"Review by Claudette L. in Fall River, MA Project: Removed Whirlpool central A/C & Installed Concord central air conditioning condenser. Rick was excellent, pleasant, skilled & responded quickly after my initial request. He was very proficient, addressed all of my questions & concerns. He also managed to schedule my work quickly to complete the job & be sure that my new A/C was working properly before his departure. He was also reasonable with his original quote for his services & did not change this price upon completion. I will absolutely call Rick for any future heating or air conditioning issues. & would highly recommend Rick Maloney heating & cooling to friends & family."

"Chris installed two Mitsubishi mini-split air conditioning/heat pump systems in our home. Chris responded quickly to our request for a proposal. He came to our home in a few days, did a thorough review of our options, explained how the systems work and patiently answered all our questions. He sent us his proposal the same day and his estimate was very reasonable. He installed our system in one day even though it required him to work late into the evening due to a delay in the delivery of the equipment caused by a major traffic accident. Chris is very professional and a pleasure to deal with. We recommend him without reservation."

"I appreciated being able to speak with someone in the office to explain my situation (leaking water heater), and having someone come to my home so quickly to go over my options for dealing with the problem. Dylan, Aaron and the entire crew were so professional and knowledgeable about the on-demand hot water system we chose to install. They were a pleasure to work with, and I would highly recommend them to friends in need of similar services."

FAQs for air conditioning projects in Assonet, MA

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.
