Millions of households rely on furnaces to stay warm. Adequate indoor heating can even determine whether a property is even habitable! That’s how critical these heating systems are to a household’s well-being. But, while air conditioners keep residents of hot regions comfortable, furnaces do a bit more. They keep people in cold climates from freezing in their beds! If your home falls under the latter and you are in the market for furnaces, read on for Done Plumbing & Heating’s simple guide to furnaces.

How It Works

The heat creation process is simple enough. To produce heat, an oil/natural gas burner switches on whenever the thermostat detects a drop in temperature. The furnace then transmits hot air at a rate of 700 ft. per minute. Of course, this assumes that the installer used the typical galvanized 30-gauge sheet steel to make the system’s ducts. You think exposing cold air to flame may appear too easy a task, and you’d be right. The challenge for our technicians is creating duct systems that bring that air to the rooms where it’s needed.

There is, of course, the matter of budget and time when it comes to larger homes and specific customer demands. Thankfully, ductwork is hassle-free with Done Plumbing & Heating all the same. In addition, we know our way around the inner workings of a building. This superior performance is given our extensive experience conducting heating and plumbing repairs in Denver.

What You Need

The critical metric is your furnace’s Annual Fuel Utilization Efficiency (AFUE). If your furnace’s AFUE is 50%, for instance, it means that your home receives just half the supposed amount of heating for all the fuel you spend, with the other half escaping outdoors. We can help you determine the AFUE of your furnace, whether it just needs repairs or replacement, and how the system can spend fuel better. High-efficiency furnaces (90%-100%) essentially pay for themselves through fuel savings alone.

Then there are the furnace types. If you want to maximize efficiency, the single-stage furnace may not be for you. Since it only has one operable setting, ON, users of single-stage furnaces can expect drastic peaks and valleys in their home’s indoor temperature. Meanwhile, two-stage furnaces have a HIGH and LOW setting, which makes for greater efficiency.

Finally, modulating furnaces are more like kitchen stoves. Their heat setting is adjustable to any point between the minimum and maximum levels. While this technology is newer, it’s proving to be an excellent application for customers who want the total amount of control of their heating system. Whichever furnace type you choose, you can trust us to deliver quality results from installation to repair and maintenance. We offer free estimates on new equipment, so if you need an assessment, contact Done Plumbing & Heating to learn more.

Let’s be honest: Nobody thinks about their plumbing and heating until there’s a problem.


What most people don’t realize is that most of those problems can be anticipated and often avoided with regular maintenance – usually at a far lower cost than a repair or replacement.

Reviews


“This past week I had the need for a plumber and I reviewed the telephone book and selected from the advertisements your company to attend to the matter. The company sent Austin Steinbach to attend to and review the problem. He is a very knowledgeable young man who communicates well and does his work in a very thorough and professional manner. I was very satisfied with his service. Mr. Steinbech is a credit to your company. Very often in communities someone asks whether they are aware of a plumber or other technician that can be recommended. In this regard, I am comfortable in recommending Mr. Steinbech and your company. Thank you for the service rendered.”

“Quick & competent work done to high satisfaction. Darrell Begay provided quick service and very professional work when he came to install a new toilet seat. We had not been able to do the work ourselves, so it was a relief to have Darrell and Done Plumbing get here so quickly to take care of the task. We appreciate all Done as done for us”

“Just a note to tell you of our recent positive experience with Kieth Croft. We found him to be friendly, knowledgeable, & efficient. When an issue arose with the clean-outs, Kieth quickly resolved it to our satisfaction & to the way he had previously described. From the estimate to the conclusion of the project we had confidence in Kieth. He is a good ambassador for your company.”

“Just a note of thanks for being the Best plumbing and heating company. I have used you often and have been impressed every time. I called for a drain cleaning and was told a technician could come the same day. He arrived an hour ealier than was quoted, was very professional and did a great job at a very reasonable price with my coupon that he honored. I would never use another company and would recommend you to anybody that needs help. The technician that did such a great job was Austin, but every technician you have sent has been the best. Thanks again for such a wonderful company”

~ Karla W Golden, CO

“It was very professional, prompt & the technician explained many things well. Very happy throughout the whole process – from the customer service rep who answered the phone this morning to the technician explaining building codes to me.
