"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."

"I highly recommend Pro Heating & Cooling . The owner recognized my need for the timely installation of a new boiler system, when other companies callously gave me a window of 3-4 weeks in the middle of freezing weather. To aid the process, the owner also took care of the paperwork needed to apply for a loan, and rebates. This was a complex job, but this company has the teams/expertise necessary to complete the work efficiently."

"My electrician from Cotti-Johnson HVAC was a master electrician. If you get him, you are getting the best. I went with the most expensive work package of the 3 that were presented. First off, it was pricey. I knew that going in. I want Cotti-Johnson to understand that I am serious about a working relationship with them. I feel I have done that with their electrical department. Now, if I need their plumbing or HVAC service, our relationship can build off the first experience."

"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 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.
