Customer Reviews

My husband and I found Spengler after a not so great experience with an a/c company over the summer. We called Spengler due to great online reviews and they did not disappoint! They came out the same day our furnace broke and offered professional service and were friendly. My husband appreciated that they explained all the options and what was actually wrong with our furnace instead of just trying to charge us a lot of money. I will definitely be using them again in the future.

GREAT SERVICE.....GREAT WORK!!!! I contacted Spengler Company to do some bathroom remodeling for me since they had done some water heater and a/c unit work for me in the past. Since I was impressed with the work done then, as well as their professionalism, I decided to contact them for this project as well.
