"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 have been in our home for a little over a year and thought it best to have our furnace serviced especially since we don't have a detailed history of service. Frankie D showed up 5 minutes early for our appointment which was fantastic. Frankie was quick, clean and gave me a once over on the age and condition of our furnace. We talked about when the next service would be due. I couldn't have asked for a better experience and I am thankful that we now have our go to company for anything furnace related."

"Diagnosis and repair were straightforward and the talented Mike, who has done other great work for us on our ACs, had a replacement pump in his truck. Swapped over in under an hour. Cost of the repair was quite high, mainly due to very high price they charged for the pump. A Taco pump that I could buy for $175 was priced on this repair at more than $500. I get that it was an urgent situation and I’m happy to pay reasonably for the response but that mark-up bothered me. I called the office, had a long talk with the owner; sadly, she offered no consideration at all. Yes, it’s hard to find and keep skilled techs, but now seems that most HVAC firms have a business model like a car dealer’s service dept, far more corporate, less flexible or customer-considerate."

"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."

"On the day that the heat pump is installed, request that Paul or Daniel be there at the end of the installation to go over all the details on how to operate the complicated thermostat. Paul and Daniel will answer all questions, but those who install the pump do not handle thermostat questions. And the maker of this thermostat, like the makers of all modern thermostats, does not provide a manual or a clear explanation on-line. This lack of manual and on-line instructions is exceptionally frustrating, which is why staff like Paul and Daniel are essential on the day of installation."

"Service guy was very thorough and explained everything he did. Also what he would recommend to be done come spring. Like the idea of a service plan they offer coming twice a year to check heat pump. Would totally recommend them to others having heat pumps."

"We chose Pro Heating & Cooling to do an oil to High Efficiency gas boiler conversion. Sean provided a clear and concise quote for the the full job, including a challenging removal of our oil tank. We needed the job done ASAP and Sean was able to accommodate our request and complete the full job in a day. His crews were prompt, and seamlessly coordinated to convert our combo forced hot water and air system while creating a much tidier and well laid out integration with the new boiler and indirect water heater. After the instillation Sean checked in and came to do minor adjustments to ensure the system was dialed in to run perfectly. Lastly, the pricing was great, and the instillation was designed to maximize the available Mass Save rebates for energy efficient systems. I'd recommend Pro Heating without hesitation (as I did to a friend/neighbor)!"

FAQs for air conditioning projects in Wellesley Hills, 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.
