"From start to finish it was a very positive experience. Shane explained everything and answered all my questions when he came out to give me an estimate on the project. Brandon and Brian showed up on time, completed the job in a timely manner and cleaned everything up when they were done. They showed me how to operate my new mini split AC system before they left. Shana was also very helpful when I called the office. The project turned out great. I would highly recommend Onofreo Home Comfort Systems."

"I was able to get a same-day appointment, and Abraham showed up right on time. He took a look at the system and confirmed that the furnace was running as expected, and he didn’t find evidence of a cracked heat exchanger. I was hoping for a definitive answer as to why the air wasn’t flowing out of several of my vents, but he was only able to confirm that it wasn’t due to the furnace itself. I may have clogged or separated ductwork behind the walls, but he wasn’t able to diagnose/confirm. At least I know the furnace itself isn’t the source."

"H L Bowman is by far one of the best service companies that I have dealt with. I got a call that the technician was on the way to my house. George showed up and got right to work. Found my problem and explained to me the best way to fix my issue. They did not try to sell me on any pricier fixes. George showed me what he could offer and explained what would be my best option. He was knowledgeable, informative, and explained everything so that I would understand what was going on. I am definitely going to be using them for all my heating and air conditioning needs. Top notch company. Would recommend to anyone needing this kind of help."

"During the hottest week in several years, THEY SAVED OUR BACON by 1) responding, 2) promising and 3) delivering. Specifically, they showed up on Tuesday, installed the new compressor on Wednesday, removed the defective valve in the attic (not an easy job with our outdated ductwork) on Thursday and installed the OVERNIGHTED special order replacement valve on Friday. New system works great. FYI, other numbers we called during the emergency said, "two weeks at the earliest.""

"Celco was the best from initial phone call to install finish, never used them before, my hvac of 16 years was going to charge me $800.00 more and could not get me heat for 10 days. Celco offered me heat fans, and the job was done in 3 days from phone call to done. Jim Smith is the best, and install guys Bryan and sorry forgot your name were so polite and professional, others should strive to be 1/4 as good"

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.
