"Nate - I agree with you. If you want to "sell", talk about comfort. People will buy comfort. People are suspicious of energy savings or payback claims. But if you tell the client they are looking at a 50 to 250 year payback, most of them…"
"Hmm. I asked a direct question and got a question in return.
To answer your questions -
Closing ratio is almost 100%. We don't "sell" our services. Our customers come to us when they know they have a problem and need a…"
"David's comment is spot on. I would always prefer thermostat staging control over furnace staging control. (I am assuming the thermostat is making and breaking the control call for heating - not communicating the temperature back to the furnace…"
"Thanks everyone for all the info! This has been VERY helpful.
I have been reading how multi-point tests are LESS accurate than single point tests in high winds. I would not have expected that. Then it occurred to me that the single point test has no…"
"I found this post thru a Google search. I was already a member and have posted a few times.
I am a mechanical engineer who has been doing blower door tests for decades. I only do 10 to 15 BD test per year (I am not doing energy audits or such).I am…"
"Rather than recommend an ERV, how about some thru wall exhaust fan(s) in the bath room(s)? Put them on timers so they don't run all the time.
That kitchen fan REALLY needs to exhaust outside. I would make that a higher priority than the…"
"This looks like a common type of system for Arizona. Most of the time that package unit would be located on the roof and the ducts run down thru the roof. A lot of units installed that way were evap coolers that were replaced with an air…"
"I agree with you so far. But that just means that the vapor barrier is less leaky than the duct. (If the vapor barrier was more leaky than the duct, the vapor barrier wouldn't move.)
But my experience and test data says that…"
"I run into this all the time. You CAN test those ducts. If you want a good quality installation - you should test those ducts and they should meet the leakage specified.. A typical installation leaks 30% of the air thru the…"
"Wrightsoft has an option to include a fireplace in a zone. I would use that option since it complies with the Manual J instructions. If you use some other method (hole or heating source) you should make sure your method complies with…"
"UV lights have their place - but in my opinion are ridiculously oversold. In order to do ANYTHING worthwhile they MUST shine directly on the evaporator coil / drain pan. Any other location and they do nothing useful. Only when the…"
"The fan speed needs to be set to provide the air flow to each room calculated by the Manual J. It was rare to have a contractor do a manual J or adjust the fan speed until recently. The City of Austin (Texas) required thru the energy…"
