DIY HVAC and Plumbing Maintenance Tasks for Homeowners This Summer
Summer is the season when your home’s HVAC and plumbing systems work hardest. Your air conditioner runs daily to keep you cool, while plumbing fixtures get extra use from outdoor activities, guests, and garden watering. The good news? You don’t have to be a professional to keep things running smoothly.
At Lake Michigan Heating, Cooling & Plumbing, we believe in empowering homeowners to take control of their home maintenance. Here’s a list of simple, effective summer tasks you can handle on your own to avoid costly breakdowns and keep your systems efficient and reliable all season long.
HVAC Maintenance Tasks You Can Do Yourself
1. Change Your Air Filter
One of the easiest—and most impactful—tasks is replacing your HVAC filter. A clean filter improves airflow, reduces strain on your system, and helps keep your indoor air clean.
- When to do it: Every 1–3 months, more often if you have pets or allergies
- What to use: Check your current filter size and replace it with the same type; consider a higher MERV rating if indoor air quality is a concern
Need help choosing the right filter? We can help you upgrade your system for better comfort and cleaner air.
2. Clean Around the Outdoor Condenser Unit
Your AC’s outdoor unit needs plenty of airflow to function properly. Grass clippings, leaves, and dirt can block airflow and reduce efficiency.
- What to do:
- Turn off power to the unit
- Gently remove debris by hand or with a garden hose (never use a pressure washer)
- Trim back plants or shrubs at least 2 feet from the unit
3. Inspect Your Thermostat
Check that your thermostat is working correctly and accurately reflects the indoor temperature. If it’s programmable or smart, update your settings to reflect summer hours or vacation plans.
- Bonus tip: Set your thermostat to 78°F when you’re home and higher when away to save energy without sacrificing comfort.

4. Check Vents and Registers
Ensure that all supply and return vents in your home are open and unobstructed by furniture, curtains, or rugs.
- What to do:
- Wipe down vents to remove dust
- Vacuum around them to improve airflow
- Don’t close vents in unused rooms—this can create pressure imbalances
5. Look for Unusual Sounds or Odors
If you hear banging, squealing, or rattling from your HVAC system—or notice musty or burning smells—it could be a sign of a mechanical issue or dirty components.
- Next step: Shut off the system and schedule a service visit if anything seems off.
Plumbing Maintenance Tasks You Can Handle This Summer
1. Check for Leaks
Summer is a great time to inspect all visible plumbing for leaks or signs of moisture.
- What to do:
- Look under sinks, behind toilets, and around water heaters
- Check outdoor spigots and hoses for drips
- Monitor your water bill for sudden spikes
If you find a slow leak, replacing washers or tightening connections can often solve the problem. If not, our licensed plumbers are ready to help.
2. Flush Your Water Heater
Sediment buildup in your water heater can reduce efficiency and shorten the unit’s lifespan—especially with increased summer usage.
- How to flush it:
- Turn off power or gas to the unit
- Attach a hose to the drain valve
- Drain a few gallons of water into a bucket or to an outdoor area
- Turn the unit back on when done
If your water heater is more than 10 years old, it may be time for an upgrade. We install energy-efficient water heaters that keep up with your household needs.
3. Clean Faucet Aerators and Showerheads
Mineral buildup from hard water can reduce water pressure and clog fixtures.
- What to do:
- Unscrew the aerator or showerhead
- Soak it in vinegar for 30–60 minutes
- Scrub gently with a toothbrush
- Rinse and reinstall
4. Test Outdoor Plumbing
Check garden hoses, irrigation systems, and outdoor spigots for leaks or damage.
- Tips:
- Replace worn hoses and washers
- Use a shutoff nozzle to conserve water
- Insulate exposed outdoor lines if you notice high water pressure changes
5. Clean and Test Your Sump Pump
With summer storms common in Michigan, your sump pump is your first line of defense against basement flooding.
- What to do:
- Pour a bucket of water into the sump pit to ensure the float switch activates the pump
- Listen for smooth operation and quick drainage
- Clean the pump and pit of debris or mud buildup
We offer sump pump inspections and battery backup systems if yours is older or unreliable.
Bonus Tip: Schedule a Professional Tune-Up
