Regular air conditioning maintenance is the single most important thing you can do to prevent mid-summer breakdowns, extend system life, and keep energy bills under control. L & H Services Inc. has been maintaining air conditioning systems in Beecher, Frankfort, Crete, and throughout Southern Chicago since 1979—over 45 years of keeping residential and commercial AC systems running reliably.
Our comprehensive maintenance visits catch small problems before they become expensive failures, clean components that accumulate efficiency-robbing dirt, and optimize performance for maximum comfort and minimal operating costs. Don't wait for your AC to fail—preventive maintenance is always cheaper than emergency repairs.
Think of air conditioning maintenance like oil changes for your car—regular service prevents problems, catches issues early, and protects your investment. L & H Services Inc. provides comprehensive AC maintenance that goes far beyond basic filter changes, thoroughly inspecting and servicing every component that affects performance, efficiency, and reliability.
Our maintenance services address both immediate needs (cleaning dirty coils, testing failing components, correcting minor issues) and long-term reliability (identifying components nearing failure, documenting system condition, advising about future needs).
Air conditioning systems don't fail randomly—most breakdowns result from gradual deterioration that routine maintenance would have caught early. Failing capacitors show weakness before complete failure. Refrigerant leaks start small and worsen over time. Electrical connections loosen gradually. Dirt accumulation restricts airflow incrementally.
During maintenance visits, we identify these developing problems while they're still minor and inexpensive to address. A small part replaced during maintenance prevents a costly emergency service call when it fails completely on the hottest weekend of summer.
Air conditioners typically last 15-20 years with proper maintenance, but only 10-12 years when neglected. The difference? Dirt accumulation forces systems to work harder, increasing wear and component stress. Minor problems left unaddressed cause collateral damage to other components.
New air conditioners lose approximately 5% efficiency each year without maintenance due to dirt accumulation, refrigerant loss, and component wear. After just 3-4 years without service, a high-efficiency system operates at standard-efficiency levels—wasting hundreds of dollars annually in excess energy costs.

Annual AC maintenance is affordably priced for residential systems, with pricing varying based on system type, accessibility, and whether you have a maintenance plan. Our maintenance plans offer the best value, bundling annual service with priority emergency service, discounted repairs, no overtime charges, and other benefits. The cost is minimal compared to a single emergency repair or premature equipment failure from neglect.
Most residential central air conditioning systems need professional maintenance once per year before cooling season (April or May). Heat pumps providing both heating and cooling should receive service twice yearly—spring before cooling season and fall before heating season. Commercial systems operating longer hours benefit from semi-annual or quarterly maintenance. Older systems (12+ years) benefit from more frequent service as components age.
Our comprehensive maintenance visits include 20+ point inspections and services: outdoor coil cleaning, electrical connection inspection and tightening, capacitor and contactor testing, refrigerant pressure testing, compressor amp draw testing, indoor coil inspection, condensate drain cleaning, blower motor testing, filter inspection, temperature split measurement, airflow assessment, thermostat verification, complete visual inspection, and clear communication of all findings with recommendations for any issues discovered.
While homeowners should change filters monthly and keep the outdoor unit clear of debris, comprehensive AC maintenance requires professional expertise, specialized tools, and technical knowledge. Tasks requiring professional service include refrigerant pressure testing (requires EPA certification), electrical component testing (safety hazard for untrained persons), amp draw measurements (requires proper equipment), coil cleaning (improper methods damage fins), and system performance assessment (requires experience and diagnostic tools).
Skipped maintenance guarantees higher energy bills (15-25% higher from dirt accumulation), dramatically shortened equipment life (fail 30-50% sooner), certain mid-summer breakdowns (typically during the hottest weather), and possible voided warranty coverage (many manufacturers require proof of maintenance). The money "saved" by skipping maintenance gets wasted many times over through higher energy costs, premature failures, and expensive emergency repairs.
Yes—most air conditioning problems develop gradually and aren't obvious until they cause complete failures. Refrigerant leaks start small. Capacitors weaken before failing completely. Electrical connections loosen gradually. Coils accumulate dirt imperceptibly. By the time problems become obvious, damage is often extensive and expensive. Maintenance catches these developing problems while they're still minor. Don't wait for problems—prevention is always cheaper than repair.
While maintenance dramatically reduces repair needs by catching problems early, it cannot prevent all failures. Air conditioners contain components with finite lifespans—capacitors, contactors, and fan motors eventually wear out even with perfect maintenance. However, maintenance-related failures are typically predictable (we warn you components are weakening), happen at convenient times rather than during heat waves, and cost less because they're addressed early before causing collateral damage.
Comprehensive professional maintenance typically requires 1-1.5 hours for residential systems, depending on equipment accessibility, system condition, and issues discovered. We don't rush through maintenance visits—thorough inspections take time to perform correctly. We'll schedule service at your convenience and complete work efficiently while maintaining our quality standards. You should be home during the visit so we can explain findings and answer questions.
Absolutely. Properly maintained air conditioners last 15-20 years compared to 10-12 years when neglected—a 30-50% lifespan extension. The reason is simple: clean systems work less hard (reducing wear), minor problems get caught before causing major damage, refrigerant charge is maintained protecting the compressor, and electrical connections stay tight preventing arcing and control damage. Over a system's life, this extended lifespan saves thousands of dollars.
April or May is ideal for air conditioning maintenance—before cooling season begins but after spring weather arrives. This timing identifies problems before summer heat, avoids peak-season scheduling challenges when HVAC companies get slammed with emergencies, and ensures your system is ready when temperatures soar. Some homeowners also benefit from fall maintenance if they run AC into September/October or have heat pumps requiring heating season preparation.
For most homeowners, yes. Our maintenance plans bundle annual professional service with valuable benefits: priority emergency service (jump to front of line during failures), discounted repair pricing (save 10-15% on parts and labor), no overtime charges on emergency calls, service reminders, and complete service history tracking. Plans typically pay for themselves the first time you need emergency service or repairs. Over several years of home ownership, plan benefits save hundreds to thousands compared to paying for everything separately.
Yes, significantly. Clean, properly-maintained air conditioners use 15-25% less energy than neglected systems with dirty coils, improper refrigerant charge, and worn components. Maintenance can save a significant portion of your annual cooling costs—often exceeding the cost of maintenance itself. Over a 15-20 year system lifespan, efficiency savings from regular maintenance add up to thousands of dollars.
