"Dave From AAA responded promptly and provided top-notch professional service. He confirmed that the damage to my vent system was minimal, and even showed me how I could save several hundred dollars by completing the repair myself. Dave validated the trust I place in AAA Heating and AC."

"Everything from the information about the furnace and heat pump to installation was done in a professional manner. The installers were prompt and courteous. Before they left they explained how take care of the filters and the thermostat. It was not the cheapest bid but I have been dealing with this company for many years and felt comfortable going with them. I would recommend them to anyone who needs a new furnace or heat pump."

"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!"

"Rob came out to review our existing system and helped us figure out what kind and brand of heat pump would work best with our system. He was very patient and informative, and answered all our questions without any pressure or up-sells (we had quotes from five providers). We signed the contract and payed our deposit in June 2021, but unfortunately global supply chain issues delayed the parts being received. Day & Nite were communicative of the issue and offered several alternatives, including a refund of the deposit. We opted to wait for the parts. It took four months, but the techs (lead by Jeff B) were fantastic and very accommodating in how we wanted piping and wiring routed. We are very pleased with how it's turned out and loved working with a local (and family owned!) company! Our gas water heater is due for replacement soon, and we'll be coming back to Day & Nite for that!"

"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."

"From start, meeting with the sales technician (Matt) who was willing to meet with us twice, never tried to "sell" us on it, to installation (we are fortunate to live 5 minutes from the office) which took Andrew and crew one day, to finish total clean up and to the tutorial making sure we received a thorough explanation of the new system, this was a breeze of a process and all the seatown staff from the techs to the office support were very professional and helpful. Now we have a new furnace, heat pump and thermostat that will work together to keep our home comfy. Plus we got a filtration system that eliminates dust in the air and other pollutants making the air in air house more healthy to breathe. Our first experience with Seatown was service of our gas fireplace. It had gone out over the summer and I wasn't sure how to get it re-lit. I asked them to come to assess our situation to see if a heat pump would work in our house and even though they don't do gas fire places, they were willing to figure it out and it was lit."

"

      This firm is terrific !  First, they arrived on time to give us a bid and it was the most thorough evaluation of our heating needs that I have ever seen.  They gave us two choices and complete information for both.  We went with the more expensive unit w/ a better warranty and some additional energy saving features.  Additionally they compute the rebate from our power company and arrive w/ the documents so we did not have to go through the hassle of submitting it ourselves....note to competitors.....keep your bid simple and complete and take care of the rebate "details".  After signing the contract they arrived promptly at the agreed time and did a beautiful job of installation.  They were so careful of everything within the home...wearing shoe covers, vacuuming up after the job was completed and then carefully explaining how to operate the system.  This firm is, by far the most professional HVAC firm we have ever dealt with and I wish we'd used them for previous projects.   Ask for Al....he does an outstanding job and we couldn't be happier !

"My furnace broke down on a very cold day, causing my family to suffer. Dave arrived promptly on time after I contacted him and exhibited a high level of professionalism. Dave displayed impressive knowledge and skill throughout the repair process. My furnace problem was quickly diagnosed and Dave explained it to me in plain and understandable terms. I appreciated his transparency and honesty in discussing the necessary repairs and associated costs. I would recommend Dave's services to anyone who needs repair or upgrades to their HVAC system. Dave, thank you again for saving my family from a cold winter!"

"It went great! John, the original staff person, evaluated the furnace, explained what was needed and worked with me to select a good replacement. He did not pressure me to purchase a new furnace. A follow-up appointment for a second opinion validated that a new furnace would be best and within a few days (warm weather--not a problem) the furnace was installed with a better option for my electronic filter system. No muss, no fuss, as they say. I am delighted to have this new furnace."

FAQs for boiler or radiator heating system service projects in Seattle, WA

Radiator heat can be more expensive to install than forced-air systems due to the materials and technology involved. However, radiators often provide superior warmth and can improve indoor air quality by not circulating allergens. While the upfront costs may be higher, the enhanced energy efficiency and lasting performance can make radiators a worthwhile investment for a comfortable home.

If one radiator in your home isn't heating up, it might be due to trapped air or a blockage from debris or sludge. Your pro can bleed the radiator to release any air pockets. If that doesn't work, it might need a thorough cleaning or professional inspection. Regular maintenance helps prevent these issues and keeps your heating system running smoothly.

If your radiator is making banging, clanging, or hissing noises, it might have trapped air or loose parts. Your pro will likely start by bleeding the radiator to release any air pockets. Next, they’ll check that all valves, brackets, and pipes are securely tightened. Adding insulation can also help reduce noise. If the sounds persist and your pro recommends it, a replacement may be necessary.
