If it is 2 am and your air conditioner just broke, then Hutchinson is here to help. Our company has trained Customer Service Representatives waiting to take your call, with technicians ready to fix your air conditioner 24/7. Whether you are in Gloucester County NJ or Delaware County PA, our fully-stocked repair vehicles contain all of the parts we need to get you cool again; TODAY! If your air conditioner has seen better days and you are ready for an upgrade to a new system, then you can trust Hutchinson’s trained team of consultants to take the time to study your home’s cooling needs and your personal preferences to find the perfect air conditioner for you and your family. In most cases Hutchinson can install your new air conditioner the next day. If not, Hutchinson can offer either window air conditioners or ‘rescue’ units, this way you never have to spend a restless night because of your broken air conditioning system.

"Photo of Hutchinson - Air Conditioning, Plumbing & Heating Hutchinson - Air Conditioning, Plumbing & Heating Hutchinson installed my high efficiency furnace, a/c unit and hot water heater about 10 years ago. i have had an annual service contract with them since then. They come out every 6 months for routine checks so no other company has touched the equipment since it was installed. at the last service check a few weeks ago the technician told me that the seal around the flue pipe wasn't proper and it was leaking. he showed me a picture of a red sealant around the joint that was pvc pipe. he quoted me a price of $500 to repair it that i agreed to. it took him about 20 minutes to replace a 6 inch piece of pvc pipe. over the next week the amount that i paid wasn't sitting right with me for what had to be done especially since Hutchinson had done the install and therefore they didn't do it right the first time. I called them last week and explained all of the above and asked for a call back that never happened. from dealing with them thru the years i think their techs are incentivized to sell products or expensive repairs. they tried many times to install an ultraviolet air cleaner even though i already have a carrier air cleaner. They are Hutchinson in name only. I looked them up and they are owned by a private equity company that seems to specialize in buying family owned plumbing and hvac businesses. So buyer beware before you let them in your house. as for the hot water install the young plumber used a piece of scrap pipe for the hot water return. fortunately i went to the basement a few hours later and it was leaking because it wasn't soldered correctly. I turned off the water supply and the on call experienced plumber had to come out that evening and redo it and took back the scrap pipe to show his supervisor. other issues with Hutchinson include the time one of their technicians foot went through the attic floor and put a hole in the 2nd floor ceiling. Accidents happen and i was glad he wasn't injured. i contacted Hutchinson and they agreed to cover the cost of the repair. I got a quote and sent it to them and they approved it and i paid the contractor to do it. The problem was getting them to pay me back. They are strictly COD when they come out, but it took many many calls to get them to pay me. Either they were in a meeting or gone for the day and even thought i left messages it took at least 6 or more tries to get them to pay me when they realized i wasn't going away. then there was the issue with the pressure booster we have for our sprinkler system. it started to leak and was still under warranty. Hutchinson took it out and said they would take care of sending it back to the company for a replacement. I called a few times over the next several months and couldn't get an answer as to the status of the replacement. as a result i couldn't open my sprinkler system for the season and the plants and grass were not looking good. Finally i called the Slimer company myself to check on the status and Hutchinson had never sent it back to them. After that both Slimer and myself had to make multiple calls to Hutchinson to find out where it was. In the meantime the Slimer company was kind enough to send out a replacement."

"A Raving Review for Green Mechanical LLC! If you’re looking for the absolute best HVAC service around, look no further than Green Mechanical LLC! This company is truly a gem, and I couldn’t be more thrilled with the incredible service they provided. My heater had been misdiagnosed by another company, leaving my family and me in the cold—literally! Thankfully, I called Green Mechanical LLC, and they completely turned things around. From the moment I called, I knew I was in good hands. Devin Green, the owner himself, came to my house to personally assess the issue. This level of dedication and care is something you just don’t see every day! Devin’s professionalism, deep expertise, and genuine commitment to solving the problem made all the difference. He didn’t just slap on a temporary fix or rush through the job—he made sure to thoroughly diagnose the issue and explain every step of the process to me. A huge shoutout to Jacob and G, who also worked on my system. They were punctual, knowledgeable, and incredibly respectful of my home. Their teamwork and attention to detail were top-notch, and it was clear they take immense pride in their work. Thanks to Devin, Jacob, and G, my heater is now working perfectly, and my family can finally enjoy a warm, comfortable home again! I also want to emphasize how important it is to support small businesses like Green Mechanical LLC. These are the companies that truly care about their customers and their communities. Devin and his team are local experts who go above and beyond to deliver top-notch service, and they deserve every bit of your trust and business. If you need HVAC services—whether it’s a repair, installation, or just regular maintenance—do yourself a favor and call Green Mechanical LLC. Their commitment to excellence, fair pricing, and outstanding customer service make them a company you’ll want to recommend to everyone you know. Thank you, Devin, Jacob, and G, for your amazing work and dedication. You’ve earned a lifelong customer! 🌟"

Central a/c service or repairs FAQs

Yes, a once-a-year tune-up keeps the system efficient and helps it last longer. During the visit, a technician cleans coils, checks electrical connections, and swaps or cleans the filter. Catching small issues now stops bigger, pricier failures later, so that a quick appointment saves money and stress over the life of the unit.

Changing your AC filter every 30 days is necessary to maintain optimal performance and high indoor air quality. Regular filter replacement prevents dust buildup, ensures efficient airflow, and protects the system from stress that could lead to costly repairs. This disciplined maintenance routine not only boosts energy efficiency but also prolongs the lifespan of your unit by safeguarding its critical components.

An HVAC service plan is worth the cost, especially if you forget to schedule maintenance on your own. A service plan locks in yearly (or twice-yearly) visits, allowing a professional to identify small problems early, clean key components, and maintain energy efficiency. Many plans also include minor repairs or priority scheduling, which can pay for themselves if an unexpected issue pops up.

In a pre-season service visit, your technician gives your system a top-to-bottom check before peak season hits. Expect a filter change, thermostat test, condenser-line flush, electrical-connection check, and coil cleaning. They also tighten loose parts and make minor adjustments so the unit fires up without surprises when temperatures swing. That quick tune-up cuts the risk of mid-season breakdowns and keeps energy use in line.
