"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."

"I had a relatively simply Air Conditioning problem, but needed it to be fixed ASAP (Sunday and Fathers Day to boot). Kirby was here within a hour ! and performed the repair in minutes. It was bit expensive, but considering the timing, well worth it. Shout out to Kirby and Belair Mechanical. I will definitely use them again if needed."

FAQs for air conditioning projects in Trumbull, 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.
