"So many choices when your looking for a company to service your heating and air conditioning needs. When we reached out on social media for suggestions for a reputable and reliable company so many people highly recommended Advanced Mechanical Services that we wondered if it was for real. Well now you can count us among the believers. From the moment Deena took our phone call till Rob and Ian arrived at our home and completed the work on-site, these incredibly talented and professional people did their job on time, as promised, with courtesy and knowledge and quickly identified and fixed both our heating and air conditioning issues that three other companies that we paid big money to in the past could not figure out. Their reasonable bill for quality work was another surprise. And they were COVID compliant and respectful with masks AND gloves which made us feel comfortable (as senior citizens) having them come into our home to do work."

"I hired northeast heating and cooling to replace my aging heating A/C system. This was a fairly large job, seeing it was a Multi floor house with two independent systems running both upstairs and the main floor. They also explained to me how adding a heat pump system to the house would help make heating my house less expensive during fall and spring. They replaced the entire upstairs duct work and reconfigured the entire house to run balanced and efficient. I couldn't be any happier with the work that was done in the house I would highly recommend them. Thank you Guy's for your hard work and dedication to get this system working amazing!"

FAQs for air conditioning projects in Marion, 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.
