HVAC Myths You Might Still Believe
July 21st, 2016 by admin
There are a number of energy saving tips that can reduce your electric bill and help protect the environment. However, sometimes people follow techniques that they think will reduce their energy consumption, but which end up costing them more overall. To stay savvy about your energy use, here are some myths about HVAC that you’ve probably heard, and maybe even follow.
Myth: Turning Your Thermostat Lower Cools Your Home Faster
It may seem reasonable to believe that if you want your home to be 75 degrees, setting your thermostat to 70 degrees will cool it off more quickly (or vice versa in the winter). However, this is not the way HVAC systems work.
HVAC systems have two settings: on or off. If your system is on, it’s cooling the house, and if it’s off, it’s not. To keep your home at the desired temperature, your system simply runs until it reaches that temperature — then turns off.
This means that your air conditioning system doesn’t work any harder if you set it to a lower temperature. In fact, setting your thermostat to a lower temperature, chances are you’ll forget to turn it off and you may end up paying to keep your home cooler than it needs to be.
Myth: Leaving Your Ceiling Fans on While You’re Gone Helps Cool Your Home
Fans can be a great way to keep yourself cool during the summer, but that’s all they keep cool: you. The reason fans feel great is that they cool off your skin, not that they lower the temperature of the air.
While it can feel great to leave the fan on while you’re in the room, leaving them on while you aren’t around doesn’t do much but move the air around — a job that your HVAC system has already taken care of. Save energy by turning your ceiling fans off when you aren’t home.
Myth: Closing Registers in Unoccupied Rooms Saves Energy
Many people are under the impression that it is unnecessary to heat or cool a room if no one is in it. By shutting vents or registers when you leave a room, it is believed that you can save money on your energy bill. Why heat or cool a room you aren’t using?
However, this practice ignores the way that HVAC systems work, and can actually do much more harm than good. If your home has a modern HVAC system, it will try to keep the pressure balanced throughout the house. If one of your rooms is much colder than the others, that room’s low pressure will draw heat from the rest of the house, which will make your whole house feel colder.
Additionally, this practice can hurt your ducts as well. Closing your registers can actually cause your ducts to leak, making your HVAC system more inefficient.
Myth: There’s No Reason to Have Your System Checked Unless You Notice a Problem
Your HVAC system is an easy thing to forget about when it’s running properly. However, when things can go wrong very quickly with no visible cause, it’s hard to ignore. Issues that seem unexpected or sudden to you likely have underlying causes that have been going on for quite some time.
Scheduling routine filter replacements and cleaning the condensate line and pumps are easy steps you can take to ensure your HVAC system runs smoothly. Having an expert check that all the parts of your system are running properly can save you from having to make expensive repairs and from the discomfort that comes from a malfunctioning HVAC system.
