"Airco is a great family-owned and operated business, very fair and knowledgeable. They replaced our forced air central heating system (oil) in a day, and were quick to respond and get to work despite how busy things were during the January cold-spell. I would highly recommend for your heating and cooling needs!"

"We are overall very happy with the project. Sila had to install a high velocity air conditioning system in very limited space. They provided a timely quote and showed up and did the work professionally and on time. There were a few hiccups, such as the installation of the hatch to the attic space, but Sila’s carpenter agreed to fix the problem at no additional cost to us, so I consider that to be excellent service. After two weeks, the system has been performing exactly as we hoped."

"We've used Atlantic Heating and Air Conditioning for over 10 years for regular air conditioning maintenance/service and repairs. They also do service/repairs for our heating system. Recently, they provided valuable advice that allowed us to fix a thermostat malfunction on our own, saving us cost of a visit. We've always been satisfied with this company - visits were easy to schedule, staff were knowledgeable, work performed was well done."

"My central AC unit has been broken for several years. intermittently working during hot summers. I've had several HVAC companies come to diagnose and all of them told me different things: replace the whole system, new lines, etc. potentially costing tens of thousands of dollars. So I decided to troubleshoot by myself and pinpointed the issue: the filter dryer needed to be replaced. No company wanted to do this small job. I called Emerald HVAC and told them about my issue, they sent in José, who diagnosed the issue to be what I said. He replaced the filter dryer and the AC unit works perfectly now after several years! In short, Emerald HVAC will be my first choice for any HVAC work in the future. They are honest, professional, and reasonably priced. I recommend them without reservation!"

"From start to finish we have had a great experience with Rodenhiser. Rick Picard came out to look at our system and provided a few estimates for different options while on site. We needed most of our 35 year old central air conditioning system replaced. The communication from the company was impressive. We always knew who was coming and when. They helped with the initial MassSave paperwork and even submitted all of the rebate paperwork for us when the install was complete. Good luck finding another company that will do the same. Our installers (Brian Heno and Dylan E.) arrived on time every day. They were professional, kept us updated on their progress and cleaned up daily. Two very hard working guys. They did a great job with the install. It looks and performs fantastic. We could not be happier with the system now that it is installed. We chose the correct company to work with. This is our second time having Rodenhiser complete a major install at our house. We had them install a furnace several years ago. I highly recommend them for your HVAC needs. Thank you."

"Our AC unit failed at the end of last season. Jason from Milltown came to our house to review our needs and made a recommendation to our satisfaction. I reviewed all of the data supplied and being an engineer I was totally satisfied with their recommendation. In addition the price was better than I expected. They came early this morning to install a new AC unit with a heat pump. Scott and Joe were are installers plus three others showed up later to support them. My wife and I are in our mid seventies on a fixed income. When our existing system failed and being confined to our home, we had our backs up against the wall. Milltown Plumbing & Heating respected who we are and bent over backwards to help us to have a comfortable home during this pandemic. We are truly grateful to Milltown Plumbing & Heating for helping us and we highly recommend them for your AC and heating needs. Wes M"

FAQs for air conditioning projects in Bolton, 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.
