Dear Valued Customer,

I founded DeMarco Mechanical in 2012, propelled by a desire to reshape the industry landscape that I had become all too familiar with. Previously, I was a part of a larger corporation, where I witnessed first-hand the deceptive practices and lack of genuine service that often left customers feeling trapped and underserved.

Having experienced the high-pressure sales tactics and subpar work quality, I decided it was time for a change. I envisaged a company that prioritized customer needs, offering the best options, competitive prices, and exceptional service. I believed in the power of personal touch, something that was missing in the impersonal dealings with larger corporations where customers rarely interacted with the same representative twice.

At DeMarco Mechanical, we value accountability and trust. We believe in the adage, "Do what you love, and you'll never work a day in your life." This has been our guiding principle, and it's why we've been able to maintain our passion for what we do.

Our mission is to engineer systems of the highest quality and energy efficiency. We strive to save our customers money while ensuring their utmost comfort for the longest possible duration. We treat our customers as family, standing behind every product and guaranteeing top-quality workmanship.

We are a team of seasoned professionals with a combined 60 years of experience in the industry. We offer both commercial and residential services, specializing in the installation and service of all heating, cooling, and indoor air quality products. Our team undergoes continuous training to stay abreast of all the latest products and technologies.

At DeMarco Mechanical, we believe in giving our customers a wide range of options. Whether it's furnaces, water heaters, boilers, heat pumps, or air conditioning systems, we partner with a broad spectrum of distributors. This ensures our customers have an array of options and price points to choose from, allowing them to select the best fit for their needs and budget.

We don't dictate what you need; instead, we listen to what you want. At DeMarco Mechanical, we are committed to taking care of you.

At your service,

Adrian DeMarco, Owner/Operator
