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.

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.

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.

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.

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)

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.

I really appreciate the time he took to help me out and would definitely recommend him and his company to others.

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. Save your sanity and hire a company that won't hold your money hostage.

Everyone has been really great to work with. May 2024 - I finally scheduled our annual maintenance. They sent James out. He was fantastic. A wealth of knowledge, polite and professional. I signed up for the annual maintenance plan to save money. He made good recommendations based on my needs and concerns of my allergies. Much appreciated! 2026 update - our heat pump stopped working and needed replacement parts. I paid for them to send a tech to diagnose it and they followed through with the work which is under the 10-year warranty. Tech, Hagen was very nice and professional and made sure to answer all of my questions. Kudos to the office staff, Brittny, Erin and everyone who took my calls while I was eagerly waiting for parts & repair. They treated me very kindly and proactively communicated each step of the way. I hope that this fix lasts a long time, or at least until we upgrade to a newer, more environmentally friendly unit.

We've used CM for heat pump installations in two houses. Most recently, we purchased a heat pump in…read more2019. When it stopped heating in Winter (thankfully, we have back-up propane), CM quoted us $3,200 for a thermal expansion valve (TXV) replacement. They explicitly said that while the parts were covered under warranty, the labor was not. We got a second opinion -- and while the part failed, the second company pointed out that we had a 10 year parts and labor warranty (he was easily able to get to this info, which means CM should have, too -- especially since they sold it to me). I've now called CM several times to inform them that they need to cover the repair, but I've been ghosted. I assume this is likely because they can charge a higher rate for labor on a customer-pay job than they can be paid by the warranty company and are hoping I'll go to another company, but I have no proof of that. As far as I'm concerned, they sold me the unit and the warranty -- and they can do the repair. Once the warranty is over? I'll never deal with CM again.
