"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!"

"Peter did an excellent job tuning up my A/C system. He was extremely diligent in making sure my A/C unit was up to speed for cooling for the upcoming summer weather. I know I will most likely need a new system installed in the near future as this one is on it's last legs. I know who to call when I need a new A/C unit installed and it will be Peter!"

"I highly recommend J. Griffin Heating and Plumbing for any install, repair or maintenance needs you may have. Jeff, the company owner, and his team recently replaced my very old home heating system with a high-efficiency boiler. I placed a request through Home Advisor and received a call back from Jeff the very next morning. Jeff was at the house that evening and spent an hour or more with me explaining my options in detail and answering all of my questions. I inherently knew, from that meeting, that I was dealing with an honest guy. He spoke with pride about his family and that his wife and boys are key to the success of the business. I expressed to Jeff that I was concerned about the safety of my current furnace and wanted to get it done as soon as possible. They made room in their busy schedule and were at my home, ready to go, within a few days. They were clean, neat and caused very little disturbance to me and my family during the install. Jeff and the guys were friendly, polite and conscientious. When the job was done, Jeff took the time to educate us on how the the system works and what to look for. Sandy runs the office and was very helpful with the entire processâ ¦.from scheduling the initial appointment to getting the contract together to helping me through the rebate process. Top notch service. It was just a great experience from beginning to end. You cannot go wrong hiring these guys. They are the best."

"Our oil burner cracked and needed to be replaced. The burner heats our water, so we would be without hot water until we replaced the burner. Steve Chamber arrived quickly, provided a competitive quote and got the oil burner installed and our hot water restored within a few days.. The final bill was exactly what was quoted and they cleaned up after themselves, even removing the cardboard boxes. I highly recommend Chamber HVAC and love that it is a family owned and operated business!"

"My wife and I recently had our furnace replaced by Rodenhiser Home Services. The initial problem was the igniter on our 22 year old system failed. We called Rodenhiser on Saturday morning, November 14, and although we were not a current customer, they stated they would schedule a technician to come to our home on an emergency basis. The technician was onsite within the hour and confirmed a failed igniter. Since we were going to replace the system anyway due to the AC condenser having failed the year prior, we asked to speak with Rick Picard, the HVAC Specialist. Rick discussed with my wife and I our options and worked with us to get the product we wanted installed as quickly as possible. Rick was extremely helpful throughout the process of describing which systems were available, and assisting with the securing of the MassSave Heat Loan Program. On the day of installation, we were greeted by Tyler Durran (Lead Installation Tech), and Matt (Apprentice Installation Tech). Both fine young men who were polite, courteous, and conscientious of their work. Both Tyler and Matt were professional and exhibited a solid work ethic and displayed genuine pride in their work. We were also greeted by Tim (Lead Electrician) and Alex (Apprentice Electrician) who were to handle the rewiring of our new furnace. Upon inspection of the Service Panel, they found the source connection from our electrical provider to be loose within the service panel and not making proper contact. It was a fire hazard and we were fortunate that the problem was identified. A call was placed to their manager, David Cassidy, who arrived and advised us of our options. We chose to have the entire service panel replaced, and David did an excellent job of dressing the cables and providing a neat service panel. He also took the time to use the current circuit breaker mapping we had to rewire the new breakers. All Rodenhiser personnel were professional and conscientious of their work. We would recommend Rodenhiser to those in need of the services they provide"

FAQs for air conditioning projects in Middleton, 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.
