What Does AFUE Mean?

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.

Very friendly company and technicians knowledgeable and made it clear that they wanted to make sure that all of my concerns were taken care of before the technician left. Technician was quick. Did good quality work and provided an easy to understand analysis of what the issue was. What needed to be corrected and then perform those corrections. Within minutes of completing the repair, Meyer conditioning system was working like it was when it was brand new and it cooled my house down about 2,000 ft² 2 degrees when it was 85° outside from 74 to 72. The technician explain to me The most ideal way to keep our house cool in the summer time which is to open up your windows while the air outside is less than the temperature you're shooting for inside and once you reach that same temperature outside, close everything up, close your shades and keep sunlight from coming in. Keeping warm air from coming in.Would recommend them to anyone that needs heating and air conditioning work for their systems.

A professional named Andrew Heinz came out to look at my unit. After inspection, Andrew determined that the off brand split was installed incorrectly and wrong materials and tools to install. Most companies won't work on AC with no information. Discussed about a new proper system and waiting for estimates. Highly recommend Andrew if possible!

Mike C came out on a hot weekend (after hours) to help troubleshoot a broke A/C unit. He was incredibly professional and worked to make sure I understood the problem and offered a variety of solutions based on budget requirements. He worked to make sure I was getting the best deal and system for my house and budget. I did have to go with an A/C replacement. Southwest Heating and Cooling was able to secure equipment and book the install within the week. I highly recommend this company for heating and cooling needs.

Angel, who has serviced our HVAC unit before, was very thorough and explained everything he was doing so I could do much of it without calling the next time. He was accompanied by another gentleman whose name I can't recall. He was also very professional and helpful. I highly recommended SW Heating & Cooling.

June 2022We had a new air conditioner and furnace installed. We had an immediate need. Mike, owner, met with us personally to review options from last year. Tony and Ray were terrific installers. On time, professional, left our place spotless. They went over all my questions. The office staff took care of all product registrations and rebate offers. This was a great outcome for us. Great job.July 2021Great choice we made having Southwest Heating and Cooling service our unit. On time, spent time explaining to us what our system status is, etc.... Jake was great to work with. He left us with options on a new system, explained our options, reviewed their annual maintenance plan with us and overall treated us like family. We will definitely be recommending and using their services again.
