I needed a legit window air conditioner installer SF residents trust. these guys were incredible. They fixed up a portable unit with a custom cut vent that fits perfectly into the crank window. zero leaks. Finally I can work from home without sweating through my shirt! Best service ever.

Why did I wait so long to hire a pro? I was terrified to put a heavy unit in my historic Victorian in the Mission district. The wood frames are super fragile and the walls are old lath-and-plaster. I didn't want cracked walls. They used a heavy duty no-drill window ac bracket installation SF style that didn't damage anything. solid as a rock. Now my bedroom is freezing cold and street noise is blocked cause of the soundproof window ac seal San Francisco traffic cant get through! Highly recommend.
I live on a 22% grade hill, and just watching them maneuver the motorized stair climber to get the AC unit up to my door was impressive. They even custom cut plexiglass for my weird wavy bay window. Totally seamless experience from start to finish.
Ever tried sleeping in an 85 degree room? I literally couldn't take it anymore. from my old place with standard windows in the Marina district to this new condo in SoMa, getting ac installed is a nightmare. My new building has those weird crank windows that reject normal units. They came out same day and did a custom SoMa portable ac venting setup with thick plexiglass. No drafts! No HOA complaints! total lifesavers!!!
I was roasting in my top-floor apartment. Booking the service was super easy, and the technician was incredibly polite. A total lifesaver. Thank you guys!
