Forensic Home Comfort & Efficiency Diagnostics

100% independent, data-driven building science for Southern Arizona homeowners.

You shouldn’t have to guess why certain rooms are always hot, why your energy bills are skyrocketing, or why your indoor air feels stale. Comfort Geeks provides rigorous, unbiased diagnostic modeling and field-testing. Because we do not sell, install, or service HVAC equipment, our data is entirely conflict-free—giving you the exact scientific roadmap you need to permanently fix your home’s climate.

Stop Guessing. Start Measuring.

Most indoor comfort issues aren’t actually caused by a “broken AC unit”—they are caused by hidden building science failures like thermal bypasses, duct leakage, unbalanced static pressures, or improper system sizing. We deploy advanced diagnostics like blower door testing, thermal imaging, and precise ACCA calculations to find the root cause of your home’s chronic issues, ensuring you invest in real solutions instead of expensive equipment overrides.

Targeted Diagnostics, Proven Corrections

We are on a mission to clean up the local residential market and hold installation standards accountable. Through this targeted regional initiative, we help Southern Arizona homeowners maximize their comfort and protect their financial investments across two critical phases:

Pre-Purchase Protection: If you are preparing to replace an aging system, we run independent calculations and verify your contractor’s proposals before you sign a contract. This ensures you don’t get stuck with an oversized, overpriced unit pushed by a commission-driven retail salesperson.
Post-Installation Optimization: If you have already invested in a newer system but find it running inefficiently, short-cycling, or failing to cool certain rooms, we run forensic diagnostics to uncover the installation and ductwork flaws your contractor missed.

Buying a new HVAC system without independent, third-party data is like buying a custom prescription without seeing a doctor first. We provide the unbiased data that forces installation contractors to build your system correctly the first time.

Homeowner Diagnostics FAQs:

Why can't my new HVAC system be sized using square footage per ton?

Sizing an HVAC system strictly by square footage is an outdated “rule of thumb” that leads to massive comfort issues. Consider two identically sized 2,000 sq. ft. homes in Tucson—one built in 1960 with single-pane windows, and one built today to modern energy codes. They have vastly different thermal needs. Sizing by square footage results in oversized equipment that short-cycles, fails to remove humidity, and wears out years ahead of schedule.

Why shouldn't I just replace my current 3.0-ton system with a new 3.0-ton system?

Assuming your old system was the correct size is a massive gamble. Builders frequently put oversized equipment in homes during mass production, and subsequent home improvements (like new windows, added insulation, or solar additions) change your home’s heating and cooling loads completely. Furthermore, two “3-ton” systems from different manufacturers can vary by thousands of BTUs in actual cooling capacity. We run real calculations to find your actual load requirements.

What exactly do I receive with a Home Diagnostic consultation?

You receive a comprehensive, highly targeted physical audit of your home’s thermal envelope and mechanical performance. Because we address two distinct scenarios, your specific deliverables are tailored to your goals:

For System Replacement & Pre-Purchase Consulting: You receive an un-biased, permit-ready design package powered by definitive building science field data. We utilize blower door testing and duct blaster diagnostics to measure your home’s actual airtightness and duct leakage rate. This data is fed into your true ACCA Manual J & S reports, giving you an exact equipment specification guide you can hand to any installer for flawless, apples-to-apples bidding.
For Performance Troubleshooting on Existing/Newer Systems: If you are trying to solve chronic comfort issues or investigate an inefficient newer system, you receive an advanced multi-point forensic performance report powered by MeasureQuick. This diagnostic suite maps out your system’s real-time operating capacity, precise air delivery, and thermodynamic efficiency, pinpointing the exact mechanical or aerodynamic duct flaws that need remediation.

Do you sell or install new HVAC systems?

Absolutely not. We are strictly independent design and diagnostic consultants, which means we do not sell or install complete, new HVAC replacement systems. By eliminating major equipment sales quotas, we remove the built-in conflict of interest that standard HVAC companies face—we have no expensive boxes to move.

Instead, our focus is entirely on precision diagnostics and targeted optimization. Following our visit, we provide you with a clear roadmap of our findings. While we don’t install new systems, we do provide direct quotes to execute the precise minor repairs, aerodynamic duct modifications, and specialized component upgrades required to permanently solve your home’s climate issues.
