HVAC Myths Debunked

HVAC Myths Debunked

There are many myths and misconceptions surrounding HVAC systems that can lead to confusion and costly mistakes. In this blog post, we’ll debunk some of the most common HVAC myths, so you can make informed decisions about your home’s heating and cooling systems.

Myth #1: Closing Vents in Unused Rooms Will Save Energy

Many people believe that closing vents in unused rooms will save energy and reduce their energy bills. However, this is a myth. Closing vents can actually cause your HVAC system to work harder and less efficiently, as it can create imbalances in your home’s airflow. This can lead to higher energy bills and even damage to your HVAC system.

Myth #2: Bigger HVAC Systems Are Always Better

Many people believe that bigger HVAC systems are always better, as they will heat or cool their home faster and more efficiently. However, this is also a myth. A system that’s too big for your home can lead to short cycling, which means the system turns on and off more frequently than it should. This can lead to higher energy bills, more wear and tear on your system, and less comfort in your home.

Myth #3: Turning Up the Thermostat Will Heat or Cool Your Home Faster

Many people believe that turning up the thermostat will heat or cool their home faster. However, this is not true. Your HVAC system will heat or cool your home at the same rate, regardless of how high you set the thermostat. Turning up the thermostat too high can lead to overheating or overcooling, which can waste energy and lead to discomfort in your home.

Myth #4: You Don’t Need Regular HVAC Maintenance

Many people believe that HVAC systems don’t need regular maintenance, as they’re built to last. However, this is a dangerous myth. Regular maintenance is essential to keep your system running efficiently, prevent breakdowns, and extend the life of your system. Neglecting maintenance can lead to costly repairs, reduced efficiency, and even safety hazards.

Myth #5: Closing Doors and Windows Will Keep Your Home Cooler or Warmer

Many people believe that closing doors and windows will keep their home cooler or warmer, as it will prevent air from escaping. However, this is not entirely true. Closing doors and windows can restrict airflow, leading to imbalances in your home’s temperature and reduced efficiency. Instead, it’s better to use proper insulation, weatherstripping, and shading to keep your home cool or warm.

Myth #6: A Furnace is the Same as an Air Handler.

An air handler moves the hot or cold air in a forced air system, and a furnace creates and transfers heat. The air handler moves air in and out of the ducts and grates and contains the indoor coil essential to HVAC Systems. A furnace is equipment that generates heat, and all furnaces have a blower fan, similar to an air handler. To put it simply, a furnace creates heat where an air handler does not.

Myth #7: My Technician Should Know About My HVAC System; I Don’t Need to.

While having an understanding HVAC technician who spends a lot of time going over every detail of your system is beneficial, even the best technicians will not know your specific situation better than you. Therefore, the more you know, the better questions you’ll have when it’s time to repair or replace your system and the better choices you’ll make when making any significant HVAC investment.

Myth #8: My Heater or Air Conditioner Uses Less Energy When It Runs Less Frequently.

On days with severe temperatures, equipment will need to operate longer and use more energy than on days with moderate temperatures. But when it comes to the actual equipment, this isn’t true. A variable-speed air conditioner or furnace will frequently run longer than a single-stage or two-stage piece of machinery. Although some variable-speed systems may run at as little as 25% of their capacity, this just means that you’re consuming a small portion of the cost over the longer uptime. In comparison, systems that often turn on and off while they are only operating at 100% of their potential may have somewhat lower uptime overall.

Myth #9: My Energy Expenses Will Always Be Lower With a High-efficiency HVAC System.

This is theoretically accurate, but we can’t always guarantee cost reductions because your savings mostly rely on how frequently you use your furnace or air conditioner. Consider that your thermostat is set at 67 degrees and that you don’t mind the cooler winter months. In comparison to a home that enjoys 78-degree winters, when the furnace will be running continuously, the cost savings in the winter for that home will be much lower.

Climate is another factor that might lead to apparent savings. Yes, a brand-new, energy-efficient furnace will cost less per minute than a furnace that is 20 years old and has a lower efficiency rating. Your actual savings, however, will be negligible if you reside in the southern United States, where the winters are mild. On the cooling side, the same holds.
