![Air Conditioner Not Cooling Enough [2 Simple Checks to Do Yourself]](/img/n.gif)
A factor I’ve discovered that greatly helps HVACs. A ceiling fan. But running on low not high. I think inclination is to set the ceiling fan on high. I find that pushes cold air to the corners of the room, not achieving circulation. Low speeds gently circulates the cold air. I have mini split ceiling units. One of my rooms had the AC set to 63. The reason for the low setting was it was hot. But I noticed the ceiling fan was on high and that despite running for over 30 mins, the room temp never went below 70. I raised the AC Temp to 66, lowered the ceiling fan to low. Within 5 mins temp started dropping/cooling. Within 30 mins room was, and remained at 66.
I’m in FL, bought an 86’ 3 years ago and the ac was 5 years old. Haven’t had it serviced but I do clean the condenser and change the filter every 30 days. Over the last couple months my ac just runs allllll day. Temp is set at 76 but the thermostat reads 77-78 though the day. Use to be able to set it at 74 and it would hit that not problem
For the first time in awhile our Houston area humidity dropped down to 35% and we had to adjust thermostats for comfort. Save on electric bill. JG you're always spot on!
Thanks for sharing!
Living in central GA it's just plain HOT and humid in the summer. I run a window unit as well. it helps alot with the central AC not having to work as hard.
I do the same here in Texas. We had the hottest and driest summer on record here in Austin. My HVAC doesn't work near as hard with a window unit running 24/7 to help out.
Have technician come out 1 a year ,,don't have to worry or doing anything else
Great video. I really appreciate your desire to help people understand the basics instead of just trying to sell them something. I wish you and your business great success.
I live in a 2 bedroom apartment, going on 6 months living here. For the light bill and it was $438. Had the maintenance guy come and check it out bc it keeps making a metal thumping or clanking sound when it kicks off and on. He said is normal for it to make that sound and that it's a new unit that's up in the attic. Excuse me, I've lived in many apartments and I've never heard an ac unit do that. He told me to just shut off during tye day and get black out curtains and have them closed all day and night. Uh... wait what? You wave me to live in the dark and have my ac off??? Ok, i wanted to see what would happen. It's midnight and it's 79 outside. Turned tge ac on at 6 and set it for 70. Temp inside read 81. It took 7 HOURS for it to go 81 to 76, 7 HOURS and it isn't at 70 so I set it for 73, still at 76 and still running!!! This can't be normal or is it??? I've complained about this and they keep telling me it's normal and nothings wrong with it. These apartments are 20 years old. My friends who live in houses say that's crazy bc their houses are bigger then my apartment and their light bill doesn't go past $260. I'm thinking about calling the city inspector. Any advice or thoughts on why the ac unit is taking hours to get to 70 or 73? Help, someone please. Ac still running trying to get to 73 and i don't know it'll be at when i wake up.
Having this exact same problem. At first when I move in the AC put in work, but now it struggles to even bring it down a couple of degrees. I live on the top floor so I would understand a bit lack of performance but its crazy now. The maintenence people said the inside coils were dirty but that did nothing. I'm on the same boat as you are. I might just call a tech to check it out and tell me whats wrong and give that info to the leasing management.
@@pablosibaja485 Well, I recently figured something out that worked. I don't know if you have any ceiling fans in your apartment like I do but incase you do I'm going to pass this information to you since it helped me. Since I was told heat rises and since I'm on the second floor we get the brunt of it. If your ceiling fans rotate different directions this will help, if it only rotates one direction it won't work. Most ceiling fans have a switch at the neck of the ceiling fan. That's to switch directions during the winter months and summer months. The air will either blow down our up towards the ceiling. It's recommended the air blow down during the summer I tried that and that's a huge mistake if you do this your ac will then run 24/7 non stop. Switch it to where the air circulates upward toward the ceiling. Then have your vents slightly downward, not to much just enough to get the air to flow at an angle. If you have a box fan or tower fan have thoughs running also. If one room is cooler then the others have one fan at the doorway of the coldest room, turn the fan on lowest setting blowing out the coldest room. The back of the fan should be facing the coolest room. This is going to circulate the cool air out the room. Once I had the ceiling fans blow upward my ac wasn't working overtime bc now the air was cooling the ceiling. The air will hit your walls spreading the air all over the room and you'll feel it. It stayed at 73 all day and when 2pm rolled around it didn't go to 74 it stayed at 73 but the ac ran nonstop from 2pm to 6 pm then it went back to normal bc it didn't need to cool the apartment. Blackout curtains help also so if you can Blackout all your windows with those curtains you can live the curtains open to which ever room you're in the most and your ac will still remain at your setting temperature. This is what I've been doing and it's working perfectly! Ac is no longer working overtime. If you don't have updated ceiling fans maybe put in a request for one that has the option for the setting to blow down or up. If you do have ceiling fans without the second option ask your apartment manager if they can upgrade or update with one that has the option to blow up or down. You can always ask if you can replace the fan yourself or if maintenance will install it for you. Let them know it's to reduce the cost of the light bill and so there isn't wear and tear on the unit that way it'll last longer and both you and the manager win, win. That's what I just figured out a couple of days ago. Hopefully you have an updated ceiling fan with both those options. Hope this helps. Do keep me posted!
