"

I called Kris U. in a panic because an unethical contractor had totally messed up our very expensive HVAC system, and the condensers had been sitting unconnected for 18 months! Called Sila, they had no idea what to do. Called Kris and he sent in Gregg H. to reconnect everything, drain the condensers and recharge them again. He did a great job and it turned out we did not have to buy new condensers -- hooray!

I highly recommend this company, since no one else was willing or had the inclination to tackle this.

"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 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."

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."

"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!"

"Ken came quickly after I reached out. He helped me better understand our current AC system and made sure there’s better airflow to our first floor, which was the initial problem. He also helped me figure out that we don’t have AC to our basement and he offered some solutions. Thanks Ken!"

Customers say: Quick response

"Taylor uncovered the problem with my central air in a fairly short time. A previous Heating contractor disconnected the a/c wiring when they installed a new heating system. That contractor didn't handle a/c......so wasn't concerned about that system even though I had called and told him about the a/c not working."

FAQs for air conditioning projects in Maynard, 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.
