"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."

"We had a central air conditioning unit replaced. Chris was quick to respond via text message. He arrived exactly at the time he said he would, completed the job in less time than expected, ensured the unit was functioning properly before he left. He additionally offered tips and tricks for yearly maintenance on the unit. He was friendly, courteous, and reliable. We would definitely recommend him in the future."

"In the heat of the summer, our air conditioning shut down. I was worried that I was going to have to spend several thousand dollars to replace it. G & C came out to diagnose the issue and had it solved within an hour. They educated me about Maintainence so that this doesn’t happen again. Very happy with the service and professionalism. I will definitely be using them again!"

"8-26-21 We highly recommend Pro H&C for installation of a ductless cooling system. Sean Pike (owner) was thorough in explaining the product we selected (Fujitsu), and gave us the most reasonable estimate for installation (we had no additional costs added to the final bill). The installation was done in record time considering 1) the demand for installation because of heat waves this summer, and 2) availability of the product. Workers installed and adjusted the unit in just a few hours, and cleaned up the site thoroughly. We were highly satisfied and want to acknowledge his professionalism and standards for business practice."

"H L Bowman is by far one of the best service companies that I have dealt with. I got a call that the technician was on the way to my house. George showed up and got right to work. Found my problem and explained to me the best way to fix my issue. They did not try to sell me on any pricier fixes. George showed me what he could offer and explained what would be my best option. He was knowledgeable, informative, and explained everything so that I would understand what was going on. I am definitely going to be using them for all my heating and air conditioning needs. Top notch company. Would recommend to anyone needing this kind of help."

"Armus Mechanical is top notch! Our AC stopped working during this heatwave and they were at our home in under 2 hours. We have a medically fragile child that cannot tolerate heat and humidity, so we are beyond grateful for their services. They personally went out of their way to ensure our condenser could be replaced. Very polite, very honest and most professional. I'm not one to write reviews, but Armus Mechanical deserves this. We absolutely 100% recommend them!"

"Due to the pandemic it took a while for the park to come in, but after the park came in they were able to fix it the same day. They were terrific and very helpful. They provided portable AC units during the time when our AC was down. This was very good of the company to do."

FAQs for air conditioning projects in Norton, 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.
