Derek Cole answers questions about ceiling fan direction for heating and cooling, investigating bleach-like odors in your home, why your heat smells like burning on first use, and when to call the gas company about raw gas smells.
Questions this episode answers
Downflow/reverse to push warm air from the ceiling back into the living space.
Opposite (upflow) to help move rising hot air out of the occupied zone; primary effect is wind-chill on people, not cooling the room itself.
Possible sources include basement sources migrating upward (speaker cites 'over 60% of indoor air comes from under the house'), cleaning supplies or stored chemicals; running the AC to dehumidify and checking the basement/storage is recommended.
Heat strips and backup heating elements gather dust when unused; the first activation burns off that dust, producing a transient burning smell.
Do not ignore it; call your gas company or HVAC service immediately. Ensure a carbon monoxide (CO) detector is installed for safety.
Chapters
Hey, on this episode we talk about a bleach smell in your unit. Which direction are my fans supposed to be going and should I have a burning smell when my heat comes on? You ask your comfort and energy questions and they get answered. This is the Ask Derrick Cole Show. Hey, this is Derek Cole and this is episode 50 of the Ask Derrick Cole show answering our home and energy questions. And yes, we are back. The rain has stopped, sun shining, took a boat to get here, but we are here.
So I feel like you need like 50 blinking.
Yeah, we got 50. Can we get like a 50 logo up here somewhere? 50 logo. So we are 50 in and we still have questions, which is fine because that's what we're here for. So, hashtag askdericcole. Any question on Facebook, Twitter, Instagram, Snapchat, Twitter, I said Twitter, Tumblr, FIMO, YouTube, whatever you want to use, we got it. Alright, so let's get into the show.
Does changing the direction of my ceiling fan help anything?
It does. You're supposed to have it one way on air conditioning or when it's hot outside and downflow on heating. The reason is because heat rises. So in the fall and the winter, when it's cold, you want obviously the warm air to come back down to living space. So that's why you have a reverse function on that fan because then it pushes that hot air back down just to rise back up again. So opposite way, in the cooling season, you want the hot air out of the house, so it's blowing it up, taking the hot air going up, bring the hot air going down. So yes, it does make a difference. You do need to pay attention. It's a little switch, right? Which way is it going? Which way is it going? So yeah, it does make a difference. But just remember, fans, cool people, not rooms. So if you're not in the room, there's no reason to have the fan on. The fan gives you a wind chill effect. Or in this case in the wintertime, I don't know, like a desert effect. I don't know, I'm not sure. But I'm saying that say this. Don't leave the fan on when you're not in the room because it's doing nothing for the room or for anything but have the fan on. So yes, it does make a difference.
I keep smelling a bleach smell in two back bedrooms of our home. We have a whole house ac. Could this be the source of the smell? The home does have a basement.
I don't know. That's one of them deals that I would have to check out or somebody needs to check out, see where the smell is coming from. Now, you said basement. So something could be in the basement that you have that's causing that smell. Because I don't hold me to this, but believe studies have shown that over 60% of the indoor air comes from under the house. So it's obviously migrating up from the basement. So that could be one of the problems. So I would check that out first, see what's in the basement, if there's rooms, to make sure something isn't coming up into the space that you're smelling. But, yeah, that is kind of weird. So probably check that out. But it's not caused by your ac. I mean, it's not. It's not blowing any kind of Clorox smell into the environment. If the unit was just cleaned or just maintenance, maybe you'll get that smell. But, I mean, that should go away in a few days or a few cycles, depending on the weather. Now, with this weather, we've had it recently. Your house is probably getting a little musty kind of smelling. Because it hadn't run a whole lot. So what I did when I got back home was turn the AC back on, dehumidify, get rid of some of the smell, and that works. So just remember that when it's kind of in between, like it is this time of year and this season, going to where it's cold in the morning or cooler in the morning and warmer in the afternoon, and then cooler again, Your unit's not gonna be running a whole lot. So, you know, watch that temperature to make sure you're circulating that air. Otherwise, you get that damp, stale kind of a environment. It's just because it's not running, it's not pulling the air in and dehumidifying it. So Clorox. Not really sure what's going on there. I would. Since you said basement, I would check basement to see what's in that environment. If you have any kind of cleaning supplies, make sure everything's where it should be. If you read the instructions on cleaning supplies, they do want you to crack a window whenever you use them. A lot of people don't know that. That's why the products we put in the home is all natural products. It's not like a bleach or anything like that. People who are sensitive to it can be affected by it. So check all that. And if you still have a smell, get it checked Personal use this one.
We've actually had, like, three calls on that I've personally answered the phone for besides Carolina.
Hey, this next question, we have had three phone calls about it in just like yesterday. Oh, like in one day.
Okay. Why is it that you smell something burning when you turn your heat on for the first time, but not after that?
So what that is is. I'm assuming these folks have heat pumps. What happens is with your heat and your strip heat coming on as backup heat over the long summer, they're not used. They gather dust. So on that first time it's used, it's really burning the dust off. If you have a maintenance done, if it's done in this, in the springtime, you know, middle summer, you'll get that more often. As we're doing maintenances now where it's cooler, of course, we're activating that, you know, heat strip to make sure it is working. But again, if you had that maintenance in the summertime is probably gonna have that smell this time of year. So it's just. It's just the dust and stuff burning off. There's nothing to be alarmed about. It does kind of smell like a electrical burning smell, and that's the dust. So it's nothing to be alarmed about.
Maybe you should address too, because I had this phone call the other day. The difference between like that kind of smell and this lady called in and said, I just turned my heat on for the first time, but now it smells like gas.
Yeah. You shouldn't be having a rol. Gas smell. Yeah. So with that, you could have a gas pressure issue or a gas line issue. A lot of units we go to, we do have to adjust the pressure every year, and depending on if it's lp, if they refilled the tank, if there's somewhere in a gas line during the summer, maybe a rock hit something and did a little thing. So, yeah, you shouldn't be having a kind of a raw gas smell when it comes on. I would. I would call the gas company or your heating and air company. Just check it out. Because this. That's two different kind of smells. I mean, one's a dust kind of electrical burning smell on a heat pump, and one's just raw gas. And that's. That's very dangerous. So you don't want to do that. And again, I'll say it because it's very important with any gas appliance, you should have a CO detector in your home. You want to make sure. Because LP or gas in general, they put that smell in there. I mean, it's not natural, you know, rotten egg smell. They put it in there for a reason. So you can smell it, detect it. But with co, when it leaks out, or if you got a hold the heat exchanger or whatever, you know, that's. You're not going to see or smell it. So that's why you need a detector to make sure you're safe and your family is safe, because it's something that you can't smell. So. Yeah. And I think RCA detectors also detect natural gas when they come in. So again, you shouldn't be having. You shouldn't have a raw gas smell. So bad smell. Electrical burning heat strips for the first time of year. That's okay. That's gonna happen. Raw gas, not okay. You need to call somebody. That's it. That's episode 50. We're in the 50s now. That means the next was 51 and then 50. Okay. So if you have any questions, hashtag them AskDerrick Cole. We'll get them on the show. I appreciate the sharing and everything on Instagram and Facebook and keep the questions coming. We'd love to have him on the show. By.
