Fall Preparation Tips for Your HVAC and Plumbing Systems

The air is turning crisp in Northern Indiana, and before long, the first frost will arrive in South Bend, Granger, and the surrounding areas. Fall is a season of change, cozy sweaters, football games, and comfort food, but it’s also the perfect time to prepare your home for the colder months ahead.
At Cavinder, we know that a little preparation now can help prevent breakdowns, frozen pipes, or surprise repair bills later. Here are some expert fall preparation tips for your HVAC and plumbing systems to keep your home safe, warm, and worry free all season long.


HVAC Tips for a Trouble Free Fall

Your furnace and heating system will soon become the hardest working equipment in your home. These steps go beyond the basics and focus on safety, efficiency, and longevity.

  1. Check the furnace ignition and flame sensor
    Why it matters: A dirty flame sensor is one of the top reasons older furnaces suddenly stop working.
    How to do it safely: Turn off power to your furnace at the breaker, remove the flame sensor (usually held in by one screw), and gently clean it with a fine emery cloth. If you’re uncomfortable, have a professional do this during a tune up.
  2. Inspect and seal ductwork leaks
    Why it matters: Leaky ducts can waste up to 30% of heated air, leaving some rooms cold while your furnace overworks.
    How to do it safely: Visually inspect exposed ducts in basements or crawlspaces. Use mastic sealant or foil HVAC tape (never standard duct tape) to cover gaps. For large leaks or hidden ducts, call a pro for a pressure test.
  3. Test your carbon monoxide detectors
    Why it matters: Furnaces and gas appliances run more often in fall and winter, raising the risk of carbon monoxide leaks.
    How to do it safely: Press the test button to confirm your detectors work. Replace batteries yearly, and replace the unit itself every 5 to 7 years as recommended by the manufacturer.
  4. Evaluate your system’s efficiency
    Why it matters: Rising bills, uneven heating, or strange noises are signs your furnace may be struggling, especially if it’s 15+ years old.
    How to do it safely: Track your utility bills and take note of performance changes. Schedule a fall inspection if you suspect issues before heavy use begins.
  5. Clear the condensate drain line
    Why it matters: High efficiency furnaces produce water that drains through a small PVC pipe. A clogged line can shut down your system or cause leaks.
    How to do it safely: Turn off the furnace, locate the drain line, and flush it with a mixture of vinegar and warm water. If the clog persists, call a technician.

Plumbing Tips to Prevent Winter Woes

Northern Indiana winters are hard on plumbing. Frozen pipes and water damage are costly, but these preventative steps can help you avoid headaches.

  1. Insulate exposed pipes
    Why it matters: Pipes in basements, garages, or crawlspaces are vulnerable to freezing.
    How to do it safely: Use foam insulation sleeves or heat tape rated for plumbing. Make sure insulation fits snugly without gaps.
  2. Drain and disconnect outdoor faucets
    Why it matters: Water left in hoses or spigots can freeze, expand, and burst pipes inside your walls.
    How to do it safely: Disconnect garden hoses, shut off the interior valve leading to the outdoor faucet (if your home has one), and open the faucet to drain remaining water.
  3. Check for leaks and drips
    Why it matters: Even a slow drip can freeze and worsen in winter, leading to costly damage.
    How to do it safely: Inspect under sinks, toilets, and around your water heater. Look for water stains, corrosion, or musty odors. Fix small leaks quickly or call a plumber before cold weather hits.
  4. Flush your water heater
    Why it matters: Sediment buildup reduces efficiency and can shorten the lifespan of your water heater.
    How to do it safely: Turn off power or gas to the heater, attach a hose to the drain valve, and empty a few gallons into a bucket until the water runs clear. If unsure, have a plumber handle it.
  5. Test your sump pump
    Why it matters: Heavy fall rains and melting snow can cause basement flooding.
    How to do it safely: Pour a bucket of water into the sump pit to make sure the pump activates. Check that the discharge line is clear and directs water away from your foundation.
