I have a manufactured home with a coleman-Evcon furnace Model #DGRT070AUA. The furnace is equipped with a 1/6hp blower motor that shows 1000rpm. I'm wanting to increase the cfm's and noticed on the furnace data sheet that a 1/2hp motor was an option for the furnace (part# 7900-6051). I called around to several places in town and one individual told me that the furnace I have does not offer a bigger blower motor housing/assembly but they do carry the 1/2hp motor. They sent a tech out and he wanted to know if I wanted to have it installed saying it would increase the CFM's. Well I talked to another company and they are saying it will not make a difference on the hp or rpms for that matter, basically the hp rating is for bigger blower wheels. I've tried to call evcon-coleman several times but no luck. Now in speaking with the original tech and voicing my concerns he basically says the other company is wrong and laughed that I would believe someone else over him (I also mentioned that I asked this question on another internet based HVAC site (not this one) and they said it would not make a difference either) and really laughed that I would take the word of someone on the net). I'm really confused. He said that the 1/2 hp motor has an rpm of around 1200 but when I asked him again today when he called he said to beleive whatever I want. Kind of pisses me off that this guy is being an a-hole. Bottom line - will a bigger hp blower motor with same size wheel and assembly increase cfm? Thanks for the help. -Shawn One more thing - why would the manufacturer have different hp blower motors listed on the data sheet, with my 1/6hp motor being checked, if you can't get a bigger assembly and the hp doesn't make a difference on cfm???

I asked in a previous post about my leaky drip pan that is placed under my air handler. I got some good replies, which led to why is my air handler leaking in the first place. Good question. I know the drip pan is a back up but I cannot remember if there had been water in it before. I attributed the extra water in the drip pan to the very humid weather we have been experiencing. Shows what I know. I did check if the pvc line coming out of the air handler was clear and it is. I also checked the drip pan pvc line and it is clear as well. So what might cause this - so much water to fall in the drip pan? Any ideas? Too, we will remove the drip pan, since in a previous post I said the drip pan was leaky and will be replacing it. How do I lift that air handler? It has doubly stacked two by fours placed under three areas beneath it. Should I joist it, jack it up or get two men to help? How heavy do these air handlers tend to be? Thanks again.
