Energy Audits
Comprehensive HVAC energy audits that show exactly where your building wastes energy and provide a prioritized plan to reduce costs while improving comfort.
Energy audits in Las Vegas are critical because HVAC systems account for fifty to seventy percent of total energy consumption in Clark County buildings, making cooling and ventilation the single largest controllable operating expense for both homes and commercial properties. Constant Air Balancing and Services performs comprehensive HVAC-focused energy audits that identify exactly where your system wastes energy, quantify the dollar cost of each inefficiency, and provide a prioritized plan of improvements ranked by return on investment so you address the highest-value opportunities first.
The Las Vegas desert climate creates energy waste patterns specific to this region that generic energy audits from other markets fail to identify. Oversized HVAC systems that short-cycle in spring and fall but cannot maintain temperature on the hottest summer days. Duct systems that leak conditioned air into unconditioned attic spaces where temperatures reach 160 degrees. Ventilation systems that bring in excessive hot outdoor air because dampers are stuck open or controls are improperly configured. Refrigerant charges that are incorrect because the system was never properly commissioned or has developed slow leaks. These are the high-value findings that our NCI-certified technicians identify through measurement and testing rather than visual inspection alone.
An energy audit from Constant Air Balancing is not a sales pitch for new equipment. It is an engineering assessment that measures your system’s actual performance and compares it to the performance it should deliver. We measure airflow, temperature differentials, refrigerant charge, duct leakage, ventilation rates, and equipment efficiency, then calculate the energy and dollar impact of every deficiency we find. Many of the highest-return improvements involve adjustments, repairs, and maintenance rather than equipment replacement. Fixing duct leaks, correcting refrigerant charge, cleaning coils, and optimizing controls can reduce HVAC energy consumption by twenty to forty percent without any capital equipment purchases.
For commercial properties, our energy audits include utility bill analysis that identifies billing anomalies, demand charge opportunities, and rate structure optimization. We compare your building’s energy consumption to benchmarks for similar buildings in the Las Vegas market and identify where your building falls above the benchmark and why. For homeowners, we focus on the HVAC system, ductwork, insulation, and air sealing that have the greatest impact on comfort and utility costs. Call (702) 840-5163 to schedule your energy audit.
Utility Bill Analysis
We analyze twelve months of utility data to establish your baseline consumption, identify seasonal patterns, detect anomalies, and calculate your building’s energy use intensity. For commercial properties, we review demand charges and rate structures to identify billing optimization opportunities that reduce costs without any physical changes to the building.
HVAC System Testing
We test every HVAC system in your building, measuring airflow, temperature differential, refrigerant charge, amp draw, and operating efficiency. We compare actual performance to manufacturer specifications and calculate the energy penalty of every deficiency. This testing reveals systems running at 60 percent efficiency that could operate at 90+ percent with proper maintenance and adjustment.
Duct System Evaluation
We test ductwork for leakage, insulation adequacy, and airflow delivery to each zone. Duct leakage is one of the largest energy wastes in Las Vegas buildings because leaked conditioned air enters unconditioned attic and crawl spaces where extreme temperatures destroy the cooling you already paid to generate. We quantify the leakage rate and calculate the annual energy cost of duct losses.
Ventilation & Controls Assessment
We evaluate ventilation rates against code requirements and occupancy patterns, assess thermostat and control system programming, and identify scheduling and setback opportunities. Over-ventilation and poor controls are responsible for significant energy waste in Las Vegas commercial buildings, and corrections often require no capital investment beyond programming changes.
Report & Prioritized Action Plan
You receive a detailed report documenting every finding with the associated energy cost, recommended correction, projected improvement cost, projected annual savings, and simple payback period. Recommendations are ranked by return on investment so you can start with the improvements that deliver the most savings per dollar invested and work through the list over time as budget allows.
Measurement-Based Analysis
We measure actual system performance with calibrated instruments rather than quoting from nameplate data. This approach reveals the real efficiency gaps that visual inspections and equipment age assessments miss entirely.
Desert Climate Expertise
We know Las Vegas energy waste patterns. Duct leakage into 160-degree attics, over-ventilation with 115-degree outdoor air, and systems fighting solar heat gain all create region-specific inefficiencies we test for specifically.
Actionable Results
Every finding includes a dollar cost, a recommended fix, an improvement quote, and a payback calculation. You get a prioritized action plan, not a generic list of suggestions. We quantify savings so you can make informed investment decisions.
An energy audit answers the question every Las Vegas homeowner asks in July: why is this bill so high. Instead of guessing, we measure where the energy is going, from duct leakage and airflow to equipment performance and the gap between what your system draws and what it delivers.
We tie the readings together into a clear picture of where the waste actually lives. Often it is a combination, leaky ductwork bleeding 25 percent of the cooling, a coil that needs cleaning, and a system pushing the wrong airflow, each one stacking onto the bill. The audit ranks the fixes by impact so you spend money on what moves the needle, not on a salesperson’s hunch.
This is the measurement-first approach across your whole home, not a single symptom. See diagnostic projects in the gallery.
I was about to spend a fortune on a new system because my bills were crazy. The audit showed it was leaky ducts and a filthy coil, not the unit. They fixed those for a fraction of the cost and my bill dropped right away. Glad I called them first.
How much can an energy audit save me?
Typical Las Vegas buildings reduce HVAC energy consumption by twenty to forty percent after implementing the recommendations from our energy audit. The actual savings depend on the current condition of your system and building. Properties with older equipment, leaky ductwork, and poor controls tend to have the greatest savings opportunities. We quantify the expected savings for each recommendation so you can calculate the return on investment before committing to any improvements.
How long does an energy audit take?
A residential energy audit typically takes three to five hours. Commercial building audits take one to three days depending on building size, number of HVAC systems, and complexity. The on-site work includes equipment testing, duct testing, airflow measurements, and controls evaluation. The written report with prioritized recommendations is typically delivered within one to two weeks after the site visit.
Do I need an energy audit or just HVAC maintenance?
They serve different purposes. HVAC maintenance keeps your existing system running properly and prevents breakdowns. An energy audit evaluates whether your system is operating efficiently and identifies specific improvements that reduce energy consumption. If your energy bills seem high despite regular maintenance, an energy audit often reveals efficiency problems that maintenance alone does not address, such as duct leakage, incorrect refrigerant charge, oversized equipment, or poor control strategies.
Is an energy audit worth it for a home?
Yes, especially in Las Vegas where cooling costs dominate household energy budgets. A residential energy audit identifies duct leakage, insulation deficiencies, air sealing opportunities, and HVAC performance issues that can reduce your cooling costs significantly. Many homeowners discover that their ductwork leaks twenty to thirty percent of conditioned air into the attic, which is essentially cooling the outdoors. Fixing duct leaks alone often saves enough to pay for the audit within one cooling season.
What should I prepare for an energy audit?
Gather twelve months of utility bills for our analysis. Ensure all areas of the building are accessible, including attic spaces, mechanical rooms, and rooftop equipment. Have information available about HVAC equipment age, recent repairs or replacements, and any comfort complaints from occupants. For commercial buildings, provide building operating schedules, occupancy patterns, and any existing building management system access. Contact us to schedule your audit.
