No one needs to do a load calc.

We should start a buisness with all propper QC

We'll start with your spelling, I know mine sucks two.

I don't see why they would do it before providing an estimate.

Shouldn't they do one, so that they can provide an estimate.

It is not that difficult to learn how to do fairly accurate load calcs.

Even I can do them, & have only a few brain cells left.

You have to evaluate the duct system, airflow, etc., before you even consider providing them with an estimate.

A load calc is essential before providing any equipment sizing numbers.

If the heat gain & loss are considerably more than what is considered, in the ballpark, then weatherization work is called for along with duct efficiency work...before proper equipment sizing takes place...

That is all I am asking for. To get someone in and look at this place. and get an estimate and equipment suggestions.

I have done one using HVAC Calc Residential 4.0.

The house is 1200sq ft for basement and 1200sqft main floor R20 in walls on main floor, R38 in half wall in basement R10 foamboard for 3 ft of concrete basement walls. 1600 sq ft vaulted ceiling with R38. The main wall is 435 sq ft south east facing and has 181 sq ft of low e argon windows so both heat gain and heat loss.

I come up with a 2 ton for cooling

They are the only company willing to do a site visit and a load calculation before supplying an estimate.

a.k.a. You do it MY Way, or hit the highway ...


Any1 should give you
1. estimate
2. load calc
3. visit

... so here it is
1. A lot ... $ 1#,3#5.#7
2. Same as you stated above.
3. WHERE Are you buying me dinner?

[JimmyP]

I don't understand all your jibberish dan sw fl.
1. they need to visit to evualate.
2 see and understand what is required
3 estimate and properly size equipment

[JimmyP]

I should have put it out there as a question for all of the ones that don't understand. Why does everyone think that they don't need to do a load calc.

[JimmyP]

Try Mat at Aire Serv.

I would think he would be able to handle this request.

He hasn't replied to a request.

[mechanical'al]

just guess how much of your money you'd like to give them and flush the rest as a rot

[JimmyP]

Jibberish?

No Dinner

Your Falcon link is so true they are amazing. I was 200 miles offshore in the north atlantic and one landed on the rig in a storm. . It was injured and we sent it to a nature park to recoup.

That company showed up and did some measurements and came up with 38000 BTU's/ hr heat loss. So a 3 or 3.5 ton system needed.

My electrical utility bill average for Dec to Feb was 1500kw /month this is 170500 btu's day and 12 hours / day ( darkness without solar gain) of usage would be 14208 btu's/hr. There is no way I would need 38000btu's hr.

we don't base a load on average.
you may keep your thermostat at a different temperature than the manual J suggested temp.
