About this file

This is a scope of work document for the City of Lewisville, Texas's Minor Housing Rehabilitation Program (HVAC Repair/Replace Program), detailing current HVAC systems across 14 residential homes. The document provides comprehensive specifications for each property, including home size, bedroom count, story configuration, and detailed equipment information for existing HVAC systems. The homes range from 1,016 to 2,312 square feet and feature various equipment manufacturers including Lennox, Amana, Trane, Rheem, Carrier, and Goodman. Current systems vary significantly in age, with some dating back to the 1970s and others installed within the past 15 years. Most recent maintenance work has included minor repairs, freeon additions, component replacements (fans and motors), and drainage cleaning performed between 2018 and 2025.

The competitive sealed bid process seeks qualified contractors to repair and/or replace HVAC units at these 14 homes, with successful bidders required to certify compliance with the Americans with Disabilities Act and all related regulations. The document serves as a baseline assessment of existing conditions to inform contractor proposals and cost estimates. Equipment conditions, installation dates, and maintenance histories are documented to establish the current environment for each property. No specific pricing terms, contract duration, award dates, or other financial information is provided in this scope document, which functions primarily as a technical reference for bidders to develop comprehensive repair and replacement proposals for the residential properties.
