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.


Why Homeowners Trust Haller for Water Heater Replacement

Replacing your water heater is a significant decision, and you want the right team handling it.

Haller has earned the trust of homeowners across Central and Eastern Pennsylvania through decades of dependable work and a process that keeps you informed at every step.

Every water heater replacement is performed by Haller’s licensed plumbers and technicians, not subcontractors. Our team understands the full scope of what replacement involves, from supply connections and venting to pressure relief and fuel source setup.

Haller has been working in Central and Eastern Pennsylvania since 1981. Four decades across the Lehigh Valley, Lancaster County, York, and Harrisburg have given our team a familiarity with the plumbing configurations, venting setups, and code requirements found in homes throughout our service area.

A new water heater is often an unplanned expense. Haller offers flexible financing for qualified homeowners so you can move forward with the right system now and manage the cost over time rather than delaying a replacement that is already causing problems.

Water heater failures do not follow a schedule. Our team is available around the clock, so if your system goes down on a January night in Bethlehem or over a weekend in Lancaster, you are not left waiting until business hours to reach someone.

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.

On time, courteous, efficient. Explained everything he did and what my need done in the future. Great experience with Technician and Haller.
Excellent experience with Shane Keifer on water heater installation. In addition a shout out to Amanda for helping get us booked in a very timely and friendly manner.
Christopher is wonderful and came out quickly . He is very professional and friendly. He took care of my central air and resealed the unit in the house. Closed the vents that are not being used to keep the cold air where I needed it. I would ask for Christoper the next time I had an issue.
Haller is best.
The technician, Adam, was excellent. He explained what the problems were, and showed me the problems on my outdoor fan. He was very patient and polite. I am hard of hearing, so he spoke louder. He fixed everything, and thought of solutions that had not been mentioned to me before – like using a 2" filter instead of a 1" filter to possibly cut down on filter changes (since I cannot change them myself). He also explained how the $24/month plan worked, and set me up for that when I decided to go with it. He answered all my questions. Adam is an excellent Haller employee.
Prompt competent, courteous service
Tech Nevin top notch w/ customer service. Extremely thorough.
Adam B was really amazing to have service my AC unit. He explained things thoroughly and completed everything in a timely fashion. Future services will request him.
Excellent service
Service tech, Phil R. arrived as scheduled, diagnosed the problem quickly and replaced the part on the spot. Thank you Phil for your professionalism and your kind, personable service.
He did an excellent job. ๐Ÿ‘ He is very friendly and kind.
My air conditioner was repaired by Neffsville, but it failed again in just over a month. When it stopped working, I was told it would be four days before they could come back out (itโ€™s 101 degree outside!).

I called Haller Enterprises instead, and they had a technician at my home within 24 hours. Jesse B. was knowledgeable, professional, and took the time to explain the issue and the repair. He diagnosed the problem quickly and completed the repair efficiently.

The difference in responsiveness and overall service was night and day. Based on my experience, I highly recommend Haller Enterprises for your HVAC needs. Thank you, Jesse, and the Haller team, for taking great care of us!
Adam B. came out on an extremely hot day and got the air fixed up and running well as soon as they got my call. He was very polite and friendly and explained everything he needed to do. I would highly recommend the company.
Very professional and tells you exactly what is going on. Highly recommend.
Very courteous and explained what was going on very well.
Thank you for the prompt and excellent service. Jesse was quick to figure out the issues with our ac, clearly explained the problems, and had us up and running again just in time for the heat wave.
Hands down Heller enterprises is one of the best HVAC and all around utility companies out there. Their text and appointment system is top notch. When there are delays they let me know immediately unlike other places that keep you hanging out with no word on what's happening. Technicians are sharp, polite always cover their feet with wraps to protect floors and they really know their stuff.
The technician Nicholas showed up on time as all Haller technicians do! We needed a leak fixed under our kitchen sink and a new faucet installed. The leak was coming from the garbage disposal and asked him if it could be taken out and replace just with plumbing for that side of the sink. He gave me great prices and performed the work in about three hours and was very thorough and cleaned up all the way out to the front door.
Vincent replace our water heater with a tankless one. He is a extremely polite gentleman and explained all things very well. He work long and hard and did a couple extra jobs while here. I would not hesitate to ask for him for anything else needed. Thank You Vincent
Nevin was courteous, professional and got right to work. Haller's employees always are. Nevin is the kind of employee who relates well to Haller's cusomers..
Update 1/2026: I continue to be impressed with Haller and their professionalism and capability. They take the time to explain what's going on and why something should or shouldn't be replaced. The One Call Club continually pays for itself every year!
We have had our system (installed by Haller) for a few years now and use the annual maintenance contract. The last three visits from Haller have been by the same gentleman and he's been absolutely fantastic to work with. He has taken the time to explain options, why something should or shouldn't be addressed immediately and has answered every single question I've had about our system. I'm curious about mechanicals and ask a LOT of questions so it takes a little to get through the answer sometimes. They have always been professional and respectful of my home and cleaned up after they were completed their work. I have recommended Haller to several of my family and friends because its rare that a company is always this easy to work and deal with. I'm going to be a long term customer for sure and am happy I decided to go with Haller for my HVAC installation. Thanks for the awesome experience!!
Experience in 2026 for electrical:
Haller came out and helped me with an electrical issue I had. They came in the evening, patiently described my issue and helped me understand my electrical box. I appreciate the help Jason B. Gave us!

This is an experience for Haller in summer of 2020:
I have a heat pump. It sucks and blows, I know, Iโ€™ve heard the jokes.

But we had an issue recently where our heat worked but our AC only blew hot air. Steve Wakefield, one of the techs from Haller, came out to see what the problem was. He spent several hours with me helping me understand the issue and informed me that the best option would be to replace the unit.

One thing I need to mention โ€” this was a second opinion. The first HVAC company told me that it was busted and the only option was a full install, so I was quoted for a price between 8k – 10k for a heat pump install. Normally a fullInstall would be necessary, but Steve, who provided me with my second opinion, was able to call a supplier right at my house and confirm that they had my outdoor unit in stock and it was compatible with the basement unit.

I then got a quote for a full install just in case; they did everything virtually due to COVID, but it was so seamless. The full install option would be $600 less than the competitor with additional services included!

I have been amazed by Hallerโ€™s service and Steveโ€™s desire to really go the extra mile to help me understand my decision.
He was on time,he let me know exactly what he was doing. He'd showed me what the problem was and what could happen. He was very thoughtful and informative and of course very friendly. Yes, I would recommend him to my home ๐Ÿก. That's why I like having Haller Enterprise for my home needs.
Would like to give positive comment to Jessee and Austin- your two technicians who did a great job on problem-solving our AC unit recently
Ken was excellent including his explanations!

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.
