"We had a central air conditioning unit replaced. Chris was quick to respond via text message. He arrived exactly at the time he said he would, completed the job in less time than expected, ensured the unit was functioning properly before he left. He additionally offered tips and tricks for yearly maintenance on the unit. He was friendly, courteous, and reliable. We would definitely recommend him in the future."

"We chose Pro Heating & Cooling to do an oil to High Efficiency gas boiler conversion. Sean provided a clear and concise quote for the the full job, including a challenging removal of our oil tank. We needed the job done ASAP and Sean was able to accommodate our request and complete the full job in a day. His crews were prompt, and seamlessly coordinated to convert our combo forced hot water and air system while creating a much tidier and well laid out integration with the new boiler and indirect water heater. After the instillation Sean checked in and came to do minor adjustments to ensure the system was dialed in to run perfectly. Lastly, the pricing was great, and the instillation was designed to maximize the available Mass Save rebates for energy efficient systems. I'd recommend Pro Heating without hesitation (as I did to a friend/neighbor)!"

"The tech was on time, and he constantly put on shoe covers before coming through the house. He checked over my system and worked up a quote for 2 different plans of action, from lowest price to highest. He explained each issue to be addressed and there was no pressure as to what degree of intervention to take. I ended up having all of the recommended work performed, as it had been some time since I had the unit serviced. All of the work was done effectively and neatly. I am a facilities manager and know good work from bad, and this work was excellent..I would definitely hire them again. Also; the people who answer the phone and schedule service were extremely friendly and helpful."

"H L Bowman is by far one of the best service companies that I have dealt with. I got a call that the technician was on the way to my house. George showed up and got right to work. Found my problem and explained to me the best way to fix my issue. They did not try to sell me on any pricier fixes. George showed me what he could offer and explained what would be my best option. He was knowledgeable, informative, and explained everything so that I would understand what was going on. I am definitely going to be using them for all my heating and air conditioning needs. Top notch company. Would recommend to anyone needing this kind of help."

FAQs for air conditioning projects in South Easton, 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.
