Don't you guys love it when the professionals comment on these videos and point out the flaws so that they can feel good about themselves? Sure there may be flaws, but overall, its a pretty good video.
Good info and thanks for posting this vid! Only thing missing was better ways for DIY cleaning the coils instead of "calling a pro" to flush it out from the inside. This isn't something you need a pro for .... Show us, then let us determine whether or not we can do it ourselves.
In summer season air conditioner plays very important role. Very well demonstrated video showing complete procedure how to clean and service of air conditioner.
Very useful, thank you! Gonna check all this out tomorrow, supposed to be 100F (Yes, I waited until it's too late to check my a/c health, hehe). My central air unit is in the attic and looks similar but lays on it's side.
Hi David, thanks for the video. Question: My HVAC stopped working this week and I got a company coming on Monday to install a new unit. This old AC that just broke was here when I bought my house brand new 14 years ago, so yes the AC was 14 years old. With that said, do you think, I need to replace the ductwork as well? Also add return vents per room? Coz right now I only have one 30 x 30 return vent by my foyer. None in the rest of the house. Your advice is appreciated. Thanks!
Great video Question : I have a 1.5ton 220volts split unit AC. After few seconds of turning it on the clamp meter reads 22A then rise to reach 37A for few seconds then it stops and the clamp meter reads zero or 0.1A. What could be the problem ?
I would urge people not to spray their condenser coils with some unknown "cleaner". These days coils are either all aluminum or aluminum fins on (too) thin copper tubes. Chemicals in some cleaners can severely damage these metals. Most of the time water is all that is really needed.
@6:20 - Those cheap filters are great for keeping out sticks and stones, but not much else (even if you DO check the wrong side). A 4" filter is the way to go.
As an hvac technician myself i just wanted to point out that what he said about that suction line needing to be insulated is correct but the refrigerant inside that line is actually coming out from the house its coming back to the compressor so in reality your not really losing any cooling efficiency, great vid though!
This one provide the viewer some good tips and ideas. If unsure on what to do or need maintenance for your air conditioner always rely on the experts to avoid bigger problems.
My unit is a roof top unit never had the coil cleaned in 10 years it draws the same current that it did the first day they installed it I keep records. Once A year I put a current clamp on the wire going to my unit and measure it that's all I do. You don't need to clean the coil unless it's on the ground and has a lot of junk in it. Keep plants and trees away from the unit and it won't get dirty.
Have you heard about using Cold Plus refrigerant additive to get colder air and use less electricity? I heard that both commercial and residential units are saving between 8% to 18% utility bill savings...is that possible?
So my AC isnt blowing super cold air its not warm but its not cold like normal when outside the unit is running and the fan is running so any idea why I'm not getting cold air
Good information. Now I know what to do with the outside unit in terms of cleaning it. Please talk louder, especially when you are not facing the camera. Thanks
I use a garden hose to clean out the fins, goes from black to silver pretty quick, so I know it's working. Anyone see a problem with cleaning using a garden hose, high pressure?
Using a garden hose is a much quicker and is way more efficiant at getting the dust & debris out of the coils. The insulation on the 3/4 copper line is more for protection. It's cold, but it's going to the compressor, not the furnace coil. 1/4" of dust on the blower wheel could reduce airflow by 20%. Take the temp between the supply and return, it should be between 15-20 degree differance.
most ppl try to do their own maintenance and cause more damage then they think if you're not a certified tech I suggest you call one. save yourself and your unit from harm and putting a big whole in your pocket.
great video.....many folk are now upgrading their homes to..... 'mini split' units just a 'heads up'.......they are modulating with and are reverse cycle... for winter heating...
A great place online to get supplies to do your own air conditioner maintenance is HVAC Maintenance & Supplies google it and check out the air conditioner maintenance kit or coil cleaner links.
The low side may pick up excess superheat (SENSIBLE heat, not LATENT heat), especially in hot weather, which in turn will cause the compressor to run hotter, possibly causing a mechanical breakdown and reduced lifetime. Yes this narrator was wrong about the function of the larger diameter tube, but it still needs to be insulated!!
