"It would be impossible to find a better guy to fix your AC than Ozzy, owner of Ice City AC, Inc. Our AC broke down in 96 degree weather and I never thought my young kids and I would make it through the night. Unbearable heat! The next morning I went on Homeadvisor in hopes of finding someone to help us repair our AC as quickly as possible. I was amazed to receive 7 or 8 return calls within minutes from AC companies offering to send out a technician first to provide us with an estimate of the costs required to make the repairs. One by one their estimators came and tried their best to convince me to hire them to install a complete new AC system for about $4000 which we knew was not needed. We have a 5 ton Rheem unit that is as good as it gets, and is only 7 years old. Then, a guy by the name of Ozzy texted me and told me that he owns his own company and personally does all of the repairs himself. He assured me that the other companies with more than 285 plus reviews would have to provide us with an estimate first and then schedule an appointment for the following day or two. When Ozzy arrived I immediately felt his real sincerity and unbelievable knowledge of air conditioning. He quickly found the cause of the leaks and quoted me a very reasonable and fair price and told me he would do all of the extensive work right now . . . on the spot and he promised to give us a 90 day guarantee on his invoice. He was here for 4 hours in the scorching heat and did a perfect job for us. God bless Ozzy. And I would recommend him as highly as possible."

"Team that did the work was very nice and professional and cleaned up after themselves. Air felt cleaner and fresher after they were done. Unfortunately our package didn't include cleaning the dryer vent. When I asked what that cost would be they said that they couldn't do that vent because they didn't have that equipment with them. Never learned what the cost would be."

"Lorenzo, the ARS technician sent to perform maintenance on our central air conditioning was thorough, professional and quickly spotted a part that would need to replaced that could fail at any moment. We have used ARS to both install and maintain our a/c units for 14 years and highly recommend them."




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.
