One Hour Heating & Air Conditioning: Certified HVAC Services Serving Southfield, MI 48033

Our maintenance service is designed to keep your system running smoothly and efficiently. We perform a comprehensive check that includes inspecting electrical connections, cleaning critical components like the evaporator and condenser coils, checking refrigerant levels, and testing system controls. For Southfield residents, we pay special attention to the condenser coil, which can get dirty and reduce efficiency. Regular maintenance helps prevent common local issues and can extend the life of your HVAC equipment.

Refrigerant leaks are a frequent issue in Southfield due to system age and seasonal strain. When you call us, our certified technicians first perform a detailed leak detection test using specialized tools to locate the source. We repair the leak according to manufacturer specifications and then recharge the system with the precise amount of refrigerant required. We never simply 'top off' a leaking system, as that doesn't solve the problem and is against EPA regulations. Properly fixing the leak restores cooling performance and efficiency.

As the largest HVAC service provider, we offer honest assessments to help you decide. Generally, replacement becomes a practical consideration if your system is over 10-15 years old, requires frequent and costly repairs, or struggles to maintain comfort despite maintenance. We also evaluate if your energy bills are rising significantly due to declining efficiency. For Southfield homeowners, we factor in the local climate's demands on your system. We'll explain all options, so you can make an informed decision that fits your home and budget.