I have a 10 year old Lennox Central AC Unit. The fan stopped moving, so I had the motor fan and the Capacitor replaced. Then it started working again. After 30 minutes, the fan would stop moving while the compressor was running. I could feel the heat generating from the compressor. Turned off the circuit breaker. Tightened the wiring, then the fan worked again. 30 minutes later, the fan shuts off again. Can someone tell me what the issue might be please?
might be mixed up overload relay switch is it connected right to compressor or maybe its to the fan motor since it turns off when it heats up , or call a tech
Eddie Barrios do you have a heat pump system cause that one thing it will do fan shutdown then the reversing valve goes into cooling then auxiliary heat come on you might want to see if your defrost board working properly
5:58 I thought the first audible click was to represent powering off. Then again....again....again and then it occured to me it's part of the music audio.
Dude the insulation is not keeping the refrigerant cold going back in to the home, it's already cold coming from the evaporator in the house and absorbs the superheat becoming 100% vapor, the insulation is to insure that the refrigerant doesn't condense into a liquid and cause catastrophic damage to your compressor, it is a vapor pump not a liquid pump, the insulation holds the heat in until it reach the compressor then the condenser blows all the BTU's out!
Why is the title listed as Air Conditioner Maintenance when the video flashes "Conservation Tips with David Mars" - that's two different things. Need to change the title.
really this is my 13th year professionally never seen a paint brush used to clean a coil...just spray it with condenser foaming cleaner and rinse with a hose...saves time and actually foams out the dirt not packing it in with a brush..this is a joke then he shows how check the back side of the air filter like that side really gets dirty?
RUST?! Those are copper lines my friend, they will never rust I assure you. DO NOT under any circumstances mess with the copper line set. Also, the coils have copper end loops but mostly use aluminium where the lines pass through the fins. The biggest problem is dissimilar metal corrosion in the presence of moisture on the evaporator coil, and the most likely source of leaks after about 5-8 years. Coils should be replaced when leaks are discovered.
The comment left by tmaretzki: What is pop up north and soda in the midwest is coke down south. Doesn't matter if it's root beer, Pepsi or Sprite...it's all "coke" around here. Same with oxidation...doesn't matter if it's copper, brass or metal containing iron. Right or wrong, in the south, oxidation is called "rust". Stage 1 of copper oxidation does produce a rust colored residue but as we all know (or as we say in the south, y'all), eventually turns green the longer it's exposed to humidity.
Cleaning a coil your way could take half the day, call an air conditioning company and just get a full service check. Better advice and not that expensive.Life is too short to brush out condenser coils and you won't end up with a mess you may create!
Any service guy shows up making those faces and they'll be exiting with one hand grabbing the back of collar and other giving you a wedgy as they're escorted OUT!
For those of us that can’t hear very well your background music gets in the way of hearing what is being said! Why obstruct your voice? It’s like throwing a bale of pine needles at your condenser and clogging up the fins. Now, can you relate to that?
When a pipe is hanging out the outside of the wall on the outside what do I do about it. And is broke and I can't fix it please help me I'm trying to see if it's supposed to be some foam or what cause it leaks on inside floor and wall.
WHAT!!! That unit (the outside one) DOES NOT deliver the cooled air into the home!!! BUSTED!!! within the first 2 minutes of the video! 1 minute to be exact! The evaporator inside the furnace unit inside the home provides the cooling surface that the air travels over and moves the cooled air into the rooms of the house or whatever you are trying to cool. This unit (at the beginning of the video) sits outside because it takes the heated gases and cools them and condensing them back into liquid form before returning to the evaporator 'cooler' (changing the liquid into gas) and back again. You showed the wrong side of the filter!!! The other side collects the debris from inside the house!!! The clean side must always be on the blower side. This guy does not know what he is talking about!!! He IS telling you to damage your unit by cutting the drain pipe. You need to open that panel and inspect!! You should inspect once a year and clean if necessary. If the filter is changed regularly then the unit does not need to be cleaned very often....like....every five years. The drain pan in the evaporator unit must stay clean and the drain pipe or hose to the outside drain or floor drain if that is how your system is configured must drain the condensation away from the unit. High humidity areas are more difficult to keep clean mostly because of the mold from inside your home. Way too much BAD advice in this video!!! FREE ADVICE from a Master Technician - I hope it helps
