Heat Pump Replacement in Pennsylvania
You Need a New Heat Pump. Let Haller Make It Happen.
When your heat pump has stopped doing its job, you do not have time to wait on the wrong company. A failing heat pump does not just cost you comfort. In January, when temperatures in the Lehigh Valley drop into the low 20s, it costs you heat. In July, when humidity pushes the feels-like temperature well past the thermometer, it costs you the ability to make your home livable.
Haller’s team is ready to assess your situation, recommend the right replacement, and get it installed fast. Contact us to schedule your heat pump replacement consultation today!

How to Schedule Your Heat Pump Replacement
Scheduling your heat pump replacement with Haller is straightforward and designed around your convenience.
We keep the process clear and direct so you can move from your current situation to a working system without unnecessary delays.
Call us or reach out online and our staff will gather details about your current system, including its age, how it has been performing, and whether it has needed recent repairs. We will get your replacement 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 comfort specialist visits your home to assess the existing heat pump and measure what your home actually needs. For heat pumps specifically, this means evaluating your home’s insulation, square footage, and duct condition alongside the existing equipment, because a heat pump that is sized wrong for the home it is heating and cooling in Pennsylvania’s four-season climate will underperform from day one.
We walk you through replacement options, including efficiency ratings, cold-climate performance specs, and whether a standard or cold-climate heat pump makes sense for your home’s location and layout. You will receive upfront pricing and clear explanations. There is no pressure to decide on the spot.
Our NATE-certified technicians remove the old system and install your new heat pump with a focus on safety and precision. Before we leave, we run the system through both heating and cooling operation, verify refrigerant charge to manufacturer specifications, confirm proper airflow across the air handler, and test the thermostat and defrost controls. The defrost cycle check matters in Pennsylvania winters, where ice accumulation on the outdoor unit is a normal operating condition a properly installed system has to handle.

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, from the first call to the day your new system is running.
Our technicians are NATE-certified, and Haller is both a BBB Accredited Business and a Carrier Factory Authorized Dealer. That combination means your replacement is handled by technicians trained to manufacturer standards, working with equipment they know inside and out.
Haller has been working in Central and Eastern Pennsylvania since 1981. Four decades of Lehigh Valley winters and summers, Lancaster County cold snaps, and York and Harrisburg heat waves have given our team a deep familiarity with what it takes to size, install, and commission a heat pump that performs through all of it.
A heat pump replacement is a major investment. 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 waiting for a full breakdown to force the decision.
Heat pump 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 during a heat wave in Lancaster, you are not left waiting until morning for someone to call you back.
Every replacement follows strict safety procedures, including proper refrigerant handling, correct electrical connections for the outdoor disconnect and air handler, and thorough post-installation 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.

Frequently Asked Questions
How do I know if I should repair or replace my heat pump?
Age and repair history are the two biggest factors. If your heat pump is under 10 years old and dealing with an isolated issue, a repair usually makes sense. But if the system is 10 to 15 years old, has needed service multiple times in recent seasons, and is struggling to keep up during a Pennsylvania winter or a humid July, the math shifts. A system that is defaulting frequently to backup electric resistance heat in winter is already telling you it cannot do the job on its own. Our technicians will give you a straight answer on which direction makes sense for your specific situation.
How long does a heat pump replacement take?
Most heat pump replacements are completed in a single day. Our team removes the old system, installs and connects the new outdoor unit and air handler, checks refrigerant charge, verifies airflow, and runs full operational testing in both heating and cooling modes before leaving. If the installation involves electrical upgrades to the outdoor disconnect or changes to ductwork, the timeline may vary. We walk you through what to expect before work begins.
What size heat pump does my home need?
Sizing a heat pump correctly requires a load calculation that accounts for your home’s square footage, insulation levels, window placement, ceiling height, and how the existing system has actually been performing through Pennsylvania’s seasons. An undersized unit will fall short on a January night or during a humid August afternoon. An oversized unit will short-cycle, deliver inconsistent temperatures, and wear out faster. Our comfort specialists do not skip this step. Getting it right on the front end is what determines whether your new system performs the way it should five years from now.
Can a new heat pump lower my energy bills?
Yes. Modern heat pumps with variable-speed inverter compressors operate at significantly higher efficiency ratings than systems installed a decade ago. Because heat pumps move heat rather than generate it, they use less electricity than comparable resistance or fossil fuel systems for the same output. In Central and Eastern Pennsylvania, where your equipment runs hard across four distinct seasons, replacing an aging unit with a properly sized, high-efficiency system typically produces a meaningful and consistent reduction in monthly energy costs.
