Based on 2400 reviews

Came for furnace maintenance, ended up rewiring it correctly (someone else installed) and rewired the thermostat as well. Thankful we’ll now have energy saving heat. Good catch! Went with the package since we’ll be having them out for more services!

Thank you John B. For taking care of our leaky pipes. You went above & beyond to get the problems sorted out & water back on, all while keeping a professional demeanor and sense of humor.

Austin Black was the technician to service my furnace and hot water heater. He is knowledgeable, professional and personal. He explains in detail the service performed. He answers all our questions and concerns. He takes pride in servicing our home. I look forward to having him service my home next year.

Jonathan Dickson

Ron from Haller came to take a look at my AC. I could not have been more pleased with his service. He walked me through step by step what he was going to do and why he was going do it. He was upfront about pricing and he was very patient with all my questions. In the end I decided to move forward with a new unit. And because of Ron explaining everything so well I have no reservations with going with the new unit. I would also like to mention that he did not push a new unit. He simply gave me all the viable options based on the diagnostics he ran. I was using a previous company. But moving forward I will be using Haller!

Anthony Barajas

Support was excellent.

Everyone on your team is so professional, knowledgeable, polite, and friendly. It is a pleasure working with you.

Tavi and Dallas installed a new Carrier Infinity HVAC system to replace our aging system. They also installed an Aprilaire E80 dehumidifier which has in a few days changed the basement air quality. The work was completed professionally and respectively taking into consideration input from the owner. Travi and Dallas worked well together and they both took pride in their work and the results showed. Nate on the Sales Team and Paul supervising Engineer identified corrections to existing duct work which has resolved low airflow issues to the 2nd floor. We have already experienced an evenness of temperatures between the 1st and 2nd levels. Would highly recommend Team Goodco / Haller.

Water heater maintenance was superior by Johnathan. Recommended anode replacement. He added a valve on the hot water side to provide for easier isolation for maintenance.
Since anode replacement was performed during routine inspection I received a 50% discount on Anode.

I highly recommend Haller for all your HVAC needs. Making an appointment, on line, is easy. The employees who came did a great job.

Our service tech, Kurtis Snyder, was excellent. Answered our questions, thorough check of systems and cleaning of dryer vent.
