"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."

"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!"

"Great experience Justin, Nate & Timothy were awesome. Very knowledgeable, professional & curious. Aside from the cleanliness they delivered an experience. I highly recommend HL bowman if you want rapid service on your HVAC. Pricing was reasonable in my opinion & financing is an option. Keep in mind when seeking quotes for your HVAC repair/ new install you must consider performance over equipment, that is if your want a good system that will have a good run/life span."

"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."

"This time the owner Bill Ryan showed up with his guy. Under Bill’s instructions, they carefully examined the issue and showed lots of patience to try out different repair strategies. Although the problem is not completely fixed yet, the condition has been improved significantly. Bill showed genuine courtesy and respect to our home and keep following up the situation after leaving. As they promised while making the appointment, the re-visit was free."

FAQs for air conditioning projects in Stamford, 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.
