"Great work! Keaton was able to diagnose and estimate a fix for my furnace. Came out the next day to replace a part and do some regular maintenance on the furnace and air conditioner. Very happy with the work."

"Dave from Columbia came to my place in Portland from Scappoose on a same-day appt, for what I thought was a dead furnace. (I had tons of smoke flow into the home after furnace turned on.) Rather than just presuming the furnace was dead or even the problem, Dave poked around. He discovered the smoke was from the fireplace/chimey and the furnace turning on had pulled air from the chimney, reignited a smoldering log, and then filled the house with smoke. The problem was with the chimney all along, but Dave/Columbia did not charge me anything for the trip to Portland---or for diagnosing the problem---even when I called later to offer. Great service, great customer relations, great knowledge of how air moves through homes."

"Cris worked hard to repair our existing mismatched heat pump system. Once it was working again we determined that a replacement system would be the best route going forward. He did a fine job installing the new Goodman heat pump in this old house. It works well, and is very quiet. I was impressed with his attention to detail with all of his work. The install took several days, yet at the end of each day he cleaned up his worksite thereby making living through this disruption quite liveable. I have no problem recommending Solutions HVAC to anyone searching for a reputable business for their heating and air conditioning needs."

"Had a great experience with getting a new AC system installed with George and his team! Technician and salesman were very friendly, knowledgeable and informative. They laid down floor tarps everywhere so nothing got on my hardwood floor and carpet, which i loved! Very friendly and accommodating of my young kids in the house during the whole experience. After the install there was a small problem with the system, they were back the very next morning with zero hesitation, trouble shooting the problem and fixed it in no time. Checked back in as well to make sure i was happy with everything, that's says a lot to me about this team and how they take care of their customers."

"Nolan and Nate did a difficult job. They replaced my 1989 furnace with new and installed a ac/heat pump. They needed to mate the new slightly larger unit to existing duct work. You can't tell it was modified. The new outdoor unit is also first class. I would not hesitate to recommend them for any job. They are knowledgeable and.work their ask off."

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.
