Every year it seems like our HVAC + Tankless Water Heater service goes up in cost. And the techs we…read morehave previously used often arrive and do just and adequate job. This time I shopped around and found a good rate from Skyline. Checked their business license, insurance, and LNI and they looked clean. So I gave them a shot. Scott came and spent about 2 hours working on our heat pump, furnace, and descaling our tankless water heater. He was very organized and had the right equipment for the jobs in his truck. Good sense of humor, but also good advice around how to best upkeep those systems in my house. I ended up getting a discount by purchasing this year's service and next year's together. Very happy with Skyline's work and look forward to using them for years to come.

An easy 5/5 rating, really appreciate Scott and his team. Communication was clear and prompt, they…read morewere very punctual for both appointments, and the pricing was fair and easy to understand. I had them come out and re-route my furnace's exhaust pipes, specifically fixing the terrible job a previous HVAC company did, and Scott fixed it in a fraction of the time with none of the hassle or mess. He even went above and beyond and replaced our air filter for us and repaired the vinyl tubing for pumping out furnace condensate, too.

They were able to make it out within a day or two both times. The owner was easy to work with for scheduling. They don't try to pressure you or upsell at all, which I appreciated. The quotes I got were in line with other area vendors. The technicians were very professional and helpful despite the resident of the house being very crotchety. Would definitely hire this company again.

Instead of pushing for a service visit, he spent about 20 minutes on the phone patiently walking me through a few diagnostic steps because he suspected it might be a common issue based on my description. We were able to identify the problem together, which I'm very grateful for. That kind of honesty and willingness to help is rare and says a lot about someone's character. I really appreciate the time he took to help me out and would definitely recommend him and his company to others.

I also appreciated that he didn't try to upsell me on anything I didn't need - I asked about installing a heat pump and he explained why it didn't make financial sense in my situation. Twice since then I've gotten in over my head with DIY HVAC projects. Both times I've called James to ask for help and he's been able to walk me through how to fix the issue myself without requiring a service call. It's a huge relief to have an expert you can trust. I'd highly recommend calling James for any HVAC needs.

Holden Village recently had the pleasure of working with James Colver of Allied Heating and AC…read moreSolutions, an outstanding HVAC contractor who exceeded our expectations in every aspect of a major water heating system upgrade. Beginning with the initial consultation, he took time to carefully assess the condition and limitations of the aging electric water heaters in our hotel/dining hall. Rather than offer a quick fix, he conducted a thorough analysis of our facility's needs, listening closely to feedback from multiple stakeholders before proposing a long-term solution. Holden Village presents unique challenges for a contractor. We are an ecumenical retreat center built in an abandoned mining town high in the North Cascades Mountains. The only access to the Village is by ferry boat up Lake Chelan and then by Holden's bus transport ten miles up a steep gravel road. We produce our own power with a hydroelectric system, operate our own water treatment system and septic system, and repair and maintain our 1930s lodges, chalets, and community spaces. Everything we need must be transported in by barge, ferry, and truck. James's recommendation--a high-efficiency heat pump water heating system--was not only environmentally forward-thinking but is projected to reduce our energy costs by up to 90% in our hotel. This substantially reduces the load on our hydroelectric system and perfectly aligns with our long-term goal of becoming a carbon neutral facility. James walked us through every detail of the system's performance, benefits, and installation process with clarity and professionalism, making sure we understood what to expect. Once we agreed on the scope of the project, James took all these challenges in stride, arranging to bring his own vehicle in by barge, fully stocked with the tools and equipment he needed to complete the job. The installation itself was seamless. Despite the complexity of our custom-built energy management system, he integrated the new heat pump with impressive technical skill, ensuring compatibility and peak performance. Throughout the process, he was consistently courteous, respectful of our operational needs, and kept disruptions to an absolute minimum. James and Allied Heating and AC Solutions didn't just provide a product; they took the time to understand our situation and learn what was important to us, and then delivered a thoughtful, cost-saving, and expertly executed solution. James's ability to blend technical expertise with excellent communication and stakeholder engagement made the entire experience positive and stress-free. We wholeheartedly recommend him to anyone seeking a trusted HVAC professional who goes above and beyond.

