thanks! it ended up being i tried using too high a quality of a filter than my AC could pull though. I switched it back down to a lower quality and the thermostat started to drop almost right away

I learn something every time. As a kid, my parents would have me close different vents and open others in summer and winter. I have always believed and even recommended to friends to do the same. Who knew... a professional I guess!

Meanwhile I was over here doing everything i could to figure out how to stop it from running constantly thinking something was wrong 🤦🏻‍♂️

Thank you for this information, I was panicking about why my ac unit outside was constantly running the past 3 days almost nonstop since we got 90° to 103° days and staying at 74° to 76° for the inside temperature while the set point is 73°f, so I now know my ac unit is in an efficient mode to save on the life of the AC unit and energy cost.

I always wondered what was "wrong" with my AC, since we keep it set at 68, but in the middle of summer, it'll frequently creep up to 70-74 if it's REALLY hot outside. I guess the system was probably designed to that 70-74 range you mentioned. I haven't heard of this before from any of the other hundreds of AC videos I've seen, so thank you for spreading the info! :)

For sure! Thanks for watching… When we retrofit a system and do a quote we always ask what temp they like to set things at because I’ve had people say 65 and when we hear that we almost always look at adding a ductless somewhere or VRV unit so that it keeps up!

I have a geothermal system and it works fantastic for heating and cooling.

Well explained, thanks

Right on my pleasure! Glad you enjoyed the explanation!

I remember a few years ago it hit 108 degrees here in Portland, Oregon and my system was not keeping up. i called the A/C people and asked about it. Their answer is simply that they don't design systems in Portland for such abnormal heats. When I later had to replace my 15 year old condenser, I asked them to increase the size from 30K to 36k BTU. Good thing to, as a couple years later we hit a staggering 116 all time record heat and my house stayed reasonably comfortable.

Yeah that sounds right the design temps vary by region but if your ductwork could handle the increase in sizing (which it sounds like it can because it’s not icing) then it sounds like it was a good move 😁

I had the opposite, an undersized system. I figured when it was in the mid 90s to 100s outside, not getting below 78 indoors was normal. My unit was close to 16 years old so I wanted to replace it before it died on a hot Texas day so I did early this year. Lo and behold, all bids I received told me my 3.5 ton was way too small for my sq ft. of 2699. They did some duct mods and now it cools nicely.

I have the same problem. The house was added onto and when the central AC was replaced, it was replaced with the same size and not upsized. Went from like 1700 sq ft to 2300. Still a 3.5 ton unit. The air flow is also messed up. Shut air off going to addition, put a window unit in there. Had to put in dampers to balance the rest. Had a ton of air dumping into one bedroom. Still have a lot of work to do. Poor airflow to two back bedrooms. Duct is coming off the back of the plenum. Someone told me that will cause poor airflow. Need to add a vent going to middle bathroom. Gets hot in there. Lol old houses.

There is another consideration in system sizing in very humid areas: If a system is sized too big, it will bring down the temperature before it has reduced the humidity in the house, resulting in the homeowners feeling cool and clammy.

This is true!

Our downstairs A/C seems to be a decent size. No it does not run 24/7 but nor does it short-cycle. We have a separate attic system for the 2nd floor. It’s a smaller system. It’ll maintain our set point of 75 until the outside air rises to about 85 and then by 90 it can longer keep up. Putting the air handler and duct work in the attic does it no favors. 83 yr old house and the sun bakes the roof. We have R38 in the attic - not too bad for TN - none of which really matters in summertime. I’m also of the opinion that the return isn’t sufficient and am thinking of perhaps adding an additional return to it if I can.

Really helpful! I just turned my fan onto On instead of AUTO, hoping that makes a difference. One end of my home is warmer than the other. I also have my thermostat in a hallway, I’ll need to move it to the living room. Thanks again 😊

@@USCG.Brennan It depends on your geographic location. Generally if you are in a high humidity area like southern U.S than that is a very bad idea. if your air handler/furnace blower is running continuously independent of A/C setpoint you will be drawing in hot, humid air through doors ,windows etc. without it being conditioned. As in you are bringing in unfavorable air when your A/C condenser is not operating so introducing higher load than designed for and will cause many issues. TLDR: Leave fan on auto

Interesting. My problem with my A/C is the second floor works great, but the first floor doesn't feel like it is getting much air. The ducts are open on the first floor yet it doesn't feel like any air is coming through them while upstairs it most certainly is. The air isn't naturally trickling down either so while I have the upstairs set to 70, the first floor is 74-75, and the basement is even warmer at 75-77. I don't have central heating but heat rises just fine in the house. I also have electric baseboards to compensate so this isn't an issue I am seeing. I feel like something is jammed in the ducts or something.

@TheHVACDopeShow

Жыл бұрын

This is very strange I’ve never heard of a basement being warmer than the rest of the house when the AC is running. I would look at ducting. Sounds like an issue with airflow balancing or maybe runs being disconnected, I’ve never ran into this lol for what that’s worth… sounds like ducts aren’t connected or dampers are shut or something is off with the design

If I close a vent, I also shut the room door off from the rest of the house. That does help significantly.

@TheHVACDopeShow

Жыл бұрын

Right on if it’s not icing then it’s probably fine… It still restricts total airflow so if you have too many vents shut to the point it ices us and doesn’t keep up it will actually be counterproductive. We advise people to keep as many vents open as possible. In systems with undersized ductwork even 1 or 2 closed vents out of 10 or 12 can make a difference to cause things to ice.

