The evolution of furnaces has been significant over the years. Conventional furnaces exhausted combustion gases fast and hot so they would exit the chimney flue before cooling and condensing. The furnace heat exchanger would not as efficiently collect as much heat from the fuel combustion process as possible. Condensing furnaces have the ability to capture some heat even after the combustion exhaust gases have cooled and condensed. This is accomplished by utilizing two heat exchangers, one designed for primary heat exchange and one to handle condensed exhaust gases consisting of water and carbon dioxide. The exhaust gases are depleted of a portion of their heat until the condensate drips out of the heat exchanger and the flue gases exit from a plastic PVC pipe instead of a chimney.

Furnace Efficiency Ratings

The annual fuel utilization efficiency (AFUE) is a thermal efficiency measure of combustion equipment such as furnaces, boilers, and water heaters. AFUE measures the amount of fuel converted to heat in the space, in proportion to the amount of fuel entering the furnace. The higher the AFUE rating, the more efficient the furnace is

A1 did an excellent job on our furnace and ac replacement after our old unit failed. The new unit also seems to be keeping the temp better regulated and the filter already looks filthy indicating it is doing its job unlike the last setup. I really appreciate everyone that works here and what they do! Update: at my new house I had them assist in putting ducting in the basement as I work towards finishing it. They were prompt and courteous and the work was excellent as always.

Update 2/15/2022: I will continue to rave about this company! Super fast and friendly service! They ALWAYS find the problem and have been so kind and understanding every time! The Owners are wonderful and they do a fantastic job finding wonderful employees to represent their company! I still continue to ONLY use A-1 and recommend them any chance I can get. ............... A-1 has always been Fantastic to do business with. We got our central A/C system installed by them and they even came out to inspect it when things weren't working right. Turns out the issue was user error but they did such an amazing job of being patient with us to explain the issue, educating us on how to better care for our system, and even made sure the entire unit was updated and running smoothly before they left. They are fast in their responses and their 24 hour service is great highly recommend A-1. We won't use anyone else!

I have used this business twice now to repair and tune my furnace. Both experiences have been exceptional. Both of the guys who came at the two different appointments were extremely courteous, very professional, knowledgeable, and timely. For both appointments I have had they were able to come to my home based on what worked best with my schedule and were very flexible. They arrived when they said they were going to and fixed everything that needed to be fixed without taking an entire afternoon. They explained things in a way that made me feel like I understood what was being worked on without feeling like I was being talked down to. I will continue using this company for all of my air conditioning and furnace tuneup and needs in the future!
Aaron did such a super job for us and was so energetic and friendly. He quickly diagnosed the problem, fixed it and assured us that he would return if needed. I am sure he even saved us some money. He called ahead and arrived on time. Can't say enough about this young man and his work ethic.

Got the new furnace seamlessly scheduled for replacement and promptly installed by tech Hunter,new furnace is quieter, more efficient then the old one A-1 installed 29 years ago. Very proffesional service !
