Fall HVAC Preparation North Texas: Winter Readiness Guide

October: When Smart Homeowners Separate from the Emergency Callers

Here’s something that might surprise you: October is my busiest month. Not because everyone’s systems are breaking down - but because the smart homeowners are getting ahead of problems before they become disasters.

Picture this: your AC just finished six months of pure abuse. April through September, battling 100°F+ days, sometimes running nonstop for weeks. Your system is exhausted, components are stretched to their limits, and connections have loosened from months of thermal cycling.

Now you flip a switch and expect your heating system - which has been sleeping peacefully since last March - to fire up and work perfectly.

It’s like leaving your car parked for six months and expecting it to start on the first try during the coldest week of winter.

I’ve tracked this for years: about two-thirds of heating system failures happen within the first few weeks of cold weather. The calls start pouring in right after the first cold front - “My heat won’t come on,” “There’s a weird smell,” or worst of all, “My carbon monoxide detector is going off.”

The thing is, most of these problems started developing months ago. A crack in the heat exchanger doesn’t happen overnight. A gas valve doesn’t just suddenly fail. These issues build up over time, and the first cold weather just reveals what was already broken.

The Double Whammy of North Texas HVAC Life

Your AC Just Survived Boot Camp

Your air conditioning system has been through hell. We had 47 days over 100°F last summer (yes, I counted). That’s 47 days where your system ran almost non-stop, fighting a losing battle against Texas heat.

I’ve been inside these units after a brutal summer - electrical connections come loose from constant heating and cooling cycles, refrigerant leaks develop from stress, and components wear out faster than they would anywhere else in the country.

Your Heating System Has Been Taking a Nap

Meanwhile, your heating system has been sitting idle since March. In a perfect world, that would be fine. But this isn’t a perfect world - it’s North Texas.

Dust settles on everything. Humidity causes corrosion. Spiders build webs in vent pipes (I’ve seen it). Heat exchangers that were fine in the spring might have developed hairline cracks during the summer heat. Gas valves stick. Ignition systems collect dust.

Then, one October morning, you ask this neglected system to suddenly spring to life and keep your family warm. Sometimes it works. Sometimes it doesn’t. Sometimes it works but isn’t safe.

North Texas Climate Factors:

Sudden temperature drops from 85°F to 35°F within 24 hours create extreme thermal cycling that stresses all system components beyond normal operating parameters. High humidity periods create condensation and corrosion issues throughout equipment, particularly affecting electrical connections and metal components that are vulnerable to moisture damage. Dust and allergen accumulation during transitional weather can clog filters and reduce system efficiency when heating operation begins and clean airflow becomes critical. Storm season overlap requires weather-resistant system preparation to protect equipment from potential wind and hail damage during the transitional period when severe weather is common.

Comprehensive Fall HVAC Preparation Checklist

Phase 1: Giving Your AC System a Well-Deserved Check-up

End-of-Season AC Service (What I Actually Do):

First, I Need to Know How Your System Performed This Summer

I start by running diagnostics to see how your system held up. Did it maintain proper refrigerant levels? Are the pressures where they should be? How’s the overall efficiency compared to when I serviced it in the spring?

I document everything because trends tell a story. If your refrigerant is a little low this year, and it was a little low last year, we’ve got a leak that’s getting worse. Better to find it in October when I have time to fix it properly than in July when you’re desperate and I’m booked solid.

I also take pictures of any wear or damage. Not for insurance purposes - for planning purposes. That minor corrosion on your condenser coil? It’s going to be major corrosion next summer. Let’s talk about it now when you can budget for it.

2. Refrigerant System Service

Refrigerant system service involves checking for refrigerant leaks using electronic detection methods to identify any losses that developed during summer operation and prevent future problems. I verify proper refrigerant charge for next season startup by testing pressures and temperatures to ensure optimal performance when cooling resumes after winter dormancy. All refrigerant line connections and joints receive thorough inspection for signs of wear, corrosion, or loosening that could lead to future problems and costly repairs. Testing expansion valve or orifice operation ensures proper refrigerant metering and system efficiency throughout the upcoming cooling season. Documentation of superheat and subcooling values provides baseline performance data for future comparison and troubleshooting when service issues arise.

3. Electrical System Inspection

Electrical system inspection begins with testing all contactors, capacitors, and relays for wear patterns that indicate approaching failure or reduced performance that could lead to system breakdowns. I measure voltage and amperage at all major components to identify electrical issues that could affect system operation or efficiency during peak demand periods. All electrical connections receive checking for corrosion or looseness that developed from months of thermal cycling and vibration throughout the demanding summer season. Wiring inspection covers damage from heat, moisture, or pests that could create safety hazards or system failures when reliable operation is most critical. Testing low-voltage control circuits and thermostats ensures proper communication and response throughout the system for optimal performance and safety.

