"This is just about everything I appreciate and value in a service provider. Our home has two heat pumps, and both were failing. Andrew quoted on both units in the spring, along with two other local providers. There was a pretty good spread between lowest cost and highest cost estimates, with Comfort Zone just shy of the midpoint between lowest and highest. From the initial discussion about the work involved and related equipment choices, I was sure Andrew was the provider I wanted. He spent time answering my questions during his initial visit and left with no pressure to close the deal. I had several follow-up questions which he always promptly answered via email or phone. His estimates offered multiple choices with the differences clearly explained. Comfort Zone replaced the first unit shortly after his initial visit. We just recently had him come back to do the second unit. Each time during his service visit, Andrew was professional and friendly and answered any question I had along the way. I love that the person who gave me the estimate is the same as the person who performed the work. You can tell Andrew is very proud of the work he does. The differences in interior air quality, interior and exterior noise level, and our power bill are all noticeable. I'd highly recommend Comfort Zone to anyone, just as a friend I trust had recommended them to me."

"I called them to go to my mother in law's property in the south end of louisville, kentucky. She just said the ac doesn't work. I warned them that she is a hoarder and house is a mess. It turned out there was a carcass of a dead cat preventing the blower/fan to circulate the air. They disposed of the carcass and got the a/c going again. They was very professional about the situation. And my mother in law said the technician was very kind to her."

"May 12, 2025 - This was our first time working with Greenwell since leaving a local competitor and Chad Russell was our technician. Our basement flooded and our sump pump needed replaced. Start to finish, Chad completed the job in less than three hours. I will be requesting Chad for all future work with Greenwell."

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.
