Energy efficiency should be a top priority for every homeowner, especially when it comes to their heating, ventilation, and air conditioning systems. HVAC units make a big impression on your personal carbon footprints, so it’s best to ensure they’re performing in a way that provides comfort and safety without wasting money and energy. Here are six signs your HVAC system is not energy efficient, costing you and the environment dearly.

Rising Energy Bills
The most obvious sign that your HVAC system isn’t energy efficient is an unexplained rise in your energy bills. While seasonal changes affect energy usage, a consistent rise in costs without a corresponding increase in usage suggests inefficiency. Consult with your gas or electricity provider if you suspect your rates are higher than they should be because of your home or devices. They should be able to provide some good advice on how to lower your bills.
Uneven Temperature Distribution
Is your home running hot and cold in different places? Higher and lower temperatures in different rooms may mean your HVAC system is struggling to maintain a consistent temperature. Such inconsistency generates increased energy consumption as the system works overtime to balance the temperature.
Frequent System Cycling
Is your system constantly turning on and off or running nonstop? It may be a sign of an issue like poor thermostat placement, a malfunctioning thermostat, filters that are filthy or blocked, or a system that is simply of inadequate size. Hire a technician to come in and perform an inspection on your system. They may discover a simple solution that’s inexpensive to fix but will save you money in the long run.
Noise!
No HVAC system is perfectly silent, but if your system produces unusual or excessively loud sounds, it may be struggling to supply you with warm or cool air. Rattling, banging, and hissing noises often suggest parts of the system are working harder than they should be, leading to higher energy use. Again, a technician can make suggestions or repairs that will restore the system’s efficiency. Of course, it may also be time for a new HVAC system. Many last about 15 years or so with regular care and maintenance (more about this later).
Poor Air Quality
Most HVAC systems do more than provide temperature control. Many are equipped with filters and systems that purify the air. If you notice more dust everywhere, higher or lower humidity levels, and allergic reactions in individuals living under your roof, it could be a sign your system’s filters are clogged or that the system itself is inefficient. First, learn how your system’s filters work, then check and change them periodically.
Age of the System
All good things must come to an end, even efficient HVAC systems. As mentioned, most HVAC systems have a life span of 10 to 15 years. If your system is older, it’s more than likely less energy efficient than modern models. Older systems demand more frequent repairs as they age, which adds to your overall maintenance costs on top of those pesky rising utility bills.
What’s Next?
Schedule periodic maintenance for your system, preferably before summer and winter. A technician will inspect, clean, and adjust or repair any problems in your system. Have a programmable thermostat installed. This allows you to set specific temperatures for different times, reducing your HVAC system’s workload, making it work smarter, not harder. Perform an energy audit on your home, looking for leaks, drafts, and other inefficiencies like poorly insulated attics.
Those are just six signs your HVAC system is not energy efficient. Pay attention to these signs and take proactive steps to improve your HVAC system’s efficiency. You’ll save money and modulate your environmental footprint at the same time!
