We had been having air conditioning issues for a couple years where we had to fix it multiple times a year. We discussed the issues with our current air conditioning repair company who said the problem was the ac was getting near end of life and was struggling to keep the house cool when it got hot out. We asked them to give us a quote to replace the system. The person who came out only wanted to sell us on heat pumps and a lower quality air conditioner than what we had. So we contacted Haller to come out to give us a second opinion. One of their sales people ( Alex Steffy) came out looked at our current system and provided us with a variety of options to address our issue. He was very professional knowledgeable and polite. He explained why we had issues and how we should possibly remedy them. He provided 3 separate quotes outlining exactly what what equipment we would be getting and the cost for each option. The installation was done quickly and professionally by two gentlemen. The even offered a 5 year warranty though Haller in addition to the 10 year warranty by carrier. They may be a bit more expensive but I believe the service and care your get from them is worth the extra money.

We had an issue with what looked like a tiny drip in the basement, but Nathan who was amazing (friendly, caring and very professional) spent the necessary time checking out all the area. He found a bird had built a nest in the dryer outside vent causing this crazy scenario. He found it and fixed it that same day. 100% satisfied from this service.

Scheduled an estimate for what we thought would be a complicated fix. Arrived on time, pleasant, thoroughly assessed the situation, made his professional recommendations, and didnโ€™t try to upsell me on any extra repairs that werenโ€™t urgent, and actually let us know that the wiring situation didnโ€™t require an expensive replacement or re-wiring, just someone comfortable with that specific wiring and hardware layout. Would call them again.

Jason from Haller-Electric did a great job troubleshooting an issue in our old home. Quickly diagnosing our issue and solving our problem, and he did so with a positive, conscientious and professional attitude. Well done and thanks!
Shawn was excellent as diagnosing a problem that was not previously identified by other technicians. He explained it very clearly and was doing so in our best interest. He was not pushy or come off as โ€œa salesmanโ€, just letting us know what the issue was. I will definitely be requesting him to do all future maintenance and repairs!

The technician, Eric , called in the morning of my ac and furnace installation to let me know he was on his way. Upon arrival he and Connor reviewed the process for the day and layed down plastic to prevent damage to my floors. Another gentleman joined them at some point to complete the job. overall very satisfied with courteousness and professionalism. Haller came recommended and would do the same for anyone looking for installation or yearly maintenance services.
