The technician arrived on time, knowledgeable and walked me through the entire process. Open communication, no hidden fees, did not fix items that were not broken, honest with issue and pricing. They were here to fix the problem and not to give a sale pitch. I would HIGHLY recommend and will be using them again for yearly maintenance."

N.E.T.R., Inc. is here to help homeowners install the best heating and cooling systems that fits their needs. Since 1989, we've installed heating and cooling systems in Boston and its surrounding areas, tackling tough problems that our clients face. Our goal is to ensure our clients have energy efficient, quiet, reliable systems so they can live their lives to the fullest both at home and at work. Our dedication to our customers' needs is what drives us each and every day. Our approach to temperature control and comfort has helped us become one of the most respected names in heating, cooling, and refrigeration in New England.

"From start to finish, NETR did a fantastic job. I met 3-4 other vendors, and they didn't come close to NETR's responsiveness, professionalism, or timeliness. NETR earned my business before I even got a quote from some of the others. The salesman, Mark, arrived on time, was respectful & attentive to what we needed, explained our options well, and provided a competitive quote before he left my home. NETR also offered a 5-year 0% interest loan for the project (via a relationship with GreenSky). It took only a few days to schedule installation. The installers were prompt, professional, respectful of our property, and did an excellent job installing the electrical components, compressor, branch box, and 5 heads. They did a nice job of consolidating and hiding the lines on the outside of the house. This past year, we've worked with many contractors, some good, some terrible, so I can compare. NETR was one of the best, and I would hire them for my next project in a heartbeat. "

Central a/c service or repairs FAQs

An AC capacitor provides the electrical energy needed to start and run your air conditioner's motors. It stores and releases electricity to keep the compressor and fans running smoothly. Without a functioning capacitor, your AC unit may not start or operate efficiently. If you notice problems with your AC unit, contact a professional to diagnose the problem and see if you need to replace your AC capacitor.

AC capacitors last between five and 15 years, with an average lifespan of ten years. Environmental conditions and system usage can affect their lifespan. Regular maintenance can help extend the life of your capacitor. When your replacement capacitor is installed, be sure to ask your AC technician about best practices for maintenance and ongoing service to keep your unit in good condition for as long as possible.

While you might save between $60 and $200 by replacing the capacitor yourself, it's not recommended unless you have electrical expertise and proper safety equipment. Replacing a capacitor involves risks like electric shock and potential damage to your AC unit. It's safer to hire a certified HVAC technician who ensures safe and accurate installation.

It's safest to have a qualified technician inspect your AC capacitor. If you decide to look at it yourself after turning off all power, you can carefully remove the front panel and check the capacitor for any visible issues. However, handling electrical components carries risks, so professional inspection is recommended.
