The Ultimate Fall HVAC Tune-Up Checklist for Rochester Homeowners

Fall in Rochester hits different. One minute it’s sunny and crisp, the next it’s wind, rain, or even snow. That kind of wild weather swing makes one thing super clear: your HVAC system needs to be ready.

At K&S Heating, Air Conditioning, Plumbing & Electrical, we know just how fast a cozy fall evening can turn into a frigid night. That’s why a fall HVAC tune-up isn’t just “nice to have”, it’s essential.

Here’s your ultimate fall checklist to make sure your system doesn’t let you down when the cold really kicks in.

✅ 1. Change Your Air Filter

Simple? Yes. Easy to forget? Also yes.

Your HVAC filter keeps dust, dirt, and allergens out of your air and out of your system. A clogged filter makes your furnace work way harder than it should. That means higher bills and more wear and tear.

Quick tip: Change your filter every 1-3 months. If you have pets, do it more often.

✅ 2. Test Your Thermostat

Before the cold sets in for good, turn your thermostat to heat mode and bump it up a few degrees. Listen. Feel. Does warm air start blowing within a few minutes?

If not, you’ve got a problem that won’t fix itself.

Bonus move: If your thermostat is old-school, now’s a great time to upgrade to a programmable or smart thermostat. Better comfort, lower bills.

✅ 3. Clear the Vents and Registers

Walk around your home. Make sure all vents and registers are open and not blocked by furniture, rugs, or curtains. Closed vents don’t save energy; they throw off your system’s balance and can even cause damage.

Warm air needs room to move. Let it flow.

✅ 4. Check the Pilot Light or Ignition System

If you have a gas furnace, the pilot light should be a steady blue. Yellow or flickering? That could mean incomplete combustion, a safety risk, and a sign of a deeper issue.

Not sure what to look for? That’s what we’re here for. A trained tech from K&S can inspect your ignition system and make sure everything’s running clean and safe.

✅ 5. Clean Around the Furnace

Let’s be real, basements and utility rooms aren’t always the tidiest places. But your furnace needs a little breathing room.

Clear away boxes, dust, pet hair, and anything flammable. Leave at least 3 feet of space around the unit. It’s a safety thing. And it helps your system stay efficient.

✅ 6. Listen for Strange Noises

Rattling. Banging. Screeching. If your furnace sounds more like a haunted house than a heat source, something’s wrong.

Those weird sounds are your system crying out for help. Don’t wait until it breaks down completely.

✅ 7. Inspect Carbon Monoxide Detectors

This one’s serious. Carbon monoxide is odorless, invisible, and dangerous. Make sure you have detectors installed near every sleeping area and on each floor of your home.

Check the batteries. Test the alarms. Don’t skip this step.

If you don’t have detectors, call us. We can help get them installed quickly.

✅ 8. Schedule a Professional Tune-Up

Yes, you can (and should) handle some HVAC tasks yourself. But a full system check? That’s best left to the pros.

When you schedule a fall tune-up with K&S, here’s what we check:

• Heat exchanger (to catch cracks or leaks)
• Burners and flame sensors
• Blower motor and belts
• Electrical connections
• Gas pressure
• Safety controls
• Thermostat calibration
• Overall system efficiency

Basically, we catch the little things before they become big problems.

Why a Fall Tune-Up Matters

Let’s break it down:

• Lower energy bills – A clean, tuned system runs smoother and uses less energy.
• Fewer breakdowns – Catch issues early and avoid emergency repairs later.
• Longer system life – Maintenance = more years out of your furnace.
• Better air quality – Especially important in homes with pets or allergies.
• Peace of mind – No surprises on the first freezing night.

Seems like a no-brainer, right?
