A/C Estimate
I have a raised ranch finished above, completely open below. Each floor 1000 s.f. All ducts are in for use with the heating system. The trunk duct line runs next to the center stick beams. All registers are through the floor, nothing in the attic. New house with all updated flex ducts that branch out. Looking to get a split system set up with the condenser outside and tap into the existing inside. How much would that approximately cost? Thinking 5 ton, 7 at the most(overkill?)13 seer. Dont want to spend crazy money on the new hydroair and more efficient systems. House is in new england, AC is used from june to september, july and august alot. I know there is a method to sizing the system, so any help in pricing with install or sizing the unit would be appreciated.

Re: A/C Estimate
What is the r value in the walls, the ceiling, glazing square footage and which direction does it face? What is your latitude? What is the percentage of shade on each side of your home? How much of the basement is above grade? What is the flooring over basement? How many appliances? How many people will be living there? Should I continue?

Re: A/C EstimateQuote:
Before you have any contractors to your home, ask them if they do heat calcs to size equipment. It will save you a lot of time and frustration. Don't be 'impressed' with: "I've been in the business for 30 years....blah blah blah" or use square footage rules of thumb. You can do your own heat calc. Google hvac-calc. Delta |

Re: A/C Estimate
technically yes, each home will have its own heat loss and heat gain "personallity" do to construction factors. but i doubt it's done. with automated CAD programs it wouldn't be too hard to change HTM factors, but again i doubt it's ever done.

Re: A/C Estimate
Use This to determine what size system you need.
And cross your fingers the duct work is big enough. |

Re: A/C Estimate
I got a few estimates in the 3300 range for R22 and the 3800 range for R410A. Is there really a large disparity between the systems. Also, is there a huge profit margin for this type of job, i rough estimate materials at between 2000 and 2300. Should take about an entire day to install. Why so much upcharge? Unfortunately, they are getting the prices so no need to lower down.

Re: A/C Estimate
Because the contractor needs to make a living and pay all of his overhead. Go for the newer R410A system, R22 is going to be phased out like R12 was.

Re: A/C Estimate
air handler, condensing unit, duct work, boots, registers, t-stat line set, plumbing, electric, and labor for 3300 to 3800???? does this guy owe you money? unless this is a side job(which is even super low for that) this sounds way to low to be a good job. cheap equipment and shotty work at best.

Re: A/C Estimate
We require a seemingly huge markup because the business is more cyclical & dependent on good weather just to perform the job. Even very carefully designing & installing or servicing can result in a lot of lost productivity with clients that have a poor conception of what is involved in providing their comfort.
Then there is the fact that I was taught by one of the best that "What we are doing here is precision guesswork" Any in this trade who has been around the block has dealt with something even the factory can't explain. Tract houses that are the same have variables that causes headaches. If you value your reputation, you do whatever it takes & end up eating the cost. Very seldom, if ever do we get reimbursed for the factory's or someone else's mistake. If we don't get such a huge markup, we eventually go broke. |

Re: A/C EstimateQuote:
Not half that, it is an add on to a furnace, plumbing is completed for the condensate pump. There is a plug for the pump in good positioning. All duct work is done, the basement is unfinished for now and all above floor rooms are finished. Just the Condenser and A coil, and obviously freon lines, etc need to be installed. |

Re: A/C Estimate
just take the amount of $2,150 (our cost): Thats about $1,150 profit before expences, and liabilities. If one sold a/c's at the rate of tuna fish cans, than yeah I can see your gripe, but, there is more to it. There are the cost of doing business, not ment to go in detail here.
There you have it, you can save $500 if you go with r-22. What's your pick? |

Re: A/C Estimate
Not trying to offend, i understand how business works. I have done jobs with a large markup as well. Just thought this was 1/3 profit for little work, most of the cost is in the material so in this case it seemed much higher than normal. My choice was R22; will only be in the house 3-4 more years and i know it will become obsolete in the near future but the savings is significant right now.

Re: A/C Estimate
If you know how business works.
Then you know there is no 1/3 profit in that price. |

Re: A/C Estimate
Installing a split system a/c unit takes a lot of skill and equipment, its not like a tv where you just set it down and plug it in. You have to take into account the equipment involved you got gauges, charging scales, refrigerant tanks, torch set up, vacuum pump, vacuum gauge, test meters, brazing rods, and miscellaneous hand tools. The average HVAC tool setup runs about $3,500.00 in just tools that are needed to correctly do an installation and each time an install is done these tools are one step closer to needing to be replaced are serviced, which ads up to a pretty high over head for the a/c company, not to mention the vehicle over head insurance and gas and vehicle maintenance and upkeep and don’t forget the business liability insurance and the license fees and permits all these items cost money on a day to day basis and required on every job . Heck I did not even get to the labor which you have to account in with this Workman’s Comp and unemployment insurance. And this still has not taken into account the cost of doing business with advertising, office space, computers, accountants, phones, heat load calculating software, code books, business cards, printing of invoices and letter head, postage, continuing education, bank fees, credit card fees, bid bonds. Why so hi a mark up? , hell after all this then there is the tax on what is left of the profit on top. Take all this into account then ask yourself at the prices you have above, how much a mark up is there ? There is just a couple hundred buck in net profit after cost at the prices you have. Trust me cheap is expensive, if you want a job for less you can be sure you will get a worthless job done. And a worthless job done, is going to have to be redone right. Costing you twice as much then if you just paid what it was worth to have it done right the first time. Think about it.
