Hey folks, Jake Lawson here. If you’ve dropped your hard-earned cash on a high-efficiency R-32 AC and gas furnace combo, you want it to last—ideally 15, maybe even 20 years.

But here’s the truth: most systems don’t die because of bad parts. They die because no one gave them the regular TLC they need.

Good news? You don’t need to be a tech to stay on top of it. Below is my Jake-approved annual HVAC maintenance checklist—simple enough to do yourself (or hand off to a pro), but packed with everything that’ll keep your system running at peak efficiency.


🗓️ Spring Maintenance (Before Cooling Season)

1. Change the Air Filter

  • ✅ Frequency: Every 1–3 months

  • Clogged filters make your AC work harder. Check it monthly and replace when it looks dirty.

2. Clear the Outdoor Unit

  • Remove leaves, twigs, or grass clippings from around your R-32 condenser.

  • Make sure there's 2 feet of clearance all around for airflow.

3. Inspect the Coil Fins

  • Gently straighten bent fins with a fin comb. Damaged coils lower efficiency.

4. Clean the Evaporator Coil

  • If you can access it, lightly vacuum dust from the surface.

  • For more buildup, have a pro clean it using coil cleaner.

5. Check Refrigerant Lines for Insulation

  • Make sure the lines leading to the AC unit are fully insulated. Missing foam? Replace it.

6. Test the Thermostat

  • Set it to cooling mode and confirm your AC cycles on and off properly.

  • Upgrade to a smart thermostat for extra savings and better control.


🍂 Fall Maintenance (Before Heating Season)

1. Replace the Air Filter Again

  • Yes, again. It’s one of the cheapest and most effective ways to extend system life.

2. Inspect the Furnace Burner Flames

  • They should burn blue, not yellow or orange. Weird colors = possible combustion issue.

3. Clean the Flame Sensor

  • Use fine steel wool or an emery cloth to gently remove buildup.

  • Dirty sensors cause no-start issues and shutdowns.

4. Check Carbon Monoxide Detectors

  • Replace batteries and test alarms.

  • This is especially important if you're running a gas furnace.

5. Inspect the Flue Pipe & Vents

  • Make sure there are no signs of rust, blockages, or leaks in your exhaust system.

6. Listen During Startup

  • Any new rattling, banging, or delays in ignition? Get a tech to take a look before winter hits hard.


🧰 Once-a-Year Pro Tune-Up (Spring or Fall)

Some things you shouldn’t DIY unless you’re licensed. Here’s what to ask your HVAC pro to handle during your annual service:

  • ✅ Check refrigerant levels (especially important with R-32 systems)

  • ✅ Test capacitors, contactors, and safety switches

  • ✅ Inspect heat exchanger for cracks or corrosion

  • ✅ Tighten electrical connections

  • ✅ Check static pressure across blower and coil

  • ✅ Clean condensate drain and pan

  • ✅ Verify system startup sequence

  • ✅ Measure supply and return airflow

  • ✅ Review system operation and look for inefficiencies

A good tech will also spot early signs of wear that you can fix before they become major repairs.


🧠 Bonus Tips from Jake

💡 Track Your Energy Bill
A sudden spike in usage (without a big temp change) often signals a maintenance issue.

🧊 Clean the Condensate Drain Line
Pour a cup of vinegar or bleach into the drain line every 6 months to prevent clogs and musty smells.

🧼 Clean the Thermostat Faceplate
Dust on older thermostats can throw off readings. Wipe gently with a microfiber cloth.

🔧 Know Your Warranty Terms
Some manufacturers require proof of annual maintenance to keep your warranty valid.
Keep receipts, and better yet—ask your tech to note the system model and serial number on your invoice.


⏳ Final Word from Jake

Your HVAC system is like your truck: take care of it, and it’ll take care of you. Skip the maintenance, and you’ll be paying for it in repairs—or early replacement—before you know it.

Set two calendar reminders a year—one in spring, one in fall—and make this checklist part of your home routine.
