"I bought my unit from NETR in 2018. It worked fine until we discovered it wasn't blowing any cold air. I made the big mistake of hiring someone a family friend recommended and they diagnosed it incorrectly and then basically disappeared on me. Anyway, it took a few weeks but they repaired it today and I was impressed with their courtesy and getting the job done very quickly and successfully. I felt like I was being dealt with honestly. Thanks, Jared and Jack. I should mention I paid about $300 for the refrigerant today. I don't know what the final cost will be but probably a bit over $1000."

"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."

"Our AC stopped working on day, of course it was 90 out that day My wife has a medical condition which is made worse by high temps & humidity. I found servicemagic on the internet filled out a simple form when the phone rings its servicemagic honest 10 minutes later we had some one on the phone setting up a service call. The next after noon Mr. Obrien shows up "ON TIME" spends 30 minutes or so working on our unit and its fixed for just $200 We had another repair person come out for the first look, he tested some wires and told us we needed a whole new unit only $1500-$2000. I plan to call again in Sept. for a heater check up before winter hits"

"My central air system went down in the middle of a heat wave and virtually every HVAC repair service that I called told me that they weren t taking new clients and couldn t help me. I contacted Chris through home advisor and he agreed to help me out. He promptly came to my house, identified my problem, and ordered parts. When the parts arrived he immediately came back and installed them and I was up and running. Chris identified and fixed my problem and the entire process took only 2 days. On top of that, the price was more than reasonable and Chris is a super nice guy. I highly recommend Chris because he is a skilled and professional technician."

"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."

FAQs for air conditioning projects in Winthrop, 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.
