You guys did a great job and were immaculate! Thank you for that. Unfortunately, we cannot keep the sign in the yard. We are not permitted to do so.
I signed up for annual maintenance service for our HVAC/Water Heater/Water Softener plus Dryer Vent Cleaning. The process was simple and quick. I was contacted soon after to schedule visits and was able to have techs come the same day. Both guys were professional, friendly, explained what they were going to do and any issues/suggestions they had. The work was done well and we are very pleased.
Very professional, detailed, excellent service
Iโ€™ve used Haller Ent. several times over the years, and they continue to exceed my expectations every single time. Most recently, they handled a major repair for a broken sewer pipe in my front yardโ€”no small jobโ€”and the entire experience was outstanding from start to finish.
The technicians Moises, Ben, Mike, and Danโ€”were absolutely exceptional. Not only were they highly skilled and efficient, but they also took the time to explain the process, answer my questions, and make sure I felt confident every step of the way. They went above and beyond to make sure I was satisfied.
I have recommend Haller to several people and each one had positive experiences. I won't hesitate to call them again and will continue to recommend them to anyone in need of reliable, high-quality plumbing services.
We had a plumbing inspection. Michael was seethorough and informative and personable. He and his assistant worked very efficiently. We did have a small valve leak to an outside spigot repaired.
The entire process from the sales to the full implementation in Communications was both rapid and very highly professional. I highly recommend Haller for excellence in what they do. Thank you!

Excellent serviceโ€”Nick was courteous, knowledgeable and efficient. He went beyond what he was asked to do.
We just had a service check done on our AC unit. Our technician, Jonathan was very courteous and thorough.
Did an excellent job and fixed the problem in a short time frame. I would
definitely call again for yearly maintenance or any other HVAC issues
Triangle installed our small commercial system in 2016 and we've been experiencing failures nearly every year since. We kept trying to get them to send somebody to root cause the system for the failures, but every time they would just come out and replace the same blown fuse or a wire and send us a bill for ~$1000. We tried communicating our need for a real solution with the main office, but it just sent us to a call center in California. Finally gave up on them and had someone from Haller come out to look at the system, and on the first trip they found multiple errors in the system set up, fixed those, and sent us a bill for about 1/3 the cost. At least the positive here is that we found our new, go to HVAC company, with Haller. Thank you, Hunter!
Customer service contact,In a word Wonderful. Angie is the best. Service Tech Chris who did maintenance professional, knowledgeable and friendly. They enhance the the Company. Kudos to them.
As far as Brayden.i give him a 5 star review..
Nevin did an outstanding job diagnosing and solving a problem with thermostats in our HVAC system. He was patient and professional throughout the service visit.

Heat Pump Repair Services

Has your heat pump stopped working?

Whether your system is making unusual noises, struggling to keep up, or not working at all, Haller’s NATE-certified technicians diagnose the issue and provide reliable, long-lasting repairs across Central and Eastern Pennsylvania.

Low refrigerant levels reduce your system’s ability to heat and cool effectively. We locate and repair leaks, then recharge your system to restore proper performance.

Faulty wiring, capacitors, or relays can cause your heat pump to malfunction or stop working entirely. Our team safely repairs or replaces damaged electrical components to get your system back on track.

A malfunctioning thermostat leads to inconsistent temperatures or system failures. We diagnose control issues and repair or replace thermostats to restore accurate operation.

If your heat pump is icing over or not defrosting properly, it affects efficiency and performance. We repair defrost controls and components to keep your system running smoothly through cold Pennsylvania winters.

Grinding, rattling, or squealing noises usually point to a failing component. We diagnose the source and complete the repair before it turns into a full system failure.

Heat Pump Replacement Services

Haller’s heat pump replacement services make upgrading your home comfort system simple and stress-free.

If your current system is no longer keeping up, our team helps you choose and install a modern, energy-efficient heat pump that delivers reliable performance for years to come.

A failing or outdated heat pump works harder to maintain your desired temperature. Replacing it with a high-efficiency system lowers your monthly energy costs.

If you are noticing uneven temperatures or your system cannot keep up with heating and cooling demands, it may be time for a replacement. A new heat pump restores consistent comfort throughout your home.

Repeated repairs quickly add up and become frustrating. Investing in a new system eliminates ongoing issues and provides dependable performance.

Most heat pumps have a lifespan of 10 to 15 years with proper maintenance. If your system is reaching this age, replacing it improves efficiency, reliability, and overall home comfort.

Rust, corrosion, or damage to the outdoor unit is a sign the system has reached the end of its usable life. A replacement restores both performance and appearance.

Heat Pump Maintenance

Our heat pump maintenance services are designed to keep your system running efficiently, reliably, and safely throughout the year.

Heat pumps accumulate operational hours faster than single-season equipment, which makes regular service more important, not less. Consistent maintenance delivers the following benefits:

A clean, properly charged heat pump runs at its rated efficiency in both heating and cooling mode, which shows up in your monthly utility costs across all four seasons. 

Regular service reduces compressor strain and component wear, adding years to the usable lifespan of the system.

Small issues caught during maintenance do not turn into mid-season failures when the system is under the most demand.

A well-maintained heat pump holds setpoints accurately through the coldest stretches of winter and the hottest weeks of summer.

Professional Heat Pump Installation

Haller provides professional heat pump installation services designed to deliver reliable, energy-efficient comfort for your home.

Whether you are upgrading your current system or installing a heat pump for the first time, our team ensures a seamless process and long-lasting performance.

If your existing HVAC system is nearing the end of its lifespan, installing a new heat pump improves efficiency and reliability. A modern system reduces energy costs while providing more consistent comfort.

Heat pumps are known for their energy-saving capabilities, which makes them a smart choice for homeowners looking to lower utility bills. Upgrading to a high-efficiency system significantly reduces your home’s overall energy usage.

If you are calling for repairs more often, it may be more cost-effective to invest in a new heat pump. A new installation eliminates ongoing issues and provides peace of mind.

Installing a heat pump during new construction or a major renovation allows for optimal system design and efficiency. It is the right opportunity to choose a modern all-in-one heating and cooling solution tailored to your space.

A heat pump handles both heating and cooling from one piece of equipment, which simplifies your home’s comfort system. For many Central and Eastern Pennsylvania homes, that is the right long-term fit.

Heat Pump FAQs

How often should my heat pump be serviced?

Heat pumps should be serviced at least once a year, though twice-yearly maintenance is ideal since they provide both heating and cooling. In Central and Eastern Pennsylvania, where the system runs through four demanding seasons without a meaningful off-season, regular service is what keeps efficiency and reliability where they should be.

How long does a heat pump usually last?

Most heat pumps last between 10 and 15 years with proper maintenance. Year-round operation in this region accumulates hours faster than single-season equipment, so scheduling routine tune-ups and addressing repairs promptly is what gets your system to the upper end of that range.

What are some signs my heat pump needs repair?

Common signs include unusual noises, weak airflow, inconsistent temperatures, or higher energy bills. If you notice any of these issues, schedule a professional inspection before a mid-season failure forces the decision.

Is a heat pump energy efficient?

Yes. Heat pumps transfer heat rather than generate it, which is significantly more efficient than traditional heating systems. In Central and Eastern Pennsylvania’s climate, that efficiency shows up in monthly energy costs across all four seasons, not just one peak season.

Can I finance a new heat pump installation?

Yes, Haller offers flexible financing options for qualified homeowners to make heat pump installation more affordable. Our team can help you explore available plans and choose a solution that fits your budget.
