Preparing Your HVAC System for Extreme Weather: Essential Steps for Homeowners and Businesses

When the forecast promises blazing heat or biting cold, your HVAC system becomes the heart of your home or business. You rely on it to keep your family, employees, and customers safe and comfortable—no matter what’s happening outside. But when extreme weather hits, HVAC systems are pushed to their limits. A little preparation goes a long way.

At Briggs Heating, we know that emergencies don’t wait for a convenient time. That’s why preparing your system for the unexpected is not just smart—it’s essential.

Why Prepare Your HVAC for Extreme Weather?

Imagine your HVAC system as the goalie in a high-stakes game. When the weather turns wild, that goalie faces a barrage of shots—heatwaves, freezes, storms, and power outages. Without the right prep, even the best systems can get overwhelmed.

Seasonal and emergency preparation helps you:

• Prevent costly breakdowns during the worst possible moments
• Extend the life of your HVAC equipment
• Maintain safe, healthy indoor air quality
• Reduce energy bills by improving efficiency
• Protect your property from damage caused by leaks, freezing, or overheating

According to the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), regular maintenance and emergency readiness are key factors in HVAC longevity and safety.

Seasonal HVAC Maintenance Tips for Summer and Winter ☀️❄️

Extreme temperatures can strain even the toughest systems. Here’s how to help your HVAC equipment weather the storm—literally.

Summer Preparation

• Change Air Filters: Dirty filters block airflow, making your AC work harder. Swap them every 1–3 months.
• Clear Outdoor Units: Remove leaves, grass, and debris from around your condenser. Keep at least two feet of clearance.
• Check Thermostat Settings: Program your thermostat for comfort and efficiency. Consider a smart thermostat for automatic adjustments.
• Inspect Ductwork: Look for visible gaps or loose connections. Leaky ducts waste cool air and spike energy bills.
• Test System Early: Run your AC before the first heatwave. Listen for odd noises and check for weak airflow.
• Schedule Professional Maintenance: A licensed technician can spot trouble before it ruins your summer.

Winter Preparation

• Replace Filters Again: Clean filters help your furnace breathe and prevent overheating.
• Seal Drafts: Weatherstrip doors and windows. Insulate exposed pipes near HVAC lines to prevent freezing.
• Check Vents and Registers: Make sure nothing blocks airflow—furniture, rugs, or dust.
• Test the Furnace: Turn it on before the first freeze. Watch for strange smells or noises.
• Inspect Carbon Monoxide Detectors: Replace batteries and test alarms. Gas furnaces should be checked annually for safety.
• Professional Tune-Up: A pro will inspect burners, heat exchangers, and safety controls.

Emergency Readiness: Power Outages, Storms, and 24/7 Service ⚡

When the lights go out or a storm rolls in, your comfort and safety depend on preparation.

Generator Maintenance and Backup Power

• Test Standby Generators: Run your generator monthly. Check fuel, oil, and battery levels.
• Install Transfer Switches: Prevent dangerous backfeeds and protect utility workers.
• Keep Fuel Safe: Store fuel in approved containers, away from heat sources.
• Know Your Load: Only connect critical systems—HVAC, refrigeration, medical equipment.

Emergency HVAC Contacts

• Save Our Number: Program Briggs Heating into your phone for fast emergency hvac help.
• List Other Essentials: Keep contacts for utility companies, plumbers, and electricians handy.

Storm-Proofing Tips

• Secure Outdoor Units: Fasten AC condensers and cover them if high winds are expected.
• Protect Electronics: Use surge protectors for thermostats and control boards.
• Clear Gutters and Drains: Prevent water backup near HVAC components.

Spotting Early Warning Signs of HVAC Stress

Your HVAC system will often whisper warnings before it shouts for help. Stay alert for:

• Unusual Noises: Banging, screeching, or rattling can signal loose parts or motor trouble.
• Weak Airflow: Could mean clogged filters, failing blower motors, or duct leaks.
• Short Cycling: If your system turns on and off rapidly, it’s struggling to keep up.
• Odd Smells: Burning, musty, or rotten egg odors require immediate attention.
• Rising Energy Bills: A sudden spike often means your system is working overtime.

