Fall in Boise means crisp mornings, colorful leaves, and the first real test of your home’s heating system since last winter.

After sitting idle for months, furnaces and heaters often need attention to keep them running smoothly. At Peppy Heating & Cooling, we see certain heating problems pop up in homes across the Treasure Valley every year once the temperatures start to drop. Understanding these issues can help you catch small problems before they turn into big breakdowns.

Common Heating Problems Boise Homeowners Face

While every heating system is a little different, there are certain issues we encounter again and again during the fall season. These problems range from minor fixes that can be handled in a single visit to major concerns that require urgent professional attention.

Below are the five most common repairs we perform in Boise homes once colder weather sets in.

1. Ignition System Failures

One of the most common reasons a furnace won’t start properly is a problem with the ignition system. Modern furnaces use either hot surface ignitors or intermittent pilot lights, both of which can wear out or fail over time.

• Symptoms include repeated clicking sounds, the furnace struggling to ignite, or the system shutting down soon after starting.
• Replacing an ignitor is usually straightforward, but ignoring the problem can lead to a complete system failure.

If your furnace isn’t firing up consistently, it’s a clear sign you need a professional inspection.

2. Blower Motor Malfunctions

Your furnace’s blower motor is responsible for pushing heated air through your ductwork and into your living spaces. When it’s not working correctly, you’ll notice weak or uneven airflow throughout the home.

• Early signs include rattling or squealing noises, inconsistent heating between rooms, or the furnace running without blowing much air.
• Left unresolved, a failing blower motor can cause the system to overheat and shut down completely.

Routine maintenance, including cleaning and lubrication, often extends the life of this critical part.

3. Thermostat Problems

Sometimes the issue isn’t with the furnace itself but with the thermostat controlling it. Boise homeowners often call us for heating repairs when their thermostat is miscalibrated, malfunctioning, or simply placed in the wrong spot in the home.

• Signs of thermostat trouble include rooms not reaching the set temperature, short cycling (frequent on/off cycling), or unresponsive controls.
• While some thermostat issues can be solved with new batteries or recalibration, others may require replacement with a newer, more accurate model.

A professional can help determine if your thermostat is the problem or if it’s signaling deeper system issues.

4. Dirty or Clogged Filters

Clogged air filters are one of the simplest yet most damaging causes of heating issues. A dirty filter restricts airflow, forcing your furnace to work harder and increasing the risk of breakdowns.

• Symptoms include reduced airflow, hot and cold spots in your home, and higher energy bills.
• In some cases, a dirty filter can even cause the furnace to overheat and shut off as a safety precaution.

Replacing your filter every 1 to 3 months is one of the easiest ways to avoid heating repair calls in the fall.

5. Worn or Failing Heat Exchanger

The heat exchanger is the heart of your furnace. Over time, it can crack due to repeated heating and cooling cycles. This isn’t just a performance issue—it can also pose serious safety risks if not addressed.

• Warning signs include strange odors when the furnace is running, soot buildup inside the furnace, or an unexplained rise in carbon monoxide levels.
• Repairing or replacing a heat exchanger is complex and should only be handled by a licensed HVAC professional.

Because of the potential dangers, regular furnace maintenance is crucial for spotting heat exchanger issues early.

Why Heating Repairs Are So Common in Fall

When fall arrives in Boise, homeowners switch on their furnaces after months of sitting idle. Dust, wear-and-tear, and undetected problems from the previous season all reveal themselves at once. The sudden demand on your system combined with colder nights makes this one of the busiest times of the year for heating repair calls.

Scheduling a professional tune-up before the season begins can help catch many of these issues early, saving you money and stress later on.

How to Prevent Frequent Heating Repairs

While not every breakdown can be avoided, you can reduce the likelihood of unexpected heating problems by taking a few proactive steps:

• Schedule annual maintenance with a licensed HVAC company.
• Replace air filters regularly.
• Keep vents and registers clear of furniture and obstructions.
• Listen for unusual sounds and call for service at the first sign of trouble.

These simple steps can make a big difference in the comfort and efficiency of your home during Boise’s chilly fall and winter months.

Attempting advanced DIY furnace repairs can lead to dangerous situations, voided warranties – or even a complete system failure.

In this guide, Peppy Heating & Cooling outlines tasks homeowners can safely tackle, common troubleshooting tips, and clear indicators that it’s time to call an HVAC expert.

Safe DIY Furnace Tasks You Can Handle at Home

Most DIY furnace repairs revolve around basic maintenance tasks that can improve efficiency and reduce the risk of costly breakdowns. These steps can often resolve minor issues and extend the lifespan of your heating system.

