DFW Air Conditioning and Heating is centrally located in North Dallas. This allows us to be at most points of call within 2 hours under emergency conditions and within 24 hours for non- emergency calls. Our primary business is commercial Air Conditioning, Heating and Refrigeration. We also service many residential customers in the metropolitan Dallas / Ft. Worth area and fulfill many scheduled Preventative Maintenance agreements. As the old axiom states, "An Ounce of Prevention is worth a Pound of Cure" This is very true for your home heating and cooling systems. If you do not pay attention to it on a scheduled basis, you will pay attention to it when it fails unexpectantly.
