"The Appliance Guy (Justin) was exactly what we needed. Straight shooting, to the point, knowledgeable and professional. Repaired our 1930s antique Magic Chef that others quoted us insane amounts to get up and running. Justin came in, did a thorough cleaning, located the issue, repaired the pilot light system and got her up and running at a fair price. So pleased with the outcome of his work. Will 100% use again for future appliance needs."

"Airnizer is superlative in so many ways! Around thirty years ago my husband and I lovingly restored an 1840â  s row house. We didnâ  t see the need to air condition then. However, as the summers got hotter and hotter we realized we had a problem. Since we werenâ  t interested in central air and we didnâ  t want to alter the looks of our home with window air conditioners, we decided that a split system was the answer. We talked with several installers and were extremely impressed with Eugene Kobakâ  s understanding of our aesthetic and practical issues and his ability to anticipate technical concerns. Eugene and his two assistants did not disappoint us. Here are some of the things they did right: â ¢ Itâ  s a small enough company that the owner was on site all day, every day. â ¢ We felt confident that Eugene was a consummate professional who knew exactly what he was doing. â ¢ Eugene worked with us in placing the units as unobtrusively as possible. â ¢ He did an amazing job of making the ducts, etc. blend in with our architecture. â ¢ All the workmen were extremely polite and non-invasive. â ¢ These guys are CLEAN. They left as little mess as possible in such an invasive procedure. â ¢ Eugene and his company stayed with us until the job was finished. They arrived when they promised and worked a full day (sometimes longer!). â ¢ Eugene didnâ  t leave at night until each unit was tested for working perfection. I would recommend Eugene Kobak and his company Airnizer to my best friend. In fact, I plan to!"

"I wish there were a rating higher than 5...that's how good they were. Alex S. & Dimitri were professional, courteous, timely and explained every step. I used them to clean out the dryer vent, but will also be hiring this company to clean out the air conditioning vents as well."

"We recently had our home HVAC system installed by Fanoli and we couldn’t be happier with the results. From start to finish, the process was seamless—professional, punctual, and highly efficient. The installation was completed on time, and the difference in air quality and temperature control was immediate. Our family and guests have all noticed the improved and comfort. What really stood out was the attention to detail and the care taken to make sure everything was done right. It’s clear that he takes pride in his work. Highly recommend to any business owner looking for reliable and expert HVAC service!"

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.