I'd call the city to see if they have laws around AC.
Your unit isn't working properly. A simple inspection will show this. They use temperature guns to see if it's blowing cold enough.
Good luck
Had a J-Calc done, and the recommendation is to upsize all lines and address an aggressive bend at the rear of the home. It’s been over 100 degrees for many days in MS. The system usually works until you get above 92 degrees outside by noon. As the day progresses the interior of the home can ramp up from 74 to 77 degrees on the thermostat, and the unit runs nonstop from noon to 9 pm.
Was quoted 6K, and would rather not finance. I’m thinking about getting a window unit like my grandparents used to until I save up.
That's a shame it was not size correctly from the beginning. So sorry to hear.
Change your filter and get your system serviced. Make sure the tech runs a static pressure test. At least 70% of homes in my area have high static pressure and a 2nd return air duct is almost always needed. High static pressure means bad airflow in the house. Also, in summer keep your home from getting hot by keeping the AC on and running all day long!! Turn it on in the morning, even if everyone is leaving for work. It's a whole lot easier to keep your house at the desired temperature.
Absolutely this. A 2nd return does help. I was recommended this with my hvac tech. I have a system of 2 years and struggled during hot days. My hvac tech did say the refrigerant lines would condensate and did a pressure check. I thought it is strange for a place that is 600sqft needed a 2nd return but turns out he's right
@@Travis66421 For that small of a place they might have only used a 10 or 12 inch return duct and that's not enough airflow. IlThe returns are the start of your system and have to be sized right! Far too many companies never test or explain that there is an airflow problem. I'm glad you got the 2nd return added, it often makes a huge difference.
@@KPHVAC
If im right, the cover for the air duct is 12x12.
This may be the same for the ducting as well. Too small?
@@Travis66421 Yeah that's really small! A small home with a 2 ton system, 24,000 BTU's for AC or a 40,000 BTU furnace, could get buy with a single 16 inch round return duct. The grill should be at least 16 inch by 20 inch. You definitely needed a 2nd return air duct!
@@KPHVACmy until blows cooler in the day but not as cool at night. Any idea why?
like you said my central cooling system never blow cold air blow the 60-64 but i installed mini spilite 2 tons Dakins this summer its not make different for the unit if outside its 108 and inside house is like 85 it is blow 49-50 cool air all the time which its awesome and now i just run my mini spilite unit .
Great video. 1 recommendadtion. That disclaimer at the very end. Should think about putting that at the beginning.
I’m at a loss right now. My ac has a very hard time bringing the temp down. It’s a newer unit and the delta is always around 20 to 22 degrees. But during the day I can’t lower it past 80 and at night I can’t get it below 75 some nights. I just added attic insulation and it’s made a small difference but not much. My windows are brand new double pane. The only other thing I can think of is maybe there’s an air leak.
Use low merv rated filters also make sure you have enough returns.
@@ncvman I have a terrible return filter size. 23.5x17.5 and theblowest I can find is 8. But I believe I found the issue. I believe there’s duct leaks and I got some people coming out to do a duct leak test
We added a mini split this heat In Louisiana is deadly
How’s it working out for u? Added to your bedroom or living room? I’m in south Louisiana (Prairieville) and my wife and I are seriously considering adding a mini split to our master bedroom bc it’s the hottest room in the house and has the weakest airflow.
Yea, heat down here is hell it's like as soon as you step outside your drenched
I have my central heat and air unit in the attic like you were talking about and I'm wondering if the fan that removes the heat turns on and off or just runs constantly. Right now there's just two vent windows on the front and back of the attic.
