DIY Maintenance Tips Every Homeowner Should Know

Keeping your home comfortable all year doesn’t have to be complicated or expensive. Whether you’re dealing with our typical soggy Western Washington winters or the occasional summer heatwave, a few simple habits can go a long way in keeping your heating, cooling, and ventilation systems running smoothly. 

Why Maintenance Really Matters

It Could Save You Thousands in Repairs

Here’s something to keep in mind: the $5,000 rule. If the age of your HVAC system multiplied by the cost of repairs exceeds $5,000, it might be time to consider a replacement. But regular upkeep can delay that decision by years. Clean filters, clear drain lines, and seasonal check-ins all help extend the life of your system.

It Helps You Stay Ahead of Bigger Issues

Think of it like changing the oil in your car. Staying on top of routine maintenance prevents wear and tear from building up and leading to breakdowns. The same principle applies to heating, cooling, roofing, and even solar systems.

Western Washington Brings Unique Challenges

With all the rain, moss, fluctuating temperatures, and seasonal storms, the local climate is tough on homes. That’s why regular maintenance here isn’t optional—it’s essential.

Your Monthly Maintenance Checklist

Just a few minutes each month can help prevent thousands of dollars in damage, so here’s a handy checklist of a few small steps you can take toward preventing those time and money consuming repairs. To keep your HVAC running in top condition, you should:

  • Replace or clean HVAC filters
  • Check windows and doors for air leaks or moisture buildup
  • Clear debris from your roof and gutters
  • Look for standing water near outdoor HVAC units
  • Test smoke and carbon monoxide detectors

DIY Maintenance You can Perform Yourself

Change Filters Often

Dirty filters are the #1 reason for poor airflow and system inefficiency. Replace them every 1 to 3 months, depending on your system and indoor air quality. Look for ENERGY STAR-certified filters for better performance.

Dial in Your Thermostat Settings

If you haven’t already switched to a smart thermostat or programmable thermostat, now’s the time. These help manage energy usage more efficiently, especially in seasons when it’s tempting to constantly adjust the temperature. Try 68°F in winter and 78°F in summer when you’re home.

Clear Around Your Outdoor Unit

Keep a 2-foot clearance around your outdoor unit. Trim back any shrubs or overgrown plants and clear out leaves and debris so your system can breathe.

Take the “20-Degree Rule” Under Consideration

Here’s a quick test: If your cooling system isn’t bringing the indoor temperature down by about 20 degrees compared to the air outside, it’s not operating efficiently. That could mean dirty coils, blocked vents, or low refrigerant, all of which should be addressed sooner than later.

Tools You Should Have on Hand

Some of these simple maintenance tasks require tools, but there’s no need to go overboard. A few basics will cover most of your routine tasks:

  • Flashlight
  • Replacement filters
  • Screwdrivers and soft brush
  • Ladder with stabilizer (for gutters and roof checks)
  • Work gloves and safety glasses

Bonus tip: Use a home maintenance app to track what’s done and what’s next.

Maintenance Hacks

Even if you’re busy, staying on top of home maintenance is possible with a few simple strategies. Start by setting calendar reminders for seasonal tasks—these gentle nudges help you stay on track without having to remember everything. Keep a digital log of filter changes and service appointments so you can track what’s been done and when. When time is tight, focus on the high-impact areas first: filters, vents, roof inspections, and sealing up air leaks. These small efforts, done consistently, can prevent expensive repair bills down the road.

When It’s Time to Call In a Pro

You don’t have to do it all, and some things are better left to trained technicians. Scheduling a professional tune-up once or twice a year helps your system stay reliable when you need it most. Here are a few items that you can hand off to us:

  • Diagnosing refrigerant issues
  • Checking electrical connections
  • Inspecting the blower motor and capacitor
  • Running a full preventive maintenance checklist

Closing Up

Taking care of your home doesn’t mean tackling every repair or upgrade alone. A few good habits, the right tools, and a clear seasonal plan go a long way toward making your space more efficient, safe, and comfortable.
