![]() Can be noisy when air is blowing & possibly there can be pinging sounds in the ductwork from thermal expansion.Air quality can be made worse if filters aren’t changed regularly, dust & allergens can be blown around.Ductwork must be tightly sealed as leaks in ductwork can contribute to heat loss.This also makes it less efficient because you have to heat the whole house, whereas with mini splits & hydronic you can heat rooms individually. Although you can adjust the vents in each room the system isn’t capable of having thermostats in each room. Central systems (running off a single furnace) have one thermostat only.Warmth isn’t very evenly distributed, there can be hot & cold spots and floors tend to remain cold, especially tile. ![]() The most costly to run, not as efficient as hydronic or mini split, though modern systems are reasonably efficient.Can include a humidifier in the system to control humidity.Can include a filtration system to improve air quality.The least costly to install, especially for a system with both heat & ac.Can combine heating & air conditioning in the same system.If the system is combined with air conditioning it also requires a large outdoor unit called a condenser. Furnaces can be powered by gas, oil, electric or solar. Forced Air Heatingįorced air heating systems heat air with a furnace & an air handler distributes the air through ductwork & out air vents. ![]() While forced air is by far the most common, mini splits & hydronic heating are more recent innovations that offer increased efficiency. ![]() Some are stand alone heating systems while some combine heating with air conditioning. Modern heating systems come in many options & sizes & are powered by various energy sources, namely oil, gas, electric & solar. We say modern as we haven’t included the good old wood burning stove from days of yore. Here we’ve compared the three main types of modern heating systems, forced air heating, ductless mini splits & hydronic heating. ![]()
