Tank And Tankless Hot Water

Water Heater Services in Lancaster, PA - Tank & Tankless Repair, Installation & Maintenance

No hot water, not enough of it, or a tank that has started to leak. Smart Air Heating & Cooling installs and services both tank and tankless water heaters across Lancaster County. Call 223-221-2589.

The Appliance You Notice Only When It Stops

A water heater does its job quietly for years and then fails in one of two ways: it stops making hot water, or it starts putting water on the floor. The second is the one that turns an appliance problem into a building problem, which is why the warning signs in between are worth acting on. Rusty water, a tank that has become noisy, or hot water that runs out sooner than it used to are all telling you something.

Smart Air Heating & Cooling handles the full range of hot water work: repairing what can be repaired, replacing what cannot, and performing the annual service that keeps a unit from aging prematurely. We install Bradford White tank water heaters and Navien tankless systems, and our HIC #PA165573 licensed technicians service both types from other manufacturers as well, with 38 years of combined experience behind the work.

Because we also do gas piping, we can handle installations that need a new or resized gas line rather than subcontracting that part out, which comes up frequently on tankless conversions. We serve Lancaster, Elizabethtown, York and the surrounding communities.

Our Water Heater Services

Same team for tank and tankless, repair and replacement.

Water Heater Repair

No hot water, not enough hot water, water that runs hot and then cold, discolored water, rumbling from the tank, or an error code on a tankless unit. We diagnose thermostats, heating elements, gas valves, igniters, dip tubes and venting rather than defaulting to replacement.

Water Heater Repair Services

Water Heater Installation

Replacements and conversions, sized against how your household actually uses hot water rather than by copying the label on the old unit. We handle removal and disposal, water and gas connections, venting, safety devices, and the permits the work requires.

Water Heater Maintenance

On a tank, that means flushing sediment, checking the anode rod, testing the relief valve and verifying the thermostat. On a tankless unit it means descaling the heat exchanger and cleaning the inlet filter. Both are the difference between a unit that reaches its expected life and one that does not.

Tank or Tankless?

Both are good systems. They suit different households, different basements and different budgets, and the honest answer depends on your situation rather than on which one is newer.

Tank Water Heaters

A storage tank keeps a set volume of water hot and ready. Recovery rate, not just capacity, determines whether you run out, which is why a high-recovery unit can outperform a physically larger one.

Where a tank makes sense:

  • Straightforward like-for-like replacement with no gas or venting changes
  • Lower up-front cost than a tankless conversion
  • Simple to service, and parts are widely available
  • Handles several simultaneous fixtures easily until the tank is depleted

We install Bradford White tank units and service anode rods, sediment build-up and thermostats on tanks of any brand.

Tankless Water Heaters

A tankless unit heats water as it flows, so it does not store anything and does not run out. It also does not spend the night keeping a tank of unused water hot, which is where its efficiency advantage comes from.

Where tankless makes sense:

  • Households that want continuous hot water for long or back-to-back demands
  • Basements and utility rooms where floor space is worth reclaiming
  • Homes where eliminating standby losses matters
  • Situations where the gas supply and venting can support the conversion

We install Navien tankless systems and flush them to keep scale off the heat exchanger, which is the maintenance item that matters most on this type.

Converting from tank to tankless usually involves gas line and venting work, so ask for that to be quoted as part of the job rather than discovered mid-installation. See how we handle installation.

Water Heaters in Lancaster, PA: Frequently Asked Questions

Your Hot Water Questions Answered

It depends where the leak is. Water coming from a fitting, a valve or the relief line is often a repair. Water coming from the body of the tank itself is not, because that means the tank has corroded through and it will only get worse. Shut off the water supply to the unit and call us, since a tank that has begun to fail can go from a drip to a flood without warning.

On a tank unit the usual culprits are sediment taking up volume at the bottom of the tank, a broken dip tube letting incoming cold water mix with the hot at the top, or a failing heating element or thermostat. Household demand can also simply have grown. A maintenance visit will identify which of these it is, and sediment is often correctable with a flush.

It is a sacrificial metal rod inside a tank water heater that corrodes so the steel tank does not. Once it is consumed, the tank itself starts to go, which is the point at which a water heater begins its final chapter. Checking and replacing the anode rod is one of the cheapest things you can do to extend a tank's life, and it is part of our maintenance service.

Yes, and skipping it is the most common way people are disappointed by tankless. Minerals in the water deposit as scale on the heat exchanger, which reduces output and eventually causes error codes and shutdowns. Periodic descaling, along with cleaning the inlet screen, keeps the unit performing as designed, and it is normally a condition of the manufacturer warranty.

For some households, clearly. Continuous hot water and reclaimed floor space are real benefits, and there are no standby losses from keeping a tank hot. The considerations are that a conversion normally requires gas line and venting changes, and that flow rate is finite, so heavy simultaneous demand needs to be sized for. We will tell you what your particular house would need before you decide.

Yes. Gas piping is one of our own services, so if a tankless unit needs a larger supply line or a run extended to a new location, the same company that sizes the water heater does that work. That avoids the coordination gap where one contractor installs the appliance and another discovers the gas supply cannot feed it.
