"My experience with Greenwood Heating and Air Conditioning has been entirely positive. From my free estimate appointment through finished installation, the process was seamless. Each and every representative of theirs has been exceptional. Trevor negotiated a very competitive, all inclusive price for the entire system and followed up on the day of installation to see how everything was going. The install was expertly performed by an industry pro, Andril, with 17 years plus experience. Follow-up has been exceptional. Greenwood Heating has earned my unequivocal recommendation."

"We have been customers of Bassett Heating for many years and always have been so impressed with their service. This is a family owned and operated business and you feel that personal touch. Whenever we have had a furnace issue over the years, John swings by our home quickly to make sure we are not left in the cold. John & his son installed a new furnace for us a few years ago and continued their tradition of great service. We schedule annual maintenance with them for our furnace to keep it in top working condition. When we decided to upgrade and add central air conditioning last year, it was an easy choice to go with Bassett Home Heating. John came by in February 2022, gave us an estimate for both installation timing & price, then returned with the install just in time for the summer heat in 2022. I highly recommend this company!"

"I wanted to pass on my experience with Evergreen who went the extra mile after my Mitsubishi slim AC started leaking water before the hot summer months. I had called a Kirkland company who came out diagnosed the issue and charged me an exorbitant amount. However after I informed them it was registered and parts were under warranty they dropped me like a hot potato and never called back. On the other hand Victoria at Evergreen called me regularly to update on the warranty and parts and scheduled a full day repair with Jesse, an excellent technician. He used appropriate PPE, educated me about the problem, even provided less expensive options, and finally completed the long arduous process of replacing parts and recharging the refrigerant all for a reasonable amount. Voila AC again! I would highly recommend this company - to do your job efficiently and technically correct, without overcharging or trying to upscale you. Peace of mind is priceless. RobinM"

"It went well. They came out on a Sunday afternoon (of course it was more expensive because it was the weekend and their emergency hours). They completed the repair, and then checked over our furnace while they were there. We also signed up for a reduced rate for a yearly servicing of the furnace. We then called back and had them service our air-conditioning unit and signed up for a reduced rate for yearly servicing. Very professional."

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.
