"Incredibly professional and helpful! I bought my first house last summer (my husband and I are long distance) and quickly found out how hard it was to manage a house on my own. I realized early on that the AC didn’t work well and my boiler would spark flames if I attempted to turn it on. After living with just a few space heaters in the dead of winter and 800 electric bills, I finally decided to do something about it. A good friend recommended these guys and just after one chat, I immediately trusted them. They took the time, no matter what time it was, to answer all of my questions and prepare me for the investment of a brand new system. They finished the job in a single day, even working around my crazy schedule. They are AMAZING! I can’t thank them enough for all of the time they spent with me explaining the system, how it works, and even what filters to purchase and where to change them! I’m truly blessed to have been recommended them. PS: they still check in with me about it! :)"

Getting the job done the rite way and building great relationships with clients
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.
