"Onofreo Home Comfort Systems LLC was wonderful from the first contact in February 2026. Chris came and had a look at the house, the old system and asked what I wanted and how each room was used. He was so knowledgeable and personable. I really felt comfortable with his level of expertise. Mike & Patrick showed up each day ready to work. Mike was very communicative; letting me know when he arrived and left each day and summarizing their progress. My cat was not stressed out by their presence, which was comforting as well. The ladies in the office were so friendly and professional.The design was refined to a Bryant Heat Pump for the main level with an Ecobee Thermostat and a Bryant Mini-split in the basement. This meant that I did not lose any closet space for vents and each system is well suited for their purpose. I would definitely recommend Onofreo! They are a great company you can trust for your next project at an amazing price."

FAQs for air conditioning projects in East Haddam, 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.
