"Evergreen installed a new hybrid heat pump system in my house. After researching the options, Evergreen was not only the most reasonable price, but they also scoped out a hybrid system where they would install new duct work and a single air exchanger in the attic and a minisplit in the basement. Scott, the sales person, did not try to upsell me on number of zones (others tried to get me to get 2 units in the basement) and after 2 months with the system, the single unit in the basement is heating the whole basement to our needs. All this was done at a price still considerably lower than the "standard" system price being offered by one of the bigger, similarly named companies. Evergreen was also the only company to propose a hybrid system where they would install a single exchanger in the attic and run new ceiling ducts to the rooms. This was appealing because we don't need to have the cassettes in each room and we didn't need to line the outside of the house with conduit for the cassettes (also the bathroom gets heat, too). Scott was great to work with, answered all my questions, and did his best to size the system correctly. Installation was smooth. There was a small hiccup where the installer accidentally broke a basement window, but Evergreen squared it away. Don and his team were great and the inspections passed. After install support has been great. Denise has been responsive to my questions. Overall, the experience was great with Evergreen and I highly recommend them."

"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."

"Not smoothly. We selected Blue Flame because they were cheaper than Greenwood Heating & Air, and they could do the work immediately, while Greenwood had a waitlist several weeks long (should have been a clue). If I had to summarize the experience I would say communication was poor, requiring me to project manage the replacement more than I wanted to. Half the time you tried to call the office, they wouldn't pick up and you were passed onto an answering service who would ask you a list of generic questions like "Where did you hear about Blue Flame" and "Are you interested in purchasing a system?"... I've already purchased a system that I'm trying to finish having installed!!! The actual instillation took longer than they predicted, and while I appreciated the workers staying late into the night to work on the project, they didn't come prepared with all the equipment to do the work. They needed to borrow my extension cord because they didn't have one, and ended up plugging into the outlet in our backyard without asking, leaving our yard gate wide open. Fortunately our dog didn't escape before the open gate was noticed several hours later. They also helped themselves to items from our garage without asking, like our broom to sweep up their trash and debris. Lastly, and possibly most serious, the workers who were installing the system in our house were constantly pulling down their Covid masks when they thought we weren't around, and would scramble to pull them back up when they saw us. Bottom line, I probably got a good price on the unit and work, but it's not a very polished or professional company, so fingers crossed that everything was installed properly and will work for years to come."

"I have worked with Cardinal on maintenance for my heat pump and have been very happy with their service. Called them for a quote on this project, along with several other suppliers and their price was competitive. Also, they were the most responsive, able to turn my request around and send a tech out the next day, even though we were in a bit of a cold snap that had them quite busy. I have a B on punctuality only because the job took longer than expected but frankly, the fact that they were able to fit me in so quickly(before a leak could turn into a mess!) was a high point of the experience. The tech was knowledgeable and friendly, answering any questions that I had and flexible in meeting my requests with regards to adjustments, etc. The next week when I wanted the water setting hotter, they sent someone out the same day I called, as a follow-up to adjust the temperature. I have been quite happy with the experience and would highly recommend them. I also wanted to note that they have a good reputation around this area...one of the plumbers that I called actually recommended them over himself for the particular setup that I needed."
