If you have any questions, or for advice on selecting the best heating system for your home, you can always contact Kings Heating & Air Conditioning in Lynnwood, WA.


The latest gas furnaces are now equipped with an electronic igniter to light the gas, which then heats the home. In these newer furnaces a pilot-light system is not used as was the case with the older furnaces. Furnaces fitted with an electronic igniter cannot be lit manually.

The igniter lights several burners in a combustion chamber. The heat generated collects in a heat exchanger and is then transferred to the air, raising that air to the temperature set on the thermostat. The air is then delivered to the rest of the house through the ducts.


An alternative to natural gas is Liquefied Petroleum gas (LP gas or LPG). LPG is a flammable mixture of different gases and consists of either propane or butane which are both hydrocarbons. When liquefied LPG can be easily transported and stored.

The LPG heating systems work with radiant floor systems as well as convective fan-driven heaters, or a combination of both. LPG systems can be tailored to heat targeted rooms which helps increase the efficiency or it can be applied to an entire home area.

Most furnaces have done away with a pilot light, which is a flame that burns continuously, ready to ignite the burners when required. Furnaces are now fitted with intermittent, direct spark, or hot-surface ignition increasing efficiency.


Heat pumps have a compressor and two copper coils, one of which is indoors while the other is outside. The outside coil takes heat out of the air via a liquid refrigerant when heating is required. The indoor coil then releases the heat from the refrigerant, condensing it back to a liquid state.  To cool the indoors, the process is reversed.

You should look for efficient electric heating systems with HSPFs (heating season performance factor) in the range of 8 to 10 and SEERs (seasonal energy efficiency ratios) in the range of 12 to 18. 

4. OIL

Oil-burning furnaces are not as common in the Pacific Northwest, but they still heat a lot of older homes. Home heating-oil systems work by burning heating oil. The fuel is drawn from a storage tank by a pump. The fuel next goes through a fine spray nozzle where it mixes with air and is ignited. The heat from the combustion chamber is then used to warm up air or surrounding water/steam for use in the home. Heating oil is a mixture of hydrocarbons that are much heavier than alternatives such as natural gas or propane. It is transported by tanker trucks and stored in large above-ground tanks.

Choosing the right home heating system and sizing it properly requires the support of a trained professional. Do not leave it to any untrained person to do. You can rely on Kings Heating & Air Conditioning in Lynnwood, WA to provide top quality heating system replacements and upgrades that will stand the test of time.
