Your HVAC system plays a major role in keeping your home comfortable throughout the year, but there is plenty of misinformation about how heating and cooling systems actually work. Following the wrong advice can increase energy consumption, reduce comfort, and even put unnecessary strain on your equipment.
At Home Comfort Services, we help homeowners in Grand Junction and the surrounding areas get more from their heating and cooling systems. Here are some of the most common HVAC myths homeowners still believe and what you should know instead.
Myth #1: Turning the Thermostat Way Down Cools Your Home Faster
When your house feels too warm, setting the thermostat to 60 degrees might seem like a quick way to cool things down. Unfortunately, your air conditioner generally won’t cool your home faster just because you’ve selected a much lower temperature. Instead, the system may simply continue running longer as it tries to reach the setting. This also applies to your heating system, so don’t crank the setting up to 80 degrees in the winter either. That can waste energy and put additional wear on HVAC components.
Choose a comfortable, realistic thermostat setting and give your system time to do its job. If your home consistently struggles to reach the desired temperature, there may be an underlying problem requiring a professional AC repair or heating repair.
Myth #2: Closing Vents in Unused Rooms Saves Energy
It sounds logical: If you’re not using a bedroom, why pay to cool or heat it? But don’t close those vents just yet. Central HVAC systems are generally designed around a specific amount of airflow. Closing multiple supply vents can interfere with that airflow and create pressure imbalances rather than delivering the savings you expected.
If different areas of your home are consistently too hot or cold, don’t automatically start closing registers. Uneven temperatures could indicate issues involving your ductwork, insulation, system sizing, or airflow.
Myth #3: HVAC Maintenance Is Only Necessary When Something Breaks
HVAC maintenance is a preventative measure, so think of it similarly to your yearly doctor visits. Maintenance is designed to make sure your system is healthy, rather than to address an active repair need. Routine maintenance gives our technicians an opportunity to inspect important components, check system operation, clean equipment, and identify developing problems. That’s why we recommend annual pre-season HVAC checkups, with cooling equipment ideally checked before summer and heating equipment before winter. Scheduling an AC tune-up and heating tune-up can help keep your equipment operating efficiently and reduce the likelihood of an inconvenient surprise during extreme weather.
Myth #4: Bigger HVAC Systems Are Always Better
Many think that more cooling or heating capacity must mean better comfort. However, it’s important that your HVAC system is properly sized for your home, as both oversized and undersized systems can cause problems. An oversized system may reach the thermostat setting quickly and then shut off, resulting in frequent short cycles that strain the system. In cooling mode, short run times can also make effective humidity control more difficult. Meanwhile, undersized equipment may run excessively while struggling to maintain comfortable temperatures, which will drive up your energy bills and increase wear and tear on your unit.
If it’s time for a new HVAC system, make sure to work with professionals for your AC installation or heating installation. At Home Comfort Services, we carefully consider your home’s actual heating and cooling requirements to determine and install the right size system for your home.
Myth #5: Air Filters Only Affect Indoor Air Quality
Air filters certainly play an important role in trapping airborne particles and improving your indoor air quality, but they also affect HVAC performance. A dirty filter can restrict airflow, forcing your system to work harder to circulate conditioned air. You should check your HVAC filters every month, particularly during periods of heavy heating or cooling use. Filter requirements vary depending on your HVAC equipment, household conditions, pets, and filter type, so replace them as needed, typically every one to three months.
Myth #6: If the HVAC System Runs, Everything Is Fine
A functioning HVAC system isn’t necessarily a healthy or efficient one. Unusual noises, higher utility bills, weak airflow, inconsistent temperatures, frequent cycling, and strange odors can all indicate developing problems even when the system still heats or cools your home.
Addressing warning signs early may prevent a smaller issue from becoming a larger repair. If your furnace isn’t performing normally or your AC is making concerning sounds, scheduling HVAC repairs sooner rather than later can help you understand what’s happening.
Myth #7: New HVAC Equipment Doesn’t Need Maintenance
A newer system may be efficient and reliable, but it isn’t maintenance-free. Filters still become dirty. Outdoor equipment can collect debris. Electrical connections and mechanical components can develop problems over time. Regular professional attention can help protect performance and keep your system operating as intended.
Rather than assuming new equipment can be ignored for several years, consider a preventative maintenance agreement that makes ongoing HVAC care easier to manage.
