By Hadley Energy Solutions Team•April 6, 2026• 10 min read
- Check and Replace Air Filters: This is something you can (and should!) do regularly yourself, but we'll always check it. A dirty filter makes your furnace work way too hard.
- Inspect the Blower Motor and Fan: We'll make sure these parts are clean, spinning freely, and not making any funny noises.
- Clean and Adjust Burners: Dirty burners can cause inefficient heating and even safety hazards. We'll make sure they're clear and burning correctly.
- Examine the Heat Exchanger: This is a super important (and potentially dangerous if cracked) part. We look for any cracks or signs of wear that could lead to carbon monoxide leaks. This is why a professional HVAC contractor Louisville KY is so important!
- Check Ignition System or Pilot Light: We'll make sure your furnace is starting up reliably and safely.
- Inspect Gas Line and Connections: We're looking for any leaks or loose connections that could be dangerous.
- Test Safety Controls: Your furnace has several safety features built-in. We'll make sure they're all working correctly to protect your home and family.
- Measure Temperature Rise: This helps us know if your furnace is heating properly and efficiently.
- Check Thermostat Operation: We'll make sure your thermostat is communicating correctly with your furnace.
- Lubricate Moving Parts: This reduces friction and wear, helping your furnace run smoothly and quietly.
- Clear Condensate Drain: For high-efficiency furnaces, this drain can get clogged, leading to water damage or system shutdowns.
- Visual Inspection of Venting System: Ensuring that exhaust gases are safely leaving your home.
- Change Your Air Filter Regularly: This is huge! Check it monthly, and change it every 1-3 months depending on your home (pets, allergies, etc.). A clean filter is a happy furnace.
- Keep the Area Around Your Furnace Clear: Don't store boxes, clothes, or anything combustible near your furnace. It needs room to breathe!
- Listen and Look: Pay attention to any new or strange noises, smells, or if your furnace isn't heating like it used to. Don't ignore these signs!

Frequently Asked Questions
How often should I get gas furnace maintenance?
We recommend having your gas furnace professionally maintained once a year, ideally in the fall before you start using it regularly. This ensures it's safe and ready for the cold weather.
What happens if I skip furnace maintenance?
Skipping maintenance can lead to reduced efficiency (higher energy bills), increased risk of breakdowns, potential safety hazards like carbon monoxide leaks, and a shorter lifespan for your furnace. It's usually more expensive to repair than to maintain!
Can I do gas furnace maintenance myself?
While you can and should regularly change your air filter and keep the area around your furnace clear, a professional HVAC contractor should perform annual maintenance. They have the tools and expertise to safely inspect critical components like the heat exchanger, gas lines, and safety controls that homeowners shouldn't handle.
How long does a typical furnace maintenance appointment take?
A thorough gas furnace maintenance appointment usually takes about 60 to 90 minutes. This allows our technicians to perform all necessary checks and adjustments carefully.
What are the signs my furnace needs professional attention?
Look out for unusual noises (grinding, banging, squealing), strange smells (especially a rotten egg smell, which indicates a gas leak – evacuate immediately and call the gas company!), rooms not heating evenly, a yellow pilot light instead of blue, or if your furnace is cycling on and off too frequently. If you notice any of these, call us right away!
