hey,great site new to the site,thought i would ask some questions about my install im trying to do mostly my self to save on cost.My house is approximatly 1500 Sq Ft cedar loghouse and has never had heating or cooling besides a wood stove and window air conditioners. So i thought it was time to install one so i went and bought a 4 ton rheem air handler Model#[rbhc21j18sfc] and bear with me i have a lot of questions to ask this is all new to me.
#1 It has a heat strips installed, but its not really a heat strips, the air handler has i guess what are called factory installed incoloy sheath heaters wrapped around the blower assembly rated at 18.00kw are these enough to heat 1500 sq ft or should i order a bigger heating kit?
#2 Also the electrical it has two 60 amp breaker on the front panel and i have read that it takes 2 #6 copper wires to power it and handle the amps but the wire is not cheap at my local lowes,can i use a jumper kit to combine those two circuits into one to save on wire so i only have to run one wire to the air handler will this be safe?
#3 Also what is a good size supply duct for a 4 ton unit after the plenum? I cant seem to find an answer any where to this question.I have found plenty talking about return size but not supply size for a 4 ton.
#4 Also it is a upflow unit and i have built a return box approx. 2ft X3ftX24 inches tall. well insulated with perma R board doubled up.That it sits upon, going to a 20x20 filter grill which being a log house this is as big as i could go with the limited space and it is hard cutting through a 6 inch thick cedar logs with a chainsaw,to fit the return grill.And my house has limited stud walls almost all the interior walls are 6 inch cedar logs which i do have a crawlspace under the house which is where i will run my supply duct work so is a 20X20 grill and is the return plenum box i built close enough to give it enough air?
#5 Also for a condenser unit outside do i have to get a 4 ton as well? I thought about a heat pump, but right now all i can afford is a regular condenser and later i will upgrade when i get the cash.So i will only have air handler electric heat till i upgrade so will 18.00 kw be enough for 1500 sqft.
Thanks so much, i hope someone cam answer my questions.
