Air Conditioning Repair in Lansing, St. John, Crown Point, Schererville, Cedar Lake, Dyer, Hobart, Munster and Griffith IN

When your air conditioning system starts acting up, recognizing the symptoms early can save you from costly repairs and uncomfortable days without cooling. At Lansing Heating & Air Conditioning Inc., we’ve serviced all HVAC makes and models throughout Chicagoland and Northwest Indiana since our founding in 1971. The most frequent issue we encounter is insufficient cooling, where your AC runs constantly but fails to reach the desired temperature. This often results from dirty air filters restricting airflow, low refrigerant levels due to leaks, or frozen evaporator coils caused by various mechanical failures.

Strange noises coming from your air conditioning unit always warrant immediate attention. Squealing sounds typically indicate belt problems in older units or bearing issues in direct-drive motors. Grinding noises suggest serious motor bearing failures that require urgent repair before complete breakdown occurs. Rattling or banging sounds often point to loose components or debris in the outdoor unit. Our technicians carry comprehensive diagnostic equipment to pinpoint these issues quickly, minimizing downtime and preventing further damage to your system.

AC Repair Diagnostic Procedures

We begin every air conditioning repair service with a thorough system evaluation. Our certified technicians check refrigerant pressures using precision gauges to identify potential leaks or charging issues. Temperature differential measurements across the evaporator and condenser coils reveal efficiency problems and potential blockages. Electrical component testing includes checking capacitors, contactors, and relay switches that commonly fail during peak summer usage. As a Factory Authorized Dealer since 2003, we maintain the highest standards in diagnostic accuracy and repair quality.

Advanced diagnostic tools allow us to detect problems invisible to the naked eye. Thermal imaging cameras reveal hot spots in electrical connections before they fail completely. Digital manifold gauges provide real-time pressure and temperature data, helping identify subtle refrigerant flow issues. Amp draw measurements on compressors and fan motors catch declining efficiency before total failure occurs. This comprehensive approach ensures we address root causes rather than just symptoms, providing lasting solutions for your cooling needs.

Essential Air Conditioning Repair Services We Provide

Refrigerant leak detection and repair represents one of our most critical services. Using electronic leak detectors and UV dye systems, we locate even the smallest leaks in copper lines, evaporator coils, and condensing units. Once identified, we perform proper repairs using industry-approved brazing techniques and materials. After fixing leaks, we evacuate the system to remove moisture and contaminants before recharging with the exact manufacturer-specified refrigerant amount.

Component Replacement and AC Upgrades

When repairs aren’t sufficient, we provide expert component replacement services:

• Compressor replacement: We install exact OEM replacements or approved aftermarket units depending on your system’s age and your budget preferences
• Evaporator and condenser coil replacement: Using proper brazing techniques and nitrogen purging to prevent oxidation inside copper lines
• Control board replacement: Modern systems rely on complex electronic controls that we diagnose and replace with precision
• Fan motor and capacitor replacement: Essential for proper airflow and system efficiency

Preventive Measures and Maintenance Importance

Regular AC maintenance dramatically reduces the need for emergency repairs. We recommend bi-annual tune-ups that include cleaning condenser coils, checking refrigerant levels, testing all electrical components, and verifying proper drainage. During these visits, we often catch minor issues before they escalate into major failures. Our experience as a Carrier Dealer for over 30 years has taught us that well-maintained systems last significantly longer and operate more efficiently throughout their lifespan.

Indoor air quality directly impacts your air conditioning system’s performance and longevity. Dirty filters force systems to work harder, increasing wear on components and energy consumption. We educate our customers about proper filter selection and replacement schedules based on their specific household conditions. Pet owners, allergy sufferers, and homes near construction sites require more frequent filter changes to maintain optimal system performance.

Sometimes deciding between repair and replacement requires careful consideration of multiple factors. We help you evaluate repair costs against the age and efficiency of your current system. Generally, if repair costs exceed 50% of replacement value on systems over ten years old, replacement becomes the wiser investment. Energy efficiency improvements in newer models often offset replacement costs through lower monthly utility bills.

Our commitment to transparency means we provide detailed repair estimates explaining exactly what needs fixing and why. We never perform unnecessary work or recommend repairs that won’t provide lasting value. Let our family take care of your family – this mission statement drives every interaction and service decision we make. Whether servicing homes in Lansing, St. John, Crown Point, Schererville, Cedar Lake, Dyer, Hobart, Munster and Griffith IN or commercial properties throughout the area, we maintain the same high standards that have earned customer trust for over five decades.
