If your furnace is not working properly, you may have to consider a furnace repair to help fix the problem. There are several different issues you can have with your furnace, and they include: carbon monoxide leaks, rotten egg smells, and a safety switch on the furnace door that does not work. Having a trained professional inspect and repair your furnace is important, since if you do not get it fixed right away, you could experience serious problems.
rotten egg smell in furnaces
If you smell rotten eggs in your furnace or home ducts, you should turn the furnace off immediately. The odor is caused by sulfur-reducing bacteria that feed off sulfate, a naturally occurring ion in water.
Gas-powered furnaces often emit a small gas odor when they are first turned on. This is because the furnace is pulling air from outside to heat up the inside of the home. The odor fades away as the dust and dirt are burned off.
The best way to determine whether you have a leak is to shut off your furnace, then open your windows. If you don’t have time to do this, you can call your local utility company to report the problem. If yours does have a leak, leave your house while you wait for help.
fan won’t shut off
If you are having trouble with your furnace fan not turning off, there are a few things you can do. There are some easy and some complicated solutions.
The first thing you should do is check your thermostat. This device regulates other parts of your HVAC system, including your furnace. You should have your settings set to AUTO if possible. This will automatically shut off your fan when the temperature reaches your desired level.
The second thing you should do is look at the fan limit switch. This is located under the hood of your furnace and serves as a safety feature. You may need to replace it if it is malfunctioning.
The thermostat can also cause your fan to run continuously. Make sure it is not set to a high setting. This will strain your furnace and will result in higher energy bills.
carbon monoxide leaks
When furnace repair work is done, it is important to pay attention to carbon monoxide leaks. If you suspect a leak, evacuate the home and contact a qualified HVAC technician. A leak in your home can cause long-term health problems.
There are a number of reasons why a furnace may leak carbon monoxide. The most common reason is a cracked or corroded heat exchanger. This is a metal part that expands and contracts depending on the furnace’s heat. If it is cracked or corroded, the gas will leak into the home.
Another reason a furnace may leak is due to improper ventilation. If there are holes in the vents, carbon monoxide can build up in the home. If you have an older furnace, it is more likely to have a crack in the heat exchanger.
Safety switch on the furnace door
The furnace door safety switch is a very important device on the gas furnace. It keeps you safe from toxic fumes that can circulate throughout your home. The switch will also prevent loose materials from getting pulled into the burner or blower.
The door switch can vary in shape and size. If you are replacing the switch, make sure that it is the correct one for your furnace. You can find this information in the owner’s manual. Some models have universal switches while others are made specifically for specific models.
To access the switch, you will need to remove the cover. The cover will usually have plastic knobs that you can turn. You may also have to use screws to pull the cover off.
Replace an old, inefficient model
If you have an older furnace, you might want to consider replacing it with a new, more energy efficient model. This will help keep your home warm while lowering your utility bills.
A good way to determine whether you should invest in a new furnace is to consider the size of your home. For instance, if your home is a small one, you may be able to save money by installing a furnace that has less capacity.
You can also use the newer sizing software to determine whether your current system is the appropriate size for your home. If you decide that it is too big, you can modify it to fit your needs.
A good rule of thumb is that if your furnace is more than 15 years old, it is likely to be inefficient. An inefficient model will cost you more in energy costs, and it might not be worth the extra upkeep.
