"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."

"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.

"Celco was the best from initial phone call to install finish, never used them before, my hvac of 16 years was going to charge me $800.00 more and could not get me heat for 10 days. Celco offered me heat fans, and the job was done in 3 days from phone call to done. Jim Smith is the best, and install guys Bryan and sorry forgot your name were so polite and professional, others should strive to be 1/4 as good"

"They were great! Even found a way of adding a 40 gallon water heater to a smaller space. Which has been wonderful! They worked in a VERY tight space and got the job done! I highly recommend them! Will be using them to install my central air as well!"

"We used Schede to replace our central air conditioner. Overall, we are satisfied with the new system and the price but the customer service was not satisfying. I think they did everything we needed in terms of the mechanical work. But they should better train their office help. After we agreed on the installation date, I asked what time the crew would arrive that morning. They gave a vague answer so I asked again the next day. But they arrived two hours later than expected. After they were done, we discovered that we needed a minor adjustment and scheduled a time for them to come. An hour after they were due, I called and was told they were not coming that day. The next day was the same ? I called after they were overdue and was told they were not coming that day. They finally came the third day. The technician solved the problem and was apologetic. But it was quite frustrating that they did not come as scheduled and did not initiate the call to say they would be late or there was a problem."

FAQs for air conditioning projects in Old 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.
