When a problem comes up with a newer furnace, there are a few things you can probably pin the issue on. Unfortunately, new furnaces often run into problems because they were not properly installed. Incorrect sizing or sloppy installation lead to long-term and short-term issues within the system, likely causing an early breakdown. However, most problems with a newer furnace have to do with a smaller issue, like a small wiring issue or even a dirty filter.
But older furnaces are a different story. Problems that come up with an older furnace are often the result of a long history of wear and tear on the system, and the issues can be complex. That’s why you should always contact qualified technicians when you need furnace repair!
The first place to look when a heating system is not working the way that it should is the thermostat. This is what most people do, anyway, but it may be a bit more confusing an endeavor than expected. Today’s programmable thermostats can have complex settings that may be difficult to understand. And you may be wondering how to tell whether your thermostat is actually at fault.
You may have been told before that your boiler is affected by boiler scale (or boiler deposits), but you’re not sure whether to take this issue seriously. Scaling in boilers is actually an incredibly common problem. High levels of minerals in the water, such as calcium and magnesium, get left behind in the boiler tank and tubes, which may lead to a reduction in heat along with a loud banging noise, in some instances.
