"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."

"Affordable HVAC repair service. You can actually ask them to do little extras at no additional cost. After I called them for emergency repair of our AC unit, they offered a complementary cleaning for the unit. Amazing customer appreciation. Totally recommended!"

"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."

"We were desperate to find someone to repair our central air conditioning unit. We were not able to move into the house and everyone that we called was not able to accommodate us because of the recent heat wave. All Weather was able to get a technician to us within 2 days. Nuri was amazing and showed my husband how everything worked and what repairs needed to be done. By the time he left, we had a cool house and were able to set up our movers. Thanks to Angie’s list, I found a reputable company that was reliable and efficient. We can rest easy! Thank you!!!"

"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."

"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.

FAQs for air conditioning projects in Norwalk, 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.
