Best Air Conditioner Installation in Milwaukee WI

They were very prompt, reasonable and friendly. I would recommend them.

Service Technician Sam was extremely friendly; he explained what the options might be and then he worked quickly! Our household is back in shape, and we have met a new neighborhood business to call on again.
BTW - we also appreciate that you advertise in our St. Elizabeth Ann Seton bulletin!

Called O and W Heating on Christmas Eve to help us with our furnace that stopped working that morning.

They sent a gentleman by the name of Scott. He's simply amazing. I'd give him a 10+ thank you Heiden plumbing.

Kurt B offered very friendly service. He gave a detailed description of the possible problems with our furnace, and did not pressure us into a specific decision in how to fix the problem - aka pressure us into spending unnecessary money. We would recommend this company!

My husband and I are both in Real Estate, Lending and restaurants and when we need reliable and professional help they are our go to! Great company wither it's an emergency, which is 24 hours a day or installation call they're great!

Great friendly service

in this time of coronavirus, a handy person needs to be prepared. jerry was supposed to fix two switches, said he would wear a mask if i provided one. can he not be vaccinated working in a person's home???? and not have his own mask???? so we cancelled.
