I need it after hours service Omar came out told me the system was frozen remove the filter we let it sit overnight Greg came out the next day putting it back together at no charge so the only thing I had to pay was the after hours service call and they did a great job and we're truly respectful thanks again for everything

Ricardo Colon did a great job servicing both the main unit in the basement and the through the wall unit in our sun room. He also noticed that our water heater needed replacement, which did not have to do.

Very good ; attention to details and efficient

Haller tech came on time & explained service

Omar and his colleague were amazing. Fixed the problem within minutes. Serviced the furnace and gave quotes on additional serves to consider in the future. I cannot express how AMAZING Haller Enterprise has been over the last several years using them. Never have I had any issues whatsoever with any of their technicians. 10/10 recommend every time!!! Omar and his colleague literally saved the day. Thank you so much!!!

Side note: Every single person has been beyond nice and pleasant to work with as well. Really a great company.

Great service. Ricardo did a great job and made good recommendations.

Service contract for standby generator, annual check. Knowledgeable, prompt…. exceptional customer experience.

I just had my annual AC cleaning by Safwan. He did a great job. In fact, he was here last fall to do the furnace cleaning and fixed a long standing problem I was having with my furnace. Very satisfied with his service. I would highly recommend him.

The technician arrived within the allotted window and successfully completed the required maintenance. He was friendly and polite, explained what needed to be done. I am very satisfied with the service.

Just received a quote.

We are very pleased with our experience with Haller Enterprises. The entire process was direct, simple, and efficient from start to finish. They took the time to clearly explain the different HVAC systems that would best suit our home, which made the decision process much easier and gave us confidence that we were choosing the right fit.

The installation was scheduled quickly, the work was done neatly and professionally, and the overall installation was very clean. We also appreciated the follow-up after the job was completed, which showed they truly care about their customers and the quality of their work.

Communication throughout the process was excellent, especially with our salesperson, Anthony. He continued to follow up, address any issues, and help find solutions whenever needed. That level of service made a big difference.

Because our first experience went so well, we reached back out to Anthony at Haller Enterprises to replace our water heater with a tankless system. This time everything was done with text, email and a few phone calls, no late evening meeting. That says a lot about the trust they earned with us. We would gladly recommend Haller Enterprises to anyone looking for quality work, strong communication, and an easy, professional experience.

The tech was great. He was very knowledgeable & helpful in showing me how to get the best out of my Heater/air conditioner

Service was very helpful, we now know that we need a new water pump.
