Expert Furnace Maintenance in Southeast Minnesota

Why Furnace Maintenance Matters

It's easy to forget about your furnace when it's working properly, but neglecting routine maintenance can lead to inefficient operation, frequent repairs, and even safety hazards. Here's why regular furnace maintenance is essential:

• Improved Energy Efficiency – A clean and well-maintained furnace doesn't have to work as hard to heat your home, reducing energy waste and lowering your utility bills.
• Fewer Repairs – Catching minor issues early prevents them from turning into expensive breakdowns.
• Extended System Lifespan – Regular maintenance keeps your furnace in peak condition, maximizing its longevity and delaying the need for a costly replacement.
• Better Air Quality – A clean furnace and fresh filters reduce dust, allergens, and other pollutants in the air, helping you breathe easier.
• Enhanced Safety – Furnace issues like gas leaks or carbon monoxide leaks can be dangerous. Our maintenance checks ensure your system is safe and operating as it should.

Skipping furnace maintenance might seem harmless, but over time, dirt buildup, worn-out parts, and unnoticed issues can put unnecessary strain on your system, making it more prone to failures when you need it most.

Our Comprehensive Furnace Maintenance Services

At K&S, we don't just do a quick check and call it good. We provide a thorough, multi-point furnace tune-up that ensures every part of your system is working at its best.

1. Full System Inspection

Our technicians go through a detailed checklist, inspecting every component of your furnace. This includes checking the heat exchanger for cracks, inspecting the burners, testing the ignition system, examining electrical connections, and evaluating airflow to ensure optimal performance.

2. Cleaning & Component Adjustments

Over time, dust and debris accumulate in your furnace, reducing efficiency and leading to unnecessary wear and tear. We clean critical components such as the burners, blower motor, and flame sensor. We also lubricate moving parts to prevent friction-related damage, ensuring everything operates smoothly.

3. Air Filter Replacement

A dirty air filter restricts airflow, making your furnace work harder than necessary. This leads to higher energy bills and can cause overheating. We check and replace your filter as needed, helping your system maintain efficiency and improving indoor air quality.

4. Thermostat Calibration & System Testing

A thermostat that's not properly calibrated can cause inconsistent temperatures or force your furnace to run more than necessary. We test and adjust your thermostat to ensure accurate readings and efficiency. We also run a full heating cycle to verify that your system is responding properly to temperature adjustments.

5. Gas Line & Carbon Monoxide Safety Check

For gas furnaces, a gas leak is one of the biggest safety hazards. We carefully inspect gas lines and connections to detect any leaks. Additionally, we check the heat exchanger for cracks to prevent dangerous carbon monoxide exposure, ensuring your home stays safe.

6. Airflow & Ductwork Inspection

If airflow is restricted, some rooms in your home may feel colder than others, or your system may work harder than necessary. We inspect ductwork for obstructions, leaks, or inefficiencies that could be affecting your heating performance.

Signs Your Furnace Needs Maintenance

Even if your furnace is still running, subtle signs of trouble can indicate that it's time for a tune-up. If you notice any of the following, scheduling maintenance now can help you avoid bigger problems later:

• Uneven heating or cold spots in your home – Some rooms are warm while others feel chilly, signaling potential airflow issues or thermostat malfunctions.
• Strange noises such as banging, rattling, or squealing – Unusual sounds can indicate loose parts, motor issues, or belt problems that should be addressed before they worsen.
• Unusual odors when the furnace is running – Musty, burning, or gas-like smells could mean anything from dust buildup to a gas leak, requiring immediate attention.
• Increased energy bills without explanation – If your heating costs are creeping up despite no major changes in usage, your furnace may be running inefficiently due to dirty components or worn-out parts.
• Furnace frequently cycling on and off – Short cycling can be a sign of thermostat issues, airflow restrictions, or an overheating furnace that needs servicing.
• Weak or no airflow from vents – Poor airflow could be due to clogged filters, duct issues, or a failing blower motor.
• A yellow or flickering pilot light (instead of blue) – This could indicate improper combustion, which can lead to carbon monoxide risks and should be checked immediately.

Preventative Maintenance Plans

The best way to keep your furnace in top shape is to schedule regular tune-ups. To make this easier, K&S offers preventative maintenance plans that take the guesswork out of furnace care. With an annual plan, you'll receive:

• Annual furnace tune-ups to keep your system running efficiently.
• Priority service in case of breakdowns, so you don't have to wait in line.
• Discounts on repairs to help you save money if unexpected issues arise.

With a maintenance plan, you won't have to worry about remembering to schedule a tune-up—we'll remind you when it's time. Plus, regular maintenance helps prevent surprise breakdowns, giving you peace of mind.
