How to Schedule Your Water Heater Replacement

Scheduling your water heater replacement with Haller is straightforward and designed around your convenience.

We keep the process clear and direct so you can move from a failing system to reliable hot water without unnecessary delays.

Call us or reach out online and our staff will gather details about your current system, including its age, fuel type, tank size, and what you have been experiencing. We will get your consultation on the calendar at a time that works for you, whether you are in Allentown, Lancaster, York, or anywhere across our service area.

An experienced technician visits your home to assess the existing water heater and evaluate what your household actually needs. For water heater replacement, this means reviewing the current tank size, fuel source, venting, and supply connections alongside your household size and daily hot water demand, because a unit sized wrong for the home it serves will underperform from day one.

We walk you through replacement options, including tank and tankless systems, gas and electric configurations, and efficiency ratings. You will receive upfront pricing and clear explanations. There is no pressure to decide on the spot.

Our licensed technicians remove the old system and install your new water heater with a focus on safety and precision. Before we leave, we test the system under operating conditions, verify temperature and pressure relief valve function, check supply and gas or electrical connections for proper operation, and confirm the unit is venting correctly. A water heater replacement is only finished when every connection has been verified under load.

Benefits of Water Heater Replacement

If your current system is aging or underperforming, a new water heater eliminates the frustration of recurring problems and delivers reliable hot water from day one.

Modern water heaters bear little resemblance to the tanks installed a decade or more ago. Higher efficiency ratings, better insulation, and improved safety controls make today’s units genuinely better at the work a Central and Eastern Pennsylvania household demands of them year-round.

Modern high-efficiency water heaters use less energy to deliver the same supply of hot water. Tankless units heat on demand rather than maintaining a standing tank at temperature, and newer high-efficiency tank models insulate better and lose less heat to standby. In a climate where winter cold-water supply temperatures drop and the heater has to work harder through December, January, and February, that efficiency difference shows up in your utility bills every month.

An aging water heater is more likely to fail at the worst possible time, and a tank that has been operating past its useful life is rarely delivering steady performance in the meantime. A new system sized and installed correctly provides consistent hot water without the pattern of declining supply and reactive repairs that come with a failing unit.

If your household has outgrown your current system, running out of hot water becomes a regular frustration. A properly sized replacement matched to your household’s actual usage, whether a larger tank or an appropriately sized tankless unit, eliminates the morning shower shortages and the wait for recovery between loads.

Older water heaters can develop corrosion in the tank, failing pressure relief valves, and compromised gas connections or electrical components. A new system is built with modern safety controls and installed to current codes, which matters in older homes across Allentown, Bethlehem, and Lancaster where the original water heater installation may have predated current safety standards.

Every replacement follows strict safety procedures for supply connections, gas or electrical setup, proper venting, and pressure relief valve testing. We do not consider the job finished until the system has been fully verified under operating conditions.

We keep you informed at every step. You will know what we recommend and why, what the work involves, and what it costs before we begin. No surprises on installation day and no pressure before you decide.

Inspected and will replace heating system.
Thorough, helpful, and efficient.
A/C stopped working on a hot day and the prompt service sold me, had a tech at my house a few hours after calling, a simple fix and money well spent
Very prompt, efficient, and the repaired device is working perfectly.
Joshua came out for a electrical inspection on our initial contract. He was all business and knocked it out in around 30 minutes. Nice guy…very professional
Haller diagnosed the issue with my whole-house water filtration system quickly. It was repaired quickly as well. Friendly service person who explained the issues and solution to me. I already had their service plan for one hvac system, so I converted to a whole home plan to cover the water and upstairs hvac as well.
Systems check up – did a great job very efficiently once arrived. Was a little Kate due to heat wave related emergencies!
Jesse is extremely knowledgeable. He diagnosed the problem with my AC that others had missed.
We purchased our HVAC system from Haller and also established a service contract. Today, Haller sent Christian to service our unit. He was right on time and quickly performed the checkup. These guys do a good job!
Jesse was personable and professional! More than willing to answer questions and informative during the entire visit!
The Haller representative arrived punctually, and completed the inspection of our air conditioning system in a timely fashion. He also took the time to describe what he did, and the functionality of said system. He completed all of this in a very friendly and professional manor.
My experience today was great.my technician was prompt, courteous, thorough and extremely professional. I'd certainly recommend.
Ron was excellent
These guys came out same day and did an excellent job. Customer service and workmanship is great. I love how they have 24/7 service. Would recommend them to anyone.
Excellent service!
Micheal came put and was GREAT! They sent him in a timely manner

