What’s Included in a Professional HVAC Maintenance Visit?
TLDR:
A professional HVAC maintenance visit includes a detailed inspection, cleaning, testing, and calibration of your system's components like coils, filters, refrigerant levels, and thermostat. These services ensure your HVAC system runs efficiently, prevents costly breakdowns, and prolongs equipment life.
What Is a Professional HVAC Maintenance Visit?

A professional HVAC maintenance visit is a scheduled service where a certified technician thoroughly inspects, cleans, and tests your heating and cooling system to ensure safe and efficient operation.
Unlike DIY maintenance, a professional visit involves specialized tools, diagnostic testing, and industry knowledge that most homeowners don’t have access to.
Most HVAC experts—including our team at Legacy Heating & Air—recommend maintenance visits at least twice a year: once in the spring (for AC) and once in the fall (for heating).
At a glance, professional HVAC maintenance includes:
- Full inspection of system components
- Thermostat calibration
- Air filter replacement
- Electrical connection checks
- Coil and blower cleaning
- Lubrication of moving parts
- Refrigerant level checks
- Startup and shutdown performance testing
Why Is HVAC Maintenance Important?

Regular HVAC maintenance isn’t just about keeping the unit clean—it directly impacts energy efficiency, indoor air quality, and long-term cost savings.
Here’s why maintenance matters:
- Improves energy efficiency: Clean systems work less to achieve the same temperature, lowering utility bills.
- Prevents breakdowns: Regular check-ups catch small issues before they become major repairs.
- Extends system lifespan: Like changing the oil in your car, routine maintenance reduces wear and tear.
- Keeps your warranty valid: Most manufacturers require annual maintenance to uphold warranties.
- Enhances indoor air quality: Clean filters and coils mean fewer airborne pollutants circulating through your home.

FAQs About HVAC Maintenance
How often should HVAC maintenance be done?
Ideally twice a year—spring for cooling systems, fall for heating systems.
Can I skip a maintenance visit if my system seems fine?
Skipping can lead to undetected issues, lower efficiency, and potential warranty voiding.
Can I do HVAC maintenance myself?
Basic upkeep (like filter changes) is fine, but full servicing should be done by a licensed technician.
Does HVAC maintenance really improve air quality?
Yes. Clean filters, ducts, and coils reduce allergens, dust, and mold growth.
What to Look for in a Professional HVAC Technician

Not all technicians offer the same level of quality or reliability. Here’s what to look for when hiring a pro:
- Licensing and certification: Look for NATE certification or state-level licensing
- Experience: A good technician should be well-versed in multiple system types
- Checklist transparency: Reputable companies like
Legacy Heating & Air provide a service report detailing everything inspected and performed
- Customer service: Punctuality, professionalism, and a willingness to explain issues go a long way
Common Issues Found During HVAC Maintenance

During a typical visit, technicians often find issues that homeowners had no idea existed:
- Dirty or clogged coils: Restrict airflow and lower efficiency
- Blocked condensate drain lines: Can lead to water damage or mold
- Low refrigerant: Reduces cooling effectiveness and strains the compressor
- Worn belts or motors: Lead to poor airflow or total system failure
- Loose electrical connections: Pose fire risks and performance issues
Catching these issues early can prevent high repair costs later on.
