Our Air Conditioner Repair Services Include:

• Fast & Accurate AC Diagnostics: Quick and precise AC diagnostics help identify issues before they escalate. Our expert technicians use advanced tools to detect and resolve problems efficiently, saving time and money. Whether it’s airflow restrictions, refrigerant leaks, or electrical failures, our diagnostic services ensure your system operates reliably and efficiently all season long.
• Refrigerant Leak Detection & Repair: Low refrigerant levels can reduce cooling performance and increase energy consumption. Our specialists quickly identify leaks, seal them, and recharge your system to maintain efficiency. Ensuring proper refrigerant levels prevents compressor damage, restores cooling power, and keeps your air conditioner running at peak performance without unnecessary energy waste.
• Compressor & Fan Motor Repairs: The compressor and fan motor are essential components that regulate airflow and cooling efficiency. If they fail, your AC may struggle to maintain temperature control. Our technicians diagnose issues, repair or replace faulty parts, and restore your unit’s ability to provide consistent cooling without excessive strain or energy consumption.
• Thermostat & Sensor Repairs: A malfunctioning thermostat or sensor can cause uneven cooling, higher energy bills, or complete system failure. Our experts troubleshoot, recalibrate, or replace faulty components to ensure precise temperature regulation. Accurate thermostat performance enhances comfort, efficiency, and overall system reliability, preventing unnecessary wear and tear on your AC unit.
• Electrical Component Troubleshooting: Faulty electrical components, such as fuses, relays, and wiring, can disrupt AC functionality. Our certified technicians inspect and repair electrical issues to restore safe, efficient operation. Proper troubleshooting prevents power failures, short circuits, and overheating, ensuring your air conditioning system operates dependably without posing any safety hazards.
• Evaporator & Condenser Coil Repairs: Dirty or damaged coils reduce cooling efficiency and force your AC to work harder, increasing energy costs. Our coil repair services restore performance by cleaning, repairing, or replacing evaporator and condenser coils. This improves heat exchange, enhances efficiency, and extends the lifespan of your air conditioning unit.
• Ductwork Inspection & Repair: Leaky or blocked ducts can reduce airflow and strain your AC, leading to inconsistent temperatures and higher energy bills. Our technicians inspect, seal, and repair ductwork to improve efficiency, airflow, and indoor comfort. Properly maintained ducts ensure that cooled air reaches every room effectively, optimizing your system’s performance.

We service all major AC brands, not just Bryant! Whether you have a central air system, ductless mini-split, or heat pump, we have the expertise to handle it all. If you AC is beyond repair, we also provide AC replacement service.

How to Prevent Costly Repairs

An air conditioning breakdown often happens when you least expect it, leading to expensive repairs or even premature replacement. However, with regular maintenance and simple preventive steps, you can avoid unexpected AC failures and keep your system running efficiently year-round.

• Schedule Regular AC Tune-Ups: Routine AC maintenance prevents unexpected breakdowns and costly repairs. Professional tune-ups include cleaning coils, checking refrigerant levels, and inspecting components for early issue detection. Stewart Heating Plumbing Air Conditioning provides comprehensive maintenance plans to enhance system performance, extend lifespan, and keep your home comfortably cool year-round.
• Change Your Air Filters Regularly: Dirty air filters restrict airflow, forcing your AC to work harder, increasing energy bills, and leading to system malfunctions. Replacing filters every 1-3 months improves indoor air quality, enhances efficiency, and prolongs unit lifespan. Regular filter changes ensure consistent cooling while reducing unnecessary strain on your air conditioning system.
• Keep the Outdoor Unit Clean: The outdoor AC condenser unit collects dirt, leaves, and debris, obstructing airflow and decreasing cooling efficiency. Regular cleaning prevents blockages, ensures optimal ventilation, and enhances system performance. Keeping the unit clear of obstructions allows your AC to function efficiently, reducing energy costs and preventing overheating or mechanical failures.
• Watch for Warning Signs: Ignoring small issues can lead to major repairs. Be proactive and contact a professional if you notice:
