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
Daniel diagnosed the problem quickly and explained everything well.
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!
My service tech was very knowledgeable and did an excellent job explaining my system and the condition it is in. He was very professional and friendly.
Outstanding….best technician yet!
Did a great job on our AC installation
We had annual maintenance performed on our air conditioning and then had to make a call later in the week for our garbage disposal. Both times our technicians, Brayden and Trenton, were polite, professional, on time, and efficient. Even the receptionist was on point with our issue, courteous, and a pleasure to speak with.

Each technician provided follow-up advice and key things to be watchful of. We are beyond pleased with the services Haller provides as well as their staff and technicians. The service fee is reasonable and the maintenance contract we have for our A/C is a cost saver.
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.
I used Haller Enterprise to replace some plumbing and was very pleased.
Needed emergency service and they were there within a few hours. Great service. Friendly and efficient.
Brandon did a great job replacing a shower valve. He also cleaned up after the job was complete. We will definitely use Haller in the future.
Excellent Service. Pleasant technician!

Common Heat Pump Repairs Our Team Handles

Heat pumps run year-round in Central and Eastern Pennsylvania, switching between heating and cooling with every season. That continuous demand means problems can develop at any time of year.

Haller’s experienced technicians are equipped to diagnose and repair a wide range of heat pump issues quickly and effectively.

Low refrigerant affects both the heating and cooling performance of your heat pump, leaving your home either too warm or too cold depending on the season. We locate the source of the leak, repair it properly, and recharge the system to manufacturer specifications.

The reversing valve is what allows your heat pump to switch between heating and cooling mode. When it fails, the system gets stuck in one mode and cannot respond to the season. We diagnose the valve and repair or replace it to restore full year-round operation.

Restricted airflow or refrigerant problems can cause coils to freeze, reducing performance and potentially damaging the compressor. Our team identifies the underlying cause and restores proper airflow and operation.

Worn or damaged electrical components can cause your heat pump to short cycle, fail to start, or shut off unexpectedly. Our team safely repairs or replaces parts like capacitors, contactors, and wiring to keep your system running smoothly.

A malfunctioning thermostat can lead to inconsistent temperatures, incorrect mode switching, or a system that won’t respond to settings. We repair or replace faulty thermostats and confirm accurate communication with your heat pump.

If airflow from your vents is weak or your system is making unusual noises, the blower motor may be the problem. We inspect, repair, or replace the motor to restore proper air circulation throughout your home in every season.

Should You Repair or Replace Your Heat Pump?

Deciding whether to repair or replace your heat pump can be a tough choice.

At Haller, we help you evaluate your options honestly so you can make the best decision for your home and budget.

Heat pumps in Central and Eastern Pennsylvania typically last 15 to 20 years with proper maintenance. If yours is approaching that range, it may be more cost-effective to replace it than to continue investing in repairs.

Occasional repairs are normal, but frequent breakdowns can quickly add up. If you’re calling for service multiple times a year, a replacement may provide better long-term reliability and value.

Older heat pumps are less efficient than modern systems, which can lead to higher energy bills. Upgrading to a newer unit can lower your monthly costs while improving comfort across all four seasons.

A good rule of thumb is to compare the cost of the repair to the value of your system. If a repair is expensive and your system is older, investing in a new heat pump may offer better performance and peace of mind.

Frequently Asked Questions

How do I know if my heat pump needs repair?

Common signs include a system that is stuck in heating or cooling mode and won’t switch, weak airflow from your vents, unusual noises like grinding or rattling, ice buildup on the outdoor unit, or energy bills that have increased without any change in your usage. Heat pumps work year-round in Central and Eastern Pennsylvania, so these symptoms can appear in any season. If your system isn’t keeping your home consistently comfortable, it’s best to schedule an inspection.

How quickly can Haller respond to a heat pump repair?

We offer flexible scheduling and 24/7 emergency services to address urgent issues as quickly as possible. In many cases, we can provide same-day service to restore your comfort fast.

Is it better to repair or replace my heat pump?

It depends on the age of your system, how often it’s been breaking down, and the cost of the repair. Heat pumps in Central and Eastern Pennsylvania typically last 15 to 20 years with proper maintenance. If yours is in that range and requiring frequent service, replacement is often the more cost-effective long-term decision. Our technicians will evaluate your system and provide an honest recommendation.

What happens during a heat pump repair visit?

Our technician arrives on time, performs a thorough inspection, and identifies the root cause of the problem. We explain our findings clearly and walk you through your repair options before any work begins. Once you approve the repair, we complete the work and test your system in both heating and cooling mode to confirm it’s running correctly.

Can regular maintenance help prevent heat pump repairs?

Yes, routine maintenance helps catch small issues early, keeps your system running efficiently, and extends its lifespan. With Haller’s Home Comfort Club, staying on top of maintenance is simple. Members receive scheduled tune-ups, priority service, and exclusive savings throughout the year.
