AC Maintenance in Gwinnett County

Your air conditioning system works hard during Georgia's hot summers, running constantly to keep your home cool and comfortable. Without regular maintenance, that strain takes a toll. AC maintenance is the single best investment you can make to keep your cooling system running reliably, efficiently, and cost-effectively throughout the season.

Think of AC maintenance like car maintenance. Regular oil changes and inspections prevent engine failure. Similarly, regular AC tune-ups prevent system breakdowns, reduce energy consumption by 15-20%, extend your system's lifespan, and save you thousands in emergency repairs.

At Henson Mechanical, we've completed thousands of AC maintenance visits across Georgia. Our technicians know exactly what to check, what to clean, and how to optimize your system for peak performance.

Why AC Maintenance Matters:

Prevents Costly Breakdowns: Regular maintenance catches 80% of potential problems before they become system failures. A clogged filter or low refrigerant can be fixed during maintenance for $50-$150. Let it go, and you're facing a $500-$2,000 emergency repair on the hottest day of the summer when you desperately need your AC.

Improves Energy Efficiency: A well-maintained AC system runs 15-20% more efficiently than a neglected one. That translates to:

• $30-$60 less per month on cooling costs
• $360-$720 annual savings
• Over 10 years: $3,600-$7,200 in energy savings
• A spring maintenance costing $150 pays for itself in just 2-3 months

Extends System Lifespan: A maintained AC unit lasts 18-20 years. A neglected unit might only last 12-15 years. Maintenance adds 3-5 years to your system's life, delaying the need for expensive replacement.

Maintains Warranty Coverage: Many manufacturers require annual maintenance to honor the warranty. Skipping maintenance could void your coverage.

Improves Indoor Air Quality: Clean filters and coils remove dust, pollen, and allergens. Proper AC maintenance improves the air you breathe.

Ensures System Safety: AC systems are complex. Professional inspection verifies electrical safety, proper refrigerant levels, and that all components function safely.

What's Included in Professional AC Maintenance:

Our comprehensive AC maintenance includes 20+ inspection and cleaning tasks:

Filter & Airflow:

• Inspect and replace air filter (or clean if reusable)
• Check ductwork for leaks or blockages
• Verify proper airflow throughout the home
• Check return air vents aren't blocked

Refrigerant & Pressure:

• Measure refrigerant levels (should be within manufacturer specs)
• Check for signs of refrigerant leaks
• Verify proper pressures on high and low sides
• Top off refrigerant if needed (and identify/repair any leaks)

Coil Cleaning:

• Inspect evaporator coil (inside unit) for dust and debris
• Inspect condenser coil (outside unit) for dirt buildup
• Clean coils to restore heat transfer efficiency
• Check drain pan and drain line for blockages

Electrical Components:

• Test thermostat calibration (verify it reads accurate temperature)
• Inspect capacitors for signs of failure
• Test contactor switches
• Check wiring connections for corrosion or damage
• Verify proper electrical voltage to all components

Mechanical Components:

• Lubricate motors and bearings (reduces friction and wear)
• Inspect fan blades for damage or imbalance
• Check refrigerant lines for cracks or damage
• Inspect mounting brackets and vibration isolation

System Function Testing:

• Run system in cooling mode and verify proper operation
• Check temperature differential (air coming from vents should be 15-20°F cooler than return air)
• Verify compressor cycles on/off properly
• Check for unusual noises or vibrations
• Confirm thermostat controls system properly

Safety Verification:

• Ensure outdoor unit has proper airflow (no debris, plants)
• Check electrical safety (no exposed wires, proper grounding)
• Verify gas lines (if applicable) are secure and not leaking

Documentation & Reporting:

• Provide detailed report of system condition
• Document any repairs performed
• Note any components needing attention
• Recommend future maintenance or upgrades

Spring AC Maintenance Timing:

Schedule AC maintenance in April or early May—before summer heat arrives and before demand spikes. Early spring maintenance ensures:

• Your system is ready when summer hits
• We can schedule at your convenience (not rushed during peak season)
• You have time to address any issues before you need cooling daily
• You avoid the emergency repair rush and higher rates

Waiting until June when it's hot? You risk being without AC for days while we handle emergency calls.

DIY AC Care Between Professional Maintenance:

You can help keep your system running well between professional visits:

Monthly (During Cooling Season):

• Check and replace filters (every 1-3 months depending on household conditions)
• Visually inspect outdoor unit for debris
• Ensure indoor vents and returns aren't blocked

Quarterly:

• Clean outdoor condenser unit coils (gently with garden hose)
• Trim vegetation around outdoor unit (maintain 2-foot clearance)
• Wipe down indoor supply vents

Seasonally:

• Before summer: Ensure outdoor unit is clear and ready
• Before fall: Schedule fall furnace maintenance to prepare for winter

What NOT to Do:

• Don't open the outdoor unit (refrigerant is pressurized; improper handling is dangerous)
• Don't attempt to repair electrical components
• Don't use liquid drain cleaners (damage pipes)
• Don't ignore strange noises or weak cooling (call for service)

Signs You Need AC Maintenance NOW:

• It's been over a year since last service
• Your energy bills have increased gradually
• Your AC isn't cooling as effectively as it once did
• You hear unusual noises (hissing, grinding, rattling)
• Airflow from vents is weaker than normal
• You notice ice buildup on outdoor unit (indicates refrigerant leak or airflow problem)
• You haven't replaced the filter in months

The Bottom Line:

A spring AC maintenance costing $150 provides:

• 15-20% improvement in energy efficiency (saving $30-$60/month)
• 80% probability of preventing breakdowns
• Peace of mind knowing your system is ready for summer
• Extended system lifespan (3-5 additional years)

It's the best return on investment you can make for your HVAC system.
