"I was so pleased that the air conditioner repairman, Scott, who fixed my air conditioner on short notice did an exceptional job. We cannot express enough gratitude for his work. He arrived promptly and efficiently diagnosed the issue with my air conditioner. Despite the urgency, he remained calm and composed, assuring us that he would resolve the problem. True to his word, his expertise and professionalism were evident throughout the repair process, restoring cool air to our home. Not only did he fix the problem quickly, but he also took the time to explain what went wrong and provided helpful tips to prevent future issues. I highly recommend his services to anyone in need of air conditioner repairs. We were so impressed with their services that we recommended them to our son and daughter-in-law already. The woman in the office that scheduled this appointment, Jolene, was so easy to work with during a very stressful time of the year, the weekend with an upcoming holiday just a couple days away. Grateful for her help as well!"

"I called Airwise after my former HVAC contractor diagnosed my furnace as having a seized oil pump. They quoted me over $1,300 to replace the pump and perform other services necessary to repair my furnace. They installed the furnace less than 3 years ago and this was the second oil pump that supposedly seized. Needless to say, I fired them. When Airwise came to repair my furnace, the tech showed me the pump wasn't seized and stated it looked like it wasn't installed correctly. After spending less than an hour putting the burner back together correctly, we had heat again. I will be calling Airwise for my future HVAC needs."

"i desperately needed gutter cleaning the day before a major storm. I spoke with Dave initially and he worked with me to make it possible and sent out his crew by the afternoon to my house. His crew was so professional and worked very hard to make sure that all the work was done for me and they cleaned up and got rid of all the mess. This company could not have been nicer and helpful. I highly recommend them and am thankful that I found their business."

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.
