Regular HVAC maintenance isn’t just “nice to have”—it’s the key to system longevity, indoor comfort, and lower utility bills. Yet many homeowners and business owners don’t know how often they should service their HVAC system.

So, what’s the right HVAC maintenance schedule for Texas homes and commercial buildings?

At Tarrant Mechanical, we help DFW clients stay ahead of costly repairs and breakdowns with customized service plans. Here’s what you need to know.

Why HVAC Maintenance Matters

Before we talk frequency, let’s quickly cover why servicing your HVAC system is so important:

  • Improves energy efficiency
  • Prevents breakdowns and emergency repairs
  • Extends system lifespan
  • Keeps your warranty valid
  • Maintains good indoor air quality

Skipping tune-ups can cost you more in the long run—not just in repair bills, but also in comfort and energy usage.

General Rule: Twice a Year

The HVAC industry standard is to service your system twice a year:

  • Spring – Prepare your air conditioner for the Texas heat
  • Fall – Tune up your heater before colder weather hits

This schedule ensures your equipment is ready for the seasons when it works hardest.

Residential HVAC Service Schedule

For DFW homeowners, we recommend:

✔ Spring HVAC Tune-Up

  • Clean evaporator and condenser coils
  • Check refrigerant levels and pressure
  • Inspect and tighten electrical connections
  • Calibrate thermostat
  • Test airflow and temperature split

✔ Fall HVAC Tune-Up

  • Check and clean burners or heat exchangers
  • Inspect blower assembly
  • Check for carbon monoxide leaks
  • Lubricate moving parts
  • Replace or clean filters

Bonus Tip: Change air filters every 30–90 days for best performance.

Commercial HVAC Service Schedule

Commercial HVAC systems often run more frequently and support larger spaces—so service needs increase.

Tarrant Mechanical recommends:

  • Quarterly HVAC inspections for retail, office, or restaurant spaces
  • Monthly filter changes for high-traffic environments
  • Biannual full tune-ups with ductwork inspections and system diagnostics

We tailor plans based on:

  • Building size
  • System type (zoned, rooftop, VRF, etc.)
  • Industry needs (e.g., healthcare, server rooms, food service)

Signs You’re Overdue for Service

Not sure if your system needs attention? Look for these red flags:

  • Higher than normal energy bills
  • Uneven heating or cooling
  • Poor airflow or noisy operation

If any of these sound familiar, schedule service ASAP—don’t wait for a full breakdown.
