"Our Burnham boiler has been giving us issues this winter after just purchasing the new house over the summer. We've come home a number of times to no heat and a cold house, but had luckily managed to YouTube our way into figuring out fixes. This time unfortunately we couldn't figure it out and needed to search for an HVAC contractor. Green Energy was the first company I could even get to answer my call. At 9am Melissa was able to set me up with a day of appointment, Terry was at our house by 1pm. Since this boiler type is still new to us, Terry was great with explaining the workings of the equipment, and just some general tips for upkeep. It ended up being a simple fix with a loose relay, however I would of never been able to figure that out on my own. Terry ended up also doing a general servicing and cleaning of the unit, which they recommend annually to help the equipment last longer (we're positive the previous owners never did it). I would highly recommend Terry, he was knowledgeable and overall good guy. We also plan to sign up for their annual membership program and use Green Energy moving forward."

"My 30 year old boiler, with much fanfare chose to conk out, leaving me without heat as an impending snow storm was in the forecast. After getting outrageous quotes from another HVACs for a new boiler, I lucked out in finding Pro Heating. When Sean learned I was without heat, he gathered his A team and within a couple of days (other companies were saying it would be weeks)installed a high efficiency boiler that was less costly and is far superior to the less efficient boilers that the other companies quoted. Sean and his team are incredibly knowledgeable and professional. I highly recommend Pro Heating and Cooling, and have done so already to friends and family!"

"Great experience Justin, Nate & Timothy were awesome. Very knowledgeable, professional & curious. Aside from the cleanliness they delivered an experience. I highly recommend HL bowman if you want rapid service on your HVAC. Pricing was reasonable in my opinion & financing is an option. Keep in mind when seeking quotes for your HVAC repair/ new install you must consider performance over equipment, that is if your want a good system that will have a good run/life span."

"My AC wasn't blowing cold air. Bernard & his assistant came within a couple hours, diagnosed the problem and had my AC back to normal by the middle of the afternoon. It's been working great since then. Both men were very polite, patient and helpful. Would definitely use them again."

"We selected Rodenheiser to install a 5 head Mitsubishi air/heat/fan system. The crew was nothing short of amazing. Dylan the crew leader was knowledgeable, respectful, thorough, and terrific. You can actually feel and see the teamwork as the job progressed. The installed carpets at the front door to clean boots, all wore masks and distanced, cleaned up after themselves, and more! We could not be happier with the install team. Also had a great experience with Ross who came out, specd the system, managed the quote, and oversaw all details. Amazing. These guys are PROS! The difference in how they approached the system design and had all the details worked out; made the other folks we talked to look like beginners. These guys have dedicated teams that install MITS and are the largest (and best I think) in that business. If you are thinking about doing a MITS Splits system, talk to Rodenheiser. btw: our house is an old house and MITS fit in great!"

FAQs for air conditioning projects in East Weymouth, 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.
