AC/Unit how big to go?
I have approximately a 4,000 sqft loft and not sure what size AC/
Furnace Unit I will need. Just trying to get a general idea. I was looking at the following and not sure if it will be able to handle the size of the room. Goodman Air Conditioner/Furnace Package Unit GOODMAN Model: GPG13360901AB 13 SEER (cooling) Cooling capacity: 35,400 BTU 80% AFUE (heating) 208 / 230 Volts 60 Hz 1 Phase |

The vague definition is "sorta kinda good enough, but look at other brands". As far as the size, a competent contractor will survey the space and make a recommendation based on more factors than just square footage. Another factor would be the number and sizes of windows, for instance. You should consult a contractor. |

Up here, rule of thumb for cooling need is 1 ton(12,000BTU) per 600 sqf. I am no expert but looks like you need bigger one. |

AC/Unit how big to go?
Thanks for all the replies. I did have one guy come by and his
estimate was nuts, so I was trying to get a rough idea before I called more. I think I will need bigger than the one I listed almost double from what I have calculated.

The 'experts' measured the house and checked the insulation and then told him that the manual whatever showed that he required a 2 ton (24,000 btu) system. He ended up with a free 5 ton (60,000 btu) system that has kept him very happy. The 'expert' hvac guy was not very happy, though. . - Hide quoted text - - Show quoted text - |

Have a HVAC contractor in your area come by your place and perform a heat load.
You really need to find the right size because if it's too small it will not cool properly and if it's too big it again will not cool properly. Question is this a window unit? If it is you can go to a number of places to find the right size for window units and you will not have to have a heat load. They are generally for central air. -- Moe Jones HVAC Service Technician Energy Equalizers Inc. Houston, Texas www.EnergyEqualizers.com "Deejay" wrote in message ups.com...

unit. On Jul 5, 11:08 am, "Moe Jones" wrote: Have a HVAC contractor in your area come by your place and perform a heat load.

AC/Unit how big to go?
The 'experts' measured the house and checked the insulation and then told him that the manual whatever showed that he required a 2 ton (24,000 btu) system. He ended up with a free 5 ton (60,000 btu) system that has kept him very happy. The 'expert' hvac guy was not very happy, though. That's great if you like that "cave clammy" feeling. It will be a cold house that still has all the humidity since the oversized unit won't run long enough to pull the humidity out. That may work fine in Arizona but here in Florida it will make it "rain" in your house as the humidity condenses on things.. I would have used a 3 ton if the "experts" said to use a 2 ton. Having lived in Las Vegas for 15 years, I learned early on that too many "experts" and contractors use the one ton per ~400 sq ft rule, and you end up with an a/c unit too small to cool your house when the temp tops 115 (which is does for weeks on end in July and August in Vegas). I replaced my 3 ton unit with a 4 ton unit, and I was in a/c heaven! However, Vegas is quite dry and quite hot, so we don't need much dehumidifying action - we need extra cooling. My office needs a 5000 btu a/c according to btu/sq foot charts. A 5000 btu a/c runs and runs and runs during the peak of the day, it doesn't cool that well. I now have a 6000 btu unit in the window sill The extra 20% is all it takes to make the difference between sitting here sweating during the heat of the day, and enjoying a nice cool office. Anyone else care to comment on whether you go with the recommend size, or upsize 20% or so? IANAE, and my limited experiences are certainly not representative of a/c installs in general. |

Mine is 22 years old this month. It's a trane and it keeps on running, but I supplement it with wall units that are very high EER so I hardly ever fire it up. But, I am not getting anything but a multi-speed compressor unit. "Right sized 2-speed high SEER (15+) heat pump HVAC system with variable speed blower. A 'right sized' system with a multi speed compressor assures that the unit has a sufficient cycle time to both provide desired comfort level and optimum dehumidification." Pay more now and enjoy 10-20 years of comfort. |

