🔥❄️ Why Does One Room Feels Hotter or Colder Than The Other Rooms in My House? · Shafer Heating and Cooling Service Repair Podcast

• 0:01
  We hear this all the time, hot and cold spots in the house. What does that mean?
• 0:07
  Well, the questions come in.
• 0:09
  Why is one of my rooms hotter or colder than the other?
• 0:15
  So I guess this person has a problem in the summer and the winter is my guess,
• 0:18
  probably with a specific room.
• 0:19
  So we hear about it, hot and cold spots. One room is hotter in the summer than
• 0:25
  the rest and colder in the winter than the rest. What could be going on there?
• 0:30
  Yeah so it could be a few different things um right now
• 0:33
  if it's in uh summertime um and
• 0:37
  really wintertime too for that matter it's it's if it's the same room it
• 0:39
  could be a couple different things sometimes it's opposite rooms but first thing
• 0:42
  i want to look at is is just overall once again the simple things i like to
• 0:46
  keep things simple as are the registers all opened uh but not even just that
• 0:50
  are they adjusted properly so all all the way open isn't always uh the the correct
• 0:55
  or the best option right because those registers that's why your suppliers have dampers on them,
• 1:00
  you can adjust them, where returns don't. So we always want free return coming back.
• 1:04
  The supplies can be adjusted to regulate the final amount of errors coming into a room.
• 1:09
  Air is lazy. It's like a lot of us, right? A lot of people. It's lazy.
• 1:14
  It takes the path to least resistance.
• 1:16
  And so that air, as it goes down the duct stream, gets farther away from the furnace.
• 1:20
  It gets less and less and less. It's going to leave the first vents possible.
• 1:24
  Oftentimes you'll find registers dampened down a little bit more closer to the
• 1:28
  equipment and opened up a little bit more as they get farther away from the
• 1:30
  equipment to help keep the pressure up.
• 1:32
  Now, a properly designed duct system is going to help eliminate how much those
• 1:37
  have to be adjusted at the actual register. That's just the final point of adjustment.
• 1:41
  So there's one thing is checking the register, making sure they're open,
• 1:44
  free, not covered up and adjusted properly.
• 1:46
  The second thing being is duct sizing is the duct system properly sized.
• 1:51
  One of our guarantees that we give with new systems is a 25% utility savings guarantee.
• 1:56
  One of the biggest reasons, there's a couple of things, but one of the biggest
• 1:59
  reasons we're able to do that is because of airflow and because of proper duct sizing.
• 2:05
  It's amazing. And if you look at studies that have been done across the country,
• 2:10
  how many air duct systems are improperly sized?
• 2:13
  As a matter of fact, I think it's over 70% of systems across the U.S.
• 2:16
  Never reach 75% of capacity.
• 2:18
  I may be off. I'm pretty sure that's what the study shows, which is amazing.
• 2:22
  And that comes down to system sizing. So doing proper manual J-low calcs on
• 2:26
  the home to get the proper size system, but as well as them properly sizing
• 2:30
  the duct system for that space.
• 2:33
  And so that's another thing that comes into play. So then, of course,
• 2:37
  cold spots can also be affected by overall efficiency of the system.
• 2:42
  We talk a lot about, you know, on this show that ties to so many different things,
• 2:45
  the cleanness of the system, filtration, things like that.
• 2:48
  But those are going to be a couple of things that can definitely cause that.
• 2:51
  I'm sure you've also seen something very simple. Um, we were up in your attic
• 2:55
  and for some reason there's no insulation over that room.
• 2:58
  Yeah, absolutely. It could be as simple as that.
• 3:01
  If someone's done something at one point, they had to retro an area,
• 3:05
  reflect whatever, who knows what, right?
• 3:07
  It could be a list of things, but yeah, just no insulation or poor insulation.
• 3:11
  Another one too, we talked about duct sizing, but it's also air leakage.
• 3:14
  And so a lot of duct systems have a really lot of, or a lot of air,
• 3:19
  I'll get it, a lot of air leakage in the system.
• 3:22
  So around the joints, around the boots, around the takeoffs,
• 3:26
  whether the flex duck hooks up to the takeoff, and if it's sheet metal duck,
• 3:29
  all the joints and rivets and screws and things, it's amazing you add all it
• 3:33
  up, how many square inches of air loss there is on a duck system.
• 3:36
  And so once again, it gets farther away from the system. Now we have more air
• 3:39
  mixing from the crawl spaces and attics and wall spaces and different things.
• 3:43
  We're going to hurt the comfort of a given room and or air even delivered there.
• 3:48
  It's a science. It's experience.
• 3:52
  You guys know what you're doing at Schaefer Heating and Cooling. Um...
• 3:57
  You know, the experience thing, let me touch upon that. No matter how much you're
• 4:01
  trained in the classroom, there's just so much you learn over time.
• 4:06
  In an attic, in a basement, in a crawl space, in a garage, you know, on someone's property.
• 4:16
  And it's, you know, it's all collective. You know, it kind of reminds me of AI today, like ChatGPT.
• 4:21
  It alone, I don't think is smart. It has access to all this information across
• 4:28
  the internet, and it processes it and brings it together for a result.
• 4:32
  And I think that's how it is with you guys. You have highly trained and experienced
• 4:36
  technicians, don't you?
• 4:38
  Absolutely. So back to training, yes, that's extremely important.
• 4:42
  Every single one of our team members, myself included, go through over 250 hours
• 4:45
  of training minimum per year.
• 4:47
  And so that's ongoing forever. day one, or you've been here for 20 years,
• 4:52
  we're always going to continue to train and train and train.
• 4:55
  But also too, this year we celebrate our 40 years.
• 4:58
  So we also have 40 years as an organization of experience, you know,
• 5:02
  seeing all these different scenarios and going through and learning and constantly
• 5:06
  adapting to be able to provide that best service possible.
• 5:11
  So yes, experience and training, you put the two together.
• 5:14
  That's what you call a wow experience.
• 5:17
  Unbeatable congratulations on your 40th anniversary that's
• 5:21
  fantastic that is thank you that is phenomenal phenomenal okay thank you very
• 5:27
  much nathan i appreciate it all of nathan's information is located in the show
• 5:32
  notes there's no excuse not to reach out to nathan and his team at shafer thank
• 5:37
