When it comes to maintaining a home’s plumbing and HVAC systems, many homeowners rely on advice that has been passed down through generations or found online.
Unfortunately, not all of this advice is accurate. In fact, some of the most commonly believed myths about heating, cooling, and plumbing can lead to unnecessary expenses, inefficient systems, and even costly repairs.
Believing misinformation can cause homeowners to make poor maintenance decisions, overlook critical warning signs, or waste energy.
From thermostat settings to plumbing quick-fixes, there are many misconceptions that need to be addressed.
Understanding the truth behind these myths can help homeowners make smarter choices, keep their systems running efficiently, and avoid expensive repairs in the future.
Pilot Plumbing, Heating and Cooling understands the importance of proper maintenance and energy efficiency.
By debunking these common myths, homeowners can take better care of their plumbing and HVAC systems, ultimately extending their lifespan and improving overall performance.
Myths About HVAC Systems
Heating and cooling systems are complex, and misconceptions about how they work can lead to higher energy bills and inefficient operation.
1. The Lower You Set the Thermostat, the Faster Your Home Cools
- Many people believe that cranking the thermostat way down will cool their home faster.
- In reality, HVAC systems work at a set speed—lowering the thermostat only makes them run longer, not faster.
- The best way to cool a home efficiently is to set the thermostat to a reasonable temperature and let the system work at its designed pace.
2. Closing Vents in Unused Rooms Saves Energy
- It might seem logical to close vents in rooms that aren’t being used, but this actually creates pressure imbalances in the system.
- Blocking vents forces the HVAC system to work harder, leading to increased wear and tear.
- Instead of closing vents, homeowners should consider zoning systems or smart thermostats to improve efficiency.
3. Bigger HVAC Systems Are Always Better
- A larger HVAC system does not mean better performance—it can actually cause short cycling, where the system turns on and off too frequently.
- Oversized units cool or heat a space too quickly, which can lead to uneven temperatures and higher humidity levels.
- Proper sizing, based on the square footage and insulation of a home, ensures better efficiency and comfort.
4. You Only Need to Change Your Air Filter Once a Year
- Many homeowners underestimate the importance of changing air filters regularly.
- Dirty filters restrict airflow, forcing the system to work harder and reducing indoor air quality.
- Filters should typically be replaced every 1-3 months, depending on household dust levels and pet presence.
5. Ceiling Fans Cool a Room
- Ceiling fans don’t lower the temperature of a room; they simply circulate air, making the space feel cooler.
- Running a fan in an empty room wastes energy since fans do not actually reduce heat.
- Using fans alongside air conditioning can help improve comfort while allowing homeowners to set the thermostat a few degrees higher.
Myths About Plumbing Systems
Plumbing problems can range from minor inconveniences to major disasters. Misconceptions about plumbing maintenance can lead to clogged drains, leaks, and costly repairs.
1. It’s Safe to Pour Grease Down the Drain If You Use Hot Water
- Hot water may temporarily liquefy grease, but once it cools, the grease solidifies and sticks to the pipes.
- Over time, grease buildup leads to severe blockages that require professional drain cleaning.
- The best way to dispose of grease is to let it cool and throw it in the trash.
2. A Leaky Faucet Isn’t a Big Deal
- A slow drip may not seem urgent, but even a small leak can waste gallons of water over time.
- Unaddressed leaks can lead to higher water bills and potential damage to fixtures.
- Fixing leaks promptly prevents water waste and maintains plumbing efficiency.
3. Flushable Wipes Are Safe for Plumbing
- Despite being labeled as “flushable,” many wipes do not break down as easily as toilet paper.
- These wipes can cause clogs in household pipes and sewer systems.
- To avoid plumbing issues, it’s best to dispose of wipes in the trash rather than flushing them.
4. All Plumbing Fixtures Work the Same
- Not all faucets, toilets, and pipes are built with the same materials and efficiency standards.
- Older plumbing fixtures may use more water and be more prone to leaks.
- Upgrading to high-efficiency fixtures can help conserve water and reduce utility costs.
5. Chemical Drain Cleaners Are the Best Way to Clear Clogs
- While chemical drain cleaners can dissolve some blockages, they often contain harsh ingredients that corrode pipes over time.
- Frequent use of these cleaners can weaken plumbing and lead to costly repairs.
- A safer alternative is using a plunger, drain snake, or professional drain cleaning services.
The Truth About Water Heaters and HVAC Maintenance
Water heaters and HVAC systems are essential for home comfort, but myths about their care can lead to unexpected failures.
1. Water Heaters Don’t Need Maintenance Until They Stop Working
- Many homeowners assume that as long as their water heater is producing hot water, it doesn’t need servicing.
- However, sediment buildup in the tank can reduce efficiency and shorten the unit’s lifespan.
- Flushing the tank annually and checking the anode rod helps prevent costly breakdowns.
2. HVAC Units Only Need Repairs When They Break Down
- Preventative maintenance is essential for keeping heating and cooling systems running efficiently.
- Routine inspections help catch small issues before they turn into major, expensive problems.
- Seasonal tune-ups improve system performance and extend the lifespan of HVAC units.
3. Setting the Thermostat Higher Heats the Home Faster
- Just like lowering the thermostat doesn’t cool a home faster, raising it won’t speed up heating.
- HVAC systems operate at a fixed rate—turning the thermostat too high simply makes them run longer.
- Gradual temperature adjustments and proper insulation help maintain consistent warmth.
How to Avoid Costly Mistakes and Maintain Efficient Systems
Understanding the truth behind these myths helps homeowners take better care of their plumbing and HVAC systems.
The best way to prevent costly breakdowns is to follow proper maintenance practices and seek professional assistance when needed.
1. Follow Manufacturer Recommendations
- Every HVAC system and plumbing fixture comes with manufacturer guidelines for maintenance and care.
- Ignoring these recommendations can lead to inefficiency, voided warranties, and premature system failure.
2. Schedule Regular Professional Inspections
- Annual HVAC tune-ups and plumbing inspections can catch issues before they escalate.
- Professional HVAC technicians can assess system performance and recommend necessary repairs or upgrades.
3. Invest in Energy-Efficient Upgrades
- High-efficiency HVAC units and plumbing fixtures reduce energy and water waste.
- Smart thermostats, water-saving faucets, and modern insulation improve home efficiency and lower utility bills.