Any recommendations on a replacement system in Las Vegas? Currently have two 25 year old Carrier furnaces a 17 year old york single stage condenser and an 11 year old goodman condenser single stage. When the time comes to replace does it make sense to replace with single stage? I’ve seen your videos about the Daikin Fit and also seen video about Bosch ids 2.0. Not sure how heat pumps would work in the desert tho. Thanks for the advice.

@TheHVACDopeShow

Жыл бұрын

They work great but I would check with a local contractor on the Daikin fit and in Vegas get a higher efficient inverter system you’ll be much happier you did… your AC runs constantly there the savings will definitely pay off over time. I’ve heard the Daikin fits do well but in high ambient above 110/115 there can be issues with humidity during monsoon season (in phoenix) above 3.5 ton systems only. So just check with a local contractor that sells Daikin because they’ll have the inside scoop on local systems, but an inverter system is definitely worth it in vegas and will keep up fine in the winter too.

It just kills me that I pay natural gas surge prices in Colorado when Texas is falling apart because the utilities don’t cold proof their gas pipelines and generators. I’m with you on heat pumps to free me from Texas’ energy failures.

Yeah Texas also has deregulated energy which I think has made things cheaper but also kind of the Wild West in certain respects

So, if your system is running all day and keeping things set to where it's designed, then I take it to mean that just like a car with cruise control engaged, it runs smoothly. If it's running like it's driving in New York City, well, stop & go driving is no fun. Thanks for a good video. I'm gonna share it with a few folks so they check their systems against the points you mentioned.

Awesome sounds good and glad you enjoyed it and found it helpful!

I wish you had a branch in Miami...no one here wants to take the time to conduct such a comprehensive analysis, and/or they simply aren't sufficiently knowledgeable to do it. I had a "reputable" Trane authorized company come out to give me an estimate on installing a new, additional, split system to my house as the two existing 5 ton systems are unable to keep the temperature from rising during severe temp days in the summer... and they told me that I had to hire a GC to do a load calculation to determine the size of the new system...I mean, shouldn't a good AC company be able to do that? Certainly sounds like your company can...

How bad is it if I don’t have a cold air return? My house does not have one and my ac can’t ever cool my house down.

@TheHVACDopeShow

Жыл бұрын

What do you mean doesn’t have a return? That’s not possible the system will just ice and not run and not be able to circulate air. You definitely need enough return air otherwise it won’t circulate air without a return… did a fix and flipper cover them up or something ?

If you only have 1 return air duct in a house it's a Red Flag! Make sure you have a HVAC tech check your static pressure! If the total static is over 0.50 you need to fix the size of your ductwork! In my area over half the homes only have a single undersized return air duct. This is often giving you half the airflow that your system is designed to move.

@TheHVACDopeShow

Agreed! The builders don’t have to service the equipment otherwise they’d add more return air

I keep thinking there’s something wrong with my system, and I think that there must be because I have my setpoint at 77 and by the 3 o’clock hour the machine is running constantly, and the temperature will be upwards of 81. The machine itself sits in direct sunlight for 90% of the day and the outside temperature in the summer months gets to 105+. It seems to me that the machine is not able to keep up, but I don’t understand what the issue is.

@TheHVACDopeShow

Has it ever kept up? I would check the basics like air filter / open all the vents etc… it could be refrigerant charge but I always check airflow and basics first. Especially if it was working at one point and just recently stopped… if it’s never worked properly from day 1 it could be a sizing issue / design issue.

I just had a new unit put in(3ton) in a 1200 sqft house same as the old one but it blows way harder. I have so much positive pressure its blowing the pet door going into the garage open Now. I added weight to the door, made sure all vents were open, and even remove the filter to make sure it wasn't too restricted. It still has too much pressure. Any ideas?

I knew when they were installing my new central air system in my 101 yr old house that it would never actually be comfortable inside. Mainly because they had not even invented insulation when the house was built!!! (Nor was there any indoor plumbing!) This is in a moderate southeastern normal residential neighborhood. We actually set the thermostat on 82 downstairs in hot weather, and a miserable 85 upstairs, because otherwise they would both run day and night and never stop or catch up. It would be impossible to upgrade the entire house to install insulation, because it would be far more cost effective to just bulldoze the house and rebuild... believe it or not. So, other than simple things like checking filters and cleaning condensers, there are no real solutions here. Oh, incidentally, during winter we set the thermostat on a cool 61 for "heat"! Can't raise that to a comfort level for the same reason. One more thing: if I were to blow in insulation, would have to ensure this is not creating a fire hazard around the 100 yr old knob-and-tube wiring! Main lesson: Think twice before buying an OLD house!!!

@TheHVACDopeShow

I would verify its sized properly for the load and ductwork. A simple “cheap” insulation is blow in… you can get the machine rental at Home Depot for free if you buy enough insulation, it’s like maybe $500 to insulate a 1200’ attic space and that will usually make a huge difference if you have no insulation whatsoever

@@TheHVACDopeShow Thank you for the reply. I have attic landing insulation, that's not really the problem. It is a large old house with plaster on lath walls downstairs, and wood drafty beadboard walls upstairs, no insulation. By creating countless DOZENS of holes in these walls to blow in insulation, it could help some, but would then create a virtual nightmare to repair all those plaster and beadboard holes throughout 11 large rooms. Plus, the old style construction used angled members some places behind the walls, which would prevent blown in insulation from filling the voids. The house would be absurdly impossible with holes every 16 inches in 11 large rooms, just about impossible to properly repair. Not easy like drywall is.
