"Ali came over to our home when we called with a concern of the air flow in our central air conditioning system. He checked the return, the air flow, the temperature at all of the vents, and the entire system. It had more to do with the age of the system and gave us suggestions on how a different filter could increase the air flow. He did all of this and refused to take any money for his time. He is a true honest professional and someone that we would recommend to everyone."

"Royal Comfort installed our central AC system. It was completed on time and they were very clean, professional, and very fairly priced. They answered all of our questions and concerns and we continue to use them for our seasonal heat/ac service."

"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."

"I was very happy with my service call today! The repairman, Scott, was knowledgeable and pleasant and wore a mask and gloves throughout., so I felt safe, despite the pandemic. He serviced both of my central air systems and diagnosed the problem with the malfunctioning one and fixed it. By the time he left my house was already a much more pleasant place to be!"

"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."

FAQs for air conditioning projects in Greenwich, CT

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.
