My central air that was 22 years old finally went. I called Haller on a Wednesday, Curtis was out on Thursday to give me a quote on a new system. He was punctual, professional, and informative. I received the completed detailed quote the same day and was able to get a full install the following Tuesday. The two men who did the install were fantastic. Quiet and cleaned up after themselves. Gave me a full educational tour of the new unit. New unit works wonderfully. Very pleased with the whole experience. Highly recommend.

DO NOT HIRE THIS COMPANY. They scheduled an appointment with a window between 12 noon and 5 pm today which is a Saturday. No one showed up. I called three times asking for an ETA. Was told plumber was held up on another job. No ETA nor offer to send someone else. It's now 8:12 pm and not a word from any of them. Was told too they had no way of getting in touch with the technician but would send an email to the scheduling team or some other group. Email? No one likes to have their time wasted especially me but if you're someone who does, feel free to call them. Just don't expect service.

Scheduling with Haller is super easy, and they have great communication. We just called them for a hot water heater that keeps shutting off. Gabe is fantastic. He came out and diagnosed the root cause, which was a blocked chimney. We're so glad he put in the work to find the actual issue!

My furnace wasn't staying on and called Haller Enterprises and Keegan the dispatcher was very kind and patient in assisting to get a tech to service my furnace. They were unable to do it that day but was quick to service the next following day. They worked with my work schedule so that I could still get service. Phil the tech was very knowledgeable and explained everything that needed to big fixed and why. The price was fair. I highly recommend Haller Enterprises! You will not regret it! I will definitely be using other sevices. First time customer soon to be long term customer.
