@ March 5, 2014 12:43 PM in Gas furnace v hydro-air in remodelTrane 60K 95% furnace will be GROSSLY oversized for 1000 sq ft built like a tank. I have 1000 sq ft stand alone house and heated at -15° out with high locked out or firing at 36,000 BTU. Friend with a foamed 1600 sq ft house had a Trane 60K 2 stage and it would only fire on low with 2 zones calling, She never did use the basement so the zone panel wouldn't let the furnace go to high. So if you go with a gas furnace, find the smallest you can get or you'll short cycle so much you lose efficiency. Or another selling point for the hydroair.
@ February 26, 2014 1:58 PM in Single stage, two-stage and multi-stage, which oneWe've sold 2 stage furnaces for 30 years and modulating since Rheem came out with theirs. Customers love them. Never heard customers rave about a furnace til the Rheem mod on the matching stat. It is NOT gone now, just not available in the downflow and horizontal at this time. The new line they haven't brought out the multiposition mod yet. AFUE rating issues I hear. We put all of our 2 stage on 2 stage stats.
Only thing I'd worry about with 2 stage and mods is ceiling vents. Since almost all of ours are floor, even with downflow equipment, we haven't had complaints about comfort on low fire. As these new junker homes with ceiling vents need new furnaces, it could become an issue.
As for blowing cold air, since most furnaces start blowing as soon as a hint of warmth builds up in the HX, that likely will be an issue with any high efficiency furnace. A properly sized 2 stage with 2 stage stat will have long run times on low in bitter weather eliminating a lot of the cycling from the older, likely oversized single stage furnace.
@ February 19, 2014 4:05 PM in How to vent oilNew owners of an office in an old house. Took down the chimney venting the furnace. Got b-vent, stuck it out the side wall of the basement and terminated below the eave. This is what we found!
@ February 19, 2014 4:03 PM in atmospheric boiler for coach house?Never heard of that particular boiler and if it says don't put in a garage, it shouldn't be put in a garage. In our area, in a lot of parts of town, most equipment is in a garage regardless of what it is. No new boilers are being installed but the average smaller new home gets an 80% furnace and thousands are replaced each year. Many 90s in garages don't have outside air for combustion. Not putting an open flame in the garage may be a local code but if it is acceptable in an area I can't see how a contractor is risking his license doing it. Same with water heaters. Now they have the flame safeguard but are still using garage air for combustion.
@ February 19, 2014 12:44 PM in 007 capNow I know what to ask for.
If I can get this old girl a cap for a reasonable amount sure beats many many hundreds for a new pump installed.
@ February 19, 2014 12:41 PM in atmospheric boiler for coach house?Can't use a conventional boiler in the garage? That a local code? There are oodles of homes around here with boiler in the garage. For the outrageous price of a mod con with the extra piping, nobody wants to spend that. We go back with an 80% cast iron boiler. No problems here doing that. Just get the burners 18" up like we would with a water heater or forced air furnace.
@ February 18, 2014 10:00 AM in 007 capAnybody know where I can get this 5mfd run cap out of a 007? The usual blower motor caps don't fit in that little compartment.
@ February 14, 2014 2:44 PM in 007 CAPAnybody know where we can get just the capacitor for a 007? Seems a shame to install a new pump for hundreds when all it needs is a $1 cap!
@ February 13, 2014 2:25 PM in Replacement condenserAfter that first spike, how are pressures in heating mode? Mismatching is more likely to cause problems with HPs in heat mode since they need less charge to begin with AND the older indoor coil is physically smaller than the ones designed for today's units. So not unusual to run high heads in these situations though it would be all the time, not just on startup.
Is there a built in drier and a liquid line drier? If so watch that little toy Goodman usually puts IN their units. Doesn't take much to plug up.
@ February 13, 2014 2:19 PM in Condensing Furnace questionsIf heat loss is 74K and they go with a 100K 92-95% furnace, I'd call that oversized and sure wouldn't do it. Just my 2 cents worth. I'd find a furnace closer to the needs of the house. I would agree that the 80K is right. We sell mostly 2 stage and occasional Rheem modulating furnaces and our customers love them. Rare to sell a single stage except in rentals and lower budget situations.
