new hvac quote w/ load calc, but questions
Comments (3)hi tigerdunes and thank you for the reply. i live in virginia (real close to D.C., so it can get hot and humid but also cool). i have a heat pump. electricity is expensive but its the only option unfortunately. the 3.5 ton seems fine now. it cycles on and off, but to be honest, i dont really know how it handles extreme heat. i think if it wasnt doing the trick, i would know. i like it cool in the house, and keep the thermostat at 72 degrees most of the time in the summer and 70 degrees most of the time in the winter. if the 43000 in the numbers you provided were cooling and heating btu's, then it doesnt look like im too far away from the load calc results. i think it was pretty accurate as i watched him do it on a sheet of paper. i dont foresee any improvements down the road really. if the 4tee3f49 air handler wasn't so tall, i would probably go right ahead with it, but the 4tee3f40 is shorter (as ive been informed) and would fit better. im not sure how short the return air box can be w/o causing a problem. if it can be around 13 or 14" then i think i could go with the 4tee3f49 air handler. so i guess the main issue now is, go w/ a shorter return air box underneath the air handler or undersize slightly. thanks again for the reply. i thought for a bit i may have been oversized since it was cycling more than i thought it needed to at times. humidity control is not bad either....See MoreGoing to start looking for a new HVAC system.

Comments (14)I have a half-ton window unit that with large floor type fan cools 1200-sf per/ton in 100ðF weather. On July 18, 2011, as reported on WI Public Radio; very near me, Prairie du Chien, WI had a Heat Index of 127ðF, yes, 127ðF Heat Index! All shades pulled, etc., my little Half-Ton first floor A/C cooled all rooms to 76ðF or 77ðF & and rarely above 55% relative humidity; with good air movement, -- totally comfortable all day. The same for the up-stair's less than Half-Ton window A/C, cools my bedroom, hallway & bathroom; I use a Wind Machine 3300 to move the air throughout the rooms, both on first & 2nd floors. If everything is design-engineered perfectly it is possible that a 3-Ton A/C could cool a 3600-sf home.

Comments (1)I'd be more than happy to help you but your model number is incorrect. I think you mean a B1HH048 and your missing a number from the serial number. I think the unit was made in middle of January 1998... from what i can tell....See MoreNew HVAC for major remodel in California pricing & system questions
