for the mitsubishi units it's a stranded 14 gauge 3 wire (plus ground so 4 wires total). 2 of the wires carry power from the outside to the inside, and then with the way mitsubishi is designed 2...

I'm sorry, i didn't specify. I'm not going to speak for samsung directly as we do not deal with them, but with the Mitsubishi brand units the power goes from the panel to the outside unit directly,...
your saying that you are reusing the electrical and freon lines. Are you positive that the electrical is correct. We had a customer with a mini-split that said the original installer had board...
i actually have one on my condenser. Yes it's mounted on the suction line just prior to entering the compressor. My unit is 4 yo and i haven't really noticed any fin corrosion as of yet. Granted it...
the appion is a great machine. as for the refrigeration cooler. we've never needed it. We always put our reclaim drums themselves into a bucket of ice water. does the same thing as the refrigeration...
I had a package that was shipped to a friend. I checked the tracking on it and it left the ups facility in ks only to return back there two hrs later with a note on it about the weather. It still...
as both moto suggested you need to add the heat to the interior of the home not the exterior coil. Or as shophound suggested you need to reduce the heat loss in the home, by adding insulation or...
We have the 10 gallon bucket that you get chlorine tabs in from the pool supply. We put ice from our ice machine in the bottom place our reclaim drum on top and then fill the rest with ice. after...
that's common practice for apartment complex and other hacks. Instead of putting an extra reducing fitting in there they just pinched it closed. Nothing to worry about as far as safety/health.
During Ike in 08 95% of our island was covered in water ranging from 6" to 12' (I had 7' myself). If the water made it up to ANY electrical components...including the terminals on the compressor...
as Jtrammel stated your R/A is too small and not letting enough air flow over the heat strip and causing the limit to trip one set of elements off. That's why when your tech came out and checked the...
if your using standard 1/4" hoses and manifold then anything over a 5cfm pump is completely useless as the hoses won't handle anything more
yes it's the static pressures on the system. We had a customer who had an infinity installed and placed the returns and ductwork to their specifications and we told them the only way the system...
Depends on the number of ducts coming off of it, as well as available room. The more ducts the longer the plenum. Ours are a min 4' long, I know the pre-fabricated ones the supply houses carry are...
After hurricane Ike hit in '08 we had so many out of state contractors come in and put do installs. We went behind at least 6 that I know of for sure that we had to tell the customer the only way...
in '08 Hurricane Ike came through and I lost my A/C. When I replaced my system the local parts house manager (whom i'm good friends with) gave me the nordyne iq drive at her cost. it dropped my...
If it was me neither would be big enough. A 20x20 grill is only large enough for a 2 ton unit, and the 14 in duct if it is galvanized would only handle ~700 CFM so that's less then 2 ton at...
here a duct blaster test is required to pass inspection. it is done by a 3rd party to avoid conflict of interest.
Is the return hooked up properly, is it large enough? Is this something new, or has it been an ongoing problem?
interesting to know dan. Wish they would do something like that here. Granted we tend to shy away from new construction, except for rare occasions
The reason it's stuffy at night when the door is closed is more then likely more a lack of return air rather then anything to do with supply air. Basicly what happens is with the door closed the air...
only need to be changed when they are going bad. For the contactor if its showing signs of pitting or if critters have gotten into them. Or down here the coils will start to corrode. As for the...
actually it's bad to put the drier up at the evaporator in a hot attic environment. One purpose of the DRIER is to dry the refrigerant (capture any moisture not pulled out during a vacuum). If that...
The drier is internal and the refrigerant will need to be recovered and then can be reused.
an 18X24 grill is a bit small for a 2.5T unit. A 14" Flex is only good for ~500CFM. Depending on how it was designed a 2.5T unit is between 875 CFMs (at 350cfm/ton which is what we use here due to...
couple of factors there. The equation that we use that filter grill would be bare minimum size for a 3t system. As in I wouldn't put anything in front of it or use any sort of restricted filter...
We have done the mitsubishi's in media rooms before. Usually a two head system, (two indoor sections) whisper quiet. Can't hear it when movies are playing and the rooms stay as comfortable as...
if it's jsut one room have you looked at the ductless systems
Rheems hold up well when you get away from the actual beach. Down here rheems are used as the builder grade units and they do NOT hold up down here very well. If someone gets 10 years out of a...
I got the fieldpiece srh2 for x-mas, but when we started doing our spring checks I didn't like not being able to take pre-post evaporator temps with wb. So i contacted travis and talked about their...
They won't be cleaning it in place. It's best to pull the coil and clean it. And that can be done pretty much no matter the temperature. If it's too cold granted I wouldn't want to do it, cause I...
The O.D. of the duct means nothing. It's the I.D that gives the size. But even if they were a 16" I.D there isn't enough R/A for a 5 ton system. The R/A grills you have are good for ~4 Tons so...
supply air wet bulb, return air wet bulb.
most of that stuff is gonna change depending on the environment....ie superheat will relate to your IndoorWetBulb and OutDoorDryAir. Your Delta T will depend on humidity. The Subcooling will...
It's not they move more air, but ~80%+ of homes do NOT have the correct size ductwork. If it's not properly sized from the start just because you have a higher eff. heater/AC will not mean much.
...
The major things for the installation is the fact that more then likely the ductwork isn't sufficiently sized for what you have...ie big enough R/A and enough supply. Going with a higher efficient...
equipment life depends on location, maintenance, and proper installation.
Around here average life of a condenser is ~8-10yrs. Furnace ~15 depending if it's attic install or closet unit.
i hate those green and the blue filters. put it this way if you can see through it dirt can get through. Next stop is the cooling coil.
I agree with JP on this one..only time i even take out my analogs now adays is if i have a known burn-out that I need to reclaim.
down here it's local code that a solid piece has to come out of the cabinet, as well as no gas piping going through the R/A chase.
The R/A is NOT big enough for a 5 ton as it is ATM. Have a current load calculation done before just upgrading your tonnage. Also how can they say your ductwork is fine for a 5 ton if it was...
First off I want to say "Thank You for your service."
Now there could be a couple of reason's they are suggesting to replace the furnace along with the ac, and without seeing the equipment or...
I agree with mark. We took a class this winter and the instructor informed us that one reason that 22 uses mineral oil, is that when it was first being produced the mineral oil was cheaper then the...
based on your original post that would NOT be the first guy i'd call back. if the big line (the suction line) wasn't even cold in last years heat wave and he said it'd be ok and a 15 degree split...
Both Bald and Skipped are correct. If your ducts are flex he's being overly generous on the numbers. The other thing is the actual R/A grill opening size. With the system only being 3 years old...
home warranties are worthless when it comes to the A/C unit.
did you email russell or travis? Both can be found here on the forum. I know russell was out of the office last week.
I know appion has their VCRT and 3/8 hose in a combo pack. I just bought 2 of them. Don't remember the MN off the top of my head, but it's on their website.
looks like my garage prior to Ike in '08
Go with the company that does a Manual J on the house first and foremost, along with a duct inspection (Manual S and D) That's the company I'd go with.