4. Outdoor Unit Preparation for Winter

Outdoor unit preparation involves thorough cleaning of the condenser coil to remove accumulated summer debris including dust, leaves, and cottonwood that reduces heat transfer efficiency and system performance. I inspect and straighten condenser coil fins that may have been bent by weather or debris, restoring proper airflow for optimal performance when the system resumes operation. Fan motor bearings receive checking and lubrication if serviceable, ensuring smooth operation and extending motor life through the dormant season and into next year. Proper unit mounting and levelness verification prevents vibration and refrigerant line stress that can develop from foundation settling during seasonal changes. The area around the unit gets cleared of debris and vegetation that could restrict airflow or harbor pests during the winter months when systems are not monitored as closely.

Phase 2: Waking Up Your Heating System Safely

Gas Furnace Startup (This is Life-or-Death Serious)

Safety First - Because I Don’t Want to Read About You in the News

Before I even think about firing up your furnace, I’m looking for anything that could hurt you or your family. Heat exchanger cracks are the big one - they can leak carbon monoxide into your home. I use a flashlight and mirror to look at every inch I can see.

Gas leaks are another killer. I soap-test every connection, looking for bubbles that indicate escaping gas. I check the venting system because if exhaust gases can’t get out properly, they’ll come back into your house.

This isn’t paranoia - it’s experience. I’ve found cracked heat exchangers, gas leaks, and blocked vents. I’ve literally saved lives by catching these problems in October instead of November when families are running their systems constantly.

2. Combustion System Service

Combustion system service starts with cleaning the burner assembly and adjusting for proper flame pattern to ensure complete combustion and maximum efficiency throughout the heating season. I test ignition system operation whether pilot light or electronic ignition to verify reliable startup when heating is needed during cold weather. The flame sensor receives cleaning and resistance reading verification to ensure proper flame sensing and safe operation that prevents dangerous conditions. Draft motor operation and venting system performance checking ensures proper exhaust removal and combustion air supply for safe system operation. Complete combustion analysis verifies safe and efficient operation by measuring combustion gases and ensuring proper air-fuel ratios for optimal performance and safety throughout the winter season.

3. Blower and Air Distribution Testing

Blower and air distribution testing begins with inspecting and cleaning the blower wheel and housing to remove accumulated dust and debris that reduces airflow and efficiency during heating operation. I test blower motor operation at all speeds to verify proper performance across the full operating range when heating demands vary throughout the season. Belt-driven systems receive belt tension and condition checking to prevent slipping or breakage during peak operation when reliable airflow is most critical. Proper airflow through the heat exchanger gets verified to ensure adequate heat transfer and prevent overheating that could damage the system or create safety hazards. All limit switches and safety controls undergo testing to ensure they’ll protect the system and occupants from dangerous operating conditions throughout the heating season.

4. Thermostat and Control System Verification

Thermostat and control system verification includes testing thermostat operation in heating mode to ensure proper system response and temperature control when families depend on consistent comfort. I verify proper temperature differential settings to prevent short cycling and ensure comfortable operation that maintains steady indoor temperatures. Programming gets checked and optimized for heating season operation including schedules and setback temperatures that maximize efficiency while maintaining comfort. Heat pump systems receive emergency heat operation testing to verify backup heating functions properly when needed during extreme cold periods. Communication between all system components receives verification to ensure coordinated operation and proper system response to control inputs throughout the demanding heating season.

Don’t Be a November Emergency

Every November, I get frantic calls from families whose heating systems have failed on the first really cold night. Kids are crying, spouses are arguing about who was supposed to schedule maintenance, and everyone’s scrambling to find space heaters.

Don’t be that family.

I’ve been doing this long enough to know that most heating emergencies are completely preventable. The heat exchanger that cracks in November was probably showing stress fractures in September. The gas valve that fails during the first cold snap was probably sticking back in October.

Here’s what I want you to do:

Call me now, while it’s still nice outside. Let me check your system when I have time to do it right, when parts are available, when you’re not desperate.

My fall service isn’t just maintenance - it’s insurance. Insurance that your family will be warm when the temperature drops. Insurance that you won’t be paying emergency rates on a Saturday night in December.

Ready to avoid being a holiday emergency? Call (940) 390-5676 and let’s get your system ready for winter.

I serve all of North Texas - Frisco, Plano, McKinney, Allen, The Colony, Prosper, Little Elm, and everywhere in between. My maintenance customers get priority scheduling and never pay emergency rates.
