Coil Company has been an industry leader in building air handlers for replacement and add-on applications for decades. We bring a proven unit design and the newest technology to deal with the special requirements of the existing facility. Matching existing footprints, shipment, and job site breakdown allows even the tightest units to be replaced. Many times an owner can replace an old antiquated design rather than refurbishing the existing one. Coil Company can create the perfect fit!
