Eric Moore
Had our power lines to the house taken down during a big storm, the folks at Haller were great at getting out quickly to check out the damage and give us an estimate to repair. We put a down-payment down to reserve service, ended up not needing them, and they promptly refunded our payment with zero fuss. Good experience, I recommend them

Eric Pavelik
From Haller doing a routine check on my HVAC and noticing the the water heater leaking to the estimate to scheduling the replacement… then having to change the appointment because of leaving for a vacation…. Courtesy, professional, and the Plummer that did the job Shane was seriously great. I’m thankful.
Donald Humphrey
The service was extraordinary. My service person was polite, informative and customer centric. This person is the type of person you want engaging with people. I also learned some good ac and furnace tips. I give Shane 5 stars….out of 5.

Nate was very nice to work with and very professional.

Garage toilet replacement.
Opted to provide own fixture and Haller requested for install. Mark Habbershon did a great job in removal, prep work, install, test & cleanup. . Confirmed improved trap dimensions for the new unit and much less likely to clog like old toilet with narrower trap. Very friendly and eager to do a quality job! Bravo Mark!!
Tate Hammer
Repair man was amazing nice and kind , unfortunately it was on the 4th of July and the rates were a lot higher ! But the repair man was great would highly recommend
Terry Kauffman
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.
Linda Carlson
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.
Patricia Barconey
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.

Chatty Reprado
He did an excellent job. 👏 He is very friendly and kind.
Daryl Black
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 (it’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!
Steph Hilsher
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.
Jean Smith
Very professional and tells you exactly what is going on. Highly recommend.
