With so many opinions out there, how do you sort out the truth from the myths?Here are some common myths about your HVAC unit:
1. Your HVAC unit doesn't need to be checked unless there's a problem.
Scheduling regular HVAC maintenance can help
you find the problem before it becomes a problem so you won't be stuck in
the cold without heat or in the heat without A/C.
2. Closing off vents will save energy.
In reality, your system (if you have a modern
HVAC unit) will balance the pressure load through other open vents and not
reduce the amount of air pushed out. Blocking a vent could also throw your
system out of balance and force your system to work harder.
3. A fan is like your A/C.
Fans are designed to circulate air in the
room, not cool the room like A/C. A fan will blow cool air on you but it will
not drop the temperature in a room if left on.
4. Having your A/C on for short periods of time will save energy.
Your unit uses the most energy in the first
3-5 minutes of starting up. Turning it on and off can actually increase
the amount of energy used. Run it for 40-50 minutes for the best
efficiency.
5. Cranking the thermostat will cool/warm your home faster.
The temperature you set your thermostat to has
no correlation to how fast your unit
will heat or cool your home. You unit will use the same power level no
matter what temperature you have it set to.
