Mine is not a Trane but it came with a CCH.

American Standard has demand defrost. That means it only defrosts when 2 sensors and the logic in the defrost board say it is necessary. As far as I know, Amana has a timer that will defrost if the...

The Econet control is great for the communicating furnaces. We sell mostly 97 & 98 % furnaces for the tax credit. But the 96 will work fine with t he Econet control. It will run like any single...

Ruud has demand defrost, Bryant uses a timer. LOTS of unnecessary defrosts with a timer. I've had both so speaking from experience.

Ruud also has a louvered cabinet, Bryant does not.

Only...

What's the radiation? Big old radiators are great for a mod con 90+ gas boiler but there is some savings if you have fintube. Do you know the price per gallon of oil you are paying? How about a therm...

Also, since you measured the radiation, convert it to BTUs. No point in having a boiler bigger than the radiation can put out. It will just cycle on limit.

Who makes the Comfort Pack?

Our detectors don't read that high. They will shut down to protect the sensor. Other ways of telling there's a problem is top front of furnace is hot and furnace not heating the space. A customer...

We sell a lot of Rheem R98 furnaces with the non communicating 16 or 17 SEER outdoor units. The Econet control is a bit flimsy but lots less loot than most communicating controls. Rheem is made in...

It may have been a high end unit. Regardless of brand, out of warranty parts are pricey.

Second that. I have that stat and love it. No glitz, just does it's job and stages my heat, does the dual fuel, does dehumidify on demand, averages temp between control and remote sensor. Oh, and...

Seems to me they make it or own the rights to it or something like that.

Actually 32 is in 454B

Lennox A/C is a builder model. It is made in Mexico. The furnace is the deluxe (Elite) unit made in Marshalltown, IA. The original Dave Lennox factory.

Brands? A&E will service GE Zonelines and handle the warranty since the sealed system has 5 year coverage.

A good tinman can do that easily. A lot of jobs we do have the 33-34" tall furnaces taking out one much taller.

Friend has a mod with the 411 stat and a Bosch heat pump. Working good.

Model numbers? Make sure you compare like to like and not 1 brand's premium line and the other's builder models. If you're looking 2 stage more likely to get a nicer unit.

Looks like my numbers....

Sounds like it.

That must be some antique. I don't recognize the model #. You're looking at some bucks to redo the gas valve, I'd sure recommend replacing.

I'm not waiting. By next summer I think I'll give the heat pump a nice going away present and find something else before 410 is gone. These units don't have 10 years of field use like 410 did when 22...

I don't believe that today's Econet system works on the older units. I think you'll have to go 24V

Carrier has some money in Midea, that probably explains them working together in small minis. VRF units are someone else, Toshiba maybe?

If you want what the communicating systems are capable of, you don't want the TEM6. Go for the 9 if you can. Why do you need a new air handler? Is it matched to the heat pump?

Personally I'm a Trane/American Standard fan. Seem to be the most reliable (far from perfect) we tend to see and they also are rather quiet. We sell Ruud, a Rheem trademark, they can get rather noisy...

If you're low on charge, the EEV could be wide open to try to get some cold gas back. If it can't, you freeze up. Not much diff than a TXV.

Duracurve? I thought it was Duracrack?

EVERYTHING is way up. I was thinking of a new car (or even used) but $35K for a Camry or Accord is pretty salty. $60 for 2 bags of groceries at ALDI is nuts. Dealer direct costs and overhead...

Ruud

Ask about the 98 modulating furnace with the econet control. Amazing comfort. Otherwise, the 96 is a well built furnace too.

A friend put in a Bosch. I looked at the heating numbers, HSPF and capacity and didn't see much difference to say an average 15 SEER unit. The Bosch is not a "cold weather heat pump" like some of the...

I think you'll find A coils easier to work on than N coils.

Then there's Carrier's Micro Channel V coil. No thanks. Had enough MC coils leak when we sold some Nortek stuff.

Sounds pretty normal. Boiler likely oversized for the radiation even if it is fine for the Manual J. With baseboard, usually see high limit set for 170-180 degrees.

We sell a lot of Ruud. I just did an after install inspection on a couple A/Cs. Complaints? Noisy outside and the compressor pressure protection switches are optional. We sold Rheem for a long time...

I'm crunching one of the boss's jobs right now. We analyze each job carefully. It was a 5 to3 drop.

The furnace is made by Rheem so a good product IF properly sized and installed.

I helped a friend put a Bosch 15 SEER on his old Rheem modulating furnace. That is a neat heat pump but even at...

Since most duct systems are undersized for what you have, going notably bigger and not adding a number of supply & return ducts is not good. Double whammy if a new home contractor did it orriginally.

Do they need gas from a leak? If not, I'd leave it alone.

Way back when, Carrier did that on residential too. Confusing and probably led to undersizing without knowing it.

Not sure how much Mitsubishi makes in Japan. I think you'd find it little to none.

Many American names manufacture in Mexico and that will be increasing.

Remember cold air calls so if the MBR is set to 64, a lot of that cold air is falling downstairs. 64 is too cold, that can cause condensation in the walls. Also could cause a coil to freeze though...

Not sure of any sleeves but a good carpenter could have that GE in rather quickly. The old PTAC needs its refrigerant be recovered before it is disposed of but a carpenter might not know that.

Got a model # for the old beast?

Varies. Period.

Depends upon outdoor temp, indoor temp, indoor dew point (aka humidity) how oversized the unit is...

Back in 1971 my Dad was tired of being warm in the house so he went out to Sears and asked for the biggest window unit they had. Turned out to be 2.5 ton. We only had a 60 amp fuse box so had to turn...

I've got a book at the office that tells size of relic units. I'll take gander tomorrow. Can't remember the last time I saw one of them .

Best way is don't worry about what's there but what SHOULD...

Got a model # of the Arco? They have several grades of equipment so need to confirm which unit being quoted to see if it compares to the AS, which doesn''t have lower end, they have RunTru for that.

Gets confusing. I was doing a post job inspection on an A/C. Model # 4A7A5036 which would lead you to expect a 15 SEER2 system. The yellow sticker said 13.4 SEER2 which really confused the HO. With a...

Day & Night are both Carrier products. Obviously the Day & Night is a superior product in efficiency and the 2 stage compressor.

Both the new Rheem/Ruud 14 & 15 SEER 2 heat pumps are also 2...

A/S and Trane have multiposition 80s. If you don't want it that way, in some installations you can get a kit to run the flue out of the top. Solution 2 is what we do in this case - sell our other...

Any ducts in a warm, unconditioned space? Usually see that with attic ducts that are picking up some of that very high attic heat. I remember a call years ago where I found a perfectly working system...

12 subcool doesn't sound bad to me but every unit is different.

The temp drop can vary based on humidity. Sticky out you will have a higher latent load so your temp drop, which is sensible heat,...
