"I looked at a number of different options and they had the best pricing and they also specialize in just doing central air. So they were also sort of a plumber and gas fitter, anything like that, and so they really specialized in what I was looking for. So that is sort of their core business. They were good and they did a very nice, clean job. The house was built in 1901 and so they did a great job of removing the old radiators and radiant based heat systems and replacing it with a new central air set up."

"Shawn did an excellent job of replacing my 32-yr old heating system with a 5-zone, Buderus G115, Riello Burner, SuperStor Water Heater, and a "fan-in-a-can" air intake (as furnace is in an enclosed basement closet). He really knows his stuff! He is organized and does a neat, professional job. When he was finished, he tested and marked each zone with me for future identification. I highly recommend Congers Heating & Cooling for quality workmanship and a competitive price."

"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."

"My house had very loud banging whenever the heat was on. I needed the line purged of air. initial cost was 500.00! For 20 min of work. The technition that gave initial qoute then revised the amount to a more reasonable 220.00 He was informative and helpful. Had they charged that much I would have felt like I was robbed. They did a good job."

Customers say: Super punctual

"My whole experience in dealing with Milltown was nothing but pleasurable. Their office staff are so professional and courteous. They were very accommodating to my scheduling needs, and even called a half hour before their actual arrival. My air conditioning unit is a bit old and it needed more than just a tune-up unfortunately. The servicer was very helpful in letting me know exactly what was wrong and how I he could fixed it and keep the cost down. He also showed me things about the air conditioning unit that I could do on my own to keep it running efficiently. I was very happy with everything Milltown Plumbing did for me and I would highly recommend there services."

FAQs for air conditioning projects in Lunenburg, 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.
