Understanding Heating System Failures in Irving’s Climate

When your heating system breaks down during a cold North Texas winter night, you need reliable repair services immediately. At M.B. Kiser Heating and Air Conditioning Co. Inc., we’ve been responding to heating emergencies in Irving since 1945, making us the oldest Carrier dealer in Dallas. Our extensive experience means we’ve encountered virtually every type of heating problem that can occur in residential and light commercial properties throughout the area.

Irving’s unique weather patterns, with sudden temperature drops and occasional ice storms, put significant strain on heating systems. The rapid temperature fluctuations common in North Texas can cause components to expand and contract repeatedly, leading to premature wear and unexpected failures. Our technicians understand these regional challenges and arrive prepared with the tools and parts necessary to address the most common heating issues affecting Irving homes and businesses.

Common Heating Problems We Repair

Heat exchanger failures represent one of the most serious issues we encounter in Irving heating systems. These critical components transfer heat from the combustion process to the air circulating through your home. When a heat exchanger develops cracks or corrosion, it can release dangerous carbon monoxide into your living space. Our certified technicians use advanced diagnostic equipment to detect even hairline cracks that might otherwise go unnoticed during routine inspections.

Ignition system malfunctions account for approximately 40% of our heating repair calls during winter months. Modern furnaces use either electronic ignition systems or pilot lights to initiate the heating process. Electronic ignitors can fail due to electrical surges, wear, or contamination from dust and debris. We stock replacement ignitors for all major brands and can typically complete these repairs within an hour of arrival. For older systems with pilot lights, we address issues ranging from thermocouple failures to gas pressure problems that prevent reliable ignition.

Our 24/7 Emergency Response System

Heating emergencies don’t follow business hours, which is why we maintain a comprehensive after-hours response system. Our dedicated call center operates around the clock, ensuring that when you call with a heating emergency, a real person answers your call immediately. The call center staff collects essential information about your heating problem and forwards it directly to our on-call technician and service manager.

This two-tier notification system ensures the fastest possible response to your heating emergency. While our on-call technician prepares to dispatch to your location, the service manager reviews your service history and can provide additional guidance if needed. If your situation requires scheduling rather than immediate emergency service, we follow up first thing in the morning to arrange a convenient appointment time. This systematic approach has earned us a reputation for reliability throughout Irving, Farmers Branch, Las Colinas, and surrounding communities.

Diagnostic Process and Repair Techniques

Our heating repair process begins with a comprehensive system evaluation. We examine key components including:

• Blower motor and capacitor – checking for proper operation and electrical draw
• Gas valve and pressure switches – ensuring safe and efficient fuel delivery
• Control board and wiring – verifying all electrical connections and circuit board functionality

Advanced diagnostic tools allow us to pinpoint problems quickly and accurately. We use combustion analyzers to measure carbon monoxide levels and ensure proper fuel-to-air ratios. Digital multimeters help us identify electrical issues, while manometers verify correct gas pressure throughout the system. This technical approach eliminates guesswork and ensures we address the root cause of heating problems rather than just treating symptoms.

Preventive Maintenance and Long-term Solutions

Regular maintenance contracts represent one of our core service offerings, helping Irving residents avoid unexpected heating failures. Our maintenance programs include thorough annual inspections, cleaning of critical components, and replacement of wear items before they fail. Statistical data from our service records shows that customers with maintenance contracts experience 75% fewer emergency repairs compared to those who only call when problems arise.

During maintenance visits, we clean burner assemblies to ensure efficient combustion, lubricate moving parts to reduce friction and wear, and test all safety devices to verify proper operation. We also check and adjust gas pressure, inspect venting systems for blockages or corrosion, and measure temperature rise across the heat exchanger. These proactive measures extend equipment life and maintain peak efficiency, reducing both repair costs and energy consumption.

Installation and Replacement Considerations

When repairs become frequent or costly, replacement might be the most economical solution. As a certified Climate Master dealer and the oldest AC company in Dallas, we offer expert guidance on selecting appropriate replacement systems. Modern high-efficiency furnaces can reduce heating costs by 30-40% compared to units installed 20 years ago, often paying for themselves through energy savings within five to seven years.

We specialize in installations for residential and light commercial customers throughout Irving, University Park, Preston Hollow, and Dallas. Our installation process includes proper sizing calculations based on your building’s specific heat loss characteristics, ensuring optimal comfort and efficiency. We also handle all necessary permits and inspections, guaranteeing your new heating system meets current building codes and manufacturer specifications.
