Understanding AC Repair Needs in Addison’s Climate

When your air conditioning system fails during an Addison summer, where temperatures regularly soar above 100 degrees Fahrenheit, you need immediate professional assistance. At M.B. Kiser Heating and Air Conditioning Co. Inc., we’ve been responding to these urgent calls since 1945, making us the oldest AC company in Dallas and the surrounding areas. Our extensive experience in the North Texas climate means we understand exactly how the extreme heat, humidity fluctuations, and occasional severe weather impact your cooling system’s performance and longevity.

The unique weather patterns in Addison create specific challenges for air conditioning systems. The combination of intense summer heat, spring allergens, and occasional winter freezes puts extraordinary stress on AC components. Your system works overtime from May through September, often running continuously during peak summer months. This constant operation accelerates wear on compressors, fan motors, capacitors, and electrical connections. Additionally, the high humidity levels common in North Texas can lead to frozen evaporator coils, drainage problems, and increased strain on dehumidification processes within your system.

Common AC Problems We Repair in Addison Homes

Through decades of service as the oldest Carrier Dealer in Dallas, we’ve identified patterns in air conditioning failures specific to Addison residences. Refrigerant leaks represent one of the most frequent issues we encounter, often manifesting as reduced cooling capacity, ice formation on the indoor unit, or hissing sounds near the refrigerant lines. These leaks typically develop at connection points, valve cores, or through microscopic holes in aging copper tubing. Our EPA-certified technicians use advanced leak detection equipment including electronic sniffers and UV dye systems to pinpoint exact leak locations, ensuring complete repairs rather than temporary fixes.

Electrical component failures account for approximately 40% of our service calls in Addison. Capacitors, which provide the initial power surge needed to start motors, frequently fail due to voltage fluctuations and heat exposure. Contactors, the switches that control power flow to your compressor and fan motors, wear out from repeated cycling and can cause intermittent cooling problems. We also regularly replace failed circuit boards, thermostats with faulty sensors, and damaged wiring compromised by rodents or weather exposure. Our 24/7 availability means we respond immediately when these critical components fail, with our call center forwarding after-hours emergencies to our on-call technician and service manager.

Compressor problems require particular expertise to diagnose and repair correctly. As a family owned and operated company certified with Climate Master, we’ve developed specialized diagnostic procedures for identifying compressor issues before complete failure occurs. Warning signs include unusual noises like grinding or squealing, hard starting, frequent breaker trips, and elevated amp draws during operation. We perform comprehensive electrical testing, measure superheat and subcooling values, and analyze oil samples when necessary to determine whether repair or replacement offers the best value.

Our Comprehensive Repair Process

When you contact M.B. Kiser Heating and Air Conditioning Co. Inc. for AC repair in Addison, our systematic approach ensures accurate diagnosis and lasting solutions. Our technicians begin with a detailed system inspection, checking all major components including the outdoor condenser unit, indoor evaporator coil, air handler, ductwork connections, and control systems. We measure temperature differentials across the evaporator coil, test capacitor microfarad ratings, check refrigerant pressures and temperatures, inspect electrical connections for signs of overheating, and evaluate airflow rates throughout your system.

Following diagnosis, we provide detailed explanations of identified problems, discussing repair options, costs, and expected outcomes. Our transparent pricing structure includes itemized estimates for parts and labor, with no hidden fees or surprise charges. We maintain extensive parts inventory for most major brands, though our specialization as a Carrier dealer means we have immediate access to genuine Carrier components. For residential and light commercial customers in Addison, we often complete repairs during the initial service visit, minimizing downtime and discomfort.

Preventive Maintenance and Service Contracts

Our concentration on maintenance contracts reflects our understanding that prevention costs far less than emergency repairs. Regular maintenance visits include comprehensive system tune-ups designed to identify potential problems before they cause system failures. During these visits, we perform the following essential services:

• Clean and inspect evaporator and condenser coils removing dirt and debris that reduces efficiency
• Check and adjust refrigerant levels ensuring optimal cooling performance
• Lubricate all moving parts reducing friction and extending component life
• Test and calibrate thermostats maintaining accurate temperature control
• Inspect and tighten electrical connections preventing failures from loose or corroded terminals
• Replace air filters improving air quality and system efficiency
• Clear condensate drains preventing water damage and biological growth

These maintenance procedures typically extend system life by 30-40% while reducing energy consumption by up to 25%. For Addison customers, where cooling costs represent significant utility expenses, these savings quickly offset maintenance investment costs.

Emergency Response and After-Hours Service

Equipment failures don’t follow business hours, which is why we maintain 24/7 emergency service availability. Our after-hours call center ensures you always reach a real person who understands HVAC emergencies. They immediately forward urgent calls to our on-call technician and service manager, who assess the situation and dispatch appropriate resources. For non-emergency issues called in after hours, we prioritize these calls and contact customers first thing in the morning to schedule prompt service appointments.

This commitment to availability proves especially valuable during Addison’s extreme weather events. When heat waves strike and AC systems across the area fail simultaneously, our established customers with maintenance contracts receive priority service. Our fleet of fully stocked service vehicles allows technicians to complete most repairs without parts delays, restoring comfort quickly even during peak demand periods.

Installation Services for Irreparable Systems

Sometimes, repair isn’t the most economical option. Systems over 15 years old, those requiring frequent repairs, or units using obsolete R-22 refrigerant often warrant replacement. As expressed in our motto, “It’s Wiser to Have Kiser Install Carrier,” we specialize in complete system installations. Our installation process includes load calculations to ensure proper sizing, ductwork evaluation and modification when necessary, proper refrigerant charging using superheat and subcooling methods, and comprehensive system commissioning to verify optimal performance.

Modern high-efficiency systems offer substantial improvements over older equipment. SEER ratings now reach 21 or higher, compared to 10 SEER units common in older Addison homes. Variable-speed technology provides better humidity control and more consistent temperatures while reducing energy consumption. Smart thermostats enable remote monitoring and control, optimizing comfort and efficiency. We help customers navigate available rebates and financing options, making upgrades more affordable while delivering immediate energy savings and enhanced comfort throughout their homes.
