Gas is currently the most common heating fuel and most new central-heating systems use gas. How efficiently a furnace converts gas into heating energy is reflected in its annual fuel-utilization-efficiency (AFUE) rating, which is measured as a percentage. The higher the number, the more heat the furnace can wring from each therm of gas. Since efficient furnaces generate fewer emissions, environmental considerations might also influence your decision.

Heat pumps act like an air conditioner in the summer, removing the heat from the air and then recirculating the cooled air throughout your home. In the winter, though, they can transfer ambient heat from outside into your house, efficiently warming your home with minimal energy consumption. If you do decide on a heat pump in Seattle, WA, make sure that you schedule your installation, maintenance and repair services with a skilled, qualified technician.


When choosing a heating and cooling company, it's important that you find one that employs licensed, highly trained, background-checked, and drug-tested technicians. Considering this person will be in your home, it would be nice if the technician is also well-groomed, honest, polite, informative, and will give you options on how to improve your comfort.
The thermocouple is a copper rod that the pilot flame heats-up. When it gets hot enough, the thermocouple signals that there is enough heat to burn the gas fuel being released into the appliance—and so it allows the gas to be released to the burners. In some cases where the pilot light won’t stay lit, the thermocouple needs to be adjusted or replaced. This is generally a job for a professional.
Cleaning the debris that builds up on your filters will aid with the flow of air. When your air filter is clogged, your air handler must work harder to compensate for the blockage of air flow. In addition to driving up your utility bill, the reduced air flow through your heating and cooling system can cause your heat exchanger to overheat and shut off too quickly.
