"Professional and courteous. They're not going to do you any favors but their service is solid. They fixed a leak on my Mitsubishi Mr. Slim ductless mini-split (a heater/ac wall unit). First, one of their techs came out to diagnose. He checked some stuff, found that there was no refrigerant and scheduled an LSR tech (leak, search and repair). Diagnosis: $215 The LSR tech came out, checked the system and found that there was a loose valve. He tightened it and checked the system and we were good to go. He evacuated the system and charged it with refrigerant. He also did maintenance on the outside unit. It looked pretty clean after he was done. Nitrogen Leak Check System (bubble test for leaks): $651 Repair Each Leak and test: $193 per fix Evacuate System: $432 Charge System with Refrigerant: $491 Subtotal: $1982 Yup, two thousand dollars. This is Seattle for you and not sunny Los Angeles. They probably could have taken off the fix charge but I get it. Either way, they fixed my system and I'm happy. I would recommend Greenwood based on their solid service and professionalism. If you're getting an AC unit fixed get quotes! I submitted requests for quotes after the diagnosis and out of the 5 or 6 companies that I contacted nobody would give me a quote and they wanted to send out their own tech to diagnose. But I already had a diagnosis. So I just went with Greenwood. I hope this helps someone out there. My AC is ice cold and I'm happy. Maybe it'll spit out popsicles!"

"I won't call any other heating or AC experts ever again. Twice now, I've had incomparable experiences. I had another highly reputed company come diagnose my failed furnace and provide an estimate, but AirPros' price for the same part and repair was much more reasonable and furnace repairs are not cheap, so the difference mattered significantly. AirPros also treated me like family. Go with this family business, you will be happy."

"Jane's replaced my 20-year old Munchkin boiler with a super efficient, modern Rinnai. Everyone was a joy to deal with. Service was excellent. Darian, who scheduled and arranged the replacement, and Greg and Oscar (who did the work) were fantastic. Excellent service, especially since I live on Lopez Island, which is not easy to get to. Competent, good-natured, hard-working, nice folks."

"Darrick came out when no one else could and went through my Furnace and Air conditioner. The furnace was fine but found a potential problem with the air conditioner and went out of his way to get the part and fix it right away. I am now looking at having them install a new Thermostat for me. I Highly recommend them and would use them for all my needs."

"John provided great service and got the job done! For sure, I would hire again. However, I rated a B because the total cost was not 1) what I was quoted and 2) was given to me after the service was done. This would not have changed the outcome (I would have said yes do it) but customers should be informed of what the cost will be before anything is fixed."

"G&S was my second ductless system bid. My townhouse neighbors use the roll around portable A/C units to cool isolated sections of their homes but I wanted a system that did it all. Initial consult with Jesse was thorough and professional. Follow up scheduling, payment planning and customer care by Dawn was equally professional and accommodating. Workers got here promptly on appointed day. Immediately assessed the workload and called backup. They got it all done between 8:30 and 4:30 which even amazed them. I had one refrigerant leak after 3 weeks. Technician was out here during 4-hour scheduled window and repaired leak. All is well and I'm freezing happily ever after.

Boiler Repair questions, answered by experts

Pipes in your house can freeze after six hours or so if you lose power and temperatures are below freezing. You can prepare for potential power outages by winterizing your pipes with insulation. Also, whenever temperatures drop below 20 degrees Fahrenheit, turn your faucets on very low and leave them dripping until temperatures rise.

Radiators are a popular home heating choice in older homes, but they are becoming less common in new-construction homes. According to a 2022 report by Elements Visual Capitalist, only around 1.3% of new single-family homes have radiators and similar heating systems, such as baseboard heating.

While they may not be as popular as they once were, radiators today come with more energy-efficient features that can make them practical for modern homeowners.

If you have multiple radiators, start by bleeding a first-floor radiator that is farthest from the boiler. Work your way toward the boiler on the first floor before moving to the next floor, where you’ll again start by bleeding the radiator farthest from the boiler. Continue this pattern for radiators on each floor until they’ve all been bled.

Signs of needing a new expansion tank include visible leaks and a dull sound when you knock your knuckles against the tank (working tanks should sound hollow). A malfunctioning tank may also sweat with condensation, cause pipes to create loud noises when the system is turned off, and lead to very high-pressure readings on the boiler’s gauges. When in doubt, call for a professional inspection to find the source of the problem.

After you receive your audit and report, review the findings and determine which of the prescribed changes you want to make to improve your home’s energy efficiency. Start by contacting the type of professionals recommended by the auditor who can help you remedy the issues discovered during the audit. Prioritize the projects by urgency, importance, and budget. Then, gather estimates from several professionals, remembering to verify any necessary licensing and experience information.
