We specialize in servicing and replacing high efficient heating and cooling systems for residential and light commercial applications and have become a leader in our marketplace by offering competitive pricing and exceptional customer service.  Being a family owned company, we take pride in our work.  Many of our customers have been with us for a number of years and most of our new customers come by referrals from family and friends.

All Temp employs factory trained and certified service technicians who are continuously updated with the latest information and service methods.  They are available 24 hours a day, 365 days a year for peace of mind and year-round comfort.  We service all makes and models so our customers can be sure that their unit will be serviced in a professional and timely manner. 

Our installation department handles jobs as small as humidifiers and as large as 125-unit town home developments.  It can also handle multi-million dollar custom homes with in-floor heating and multi-zone forced air systems.

The design team uses proven techniques and calculations to engineer the most sophisticated residential systems down to the most basic replacement sizing.  All of our installation crews have had many years of experience and continually go above and beyond our customers' expectations.

All Temp Heating & Air Conditioning is located at 124 E. Liberty Street, Wauconda, IL, just east of Main Street on Route 176.  This location is central to our large service area.  A fully stocked warehouse and parts department ensures that we can handle any situation.
