When heating systems are working correctly, they are perfectly safe equipment to have in your home.
However, since furnaces burn fuel to generate heat, they can develop serious safety issues when they start to malfunction.
Fortunately, multiple devices are incorporated in various parts of your unit designed to detect when issues happen. These safety components include a limit switch, thermocouple, mercury flame sensor, air pressure switch, and carbon monoxide detectors. These safety features are included in modern-day heating systems to ensure the safety of your system and your home. The safest HVAC system for residential heating includes a standard AC and furnace split system. These systems are sometimes referred to as forced air systems. With this type of system, a blower fan draws in untreated air, heats it, and pushes it back through your ducts into your living space. In most cases, the furnace is natural gas powdered, while homes with ready access to natural gas may also have a propane-powered unit. Then there is the standard heat pump. These heat pumps provide both heating and cooling. A compressor circulates refrigerant throughout your system. Warm air is absorbed in your outdoor space, concentrated, and delivered into your indoor space. An indoor air handler with a blower pushes the air through your unit and circulates it into your living space. Another safest option is the geothermal heat pump system. This system is highly energy-efficient since it uses natural temperature from the earth. They are most popular for homeowners leaning towards green living practices.
