When you think about your monthly utility bills, your heating and cooling system is likely one of the biggest contributors to your home’s overall energy use. But how do you know if it’s working as efficiently as it could? That’s where an HVAC-focused home energy audit comes in.
A home energy audit is like a check-up for your HVAC system. It identifies where energy — and your money — might be slipping away, while offering clear solutions to improve efficiency, reduce waste, and keep your home more comfortable year-round.
At Harbin Heating & Air Conditioning, we’ve seen how a professional energy audit can make a real difference for homeowners in Tennessee and Mississippi. From lowering utility bills to improving indoor comfort, this simple step can deliver lasting results.
What Exactly Is an HVAC Home Energy Audit?
Unlike a general home inspection, an HVAC-specific energy audit zeroes in on your heating, ventilation, and air conditioning system. It’s performed by a licensed contractor, technician, or certified auditor and focuses on finding hidden inefficiencies that cost you comfort and money.
By analyzing your system’s performance, identifying problem areas, and suggesting targeted upgrades, an energy audit can help you:
Lower monthly energy bills
Extend the lifespan of your HVAC equipment
Improve indoor air quality
Keep temperatures more consistent throughout your home
Step 1: The Initial Consultation
Every audit starts with a conversation and a review of your home’s past energy usage. Your auditor will look for patterns — for example, high spikes in heating costs during certain months, or cooling bills that seem unusually high for your home size.
This step sets the stage for a tailored inspection. By understanding your home’s energy habits, the technician can focus attention where it matters most.
Step 2: HVAC Equipment Inspection
Your heating and cooling equipment is the heart of your home’s comfort. During an audit, the technician will carefully examine:
Furnace or Heat Pump – Checking age, size, and overall condition. Systems that are too old or incorrectly sized for your home can waste energy and underperform.
Air Conditioner – Inspecting the compressor, refrigerant levels, and evaporator coils. Low refrigerant or dirty coils can dramatically reduce efficiency.
Thermostat – Ensuring it’s accurate, responsive, and up to date. Sometimes, a simple thermostat upgrade to a programmable or smart model can make a huge difference in comfort and savings.
Step 3: Ductwork Evaluation
Leaky or poorly insulated ducts are one of the most common — and most expensive — problems in home HVAC systems. Even small leaks can cause significant energy loss, forcing your system to work harder and driving up your bills.
Your auditor will check for:
Leaks – Gaps, holes, or loose connections where conditioned air escapes.
Insulation – Especially for ducts in attics, basements, or crawlspaces where temperature differences are extreme.
Airflow – Measuring to ensure air is being distributed evenly and without obstructions.
Step 4: Blower Door Test
This specialized test helps detect hidden air leaks in your home’s structure. By using a blower door to depressurize the house, the technician can pinpoint where outside air is sneaking in — around windows, doors, or even hidden wall gaps.
Air leaks don’t just make your HVAC system work harder; they also make it harder for you to maintain a comfortable indoor temperature.
Step 5: Insulation and Air Sealing Check
Insulation is a major player in home comfort. Without enough insulation — especially in your attic — conditioned air escapes faster, and your HVAC system runs longer to keep up.
The audit will examine:
Attic, wall, and floor insulation levels
Air sealing around windows, doors, and other openings
Upgrading insulation and sealing leaks is one of the most cost-effective ways to boost comfort and cut energy costs.
Step 6: Combustion Appliance Testing
If your system uses natural gas, oil, or propane, safety is part of the equation. Your auditor will test appliances like furnaces and water heaters for proper venting, efficient operation, and carbon monoxide safety.
This step ensures not only energy efficiency but also the health and safety of your household.
Step 7: Equipment Efficiency Ratings
Every HVAC system has an efficiency rating, such as:
SEER (Seasonal Energy Efficiency Ratio) for cooling systems
AFUE (Annual Fuel Utilization Efficiency) for heating systems
During the audit, your technician will compare your system’s current ratings to modern standards. If your equipment falls short, upgrading to a high-efficiency model can mean significant long-term savings.
Step 8: Ventilation and Indoor Air Quality
Good ventilation isn’t just about comfort — it’s about health. Poor airflow, excessive humidity, or stale air can make your HVAC system work harder and can impact your family’s well-being.
The audit will check for:
Blocked vents or obstructions
Humidity levels that could affect comfort and efficiency
Opportunities to improve air quality with better ventilation or dehumidification
Step 9: Detailed Energy-Saving Recommendations
After the inspection, you’ll receive a custom report outlining where your system is underperforming and what can be done about it. Recommendations might include:
Sealing duct leaks
Adding insulation to ductwork in unconditioned spaces
Upgrading to a high-efficiency unit
Installing a smart thermostat
Adding attic or wall insulation
Sealing air leaks around windows and doors
Step 10: Post-Audit Follow-Up
Some audits include a follow-up visit to make sure the improvements you’ve made are working as expected. This step helps verify your investment is paying off in comfort and lower utility costs.
