Having an efficient, working heating system is literally a matter of life and death in this frozen tundra we call Iowa.

Symptoms of a Failing Furance

If any of these red flags are waving in your home, give us a call. We’ll have one of our expert technicians get down to the root of the problem. If you’re in the market for a new furnace, thermostat, or heat pump, we will help fit your home with the proper equipment.

Your utility bills are abnormally high
Your furnace is blowing cool air
Your furnace seems much louder than it used to
You’re constantly adjusting the thermostat
Your furnace cycles on and off frequently
Your house is dry or dusty
Your furnace won’t kick on at all


Choosing a new furnace can be overwhelming, especially when you feel as though you’ve been pushed into the decision to replace by an unexpected failure. Even in the most well-planned furnace replacement scenario, there’s a lot to consider. We’re here to guide you through the process. Our experts will make sure that you’re armed with the information you need to choose the heating system best suited to you and your home.


A furnace is indeed the most common way to heat Iowa homes, but it’s certainly not the only method. Rest assured that our HVAC installers are just as skilled at geothermal heat pumps, mini splits, and even garage heater installation.



We service and repair furnaces of all makes and models. We know that your heat going out can be incredibly stressful, that’s why we take the pressure off of you. Give us a call when your furnace acts up, and our expert technicians will take it from there! We also recommend regular maintenance to extend the life and improve the efficiency of your furnace. If you want a convenient way to make sure your furnace is kept in good shape, consider our maintenance plan, which includes an annual inspection and a 10% discount on parts and labor!

Rest assured that we can handle whatever you’re using to stay warm: from heat pump maintenance to servicing a geothermal system to midnight boiler repair, we’ve seen it all. Need a furnace ignitor replacement, or just a routine checkup? We’ll handle it. Turn to us for your furnace tune-up or furnace inspection during the fall and winter months.


Whether it’s your annual fall check up or a middle-of-the-night emergency, CW Suter’s got you covered. We repair furnaces of all makes and models, whenever they break down. We’re ready to make emergency repairs to your heater or install a completely new gas furnace, no matter what time of day or night. Or weekend. Or holiday. Twenty four hours a day, three hundred sixty five days a year: Service that suits you.

Heating System Warranty, Rebates, & Registration


Have you ever tried to submit a warranty claim on a small appliance, only to find that you forgot to fill out and send in that little registration card? Or found out that you’re disqualified from receiving a rebate because you didn’t mail in the correct label? Have you ever made a purchase and then thrown up your hands in frustration because it seems like your paperwork has paperwork?


The good news is that CW Suter handles ALL the paperwork for you. Not only that, but we also make sure that you get all of the rebates that you qualify for and that your equipment is properly registered. Because your new equipment is properly registered, your investment is backed by the manufacturer warranty from the moment we have it installed. How awesome is that?


Investing in a new furnace shouldn’t be a stressful experience. We’re committed to taking care of our customers for the long haul. On most heating equipment, we offer a 10 year limited warranty on all components, including the compressor, and a 1 year labor warranty.

Getting Started

Regardless of your “why” – whether your furnace is acting up or you’re looking for ways to make your home more efficient and planet-friendly – the first step is to get in touch with one of our Suter Heroes. Schedule your free home comfort assessment online or by telephone – or even by clicking the chat button on the bottom of the page! Our specifically trained HVAC expert will come armed with your home’s structural info. They will then gather information such as the number of windows, doors, and people who reside in your home. Factors such as climate and the size of your home are also important. Using cutting-edge software, our expert will perform the load evaluation calculation which will tell them the number of BTUs (British Thermal Units) needed to heat and cool your home. From there, CW Suter Services will help fit your home with the appropriate unit.

Maintenance Plan

We also provide a Residential Maintenance Plan, for homeowners who are looking for a simple, affordable way to automate their system’s maintenance.

Financing Available 

No one should have to wait around with a broken HVAC system. That’s why we offer financing options so you can get your new equipment fast!
