"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."

"We had Chris replace a decades-old gas furnace and electric water heater, as well as install central air conditioning. We talked to a few professionals in HVAC, and Chris seemed to have encyclopedic knowledge of it all. At a very fair price, Chris spent two days having the old stuff professionally removed, getting the new stuff (AC) wired up, and all the new equipment installed. This was a problem-free project from start to finish, and we would strongly recommend Chris to anyone with similar needs."

"Garett at One Call HVAC is without a doubt the best professional I have come into my home. My journey with Garett began in getting pricing to replace my furnace. Throughout that process Garett was up front, realistic, and reasonable with this quoting. The day after I signed the contract with Garett the old furnace died. I called Garett and even though we had a signed contract to replace it, he spent 5 hours trying to keep the old one going long enough until it could be replaced. When it became impossible to fix the old one Garett accelerated our time line to replace by a week and was able to coordinate all the components to get us up and running as quickly as possible. Throughout the process of working with Garett he found other system related issues with our heating system. He was able to explain in layman's terms what he thought the problems were, and systematically worked his way through the system until he uncovered the root cause problem. He then fixed this underlying problem at an extremely reasonable rate. if you are looking for a professional who is transparent in how they work, relentless in finding the actual root cause of a problem, and fair in pricing, then Garett and One Call HVAC is who you need to go with."

FAQs for air conditioning projects in Rochester, 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.
