HVAC Services Florissant MO | Call Patrico J Heating & Cooling Company

Uneven temperatures are often a sign of improper HVAC sizing, a common issue in our area. If your system is too large, it short-cycles, wasting energy and not dehumidifying properly. If it's too small, it runs constantly without reaching the desired temperature. Our experts perform detailed Manual J load calculations to ensure your new system or replacement is perfectly sized for your home's layout, insulation, and local climate, providing consistent comfort and efficiency.

Warning signs include strange noises (screeching, grinding), weak airflow from your vents, the system not starting, or the motor overheating and shutting off. A failing blower motor is a critical repair, as it stops your entire heating or cooling system. For Florissant residents, we offer prompt emergency service. Our technicians carry common motor parts and can often diagnose and complete this repair in a single visit to restore your comfort quickly.

Our intense summers and cold winters put significant strain on HVAC systems. Our comprehensive maintenance service includes cleaning critical components, checking electrical connections, lubricating motors, and testing safety controls. This proactive care helps prevent blower motor failures by ensuring proper operation, catches minor issues before they become major repairs, and keeps your system running at peak efficiency year-round, saving you money on energy bills and unexpected breakdowns.