AC/Unit how big to go?
Why? A competent estimator performing a manual J calculation will give the
proper size to use. Because I've spent too many years living in houses with a/c units that were sized according to the house size, and most of them ineadequate. When it hit 110+ outside, we sweltered inside because the a/c just couldn't handle the load. I've had several of my units inspected by repairmen, and all of them told me that the unit was working fine but just wasn't big enough for the house. I had a 1200 sq ft house in Vegas, and a 3 ton a/c. It didn't cool worth squat when the temp exceeded about 105. A contractor told me to replace it with a 3 ton unit. I told him that the current 3 ton unit was fine mechanically, but would not cool when it got too hot, and then he suggested that because it's hotter in Vegas I might need a bigger unit. Well, duh, why don't they do that in the first place? There is a big difference between the size of the a/c unit need to cool a house in 90 degree humid weather, and 118 degree arid weather. I wonder if the problem is that the contractors use the smallest unit they can get away with, instead of one that will cool the house even when the weather hits 118? IOW, a competent estimator would indeed give the right size to use, but those that build houses like to cut costs when they can, including using small a/c units? Unfortunately a BTU/square foot chart is only an extremely course guide and isn't really accurate enough to properly select equipment. Agreed. A couple of computers, other electrical equipment, a souther exposure, etc. can make big differences in the size of the a/c you need. |

Builders use as cheap as they can get away with. The manual J is a very good method of determining the size AC you need, but, it is dependent on proper input. If you design for a 20 degree differential, but want a 30 degree differential, it is not going to work. What works for me so far, is not to live in a place where the temperature reaches 118 degrees. |

Well, duh, why don't they do that in the first place? You just answered your own question. The calculations can't be correct when the correct design conditions aren't used. You get similar results in an area where heating is the predominant issue. If the builder is trying to cheap out they use a higher outside low temperature with the result being if there is a sustained cold snap the inside design temperature cannot be reached. There is a big difference between the size of the a/c unit need to cool a house in 90 degree humid weather, and 118 degree arid weather. Sure, and manual J accounts for that. But if the right conditions aren't used then the calculations are useless.

Supposed to be 116 here today. Wonder if it will make it. Steve Ahhh, Las Vegas, home sweet home. 116 this early in July? Niiicceee. I have fond memories of painting the eaves of my house in early August when it was 118 outside. I had no choice, as the house was selling and I had to get it done. I thought I was going to die up on that roof.... |

I'm waiting as I type for a company to come install a compressor in one of my vacation rentals. Seems like the morons renting it have been having problems for a couple of weeks, "but the temperature was bearable." The house has a five and a four ton unit. I can't say 100% sure that it wouldn't have gone out anyway, so I can't charge them. Grrrrrrrrrrr. And how old is the unit??? Anyway, I always heard that ......... go with a bigger unit, and then it doesn't have to work as hard. I know that this, too, has its logical limitations, as you would not want to put a ten ton unit where you need three. But I do consider putting an extra ton on there to be a reasonable thing to do. Is the ducting adequite for the extra ton??? We're replacing this compressor with another five, as the house has nine tons for 2800 sf. And yes, the units don't run that much of the time and it doesn't take long to cool it down. Plus, for a few months a year, two swamp coolers blow plenty of cool air. Why did the compressor go??? I'd sure want to know why before I spent money on the replacement. Is your ducting adequite for the 5-ton unit??? |

kjpro @ usenet.com wrote And how old is the unit??? 18 years Is the ducting adequite for the extra ton??? No going to increase the tonnage, just replace what's there. I was merely stating that when initially putting in a unit, I would opt for slightly oversized rather than marginal. Please reread following sentence. We're replacing this compressor with another five, Why did the compressor go??? The fan motor seized, and the renters just kept turning the thermostat down instead of alerting me of a problem. Thus, the compressor ran 24/7 for two weeks. I'd sure want to know why before I spent money on the replacement. Sometimes, **** just happens. Tekkie said it was 95% old age and 5% renter stupidity. Is your ducting adequite for the 5-ton unit??? Has been since the unit was originally installed. Steve |

wrote If you don't need the whole house cool all the time 2 systems may be your answer. Knock the bedrooms down at night and hit the "living" part of the house harder during the day It's the ONLY answer if the house is over 2200 sf. Steve |

"Right sized 2-speed high SEER (15+) heat pump HVAC system with variable speed blower. I knew they had variable speed blowers, but how is it possible to have a 2-speed compressor? A 'right sized' system with a multi speed compressor assures that the unit has a sufficient cycle time to both provide desired comfort level and optimum dehumidification." Pay more now and enjoy 10-20 years of comfort. Some say they have dual compressors and others say they have dual speeds for a single compressor. They are quite popular but expensive so more new ones are coming out all the time. |

