment of 50% of the cost the installation was set up within two weeks for both locations.  The work was done on time and efficiently.  My mother's job was done in a few hours, mine took a couple of days.  I'm happy to say that both units are performing perfectly, through both the colder weather of March and the warmer than usual days we've had in April.  

There were a couple of things that should be mentioned, not major issues but worth noting.  

The installation of our heat/pump and furnace did not meet City Code on the initial inspection as the condensation pump was placed on the floor.   City code required it to be 18 inches off the floor due to a potential for an explosion should there be a gas leak.  The correction was done within a few days, but I did have to schedule a city inspector on two different days.   The city inspector remarked that the installer 'should have known better'.  

On my mom's split heat pump the indoor blower unit began making a loud clanking noise one month into use.  Evergreen was quick to come out, mom called on Sunday morning and was able to have a crew come out the next day.  Apparently the installers had missed a mounting clip on the external cover of the indoor unit and over time the casing sagged enough that the rotating fans began to hit the inside of the case.  

Several weeks after our work was done I was called by the financial office asking me to pay the remaining 50% balance.  I pointed out that it had been paid on the day the work was done, but apparently the payment was not correctly registered as having been paid by their accounting office.  Fortunately I was able to point to my credit card statement indicating that the balance had been paid in full.  

Overall Evergreen did a professional job from start to finish and I have no hesitation in recommending them.  Given their expertise and experience I have no doubt that my equipment will continue to be well serviced going forward.  "

"Jane's replaced my 20-year old Munchkin boiler with a super efficient, modern Rinnai. Everyone was a joy to deal with. Service was excellent. Darian, who scheduled and arranged the replacement, and Greg and Oscar (who did the work) were fantastic. Excellent service, especially since I live on Lopez Island, which is not easy to get to. Competent, good-natured, hard-working, nice folks."

"Miguel is my new plumber from now on- he was very patient in explaining what I needed to know about the job on hand. He was very polite and made sure I was comfortable with the choice I made. He also gave me proposals for a future project (possibly changing my water heater because itâ s 11 years old now , no issues-not leaking but I want to be proactive and to increase the property value as well). I will gladly recommend him to anybody who needs a new plumber. Heâ s just down right AWESOME!"

"I’m very pleased with the work they did. They were knowledgeable, professional, and responsive. I would definitely recommend them for all heating and cooling needs. They also service and install hot waters heaters, which we didn’t need, but I would recommend them for that as well."
