Yes, it is possible. An electrical fire can break out if the compressor has inadequate ventilation. When it overheats but doesn't have a proper thermal cutout, this can cause the motor to short-circuit and catch fire. This risk is exacerbated if flammable materials, like dust and fallen leaves, are clogging the unit. The compressor overheating won't start a fire by itself, but poor maintenance and installation can increase the risk once it hits its breaking point and short-circuits.

It’s technically possible in some areas to install your own fire suppression system, but it’s usually not a good idea. Your system must conform to the fire code in your area and will need to pass a rigorous inspection before being activated and deemed safe. Installing a fire suppression system is a complicated job, and making mistakes as a DIYer is likely. Those mistakes can cause you to fail your inspection, which means you’ll have to spend more time fixing the issues or money to have a certified plumber do the work for you. It’s best to hire a professional.

Smoke detectors come in two different options: hardwired or battery-operated. While hardwired units are attached directly to the home’s electrical system, a battery-operated smoke detector only needs a simple battery for operation and can be placed virtually anywhere in your home. Some homeowners may mistakenly think their battery-operated units are hardwired in because all their units are interconnected, but many battery-operated units can operate within a smoke alarm network in your home.

A hot fire alone will not remove significant creosote buildup and can be dangerous, as it risks causing a chimney fire. While the warmth from a fire can help loosen stuck tar, making treatments like creosote logs more effective, it is not a substitute for proper cleaning. For existing creosote, the safest and most effective method is to have your chimney professionally cleaned by a chimney sweep.
