Haller has updated some of their communications. I received confirmation of my online booking. A text with picture of who was coming. Another text to state employee was on the way. If you are looking out for safety, I can't recommend a better company. I have been using Haller services for about 10 years. Haller has been great about everything. I know some of you are going to say expensive. I have never needed a second visit for anything that they fixed. Done once and done right. Thank you!

Our church in Downingtown recently constructed a memorial garden. This was a fairly diverse project that required masonry, landscaping, and electrical crafts. We selected Hallar for the electrical portion of the project which required them to work closely with the mason in order to ensure a coordinated installation. Things went very well and the end result was a very successful project. Hallar installed the lights and a timer system which make for a very subdued and quiet setting in the evenings. In addition, during excavation for the masonry walls, our water service pipe was damaged. Because Hallar’s is a multi-craft company they were able to make the necessary repairs to the water line without any disruption to the project schedule at a very reasonable price. We would recommend Hallar’s for any project which requires electrical, plumbing, or HVAC expertise. They are proven to be cooperative, timely and highly skilled.

Wesley arrived at the designated time frame the appointment was made. He answered all are questions and addressed the concerns we had. The HVAC inside system is located in the attic and is not easily accessible. Wesley brought a ladder and was able to get the job done. He was very polite and honest. He also made sure to wear foot coverings while inside the house. A job well done!

We had been having air conditioning issues for a couple years where we had to fix it multiple times a year. We discussed the issues with our current air conditioning repair company who said the problem was the ac was getting near end of life and was struggling to keep the house cool when it got hot out. We asked them to give us a quote to replace the system. The person who came out only wanted to sell us on heat pumps and a lower quality air conditioner than what we had. So we contacted Haller to come out to give us a second opinion. One of their sales people ( Alex Steffy) came out looked at our current system and provided us with a variety of options to address our issue. He was very professional knowledgeable and polite. He explained why we had issues and how we should possibly remedy them. He provided 3 separate quotes outlining exactly what what equipment we would be getting and the cost for each option. The installation was done quickly and professionally by two gentlemen. The even offered a 5 year warranty though Haller in addition to the 10 year warranty by carrier. They may be a bit more expensive but I believe the service and care your get from them is worth the extra money.

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.
