"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."

"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

When it comes to bleeding a radiator, the goal is to let out trapped air rather than letting out the water. Naturally, some water will dribble out when you open the valve to let out the air. But you don’t want a lot of water to leak out. Just leave the valve open long enough that the hissing noise stops, meaning the air has escaped, and just a dribble of water comes out of the radiator.

There are several types of home radiators, and the most common are steam heat radiators, electric radiators, and dual-fuel radiators. Steam heat radiators are connected to a boiler. Electric radiators can operate without being connected to anything else—they just need an electrical outlet. If you have a dual-fuel radiator, you’ll see a valve at the bottom of the system with a wire coming out of it and going into a wall. These are often your towel radiators in the bathroom. The type of radiator you have will impact how you turn it on.

Regular inspections, filter replacements, and professional tune-ups keep the system running efficiently.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.
