You and your loved ones don't need to sweat the hot days when Master Mechanical is on the job.  From Mt. Prospect to Buffalo Grove or from Elk Grove Village to Arlington Heights, when the temperature in the Northwest Suburbs begins to sizzle, the cold air will flow on demand when our qualified, certified and expert technicians provide the level of air conditioning service you expect.

We offer air conditioning repair and air conditioning service for residential and commercial air conditioning systems. We'll make sure your air conditioning system is operating at peak performance. After providing a free estimate, we can also install an industry leading air conditioning unit to fit your needs.

A properly sized air conditioner runs at its most efficient capacity. This translates to lower energy costs. Backed by our trained AC service technicians, we'll ensure that your air conditioner continues to operate at that level. If you have an older unit that needs a little TLC, our air conditioning service will allow you to maximize the life of your existing. If need be, we'll repair your air conditioning system or let you know when its time has passed.

Master Mechanical is dedicated to providing our customers with reliable and affordable air conditioning service and repair.  We can also offer an annual service agreement to keep your mind at ease for your family or loved ones.
