About Me Hi, I’m Heather! I’ve been a professional cleaner for over 10 years, and I truly love what I do. Cleaning isn’t just a job for me—it’s something I take pride in. I find it therapeutic and rewarding to transform a space and leave it fresh, organized, and welcoming. My clients appreciate my reliability, attention to detail, and the care I put into every home I clean. I treat every space as if it were my own, and I always aim to go above and beyond expectations. Whether it’s a deep clean or regular upkeep, I believe a clean home brings peace of mind. Fun Fact: I actually find cleaning relaxing! There’s something satisfying about seeing instant results and knowing I’ve helped make someone’s day a little easier.

Central Vacs Unlimited is a family-owned business which was started in 1974 and has been under the current ownership since 1997. We are one of the largest dealers of central vacuums and intercoms in the mid-Atlantic area. The showroom is stocked with many of our products enabling customers to "test drive" them before they are installed. We do not subcontract our work. Our own employees do the installations and make service calls. We are not aligned with a single manufacturer like many other companies. In fact, we offer more brands and product choices than virtually any other company. This enables us to provide products which meet the exact needs of our customers. Free estimates are provided on installation of new systems. We offer free technical support over the phone. Often, we help customers troubleshoot and repair systems on their own. Our courteous staff is available six days a week to greet our customers. We welcome an opportunity to work with you.
