Do not do this if you don't follow all the codes. The termination must be at least one foot above the peak, if it is within 4' of the peak. also it must be 4' and/or 10' from a rising wall, at least 10' from an operable window - search out local code. The instructions with the heater will...

flame sensor may not be proving flame (ground issue - on some models it is neutral sensitive 110v, quick test is to switch the hot and neutral at pig tail or disconnect) - or - Unit is overheating check the delta T...usually max is 50 F. Is there a blockage in the flue? Are there pressure...

Square D

Yep - Communicating equipment. In the early days I did use the simple mini split condensing units with conventional systems, all that was needed was installing a contactor. Those days are long past.

You really need to inspect the interior of that A coil. You might just be forcing more air across a fairly clogged coil. This is one of my most common older system service calls. Your A/C system was designed to deliver exactly the right amount of cfm (400 cfm per ton at .05 static)across the...

Dirt builds up on the other side...that (upstream) side can look great. You need to imspect the interior of the "A" coil. One side cleaned up

Yeah...They're walking away with ; spending how much on A/C pad, wiring, refrigerant piping, condensate piping, line set cover and all the other assorted parts 10 years liability if the owner has a lousy attorney and 20 if they have a good one. At least one year of free call back potential...

Check that the vent is clear, cap is intact etc

Not in this case...freezing is not an issue there and this cap will prevent what happened.

It's still open with this cap.

There's a simple cap you can use on any condensing furnace...we call it "the egg". It cleans up the look and allows clear inlet and/or outlet - (supco) ecap 321 PVC flue cap

BEST ANSWER everybody today seems to forget there is a value to hiring someone with trade knowledge and expertise in their field. Uh

Heat is the simple side of this equation...you can step down a heat system and most high efficiency units are dual stage anyway...low fire, hi fire. If you "up size" the cooling system you will find that the BTU of the furnace working with that system is greater as well. If you do this, the...

Pretty much 4' across the board.

You do need 4' of clearance above the condenser fan. There is nothing wrong with venting the new furnace up through the existing vent, but the new pipe must be inserted all the way to the termination (cap). As far as the various quotes are concerned, compare only apple to apples. single...