"Ook" Ook Don't send me any freakin' spam at zootal dot com delete the Don't send me any freakin' spam wrote in message ... Ahhh, Las Vegas, home sweet home. 116 this early in July? Niiicceee. I have fond memories of painting the eaves of my house in early August when it was 118 outside. I had no choice, as the house was selling and I had to get it done. I thought I was going to die up on that roof.... On the good side, the paint dries so fast when you're painting the eaves, if you drip some, it just bounces off the concrete. We're 98% moved to Utah, and are just waiting for the houses here to sell. I also have lots of fond memories of Las Vegas. Lately, it's just turned into a crowded cesspool. I liked it better when "The Boys" ran things. Steve I moved there in 1984, and left at the end of the year 2000. When I moved there, there was no Green Valley, and US95 dead ended at the spaghetti bowl. Lake Mead Drive (not to be confused with Lake Mead Blvd in NLV) went from the old part of Henderson all the way to I-15 with only one traffic light, and there was a couple of miles of empty desert along Boulder Highway between Vegas and Henderson. There was also an empty mile or two of Las Vegas Blvd at Nellis AFB. You could actually drive across the dam, and the tours took you down the looong elevator to the bottom platform. When I left, the road to Lake Mead had a toll station, the city was complete from Vegas all they way along Boulder Highway to Henderson, and Green Valley stretched from I-15 to Water Street, civilization stretched all the way to the air base and beyond, traffic was insane, and it was beginning to get very crowded. Real Estate had not yet exploded upwards, and I sold my house for $99,500. Today that house is worth about $250,000. I walked away $150,000 - all I had to do was stay there for five more years cries. I moved here in 1952 at age 4. Henderson (where we lived) had about 7,000 and Las Vegas about 40,000. Now they're pushing two million. Over the years, I did well on some deals, careers, real estate and various gambles. Did really well in silver before the Hunt brothers messed it up. Boy, did I sell at the right time! I've seen a lot and participated in history. I worked at the joints. I sat and played blackjack with Elvis for 45 minutes one time. I played ping pong with Pearl Bailey. Shecky Greene tried to choke me. I met lots of celebrities and had elbow to elbow contact. Lots were nice folks, and some were absolute jerks. It was a good ride. But now, it's over, and I'm ready for a rural existence in Utah on my ranch and at my cabin. Lots of fishing and hunting and ATV riding to be done. Anyone want to buy two vacation rentals in Las Vegas? $950k. Steve |

Now all they see is an old POS that someone spent a LOT of money on for a repair. To them, it's still something that they're going to have to replace. It's a mind game and the game says you're likely to get your money back on a new system first. It makes the home more appealing and that means more money. That's why!!! :-) |

Perhaps-useful mental model: Consider an a/c that's so much too small that more heat keeps coming in through the walls, windows, leaks, etc, than the a/c takes out. Result: room keeps getting hotter, until at some higher temperature equilibrium is reached, and it shuts off. David |

David If you are using a room AC or a mini-ductless AC by using 20" vertically adjustable fans (Wind Machine 3300) you can cool a lot larger area. I cool 3 rooms & a hallway in an older 1937 home that is over 850-sq.ft with a Half-Ton mere 6,000-BTUH room AC in 104 Heat indexes. http://www.udarrell.com/aircondition...harting.h tml Somebody is really nuts to be using 9-Tons to cool a mere 2800-sq.ft home. What would an accurate Manual J heat-gain calc call for, 2.5 to 3.5-Ton? Without sufficient runtime, - as the sensible temperature drops the percent of Relative Humidity rises causing a clammy mold spore producing environment! It appears he is using at least one 5-Ton & perhaps a 4-Ton. Both require a lot of airflow to work properly, the 5-Ton airflow level is not easy to achieve in a residential system. http://www.udarrell.com/proper_cfm_b...syste ms.html udarrell -- WISDOM PRINCIPLE DIRECTED EMPOWERMENT COMMUNICATIONS - THE REAL POLITICAL ISSUES and WISDOM BASED PEOPLE EMPOWERMENT http://www.udarrell.com/ http://www.udarrell.com/my_pages2.htm (My Airconditioning Links, Hunting Shooting, Angus Cattle, etc.) http://www.udarrell.com/principled_a...ju stice.html http://www.udarrell.com/recognizing_real_enemies.html http://jesuschristsavior.net/Beatitudes.html http://www.antiwar.com/ *** Reality Is Not An Easy Thing To Be Confronted With, or to Accept! |
