Heater problem model PHK 080-1

Few weeks ago i noticed a burn smell coming from the heater on the house, it smell like the first time you turn the heater on in the winter and it burns the dust or hair trapt on the coils during summer. and i noticed a lower flow of air coming from the unit. it does blow a little heat but not suficient to heat the house. i did check the filters and i did not change them for 4 months (ups....) i was thinking that the coils on the heater are chocked with dust and dirt, (since i did not change the filters sooner and because of the burn smell) however this morning i turn the unit off and turn on the fan only, and it did not came on. i check the brackers and all of them are O.K. (2 for the A/C and 2 for the Heater. out side the house by the unit, and 1 in the box where all the brackers fro the house are) at this point i am thinking that a fan may be the problem, but i am not sure. do you guys have any ideas on what i may do. thank you.

You should look in the air handler( Where the indoor blower is located) or in the plenum (where the duct system originate at the air handler) for any dead and rotting rats. Residential central air systems are sealed (uses circulated air only) and do not use outdoor air.

To make sure that there is not a problem with your blower test it on cool. if it runs good. then start the heater on auto and it should be okay. but still supervise the operation for about 5 mins. if you still smell something burning . then call an AC Technician for help.

Heat pump was on and the smell burnt resistors coming from ducts

A burning smell could indicate an electrical problem (something overheating) or, if the unit has electric strip heaters that have not been energized for a long time, the buring smell could be the dust burning off of the heaters.

I would have a tech come out and check the voltage going into the fan relay and fan itself. The smell being as how it is coming through the vents in the house tells me that the problem has got to be at the blower or in the area at the blower fan which leads me to the possibilty that the smell could be the windings on the motor. This could be because the voltage may be to high. Good luck on repairs

I'm going to guess that there is something in the heater area which doesn't belong there.  It might be insects or worse.  Get someone else in to look at the burner/heater unit.  The other problem could be a stuck fan which is burning...although that usually starts as a squealing bearing.

Burning smell from AC Unit

"Odor problems can be as serious as a gas leak or as simple as a dirty air filter. But remember, a good mechanic doesn't just use his hands. He uses his ears and nose. Unusual odors could indicate a serious problem and should not be ignored. 

We will go through each of the five categories and list the possible causes and things to check.

1. Electrical odor - Electrical odors are usually caused by parts overheating. Indoor blower motors are a common example. If there is a mechanical failure such as the bearings seizing up, the motor over-heats and the insulation on the wires and the motor windings themselves start to melt, causing the odor. 
Sometimes loose electrical connections cause wires or plastic relays to overheat causing electrical odors. 

It is possible for a very dirty air filter to cause the odor. If the airflow is restricted enough, it could cause electric resistance heaters to overheat, even burn-out. 

If you smell an electrical odor, check your air filter. If it is not blocked, shut off equipment at the breaker if possible and call for service. 

2. Burning odor - This is similar to an electrical odor only worse. It is also sometimes accompanied by smoke. Once again, this can be caused by parts or wiring burning-up. 

It can also be debri such as plastic getting into the ductwork and melting on the electric resistance heaters or heat exchanger. 

If you smell a burning odor, check your air filter. If it is not blocked, shut off equipment at the breaker if possible and call for service.

3. Gas odor - First of all, if you really smell gas and suspect a gas leak, you should open the windows, get out of the house, then call the gas company. 

Now excluding that "worse-case" scenario, if you notice an odor that smells like gas and it seems to be coming out of the supply vents, it usually isn't gas. Sometimes dust that settles on the heat exchanger during the summer months burns off at the beginning of each heating season and it smell just like gas. 

If the odor doesn't seem to be coming from the vents, try to pinpoint where the smell is coming from. Use your nose. If it is gas, it usually would be from a leak in a pipe fitting or at the equipment itself. 

Gas odor is the one that causes the most fear. People think of gas explosions or carbon-monoxide poisoning. Well, gas explosions are very rare and carbon-monoxide for the most part is odorless. 

Having said that though, don't take a gas odor lightly. If you can't locate the source of the odor and you are worried you have a gas leak, remember, open the windows, get out of the house, then call the gas company. 

4. Oil odor - Oil odors are usually caused by one of two things. An oil leak/drip or an oil burner that is not working properly. 

The oil leak is usually easy to spot. Just look for oil. Check the burner itself, the oil tank, filter and oil line. Sometimes it is just a matter of tightening a fitting. If there are no signs of an oil leak then it is most likely a burner problem. 

This can be caused by many things, too many to list. It could be a minor adjustment to the burner to a faulty or blocked chimney. From a bad fuel pump to a plugged oil nozzle. Listen for any unusual rumbling or banging sounds or smoke or soot while the burner is running. If you notice any of these things and/or you have an oil odor, you should call for service immediately. 

One other common problem today is that new houses are insulated so well and are built so tight that they run out of combustion air, causing odor problems. In this case it is just a matter of bringing in a fresh air for the burner. Call your local Heating Company to assist in a proper diagnosis. 

5. Damp and musty odor - This is more common in the air conditioning mode. Sometimes attic units or very damp basements have this problem. Check for air leaks in the return ducts. Check for water damage to the ducts or air handler itself. Possibly consider having your ducts cleaned. Run a dehumidifier and see if the odor goes away. 

But this odor problem is almost never due to a problem with your equipment. 


Final Tips:

Keep in mind that almost all heating systems cause an odor the first time they are fired-up. And the first few times at the beginning of each heating season. Brand new furnaces are coated with oil to keep the heat exchangers from rusting. This burns off, creating a bad odor - even smoke. But it usually only lasts for about 20 minutes. Opening the windows usually solves the problem. And the first few times the backup heat on a heat pump kicks on, it smells like an electrical smell. This might last for a few days but isn't that bad. If you are worried, call for service. 

Remember to check for a clean air filter and that your vents are opened. Check to see if the fan is working which mean your motor hasn't burned-up. 

Check for air leaks in damp areas, oil stains or rumbling sounds, strong gas odors - these all indicate problems. Do not ignore them. 

Hope this helps, remember - these are just rough guidelines and not all possible situations are covered."

Goodman Heat/Air unit Model # A49-20 Serial # 9909502720

It sounds like the blower motor has burnt up.(the one inside) The unit running for a few minutes then shutting off, is due to the high pressure/temperature safeties. When you removed the panels, did you notice any fan running?

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.

Strange smell

Have you cleaned the evap coil? Most often smells come from the evap coil. A bleach type product used for cleaning will solve this problem. Thanks
