The home I recently bought has a Lenox Conservator III G 16

The home I recently bought has a Lenox Conservator III G 16 and the configuration of the filters looks funny to me. There is a boxed out area at the left side behind the lower panel with 2 filters, size 16x25x1 in there and a piece of a 2x4. It looks like at one time the board was propping them up. It just doesn't look right. I want to make sure I am using the right filter, in the right place. Also, how often should it be changed? Can I put a high efficiency one in there? Thanks in advance!

Pearl! Happy New Year! Today heat was not coming on.

Hi, Pearl! Happy New Year!JA: Thanks. Same to you!Customer: Today heat was not coming on. Replaced igniter and it started working. Light is continuously on except between firings in the same temperature effort (eg, getting it from 67 to 69 if set at 68) when it flashed 4 times. Is that normalJA: Did you double-check the thermostat's settings? And what about the filters?Customer: Thank!JA: Do you plan on doing the work yourself?Customer: Not sure what is needed, seems that light is on 80-90% of the time. Should it be on 100% of the time? Thanks!JA: Anything else we should know to help you best?Customer: Changed air filter too even though old looked pretty good.

I have a question, and have been to this web page several

I have a question, and have been to this web page several times. I didn't ask right away because I knew I had to find a lot of facts so a good answer could be provided. I think I am ready to ask now. It is complicated, should I ask you or Matthew directly (no offense intended in any way), he seems to be online now.JA: I'll do all I can to help. How long have you been dealing with this?Customer: 10 yearsJA: Do you plan on doing the work yourself?Customer: I know my limits (I can put in ducts, fix ducts, and diagnose electronic / electrical problems and put fittings on gas lines) but don't want to mess around with gas if a pro should do it.JA: Anything else we should know to help you best?Customer: No, just have to add a description of the problem.

Furnace starts off with hot air and then after about fifteen

Furnace starts off with hot air and then after about fifteen minutes reverts to no hot air. Just pushing air through. American Standard guy said this was a new one. I question that. Thought it was a coil in the gas valve.JA: Did you double-check the thermostat's settings? And what about the filters?Customer: All of the stuff has been checked. Had my tune up people out and he was stumped on the symptom. There is not error code coming off the PCB.JA: Do you plan on doing the work yourself?Customer: Debating on what the cost of the valve is. Some places are ad $66 bucks, and others at $225 bucks for a VAL9030, which is supposedly the replacement gas valve.JA: Anything else we should know to help you best?Customer: No, not really, just trying to see if this is something you have seen and know of a solution.

Had two Goodman furnaces installed with two new powered

Had two Goodman furnaces installed with two new powered Aprilaire humidifiers that are not activating when either blower, induction or main blower, turn on. Since I had the older 110 controls mounted in the return ducts, we decided to use them instead of connecting the digital controls with additional wiring instead of the 6 wires (24VAC, A/A and temp sensor) on the older control. THe installer (in the spring) hooked up the solenoid leads to the HUM in and HUM out connections on the Goodman, ran the thermostat 4 wires to the proper terminals, and ran the A/A to the C and the jumped Y1 Y2. If I am reading the instructions properly from the older controllers, this doesn't appear correct. Any suggestions?JA: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?Customer: No, the units have worked perfectly from April to now, and continue to do so. Both units were wired with the new Aprilaire and neither operate properly. THe instructions that come from Goodman are quite vague, specifically when they indicate that 24 VAC needs to get to the HUM in. Does that mean wiring from the R to the HUM IN? Then does the Hum out go to the solenoid? Where does the other lead from the solenoid go?JA: Do you plan on doing the work yourself?Customer: I usually can troubleshoot something like this myself, but I like to have clarity of instruction from the manufacturers and a reasonable schematicJA: Anything else we should know to help you best?Customer: Nothing that I can think of at the moment

Questions you might consider asking
  • My AC unit is struggling to get good air flow out of the vents and not cooling well. The copper line on the outside part of the unit. I changed my air filter this morning and left the unit off for about 6 hours and still no luck. Do you think my coil is frozen?
  • I have Model #FB4CNF048. Where is the air filter located and how do I change (or clean) it. The return air appears to go back directly into the unit unfiltered.
  • Where is air filter location on a ruud model ubhc 14j00nfa