1. Replace the Air Filter

Changing the air filter is the easiest and most impactful task you can do. A clogged filter restricts airflow, forcing your furnace to work harder and increasing your energy bills. Aim to replace the filter every 1-3 months, depending on usage and filter type.

2. Clean Furnace Components

Dust and debris can collect in and around your furnace, impacting performance. Use a vacuum with attachments to clean vents, registers, and around the furnace housing. For extra cleaning, gently wipe accessible components with a soft cloth or brush.

3. Inspect the Thermostat

Ensure your thermostat is set to “eat” mode and that the temperature setting is above room temperature. Replace the batteries if needed and check for dust buildup that could interfere with its operation.

4. Check the Power Source

Verify the furnace is receiving power. Reset tripped circuit breakers and ensure the power switch near the unit is in the “on” position. For gas furnaces, check that the gas valve is open and the pilot light is lit.

Tools Every Homeowner Needs for Furnace Maintenance

Stock your toolkit with these essentials for safe and effective furnace maintenance:

• A digital thermometer for checking air temperature.
• A screwdriver set for accessing panels and components.
• A vacuum with attachments to clean vents, registers, and surrounding areas.
• Replacement air filters 
• A wire brush for cleaning burners.
• A flashlight to inspect hard-to-see areas.
• Safety gloves and a dust mask to protect yourself.

When To Call an HVAC Professional

While basic maintenance and troubleshooting can solve some problems, certain situations require professional expertise to avoid injury, further damage, or safety risks.

Contact a licensed HVAC technician if you encounter any of the following:

• Gas odors or carbon monoxide alerts. These are serious hazards that require immediate professional attention.
• Electrical issues or burning smells, AKA signs of wiring problems or overheating components.
• Strange noises, like grinding, squealing, or banging, that can indicate mechanical failures.
• Frequent cycling. If the furnace is turning on and off rapidly, it could mean a failing thermostat, clogged filter, or other issues.
• Yellow or flickering pilot light may point to ventilation or gas issues.
• No heat despite troubleshooting. If basic steps don’t resolve the issues, it’s time to call a technician.
• Unusually high energy bills. This could signal that your furnace is working harder than necessary due to inefficiencies.

Furnace Maintenance Tips to Prevent Repairs

Regular maintenance is key to avoiding unexpected breakdowns and costly repairs. Be sure that you’re scheduling your annual inspections before the major seasons to ensure your system is in peak condition.

Additionally, you’ll want to:

• Keep vents and registers clear of obstructions.
• Seal air leaks in ductwork to improve efficiency.
• Monitor your system for unusual changes in performance.

Does your home feel perpetually chilly during winter? If you’re searching for affordable ways to keep your home warm without investing in a costly zoned heating system, you’re in the right place.

Here are practical tips to help keep your home cozy without overspending.

1. Upgrade to Smart Thermostats

If you’re still relying on standard thermostats, you’re missing out BIG time. Modern smart thermostats let you control your home’s temperature from your phone or another connected device – wherever you are.

• Set the temperature lower when you’re away and schedule it to warm up before you return.
• Keep your thermostat at 72 degrees when you’re home and between 62 and 68 degrees when you’re out to lower heating costs.

2. Seal Drafty Windows and Doors

Did you know that houses lose a significant amount of energy through their doors and windows? To fix them:

• Install weatherstripping around the edges of windows and doors to block cold air.
• Use thick, thermal curtains to add an extra layer of insulation.

A quick test: Move your hand around window and door frames to feel for drafts. If you notice cold air, sealing those gaps can make a big difference!

3. Insulate Your Home Properly

Well-insulated attics, walls, and floors help homes retain heat better, keeping you warm without overworking your heating system. While installation can be pricey, depending on the type you choose, this is one upgrade that’s always worth the money!

For colder climates, experts recommend insulation with an R-value of 49 or higher. Fiberglass insulation with an R-value of 60 is a great option for maximum efficiency.

4. Use Space Heaters Wisely

If you mostly spend most of your time in just a few rooms, consider using space heaters instead of heating your entire home.

• Place space heaters in frequently used rooms to stay comfortable while reducing the load on your central heating system.
• Always follow manufacturer instructions and never leave a space heater unattended.

5. Schedule Regular HVAC Maintenance

If you’ve ever had to call for furnace repairs, you know just how expensive it can be to get your heating system working again. The best way to prevent those costly repairs is to schedule HVAC maintenance once a year – preferably before you need to use your system.

HVAC maintenance is such a big money saver because you’ll find little problems before they necessitate wallet-draining repairs, or even a full system replacement.
