Dallas / HVAC installation
For a Dallas replacement, ask how each bidder handles the attic air handler, ductwork connections, drain line and thermostat. Request a written list of components and work. If the home has two systems, confirm which are included.

Ask each bidder how they will handle the attic air handler, its platform, the drain pan and drain lines. Those parts affect whether water problems recur. A proposal that covers them in writing is easier to compare than one that lists only the equipment. Ask whether the new air handler will sit in the same location and whether the attic platform and access need to be enlarged for the new equipment.
Ask whether the ductwork was inspected and what repair or replacement is included. If the home has two systems, confirm which are being replaced and how each floor will be served. Ducts in a hot attic can lose cooling through leaks or poor insulation, so ask whether sealing or insulation work is part of any proposal.
Use the TDLR license search to research the business. Request written details on equipment, controls, ductwork, electrical work, permit and removal. Keep the signed scope with the warranty registration. Compare the warranty terms in each proposal, including what labor is covered and whether registration is required within a set period after installation.
