Customer testimonials:

Andrew Miller of Miller Heating & Cooling fixed my AC. Not only did he do a great job, he drove up from the beach to do it on a Saturday, and did not charge me an arm and a leg!! Use this company if you need your Heating or Cooling repaired!!!!! Thanks, J.W.

I called Miller Heating & Cooling to repair my daycare A/C. The repair was made the same day.
Thanks, M.C
 
Last year my A/C was not cooling as well in the past. I had Miller perform a A/C tune-up. The tech showed me why the unit was not cooling (Grass covering the outdoor unit) as well in the past. The tech cleaned the unit and I could feel the difference on the first hot day.
Thanks, R.T
 
My oil burner was not running. Miller was out the same day and had my unit running
Thanks, Ms. M.S
