What Is a Home Energy Audit?

A home energy audit is a comprehensive, diagnostic assessment of your home's energy performance. It goes far beyond a visual inspection. Using specialized equipment like thermal imaging cameras, blower door fans, and duct leakage testers, an energy audit reveals hidden problems that are invisible to the naked eye: missing insulation behind walls, air leaks beneath your attic floor, leaky ductwork in your crawl space, and thermal bypasses that are silently driving up your utility bills every single month.

For Oklahoma City homeowners, an energy audit is the smartest first step before any insulation or weatherization project. Instead of guessing which improvements your home needs, you get hard data and a clear, prioritized plan that tells you exactly where to invest your money for the greatest return. Many of our customers are surprised to learn that the biggest energy problems in their home are not where they expected them to be.

Bo's Insulation has performed energy assessments on hundreds of existing homes across the OKC metro. We specialize in older homes, and we know the common construction patterns, insulation deficiencies, and air leakage pathways that are typical of homes built in every era from the 1920s to the 2000s. That experience means we know exactly where to look and what to recommend.

What an Energy Audit Involves

A thorough home energy audit combines visual inspection, diagnostic testing, and data analysis. Here is what you can expect during a professional energy audit from Bo's Insulation:

Thermal Imaging (Infrared Camera Inspection)

Thermal imaging is one of the most powerful tools in an energy auditor's kit. An infrared camera detects temperature differences on surfaces, revealing patterns that indicate hidden problems. With thermal imaging, we can see exactly where insulation is missing, thin, or displaced inside walls and ceilings without opening them up. We can locate air leak pathways where cold or hot outside air is penetrating the building envelope. We can identify moisture intrusion areas where water may be damaging insulation or framing. And we can find thermal bridges where framing members conduct heat through the building envelope.

The thermal images provide a visual map of your home's energy weaknesses. We share these images with you during the audit walkthrough so you can see exactly what is happening inside your walls and attic. For many homeowners, seeing the infrared images is an eye-opening experience that makes the audit findings tangible and easy to understand.

Blower Door Test

A blower door test is the gold standard for measuring your home's air tightness. We mount a calibrated fan in your front door that pulls air out of the house, creating a slight negative pressure inside. This controlled depressurization exaggerates every air leak in the building envelope, making them detectable with smoke pencils, infrared cameras, or even by hand.

The test produces a measurable leakage rate in cubic feet per minute at 50 Pascals of pressure (CFM50). This number tells us how leaky your home is compared to standards and benchmarks. For a typical 2,000-square-foot Oklahoma City home, we see blower door numbers ranging from 1,500 CFM50 for relatively tight homes to over 5,000 CFM50 for very leaky older homes. That difference translates directly into energy dollars wasted every month.

Duct Leakage Testing

Your HVAC ductwork can be one of the biggest energy wasters in your home, and most homeowners have no idea it is a problem. Leaky ducts in unconditioned spaces like attics and crawl spaces can waste 20 to 30 percent of the air your system produces. That is money you are paying OG&E to heat and cool your attic instead of your living rooms.

We test duct leakage by pressurizing your duct system and measuring how much air escapes. This tells us whether duct sealing should be part of your improvement plan. In many OKC homes, especially those with older flex duct or sheet metal ductwork in the attic, duct sealing provides some of the best energy savings per dollar invested.

Visual Inspection and Assessment

In addition to diagnostic testing, we perform a thorough visual inspection of every accessible area of your home. This includes the attic, where we check insulation type, depth, coverage, and condition. We inspect the crawl space or basement for insulation, moisture problems, and air sealing needs. We examine windows and doors for seal condition and air leakage. We evaluate the HVAC system for age, condition, and sizing. And we review your utility bills to understand your actual energy consumption patterns and costs.

Identifying Air Leaks and Insulation Gaps

The combination of thermal imaging, blower door testing, and visual inspection allows us to create a complete picture of your home's energy deficiencies. The most common issues we find in Oklahoma City homes include:

  • Missing or insufficient attic insulation, especially in homes where original insulation has settled significantly over the decades
  • Empty wall cavities in homes built before the 1980s, when wall insulation was not required by building codes
  • Major attic bypasses around plumbing stacks, chimney chases, dropped soffits, and open interior wall top plates
  • Uninsulated and unsealed rim joists at the foundation level
  • Leaky ductwork in unconditioned attic or crawl space areas
  • Recessed can lights that penetrate the attic floor without air sealing
  • Inadequate weatherstripping on attic hatches and pull-down stairs
  • Missing vapor barriers or insulation in crawl spaces

Your Prioritized Improvement Plan

The most valuable part of an energy audit is not just finding problems. It is knowing which problems to fix first. After completing the assessment, we provide you with a written report that includes a prioritized list of recommended improvements ranked by their cost-effectiveness and impact on your comfort and energy bills.

We rank improvements so you know exactly where your first dollar, and your last dollar, should go. For most Oklahoma City homes, the highest-priority improvements follow a consistent pattern:

  • Air sealing at the attic floor plane delivers the best return on investment and should almost always be done first
  • Attic insulation to recommended R-value levels is the next highest priority, especially when combined with air sealing
  • Duct sealing in unconditioned spaces ranks high because the savings are immediate and substantial
  • Wall insulation with injection foam addresses a major comfort and efficiency gap in older homes
  • Crawl space insulation and encapsulation protect against moisture and energy loss below the floor

Your improvement plan includes estimated costs and projected energy savings for each recommendation, so you can make informed decisions about what to tackle now and what can wait. There is no pressure to do everything at once. Many homeowners start with the top one or two priorities and come back for additional improvements as their budget allows.

OGE Rebate Programs

Oklahoma Gas & Electric (OG&E) offers rebate programs that can significantly offset the cost of energy efficiency improvements in your home. These rebates are available to OG&E residential customers and apply to qualifying improvements including attic insulation, wall insulation, air sealing, duct sealing, and HVAC upgrades.

A professional energy audit helps you maximize your rebate potential by documenting your home's current conditions and the projected savings from each improvement. This documentation is often required as part of the rebate application process. Bo's Insulation is familiar with OG&E's rebate programs and can help you navigate the application process to ensure you receive every rebate dollar you are entitled to.

In many cases, combining energy audit findings with available rebates brings the effective cost of insulation and air sealing improvements down substantially, shortening the payback period and improving the return on your investment.

Frequently Asked Questions

What does a home energy audit include?

A professional energy audit includes a visual inspection of insulation, air sealing, windows, doors, and your HVAC system. It involves thermal imaging to detect hidden insulation gaps, a blower door test to measure air leakage, duct leakage testing, and a utility bill review. You receive a written report with findings and a prioritized improvement plan ranked by cost-effectiveness.

How much does an energy audit cost in Oklahoma City?

A comprehensive energy audit in Oklahoma City typically costs $200 to $500, depending on home size and scope of testing. Many homeowners recoup this cost quickly through the energy savings identified by the audit. OG&E rebate programs can further offset the cost of recommended improvements.
