That shorter limit could be the cause of your furnace catching fire at a later date!

I have seen nothing that would indicate that either style of HX would outperforn the other for heat transfer. Tubular heat exchanger will often times allow for a smaller cabinet size though.

Any good HVAC technician should be able to seel those gaps up for you with sheetmetal in order for a standard size filter to fit

If I try to use mine near anything shiny all I get in the center of the monitor is glare! There is light, just a wavelength that the human eye doesn't see and is subject to all the problems with...

You're having better luck with your "inspector" cameras than I am. Fixed focus unit can't see anything up close, manual focus unit, nothing but glare upclose. Have to check any questionable areas...

I'll add my penny's worth. Never trust to just one meter. Stuff happens in the field! A good quality clamp meter and a good quality multimeter are minimal. One of these has to be capable of...

In your system the infinity control determines the required airflow and allows very little adjustment. The heatpump alone will be very slow to recover from setbacks. To alleviate this I would raise...

Been using one for about a year, they will go through some chemical though. Take the foamers off and toss them, the artifically generated foam doesn't penetrate well but the chemical/water steam goes...

Zoning is better than nothing! 2 systems is the better route!

As GAMA says on their website, if it's gotten wet, replace it!

I have a problem with using the ADP coil with a Trane or AS. As a rule ADP's coils don't have as much capacity as Trane/AS condensers and significantly shorten then lifespan of their compressors. I...

My thoughts exactly Beenthere.

Possible that the termidistat is configured or wired incorrectly. Maybe a couple of wires that got shoted together somehow.

Don't worry it'll quit again! Do yourself a favor and call someone to come out and give it a proper cleaning and check the system over completely.

As long as it is just frost don't worry about it. If your old Lennox HP didn't frost in the same manor it was probably overcharged. Since it was forming frost at 55 degrees it is probably slightly...

The physical size of 13 SEER equipment will be decreasing very soon due to some new coil and motor technology. some manufacturers are preparing to rollout some 13 SEER equipment that is physically...

1.) something has happened that the heat pump is no longer providing heat.

2.) If the heat pump is not heating then set the stat to emergency until it can be looked at by a qualified service...

The U/V light will actually break down "most" organic substances if they are exposed long enough. It will also destroy some of the cheaper made evaporator drain pans in the same manor.

If installed where they can shine on the evaporator coil they are great at keeping it clean but do little else, unless the design incorporates some method of slowing the airflow, and concentrating...

Agree totally with Toolpusher but I would always change out my own lineset as cheap insurance against contaminants getting in the new system from the old.

Having played this game for a number of years. You most likely will not notice the difference between the 2 in utility savings. There are many variables involved in the installation of a furnace that...

I think I've replaced 2 of them since Trane started started using silicon nitride

Oh how wrong you are sir. Having participated in online forums since the days of the old BBS systems before there was widespread internet access, this is an extension of the sysops/moderators home....

The 80% furnaces are definitely noisier inside the home due to their open combution chambers and in most cases the cheaper bearings used in their draft inducer motors.

Placeing the coil on the return side is correct. If on the supply side the heat pump might not like haveing 100 plus degree air blowing into its indoor coil. The furnace should be running while the...
