What our Chicago customers say
Gregory was on time, straight to the point and efficient. We needed to add some refrigerant to our AC, and it was a reasonable price including the initial service call fee. I will definitely have Otter come back out in the Fall for a furnace checkup.

Jeff and Greg were awesome. They were able to schedule a visit within a reasonable amount of time. Greg was thorough and went above and beyond, cleaning out our unit without charging us. He gave a detailed report of his findings and gave me options with pros and cons for each. All in all it took him...

Otter was great to work with. They were so professional. Not only did they install a great air conditioner, they made sure to walk me through everything they did so that I understood everything. I will definitely be calling them again. They are the best!
