I have been working with Haller for several years for my whole house generator. The techs have been super friendly and informative, which I really respect because I like to know how these things work! Very reasonable prices too! They were also the only service company that I was able to find to work on my generator, because everyone else didnโ€™t want to touch it since they โ€œdidnโ€™t install itโ€โ€ฆ I have no idea who installed mine because it came with the house and the previous owner didnโ€™t leave us that info. Haller has definitely been a life saver for my generator!
Complete HVAC system installation was done flawlessly and efficiently. Consultation and service was professional from the start to end.
