"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."

"From start to finish we were treated with respect and very courteous in covering their product and service. Arrived on time – introduced themselves – asked to see the layout. Asked if I had any questions and went right to work on the installation. The work went smoothly as each worker did his work. They never felt rushed as the work progressed and would keep their area cleaned along the way. When finished the work look very professionally done. I am very satisfied with their work."

Boiler Repair questions, answered by experts

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

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.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

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.

Addressing gaps and cracks reduces heat loss and improves energy use.
