"Very professional personnel arrived on time and worked throughout the day. They explained each step and answered all our questions Bob was very knowledgeable An electrician was also on the site to complement the install and permits were pulled. Very smooth day"
"Crew was very prompt and professional. Took care to put booties on whenever entering the house and courteous of your needs. Very nice, professional installation and site picked up and cleaned after completion. Thorough walk through and explained any questions don’t hesrtate to call and they will be more than happy to come back out and help."
"I'd been wanting to get of our old electric baseboard heaters for a long time, and replace it with something more efficient, and Mark helped my understand the differences between a ductless mini-split system and a ducted heatpump system. Even in our small house, the ducted system was the way to go. Mark and his installers were professional and efficient, and answered all my questions. When the thermostat was acting a little odd, he sent a technician over to calibrate it, free of charge. There was a small issue where I initially got the wrong specs for the electrical, and as a result I had the electrician install unnecessary circuits, but Marc reimbursed me for the cost."
"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."
"Jose Ruiz was very professional explained every step of the process. As someone who knows nothing about plumbing he walked me through all the details. Thank you Jose for coming out to my home within 2 hours on a Friday evening. A job well done at a reasonable price. You Rock!!!"
"Blue Flame's team did a great job from the initial consultative assessment, bid and installation. Bid was competitive and fair. The entire team was service oriented and responsive. Installation was quick - two crews sent to enable one day install, complete and left clean and orderly. A+"
"This company made the process of getting a heat pump (new installation) very easy for us. They were fast on coming out for the initial bid (Brandon is great!) and they were super fast on the installation. Lorin and his crew were delightful and did an excellent job! There price for everything was way better than any other quote we received and they were very conscientious about how they made everything look. We are very satisfied with every aspect of this project and highly recommend them! I would definitely hire them again!"
"Daniel is a dedicated contractor who cares about his customer and the quality of his work. The insulation work went very well, but not every project goes smoothly. There was an issue with a crack to the ceiling drywall, which was corrected within 24 hours. The attic work dislodged some previously improperly installed wiring, and while the cause was not Daniel's, he took ownership of the situation and saw that the problems were corrected quickly and to my satisfaction. "
The right type of HVAC system will depend on several factors, including your climate, budget, preferences, and existing HVAC setup. For example, if you live in an area that experiences extreme weather, then a split system would likely be the best option. Or, if budget is a concern, consider installing a ductless system in just one room.
The cost-efficiency of baseboard heaters depends on the type and how you use them. Generally, standard electric baseboard heaters can be expensive to run because they use electric resistance heating, which is less energy-efficient than systems like forced-air or heat pumps. However, hydronic and gas versions are typically much cheaper to operate. Hydronic models are more energy-efficient because they heat a liquid that retains warmth longer, preventing the thermostat from turning on and off as often. The overall running cost is also influenced by local electricity rates, your home's insulation, and your usage habits. To increase efficiency, you can use baseboard heaters for zoning, meaning you only heat the specific rooms you are using.
A furnace takes in cool air, heats it through the burner and heat exchanger, and sends the air on its way to warm your home. A boiler is a pressurized vessel that produces hot water or steam to heat the home and provide hot water. A boiler may or may not work together with a furnace.
An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.
Costs depend on system size, efficiency rating, and additional features like zoning or smart controls.
