Most people don’t think about their furnace until something goes wrong. That’s completely understandable, but it’s also the kind of thinking that leads to unexpected breakdowns and costly repairs. At Degree Above Heating & Air, we believe a little attention before the heating season can save you a lot of headaches during it. We’re a local, family-owned team that takes furnace maintenance seriously, because we know how much you’re counting on your system when the temperatures in Raleigh finally drop.

Jesse came this morning for the annual maintenance check at my husband’s and my home. He was very knowledgeable and professional. We are very pleased with their service and do recommend them.
Lawrence Rollman
He got to me same day (weekend), the circuit board he got from the supplier was bad but he was able to use one off the truck to get it working. Took a lot of extra time of his than expected but he got the heat on. Would definitely recommend. Thank you

Why Regular Furnace Maintenance Matters

Your furnace works hard, especially after sitting dormant through a long, humid Raleigh summer. Regular maintenance keeps it running safely, efficiently, and reliably when you need it most. Here’s what staying on top of it does for you:

  • It helps catch small problems before they turn into expensive repairs or full system failures.
  • It keeps your system running efficiently, which means lower energy bills throughout the heating season.
  • It extends the overall life of your equipment so you get the most out of your investment.
  • It helps maintain healthy indoor air quality by keeping components clean and airflow unrestricted.
  • It gives you peace of mind knowing your system has been inspected by someone who knows what to look for.

What Happens When You Skip Furnace Maintenance

Skipping your annual tune-up might not seem like a big deal, but over time the effects add up. Dust and debris build up on components that need to stay clean to function properly. Small issues like worn parts or a slightly cracked heat exchanger go unnoticed until they cause a bigger problem. Your system has to work harder to produce the same amount of heat, which drives up your energy costs and puts more strain on the equipment. In some cases, neglected furnaces can develop safety concerns like carbon monoxide issues that could have been caught and corrected during a routine visit. The cost of skipping maintenance almost always exceeds the cost of doing it.

What's Included in Our Furnace Maintenance Service

When Degree Above Heating & Air comes out for a furnace tune-up, we do a thorough job. We’re not just checking a few boxes and moving on. Our maintenance service includes inspecting and cleaning the burners, checking the heat exchanger for cracks or damage, testing ignition and safety controls, inspecting the blower motor and belt, checking and tightening electrical connections, testing the thermostat for accurate operation, inspecting the flue and venting system, and replacing the air filter if needed. We look at the whole system so you get a complete picture of where things stand.

What We Commonly Discover During Furnace Tune-Ups

Routine maintenance visits often turn up things homeowners had no idea were there. Some of the most common findings include:

  • Dirty or clogged filters that have been restricting airflow and causing the system to overheat.
  • Buildup on burners that affects how efficiently the furnace is combusting fuel.
  • Loose electrical connections that could cause intermittent issues or become a safety concern over time.
  • Early signs of wear on the blower motor or other moving parts that are easy to address now but could cause a breakdown later.
  • Minor heat exchanger issues that are far less costly to handle before they become a serious problem.

How often should I schedule furnace maintenance?

Once a year is the general recommendation, ideally in the fall before you start relying on your heating system regularly.

Yes. A clean, well-tuned furnace runs more efficiently, which typically shows up as savings on your monthly energy costs.

We’ll walk you through exactly what we found and give you honest options so you can decide how you’d like to move forward.

Absolutely. Regular maintenance helps newer systems last longer and can also be a requirement to keep manufacturer warranties valid.

Most maintenance visits take about an hour to an hour and a half depending on the condition of the system.