Today's 95% furnaces want to move a lot of air so oversizing can be noisy if the ductwork is designed for 100° temp rise of oil!
@ February 13, 2014 2:04 PM in Nest Or other Internet controlled.I hate them and their support!
Ecobee is harder to use than Honeywell but tells you a lot more online. Honeywell stats are so easy but you are limited to simple alerts, changes and programming online. The Focus Pro WiFi is a pretty low priced way to get remote access.
@ February 10, 2014 7:52 PM in Laars low water flow boardGot an old JVS-100 found cool. Would fire for 30 seconds off for about 2 minutes. Regular as clockwork. Traced it to the low water flow board.
NOW: when it wasn't firing the relay on said board was clicking on & off like a turn signal. The whole time. And when it did it sent a split second of voltage to the spark control which in turn sent voltage to the gas valve so one of the solenoids in the valve, guessing pilot, was also clicking on & off like a turn signal. Obviously not right.
So, do we have a flow issue? Bypassing the board to get heat on a below zero night, sure doesn't seem like it. Got the loops hot in no time so didn't appear to have a flow problem. Hate to order a new board to have it do the same thing (less the turn signal). Just started this.
Any thoughts? Thanks!
@ January 28, 2014 1:06 PM in Difference in aquastatsThe current one and the -1299 both have the damper plug and our boiler has a damper. Would we be best going with the -1265?
@ January 27, 2014 4:26 PM in Difference in aquastatsAccording to Bryant it is a 433-00-523
(ECR part #) which appears to cross to a L8148E1257. So the question would be, does anything cross to that, such as the -1299 I have in stock, or do I have to go back to Bryant/Carrier/ECR?
@ January 27, 2014 8:47 AM in Difference in aquastatsAnybody know the difference between L8148E1165 and 1299? Will the 1299 work in place of the 1165?
@ January 21, 2014 12:35 PM in OldieBrand name we found was Heat Pack, made in Wyoming IL. Didn't look at the piping close enough. Just looked at one rad whose cover was off. Saw the vent.
@ January 20, 2014 6:25 PM in OldieFound this in the cellar today. May have heated the whole house at one time but in its last years, heated an area above the garage some distance away. New owners say hasn't been used in some time. Asbestos just falling off the pipes. 2 pipe but saw a vent on a radiator, thought they were only used on 1 pipe.
@ January 17, 2014 2:30 PM in Will the combustion exhaust from my condensing gas boiler harm my home's brick outer wall?The exhaust should blow straight out from the house, not elbow and blow along the house where it will damage the mortar and possibly stain the brick.
@ December 31, 2013 3:25 PM in Recommended steam thermostat with wifi and remote sensor?The newest Honeywell Vision Pro with EIM and Prestige IAQ have remote sense capability, wired or wireless. You would use the Redlink Gateway with either to connect to your web router. Overall I've found pretty the Redlink technology pretty reliable. Did have my gateway not tell the stat to put the fan in the on position the other day but that's been it.
Nests have been a thorn in our side, especially on heat pumps. Don't have enough boilers around here to know about how they get along.
@ December 27, 2013 3:35 PM in Trane xe 90If that has the Intell-ignition board, flashing 4 with no limits open is a common failure of the board. Replacing the board solves it which apparently he did. But why the blower motor? Was it really bad?
Those are great furnaces. Rare to lose a heat exchanger but can happen. HX has a lifetime warranty so lots cheaper to replace it than new furnace. We're more likely to find cracked secondary header than crack in the primary cells of them.
@ December 19, 2013 12:10 PM in Professional opinions neededThe heat exchanger would be under warranty. You'd have labor to pay but that would be 1/3 or 1/4 the price of a new high end furnace.
Are they sure it is the secondary header leaking? The transition between the secondary and the inducer likes to crack. They are cheap and easy to replace if necessary.

There's a "find a contractor" option on the menu line. I think you missed it and clicked on the ad that appears at the very top.
