Did you know that it is advised to change the batteries in the smoke alarm every year? I must disclose that I don’t change those batteries frequently, instead I change them when the alarms start to chirp indicating that the batteries are low.
That is with any component or even my car, I change the batteries when I know they are low or after they have died.
There was one incident where the batteries on my control unit died & at first, I thought I was having a serious issue with my central air unit. I was renting a house & didn’t know that the control unit used batteries. It was an older Heating, Ventilation & A/C unit, & the control unit was digital, despite the fact that I could tell it was dated as well. At first, I noticed that the air had become irregular, however when I turned off the control unit & turned it back on, the air conditioner returned to normal. This happened for a couple of mornings, & that is when I thought there was a major issue with the Heating, Ventilation & A/C unit. I almost called my building owner to let him know that I needed an Heating, Ventilation & A/C worker, however after some investigation, I noticed that the numbers on the digital screen of the control unit were fading. It was at that moment that I realized that my control unit used batteries. I figured out how to remove the control unit from the wall, & I opened the back panel & replaced the batteries. After that incident, I changed the batteries in the control unit once per year to guarantee that my Heating, Ventilation & A/C unit functioned regularly & to also avoid spending money on unnecessary service calls, perhaps I should do the same & change the batteries on my smoke detector yearly as they advised us to do.
