Get matched with top boiler installation pros in Duvall, WA

"Of the eight companies who bid, Greenwood did the best assessment of the somewhat quirky situation my old house presented. The estimator came just a few days before the big freeze in January, and they were able to schedule installation within two days. Once the installers were on site, there was some confusion re where various components would go, but a phone call to the company cleared that up within an hour. From then on the heat pump installation went smoothly and professionally, the electricians did a quick and effective job of hooking it up to the service, and the site was left clean. I did not understand at first how to operate the thermostat, given that the Mitsubishi owners manual was of limited help, and per my request a rep from the company came out a few days later to give me a tutorial about what the range of settings can do. From then on the system has operated flawlessly and lives up to its reputation."

"Ken went above and beyond on making sure that our install went flawlessly. He navigated through PSE issuers that could have become serious with our gas being shot off from PSE. Best customer service feasible!!!!"

"When Airpros installed our central air a few years ago, I got a quote for a tankless water heater. We waffled on it for a long while, but our old one was getting kind of flaky. When I got back in touch, Mark honored the existing quote despite a slight price increase in the water heater. They came on the day stated, installed the new water heater, and removed the old. They left no mess and were done when they said they'd be. This is exactly how all home improvement jobs ought to go!"

"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."

"From the friendly phone call scheduling the service to the urgently needed installation of a new hot water heater, the customer service was excellent. All steps were explained and our questions were answered. Well done!"

"Darrick came out when no one else could and went through my Furnace and Air conditioner. The furnace was fine but found a potential problem with the air conditioner and went out of his way to get the part and fix it right away. I am now looking at having them install a new Thermostat for me. I Highly recommend them and would use them for all my needs."

"It went great, the heat pump and furnace have worked well, they installed a Bryant system that has done great over the past few years, house is cool in summer and warm in winter, I have no complaints."

"I had my furnace repaired & a new water heater installed. Father & son were professional, friendly & performed all the work with technical expertise. Explained & showed my everything. I received a fair price for all the work done. I would highly recommend this wonderful team for any HVAC work you need done. I'm very pleased."

"Starting with the sales process, Nate was informative and great. Could've sold me a more expensive replacement system, but instead identifies how my current system cod be retrofitted with a heat pump. That sold me on G&S right there. Everything from the initial install review, the office staff working with my lender, to Izaak and the install and electrical teams, was punctual, informative and professional. I've had several bad experiences with other contractors, but I would confidently recommend G&S for any job and plan to use them again for a generator switch install. Good people with a good business. Thank you G&S!"

"We'd used them four years ago to replace our windows. They were about 40% the cost of Renewal By Andersen for the same Andersen windows, were professional and courteous throughout the process, and we haven't had a single problem since. So when we wanted to put in a heat pump system for efficient heating and cooling they were high on our list. We got four bids, and once again they were the least expensive, in this case by a 30% margin. They explained our options well, came up with some creative solutions (we're an old house with old vent-work which they bypassed for the ductless pumps but used for a top quality air filter), and did the job quickly and efficiently. They've checked back a couple of times since to make sure everything is ok, which it is, and it's been really nice to heat our bedroom on some cold nights and cool my western facing home office on some sunny afternoons). When the permit inspector asked before they came over who our installer is and I told them, they said "They do really good work." Definitely recommend them to others and in fact already have."
