Water Heater Repair & Installation in Arlington, VA

Repair or Replace? How We Decide

Not every water heater problem means buying a new unit. We look at age, the specific symptom, and repair cost relative to replacement before recommending either.

When Repair Makes Sense

A failed thermocouple, a tripped element, a faulty thermostat, or a stuck pressure relief valve are common, relatively inexpensive fixes on a unit that's otherwise in good shape — especially if it's under about 8 years old.

When Replacement Makes More Sense

Once a tank unit passes the 10-year mark, or if it's leaking from the tank body itself rather than a fitting, repair generally isn't worth it. A leak from the tank means internal corrosion has gone through the metal — no repair reverses that, and the tank is at real risk of a sudden, larger failure.

Tank vs. Tankless: Which Fits Your Arlington Home

Both are solid technologies — the right choice depends more on your home type and hot water habits than on either being objectively superior.

Tank Water Heaters

Lower upfront cost and simpler installation make tanks the default for most single-family homes with basement or utility closet space to spare. They're a safe, well-understood default that's easy to service.

Tankless Water Heaters

Higher upfront cost but a much smaller footprint and effectively endless hot water — a strong fit for Arlington condos and townhomes where mechanical space is tight, or larger households that regularly run out of hot water with a tank system. Tankless units also commonly outlast tank units, though they need periodic descaling given the area's moderately hard water.

What Actually Drives the Decision On-Site

Existing gas line capacity (tankless units need more BTU input than most tanks), venting requirements, and whether it's a like-for-like swap or a full conversion all affect installation cost more than the sticker price of the unit itself. We evaluate this during the quote, not after the job starts.

Sizing a Water Heater Correctly

An undersized unit means cold showers during peak use; an oversized one wastes energy keeping water hot you don't need yet. As a rough guide: 30–40 gallons suits 1–2 people, 40–50 gallons fits 3–4 people, and 50–80 gallons (or a properly sized tankless unit) fits larger households or homes with multiple bathrooms used simultaneously. For tankless systems, sizing is based on flow rate — how many fixtures might realistically run hot water at once, like a shower and a dishwasher together.

Special Considerations for Arlington High-Rises

Water heater decisions look different in a Rosslyn, Ballston, or Crystal City condo than in a single-family home. Many units are compact or tankless specifically because a standard 50-gallon tank doesn't physically fit the allotted utility closet. Condo associations often have specific rules about water heater type, venting, and sometimes even replacement scheduling — worth checking with your HOA before purchasing. Some older high-rise buildings also run domestic hot water through a shared building system rather than individual unit heaters, which changes the entire scope of a repair. We'll help you figure out which setup your building uses before recommending a fix.

What's Included With Installation

Every replacement includes removal and disposal of the old unit, proper venting and connection to code, a pressure relief valve check, and a walkthrough of your new unit's settings and maintenance needs. We pull the required permit as part of the job — not an optional add-on.
