Madison Home Performance

Madison Home Performance operates as a home performance testing specialist serving Madison, Wisconsin and surrounding communities including Janesville and Monona. The company holds a perfect 5.0-star rating drawn from 32 client reviews, reflecting consistent satisfaction across residential energy audits and HVAC design projects. Their approach centers on diagnostic testing rather than guesswork, positioning themselves as a data-driven alternative to renovation projects that fail to address underlying structural or mechanical issues.

What distinguishes Madison Home Performance is their commitment to objective measurement before prescribing solutions, a philosophy rooted in the W. Edwards Deming principle that without data, opinions replace expertise. They offer tiered energy auditing packages (Tier 1, 2, or 3) testing building shell integrity, health and safety factors, and HVAC systems. Their HVAC design services include Manual J load calculations, system selection, and duct design, while virtual consulting extends their expertise to remote clients who want professional guidance during home visits.

Reviewers consistently highlight technician Stephen Cavill's communication style and technical depth. One client noted Stephen helped them understand the "whole picture" before committing to expensive updates, preventing unnecessary spending. Another client with a century-old home appreciated Stephen's willingness to thoroughly answer questions, describing the process as "downright fun." A third reviewer specifically praised his Saturday availability and the educational component of the assessment, where he explained measurements and their significance in real time.
