Quick Tip: Proper HVAC maintenance can lower energy bills by 15% and avoid costly repairs. Follow these steps now to ensure consistent comfort and better air quality throughout the year.

HVAC Systems Maintenance Essential Tips for the Heating Season

Step 1: Book a Professional Check-up

Scheduling professional HVAC check-ups can help your system last longer and work more efficiently. The National Institute of Building Sciences states that regular maintenance can extend the lifespan of HVAC equipment by 15–20% ^[1][2]. In areas with extreme weather, like Dallas/Fort Worth, it’s a smart move to plan bi-annual check-ups – one in the spring for cooling and another in the fall for heating. This helps avoid expensive repairs and keeps your system running smoothly.

What Technicians Check

During a check-up, technicians inspect key parts of your system. Here’s what they focus on and why it matters:

Signs You Need a Pro

Sometimes, waiting for your next scheduled check-up isn’t an option. Call a technician if you notice any of these issues:

• Strange noises like banging, squealing, or grinding
• Odd smells coming from vents
• Weak or uneven airflow
• A sudden spike in your energy bills
• Ice forming on outdoor units during warm weather

Energy Star highlights that regular maintenance can cut yearly heating and cooling costs (which average over $900) by up to 15% ^[1][2]. These savings tie directly into the next step: keeping your filters clean and efficient.

Step 2: Clean or Replace Filters

Keeping your HVAC filters in good shape is key when switching between seasons. A clean filter can boost your system’s efficiency by up to 15% and help lower energy costs^[1][2]. Here’s what you need to know about managing filters during seasonal transitions.

How Often Should You Replace Filters?

How often you change your filters depends on how your system is used. Here’s a quick guide:

Picking the Right Filter

As the seasons change, choosing the right filter is essential. Filters are rated using the MERV (Minimum Efficiency Reporting Value) system, which measures how well they trap particles:

• MERV 1-4: Basic, works for minimal allergens.
• MERV 5-8: A solid choice for typical seasonal changes.
• MERV 9-12: Great for high pollen seasons.
• MERV 13-16: Top-tier, suited for severe allergy concerns.

Seasonal Filter Maintenance

1. Inspect Before the Season Starts

Before switching to heating or cooling, inspect your filters for:

• Heavy dust buildup
• Any bending or warping
• Proper airflow direction

2. Keep an Eye on Performance

Watch for these red flags that might indicate a filter issue:

• Higher energy bills
• Weak airflow
• More dust around your home
• Unusual smells

Always double-check your HVAC unit’s manual or ask a technician to ensure you’re using the right filter for your system^[1][2][4]. Maintaining clean filters also plays a big role in keeping your ductwork running smoothly – more on that next.

Step 3: Check and Fix Ductwork

Inspecting ductwork is crucial for maintaining efficient airflow and avoiding energy waste. Did you know leaky ducts can lose up to 30% of heated or cooled air? ^[1] This not only impacts energy bills but also reduces overall system performance. Before seasonal changes, keep an eye out for these common warning signs:

A study by Oak Ridge National Laboratory in 2022 revealed that sealing ducts properly can reduce air leakage by 74%, leading to 15-20% energy savings for heating and cooling systems ^[1].

Common Duct Problems

Sometimes, professional cleaning is unavoidable. Consider hiring a professional if you notice:

• Mold inside the ducts
• Evidence of pests
• Excessive dust buildup
• A noticeable drop in system performance

Duct Cleaning Options

Companies like Longhorn Services offer all-in-one solutions, combining inspection, cleaning, and sealing during a single visit. While professional cleaning involves upfront costs, it significantly improves both efficiency and indoor air quality.

For DIY maintenance between professional visits, try these tips:

• Clean vent covers monthly to reduce buildup
• Pay attention to unusual sounds, which might indicate leaks
• Use mastic tape to seal small leaks

Taking care of your ductwork ensures better airflow and sets the stage for optimizing your outdoor unit, which is covered in the next step.

Step 4: Clean and Check Outdoor Units

Your outdoor HVAC unit has to endure weather changes, debris, and seasonal wear and tear. A 2023 Johnson Controls study found that homeowners who maintained their outdoor units regularly experienced an 18% drop in energy costs during the summer months ^[2].

Once you’ve ensured your ductwork is in good shape, it’s time to turn your attention to the outdoor unit – your system’s first line of defense against extreme weather.

Key Maintenance Tasks

Here are two essential tasks to keep your outdoor unit running efficiently:

In areas with harsh climates, like Dallas/Fort Worth, dirty condenser coils can increase energy consumption by as much as 30% ^[5]. To keep your unit running smoothly, ensure there’s a 2-foot clearance around it and follow these maintenance tips:

Maintenance Steps

1. Safety and Cleaning
   Before starting, turn off the power to the unit. Use gloves and eye protection for safety. Clean the coils gently with a soft brush and a garden hose. If the dirt is tough to remove, use a coil cleaner recommended by the manufacturer ^[5].
2. Inspect Key Components
   Check these parts for any issues:
   • Refrigerant lines for leaks or damage
   • Electrical connections for wear or looseness
   • Unit casing for rust or damage
   • Condenser fins for bending or damage

A properly maintained system can improve efficiency by 15-20% ^[2].

Warning Signs to Watch For

If you notice any of the following, call a professional right away:

• Ice forming on the unit outside of winter
• A noticeable drop in system performance

Once your outdoor unit is in top shape, you can move on to testing your system to ensure everything is functioning as it should.

Step 5: Run System Tests

Once you’ve optimized the outdoor unit, it’s time to confirm the entire system is functioning properly by running a few key tests.

Check Thermostat Settings

Start by testing the thermostat to ensure it’s accurate and working as expected:

Here’s how to test it:

• Compare the thermostat’s reading with a reliable thermometer.
• Verify that the scheduling feature works as intended.
• Switch between heating and cooling modes to ensure smooth transitions.

Monitor Energy Use

Keep an eye on these performance indicators during your system tests:

Be alert to these potential problems:

• Temperature differences of more than 2°F between rooms.
• The system running longer than 15 minutes to reach the desired temperature.

If you encounter any major issues during these checks, it’s a good idea to reach out to an HVAC professional, like Longhorn Services, for further evaluation. These tests will help you decide whether the system needs professional attention, which we’ll cover in the next step.

Step 6: What to Fix Yourself vs. Call a Pro

After completing system testing in Step 5, it’s time to decide which tasks you can handle on your own and which need professional expertise.

HVAC Task Guide: DIY vs. Pro

Important DIY Safety Tips: Always turn off the power to your system and wear protective gear before starting any maintenance.

When to Call a Professional:

• If your system frequently starts and stops (short-cycling)
• When you notice burning smells
• For refrigerant services regulated by the EPA

“75% of no-heat calls in winter are related to lack of maintenance, many of which could be prevented by DIY checks” ^[2].

Signs That Need Professional Help:

• Water leaks or moisture buildup
• Electrical malfunctions

Knowing what you can handle and when to call in a pro ensures your HVAC system is ready for the season ahead.
