"We decided to use Shavitz Heating & Air Conditioning as the company for the install of our new furnace. What impressed us about Shavitz was their employees. They made the entire process a positive experience. Everyone that interacted with us had a friendly and professional demeanor. It started with the sales visit by Will Gutierrez who was a pleasure to deal with. He provided us with several options while never pressuring us to lean one way or another. He was patient with us and answered all our questions. His courteous approach gave us a positive view of the company he represented. The installing technician, Linas, and the tech that was assisting him only continued this professional trend. They both were equally as courteous. Once the work was complete, Linas made sure he answered all of our questions and that we felt comfortable with the operation of our new furnace and humidifier before he left. His patience was very much appreciated. He also made sure the area were the work was done was clean and all trash removed. Will Gutierrez followed up with us a few days afterwards to make sure all was well, and that we were pleased with the work and our new purchase. Our answer was a definite, yes."

"Phoenix HVAC has been great! I needed maintenance on my A/C having never done any on it for 13 years. Bob was great at explaining all that he was doing and he comped me on a part of the service because they had to reschedule me 2 times due to their schedules getting so busy with the latest extreme heat. Speaking of rescheduling, it's not common practice for them and Maggie, their office manager (and Bob) were extremely apologetic about it. I understood the circumstances. I was not in peril with no A/C and others were, so I was ok to wait a few days from original date. Customer Service was excellent, no pushy sales pitch and quality work! I've already recommended them to my neighbors!"

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.
