"I whole heartedly recommend Airco. Their team was experienced, skillful, friendly and professional throughout the duration of this job, from Joe's first visit to my home to discuss air conditioning options to Derek and Cam's final touches on the duct system. I had complete confidence in them, as well as in Steve, Danny, Frank and Patrick. Additionally, Airco's connections to MassSave and Commerce Bank meant financing and payment options to suit my budget. No more hauling loud and heavy window a.c. units up from the basement. Instead, I am enjoying consistent cooling throughout my home with no noise whatsoever. I am a very happy customer!"

"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."

"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."

"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!"

"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."

"????? I highly recommend Juan David and his team! They installed a complete central air conditioning system in our two-family home, and the entire experience exceeded our expectations. From start to finish, they were professional, efficient, and incredibly knowledgeable. The installation was completed much faster than we expected, and everything was done with great attention to detail. Both units are working perfectly, and we couldn?t be happier with the results. What truly stood out was their kindness, honesty, and dedication to doing quality work. They offered a fair and competitive price with no surprises, and the value we received was outstanding. If you?re looking for a reliable HVAC company that delivers excellent workmanship and outstanding customer service, Juan David and his team are the ones to call. We are extremely satisfied and would absolutely recommend them to anyone looking for a five-star experience. Darron &Cristina"

"I called them as I could not re-light the pilot light on my water heater. They explained that there was a call out fee which was reasonable and they said the engineer would be there between 4 & 7 that evening. He arrived at 6 and fixed the water heater in 10 minutes but checked first that I understood that a fee was due - a good experience"

FAQs for air conditioning projects in Belmont, 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.
