Our AC Installation Process
At Brennan & Co., a successful installation begins well before we set foot on your property. We take a deliberate, detail-oriented approach to every project to make sure the system we install is the right one for you and your home.
Our AC installation process includes:
- Personalized load calculations. We assess your property's size, layout, insulation, and sun exposure to determine the precise cooling capacity your home requires; no oversizing, no undersizing, just the right fit.
- System selection. Based on our assessment and your comfort goals, we recommend top-tier, energy-efficient models suited to your property and budget, with options that may qualify for Mass Save rebates or other efficiency incentives.
- Professional installation. Our technicians install your new system with meticulous attention to detail, working cleanly and efficiently while respecting your home, privacy, and schedule.
- A full system walkthrough. Before we leave, we’ll walk you through your new system, how it operates, how to get the most out of it, and what to expect going forward.
From the first estimate to the final walkthrough, every installation is handled with the care and expertise that local homeowners have trusted for over 20 years.
