"Jared (New Era) was fantastic. Not only did he work quickly and efficiently, he made sure I was fully informed about what he was doing and why - he told me what he was GOING to do, told me what he WAS doing as he did it, and reviewed what he had DONE when it was finished. And he was a really nice person, which is definitely a bonus when someone is going to be working in your space for the better part of 8 hours. Jared ran a natural gas line for us from the furnace area to the kitchen so that we could put in a gas stove. We just got the stove itself yesterday (finally!), and the whole system is working beautifully. Thanks, Jared, for your wonderful work!"

"Matt serviced my HVAC system. He most recently has installed a tankless water system. Matt is professional, shows up on time, is knowledgeable, and does not upsell. I highly recommend Airflow Alchemy. You won’t regret it."

"Very professional work under trying conditions!!! Loved this professional!!!"
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.
