"As before with previous work done by Absolute Temp Control, I wish there was a higher rating than 5. 2 days ago the air conditioning in the house stopped working. The Portland area has been enduring a series of 90-100 degree F days. John came out within ~1 hour of when I called. Turns out the HVAC unit is ~20 years old and on its last legs. John replaced the thermostat and fixed the wheezing HVAC’s other maladies. There are three of us formerly sweating humans and 2 no longer panting dogs here and we are all grateful to Absolute Temp Control for their speedy repair."

"They come once a year for the checkup on the furnace and air conditioning and make sure everything is set for Winter.
I have had them every year for years. It has always been good!
The air conditioner is still working and the furnace is still working, so I guess it is pretty good!"

"Just have to get used to the new furnace. "Ben" was nice enough to have the old air condition system removed without replacement, at my request. Customer service is very good."

"The bad air in that room has been a problem since I moved into the house and it has been hard to diagnose the problem. I am very grateful to Jim and Robert for their perseverance in figuring out how to approach this. The solution proved to be adding both the HRV and new thermostat, as well as adjusting the heat ducting. Now the air quality is very much improved and the heat is balanced throughout the house, where before it was either too hot or too cold upstairs. Robert is indeed a heating expert who also provided excellent tips for efficient operation of my furnace."

"Tom and his crew were fabulous. The most important thing was I completely trust him from day one. He was so honest and so quick. I called him he came out that day and within two days I had a complete new heat pump, air handler etc... I have had some medical issues and they never embarrassed me about the lack of repair in my home. What a great crew!!!"

"It went extremely well. Punctuality was perfect. Paying attention to details was perfect. Knowledge and professionalism were perfect. The price was competitive. We interviewed 5 different providers. Ultimately, Columbia seemed to stand out best. We tried it, and we were quite happy with the choice. The service cost was for two independent air conditioner systems ( we have a large, long house), and one new furnace."

"Air control systems work on time explained their process and proceeded to work quickly and most of all cleanly they left no mess while doing a good job they tookPictures of the process showing me before and after I would recommend them two others"
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.
