Furnace Tune Up in San Marcos, CA

Signs Your Furnace Might Be Due for a Tune-Up

Your furnace might not send you a calendar invite when it’s due for maintenance, but here are the signs it’s waving a little red flag:

• Increased Energy Bills: If you’ve noticed a spike in your energy bills, it could be a sign that your furnace is working harder than necessary due to wear and tear or inefficiencies. A professional tune-up can help improve its efficiency, extend its lifespan, and bring those bills back down, saving you money in the long run.
• Uneven Heating: Do certain rooms feel warmer or cooler than others? Problems like restricted airflow from dirty filters, obstructed vents, or failing internal parts might be behind the issue. A professional tune-up can pinpoint and resolve these concerns, helping your furnace deliver steady, reliable warmth—no matter how chilly it gets outside.
• Carbon Monoxide Leaks: Furnaces that are not properly maintained can develop cracks or leaks, potentially releasing carbon monoxide gas. This odorless and colorless gas is extremely dangerous, so regular tune-ups should always include checking for potential leaks and ensuring proper ventilation.
• Strange Noises: Your furnace may make some noise when turning on or off, but if you start hearing loud bangs, rattles, squeaks, or grinding sounds, it could indicate a more serious internal problem. A professional tune-up can identify and address these issues early, preventing further damage, costly repairs, or even potential safety hazards.

If you’re experiencing any of these, your furnace is practically begging for attention. Don’t ignore the signs—schedule your furnace tune-up in San Marcos, CA, with us, and we’ll take care of the rest.

Comparing Furnace Tune-Up Services: What Should Be Included?

Not all tune-ups are created equal. Here’s what a thorough furnace tune-up should include—and what you’ll get when you call Aelott Air Conditioning:

• Cleaning and Inspection of Key Components: Our technicians will clean and inspect your furnace’s key components, including burners, heat exchangers, blower motors, and electrical connections. This will improve efficiency, prevent future issues, and extend your furnace’s lifespan. A well-maintained system performs better and lasts longer.
• Filter Replacement: We'll replace your furnace's air filter to ensure optimal indoor air quality and maintain efficient airflow throughout your home. A clean filter not only prevents dust and allergens from circulating but also ensures your system doesn’t work harder than it needs to, improving energy efficiency.  
• Lubrication of Moving Parts: If not properly lubricated, moving parts in your system can wear out or become damaged over time. We’ll ensure all components are lubricated to reduce friction, prevent wear and tear, and avoid costly breakdowns, keeping your system running smoothly and reliably.  
• Thermostat Calibration: Accurate thermostat calibration is vital for maintaining a comfortable home temperature and preventing unnecessary energy use. We’ll verify that your thermostat is reading and responding correctly to your home’s temperature, ensuring consistent comfort and efficiency.
• Inspection of Electrical Components: Electrical components, like wires and connections, are critical for safe and efficient system operation. Our technicians will thoroughly inspect these elements, identifying and resolving any potential safety hazards or inefficiencies to ensure reliable and secure performance.  
• Checking Refrigerant Levels: Proper refrigerant levels are crucial for your air conditioning system to work effectively. Low refrigerant can lead to poor cooling or system damage, so we’ll check and adjust levels as needed to ensure optimal cooling performance and energy efficiency.  
• Inspecting Condenser Unit: The outdoor condenser unit plays a critical role in your AC system’s cooling process. We’ll inspect it for potential damage, debris, or obstructions that could reduce performance or cause strain on your system, ensuring it operates at peak efficiency.  
• Inspecting Ductwork: Ductwork distributes cool air throughout your home. We’ll inspect for leaks, damage, or blockages that could waste energy or reduce cooling efficiency. Addressing these issues ensures even cooling, lower energy bills, and a more comfortable indoor environment.

A proper tune-up is about more than ticking a few boxes—it’s about preventing breakdowns and maximizing comfort. Always ask what’s included before booking to make sure you’re getting full value.

Why Older Furnaces Need More Frequent Tune-Ups

Like fine wine—or your uncle’s vintage car—older furnaces need a little more TLC to stay in good shape. Internal components naturally wear down over time, seals loosen, and sediment buildup becomes more common. Left unchecked, these issues can cause unexpected breakdowns or safety risks.

Scheduling more frequent furnace tune-ups in San Marcos, CA, helps extend the life of your older unit, improve efficiency, and catch issues before they evolve into major repairs. If your furnace is more than 10–15 years old, consider moving from annual to biannual tune-ups.
