I got several quotes from a lot of different contractors & I got lucky with this company. For $6100 I didn't want to have any regrets & DD Mech. really came through as promised. My new TRANE AC seems to be installed as promised & it remains to be seen if we'll have lower elect. bills but DD MECH. is a great company to use. The installation was as promised & there were no surprise fees. Thanks DD MECHANICAL!!!!!!
