We won’t truly enjoy warmer spring weather for at least another month, and even then the temperature swings can be shaky. The short of it is you need to have your furnace working well through the spring. Now is not the time to ignore troubles with your furnace just because you might be able to “wait it out.”
There are several important reasons to always act fast on furnace repairs, but the top one is that a natural gas furnace (which is what you probably have in your home) may turn hazardous if repair needs are ignored. Gas furnaces aren’t an inherently dangerous type of heating system, but negligence raises the chance of safety hazards.
