Many homeowners don’t think much about their HVAC system until something goes wrong. But regular HVAC maintenance is important if you want your system to run properly and efficiently all year long. At the very least, you should schedule maintenance twice a year—once in the fall for heating and once in the spring for cooling.
If you haven’t had a tune-up in a while, here are the signs that you may need HVAC system maintenance.
It Has Been More Than a Year Since Your Last Tune-Up
If it has been over a year since your last tune-up—or you can’t remember when it happened—it’s time to schedule maintenance. HVAC systems need at least two inspections per year to work efficiently.
Regular tune-ups help technicians catch small problems before they turn into expensive repairs. They can also improve system performance and extend the life of your equipment. Skipping maintenance may seem like a way to save money, but it often leads to higher repair bills later. A maintenance plan is one of the best investments homeowners can make.
Higher Than Normal Bills
It’s normal for utility bills to go up during the hottest and coldest times of the year. But if you notice higher-than-normal charges or sudden increases, your HVAC system may be struggling.
A tune-up can help restore efficiency and prevent your energy bills from rising. If something feels “off” and your bill jumps unexpectedly, call your HVAC technician for an inspection.
Low Airflow
If you turn on your AC or heat and notice weak or reduced airflow, it’s a sign that something is wrong. Poor airflow may be caused by clogged filters, duct issues, or mechanical problems inside the system.
A tune-up will help identify the cause and prevent further damage.
Frequent Issues and Repairs
Most HVAC systems don’t fail without warning. Instead, they show small signs first—like frequent repairs, repeated breakdowns, or parts wearing out.
If you find yourself calling for service often, schedule a maintenance visit. A technician can help you decide whether a repair is enough or if a system replacement would be more cost-effective.
You Hear Unusual Sounds Coming From Your HVAC System
Your HVAC system should run quietly. If you notice new or unusual sounds—such as banging, rattling, buzzing, or squealing—it’s likely a sign of a bigger problem.
Strange odors or uneven temperatures are also red flags. Addressing these issues quickly can prevent more serious and costly repairs. Schedule a maintenance appointment as soon as possible so a technician can inspect the system.
Reduced HVAC Efficiency
A system that isn’t working efficiently will run longer, cycle more often, or struggle to reach the temperature set on the thermostat.
Signs of reduced efficiency include:
- AC running all day but not cooling well
- Furnace running constantly but still feeling cold
- Hot or cold spots in your home
If your system is working harder than it should, it’s time for routine maintenance.
You Have an Older HVAC System
Older HVAC systems need more frequent maintenance to stay reliable. As systems age, parts wear out, efficiency drops, and breakdowns become more common.
If your system is 10–15 years old or older, regular tune-ups are especially important. Your technician can also help you decide when it may be more cost-effective to replace the unit instead of repairing it repeatedly.
The lifespan of an HVAC system can be greatly increased with proper maintenance. It is important to regularly schedule HVAC system maintenance, but especially true if you have an older system.
If you are aware of the signs above you can ensure your HVAC system continues to work properly and efficiently throughout the year and especially when you need it the most. Scheduling HVAC system maintenance may not be something you always keep in mind, but it is important for various reasons.
