BACKGROUND: I am 28 and have been involved with HVAC since I was in my early teens, my dad owned a HVAC company. I learned a lot about residential HVAC and was installing systems by age 16 as a lead in a 20 man company and in sales by age 19. Only in residential forced air. with some a/c.
I went off to college.....then decided it was my best bet to get back into HVAC. well I landed a great job as an estimator at a "oil" company that has a heating division. My problem is that the company is not overly concerned with training me when it comes to boilers and heatpumps. I have sold 1 of each to date.
MY QUESTION(S): I am finding myself seriously half assing my estimates. I tend to include extra money in the bid to cover stuff I don't know about, and I am really worried about the comfort of the people who I do end up selling to. My specific question is this : aside from taking some real classes somewhere, is there a rule of thumb when sizing boilers? I mean anything has to be better than what I am doing which is basically scouring the internet for posts on someone with a similar sized house and hoping for the best when sizing.....
Please go easy on me, I know I am a hack at this point but I want to learn However the company doesnt care to send me to classes as they are a big oil company that really only wants to sell oil and sees equipment as a 'necessary evil'
