Maybe you should experiment and see what gives you better results, maybe its not the Air Advice. We have seen huge results in 2nd test.

One thing I would like to say. If you found these big holes you could put your finger through, why couldn't they? If you could build a air dam for the toe kick outlets under the cabnits, why couldn't...

Let your heat pump run with heat strips. Electricity is not 200% to 300% efficient, electric resistence heat is 1 watt of heat to 1 watt of electricity, a heat pump is 3 or more watts of heat to 1...

Don't understand this! I've never had a unhappy customer where we have installed zone system!

Yes there should be a drain to deal with the water! I highly recommend you have it checked by qualified tech, if they didn't follow instructions for the flu pipe there might be other issues that need...

Beware of vent free fireplace, you stated you sealed better than most. Where will your combustion air come from? Where will the carbon monoxide go? Think about it!

Really enjoying reading all this, its amazing how we can sell all this high tech stuff and not know how to hook it up. Maybe we should read installation instructions, if that doesn't do it call the...

Also IMO its not worth spending alot for a back up furnace if your heat pump is your primary source.

You guys sound like brand groupies! 3 stage? some manufactures have modulating furnaces. Don,t limit your search to those products!

Sorry to say this is not uncommon in new construction. Your best bet is to find a company that can do air diagnostics and really evaluate your system. A couple of questions to ask when looking for a...

Hey Irish, This is my only problem with Lennox, It may be a great furnace but if customers don't have access to a good Lennox dealer their SOL! Thats what happened in our area. Whats the point of...

I hate duct board! Before you even think about it look inside it, all you will see is fiberglass. It holds dirt better than any other duct out there plus gives you a constant supply of fiberglass to...

I think its a great idea, besides getting rid of the hole, a sealed combustion water heater is safer than conventional. Most people don't realize that furnace/water heater closets are outside the...

They should be looking at the fault codes, the blinking light should tell you something. Most furnaces have a fault code sticker one them to tell you where the problem is, others you have to find in...

They still require load calculations (room by room) to deliver proper airflow for house to be balanced, we can't even get our own industry to do that, what makes you think plumbers will? There is no...

Only if you want to replace your whole duct system! I don't know why they are leading you in this direction. High velocity duct systems have there place but both conventional and high velocity will...

Coleman is the same in that model, York sells builders models also. Don't look for a unit to solve your comfort problems, the duct system is what you should be looking at.

I agree with the other concern of the proposed tonage to cool the home, thats 500 sq. ft. per ton, the old rule of thumb from 25 + years ago, in this day and age with the construction the way it is...

We have found that dampers are very reliable, very few failures, be glade you have a zone system

lol

Is the Nordyne your talking about using the inverter technology that the mini-splits are using? If so I think its about time! Think of the zoning we could with that kind of control between compressor...

One thing about waterfurnace is the requirement for basic training, should be required by all, not sure if it is by others. My first closed loop geo job I started with other brand, information was...

The easiest way is to find a contractor that perform manual J load calculation (room by room) and a manual D duct design. Unfortunately that may not be that easy either. If I was a consumer I would...

I installed a munchkin in my own home, and yes the only difference is one is wall mount and the other is floor mount. As for why 1 vent is 3" and 1 is 2", I don't know, I used the vision 1 and I...

Thanks for your support! And a message to "truck" if you don't know the subject maybe its better not to comment, just a thought.

Thanks tinknocker you have been very helpful

The supply can is the supply duct! Don't bother trying to answer my question you are no help at all! I'm sure you are bald by now!

Excuse me truck! And FYI I hooked it up to the same wires it was hooked up to at the supply can. I assume that is correct. Wires ohm out ok. And in the trouble shooting guide that is what it says, if...

Your contractor is giving you good advice on the returns, try closing a bedroom door without a return and the fan running, you will find the door gets pushed closed by the positive pressure. Many...

The board is not the problem, the trouble shooting guide says its the controler thats located at the side of the board. With other 2 stage systems I have been fine with using Honeywell or Arzel...

Customer of ours has a harmony zone system. fault code tells us temp sensor bad, changed sensor, still not working, fault code says if still a problem change controller. Does anyone know if there...

If ARI doesn't list it there is probably no way to know

And lets not forget sub cooling for our txv friends

Ditto

I know you said it pumps down but it sure sounds like the valves are out. Your pressures are almost equil and the hissing noise sounds like internal bypass to me plus the hot compressor. If I can get...

Most manufactures tell you that you need to install a accumulater just before the condenser. The reason for this is liquid refrigerant will accumulate at the coldest point and with the lines being...

Glade to here I'm not the only one not afraid to not change line set, as long as we use micron gauge to confirm evacuation all is well.

The biggest problem you could have is having to adjust refrigerant charge between winter & summer. Heat pump coil match-ups are a lot more critical than straight A/C. All should be matced by the way....

Zoning is a no brainer, my big question is why is this guy trying to talk you out of it. Unfortunatly a lot of contractors are still afraid of zoning. also if you already have a zone system why can't...

Just to let you know, anytime the condensate pan is on the negative side of the blower you must have a trap or it will not drain untill unit shuts off. I agree that the dirty coil is probly the...

All system should have correct duct size, that statement makes no sense to me!

Ask for engineenering book from other register manufacture that you want. Thats the only way I know of.

Thanks for the info dash!

calibrate gauges using refrigerant temp/pres chart. Hook up gauges to refrigerant tank, if you measure temp of refrigerant you will know what pressure your gauges should be, adjust accordingly

beenthere,
Not to be disagreeable, but the tools I mentioned do not trouble-shoot for you, they just do it much more accurately and faster. A unexperienced tech can't take a set of digital guages...

Hope your joking "beenthere" we don't invest enough in state of the art tools already. I see you guys all the time debating friction rate, duct sizing ect. when there are great tools like computer...

If you want to make life a lot easier, buy computer design software, this will allow you to do room by room load calculations and duct design with air flow for each room!

Space Guard does publish its static pressure #s. Whoever you are buying it from should be able to tell you. I'll look for #s for you also. Just wondering if you are assuming 1400 & 1200 cfm just...

My point for screening contractors by those who do load calcs is this: what chance do you think a contractor that doesn't do them will even think about static pressure and manual D duct sizing,...
