Furnace Replacement

Sometimes a repair is not sufficient to fix your furnace. Sometimes a new furnace is the most cost-effective and energy-efficient way to go. We will always be honest with you about a possible furnace replacement. We value our time and your money––we don’t want to perform repairs or service on an appliance that is in need of replacement.

If you do need a furnace replacement, we know how overwhelming it can be. Here are some of the frequently asked questions about furnaces that we get from some of our Tuscon, AZ residents:

What Are The Different Types Of Furnaces?

Single Stage: A single-stage furnace has only one stage of operation. It can either be turned on or turned off.

Two Stage: A two-stage furnace has two settings––full and half speed. This is a more efficient way to heat and provides for better comfort, because it can move the air at a slower pace.

Variable Stage or Modulating: A variable-stage or modulating furnace modulates the speed and heat output based on the temperature outside and the desired comfort level. This furnace only works as much as you need it, making this type the most energy-efficient type of furnace.

What Is AFUE?

AFUE, or Annualized Fuel Utilization Efficiency, is a measure of furnace-heating efficiency. The higher the AFUE, the more efficient the furnace.

What Size Furnace Do I Need?

We can calculate the correct size furnace for your home. The number of BTUs, or British Thermal Units, needed to heat your home is dependent on a number of variables. Contrary to what you might think, a bigger furnace may not necessarily mean more heating power for your home. Call us at ACS Air Conditioning Services, and we can set up an appointment to calculate the furnace size you might need.

This company has *exceeded our expectations on every level

This company has *exceeded our expectations on every level. We were in desperate need as our Trane heater was failing miserably during an extreme period of hard freeze. I would like to first list the amazing bullet points for this company, before I acknowledge individuals. ACS provided us with service that was: Timely Informed Conscientious Thorough Clean Responsible Well rendered Knowledgeable *Ryan Foreman, (who was an installer and is now in sales), was sent out immediately to assess our circumstances. He was thorough in his assessment, very considerate of our circumstances, and extremely professional and pleasant. We had a bid by that afternoon that was intelligently rendered and easily understood. We were awaiting other bids but realized quickly that ACS was the company we trusted to do this installation for us ( based upon the service provided so far, and also by reading reviews online. Very impressive.) As we were in desperate need of a new unit ,*Erica ( in office) arranged for us to have : *Dustin Hardin arrive very early the next working day as our installer. He is third generation Hvac and very competent, mature, focused, and pleasant. And incredibly professional. *Very impressive!!! *Dan Walters was the individual who measured for our new unit the afternoon prior, and he was the second half of the team on installation day. Friendly, kind, hard working, and understanding of our circumstances, he did his best to assure us that we were in good hands! This team takes great pride in their work, and it is obvious from start to finish. They even kept an amazingly clean work space which is, frankly, rather rare nowadays. We consider ourselves blessed to have ACS help us through this trying time. We will tell everyone, as we already have, about the quality of work and level of professionalism from this entire company. A big shout out to ACS and the team of Ryan F., Dustin H., and Dan W. for making our home ever so much better than it has been in years. Sun S

I purchased a Daikin system

I was searching for a new AC/ gas heater unit and my friend recommended ACS. He said he had an excellent experience and received a competitive price. I included ACS in the bid process and they were very competitive for my system as well. The instillation was very professional and their attention to detail sort of blew me away. I purchased a Daikin system and I have been very satisfied. My house has two complete systems and ACS just finished the install of my second system (6 months later), which is proof that I an satisfied. M. Henry, Tucson Dec. 2017
