About


Since 1946, All Temp Heating & Air Conditioning, Inc. has been serving Chicago’s northwest suburbs. By offering old fashioned, quality workmanship and dependable 24 hour service, we have grown along with the communities that we serve.

We specialize in servicing and replacing high efficiency 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 are referrals from family and friends.

It can also handle multi-million dollar custom homes with in-floor heating and multi-zone forced air systems. All of our installation crews have many years of experience and continually go above and beyond our customers’ expectations.

The design team uses proven techniques and calculations to engineer the most sophisticated residential systems down to the most basic replacement sizing.
