"From the estimate with Tyler, to install, through follow up support, SeaTown was exceptional. They were not the cheapest, but Tyler took the time to understand our needs and answer all of our questions. Way more knowledgeable and friendly then the other two quotes we got. Tyler made it an easy choice to go with SeaTown."

"We had such a great experience with Cascadia Comfort! Everyone was super friendly, helpful, and easy to work with. They showed up on time, explained everything, and made the whole process feel really easy. Our central AC is working perfectly, and we couldn’t be happier with the service. We would definitely recommend Cascadia Comfort to friends and family!"

"They were able to make things work for a very quick install and I really liked Teo and his son, Miguel who installed it. Very nice, responsive and did a good job. Price was competitive with all the other quotes and timing/service was excellent. Wouldn't hesitate to recommend them!"

"They contacted me with the right unit to buy and a reasonably priced supplier. They hadn’t installed my particular model before but were confident. I ordered the unit, paid up front, and told them when it arrived. They worked me into the schedule within the week and arrived first thing in the morning. The install had some quirks due to the unit not being straight forward to install in keeping with code, but the electrician explained how he was going to change the wiring to the unit in order to meet code and preserve the weather proofing. He was polite and friendly, gave me an extra warranty due to the unusual situation, and helped me pair my phone with the correct app for charging. He also quickly diagnosed and fixed my outlet. I was happy with everything and look forward to contacting them again when I need wiring."

"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."
