Nelson and Ball Heating & Cooling: Expert HVAC Services Serving London, OH 43140

Common signs your ducts may need attention include visible dust blowing from vents, unexplained increases in household dust, musty odors when the system runs, or if you've recently completed a renovation. For London homes, regular duct cleaning can also help your HVAC system run more efficiently, which is important for managing those high energy bills we often see in our climate. Our team can perform an inspection to assess your specific situation.

This is a frequent issue we address for homeowners in the London area and often points to a problem with the reversing valve. This critical component directs refrigerant flow to change the system's mode. If it's stuck, failing, or has an electrical issue, your heat pump won't function correctly. Our technicians are experienced in diagnosing and repairing heat pump reversing valve problems to restore your system's proper operation and efficiency.

Our maintenance service is designed to keep your system running smoothly and catch small issues before they become big problems. A typical visit includes cleaning condenser and evaporator coils, checking refrigerant levels, inspecting electrical connections, testing system controls and safety devices, lubricating moving parts, and checking the blower motor and airflow. For plumbing, a separate inspection would focus on checking for leaks, testing water pressure, and ensuring drains are clear. This proactive care is key to system longevity and maintaining energy efficiency.
