During this pre-appointment call, we'll also schedule a convenient time for our visit and address any questions you may have. We want you to feel informed and at ease throughout the entire process.
Comprehensive Energy Analysis
When we arrive at your home, we'll conduct a thorough assessment of your energy consumption patterns and household systems. Using advanced diagnostic tools, we'll identify opportunities to improve efficiency and enhance your family's comfort.
Our analysis will cover areas like insulation, air leaks, HVAC performance, and home performance. We'll provide you with a detailed report outlining your home's current energy profile and outline personalized recommendations.
Your decision to prioritize comfort and efficiency is an excellent first step toward saving energy and reducing costs in today's climate.

ProBono LLC believes in empowering homeowners with knowledge and options. We provide clear information about potential improvements so you can decide what works best for your home and budget.
Prepare Your Questions
Before your assessment day, compile a list of specific questions about your home's energy concerns. Consider topics like drafty areas, temperature inconsistencies between rooms, high utility bills, or moisture issues you've noticed. 
We are prepared to address concerns about your HVAC system efficiency, air leakage points, and prioritizing improvements within your budget. Having these questions ready ensures you'll get the maximum value from your assessment.
Schedule Adequate Time
Set aside 2-3 hours for your energy assessment to ensure we can thoroughly evaluate your home's efficiency profile. This timeframe allows us to conduct comprehensive testing, identify all potential improvement areas, and answer your questions in detail without rushing through important steps. A properly timed assessment leads to more accurate recommendations and better results for your home.

Pressure Panning
Pressure panning identifies duct leakage by measuring pressure differences across closed registers while the system is running.

This diagnostic test reveals hidden losses in your HVAC system that standard visual inspections miss.

Fixing identified leaks can reduce energy waste by 10-30% and improve room-to-room comfort.
