    It might help to have a professional come clean out your furnace. Dirt and dust can build up during the year and your furnace may just need a tune up. Norah Chandler|

About once a week, I have to unplug the bottom end of the condensate tube on my high efficiency furnace and let the water out, then do a reset so the furnace will run. Why is this happening and how do I...

Condensate drain plug? New to me. Remove the plug and put a 5 gal. bucket to catch the water and remember to drain the bucket, so the furnace won't trip.
When hot plenum is not set hot enough, moisture will condensate on the heat exchanger. This moisture is acidic. It could be your hot plenum temperature needs to be raised to avoide frequent moisture problem.
By the same token, heating and air cooling removes moisture from the air and air needs moisture to feel warm or cool. Dry air is not desired.

Renting and Paying the Gas Bill

This past week I changed out an old hot air furnace in a rental unit that made me question why the tenant did not go to the owner and offer to pay more rent in exchange for getting the furnace changed out sooner. If you are a renter that is paying the gas bill, then you need to think about this.
The hot air furnace was at least 60 years old. It had been coal fired furnace that was converted to gas many decades ago. The pilot light of this beast was more of a torch than a pilot light. When the thermostat called for heat the flame roared for 15 minutes before the exterior blower unit that was added when the furnace was converted to gas, started up to move air through the furnace and into the house.

As I was starting up the new unit, which took up less than 1/3 of the space of the old beast, the renter came and sat down on the basement steps looking on in amazement. How would that little thing make enough heat for the house? A few minutes later those questions were put to rest very quickly.

After starting the new furnace and burning off the oil that always smokes up the house a bit on a new startup the new little unit had the house warm as toast and was shutting down. Wow, that took less time than the old beast took to just warm up!

The renter related to me how that the old furnace cost over one hundred dollars a month just to run the pilot over the summer months. The wintertime heating bills were many times higher than that. The difference between the bills of the old unit and the bills that will be coming now will be unbelievable. A savings of 40-50% is not at all out of the question.

Now, if you are renting and are paying the bill to feed an old monster of a heating system, I suggest that you make a proposal to your landlord. Offer to pay a bit more rent in exchange for a new heating system. Not only will you decrease your gas bills enough to pay some extra rent and still come out ahead, but you will have the peace of mind that you have a safer heating system under the roof that you also live under.

Heater blowing slightly warm air, but certainly not hot enough for pa winters. what should i try to fix first?

You may have to replace your heater core . Heater cores are kinda like you outside ac unit and if you stand by it you can feel all the hotter air blowing from it to the cooler atomosphere!!!! So basicly your heater core are alumminum fins that your blower pushes recycled heated motor air through', and into the cab . Maybe the blower is weak . Check your fuses and hoses!!!!

Intake vent needed?

The blower motor is only going to pull a certain amount of CFM for circulation air. There is some restriction of air flow that is created when the return air system is ducted causing the air flow to "slow down" a bit. The air going into the furnace firebox is probably moving at a faster rate than if the return air was ducted. It will work and you will get the same amount of heat (energy) released but the faster moving air will make it feel cooler. Also the unit might be undersized(BTU output) for the size of the cabin and amount of airflow the blower is creating. Adding a extra filter(double) might slow down the air flow a bit to create more warmth(feel) coming from the registers. Also if the furnace and air intake is pulling air from outside(garage,closet, or under house) then the colder air from outside going into the system will decrease the heat from the furnace. It is better to have a closed system (return air inside cabin). You might want to try adding a extra filter to slow the air flow down some or use some sheetmetal and square it from the intake to try and concentrate the incoming air a little better and see if that improves the warmth coming from the furnace.

I am having alot of heater problems.I just flushed the heater core out but still no hot hair its warm but not hot

How do the hoses going into the firewall on engine side under hood feel ? They should be reasonably same temperature. If one is hot, and other is quite a bit cooler, then you may have blockage still in core. If they feel close to same (hot) then blend/air door may be stuck. Can you hear things moving under dash when switched from cold to hot, and hot to cold? Does the air coming out get hotter if you rev engine a little and hold it there?

Air only gets cool and the heat only gets warm

Found this on another website from someone else with the same problem. Hope this helps.

"This is the second year for lukewarm air coming from heater. Last year I changed t-stat and add new coolant ,also new radiator cap. It helped a little but not enough. Took it to a mech. and had it flushed ,that seemed to help alot but not as hot as it used to be."

Air not warm enough

You need to verify gas input pressure with a gas pressure test kit and also check heat exchanger for soot build up.

Problem with furnace, air but no heat

the hot serface igniter may nead to be replaced again . if the is a lack of air
[ have this checked} getting to and frome the furnace it may be causing the furnace to cycle off the burner duing call for heat. it recycles back on and off untill the thermostat is saticfied. this means you are reusing the igniter more often the once a call for heat . therefore shorening it life expectancy.. make shure you are not blocking the air flows with over filtering ..whitch i have found to be the most common mistake . this and not changing or cleaning air filters often enough.
