HVAC maintenance is a routine inspection and tune-up of your heating and cooling system. During a maintenance check, a certified technician examines, cleans, tests, and adjusts your equipment to ensure everything runs safely and efficiently. 

Why it matters: 

Prevents breakdowns / Lowers energy bills / Extends system lifespan / Improves indoor air quality / Keeps the system running safely

Maintenance is the best way to protect your home and your budget!

Most experts recommend servicing your HVAC system twice a year:

• Once in the spring for your air conditioning
• Once in the fall for your heating system

This ensures your equipment is prepared for the heavy-use seasons ahead.

While each company may vary slightly, most professional tune-ups include:

• Inspecting and cleaning coils
• Changing or checking air filters
• Checking refrigerant levels
• Testing electrical connections
• Inspecting the blower motor
• Checking thermostat performance
• Lubricating moving parts
• Clearing drains
• Checking for leaks or worn parts

A good technician will also explain any issues and recommend repairs before they become bigger — and more expensive — problems.

Yes! Regular maintenance helps your system operate more efficiently, which means it uses less energy to heat or cool your home. A clean, well-tuned system can cut energy costs by up to 10–15%.

Even more importantly, maintenance helps prevent major breakdowns and extends the life of your equipment. That alone can save you thousands of dollars over time.

 In many cases, yes. Most manufacturers require proof of regular professional maintenance to keep the system’s warranty valid. If you skip tune-ups, you may be responsible for repair costs that would otherwise be covered. 

Look for warning signs like:

• Strange smells or noises
• Weak airflow
• Uneven temperatures
• Higher energy bills
• Longer heating or cooling times
• The system turning on and off frequently

These may signal clogged filters, failing parts, airflow issues, or electrical problems — all things a tune-up can address early.

You can — and should — complete simple tasks such as:

• Changing your air filters regularly
• Keeping outdoor units clear of debris
• Cleaning vents and registers

But professional checks are essential for safety and longevity. Many components require specialized tools, testing equipment, and training.

The ideal times are:

• Spring (March–May) for AC
• Fall (September–November) for heating

Scheduling early helps you avoid seasonal rushes and ensures your system is ready before extreme temperatures hit.
