Geo is green because it uses less energy than other forms of heat (except solar). Drilling has the potential to do harm in areas by mixing under ground salt water with fresh water aquifers but a good...

There's no regular system when sizing duct. The 3-ton and 4-ton need different air flows and will require different size ducts. Even two 3-ton units can have different size ducts because they...

Ton is a term left over from the ice house days. Imagine the early days of refrigeration when cold storage was converted from ice to mechanical systems. An operator knew how many tons of ice they...

For sale used car. Great heater!

The 4 ton won't be over sized because it's a two stage unit. In fact it'll spend most of its time operating as a 3-ton and then upstage to a 4-ton when Btuh demand is high. The geo will feel...

A bunch of the geo units I service are from the '80s some vertical loop and some open loop. Some of the units have out lived the companies that made them. I just went on a call for 5-ton Jacobsen...

I've used a geo unit with the Evolution system which is the same thing. You'll need the network interface module SYSTXBBNIM01 (Bryant #) so the Infinity user interface can control the geo unit. The...

Yes they're made by ClimateMaster but you have a choice of blue oval or red chevron tag because they come shipped with both in the bottom of the cabinet. We sell a lot of the GT-PXs and there's no...

Have them supply you with a copy of their Manual J report and the design loop temp. It'll show a sensible and latent load for cooling. The sensible controls the house's temp. the latent controls...

Just read in your post that min. EWT is 50. You may lose capacity or you may get liquid back to the compressor depending on how conservative or exact that spec is.

I'm not familiar with McQuay products but I remember on the old WaterFurnace units the extended range units had a TXV instead of a cap tube for the expansion device. It maintained superheat at the...

I think one of the biggest differences between the European and US heat pumps is that the US units are reversible providing heating and cooling with one unit. Our heat pumps could be sized to cover...

I've actually ran into a similar problem. I didn't install the system but I did have the job of fixing it. The system worked for years then one summer the loop temp sky rocketed. We dug up the loops...

Aux heat allows you to put off that Christmas Eve service call till a more convenient time. My customers will call me at night with a problem but will ask me to come by the next day rather than pay...

Sound like your looking for a passive cooling system. They where popular here in PA during the 80's. They basically ran cold well water through a hydronic fan coil. They were good at providing...

How effective is the passive solar? Is the heat pump mainly there for cooling and supplement to the solar? You might want to consider a multizone ductless system.

Fuel cost play a big part in your rate of return. When oil was selling for $4.00/gal this past year here in the North East the ROM was pretty good. The Geo equipment is usually higher in cost then...

I think the term Geothermal started being on ground source heat pumps in the late 70's or early 80's? GSHP where being promoted as geothermal to take advantage of a Fed tax credit that applied to...

Typically houses that use a Geothermal are all electric. An 80 gallon electric will catch more of the free hot water off the desup. compared to a 50 gal gas, but I know I have at least one customer...

I don't know if Bryant has much info on their public site. All of the tech stuff is on HVACPartners.com

Here's some of what I have hope it helps.
FE4ANF003: slope coil, 3.46 coil area, bottom or...

I agree that you won't know if you'll get a decent pay back without an operation cost calc. The 2-stg will provide more comfort due to the longer run time. Is the compressor a 2speed or Copeland...
