Winter HVAC Maintenance Tips for Texas Homes

Tips to Maintain Your HVAC System During the Winter in Texas

Temperature fluctuations force your heating system to work harder than usual. Nobody wants their system breaking down during the coldest nights. Our simple maintenance tips will help your HVAC system run well throughout winter. Murray AC serves homeowners across the Greater San Antonio area. Let us show you how to protect and optimize your system’s performance this season.

Important Pre-Winter HVAC Maintenance Steps

Your HVAC system needs proper maintenance to be winter-ready. A well-kept system can save you money on heating costs and prevent breakdowns during cold months.

Professional inspection checklist

Professional HVAC inspection protects you from winter troubles. Murray AC’s technicians will check all key components during our visit to your home. A professional inspection has these key points.

Electrical Connections: Tightening and testing all connections
Control Systems: Verifying proper starting and shutdown cycles
Moving Parts: Checking and lubricating all components
Heat Exchanger: Inspecting for cracks and proper function
Thermostat: Testing settings and calibration

Filter replacement guidelines

Homes without pets need filter replacement every 90 days. Homes with pets should change it every 60 days. Those with multiple pets or family members who have allergies need new filters every 20-45 days.

Cleaning and lubrication requirements

Clean components and proper lubrication are helpful to your system’s efficiency. Dirty filters can restrict airflow, which forces your system to work harder and raises costs. Moving parts need lubrication to reduce motor friction and keep the system running.

Note that systems without proper care often fail before their expected 10-15 year lifespan. This maintenance routine prepares your system for winter and protects your investment while keeping your family comfortable through the cold season.

Protecting Your Outdoor HVAC Components

Texas weather puts your outdoor HVAC unit through hard conditions, from intense heat to sudden cold snaps. The right protection will give your system a longer life and better results during winter months.

Proper condenser unit coverage

Your outdoor unit needs the right kind of protection despite its tough build. A common mistake is wrapping the unit completely in plastic, which traps moisture and leads to rust. The best solution is a breathable cover that protects just the top, with about a foot of space from the ground to get proper airflow.

Debris removal and maintenance

Your unit needs space to operate at its best. Keep a clearance of two to three feet on all sides and five feet overhead. A good maintenance routine should have these things.

Clearing leaves, twigs, and grass clippings
Cleaning condenser fins with a soft brush
Cutting back nearby plants and vegetation

A soft-bristled vacuum attachment works well to clean stubborn dirt from the unit’s exterior. Never use a pressure washer because it can harm sensitive components.

Weatherproofing techniques

Smart weatherproofing requires more than simple coverage. Place your unit away from potential ice fall zones and create drainage areas around its base. Watch these key areas during severe weather.

Remove snow and ice buildup quickly to prevent freezing
Clear any icicles that form above the unit
Keep at least 18 inches of space after snowfall

Murray AC’s certified technicians can help protect your outdoor HVAC components. We know Texas weather’s challenges and will keep your system protected throughout winter.

Indoor System Optimization

Your indoor HVAC system needs to keep you cozy during unpredictable Texas winters. You can optimize your system’s performance and efficiency with these strategies.

Thermostat programming strategies

The right temperature setting combines science and practical comfort. The Department of Energy recommends 68°F as the ideal temperature for winter days when you’re home. You can reduce your annual heating costs if you lower the temperature 7-10 degrees for eight hours while you sleep or work.

Ductwork inspection and sealing

Your duct system loses 20-30% of moving air because of leaks, holes, and poor connections. These warning signs indicate duct problems.

Rooms feel too hot or too cold
Utility bills spike higher than normal
Spaces remain stuffy and uncomfortable
Exposed ductwork shows visible damage

Humidity control measures

Your home’s winter humidity level should stay between 30-40%. Low indoor air humidity often causes dry skin, itchy eyes, and sore throats. Regarding home damage, it can also cause cracking wooden floors or furniture. A whole-house humidifier merges with your HVAC system and provides consistent optimal humidity levels.

Emergency Preparedness for Texas Winter

Winter emergencies can catch anyone off guard even if you have perfect maintenance. A solid backup plan will keep your family warm and safe during unexpected temperature drops.

Backup heating options

Your heating system needs a backup. Here are some proven options that work well.

Portable space heaters for spot heating
Gas logs or wood stoves for whole-room warmth
Backup generators sized for your HVAC needs

Safety First: Portable heaters must stay at least three feet away from furniture. Your gas stove should never serve as a heater. It creates dangerous conditions and releases harmful carbon monoxide.

Common winter HVAC issues

These typical winter problems can disrupt your comfort at home.

Short cycling (system turning on and off frequently)
Uneven heating across rooms
Strange noises like banging or hissing
Weak airflow from vents

An unexplained spike in energy bills might signal your system’s struggle to maintain temperature. This warning sign often appears before major breakdowns.