Top marks all around. We needed to place our aged furnace…read moreand A/C units and called Better Air NW to come out for an estimate. Colin took the time to learn our wants and needs, understand our current system, and most importantly, what we did not want. It was a frank discussion to match the install with what we wanted; no upselling, no pushing for a heat pump once we said we didn't want one, no pushing extra services. Straightforward and honest. The estimate was right in the middle of the range (for this area), and we were able to schedule the work for early the next week. It was going to be a single day, but our "mission glitch" was some less-than-up-to-code electrical on the old system that needed to be brought up to code. That added a few hours and ran us over into the next day, but it was done at no extra charge. From start to finish, communication was timely and clear, by text and phone with email as a backup. Scheduling was a breeze and teams arrived exactly when they promised. The quality of work is excellent, and it all comes with a ten year warranty. Pleasant, professional, efficient.

They sent someone over, who didn't really open the HVAC system panel much. I didn't seem confident that this would fix it. But they recommended to fix the drain pan inside the evaporator coil box, which they said was much more expensive. For clearing the drain pipe and gluing a loose pipe, which didn't actually fix the main problem, they still billed me $300 - diagnostic fee ($99) + 1 hour ($199) - (there's a 3% credit card fee, but they accept checks) 4 or 5 hours later, there was dripping again. I ended up calling Bob's, they sent 2 technicians who knew what they were doing (they opened the panel properly), they found and fixed the issue - it did not involve replacing a drain pan. Bob's only charged me the diagnostic fee of $175 and did the job right (compared to $300 that Green Bear charged)

Excellent service from Boris S. and his colleague…read more My gas water heater had stopped working, and I also had a toilet with a slow leak. They arrived on time, sent an ETA text beforehand, quickly diagnosed the issues, and had the water heater running again within about 20-25 minutes. Boris also took the time to discuss replacement options for the future, including a Bradford White water heater, and promised to follow up with a quote and recommendations. The toilet repair will need a little more time to confirm, but overall I was very pleased with their professionalism, communication, and responsiveness.

Andres was very responsive to my questions and were open to handling the permit, which is often a challenge with other contractors. Adrian showed up promptly for install, arriving on time and got right to work. He was very thorough and the install looked great when he got done. You can tell he takes pride in his work. The issue I had with Greentop is the warranty registration, which was incorrectly registered with my name and contact info as the dealer. I traded a couple e-mails with Vera and was then ghosted. I ended up calling the manuf myself to have them at least correct the name of the dealer on my warranty registration to Greentop. They advised they couldn't change the contact info. I'm hoping I don't have any warranty issues down the line due to their error.

As of April 13th, I am still being double charged and the issue has not been resolved. I have been flexible and willing to work with them, but the owner Mark and the sales guy Loren made that impossible. Loren will say anything to close a deal. The lack of oversight is staggering. They refused to do a walkthrough with the installer and seller, which led to two heat pumps being installed incorrectly. They had to be moved, and that caused even more damage to my home. They also charged my credit card while "charging" a Synchrony loan, so I have been effectively double-charged for months. Now they refuse to speak on the phone and only send haphazard email replies that never resolve anything. They promised to fix the drywall in writing. This was necessary to repair their own mistakes and because I preferred to have the electrical work go through the house, which they agreed to. Instead, they sent a third-party worker and then demanded a massive payment for the repair. They eventually gave me a payment to cover the drywall fixes myself, which I am grateful for, but even that took over 3 months of fighting. The actual installers and electricians were amazing. They should go find a new job at another installer with actual integrity. My problem is entirely with Mark and Loren. Since they use AI for their reviews, expect a fake reply from Max below.
