Some of the most efficient heating systems available are forced-air furnaces. They burn fuel to heat air and force it through ducts to keep your entire home at a comfortable temperature.

Virtually all modern furnace systems rely on one of two fuel sources. A gas furnace burns natural gas to produce heat, while an oil furnace relies on heating oil. For most consumers, choosing between natural gas and heating oil will depend on fuel availability and cost in a given area.

Gas furnaces generally reach higher fuel efficiency levels, but today’s heating technologies have improved to the point where excellent annual fuel utilization efficiency (AFUE) ratings can be achieved on both types of systems.

There are, of course, some factors that will affect the actual fuel efficiency of your furnace, such as the size of the home, layout, insulation and ductwork. Advanced Comfort Specialist’s technicians can inspect your home, evaluate these factors, and determine the actual energy efficiency of any system.

Once our customers weigh this information, together with the cost of fuel and installation, they are able to select the best equipment for their family’s comfort needs and their budgets.


A gas boiler is another alternative and may be the cleanest and most energy efficient way to heat your Lehigh County home or office. Boilers operate efficiently and typically last longer than other heating systems, offering excellent value.

Boilers, also known as hydronic heat systems, use hot water for heating. The heat is distributed through hot water pipes, using a pump to heat baseboard, cast iron radiators, or radiant flooring systems. A steam boiler distributes steam through a network of pipes to heat the radiators. Boilers can run on gas, oil or electricity.

You may be thinking that using a boiler system for heat and separate central air conditioning for cooling sounds more expensive than simply using the A/C ductwork for heat by adding a furnace. But hot water heating may be worth the additional cost.

Furnaces blow warm, dry air all around, often creating a drafty environment. This air circulation works well in the summer for cooling, but may not provide the most comfortable heat. Furnaces may also blow dust and allergens through your home. In comparison, the radiant or convection heat from a boiler is gentle, steady and consistent. And there’s no risk of spreading allergens or dust.

Advanced Comfort Specialists can help you weigh the pros and cons of the various heating options to help you decide on the best way to heat your home or office. We can also help you maintain your system’s peak efficiency. If your furnace or boiler is running less efficiently, making strange noises, frequently cycling on and off, or showing other signs of a potential problem, we would be happy to take a look at it.
