Tankless Water Heater Installation in Falls Church
Careful Tankless Installation Backed by Home Comfort Experience Since 1959
Replacing a storage water heater with a tankless system isn’t a simple appliance swap. Before recommending equipment, we evaluate peak hot water demand, available space, fuel source, utility capacity, venting, and existing connections.
When you work with Richards Heating & Air Conditioning Co., Inc., we explain your options in plain language. You’ll understand the installation requirements, maintenance needs, and potential tradeoffs before deciding whether an on-demand system fits your home.

How We Size an On-Demand System for Your Home
We size equipment around the hot water your household may need at one time. That means calculating both flow rate, or the amount of water passing through each fixture, and temperature rise, the difference between the incoming water temperature and the desired output temperature.
An installation assessment may cover:
- Simultaneous hot water use: Showers, faucets, washing machines, and other appliances that may run at the same time.
- Gas or electrical capacity: Whether the available utility supply can support the selected equipment.
- Venting and combustion air: How a fuel-burning unit receives air and safely exhausts combustion gases.
- Water connections: Pipe condition, connection locations, shutoff access, and drainage needs.
- Equipment placement: Required clearances, service access, and practical use of the available space.
We’ve served Northern Virginia homes since 1959, and that experience informs how we assess the entire comfort system. Our recommendations account for your household needs, existing equipment, available space, and utility costs rather than treating every water heater as a direct replacement.
Workmanship Guided by The Richards Creed
The Richards Creed sets a clear standard for our work: use quality materials, tools, and workmanship, stay current with comfort-conditioning equipment, and don’t consider a job complete until the customer is satisfied. We also protect nearby areas and clean the work area thoroughly after installation.
Our company provides residential heating, cooling, indoor air quality, and water heater services. For our customers’ protection, we carry more than $3,000,000 in insurance coverage.
What to Expect During Installation
After assessing your home and discussing equipment options, we outline the work plan before installation begins. The scope depends on the existing heater, selected system, fuel source, and any changes required for water, gas, electrical, venting, or condensate connections.
Our installation process includes:
- Preparing the work area: We protect nearby surfaces and confirm access to the installation location.
- Positioning the equipment: We disconnect or remove the existing heater as applicable, then place the new unit with appropriate service clearances.
- Completing connections: We connect the water supply, fuel or electrical service, and required venting.
- Checking operation: We inspect the connections and test system temperature, flow, and basic operation.
- Reviewing the system: We explain the controls, shutoff locations, normal indicators, and maintenance expectations.
Fuel, Venting, & Inspection Requirements
The City of Falls Church requires an on-site fuel-gas vent certification when a fuel-burning appliance is installed or replaced in an existing R-5 occupancy, a classification that generally includes one- and two-family homes. This certification verifies the sizing and function of an attached vent or chimney system for inspection.
The project configuration determines which Virginia fuel-gas, plumbing, electrical, manufacturer, and local inspection requirements apply. Older equipment, limited utility space, an undersized gas line, or a constrained vent path may require additional planning before work can proceed.
Planning for Tankless System Maintenance
Maintenance needs vary with water conditions, system design, usage, and manufacturer instructions. A unit may require periodic flushing or descaling to remove mineral deposits from the heat exchanger. We explain these expectations while reviewing your options and plan for accessible shutoffs, adequate service clearance, and practical filter access.
Comparing Tankless & Storage Water Heaters
A tankless system heats water as needed instead of maintaining a stored supply. It can provide continuous hot water while demand remains within its rated capacity, but it isn’t the right choice for every household.
Factors to compare include:
- Hot water delivery: A properly selected unit can support extended use, but simultaneous fixtures are still limited by its capacity.
- Equipment footprint: Wall-mounted equipment may use less floor space than a conventional storage tank.
- Installation scope: Gas lines, electrical service, venting, condensate drainage, and water connections may require modifications.
- Energy use: On-demand equipment avoids maintaining a tank of heated water, although actual utility costs vary by household use and system type.
- Maintenance: Periodic flushing, filter care, and accessible service space may be necessary to address mineral buildup and follow manufacturer instructions.

Frequently Asked Questions
How Long Will My Tankless Installation Take
A typical installation usually fits within a single day, although more complex homes may take longer. The timing depends on your existing gas or electrical setup, venting path, and how easily we can access the old heater. We discuss timing with you up front so you can plan.
Can My Current Gas Or Electrical Setup Handle Tankless
Many homes can support a tankless unit, but we confirm this first. Our team reviews your gas line size, electrical capacity, and panel space, then recommends equipment that matches what your home can safely provide. If upgrades are advisable, we explain what is involved so you can decide.
Will Your Team Keep My Home Clean During The Job
We make cleanliness a priority. Our technicians use protective measures where needed, carefully remove the old heater, and clean up debris before leaving. The Richards Creed calls for us to leave your home as we found it, and we work to meet that standard on every installation.
How Much Maintenance Does A Tankless Water Heater Need
Tankless systems do require periodic care to keep them running well. Depending on water quality and usage, this often includes flushing the unit and checking filters or screens. During installation, we explain simple maintenance steps and can discuss service visits to help you keep your system in good shape.
How Do You Price A Tankless Installation
Pricing reflects the specific equipment, the complexity of your existing setup, and any changes needed for gas, electrical, or venting. We work to provide clear, honest information about these factors before work begins. Our goal is to offer fair pricing with no surprises, in line with our long-standing values.
