"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!"

"Pete, Jake and Jeremy and a couple of other workers from Cool Heat Mechanical did a great job on installing 3 central air conditioners and air handlers at my house over a 3 day period. They were neat, clean, on-time and did an excellent job installing the American Standard A/C and air handlers. The units are running great and improved my energy efficiency tremendously over my older units. Pete is extremely knowledgeable with his profession of installing A/C and heating systems. His pricing is excellent as well. We are also using them to install a new heating system within the next few weeks. We initially met with Dave who reviewed their products and gave us the pricing for the job. Dave made an excellent presentation of all their products and did not use any high pressure selling tactics. He offered some nice financing options through EnergizeCT that I was not aware of as well. I did have multiple vendors competing for the job and found that Cool Heat Mechanical was the most knowledgeable and had the best products and pricing in my area. I did a fair amount of research and this company is the one to use for your heating and cooling needs. I highly recommend Cool Heat Mechanical for your HVAC requirements."

"We hired Bertram to repair our central air. He arrived on time and did the repair. The repair should let us finish the season with the old season. We liked him, and have asked him to completely replace our system in the fall."

FAQs for air conditioning projects in East Hampton, 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.
