Comprehensive Diagnostics and Analysis Included in Your Audit

When you schedule a professional assessment, you move beyond simple visual inspections. A true energy audit utilizes advanced diagnostic technology to measure the performance of your home as a complete system. The goal is to gather data that translates into actionable steps for reducing consumption and improving comfort.

Blower Door Testing

The cornerstone of a residential energy assessment is the blower door test. This procedure involves mounting a powerful fan into the frame of an exterior door. The fan pulls air out of the house, lowering the air pressure inside. The higher outside air pressure then flows in through all unsealed cracks and openings.

• We measure the airflow required to maintain a specific pressure difference, usually 50 Pascals.
• This measurement quantifies the home's airtightness.
• Auditors can physically feel or use smoke pencils to locate specific drafts around windows, doors, and baseboards while the house is depressurized.

Thermographic Inspections

Infrared cameras are used to see what the naked eye cannot. Thermal imaging detects temperature differences in the building shell.

• During the summer, we identify areas where heat is penetrating your walls or ceiling.
• In cooler months, the camera reveals heat escaping from the home.
• These images highlight missing insulation, thermal bridges in the framing, and moisture intrusion that could lead to structural damage or mold growth.

HVAC and Ductwork Analysis

Your heating and cooling equipment consumes the majority of your energy. We assess the age, condition, and efficiency rating of your unit. More importantly, we test the distribution system.

• Static pressure tests ensure the system is moving enough air.
• Duct leakage testing identifies if conditioned air is being lost to the attic or crawlspace before it reaches your living areas.
• We verify that supply and return vents are balanced properly to prevent hot or cold spots in different rooms.

Insulation and Envelope Review

We physically inspect the insulation levels in your attic, walls (where accessible), and floors.

• We compare current R-values against Department of Energy recommendations for the region.
• We check for gaps in the vapor barrier.
• We evaluate the condition of weatherstripping on all exterior doors and the seal quality of double or triple-pane windows.

The Assessment Process: From Inspection to Action Plan

Understanding how the audit is conducted helps you prepare for the visit. The process is systematic, non-invasive, and designed to provide a roadmap for efficiency.

• First, the auditor conducts an initial interview and bill analysis. By reviewing your utility usage history from providers like CPS Energy, we can identify spikes in consumption that correlate with specific weather patterns or operational behaviors. This sets a baseline for potential savings.
• Next, a thorough exterior inspection is performed. The auditor walks the perimeter of the property to check the roof, eaves, foundation, and siding. They look for major structural issues, shading from trees, and the orientation of windows relative to the sun, which impacts solar heat gain.
• Subsequently, the interior data collection begins. This involves the setup of the blower door and the use of diagnostic tools throughout the living space. The auditor moves room by room, checking lighting efficiency, appliance loads, and potential safety issues like back-drafting in combustion appliances (water heaters or furnaces).
• Following the physical inspection, ReliaBee Air, Electric, & Plumbing compiles the data into a comprehensive report. This document does not just list problems; it prioritizes solutions based on return on investment.
• Finally, we present the findings to you. You receive a clear breakdown of which upgrades—such as adding attic insulation, sealing ducts, or upgrading windows—will yield the highest energy savings and improved comfort.

Deciding When an Audit is Essential

Homeowners often wonder if an audit is necessary or if they should just start replacing windows or units. An audit is the diagnostic step that ensures you spend money on the right upgrades. There are specific scenarios where an audit shifts from a "good idea" to a financial necessity.

Aging Homes and Drafty Rooms

If your home was built more than 15 years ago, building codes regarding energy efficiency were likely less deeper than they are today. Insulation settles over time, and sealants degrade. If you feel drafts near outlets or notice that some rooms are perpetually hotter or colder than others, an audit identifies the specific failure points in the thermal envelope.

Before Major HVAC Replacements

Installing a high-efficiency air conditioner in a leaky home is a poor investment. If the house cannot retain the conditioned air, the new unit will still run excessively, reducing its lifespan and failing to deliver the promised energy savings. Performing an audit before replacement allows you to "right-size" the new system. Often, after sealing leaks and improving insulation, a home requires a smaller, less expensive HVAC unit to maintain comfort.

Unexplained High Utility Bills

If your energy costs are significantly higher than your neighbors' costs for a similar-sized home, there is a hidden issue. It could be a disconnected duct in the attic or a failing compressor. An audit investigates these anomalies effectively.

Real Estate Transactions

For those buying or selling a home, an energy audit provides transparency. Sellers can use a high-efficiency rating as a selling point. Buyers can use the report to negotiate repairs or anticipate future improvement costs.

Regional Considerations for Efficiency

San Antonio presents unique challenges regarding energy efficiency due to the specific climate and regional infrastructure. The strategies that work in a dry, cold climate do not apply here.

Managing High Humidity

The proximity to the Gulf of Mexico means humidity control is as important as temperature control. An airtight home prevents humid outdoor air from infiltrating the living space. High indoor humidity forces your AC to work harder to remove moisture, not just heat. If the building envelope is leaky, latent heat (humidity) creates a sticky, uncomfortable environment even when the thermostat reads 72 degrees. Our audits focus heavily on moisture control barriers.

CPS Energy and Local Rebates

Local utility providers often incentivize efficiency. Rebate programs frequently require a certified audit or specific diagnostic tests (like duct testing) before approving funds for new insulation or HVAC systems. Ensuring your improvements meet these local verification standards is critical for eligibility. We ensure documentation aligns with local utility requirements to help you maximize available financial incentives.

Seasonal Strain on the Grid

During the peak of summer, the local grid faces immense demand. Homes with poor efficiency contribute to grid strain and are most vulnerable during brownouts or power failures, as they lose their cool air rapidly. Improving your home’s thermal mass helps maintain safe temperatures for longer periods during outages.

Why Professional Diagnostics Matter

Attempting to guess where energy loss occurs often leads to wasted budget on cosmetic fixes that do not lower bills. Professional diagnostics provide the mathematical certainty required to make smart investment decisions for your property.

Certified Expertise

Auditors undergo rigorous training and certification to understand building science. This expertise ensures that fixing one problem does not create another. For example, tightening a home too much without adding mechanical ventilation can lead to indoor air quality issues. Professionals understand the balance between efficiency and safety.

Data-Driven Investment

The result of an audit is a prioritized list of improvements ranked by Return on Investment (ROI). You might discover that air sealing your attic floor costs a fraction of window replacement but offers double the energy savings. This clarity allows you to budget effectively, tackling the items with the fastest payback period first.

Comprehensive Safety Checks

Beyond efficiency, audits cover safety. We check gas lines for leaks and ensure that combustion appliances vent carbon monoxide properly. In tightly sealed modern homes, negative pressure can pull exhaust gases back into the living space. Our diagnostic tools detect these invisible hazards, ensuring your energy upgrades do not compromise your family’s health.

Verified Results

A professional audit offers a baseline. After improvements are made, post-work testing can verify the reduction in air leakage. This proof of performance is valuable for your peace of mind and potentially for the resale value of the home.

The path to a comfortable, efficient home begins with accurate data. Stop throwing money at utility bills without understanding the root cause of the waste. Take control of your home’s performance and start saving money this season.
