Experienced HVAC Services in Sherman, TX 75090 - Markl & Sons Cooling & Heating

Our routine maintenance service is designed to prevent costly breakdowns and extend the life of your system. For Sherman homeowners, this includes a thorough inspection and cleaning of key components, checking refrigerant levels, testing system controls, and importantly, inspecting ductwork for leaks and checking the blower motor—two common local issues that can hurt efficiency. This proactive approach helps ensure your system runs reliably through our hot summers and cool winters.

When a blower motor fails, it can stop your HVAC system from heating or cooling your home. Our certified technicians will first test the motor and its capacitor to diagnose the exact issue. For Sherman residents, we often find that dust accumulation or worn bearings are the cause. We'll provide a clear explanation of the problem and your repair options. If a replacement is needed, we install a quality motor that matches your system's specifications to restore proper airflow and comfort efficiently.

Our installation process begins with a detailed assessment of your Sherman home's layout, insulation, and your family's comfort needs. We'll help you select a properly sized and efficient system. Our experienced team handles the entire replacement, including careful removal of the old unit, precise installation of the new system, and a thorough check of the ductwork for any leaks that could reduce efficiency. We ensure everything is working perfectly before we leave, and we explain your new system's operation and warranty.