Phil was very friendly and even enjoyed our two dogs and gave them a lot of love. Work was done effectively both inside and outside.
Gabe from Haller Enterprises arrived promptly when scheduled. He listened carefully to my questions/concerns and then made an honest effort to find answers/solutions. Although no immediate resolution to the main issue was found, Gabe promised to continue his search on his own and contact me promptly when he had success.
In an out very professional
Don Humenik was our technician. He came with another technician, I think his name was Larry though did not get a last name. I could not ask for a more professional, helpful and friendly experience. We just moved into our house which had one prepaid maintenance visit left from the previous owners. They honored that last maintenance check and so there was no fee to us. That says a lot about how they do business. Because of that, and reinforced by Don and Larry, I signed onto their yearly maintenance agreement. I feel like I finally have a trustworthy, competent, and fairly priced company to work with. Other companies I’ve dealt with in the past have hit one or two of those, maybe good to work with but really expensive. I feel like Haller hits all the marks.
Gabe is the best plumber❣️
Mark was great, had a new toilet and a hot water tank installed,guy know what he was doing Definitely he is a keeper Thanks Mark

Time to Replace Your Water Heater? Look for These Signs

Knowing when your water heater is failing can help you get ahead of a sudden breakdown and the disruption that comes with it.

When repair costs keep adding up, replacing the unit is the smarter financial call. A water heater that has needed service multiple times in a single year is in a different category than one dealing with an isolated issue, and continuing to patch it is usually a gamble that does not pay off. 

An unexplained jump in your monthly utility costs often points to a water heater working harder than it should to maintain temperature. In Central and Eastern Pennsylvania, where winter cold-water supply temperatures drop and the unit is running harder from December through February, an inefficient water heater does not hide that decline in your bills for long.

Visible rust on the tank or discolored hot water is a sign of internal corrosion. Once the tank itself starts to deteriorate, the only safe option is replacement. A corroded tank is a leak waiting to happen, and a tank leak in a utility closet or basement across a Lancaster or Harrisburg home can cause significant water damage before it is noticed.

Traditional tank water heaters typically last 8 to 12 years, and tankless units last 15 to 20 years with proper maintenance. If your system is in or past that range and is also showing efficiency or supply problems, replacement is worth a serious conversation. Our technicians will give you a straight read on where your system stands.

Frequently Asked Questions

How do I know if I should repair or replace my water heater?

Age and repair history are the two biggest factors. If your water heater is under 8 years old and the issue is isolated, a repair usually makes sense. But if the tank is 8 to 12 years old, showing rust or corrosion, leaking, or has needed service multiple times recently, replacement is the more honest answer. A tankless unit that is 15 to 20 years old is in a similar position. In a region where winter demand adds real stress to an already aging unit, continuing to repair a system on borrowed time usually costs more than replacing it would. Our technicians will tell you what they find and give you a straight recommendation.

How long does a water heater replacement take?

Most water heater replacements are completed in a single visit, typically a few hours for a like-for-like tank replacement. Tankless installations, fuel source changes, or work that requires venting or electrical modifications may take longer. We walk you through the expected timeline before work begins and update you immediately if anything changes the scope.

What types of water heaters do you install?

Haller installs traditional tank water heaters, tankless units, gas and electric models, and high-efficiency hybrid systems. Our technicians walk you through the options based on your household size, hot water demand patterns, existing fuel source, and venting configuration so the replacement is matched to your home rather than defaulting to whatever is simplest to install.

Can a new water heater lower my energy bills?

Yes. Modern high-efficiency water heaters use less energy to deliver the same supply of hot water, and tankless systems eliminate the standby losses that come with maintaining a full tank at temperature around the clock. In Central and Eastern Pennsylvania, where winter supply temperatures drop and the heater runs harder for months, replacing an aging unit with a properly sized, high-efficiency system typically produces a meaningful and consistent reduction in monthly utility costs.
