Heating System Performance: The Basics of a Combustion Efficiency Test

A combustion efficiency test performed by a qualified HVAC service technician can detect gas furnace issues that a simple visual inspection might not reveal. Combustion efficiency relates to the percentage of various gasses present in the exhaust stream discharged by the furnace up the vent pipe. By testing exhaust gasses with a combustion analyzer, the technician can identify potential issues with furnace components that affect heating peformance and safety. A combustion analyzer measures levels of carbon dioxide and carbon monoxide, […]

How to Know if Your Furnace Efficiency is Right

Furnace efficiency begins with the AFUE rating determined at the factory. Short for Annual Fuel Utilization Efficiency, AFUE is a percentage that expresses the amount of fuel consumed that actually produces heat versus the percentage lost during combustion and venting.   Mandated by federal regulations, today the AFUE standard efficiency rating for furnaces is 80%. More expensive high-efficiency furnaces that recover lost heat, however, come with an AFUE as high as 95%.   AFUE is simply the starting point for […]

Optimize Furnace Efficiency with a Simple Filter Change

In order to keep dirt, mold spores and other particles in your air from getting into your heating system and causing damage, you’ll have to install an effective furnace filter. Regularly replacing your furnace filter is the easiest way to maximize furnace efficiency, while also improving the quality of your indoor air. In order to optimize furnace efficiency and get the most benefit from your furnace filter, you’ll have to: Change it Regularly As your filter traps more dirt, it can become clogged, restricting airflow. […]

Is Now The Time To Upgrade To A High-Efficiency Furnace? Do The Math

Most everyone is trying to save money these days. Sometimes people try to save money by delaying purchases or by going with the cheapest options. At Powers Heating and Air, we are definitely in favor of saving money. To do so, though, you need to consider the long-term costs involved. Sometimes going with the cheapest option or continuing with the status quo does not save you money at all. Take furnaces, for example. The cost of heating fuel has gone […]
