If your furnace starts making a loud sound like a clanking or squealing or, worse, suddenly stops working, you need one of our experts as soon as possible.

Many homeowners make the mistake of ignoring an unusual sound or smell coming from their furnaces. When something goes awry with your heating system, you should contact our team of professionals immediately.

You can expect our professionals to do whatever it takes to restore your heat regardless of the hour.

Is It Time for a New Furnace?

There are times when a repair is not enough to revive your furnace. Sometimes a replacement is the only answer.

There are also times when you know your furnace needs replacing soon, as most furnaces only last for 15 to 20 years with proper maintenance. When furnaces get older, they tend to lose their efficiency and cost you more money in energy even if they are running well. When you reach this scenario, you should act proactively and make plans to replace your furnace, which is always optimum.

In either case, our furnace professionals will calculate with precision the best sized and type of furnace to meet your home’s comfort needs. We will work with you to install the most appropriate HVAC system for your lifestyle and budget.

All newer furnaces have a higher energy efficiency, which translates to savings for you. With a higher energy efficiency, your new furnace will use less energy, thereby saving you in energy costs. Our experts only work with top-quality systems and materials, so you rely on the furnace you purchase will be a perfect fit for you and your Clinton Township home.

How Much Money Can a New Furnace Save You?

Our AFUE energy savings calculator can help determine how much you could save on your utility bills. Simply enter your current unit's AFUE value and compare it to a newer, more efficient unit. You can even customize it to better match your home's system for a more accurate calculation.

Maintenance Is the Key

We say regular professional maintenance for your HVAC system is the key, because we know its benefits. When you neglect proper maintenance on your furnace, it can’t run as efficiently as it should and could cause your energy bills to increase. Without maintenance, you could shorten your furnace’s lifespan as well as increase the chances of unexpected expensive repairs.

When you have professional maintenance completed on your furnace, you can expect better performance and longer life. That is why we recommend annual maintenance, usually in the fall before you begin to use your furnace for the season. Our knowledgeable and experienced professionals will prep your furnace for the cold weather by thoroughly inspecting and cleaning your system.

We stand firmly behind our company philosophy—“Experience the Service You Deserve!”—in every way, because at Great Dane we believe you should have the best service. As part of that service, we offer our Customer Care Program.

This program addresses your HVAC maintenance, providing you with various levels to help you find the best fit for your needs and budget. In addition to fulfilling your HVAC maintenance needs, there are numerous other benefits for you accompanying each level. We would be happy discuss our program with you, so call and speak with one of our friendly team members today.

“Richard was on time. He was very professional and friendly. He showed me beforeand after pictures of the pump that needed to be cleaned. He explained how to care for it in the future. I have always had great service from Great Dane!” – Judy A.

“I had a great experience with Great Dane. I had a leak from my exhaust pipe from my furnace that I was concerned about. The appointment setting was very easy when I called in – they were able to schedule me for the next day and the communication before arrival was super helpful! Nick was assigned to my house and he was awesome!!! Knew exactly what he was doing – ran back to the shop to grab parts – came back and had everything done in 15 minutes. He was very knowledgeable – answered all my questions and was very friendly! Highly recommend Great Dane and Nick – would definitely use them again should the need arise!”

– Caitlyn S.

“I called on Monday (1/30/23) morning for service and the technician came out the same day to check an issue that has some urgency. Mason Logie was able to figure out what the problem was. He kept me informed of what would be the projected solution including time frame and cost. He was professional and knowledgeable. I would highly recommend your company.”

– Riza L.

“Clayton was out for the yearly furnace maintenance checkup. After a cleaning of a part, the furnace is running nice and smooth.
Thank you, Clayton and Great Dane, for all your help.”

– Mary K.

“I almost never leave reviews…however I was so impressed with the level of service that Great Dane was able to give us I ifelt I had to! During the initial repair request, Dominic did a great job of educating us as to what was wrong, what could be done, and other possible resolutions. In the end we decided with the age of our unit, the best route was a full replacement. George came out to give us a quote and wlked us through what would be best for the size of our home and why, and once we decided on a unit, My wife and I were shocked when they told us they could install the following day! The gentleman that installed (Drew and Brian?) took great care in cleaning up before and after the installation, and helped us set up all the new features on the new thermostat and walk us through annual maintenance suggestions. Overall it was a phenomenal experience. 5 paws up!”

– Matthew S.

I would greatly recommend both Great Dane and Ryan Miller to everyone.

Thank you,
Bob Schimeck”

– Robert S.

“Same day of the installation of my air conditioner. Furnace kept running on heat. Called customer service and the installers returned to check out the problem. Eventually it came down to having a serviceman to come out and evaluate the problem. Chris was very professional, polite and on point for diagnosing the problem. He arrived quickly and upon consent ordered the repair part. It arrived 4 days later and Chris came back to do the repair. Everything works great. The customer service rep, Amy, was great. She kept me in the loop on the arrival of the repair part and followed up in letting me know Chris was on his way. I highly recommend this company. If I could give 10 stars I would. Using this company you will not be disappointed.”

– Steve S.
