AC Unit Options For Your Home

Traditional Central Air: Reliable whole-home cooling through a system of ducts, keeping every room comfortable all summer.

Ductless Mini Splits: Flexible, energy-efficient cooling with individualized comfort for specific rooms or zones.

Traditional central air systems cool the entire home through existing ductwork, making them a great fit for homes with forced-air systems. Ductless mini splits deliver targeted comfort to individual rooms or zones without the need for ducts, offering greater flexibility for additions, older homes, or spaces with unique cooling needs.

Had an oil tank replaced that was long overdue. They made the process smooth and worked with me to get a great price. Allie was very helpful and responsive throughout the quoting and scheduling process. Adam and Jeff came to do the installation and they were also great, friendly, and had the entire job done quickly and clean. Would highly recommend Acorn Oil!

Highly recommended! Our oil tank sprang a leak and after being led around by another company for a week of poor communication and one delay after another, Acorn came out and replaced the tank within 24 hours to get it done before we were hit with a foot and a half of snow. Jeff and Craig were polite and professional and explained the entire process, including getting our fixtures and piping up to code. We've since shifted our routine boiler maintenance over to Acorn because of their reliability and top-notch service.

Acorn Oil recently replaced my 62 year old heating oil tank with a modern double wall tank. They showed up on time, did a great job, cleaned up and were very professional. I would definitely recommend Acorn.

I usually don't write reviews, but had to this time. They replaced my ancient furnace and oil tank, all in one day. So grateful for the quality, professionalism and friendliness of the service I was provided. James, Jeff, Craig and all the team were wonderful. Highly recommend.

They are an exceptional company to work with. We needed to replace our oil tank that had wet spots on the bottom of the tank. They came out right away and assessed the tank as well as gave us some options. They worked with us and we came up with a plan to get the tank replaced. Kyle is very knowledgeable and is a pleasure to work with. The team he had come in to cut up and remove and install the new tank was professional and efficient. They were done in a few hours and were clean. They didn't leave a mess and put everything back to how it was. They did have to move the washer and dryer as well as remove the door and railing but they put them back before they left. As new a new homeowner, they gave us some peace of mind and I am happy to continue to give them our business going forward. Accorn Oil is fair and will be the company we choose to use for our heating needs!

I am thrilled that my husband and I went with Acorn for our oil service. We had a different company that 'came with the house' when we purchased in March. The other company didn't give us many options and were not great at communication. Acorn was recommended to us and definitely did not disappoint! We needed an oil tank replacement, and Kyle and the team came out to check out our situation, took measurements, and laid out all of our options in a very clear and concise way for me (brand new home owner, I know nothing about oil heat!) to understand. They came yesterday to do the install and the team was efficient, clean, and left our property with no damage or mess to deal with. They were incredibly professional and I am very happy to continue to give Acorn our business. Thank you!!!!!

My oil tank started leaking Tuesday afternoon. I called my oil company and got no answer or call back, so I started calling down the list of oil companies. Acorn not only was the only one to answer, but they had some one come out that same day to assess the problem and then tank was replaced on Thursday. Probably 48 hours total from problem located and solved. I still haven't heard from my now old oil company. Acorn Oil is the way to go.

Quick response, thoughtful while working in the house (e.g., cleaning up after repairs), clear communication from the team, and the installation of the oil tank looks right to my untrained eye.
