"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!"

"The salesman came to our home & was very professional & knowledgeable. We got several quotes but decided to go with this company because of the knowledge of the salesman. The technicians came to install the air conditioning on time, wearing masks, and did a fantastic job. There were no problems whatsoever with the install. They also were very neat & cleaned up after they were done. I definitely would recommend this company!"

"Chris provided unbelievable service during a recent difficult outage of my HVAC system. He spent extra time and responded far quicker than any other contractor. He even took a part home, refurbished it and removed the rust and painted the piece exposed to the outdoors. I’d hire him again in a second!"

"Jeremy, the owner of Parker Home Services quickly - within hours - returned our request for service. He showed up early for the quote appointment. There was no BS. His quote was thorough and accurate. Jeremy removed and replaced the central AC units in a day and a half. His attention to detail is superb. Once the job was done, he brought me over to make sure that the AC worked as intended. While checking vents we noticed that some were not supplying air. Jeremy went back up in the attic and located three supply ducts that had been removed (by previous workers) from their registers and he reinstalled them. He also found a separate supply duct that had a board laying across it, constricting air flow. All of this was above and beyond what the initial job called for and shows that Jeremy takes great pride in his workmanship and making sure his customer is satisfied. We will have them back. Thank you PHS!"

FAQs for air conditioning projects in Old Saybrook, 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.
