"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!"

"I cannot say enough good things about Ryan to do him justice. Ryan installed a full house Mitsubishi Ductless Heat-pump (8 air handlers and 2 compressors) system for me. Of the 8 quotes I received from various local contractors, Ryan had the best price by far for the same exact system! He showed up exactly when he said he would and would always respond to my communications in a timely manner. He went out of his way to have make sure the install was attractive and clean on the exterior. I have absolutely nothing negative to say about the whole experience and could honestly keep going on about how pleased I am. He is an honest professional who I would highly recommend for any of his services, especially a ductless install."

"We hired Bill Aitken Heating to repair our gas furnace, we had an accumulation of water in the furnace pan. I called Aitkens Heating and received a call back immediately. They were here promptly at the time scheduled for repair. Mr. Aitkens had my furnace repaired within a half hour. He arrived with his helper and I could not be more satisfied with the work these gentlemen did. Bill took the time to explain in detail what he did for the repair. Bill Aitken is our GO TO man for any of our heating and air condition maintenance. I would like to add he was very reasonable. My husband was not available to over see this project so I handled the whole project from start to finish. BILL AITKEM HEATING LLC. comes very highly recommended by the Perkins family."

"Jeremy and his team gave me the best contractor experience I've ever had. He listened to what I wanted, provided a fair quote for a central A/C replacement (air handler and condenser), and never pressured me or tried to upsell. In passing, he mentioned a heat pump option for the shoulder months to reduce oil use, but that was it. After doing my own research, I called him back with questions, and he took the time to walk through the pros and cons honestly. There was no sales pitch, I actually asked for a quote heat pump quote too, because I saw the benefits myself. I ultimately chose the heat pump and appreciate that Jeremy gave me the information needed to make an informed decision. His crew was fantastic, friendly, professional, and thorough. They removed the old system and completed prep work on day one, then finished the install on day two and walked me through everything. Great communication, great pricing, great workmanship. I highly recommend Jeremy and his team!"

"I highly recommend ASL Mechanical! Austin recently replaced the compressor in my AC unit after I had an extremely frustrating experience with two other companies. One company did a poor job with the wiring and was unreliable with scheduling, while another recommended replacing the entire system?even though the unit is only four years old. Austin was a breath of fresh air! His professionalism, knowledge, honesty, and fair pricing were greatly appreciated. He took the time to properly assess the situation and provide the service that was actually needed. It?s refreshing to find a company you can trust. I wouldn?t hesitate to recommend ASL Mechanical to anyone looking for quality work and dependable service!"

FAQs for air conditioning projects in Salem, 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.
