"Allred is THE best. I had mini-split AC/heat installed almost a year ago. I love it and it's saving me significant money over using my central heating system. And no more hassle with portable air conditioners. I should have done this years ago. Even better is the 5 star customer service. Last week I had difficulty turning on the AC for the first time since last summer. I urgently called David on a Sunday. He immediately dove in to get me scheduled. Sebastian called me before making an on-site visit. Patiently walked me through a simple troubleshoot and shazaam! I turned right on. A+++ to both of them."

"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!"

"I have used Air Ductors for years and always had good service. They maintained my older furnace and when it came time to replace it they also installed a new one. They recommended a good system and I have no problems with the unit over the past 10 years. They have honored coupons and given me discounts as a returning customer. Great company that I would highly recommend."

"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."

"Very pleased with the AC installation. The day they installed it, it poured rain all day, but the crew worked through it and got everything done. They were careful around the house and, even with the weather and the installation work, left everything clean with no mess. Good, professional service. I would definitely recommend them."

"Our previous gas furnace was only 14 years old (it was a replacement itself, but a generic "contractor's model," not a common name brand and probably inefficient). The gas controller died, which would have cost $700 to replace -- and we'd still have an old, inefficient furnace. At best, the old 100,000 BTU furnace might have been 80% efficient, and probably worse.
I called around and got a quote for a replacement from a large heating company in Woodinville, and a different brand -- but they insisted that we'd have to install a vehicle post for protection of the heater in the garage, in order to pass an inspection. They also did not explain how they would install the PVC exhaust pipe in our garage. The 95% efficient furnaces require a PVC exhaust pipe, which cannot attach to the existing metal exhaust that goes through the roof and that also handles exhaust from the water heater. Another large company in Bellevue wanted to do a 3-hour test of our entire house, to first determine what size heater to get. With that, and other reviews on Angie's List, I figured they would be more expensive, so I passed on that. After a quick look at our existing system, the other heating companies I talked with said that the same BTU output of a new efficient heater, combined with a variable or two-speed fan, would be the right size.
So I called Bassett Home Heating. John, the owner, came out the next day (a Friday) and offered two recommendations -- one for an 80% furnace (which could attach to our existing metal exhaust pipe), and one for a 95%. He explained how the PVC pipe could be routed along the top of the garage, and said nothing about having to install a vehicle post. I also liked the idea of a small family-run company, where you know who you will be dealing with.
The only potential downside was a scheduling delay, since we had no working heater. Because we have a wood stove that we have previously relied on for heat during storm outages, I decided to go with Bassett -- and am very glad I did. They are normally scheduled two or three weeks ahead at this time of year, but were able to rearrange their schedule and come out for the installation the following Thursday. We got the 95% efficient furnace. The PVC exhaust pipe looks and works fine, and they also installed a small pump and outlet tubing for the moisture that the furnace creates.
They called a couple of days ahead, and showed up right at 7:30 a.m. on the agreed day. John, his son, and another helper all worked on the installation, and did a great job. Complete installation took them less than 2-½ hours, and they showed how the new thermostat works -- it's easier than the old one, even though there are more features. I am extremely pleased with our new heating system; it heats the house much more evenly than the old system, and we aren't losing 15% or more of the fuel as waste.

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.
