Aspects of Energy Audit for HVAC Systems
An energy audit for your HVAC system examines and measures how your system currently performs.
A fantastic time of year for HVAC maintenance is spring. Why? The hard winter weather has subsided, and the weather is warming up, albeit it's still not too hot and muggy. To make sure your system is still operating effectively throughout this time, you should get in touch with your HVAC supplier and request an energy audit. Let's address some inquiries regarding what to anticipate from your provider's HVAC audit.
What Does an HVAC System Audit Measure?
An energy audit for your HVAC system examines and measures how your system currently performs. It also shows you how to boost your system’s energy efficiency. After you have an audit performed, your provider can examine the results with you and determine how to make your HVAC system more energy efficient. They can help you take measures to improve your system’s performance while lowering your energy costs.
ENERGY AUDIT TYPES
While the term “energy audit” may sound technical but vague to many people, technicians in the HVAC industry understand that it’s a technical term carefully defined by the professional organization ASHRAE. ASHRAE defines and outlines three different types of HVAC energy audits:
- Level 1: This is the most basic audit level. During a Level 1 audit, your energy auditor performs a high-level walkthrough of your building to collect data about your building systems’ operations. They also review your recent utility bills and interview your building’s operations personnel. The auditor uses these three major steps to identify any major problems in your HVAC system’s operations.
- Level 2: This level is a more in-depth version of a Level 1 audit. Your auditor makes more complicated calculations to determine where you can improve your building’s energy efficiency during this type of audit. They also interview important building personnel so they can gain perspective into the building’s overall operations and energy usage. Then they make a list of potential improvements and changes. If a Level 1 audit is about examining an HVAC system’s current performance, then a Level 2 audit is about improving that performance for sustainability’s sake.
- Level 3: This is the most complex type of audit. It builds on Levels 1 and 2, so your energy auditor collects more data and provides an in-depth engineering analysis of what Level 2’s potential improvements and changes would look like if you implemented them in your building’s HVAC system. This type of energy efficiency audit includes mapping out your energy system’s possible future as well as examining its current performance.

Why Should You Schedule an HVAC Energy Audit?
After reading those definitions, you may think an energy audit sounds complicated, and it is. So why should you schedule one? Well, energy audits work as a form of preventative maintenance. That means that having an auditor examine your HVAC system as a form of routine maintenance will save your system from developing major problems in the future. For example, when your auditor shows up with an HVAC system audit checklist, they can use their inspection checklist to check for common problems, such as air leaks. They can also determine how good or bad your building’s air quality is, so you know whether your HVAC system creates a healthy work environment. In the long run, a basic Level 1 audit can help your system’s components run well and extend your system’s lifespan.
Additionally, you should have a Level 2 or 3 audit performed if you want to improve your building’s energy efficiency and its overall sustainability. These higher level audits help you understand which improvements you should complete to make your HVAC system more energy efficient and what those changes might look like. Then you can go forward knowing which alterations will improve your system’s performance and lower your energy costs.

I think that you can still solve your problem. Better if you read about HVAC, as I once did and found this site https://thehvacservice.ca/vaughan/ where it's possible to find out HVAC services. I hope it will also be practical to you because many people need to have such service to have better houses.
