Understanding AC Repair Needs in Irving’s Climate

When your air conditioning system fails during an Irving summer, where temperatures regularly soar above 100 degrees Fahrenheit, you need immediate and reliable repair service. At M.B. Kiser Heating and Air Conditioning Co. Inc., we’ve been responding to these urgent cooling needs since 1945, making us the oldest AC company in Dallas and the surrounding areas. Our extensive experience in Irving has taught us that air conditioning problems rarely announce themselves at convenient times, which is why we maintain 24/7 availability through our dedicated call center. When you call after hours, our staff picks up your information and forwards it directly to our on-call technician and service manager, ensuring you receive prompt attention. If the situation allows, we’ll call you first thing in the morning to schedule your repair at the earliest possible time.

The unique weather patterns in Irving create specific challenges for air conditioning systems that require experienced technicians who understand local conditions. The combination of extreme heat, high humidity levels reaching 80% during summer mornings, and sudden temperature swings can strain even well-maintained AC units. Our technicians have witnessed firsthand how Irving’s clay-rich soil can shift during drought conditions, potentially affecting outdoor unit placement and refrigerant lines. Additionally, the area’s frequent thunderstorms and occasional hail can damage outdoor condensing units, requiring immediate professional assessment and repair to prevent further system degradation.

Common AC Problems We Address

Throughout our decades of service as the oldest Carrier dealer in Dallas, we’ve diagnosed and repaired virtually every type of air conditioning problem that can occur in residential and light commercial systems. Refrigerant leaks remain one of the most frequent issues we encounter, often manifesting as reduced cooling capacity, ice formation on evaporator coils, or unusually high electric bills. These leaks can develop in multiple locations throughout the system, including the evaporator coil, condensing unit, or the copper refrigerant lines connecting these components. Our certified technicians use advanced leak detection equipment, including electronic leak detectors and UV dye systems, to pinpoint the exact location of refrigerant loss, ensuring comprehensive repairs that restore your system’s efficiency.

Electrical component failures represent another significant category of AC repairs we handle daily in Irving homes and businesses. These issues range from failed capacitors that prevent motors from starting, to worn contactors that cause intermittent operation, to damaged circuit boards that disrupt the entire system’s functionality. Each electrical component plays a crucial role in your air conditioning system’s operation, and our technicians carry extensive inventories of replacement parts to minimize downtime. We also frequently address compressor problems, which can develop due to electrical issues, refrigerant problems, or simply age-related wear after years of operation in Irving’s demanding climate.

Our Comprehensive Repair Process

When you contact M.B. Kiser Heating and Air Conditioning Co. Inc. for AC repair service, we follow a systematic diagnostic approach developed through our seven-plus decades of experience. Our process begins with a thorough visual inspection of your entire system, including both indoor and outdoor components. We examine the condition of your air filter, check for obvious signs of damage or wear, and assess the cleanliness of coils and other heat exchange surfaces. Our technicians then proceed to operational testing, measuring temperatures at supply and return vents, checking refrigerant pressures, testing electrical components with specialized meters, and evaluating airflow throughout your ductwork system.

• System performance analysis: We measure superheat and subcooling values to assess refrigerant charge accuracy and system efficiency
• Electrical diagnostics: We test all electrical components including capacitors, relays, contactors, and motors using professional-grade testing equipment
• Mechanical inspection: We evaluate fan motors, belts, bearings, and other moving parts for proper operation and signs of impending failure

Preventive Strategies and Maintenance Benefits

Our extensive experience serving Irving, Farmers Branch, University Park, Las Colinas, and Preston Hollow has demonstrated that regular maintenance significantly reduces the frequency and severity of AC repairs. We specialize in maintenance contracts that provide scheduled inspections and tune-ups designed to identify potential problems before they result in system failure. During these maintenance visits, our technicians clean condenser and evaporator coils, check and adjust refrigerant levels if needed, lubricate moving parts, tighten electrical connections, and calibrate thermostats for optimal performance. This proactive approach typically extends equipment life by several years while maintaining peak efficiency levels that keep energy costs manageable.

The economic benefits of preventive maintenance become particularly apparent when considering the typical repair costs associated with neglected systems. A dirty condenser coil, for instance, forces the compressor to work harder, potentially shortening its lifespan from an expected fifteen to twenty years down to just eight to ten years. Similarly, clogged air filters restrict airflow, causing evaporator coils to freeze and potentially damaging the compressor through liquid refrigerant flood-back. Our maintenance programs address these issues systematically, protecting your investment while ensuring reliable comfort throughout Irving’s challenging weather conditions.

Advanced Solutions and Technology Integration

As a certified Climate Master dealer and family-owned operation, we combine traditional values with cutting-edge technology to deliver superior AC repair services. Our technicians utilize digital manifold gauges that provide precise refrigerant pressure readings and calculate superheat and subcooling automatically, eliminating calculation errors and speeding diagnosis. We also employ thermal imaging cameras to identify hidden problems such as ductwork leaks, inadequate insulation, and electrical hot spots that might otherwise go undetected until they cause system failure.

Modern air conditioning systems increasingly incorporate sophisticated control boards and variable-speed components that require specialized knowledge for proper diagnosis and repair. Our ongoing training programs ensure our technicians stay current with these technological advances, whether working on traditional single-stage systems or advanced variable-refrigerant-flow equipment. We maintain relationships with multiple equipment manufacturers beyond our primary Carrier partnership, enabling us to service virtually any brand or model of air conditioning equipment found in Irving area homes and businesses. This comprehensive capability means you won’t need to search for brand-specific technicians when your system requires repair.

Our commitment to excellence extends beyond technical proficiency to encompass customer service and communication. We understand that AC repairs often represent unexpected expenses, so we provide detailed explanations of problems found, necessary repairs, and available options. Our technicians carry commonly needed parts in their service vehicles, allowing many repairs to be completed during the initial visit. When special-order parts are required, we leverage our established supplier relationships to minimize wait times, keeping your discomfort period as brief as possible while maintaining our high standards for repair quality and system reliability.
