I have had these units for quite some time now and before that, I had gone through 3 other units thus I am familiar with most problems that affect our boilers and there is also a story attached to each issue. Boilers stop working for all sorts of simple reasons from a broken thermostat to a dirty filter. There are other times however that the issues are a bit more complex. Most times when the issue proves tricky to solve usually involves several parts within the furnace. When a customer calls in complaining of a dead electric furnace, the most common reason is usually a malfunctioned hot surface ignitor. These devices are readily available and can be installed by a heating technician. Blocked vents are one of the reasons I switched to a ductless heat pump, therefore, I don’t have to ensure the vents are clean and clear of any blockage. This issue could cause issues for the unit. Another issue that plagues most central heating units is a badly done heat pump install. I made sure to hire an experienced local contractor to install the zone control unit in the best ideal place to avoid future issues. One time my dual fuel system was not providing the usual quality heating and I realized that the air filter was clogged. An energy saving tip recommended using a HEPA filter which would trap even the smallest particle and it was changeable. When the gas fireplace will not turn on, it is smart to first check for leaks and rust, and if any turn off the fireplace and contact an expert to resolve the issue. I have grasped an important tip to perform a routine inspection on my unit in order to maintain the quality heating service it provides me.
