"Excellent. As an out of state owner, reliability and integrity of repair persons is always a concern. Bart sets the standard for excellence. I have relied on him for many years to insure that the air conditioning is functioning, and in an emergency when it breaks, he always responds in a time that less than the initial estimate. He is honest and communicates with me regularly as to his arrival, the nature of the issue, the cost, when the repair is complete and issues to watch out for in the future. I cannot recommend him highly enough. As there have been many service calls over the years, please note that the cost of service has differs, but has always been reasonable."

"I recently had my air conditioning unit serviced by Airmetrix, and I couldn't be more impressed with the professionalism and efficiency. From the moment I called to schedule the appointment, his customer service was friendly and helpful. He arrived on time, was thorough in inspecting my unit, and explained everything in detail. He even took the time to clean the system and ensure it was running smoothly. The pricing was fair, and I can already feel the difference in the air quality and cooling performance. Highly recommend Airmetrix to anyone in need of HVAC work!"

"Very impressed with initial visit. We needed someone to come out on a Saturday. Shaun looked at entire system, not just the air conditioner. Quote was in line with othe providers. Installation scheduled quickly (for Monday), installers were very professional. I have already recommended this vendor to friends."

"I originally called my regular service company to come out and look at my ac and they told me I had a bad compressor and should replace my 7 year old system. I called Prestige for a 2nd opinion, and they said my compressor was not the problem. They also told me that my system was still under the manufacturers warranty. They repaired my system for under $300. I will definitely be calling them if I have a problem in the future."

"I am better informed about air conditioning than most homeowners and occasionally do my own repairs. However this was for a new installation. Excel did great work. SIlviu is a pleasure to deal with, gives the straight facts, and does not oversell. I recommend Excel without reservation."

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.
