"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."

"SumZero Energy Systems have been excellent in the last several months with supporting the replacement of my air conditioning system in my old condo as well as servicing my furnace. A price comparison with other local companies also prooved SumZero Energy Systems offered the best price. When I purchased a home a few months later, I called them to take a look at my air conditioning system and furnace because I felt as though they had provided such excellent service in the past. It was a no-brainer to ask for consultation regarding the heating and cooling systems in my new home! When I contacted them for assistance or consultation, they are usually quick to respond and provide appointment times had a very convenient window! They have shown up on time to all of the appointments I have had. David S. has always taken the time to explain everything thoroughly and answer all my questions. I highly recommend SumZero Energy Systems!"

"In the heat of the summer, our air conditioning shut down. I was worried that I was going to have to spend several thousand dollars to replace it. G & C came out to diagnose the issue and had it solved within an hour. They educated me about Maintainence so that this doesn’t happen again. Very happy with the service and professionalism. I will definitely be using them again!"

"I am writing to recommend the excellent work of Metrowest Minisplits based on our recent experience with the install of 4 minisplits and outdoor heat pump system. Our house is heated with oil and I wanted an alternative clean heating source and could not be happier with this added system to our home. No more noisy window AC Units. These minisplits are so quiet as well as the outdoor unit. Jamie and Allan walked through our home measuring each room, wall to wall, ceiling to floor, providing location and unit size recommendations and did not over sell. They took the time to review the outside of our house and listened to my concerns for placement of outdoor duct work and unit location. I wanted to use a local contractor who would also be installing the product and would not use a third party contractor. Jamie took the time to come back after they where finished installing units when everyone was home to show us together how to use the remotes, how to clean filters, adjusting air flow and explain the proper use of the system. Thatâ s why I would recommend Metrowest Minisplits. Great customer service! The Brazeau, Southborough, MA"

"Mike at O'Hara Heating and Cooling is outstanding! He was quick to come out and look at what I was looking to have done. He was professional, courteous, and honest about his recommendation. I have repeatedly hired Mike on many projects including: replacing both the indoor and outdoor AC Condensers after they failed, relocated the condenser line (due to remodel), replaced the thermostat, and replaced the baseboard heating system in my home. All work was completed on time and within budget."

FAQs for air conditioning projects in Blackstone, 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.
