Home / Furnace Maintenance
At Harker Heating and Cooling Inc., we understand the importance of keeping your furnace operating at its best. Annual maintenance by our certified HVAC technicians optimizes your furnace’s performance to ensure you get the most out of your heating system.
Our furnace maintenance experts check for issues that you can’t detect on your own.
A well-maintained furnace will last over 15-20 years, while neglect can lead to premature breakdowns. Without preventative maintenance, dirt, corrosion, and buildup in the heat exchanger or ducts can reduce airflow and performance. Neglecting service tasks like filter changes or cleaning can force your furnace to overwork, increasing energy consumption. Complete neglect will likely lead to a full breakdown, requiring an emergency furnace repair that can be inconvenient and costly.
Protect against unexpected repair costs and cold winter days. Schedule furnace maintenance with our skilled team of furnace technicians today.

Your furnace is one of the hardest-working systems in your home. During our long Wisconsin winters, it runs nearly continuously to keep your family warm. Without regular care, even the most reliable furnace will eventually develop problems—and they rarely happen at convenient times.
We’ve seen countless situations where homeowners skip maintenance, only to have their furnace break down in the middle of winter when they need it most. That’s not how we want your story to go. At Harker Heating & Cooling, we believe that reliable furnace maintenance in Madison, WI is an investment, not an expense. When we maintain your system properly, we’re protecting your comfort, your safety, and your wallet.
A well-maintained furnace operates more efficiently, which means lower energy bills. It also has fewer breakdowns, lasts longer, and keeps your manufacturer’s warranty intact. In fact, most furnace warranties require annual maintenance—skip it, and you could void your coverage when you need it most.
When we perform furnace maintenance at your Madison home, we don’t just show up and check a box. Our technicians conduct a thorough inspection and tune-up that covers everything critical to your system’s health.
This comprehensive approach means we catch issues early, before they cause breakdowns or safety concerns.
We recommend scheduling annual furnace maintenance in the fall, before heating season begins. This is the single best time to prepare your system for the demands of Wisconsin’s cold months.
Think of it like getting your car’s oil changed before a long road trip. You want everything in working order before you need it to perform at its best. Fall maintenance gives us a chance to identify and fix any issues while the weather is still mild and our schedule isn’t packed with emergency calls.
If your furnace is older (15+ years), has been neglected in previous years, or is experiencing any problems, we may recommend more frequent inspections. We’ll always be honest about what your specific system needs.
Here’s something many homeowners don’t realize: skipping maintenance doesn’t save money—it costs you. Here’s why:
A furnace that hasn't been tuned up has to work harder to heat your home. That dirty filter, the uncleaned flame sensor, the unlubricated blower—they all add up. We've seen properly maintained systems use 10-15% less energy than neglected ones. Over a heating season, that's real money in your pocket.
Furnace breakdowns in January are expensive. Not only do you pay more for emergency service calls, but the repair costs are often higher because the problem has had time to snowball. A small issue that costs $200 to fix in October can become a $1,200 repair in the middle of winter.
A furnace that receives regular maintenance typically lasts 15-20 years. One that's neglected might only make it 10-12 years. That's thousands of dollars lost on premature replacement.
Your furnace comes with a manufacturer's warranty, but it's only good if you maintain your system. Skip maintenance, and you lose that protection when you need it most.
The bottom line? Reliable furnace maintenance in Madison, WI isn’t optional—it’s essential maintenance that pays for itself.
We believe in preventing problems instead of just fixing them. That’s the philosophy behind preventive furnace maintenance, and it’s been serving our customers well for decades.
During a preventive maintenance visit, our technicians are looking for warning signs. A little corrosion on the heat exchanger. Slightly loose electrical connections. A blower wheel that’s working harder than it should. These small issues won’t break your furnace next week, but left alone, they’ll cause problems down the line.
By addressing them now, we prevent future breakdowns. You get peace of mind knowing your system is safe and reliable when winter arrives. And you avoid those expensive emergency repairs that leave you without heat when your family needs it most.

When you should replace your furnace filter depends on your filter’s thickness. For an average 1-2 inch filter, you should replace it every 1-3 months. Larger filters last longer, and can be replaced every 6 months.
On average, it takes anywhere from half a day to a full day for our HVAC experts to replace a furnace. However, the type of furnace, the electrical and gas lines in your home, and any ventilation requirements for your furnace can impact replacement time.
Yes, it’s best to get your furnace serviced every year to ensure your furnace is in working order. Preventative maintenance can improve your furnace’s efficiency, extend its lifespan, ensure safety, and prevent equipment failures down the line. Without maintenance, caught dust, debris, or unnoticed issues can cause future breakdowns and total system failure.
Schedule annual preventative maintenance with a Harker expert to keep your furnace in good condition.
Harker experts perform preventative maintenance on furnaces to prevent future performance issues. Maintenance includes an “annual checkup” where experts inspect each part of your furnace for issues, as well as a deep cleaning of all internal parts and lubrication of moving components. If our experts notice any issues, they will be able to diagnose the problem and suggest a repair.
You should schedule furnace maintenance annually. Any abnormal noises, unexplained heating cost increases, poor airflow, or visible rust and cracks are signs to schedule maintenance, even if your furnace was recently serviced.
