Is your home a haven or an oven? A sanctuary or a sweatbox? When your HVAC system goes silent in the dead of winter—or hums only warm air in the peak of July—it’s more than an inconvenience. It’s a scramble. That’s why, at Platts Heating & Air, we know homeowners need more than a quick fix. You need a plan.

Our HVAC maintenance checklist is your roadmap to fewer surprises, lower costs, and a more comfortable home. Not just when things break, but all year round. Let’s dig in.

Why Regular HVAC Maintenance Matters 🛠️

Think of your HVAC system like the heart of your home. When it’s healthy, everything flows—heat, cool, clean air. But skip a beat (or a filter change), and you might be staring down a costly emergency hvac call.

Benefits of routine care:

  • Lower energy bills: A clean, tuned system works less to keep you comfortable.
  • Fewer breakdowns: Catch small issues before they become big, sweaty (or shivery) problems.
  • Longer equipment life: Just like a car, simple upkeep makes your investment last.
  • Better air quality: Dust, pollen, and even mold are less likely to build up.
  • Peace of mind: No one likes surprise cold showers or sleepless summer nights.

The U.S. Department of Energy and manufacturers like Trane and Lennox both recommend regular, seasonal HVAC maintenance to get the most from your system.

Monthly, Seasonal, and Annual Tasks

Big fixes start with small, steady steps. Here’s what you should do—and when.

Monthly Checklist

  • Change or check air filters: Especially if you have pets or allergies. Dirty filters block airflow and strain your system. Most manufacturers recommend every 1–3 months.
  • Inspect vents and registers: Make sure they’re open and nothing’s blocking them (furniture, dust bunnies, toys).
  • Check thermostat settings: Small kids (or curious guests) can bump the settings without you knowing.

Seasonal Checklist

Spring & Summer

  • Clear debris from outdoor units: Leaves, grass, and branches can choke your AC’s condenser. Trim back plants at least two feet.
  • Check the condensate drain: A clogged drain can lead to water leaks and mold.
  • Test your AC: Run it a few weeks before hot weather hits. Listen for odd noises and sniff for strange smells.

Fall & Winter

  • Change humidifier pads: If you use a whole-house humidifier, swap the pad before heating season.
  • Inspect your furnace or heating system: Look for rust, dust, or odd smells.
  • Test your generator: If you have one, make sure it starts up and runs smoothly.

Annual Checklist

  • Schedule a professional tune-up: We recommend two per year: once before heating season and once before cooling season.
  • Have ducts cleaned: Every 3–5 years, or sooner if you have allergies, pets, or recent renovations.
  • Review your energy bill: Spikes can signal something’s off.

DIY vs. Professional Service

You wouldn’t try to fix your car’s transmission with a kitchen knife. Some HVAC tasks are simple. Others need a skilled hand.

What Homeowners Can Do

  • Change filters
  • Vacuum vents and registers
  • Keep the area around equipment clean
  • Reset tripped breakers

If you’re comfortable, you can also:

  • Swap thermostat batteries
  • Clean the visible parts of your AC’s outdoor unit (after turning off power)

When to Call Platts Heating & Air

  • Annual tune-ups or home energy audits
  • Refrigerant checks or recharges (it’s illegal to handle refrigerant without a license)
  • Radiant Heating near you acting up
  • Strange noises, odd smells, or visible rust
  • Sudden spikes in your energy bill
  • Indoor air quality testing, dehumidifiers, or air scrubbers installation

Manufacturers like Carrier and Goodman specify that professional maintenance is required to keep warranties valid.

Prevention & Maintenance

Prevention isn’t glamorous. But it’s a lot cheaper than emergency hvac repairs at 2 a.m.

Proactive steps:

  • Set reminders for filter changes
  • Keep pets groomed to reduce fur buildup
  • Don’t ignore odd noises or smells
  • Keep HVAC equipment clear of boxes, laundry, and clutter

Remember, homes with radiant heating, whole-house fans, or mini-splits need attention too. Each system has its own quirks—check the manufacturer’s manual for specific tips.

Costs & Time Factors

How much time does this all take? Not as long as you think.

  • Filter changes: 5–10 minutes
  • DIY cleaning: 15–30 minutes
  • Professional maintenance: 1–2 hours per visit

Costs vary depending on your system’s age, size, and needs. But regular maintenance can save hundreds—or even thousands—by preventing breakdowns and extending the life of your HVAC equipment.

When It’s an Emergency

Sometimes, you can’t wait. If your heating or cooling stops working during extreme weather, or you smell gas, hear grinding, or notice water leaks—call for emergency hvac help. Don’t risk your family’s health or safety.

Red flags:

  • No heat or AC when you need it most
  • Water pooling around your furnace or AC
  • Burning smells or electrical odors
  • Strange, loud noises from vents or equipment
  • Carbon monoxide alarms sounding

Platts Heating & Air is on-call 24/7 for those moments when you can’t wait. Your comfort and safety come first.

FAQ: HVAC Maintenance

How often should I change my filter? Most homes need a new filter every 1–3 months. More often with pets or allergies.

Is duct cleaning really necessary? If you see dust buildup, smell musty odors, or have unexplained allergy symptoms, it’s worth considering every 3–5 years.

Can I install my own thermostat? Some smart thermostats are DIY-friendly, but professional installation ensures correct wiring and optimal performance.

What’s the lifespan of a typical HVAC system? With regular maintenance, most systems last 12–20 years. Neglect can shorten that dramatically.

Local/Seasonal Considerations 🍂

Your location shapes your HVAC needs. In humid climates, dehumidifiers fight mold and musty odors. In drier regions, whole-house humidifiers protect wood floors and ease breathing. If you live where storms are frequent, generator installation and maintenance keep you safe when the grid goes down.

If you’re searching for “Radiant Heating near you” or want to improve your indoor air quality, remember: what works in one home may not work in another. Always consider local weather, home size, and personal comfort needs.
