"Excellent! All old systems were removed and all new Carrier equipment was installed. This work was performed in May of 2018 so I have had a year to evaluate the heating and air conditioning performance. Other than some dampers coming loose and requiring service calls there were no issues with any of the equipment or installation work. Tyler is a great company with an excellent sales and service force. My installers were fantastic and there was some follow-up work afterwards like insect guards for the intake and exhaust of the furnace and installation of new wiring for a modern thermostat. Tyler completed all projects and I am completely satisfied and happy with their performance. I would HIGHLY recommend Tyler for all you HVAC needs. We did a complete replacement of both heating and A/C and Tyler did a fantastic job."

"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 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!"

"There was a snag at the beginning when they realized, after beginning to dig, that the AC unit was on top of the oil tank and they'd have to call someone in to move it before digging could continue. That delayed things a few days, but thereafter they did a good job of digging and were very careful with our trees. They also took care not to ruin the lawn with the machinery. The new tank and heater were quickly put in the basement with no problems."

"Advanced Professionals was very prompt in sending someone over to our office to assess the issues with our Air Conditioning unit. It was extremely hot weather and having an office full of doctors and staff was unnerving and frustrating. They were able to accommodate us right away and sent over their technician Rabi. He was very knowable and extremely helpful in resolving the issue. He was able to get us back up and running. He was very thorough and took his time to explain exactly what the issue was and gave recommendations on how to avoid this problem in the future. We are very confident in the service provided and will continue to use Advanced Professionals for any future services needed."

"We recently used Bell to replace our central air system in our home. From start to finish the job went smoothly. The initial consultation was done thoroughly and professionally, measuring each room of the house to determine what size units we needed, etc. The price quoted was fair and reasonable. Once we said yes a start date was put on the calendar, when the date came Bell was there as promised and the job was completed faster than initially thought. They were clean, left no mess anywhere, professional, knowledgable and nice. Bell did a great job and i would highly recommend them. I did not grade them on quality because we have not actually used the units yet but I'm sure the units will function perfectly next summer.

"Michael was very helpful with the sales process, providing helpful information on the options I had and offering a very fair price. We had a broken air handler and had to consider whether to replace just the air handler or do the compressor as well since everything was old and the Freon in our system was no longer in production. We ended up doing the full replace. Every step of the way, Celco kept me updated on the status of my order, including texts narrowing the timeframe for technician arrival. The techs/installation team were clean, courteous, professional and timely at every step of the process. Very happy I went with Celco for this job."

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.