My local energy company says to keep it at 74 during summer. I have it set to 74, but inside the house is 82. The AC has been running nonstop, and it doesn't get to the set temperature. I've changed the filter not long ago with a new one and still running.
Any thoughts on how to get it 2 set temperature?
Here in Florida we hit 97 (112) the other day. My ac is only about 3-4 years old and it got 84 in my house, even with blackouts.
Thanks for the video. I'd be interested in hearing you discuss the long term benefits and drawbacks of those misters. Seems like it might ease the load on the compressor, possibly extending its life, but have their been corrosion problems?
Great idea. The biggest feedback I've heard is folks with hard water having the buildup on the coils. Requires a little more maintenance keeping the coil clean. Are you considering having one installed?
@@NewHVACGuide I'm interested in the idea. I might try putting one on my own house to see if I can see any difference.
Can you tell me is there any new Installs that is using R22
Interesting thoughts. The misting idea would be a good plan for those in desert heat areas however, depending on the hardness of the local water there, might be best to use distilled water to prevent scale build up on the "fins" etc. Good disclosure to the public about "everything holds heat inside the house" such as the furniture, appliances and other physical items. I always tell folks that its about the same as a hot baked potato out of the oven. Think of it that way...at some point the amount of BTU's or heat they absorb when they turn the temp upward and go to work is way more than they would think and when returning home or when the set back temps turn on again, the A/C has to remove all of that heat before it will cycle normally. Depending on the home age and energy upgrades, leaving the A/C on 24x7 all summer may cost less than going through heat cycles every day. Those who set their temps below 76 in hot weather are simply using maximum A/C and electricity as well so they shouldn't be complaining about power usage.
We have high power rates in our town, 38 cents per kWh ! That's about 5 times higher than most and when its hot outside, we pay through the nose for power that comes from the same places anyone else gets. $675 a month in summer when most are paying $150 (1,800 kWh). But, its not bad enough to warrant an expensive 26 SEER system yet as its only 3 to 4 months a year. Now that the nations Government seems to think banning natural gas is a great idea and using heat pumps in areas that reach 115 in summer and 30 every winter, the cost for energy will easily increase due to the increase in power usage during winter and less efficiency in peak summer and winter times. What a complete cluster Newsom & Biden have made. We have our Government telling us how to heat and cool our own homes.
Yeah. I have a friend in Florida that says they clean the systems with misters more often.
You definitely have to use a water conditioner and de-scaler filtration system when misting the condenser unit. I tried that out here in Colorado and it evaporates it so fast, I had to increase the flow. It say in the sun for half the day and then the timer would turn it off. It wasn't ask effective while shaded obviously. I had to take my side panels off a few times a year to clean off the cottonwood and all the crap it would suck in on the fins. Here we leave our variable speed blower fans circulating 24/7 to keep the air as consistent as possible throughout the house but this is a tri-level, which is a bear to keep cool evenly. We are going to try that spray-in insulation just like this this video in the attic. And I think we might try a ventilator for the evenings and night. We already have an R60 in blown-in cellulose and when the siding is changed, we will fill the walls full of that liquid insulating foam they can pump in. Crossing my fingers! But I was thinking, $675 a month would definitely be reduced with a 26-28 Seer Variable stage with variable speed, surely it would some serious cost savings, no? I guess I do not know what you have now though. I have a 19 seer variable stage / variable speed blower and it replaced a 10 Seer dinosaur. I guess it isn't fair because I got to buy my system at wholesale though. You are exactly right about all that nonsense the government is spewing out about Nat gas, complete nonsense. The ole dummy moved from one fossil fuel to another causing natural gas to go through the roof. Genius move!! Funny part about the world pollution isn't even made by Americans. It is the countries in the Pacific rim and India that pollute like crazy. Not to mention the countries in South America. America is super clean in comparison. China pumps more pollution than they can count every single day. Anyways, Heat pumps have their place but they are worthless where I live and sounds like the same where you are. We are definitely on the same page with Newsom and Biden. The government is even telling us what toilets we can use now! Thank God for the internet shopping! I am all for conservation but Jesus... a man wants his throne!! Which I finally have now!!
