West Side Oil recently installed a Generac back up generator outside our home. The team did an outstanding job, were customer focused and highly experienced. Since we both work from home, it was important for us to have power. I had a very important meeting scheduled that afternoon and Graham made sure I had the power I needed to run the meeting without a hitch. Thank you, West Side Oil! I highly recommend!

West Side Oil was just at our home replacing several mini splits, condenser, and some third floor work in the attic that we were told couldn’t be fixed by another big name service. WSO sent out 6 trucks worth of people and had the job done in a day. Outstanding service, very fair price, and great quality. I wouldn't use anyone else.

After having our chimney inspected and having a piece of our boiler break, we were quoted with one option, replace the entire chimney and boiler system. We decided to obtain a second opinion and Jordan was quick to come out and discuss several options that may work. After finding a solution which saved us nearly $15k, we decided to continue with West Side Oil. The entire process was discussed and simple to understand. Everyone was friendly and displayed in depth knowledge of every aspect of the system. We ended up getting a Direct Vent boiler installed and our water heater moved and replaced. A large crew spent two days at the house and the level of detail is astonishing! From cleaning up old pipework to ensuring their boots were covered when coming in the house, this crew cares. We can tell this company is about getting the job done right and doing what is best for the costumer. At no point did anyone from West Side attempt to upsell any product or other service. Jordan discussed all options until we figured out what worked best for us and our situation. Turn around time was quick to have the install completed. Couldn't be more excited to use West Side Oil again in the future!

Hi. We've used West Side Oil for almost anything not carpentry or electrical. Two weeks ago I called and asked for information on a gas fireplace. John came out. We talked. He answered all my questions. His brother (Rick or Nick) did the installation. Did not get annoyed at my sitting and watching. It's fascinating Yesterday (4/7) my dear friends and I sat by the fire and shared a bottle of wine. The fire stimulated the most thoughtful sharing in the past years we've known each other. Thank you WSO! Jackie
