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!

Benefits of a Furnace Replacement in Bethlehem

Replacing your furnace is an investment in comfort, efficiency, and long-term reliability.

If your current system is outdated or unreliable, furnace replacement in Bethlehem can dramatically improve your home’s performance and lower your stress during Pennsylvania’s cold winters. Discover the benefits Bethlehem homeowners notice with a new furnace:

New high-efficiency furnaces installed in Bethlehem use less fuel to produce the same or better level of warmth. Furnace replacement pays for itself through lower monthly bills. That means you can enjoy improved comfort while potentially reducing your monthly heating costs.

An older furnace in Bethlehem is more likely to break down during the coldest stretches of a Pennsylvania winter. A new system provides dependable heating and reduces the risk of unexpected mid-winter repairs.

Modern furnaces distribute heat more evenly throughout your Bethlehem home. You’ll experience fewer cold spots and more consistent temperatures from room to room.

Today’s furnaces installed in Bethlehem homes are built with advanced safety controls and monitoring systems. Replacing your aging unit helps minimize risks such as carbon monoxide leaks and system malfunctions.

Time to Replace Your Furnace? Look for These Signs

Knowing the warning signs of a failing furnace can help you avoid a complete breakdown. These are the situations where furnace replacement in Bethlehem is often the smartest move.

If you’re calling for furnace repairs in Bethlehem more often than usual, those costs can quickly add up. Furnace replacement in Bethlehem is often more cost-effective than continuing to fix an aging unit.

An unexplained increase in heating costs in your Bethlehem home often signals declining efficiency. Older furnaces work harder to produce heat, using more energy while delivering less consistent comfort.

Cold spots or rooms that never seem warm enough can point to a struggling system. As furnaces age, they often lose the ability to distribute heat evenly and effectively.

Most furnaces in Bethlehem have a lifespan of about 15 to 20 years with proper maintenance. If your system is nearing or beyond that range, replacing it can improve reliability, efficiency, and overall comfort in your Bethlehem home.