@@Balticblue93 Those two story and tri level homes are always uneven. I had one and when I sold it I knew never again would I try to sleep upstairs in the summer and watch TV downstairs in the winter. Heat rises and cold air sinks...I simply cannot compute swimming up the current and going nowhere. The best home for those who need two levels is a basement with ground level living or a one story above. Maximum 10 foot ceilings and no vaulted etc.
Also air infiltration is a huge factor. Not enough insulation leaking windows and doors and like you said attic ventilation all has a huge factor in all this .
I’m in Virginia down 64 from you, and the house envelope is the biggest issue here, but duct work issues will also cause high temps, if the tech is doing his job right and the installer, you don’t need to oversize and add a dehu, the ac will dehumidifi perfectly. If your duct and and ac is setup properly for it
Where in VA are ya? I grew up near Staunton!
It makes me laugh every time I hear dehumidifier on an HVAC system. In Colorado, we had humidifiers to our HVAC systems because we live in the desert and everyone thinks it is all snowy and rainy. 330 days of sunshine and 10% humidity on a good day. They adjust our equipment to naturally add more humidity during the AC cycles. We do backflips, if we can get 35%-38%. Enjoy watching your channel and have learned quite a bit. I am HVAC school and your input gives me good things to study and learn.
Where in CO are you? I’m in Utah and I would have thought that our homes would need humidifiers, but I’ve yet to live in one that does. Pretty sure our desert climate is same as yours, right?
If you add a attic fan without adding more soffit venting you can end up pulling air from the house instead.
Yeah, it will cool the attic - because it's pulling your air conditioned air from the house
My crazy self turned 24 this year I thought house Ac worked like car Ac. I was turning down the thermostat thinking I was making it cooler inside😅
Also a crappy installer may not have pulled a vacuum....on a brand new system if installed didn't take the time to pull a vacuum...you may only get 15-17 degrees of temp drop across the coil.........also system could be sized wrong from the start
Dont forget when very humid DT may be down to 15F vs 20F.
Certainly affects the wet bulb temp
Those days set the ac to 78 to 80
I have opposite problem its too cold. Can i fix that myself maybe? I'm abroad
Turn down temp doesn’t fix it?
I just put in a new mr cool seems like it doesn't get that cold or even blow that hard
Eek! Hope you get it straight. What made you go with that brand?
attic fans can do harm if they create a flow ONLY AT the top of attic
Price@@NewHVACGuide
my house needed a 4ton system and i called an hvac company and they forced a 5ton on me [ the guy said it was okay to do that] and
saying thats all they had in stock , , so he installed it and overcharged the hell out of me for doing the changeout. . . . .
/ / n no wonder all the hvac guys livve in PLUSH houses. . . . /

I had a new HVAC system installed and the AC unit will keep on running for another 2 hours when the desired temperature is met. Any idea why?
Check the thermostat, some thermostats you can adjust the variance from the set temperature. Reduce the variance value to reduce running time.
I am having the same issue and my thermostat doesn’t allow me to reduce the variance … any other suggestions
@@cyndibridgett2617 is it a Carrier unit? What did the HVAC Tech suggested?
My older thermostat has a ±2 variance. The same brand but digital turns on and shuts down within 2 minutes, trying to keep set temp. I am worried the latter will shorten the life of the AC.
Newer units have a more gentle ramp, but two hours is unusual. At the most it’s usually a 5 minute step down.
My ac in the house stays cool at 74 most of the day. But on a got day it gets up to 78 in house. When sun sets it goes back to normal. Recently I tried to clean the coils and it was great for a week. So any suggestions
Have a pro do a proper tuneup and check air flow and refrigerant levels.
Okay thank you.. good information in this video
@@NewHVACGuide I have a similar problem. AC keeps up early in the day. Late afternoon, house gets up to 78. When the sun sets, it gets cooler in the house. Maybe 75. Hvac guys came twice. Changed filters, checked coolant levels, etc. Told me there is a big ‘box’ in the attic that is part of the duct work and needs insulation. $700+ to get it insulated. That solution was their best educated guess. It sounds like it is not a sure thing. And why now? It is an old system, and they want to put a new one in, but they also say it’s working well. The problem, per the tech is that uninsulated big metal box in the attic. The outside portion (condenser?)is on the West side and unprotected from the Southern Utah sun and high temps.
Is this a problem/solution that seems correct to you? What can we do to help ourselves?
What if repair man tries to break it
I feel like there's a story here...
