👋 Why You Can’t Skip the Annual Tune-Up 

Here’s the deal, one quick appointment a year can mean 10 more years of system life, and it might be the difference between a $200 cleaning and a $5,000 replacement.

Most folks wait until the system breaks. The smart ones? They prevent breakdowns in the first place.

According to Integrity Heating & Cooling, professional maintenance reduces the risk of breakdowns by up to 95% and maintains manufacturer warranty validity.

Your HVAC system should be tuned up:

• Once per year at minimum
  

• Ideally in spring (for AC) and fall (for heat)

• Especially if it’s still under warranty (like Goodman’s 10-year parts coverage)

📋 The HVAC Tune-Up Checklist: What Pros Actually Do 

Here’s what a real HVAC technician (like me) checks during a tune-up. If they skip these, get someone else.

🔥 Heating System (Gas or Electric)

Safety & Combustion (Gas Units):

• Inspect heat exchanger for cracks using specialized cameras  
• Clean burners and test flame sensor operation
• Verify ignition system (hot surface igniter or pilot)
• Confirm proper gas pressure with manometer
• Test carbon monoxide levels
  

Electrical & Mechanical:

• Lubricate blower motor bearings
• Check and tighten all electrical connections
• Test limit switches and safety shutoffs
• Measure amp draw on motors
• Verify proper sequencer operation (electric furnaces)
  

❄️ Cooling System (if integrated with HVAC)

• Clean condenser coils
• Measure refrigerant charge and superheat/subcooling
• Check fan motors and capacitors
• Inspect drain pan and condensate line for clogs
  

🧩 Shared System Tasks

• Test thermostat operation and calibration
• Inspect ductwork for visible air leaks
• Replace or inspect air filter (depends on agreement)
• Measure airflow and static pressure

🔧 What You Can Prep Before the Visit 

You don’t need to lift the hood, but here’s how you can help your tech (and your wallet):

• Replace your filter ahead of time
  

• Clear boxes or furniture from around the unit
  

• Take notes on weird noises, smells, or air quality

• Make sure your thermostat has batteries (yes, that happens often)
  

💡 Pro Tip: Ask your tech to label duct zones if your home has multiple returns. It helps long term!

⚠️ What Happens If You Skip Maintenance

You’d be surprised how many people wait until their system completely fails before calling. 

The National Fire Protection Association reports that heating equipment is involved in 1 in 7 home fires. Here's what develops when you skip annual service: 

• Coils clog, leading to higher energy bills
  

• Motors overheat from low airflow
  

• Flame sensors fail, shutting down heating on cold nights
  

• Warranty becomes void due to missing maintenance records

• Small fixes ($100–$200) snowball into full replacements ($3,000–$8,000)
  

Preventative maintenance is 10x cheaper than reactive repairs.

🔗 Mike's Advice And What to Read Next

If your HVAC has been “running fine” for a few years without a tune-up, that’s luck, not a plan.

I’ve replaced systems that failed at 8 years old just because nobody touched them. Don’t let that be you.

❓FAQ

Q: How often should I get a tune-up?

A: Once per year, minimum. Twice is better (spring + fall).

Q: Does this apply to electric furnaces too?

A: Absolutely. While there's no combustion, electric systems still need airflow, blower care, thermostat calibration, and dust cleaning.

Q: Will a tune-up really extend the life of my system?

A: Yes. You’ll avoid heat exchanger cracks, refrigerant damage, and seized blower motors.

Q: What certifications should I look for?

A: NATE-certified technicians are ideal. Make sure they’re licensed, insured, and well-reviewed.
