"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 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!"

"Return Air Vent Move - Tech cut a crude opening in the ceiling framework which did not properly fit the elbow duct he installed. Did not clean up sawdust and did not replace insulation he moved. Displeased with the quality of workmanship of their technician. Repaired the sloppy workmanship myself due to time constraints for my construction addition. Bowman owner said I should have called back to let them fix it. Plumbing for Half Bath - Owner arrived on Oct 9th, 2018 to give me a free estimate to do the job. He did not like the fact that I mentioned the poor quality of the Return Air Vent Move job. After reviewing my half bath requirements, he left but never got back to me with a quote for the job. Called HL. Bowman approximatley 3 weeks later on Oct 29th, 2018 to inquire about my quote. Rep. said he couldn't find anything regarding my quote request. He said he would check on it and get back to me. As of Nov 1, 2018 I have still not received a return call or my quote; very dissapointing. Will not use this vendor for any of their services. Got a quote from H.B. McClure Plumbing to do the rough in plumbing; $2100. Will probably use them because I have been happy with the quality of their workmanship in the past."

"????? 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"

FAQs for air conditioning projects in Allston, 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.
