To Keep Your AC System Running at Peak Performance, Leave it to Blau
Serving Southeast Wisconsin
A thermostat is a wonderful thing. You flick a little switch, key in a few numbers or twist the dial one way or the other and, voila, increased home comfort! Nice feeling, isn’t it? Except, of course, when things don’t work out exactly according to plan.
That’s where we come in. You see, at Blau Sudden Service, we do all the big and little things to make sure you have crisp, cool air all summer long…with little or no disruption.
“I put this off for years thinking it would involve tile work and who knows what else. What a relief.” - Butch J.


Here’s How We Accomplish That on Your Behalf:
- Annual tune-ups and inspections – Our multi-point tune-up and inspection service is the best way to keep your central A/C system running longer while reducing your home comfort utility costs. Annual system maintenance also enables us to spot small problems before they become bigger and more costly repairs.
- Expert repairs – At Blau, we service all makes and models of central air conditioning systems. More often than not we provide same-day service, and we’re ALWAYS available for 24/7 emergency repair service.
- Our trucks are stocked with hundreds of parts, meaning we can tackle and complete most system repairs with just a single visit to your home.
Most importantly, our home comfort technicians have the training and experience to handle any problem that might arise…with the rest of the Blau team of home comfort professionals on hand to back them up.
If it’s been more than a year since your central air conditioning system was last inspected and tuned up, contact us today. And for expert and prompt system repairs, contact us any time at all.
