First Class Plumbing - Heating & Air ConditioningHeating and Air Conditioning

First Class Plumbing also has a Residential Heating and Air Conditioning division, dedicated to keeping you comfortable in your home. We are offering American Standard top of the line equipment and or Rudd Equipment.


We are a licensed HVAC contractor serving parts of Maryland, Washington DC, and Northern Virginia. We do furnace and air conditioning repair on any make or model. For new installations, we recommend American Standard or Rudd.

Furnace stopped working? AC on the fritz? We can mobilize at a minute’s notice to respond to emergencies. We work with homeowners throughout the area. We understand that having a regulated temperature is a comfort issue, but for people with certain health conditions, it’s crucial.

To avoid emergencies as much as possible, we recommend a yearly check-up of your heating and air conditioning system. In this way, our HVAC technicians can identify small problems before they turn into big ones.
