Green Mountain 40Green Mountain Stoves by HearthStone Share Manufacturer: Hearthstone Quality Home Heating Products Inc Brand: HearthStone Collection: Green Mountain Stoves Model: Green Mountain 40 Year: 2022 Add to Quote Check Availability Ask a Question Trade-In Value Apply for Financing These "new kids on the block" are amazing. Their communications are EXCELLENT and their service as well. I had a poorly installed cap from installer recommended by a long standing competitor and will no longer use their competition! Highly recommend using Armstrongs. Timely, communicative, fairly priced! Kim Mikkelsen I shopped around to replace an old, uncertified wood stove. Armstrong's was the only shop that recommended Jake come out to do a site assessment to better help me decide on the best stove for my usage. Jake gave me a detailed, printed estimate. He was honest in his responses to my questions even when those responses were not in his favor. Jake runs the business with integrity that puts the customer at ease. I will return to Armstrong's for any future purchases. Nancy MacDonald It’s been a long time coming but I would greatly like to say thank you to Armstrong’s Stove and Spa. They did everything in the power to help with our pellet stove. They offered us every option they could to ensure our needs were met and in the end fixed our issue. Kudos to the hard working staff, so very polite, and generous. You have a customer who appreciates what you do. Thank you. Timothy Schaff Amazing people to work with! Very knowledgeable when it comes to hot tubs! Super friendly as well! Would highly recommend to others! (Which We already have.) Can’t wait to discuss fireplace options with them in the fall! Danielle Tobia Armstrong’s Of Yakima is amazing! They are very knowledgeable, friendly and very responsive with any questions I may have. We just had our new Bullfrog spa delivered. The delivery was perfect, the spa is beautiful. We are first time spa owners with a lot of questions. They went above and beyond to explain everything and answer all of my questions. I feel like we are in great hands! Thank you to the owners, and staff. I would definitely recommend them! Kaylyn Cooley The staff at Armstrong’s are always knowledgeable and attentive. We are very pleased with the fireplace inserts we’ve purchased, and they make time for us when we need maintenance or an issue resolved. Excellent, local company!
