"Ranger did a great job. The estimators were friendly and thorough, the installers and team we encountered were all respectful and hard working. There was a problem with the electronics in the thermostat from the factory, they worked late and had to bring a new thermostat the next day, but the new one works perfectly. We will hire again for any other HVAC needs. We chose a higher quality AC unit and are glad we went with a quieter model, the unit is so quiet in the backyard."

"Daniel and his crew at SOS are everything you want in a service provider: affordable, thorough, friendly, experienced, and efficient! We got four bids for a full clean-out of our crawlspace. Three of the four estimators gave us a similar assessment (the fourth missed some big issues). Daniel did a thorough inspection, clearly explained what needed to be done, answered all of our questions, and provided us with a bid that was significantly less than his competitors (and it's no wonder - the larger providers have nice company cars, glossy folders, and fancy CD's).
We scheduled the clean-out for a few days later (the larger companies were scheduling 1 1/2 to 2 weeks out). Daniel's team arrived on time, worked quickly and efficiently, and did an excellent job. Because there was one small area under some steps that was difficult to access, Daniel returned a few days later to complete the job. However, he wouldn't take any payment until he was sure that we were completely satisfied with the work! It was clear to us that customer satisfaction is a top priority for SOS.
If you want the job done right for a fair price, we highly recommend SOS!

"Excellent service from start to finish. John, Isaak and Nate have always provided great solutions at a fair price. They were able to accommodate our quick time frame and made sure every detail was in order and explained fully at final trim! We are happy to call them “our” HVAC guys! Would recommend them highly to anyone!"

"This review is long overdue in my praise of Washington Energy Services for their customer service, pricing and workmanship ! My first interaction was in 1999 when they installed windows throughout my house. They are still in excellent condition. I might note I called them over 20 years later to inquire on how I could repair a broken slider and they sent someone right out, charging a very nominal amount to repair it. In 2020, I needed to replace my hot water tank, and the extremely knowledgeable Christy presented several options, answering my many questions. I settled on one with a booster that seemed to best fit my needs. Finally, in December 2023, I purchased a new gas furnace from WES. I had a minor issue with a fan switch and they responded quickly to rectify the situation. Within the past two months, I seemed to be having an issue with my thermostat (something they had not installed), and the manager, Greg, came out twice with his crew to explore the problem. Today they installed a new thermostat FREE OF CHARGE! Their excellent response and customer service is beyond any company I have hired. And I particularly love that they are family owned and have been around for decades. Their employees seem to be there for the long haul, which speaks highly of the owner. I refer all my friends and family and I won't go anywhere else for services that they offer. Many thanks to the staff I have interacted with over the past 25 years!"

"They installed the product faster than expected and were very professional. I noticed after they left that my backyard was actually CLEANER. They took the time to actually pick up some empty water bottles and trash that a previous work crew had carelessly left in the yard. When they had to move items in my garage they were carefully moved and actually organized better on the opposite wall. I asked that they leave them there. The unit is working great and I am amazed at the gallons of humidity it has removed from my home. I compare this to another big name company that I used to install air conditioning in my previous home. I went with the price and the big name. But I have learned that in central air it is really the installation that matters. My previous unit failed inspection and they had to come out and fix problems. When the fan came on there was a big 'bang' from the plenum over the furnace bulging out. They had not allowed a large enough air opening to get to the furnace so there was a whistling sound. Sure, it cooled the house but you really knew when it came on. I highly recommend Mercurio's for their installation work especially."

"I got an excellent service from this company. I called them for a simple AC maintenance check and they were very thorough. The technician checked everything from the AC unit all the way to the furnace and he was so reassuring. I must say, it was quite nice dealing with them on the phone and in person. I will continue using their service."

"Great service and work. Simon was professional, friendly, and informational. He showed me the before and after pics of my vent. He also gave me great tips on filters and vent covers. I was initially a little confused on how a $69 promo deal to clean all vents ended up to be a lot more, but Simon left the workorder out so that I could understand how the estimate was calculated (just verbally discussing wasn’t making sense at first.) I also don’t know much about vents so I didn’t know what questions to ask or what was part of the $69 promo. I feel Simon has educated me enough so that I know more of what to expect on my next cleaning."

FAQs for window a/c unit service or relocation projects in Vashon, WA

If your window air conditioner is relatively new or of high quality, repairing it can restore optimal performance and protect your investment. However, for older units or those with ongoing issues, it might be more cost-effective to replace the unit to ensure long-term efficiency and reliability. Consider the unit's age, the severity of the problem, repair costs versus replacement, and energy efficiency ratings when making your decision. If repairs cost more than half the price of a new unit, replacement is typically the better option.

Window air conditioners last eight to ten years on average. After this time, you may notice decreased efficiency and component wear. Replacing an older unit can improve energy savings and provide updated features like remote controls and better overall performance. With proper maintenance including regular filter cleaning, coil checks, and professional servicing, you can maximize your unit's lifespan.

If your portable AC isn't cooling, it might have a refrigerant leak or a circuit malfunction that's preventing it from working properly. It's best to contact a local air conditioner contractor to inspect and repair the unit. If your AC is older and repairs don't fix the issue, replacing it might be the most effective solution.

Removing a wall-mounted AC costs $55 to $75. Completing the removal yourself at the end of each summer season, being sure to do so according to proper guidelines, keeps you within this cost range. Should you require professional assistance for removal and disposal, if you can't move the unit yourself, expect an added fee of $25 to $50 to the overall cost.
