Ricardo provided our fall tune-up. He was very thorough and answered any questions I had regarding our heating system. In addition, he was very personable and completed the work in a short amount of time allowing me to free up the rest of my day. Any time I call Haller they are friendly and able to answer any of my questions. I would recommend them for future HVAC needs.

Haller HVAC technician Kenneth M. came to my home to inspect my HVAC system. As a part of the "Home Comfort Club," I was scheduled for a furnace check-up. Kenneth very patiently explained to me what he was doing, and how my system measured on his instruments. He made some recommendations for me to consider. He was professional, efficient, and friendly. I much appreciate Haller technicians taking their time to educate me on the various systems in my home.
Did great work courteous and friendly updated us frequently on what was going on with the job did many jobs replaced water heat, replaced outside water tap replaced floor drain

Michael was prompt and efficient. He chose an option to solve my outlets problem that saved me time and money. He was exceptionally knowledgeable and explained what he was doing as he was doing it so a non-expert could understand it. I learned from the experience and now have a working outlet. I'll call upon Haller again if I need more work done. Thank you, Michael!
