If you’ve been considering getting an AC replacement for your old central AC system or installing centralized air in a home that was previously without it, there’s a lot to think about. Today, every manufacturer offers a vast array of products, with something suited for almost every home and situation. Let First Class help you find the right solution for you and your home. If you need a commercial installation, or if you are in need of servicing for a commercial unit, you can rest assured that First Class has the experience, knowledge, and training to get it right the first time around. At First Class, we do AC replacement, installations, and AC repair for all makes, models, and types of air conditioning systems. First Class proudly serves the communities in and near Wicomico County and Worcester County.

In addition to AC maintenance and replacement, First Class also provides the following services and products:

Service and installation of all types of AC systems for residential and commercial properties: While we perform AC replacements for both residential and commercial work properties, First Class’ main emphasis is on private, residential homes in local communities.

Duct cleaning and deodorizing: Cleaning out the air ducts in your home can be particularly important if there are harmful substances within them. For instance, the potential presence of bacteria, mold, insects, vermin, and excessive amounts of dirt and debris are cause for scheduling a duct cleaning to protect the health of everyone inside your home.

Whole-house filtration: Not only can whole house filtration systems be relatively simple to install, but they also can be of great benefit to the water quality in your home. Whole house filtration systems remove contaminants from industrial sources and environmental pollution through a filter connected to the home’s main water line, helping provide clean drinking water for you and your family.

Custom sheet metal: First Class provides customized sheet metal for the systems that we install, ensuring that you receive a product that is customized to your needs.

Preventive maintenance agreements: Scheduling preventive maintenance can often save you loads in the long run. By performing regular check-ups on your home’s systems, we can spot potential problems before they grow into greater, more expensive problems. Indeed, identifying and resolving a minor issue in your AC system is much easier than opting for a complete AC replacement down the road.

UV germicidal lights: Ultraviolet germicidal irradiation, or UVGI, is a disinfection method that kills or inactivates microorganisms using UV light. UV germicidal lights are routinely utilized in spaces requiring disinfection from harmful bacteria and germs.

Extended warranties: First Class offers extended warranties on our services and products.

We also service the following systems:

First Class is your local source for professional, high-quality services. We are proud to serve the communities of Wicomico County, Worcester County, and their surrounding areas.
