"I bought my unit from NETR in 2018. It worked fine until we discovered it wasn't blowing any cold air. I made the big mistake of hiring someone a family friend recommended and they diagnosed it incorrectly and then basically disappeared on me. Anyway, it took a few weeks but they repaired it today and I was impressed with their courtesy and getting the job done very quickly and successfully. I felt like I was being dealt with honestly. Thanks, Jared and Jack. I should mention I paid about $300 for the refrigerant today. I don't know what the final cost will be but probably a bit over $1000."

"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."

"My experience with NV Heating and Air Conditioning was incredible. Keith the owner came over to assess the job and took the time to explain how the system worked and went over of the various options. He got back to me in a timely manner with a fair price. He assured me the install will be done neating and without incident and I would be happy. They did not disappoint! I was extremely happy with the results. Ron the project manager was a down the earth guy that was professional and willing to explain things to me as the job was progressing. The 2 young workers Richard and Nathan were both awesome. They were both good workers that got the job done without issue. I really enjoyed speaking to them and they were helpful in explaining things to me when I had questions. From the office Manager "Dawn" down to the work crew NV Heating and air Conditioning was top notch. They had it all with a fair price and high quality installation. Add to that Keith the Owner is a Veteran!"

"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."

FAQs for air conditioning projects in Millbury, 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.
