It's easy to overlook heating maintenance when you use air conditioning 10 months of the year. However, gas furnaces and heat pumps that sit idle for long periods often develop hidden issues—rusted heat exchangers, clogged burners, or seized motors—that only reveal themselves when you first turn the...

Why Winter Maintenance Matters in Houston
Safety is the primary concern. A cracked heat exchanger in a gas furnace can leak deadly carbon monoxide into your workspace. Efficiency is second; a neglected system works harder to heat your building, driving up energy costs. Finally, reliability is crucial—Houston's power grid strains during freezes, and an efficient HVAC system places less load on your electrical infrastructure.
Professional Winter Maintenance Checklist
Our licensed technicians perform a rigorous inspection to ensure your system is safe and ready. Here is what our commercial winter maintenance includes:
Safety & Heating Inspection
- Heat Exchanger Analysis: Inspecting for cracks, rust, or corrosion that could allow carbon monoxide leaks.
- Burner Assembly Cleaning: Removing soot and debris to ensure efficient, clean combustion.
- Gas Pressure Calibration: Adjusting gas valve pressure to manufacturer specifications for optimal heat output.
- Ignition System Check: Testing hot surface igniters or pilot assemblies for reliable startup.
- Safety Controls Testing: Verifying limit switches, flame sensors, and rollout switches function correctly.
Electrical & Mechanical Checks
- Belt Inspection: Cold weather makes rubber belts brittle. We inspect for cracks and proper tension.
- Motor Lubrication: Oiling bearings to prevent seizing during cold starts.
- Thermostat Calibration: Ensuring heating schedules match your winter operating hours.
- Economizer Testing: Verifying dampers modulate correctly to use free outdoor cooling when possible.
DIY Maintenance Steps for Business Owners
Between professional visits, facility managers should perform these tasks to keep systems running smoothly:
1. Change Air Filters Monthly
Heating systems recirculate indoor air constantly. Clogged filters restrict airflow, causing the heat exchanger to overheat and the system to short cycle. Check filters every 30 days.
2. Check Thermostat Settings
Ensure your thermostats are switched to "Heat" or "Auto" and that the programmed schedule reflects any changes in winter operating hours (e.g., holiday closures).
3. Clear Outdoor Units
Remove autumn leaves, pine needles, and trash that may have accumulated around rooftop units or ground condensers. Good airflow is essential for heat pumps.
4. Inspect Vents
Ensure supply and return vents aren't blocked by furniture, inventory, or seasonal decorations. Blocked vents disrupt airflow balance and reduce comfort.
Preparing for a Houston Freeze
When a hard freeze is forecast, take these specific actions to protect your HVAC investment:
- Keep Systems Running: Don't turn the heat off completely at night. Set it to at least 60-65°F to keep warm air circulating and prevent building pipes from freezing.
- Insulate External Lines: Ensure foam insulation on refrigerant lines is intact to prevent energy loss and freezing.
- Check Condensate Lines: Ensure drain lines effectively drain water away to prevent freezing and backups.
Don't wait for the first freeze to find out your heater doesn't work. Schedule your commercial winter maintenance with HVAC247PRO today.
Frequently Asked Questions
AYes, absolutely. While Houston winters are mild, gas furnaces that sit idle for 9 months can develop safety issues like rusted heat exchangers, clogged burners, or pest infestations. Professional maintenance ensures your heating system operates safely and efficiently when those sudden cold snaps hit.
AWe recommend monthly filter checks and changes during winter. Heating systems recirculate indoor air more intensively, often picking up dust and allergens. Clean filters protect your heat exchanger from overheating and improve indoor air quality for your employees.
ASkipping heating maintenance increases the risk of carbon monoxide leaks (from cracked heat exchangers), fire hazards (from dust buildup on burners), and unexpected breakdowns. It also voids many manufacturer warranties and leads to higher energy bills as the system struggles to heat efficiently.
AYes, modern commercial heat pumps are effective even in freezing temperatures. However, they rely on clean outdoor coils to absorb heat. If coils are dirty or the defrost cycle malfunctions, the unit can freeze up, leaving your building without heat. Maintenance ensures the defrost controls are working correctly.
AInsulate any exposed refrigerant lines or condensate drains outdoors. During hard freeze warnings, keep your commercial system running (even at a lower setting) rather than turning it off; the circulation helps prevent freezing. Ensure your condensate drain lines are clear so water doesn't trap and freeze.
