HVAC, Plumbing & Electrical Services in PA

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..

He was the kindest and most pleasant person to help me. He really is important to your company and he explained everything to me even though I’m no HVAC expert. But he made it make sense. Thank you and God bless!

Safwan was terrific! He was dedicated in diagnosing our AC problem. Great technician!

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.

Troy came out as part of a OneCall maintenance visit. Haller contacted us before he arrived which we appreciated. Troy checked all of our plumbing fixtures. He found no issues nor any potential problems. He was very efficient and pleasant. Thank you Troy and Haller.

Thomas W. was very helpful today. He provided information on a preventive measure I could take in order to keep my air conditioner running more efficiently throughout the summer. Thomas was thorough in his work and provided explanations for what he was doing. He was prompt and polite. Thomas provided a great representation for Haller.

Nick Snavely did a great job replacing our furnace.

Jason Vasquez, Sr. came out to inspect our inside main plumbing drain for a possible clog. He arrived on time, was friendly, thorough and informative about what the problem was. The problem was corrected, and I was informed about future maintenance that may be required to prevent further clogs. Outside line was checked as well to ensure nothing was missed.

He's very friendly & helpful. We prefer to have him back on our next maintenance

I have never had a bad experience with a Haller Technician. Matthew was great! Kind and professional. Great job.

Matthew Thompson was so helpful, friendly, and skilled. He did a wonderful job.

On time and explained everything

Troy was great. Took care of my issue right away and was very nice. Thank you

All Haller staff have always been very polite and professional. I have been dealing with them for a number of years. I would not take my business to anyone else. Haller is your best bet.

We are always happy with Haller Enterprises. Thank you!

Fast, professional, & reasonable estimate.

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, I’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 — 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 Haller’s service and Steve’s desire to really go the extra mile to help me understand my decision.

Very good.

Install of thermostat. Well, done, very professional