If you notice any of these, it’s time to call for a professional assessment before things get worse.

The Benefits of Professional HVAC Inspections and Preventive Maintenance

DIY can only take you so far. Certified HVAC technicians follow industry best practices, including those set by ASHRAE, the U.S. Department of Energy, and the Occupational Safety and Health Administration (OSHA).

What Pros Check During a Maintenance Visit

• Inspect and clean coils, burners, and heat exchangers
• Test safety controls and electrical connections
• Measure refrigerant levels and check for leaks
• Assess airflow and balance the system
• Calibrate thermostats and sensors
• Check for carbon monoxide leaks (for fuel-burning systems)
• Review overall system performance and efficiency

Why Preventive Plans Matter

A maintenance plan isn’t just a calendar reminder. It’s a shield against surprise breakdowns and expensive repairs. Regular visits catch small issues before they snowball. They also ensure your system runs efficiently, saving you money and stress.

Practical Tips for Homeowners and Small Businesses

• Change filters regularly. Mark your calendar or set a phone reminder.
• Keep vents and returns unblocked. Rearrange furniture if needed.
• Monitor humidity levels. Too much or too little can strain your system and affect comfort.
• Install surge protectors. Protect sensitive HVAC electronics from power spikes.
• Know your system’s age. Older units may need more frequent checkups.

Reducing Risk: Indoor Air Quality and Safety

Extreme weather can trap pollutants indoors or increase allergens. Good indoor air quality (IAQ) matters for health and comfort.

• Install air scrubbers or purifiers to capture dust, pollen, and bacteria.
• Schedule duct cleaning to remove buildup that can worsen allergies or asthma.
• Test for carbon monoxide and radon as recommended by the EPA.
• Maintain humidity with dehumidifiers or humidifiers, depending on the season.

Costs and Time Factors: What to Expect

• Routine maintenance: Usually takes 1–2 hours per system.
• Emergency repairs: May take longer, especially during severe weather or high-demand periods.
• Replacement parts: Availability can be affected by storms or supply chain issues.
• Preventive maintenance: Typically costs less than emergency repairs or full replacements.

Investing in regular care is like changing the oil in your car—cheaper than a new engine.

When It’s an Emergency: What to Do

• Stay calm. Turn off your system if you smell gas, hear electrical buzzing, or see smoke.
• Call for emergency hvac service. Don’t wait—delays can lead to bigger problems.
• Follow safety guidelines. Evacuate if there’s a fire, gas leak, or carbon monoxide alarm.
• Document issues. Take notes or photos for insurance or repair records.

Briggs Heating offers 24/7 emergency service because we know problems don’t stick to business hours.

Frequently Asked Questions

How often should I schedule HVAC maintenance?

Twice a year—once in spring for cooling and once in fall for heating. If you have special systems (like geothermal or radiant heat), check your manufacturer’s guidelines.

Can I perform any maintenance myself?

Yes! Change filters, keep vents clear, and check thermostat batteries. Leave electrical and mechanical work to licensed professionals.

What should I do if my system stops during a storm?

First, check your breakers and thermostat. If the problem isn’t obvious and easy to fix, call for emergency hvac help. Avoid DIY repairs on electrical or gas systems.

How do I know if my indoor air quality is poor?

Look for persistent dust, musty smells, allergy symptoms, or visible mold. Professional IAQ testing can pinpoint hidden problems.

Special Considerations for Your HVAC System

• Older buildings may need updated wiring or ductwork to handle modern HVAC loads.
• Businesses with sensitive equipment (like servers or refrigeration) should have backup power plans in place.
• Homes with young children, elderly, or health concerns should prioritize air quality and temperature stability.
• Geothermal and radiant systems need specialized maintenance—always use qualified technicians.
