620. Cold Air Before Heating | #AskDerekCole Episode 58
28 Jan 2026 · 10 min
Derek explains why older heating systems blow cold air at startup, a problem Carrier addressed with Comfort Heat about 12 years ago. Electric heat feels cooler than gas because it runs at lower temperatures. He also covers why installers pull permits, how to reduce compressor noise, and answers a personal question about five possessions.

Hey, on this episode, I talk about cold air coming out of your vents. I talk about your unit being too loud, and I'm not sure what that one was.
Inspections.
You ask your comfort and energy questions and they get answered. This is the Ask Derrick Cole Show. Hey, this is Derrick Cole. Welcome to the Ask Derrick Cole show in episode 50. 58. Yes, 58. It's been a beautiful couple days. Sunshine, no rain, little chilly. I'm really excited. The fact that I had to start my car early on Monday morning, I was really excited about it. I was like, yeah, a little bit of frost. So if you need us, you know where to find us. All right, let's get into it.
When I turn on my heat, why do I have cold air that comes through my vents first?
Yeah, that's a good question. The reason, probably, I want to say 12, 13 years ago, they came up with some technology to fix this problem. But if you have an older system, it doesn't know that the air is not warm when it starts up the heat, so it's going to start blowing it out. So the problem you'll have is obviously that's colder air hadn't warmed up yet. Therefore, you'll be feeling cool air instead of warm air. Now, probably 12, 13 years ago, Carry came out with what they called comfort heat. And all the new systems have it today. It's basically, it knows when it's ready to blow out warm air, so you don't get that cool blast and then the warm air come behind it. So that's why you're having that problem. Another reason you could be having that problem is, and this is why we talk about going from gas to electric. Heat is always a problem for people who are used to gassy because electric heat is 95, 100 degrees at the grill, your body is 98 degrees. So when you put your hand over it, of course it's going to feel a little cool because it's lower than you are. So if it's 96, 97, 98, you're, like, kind of cool. Well, your hand is 98 degrees. So, yeah, it is gonna feel cool, whereas gassy, you know, you're looking at 110, 130 degrees. This is why we talk about going from gas to electric is a problem. Especially the older people. Not so much the younger generation, but the older people are used to the gas, the oil, that warm, hot heat coming out of the grill. Whereas now you have electric heat coming out and it's 95, 100 degrees. You know, there's a big difference between 100 degrees and 120 for you when you feel it, because again, you're 98 degrees. So one's going to feel coolish, one's going to feel really hot. So that could be happening there. I have a feeling you have an older system and it doesn't have this comfort technology in it. So it's blowing out the cold air before it gets hot. Now they did make a product I want to say the name of was Comfort Guardian or Guardian. Anyway, it was an accessory you could put with these older systems to basically warm the air. So you want to get a cool blast. But of course, nowadays all the newer systems have it. Carrier came up with it 12, 14 years ago called Comfort Heat to make you more comfortable. And that was a long answer to that very small question.
Why does my unit need to be inspected by the town or county I live in? After installation.
We pull permits on every install we do because that is what the state law requires for us to do. And if you read your insurance policy, it's going to be what they require you to do. They don't want anybody working on your house that is an unlicensed contractor and then not getting inspected by the code enforcement department of that city or state, county, whatever you have. So it's really about safety too. I mean, yes, that has to be done. But then again, yes, we have been installing stuff for 60 plus years. But you want to make sure it's up to code, is up to energy standards, it's done correctly. You have a third set of eyes looking at a third party looking at it and saying, yes, it's good to go or no, you need to do this and this to bring it to code. Because a lot of code things are really energy and safety items that need to be paid. And hey, we're not perfect. We make mistakes. We got to go back and fix things every now and then. We try not to. But me and this company, you always want a third party to come behind you and look at it to make sure it's done right. And two, if anything were to happen and your homeowners insurance said, hey, who's working your house? It was this contractor, he got this permit, it was inspected here, we're good to go. So there's no reason not to play pay any kind of claim that would come up in that situation. But it has to be done, it's the right thing to do and we want it done because it is a third party looking at our work saying, okay, because you as the homeowner going to protect you because you as a homeowner is paying for the service. But then again, did they install it correctly? Did they install it the way it should be installed in 2015, 2016? And that's where they come in.
We often entertain people outside, but when our unit comes on, it is very loud. Is there anything we can do to help this?
A lot of the basic value systems have a louder than normal compressor. Now when you go to a higher end product, they put around that compressor, what they call a compressor blanket, to actually stop some of that sound from getting out. So you can install a compressor blanket on that unit to make it a little quieter. So that's probably what I would do in that situation if you don't want to turn off and you don't want to be uncomfortable inside even though you're outside. So I'm not really sure the whole dynamics here, but compressor blanket will quiet it down. That is a guarantee. And two, like at the high school, units start making a lot of noise sounds like rocks are in the compressor. Like when it comes on, like, okay, we probably have a problem. So if it's really loud and sounds like a grinding noise, then get it checked out to make sure everything's fine. If it's normal operation is as loud, then get a compressor blanket, get your contractor to install that and it will quiet it down a little bit. But the higher end products, the 16, 18, 20 Sears, they have this, they have a sound blanket to prevent this noise so much from happening.
If you could only take five possessions with you, what would they be?
We're not talking about family as possessions, right?
No, you can keep your family for better or worse.
5 possessions I would keep. Huh. Probably go with the phone as number one. I'm getting a bunch of hearts here on periscope. Keep the phone. Phone would be one. I would say. I was going to say Bible, but the bible is in my phone. So that's going to be just fine. Probably the Xbox and the tv. That would be three God to play the Xbox on. I don't know. Does a power source count as. I don't, I don't know.
I mean we'll just go on the assumption that there's power source.
Okay. There's plenty of power. So got phone, Xbox, tv, G's to one car. Need a car to leave.
Only five possessions.
Airplane.
An airplane?
Yeah. If it came down to it, and I've told you before, I want to be a pilot. If it came down to it, I would try to fly that plane with no training whatsoever and see what happens.
I know. You pull this.
I watched enough movies.
I have an Xbox. I played the fight. See me later. I know what's going on.
No offense.
I'm not hopping on.
We'll take the next one.
There is no next one. We all have to leave now.
We'll be on the plane right behind you.
All right, so it's episode 58. Make sure you hashtag askdericole for all your home energy and flight questions. You can get them answered right here.
