Maximize Performance & Savings
The Benefits of Regular Heating Tune-Ups
Investing in regular maintenance is an investment in your home’s comfort and your budget. A well-maintained heating system operates more efficiently, consuming less energy to produce the same amount of warmth. This translates directly into lower monthly energy bills, often saving you a significant amount over the course of a single winter season.
Beyond the cost savings, routine service extends the lifespan of your equipment. Just like a car, your furnace or boiler needs regular care to continue running smoothly for years to come. By catching wear and tear early and ensuring all components are clean and calibrated, you can avoid premature system replacement and enjoy reliable warmth for years.

Don't Wait for a Breakdown
Signs Your Heating System Needs Repair
Ignoring the early warning signs of a heating problem can lead to more extensive and costly damage. Contact a professional if you notice any unusual symptoms, such as loud banging, grinding, or squealing noises coming from your furnace. These often indicate a mechanical issue that needs immediate attention.
Other red flags include a yellow or flickering pilot light, which can signal a dangerous carbon monoxide issue, or rooms that are heating unevenly. If your system is cycling on and off more frequently than usual or your energy bills have spiked unexpectedly, it’s a clear sign that your unit is struggling. A quick call to AA Service Co. can get an expert to your door to diagnose and resolve the problem safely.

Smart Savings, Better Performance
Improve Energy Efficiency and Lower Your Bills
An inefficient heating system is a constant drain on your wallet. As components wear down or become dirty, your furnace or boiler has to work harder and run longer to heat your home, leading to a noticeable spike in your gas and electric bills. Our professional maintenance and timely repairs are designed to combat this inefficiency and restore your system’s performance.
During a tune-up, our technicians clean and calibrate essential components, ensuring they operate exactly as the manufacturer intended. This simple act can significantly reduce your system’s energy consumption. By addressing repair needs promptly—like fixing a faulty thermostat or a worn-out part—we prevent your system from running in a stressed, inefficient state that wastes energy.
Investing in the health of your heating system is a direct investment in your home’s financial health. The energy savings from a well-maintained unit can add up quickly, often offsetting the cost of the service itself. Let us help you keep more money in your pocket while enjoying a warmer, more comfortable home in Libertyville or Lake Bluff.

We’ve compiled answers to some of the common questions we receive about heating maintenance and repair. If you don’t see your question here, please don’t hesitate to give us a call!
How often should I have my heating system maintained?
We strongly recommend annual maintenance for your furnace or boiler, ideally in the fall before the heating season begins. This ensures your system is clean, safe, and operating at peak efficiency for the winter.
What are the signs that I need a furnace repair?
Common signs include strange noises (banging, squealing), a pilot light that is yellow instead of blue, rooms heating unevenly, the system cycling on and off too frequently, or a sudden increase in your energy bills.
Can I prevent the need for heating repairs?
Yes! The number one way to prevent unexpected and costly repairs is by investing in annual professional maintenance. Regular tune-ups catch small problems before they escalate into major breakdowns.
What happens during a heating maintenance visit?
Our technician will perform a comprehensive inspection, cleaning, and tune-up. This includes checking electrical connections, cleaning burners, inspecting the heat exchanger for safety, testing system controls, and lubricating moving parts.
My furnace isn't producing any heat. What should I do first?
First, check that your thermostat is set to ‘heat’ and the temperature is set correctly. Second, check your home’s circuit breaker to ensure the furnace hasn’t tripped it. If these simple checks don’t solve the problem, call us for professional repair.
