Can you usen the sam air vent for heating and swamp cooler

Yes you can. I have that set-up in my house. The only problem is when moisture laden swamp cooled air goes past the heat exchanger. This could cause the exchanger to rust out, allowing carbon monoxide to come into the house when the heater is used. This can be avoidid by having a one way damper made by an HVAC shop, and installing it at the heater.

Can the paramount patio heater be used inside the house in the winter if you don't leave it on when you leave the room

If it is gas absolutely not! Not familiar with this particular unit but if it is a patio heater it tells me it is kerosene or gas. Here is the thing with either one. You have to have a constant fresh air supply to get complete combustion. When you don't get complete combustion you get lots of carbon monoxide. Carbon monoxide will kill you!
Hope this helps

I have black soot coming out of my gas wall heater and the vent on the roof is all black too. Not sure the age of it, could be up to 50 years.

You need to have a service company come in and service your heater. #1 it needs to be cleand. #2 They need to do a thorough check out of your heating system. I can not stress this enough; your flue and heat exchanger are blocking up and you are at risk for carbon monoxide poisining.

Why is my 1987 3ton gas package unit keep cycling on and off it will only get house about 65 i have cleand all the return even the coils inside it,it has new exhaust and blower fans,seems to be...

Check for dirty filters, blocked off return and/or supply registers, restrictions in ductwork and most importantly, ensure you do not have a cracked heat exchanger.......make sure you have a carbon monoxide detecter < 5yrs old located in your main living area and in your bedrooms.

Hope this helps and good luck!

My heat will not cut on when I put it on "auto". When I tried to see what would happen when I put it on fan, cold air started blowing out. It is 30 degrees outside. Please help.

ok here goes. Do you have electric heat, if so, then it is possible that you heat strip has burnt out. If this is the case you will need a new strip installed by a trained tech. If it is a gas heater you will need to have a tech come out and repair the unit due to possible carbon monoxide poisoning very important here on this. Sorry I couldn't give you better instruction but your problem is a little vague.

Carrier 48ss-048120341 propane unit smells bad, smoking. think the heater tubes may have holes in them. how are they removed, can they be replaced, can I braze holes if found

First recommendation. Turn off the furnace, and buy some carbon monoxide detectors. I definitely do not recommend you using the furnace without them.

Yes, the heat exchanger can be replaced.
No, you would not want to attempt to braze the holes.
If the HE is cracked or has holes, it needs to be replaced. That can kill you.

They are usually removed by disassembling 90% of the furnace and part of the cabinet. This is a major repair, and not a do it yourself issue unless you have some experience and training in the operation of furnaces and electrical controls.

Also be aware that your HE may be under warranty depending on the age of the unit. Most are 10 year warranties. Some are even lifetime.

Coleman Evcon Furnace Model G8T10012UHB11A

you probably have a cracked heat exchanger which is causing the rollout switches to trip.even the tiniest of cracks will cause the fan to blow the flame back into the unit and cause them to trip. check the heat exchanger for even the tiniest of cracks if so replace it. and be sure to have a carbon monoxide alarm in your home.

Smell gas through vents when furnace is running

I would strongly suggest a carbon monoxide detector first. Also your gas provider should do a free leak check. This is nothing to play with.

Intertherm furnace explosive burner ignition

Cheman, yes this is a real problem. Not only will it get worse, it could kill you and your family. If there is a blockage inside the heat exchanger where your technician could not reach, you would not do much better and may cause more problems if you do. If you continue to run this furnace, you will create Carbon Monoxide and it will kill you over a very short time.

Stick with yor technicians recommendation and get a replacement unit. Go with a direct vent unit and a higher efficiency than this old clunker.
