What a fantastic experience. Emergency Saturday service for no heat. Turned into needing a new oil burner and water heater. Not an easy task but it was so awesome that they went above and beyond to get everything up and running so quickly.

Haller has always given me the best customer service no matter what time of day/night it is. Emergencies are handled promptly and the best advice given to ensure the best solution is reached. The personal testimonies of the employees are good to hear. They do not just push product on you but are straight forward in your options and requirements. The employees are respectful, quick, and thorough. They are knowledgeable even if you call in to ask a question. I would and have recommended them for service.

We have been loyal customers of Haller for 18 yrs and have always been more than happy with their installations and maintenance policies. Jonathon serviced out HVAC units today and explained everything in detail as far as the health of the systems and any recommendations to be made. Having a service contract has proved invaluable in getting swift repairs when problems strike. I highly recommend this company to everyone. Update : Carlos was our technician for the last 2 preventive maintenance visits. He was very patient in explaining everything and took extra time to show us very useful photos of our ducts. We want to recognize his outstanding service.

Had to replace water heater and radiator due to flooding, Haller made it easy and prompt! Very quick turnaround from initial inspection to replacing the system with a combi-water heater and boiler, very clean, professional, and fantastic work! HVAC techs Caleb and Kaz explained how the new system worked very well and what kind of maintenance I can expect. I will absolutely be going back to Haller again and again for work.

We had a drain flooding into the basement. Vincent came on an emergency call and went above and beyond to find the issue and fix it. He was very accommodating, knowledgeable and kind. Worked quickly and solved our issue with recommendations on things that might need repair in the future.
