"This was the best experience with a company that I have never had come to my home before. I run an Airbnb out of my residence and my central air stopped working in the middle of a heat wave. I called all the service people in my area and no one could come for 2 weeks. I was panicked! I found Cawiamca on Angi's list. They are located in Saybrook CT. I wasn't sure they would come all the way to my home in Mystic. The owner himself called me and had someone come out THAT VERY DAY!! And the problem was fixed within an hour. I can't say enough good things about this company and the service man that came out. Fabulous, friendly, and expert service! I highly recommend them!"

"Bill was amazing from the start. Within an hour of submitting an inquiry through home advisor he immediately contacted me. Not only did he have questions but also provided minor troubleshooting steps to ensure it wasn't anything small causing my forced air system from consistently power cycling. Highly recommended."

"It went great!! If I could give more than 5 stars I would. Jack always keeps us posted on every step of the job, does outstanding work, the price is more than fair, and leaves the work site in better condition then when he started. You can't go wrong by hiring EREG property management. I will definitely hire him again. Good job."

FAQs for air conditioning projects in Mystic, 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.
