"Two men, Jerry and Tommy, arrived on the morning of May 19, 2017 to install the system. Tommy dug a hole on one side of the house, poured a concrete foundation in said hole, and also set up metal tubing, which created a stand on which the condenser sits to protect it from runoff. Meanwhile, Jerry was inside, drilling holes through my bedroom and dining room interior and then exterior walls for the refrigerant pipes which run from the condenser to the air handlers. He mounted each air handler high up on the wall. There was also electrical work performed to connect the units to the main panel in the basement. The whole job took several hours. Both men worked quickly and efficiently. At the close of it, Jerry presented me with my remotes and instructions, and showed me the basics. I used the system for the first time just a couple of nights after installation. The first night (it was the start of a heat wave) the air from the system was cool-ish - tolerable, but not quite as comfortable as I'd hoped - but I was still uncertain about the controls so I didn't tab down the temperature. The second night I did tab down the temperature, and that's when I found out that, though the fans and vanes in both air handlers worked, the cooling mechanisms did not. Considering the amount of money I'd just spent i was more than a little upset. Visions of law suits danced in my overheated head that night. I called the next morning. Jerry came out that day and diagnosed the problem (something to do with the solenoids, or maybe it was the thermistors). In any case, he did fix it, and this time, it worked as designed, and has done so ever since. I should add that NETR offers a service contract. Despite the added expense - for me, 234.99 a year for 3 years (the annual rate is fixed for that period, plus I get a 5% discount) - it makes total sense to have this complex system undergo periodic maintenance. I will pay the total at the time of the first inspection, in 2018."

"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."

"Punctual, professional, and repaired/properly installed a heating/air conditioning unit that had been previously installed incorrectly. However, we did not call around for pricing. After a poor experience with a lower cost service, we just wanted the job done right. We would definitely call them again."

FAQs for air conditioning projects in South Lancaster, 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.
