Everyone wants heat when old man winter arrives in the fall. Many times we take it for granted that when the temperature falls all we have to do is go to the thermostat and turn the heat on. Usually, this is not a problem. We turn the thermostat on and the heat comes on. Whether we have boilers or a furnaces at the beginning of the season when we do first turn the furnace on we have a slight burning odor which comes from the system. Usually, many of us ignore this odor because it does eventually, usually, go away. This is normal and is usually dust particles that have accumulated on the furnace’s heat exchanger burning off. How many people actually think it is carbon monoxide and called a professional HVAC technician to make sure it is not a problem? There are some people who do call but a majority of people just ignore and enjoy the heat being produced by their furnace. After all, carbon monoxide is a colorless and odorless byproduct of burning fossil fuels so even if an unsafe condition existed with their furnace they would probably never know it. This is why it is important, before old man winter arrives, to call a professional, qualified furnace technician to inspect the furnace. First, the furnace technician can make sure that the furnace will start and second of all the furnace technician can make sure you will have a safely operating furnace. You want to make sure the furnace does not have a cracked heat exchanger and a good qualified HVAC technician will look for a furnace cracked heat exchanger. Heat safety is paramount so have your furnaces inspected immediately for a cracked heat exchanger. Have a safe heating season.
Residential and Light Commercial Low Pressure Steam Boilers
The residential steam boiler is still alive and well despite the fact that some HVAC professionals refer to it and the steam boiler profession as the dead mans club. However, there are not a lot of HVAC boiler technicians or HVAC companies that specialize in steam boilers because there are not a lot of the steam boilers used for residential and light commercial applications. People have either converted their old boiler steam systems over to hot water or have gone with forced air systems. The concept is simple but the mechanics of it can be frustratingly complex when a problem occurs unless you have the experience and knowledge that comes with working on the residential or light commercial steam boilers. Before we dive into some of the problems that arise with steam boilers, we’ll cover safety first. After all, HVAC safety is the most important aspect to any home heating system.
Here are some videos to help you make the best of installing a new standby generator for your home. It is very important to follow all generator manufacturers instructions, local and national codes, and general safety regulations when installing your own generator. The best advice High Performance HVAC can offer you is to always hire a professional to install the generator or at the very least hire a professional to check the job once it is completed and before the final inspection by the local municipality. There are two specific codes that must be followed in the installation of a natural gas/propane powered generator: The National Electric Code and The Fuel Gas Code and you will want to follow those codes to the letter for a proper installation. If there are any questions or doubt consult your local generator installation professional or call the manufacturer. Finally, before we get to the videos, be aware that the location of the generator installation is important. You do not want exhaust fumes from the generator building up inside the structure so properly locate the generator away from any openings including windows and doors to prevent carbon monoxide poisoning.
This picture shows a furnace flue with condensation problems. Flue condensation problems are caused by hot gases cooling too quickly in the flue. As the hot gases cool moisture in the gases condense and start dripping back down the flue. Flue condensation problems can be solved by making sure the gases are hot enough to be vented into the atmosphere before the moisture condenses in the gases. It could be a problem that requires a slight adjustment at the burner. It is a good idea, when you observe a furnace flue condensation problem where the condensation is dripping back down the pipe, to call a professional for to analyze the combustion process and make the precise adjustments necessary to prevent this problem. Condensation dripping back down the flue causes flue to prematurely corrode and rust. Flue condensation problems, if left alone, can cause the flue to rot and vent hot gases in an area where it could be very dangerous to the occupants of the building. There is carbon monoxide present in these gases and carbon monoxide is very dangerous.
Flue condensation problems have been observed on all kinds of furnaces including gas and oil furnaces. If you have this problem or see it on your furnace heating system please consult a professional.
