"When Airpros installed our central air a few years ago, I got a quote for a tankless water heater. We waffled on it for a long while, but our old one was getting kind of flaky. When I got back in touch, Mark honored the existing quote despite a slight price increase in the water heater. They came on the day stated, installed the new water heater, and removed the old. They left no mess and were done when they said they'd be. This is exactly how all home improvement jobs ought to go!"

"Very well. The technician was knowledgeable and willing to explain what he did and found. He left a good report on his findings. He also cleaned the electronic air filter, which I wasn't expecting. The price I paid was an Angie's List special $39 - great price and service!"

"Worked with Greenwood Heating and Air on a furnace replacement and only have excellent things to say about the company and team. Customer service, pricing, timeliness, thoroughness, and friendliness were top notch. Contacted them initially for an inspection of our 28-year old furnace. The technician Frej was prompt, thorough, and courteous, explaining in detail the issues we might face with this still working but old units. Based on the findings we reached out for a quote on a system replacement. Lori took diligent care in listening to our concerns and hopes for a new system, recommending systems that might work for our household. She was always available for follow-up questions, providing answers that really helped us decide on getting a new system (Trane XC80 furnace with air scrubber) via Greenwood H+A. Prices were fair, on par with expectations and quotes from other businesses. On the day of the install, the team at Greenwood H+A, including Jake, Jordan, and Jason were very flexible, coordinating with the roofing company we had hired to take down our chimney and replace with a vent, to get the project moving on time. They were all very communicative, which we appreciated, and gave us regular updates on the progress. They finished what seemed like a big job within the day, despite the install occurring in our cramped crawl space. Our house is now toasty warm again with a great new furnace and all the bells and whistles. Would definitely recommend them for similar job, including for custom requirements as was our case with the roof. Thanks!"

"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."

"I give SeaTown Electric Heating and Air my highest recommendation. Our technician David, arrived on time and was super helpful. This company doesn't try to sell you something you don't need, but are fully focused on the problem and customer service. I learned a lot from David about the American Standard System we have, so I can better properly spot problems to take care of, and when to call for service. SeaTown is now a go-to company for our home, rentals, and recommendations to family and friends."

"Evergreen installed a new hybrid heat pump system in my house. After researching the options, Evergreen was not only the most reasonable price, but they also scoped out a hybrid system where they would install new duct work and a single air exchanger in the attic and a minisplit in the basement. Scott, the sales person, did not try to upsell me on number of zones (others tried to get me to get 2 units in the basement) and after 2 months with the system, the single unit in the basement is heating the whole basement to our needs. All this was done at a price still considerably lower than the "standard" system price being offered by one of the bigger, similarly named companies. Evergreen was also the only company to propose a hybrid system where they would install a single exchanger in the attic and run new ceiling ducts to the rooms. This was appealing because we don't need to have the cassettes in each room and we didn't need to line the outside of the house with conduit for the cassettes (also the bathroom gets heat, too). Scott was great to work with, answered all my questions, and did his best to size the system correctly. Installation was smooth. There was a small hiccup where the installer accidentally broke a basement window, but Evergreen squared it away. Don and his team were great and the inspections passed. After install support has been great. Denise has been responsive to my questions. Overall, the experience was great with Evergreen and I highly recommend them."

FAQs for air conditioning projects in Mercer Island, WA

Most professional HVAC technicians require two to three hours to complete an expansion valve replacement. The timeframe depends on your unit's accessibility and whether additional repairs are needed. The process involves recovering refrigerant, removing the old valve, installing the new component, and recharging the system. Scheduling during less busy seasons may result in more convenient appointment times.

Operating your air conditioner with a malfunctioning expansion valve isn't advisable. Continuing to run the system could potentially damage other components, particularly your compressor, which is significantly more expensive to replace. If you notice performance issues like inconsistent cooling or unusual noises, it's best to have your system inspected before continuing regular use.

Expansion valves don't have a standard replacement schedule, as their longevity depends on system usage, maintenance frequency, and environmental factors. Regular professional maintenance helps identify potential valve issues before they cause system failure. Having your HVAC system serviced annually allows technicians to monitor component condition and recommend preventative replacements when necessary.

Refrigerant leaks require prompt professional attention. If your expansion valve is leaking, you'll likely notice reduced cooling performance and possibly hear hissing sounds near the unit. Addressing leaks quickly prevents further system inefficiency and avoids the environmental impact of released refrigerant. Your HVAC technician will need to repair the leak and recharge the system with the proper refrigerant type and amount.

Because many AC issues present similar symptoms, professional diagnosis is recommended. Problems like inadequate cooling, inconsistent temperatures, or strange noises could indicate expansion valve issues, but might also stem from refrigerant leaks, electrical problems, or airflow restrictions. A qualified HVAC technician has the tools and expertise to accurately identify the root cause and recommend appropriate repairs.
