WELCOME, since 1968 A & S Unlimited Heating and Cooling has been serving Oakland and Macomb county Michigan.

For maintenance, repair, replacement, upgrades and accessories, we are your number one choice.  At A&S we 
look to carry the best brands and parts we can find.  Whenever possible made in the USA products are our first choice.  

When you call A&S to schedule an appointment, we do not schedule 8 to 12 or 12 to 5.  We will provide you
with an appointment time that is convenient for your schedule.  Our first appointments are typically 8 am.  Later in the day such as 1 pm, we will schedule for 1 ish.  This means we will be as close to 1 as possible, we will call you when our technician is on the way.  Providing convenient appointments is the first step to great customer service.  At A&S great customer service is what we are all about.

A & S Unlimited employs only the best technicians.  Our technicians are clean cut, drug free, have good driving records and provide friendly and courteous service to our customers.   

A & S Unlimited services all brands of residential and commercial heating and cooling products.  We choose to install Amana furnaces and air conditioners as this is the best units we can find at this time.  

We are excited to announce our new division AMERICAN GRILL AND PATIO  offering our customers gas grills and patio furniture made in the USA.  Our showroom is currently being updated to include these products.
