What Does AFUE Mean?

While an air conditioner’s efficiency is measured by its SEER (Seasonal Energy Efficiency Ratio) rating, an electric or gas- or oil-fired furnace’s efficiency is measured by its AFUE, or average fuel utilization efficiency. This standard measurement is given in percentages, letting you know how much of your fuel is actually used to heat your Colorado home and how much fuel is wasted.

Air Filter Replacement in Greenwood Village, CO 80111

“Southwest Heating and Cooling is simply the best. You don’t have to be apart of the “Club” to get a discount on your service. I am so tired of plumbing, electrical and heating companies quoting me two prices….one for non members and the cost for members in their programs. I have been using Southwest Heating & Cooling for the past five years…I am very satisfied with their quality of work and I feel they are honest with their pricing. From my first phone call for service or repair they constantly keep me in touch and I love, as a senior, receiving an email with a picture of the technician who will be servicing my project. In the last five years, I have had Southwest replace an air conditioner, hot water heater, humidifier, and now an electronic air filter. I could not be more pleased and happier with their personnel and workmanship.”
