"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."

"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."

"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."

"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 finished our basement last year. At that time we upgraded our existing furnace so that we can heat both main floor and basement. Another HVAC contractor (not Bell Heating) performed this task and added two zone dampers for the two floors. After this work was complete, the main floor was always overheated. Since the original heating contractor refused to fix this problem, I contacted Bell Heating. George from Bell Heating explained that the zone damper for the main floor is stuck at open position blowing hot air all the time. The original zone damper was in a very difficult to reach position above a corridor and there were gas and drainage pipes surrounding it. George and his supervisor worked very hard to cut ductwork to extract the old zone damper and patched the hole. They ordered a new one to replace it. When the new one arrived, they placed the new zone damper in a position which can be easily accessed. This work involved repeated visits from Bell because the damper was not a size that is readily available in market. Now everything is working fine and main floor heating is again controlled by the thermostat as it should be. I am very pleased with Bell heating for fixing this problem."

FAQs for air conditioning projects in New Canaan, 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.
