Most homeowners know the basics of keeping their heating and cooling system running, like swapping the thermostat setting when seasons change or calling for help when something breaks. But HVAC professionals think about things a little differently. With years of experience maintaining, repairing, and installing systems, they see firsthand how small details can impact efficiency, lifespan, and comfort.
The good news is that you do not need a license to adopt a few of their best habits. Here are insider tips straight from the pros that the average homeowner may not think about but that can make a big difference in how your system performs.
Change Your Air Filter More Often Than You Think
If you have heard that you only need to change your air filter every three months, you are not alone. That is the most common advice floating around. But in reality, that timeline is more of a “one-size-fits-all” suggestion. The truth is, your household plays a big role in how often you should swap filters.
- Pet owners should expect to change filters every 30 days since fur and dander clog filters quickly.
- Families with kids will also benefit from fresher filters more often since there is typically more foot traffic stirring up dust.
- Allergy sufferers may need monthly changes to keep indoor air quality high.
Neglecting filter changes is one of the fastest ways to overwork your system, increase your energy bills, and reduce airflow throughout your home.
Pro Tip: Write the date directly on the filter frame when you install it. That way you can quickly see if it is due for a swap instead of guessing.
Location Impacts Thermostat Accuracy
Your thermostat is like the brain of your HVAC system. It tells your equipment when to kick on and when to rest. But what if it is getting the wrong signals?
If your thermostat is located in direct sunlight, near drafty doors, or close to appliances that generate heat, it could be tricked into thinking your whole house is hotter or colder than it really is. That leads to unnecessary run times, uneven comfort, and higher bills.
Pro Tip: The best place for a thermostat is on an interior wall in a central area of the home, away from windows, vents, and heat sources. If you are not sure yours is in the best spot, an HVAC technician can advise on relocation.
Keep the Area Around Your Outdoor Unit Clear
Your air conditioner’s outdoor condenser works by expelling heat pulled from inside your home. But if the area around it is blocked, that heat has nowhere to go.
Obstructions like leaves, overgrown shrubs, mulch, stacked lawn chairs, or even kids’ toys can all restrict airflow. When airflow is restricted, the system works harder, increasing wear and tear while also driving up your energy use.
Pro Tip: Keep a 2–3 foot clearance on all sides of your outdoor unit and at least 5 feet above it. Check the area every season and especially after storms. A little landscaping can go a long way toward efficiency.
Listen to What Your System Is Telling You
Professionals often diagnose issues simply by listening. That is because HVAC systems are designed to run relatively quietly. When unusual noises crop up, they are usually a sign that something is off.
- Rattling could mean a loose panel or internal part.
- Buzzing often points to an electrical issue.
- Hissing may signal a refrigerant leak.
- Clanging or banging could be a motor or blower problem.
The earlier you catch these warning signs, the more likely you are to avoid costly breakdowns.
Pro Tip: If you notice strange sounds, do not ignore them. Turn off the system and call a professional. Continuing to run the system could cause additional damage.
Pay Attention to Humidity Levels
Comfort is not just about temperature. It is also about moisture in the air. High humidity can make your home feel warmer than it is, forcing your system to run longer. On the flip side, air that is too dry can be uncomfortable in the winter and may cause wood furniture or flooring to crack.
Pro Tip: Whole-home humidifiers and dehumidifiers can help keep your indoor air balanced year-round. Ask your HVAC provider whether one of these add-ons would be a good investment for your home.
Do Not Block Vents and Returns
It is tempting to place a couch against the wall or throw a rug over a vent, but blocking airflow makes your system less efficient. The same goes for return vents that pull air back into the system for reconditioning.
Pro Tip: Walk through your home once a season and make sure all vents and returns are open, clean, and unobstructed. Even small changes, like shifting furniture a few inches, can improve airflow.
Small Details Add Up to Big Efficiency
HVAC pros know that comfort is about more than just equipment. It is about habits. From running ceiling fans counterclockwise in summer to closing blinds during the hottest part of the day, the small things matter. Every step you take to reduce strain on your system helps it run more smoothly and extends its lifespan.
Pro Tip: Think of HVAC care like car maintenance. Just as oil changes keep your vehicle running reliably, routine attention keeps your HVAC system efficient and problem-free.
