HVAC Maintenance & Tune-Ups
Most “no heat” and “no AC” calls don’t start as emergencies — they start as small problems that get ignored until the system fails on the hottest or coldest day of the year. Our HVAC preventative maintenance is built to catch those issues early, keep your system running efficiently, and help you avoid surprise breakdowns.
If you’re in Fort Smith, Spiro, Pocola, Poteau, Sallisaw, Van Buren, Greenwood, Alma, Charleston, or surrounding areas, Clark HVAC makes it easy to keep your comfort on track with seasonal HVAC maintenance and tune-ups.
Why HVAC Preventative Maintenance Is Worth It
Preventative maintenance isn’t just “checking boxes.” A proper tune-up protects your comfort, your budget, and your equipment:
• Fewer breakdowns: We look for the common failure points before they fail.
• Lower stress on the system: Clean airflow + clean coils = less strain and better performance.
• Better comfort: More consistent temperatures, stronger airflow, fewer hot/cold spots.
• Healthier indoor air: Cleaner filters and components help reduce dust and airborne buildup.
• Longer equipment life: Reducing wear and catching issues early helps your system last longer.
• Safer operation: Especially important for heating season (electrical and safety checks matter).
What’s Included in a Clark HVAC Maintenance Visit
We tailor every maintenance visit to your exact system type (AC, heat pump, gas furnace, electric air handler, package unit, mini-split, etc.), but a standard visit typically includes:
Airflow & Filtration
• Inspect filter condition and replace or clean (customer-provided or we can supply)
• Check airflow and look for restriction points that reduce efficiency
• Inspect return and supply condition for common airflow issues
Thermostat & System Operation
• Verify thermostat operation and accuracy
• Confirm proper start-up and shutdown sequence
• Check system controls and safe operation
Electrical & Mechanical Inspection
• Inspect electrical connections and components for signs of wear/overheating
• Tighten connections as needed
• Inspect motors and moving parts and address abnormal noise/vibration
• Verify safe operation of key components
Condensate & Drain Protection
• Inspect condensate drain, pan, and safety switches (where applicable)
• Clear and flush drains to help prevent clogs, overflow, and water damage
• Check for signs of moisture issues that can create odor or humidity problems
Coils, Outdoor Unit, and Performance
• Inspect evaporator and condenser coil condition
• Clean accessible coil surfaces as needed to restore performance
• Check outdoor unit condition (debris, clearance, fan operation)
• Verify refrigerant system health (and identify signs of underperformance)
Heating-Specific Checks (During Heating Season)
• Inspect heating components for safe, reliable operation
• Verify proper heating performance and look for early warning signs of failure
• Confirm correct system operation so you don’t get stuck without heat when you need it
Common Problems Preventative Maintenance Helps Catch Early
These are the issues that most often turn into expensive breakdowns if ignored:
• Dirty coils and restricted airflow (high bills, weak cooling/heating)
• Clogged drain lines (water damage, humidity problems, float switch trips)
• Loose or overheating electrical connections (intermittent failures and safety risks)
• Worn components that are close to failing (before they leave you without comfort)
• Airflow problems that make a good system perform like a bad one
Maintenance Plans (One-Time Tune-Up or Seasonal Program)
You can schedule a one-time HVAC tune-up anytime — but most homeowners get the best results with seasonal maintenance:
• Spring AC tune-up: Get your system ready before summer heat hits.
• Fall furnace/heat pump tune-up: Make sure your heating is reliable before cold weather.
• Twice-a-year maintenance plan: The easiest way to stay ahead of breakdowns year-round.
Maintenance plan members may receive benefits like priority scheduling and discounts on repairs (ask us what’s included in the current plan options).
How Often Do You Need HVAC Maintenance?
Most systems should be serviced 2 times per year, for the best performance and reliability.
• Spring for cooling
• Fall for heating
If your system runs year-round (heat pump), you have pets, allergies, older equipment, or higher usage, seasonal preventative maintenance becomes even more important.
