T & H Mechanical Systems - Fairfield's Licensed HVAC Services

Yes, poor cooling is a common sign of a refrigerant leak, especially during our Fairfield summers when systems run hard. Refrigerant is the lifeblood of your AC; low levels force the system to overwork, leading to higher bills and potential failure. If you notice weak airflow, ice on the coils, or hissing sounds, turn the system off to prevent further damage and contact us. Our technicians use specialized tools to locate and seal the leak, then recharge the system to the manufacturer's exact specifications, ensuring efficient and effective cooling.

In Fairfield's cold snaps, HVAC pipes can freeze due to inadequate insulation, a malfunctioning furnace, or blocked airflow. This is a serious issue that can lead to burst pipes and water damage. If you suspect frozen pipes, first check your furnace filter and ensure vents are open. Then, call us immediately. Our team will safely thaw the pipes, diagnose the root cause—whether it's a heating issue or poor insulation—and make the necessary repairs to restore heat and prevent future freezing.

Preventive maintenance is key to avoiding the most common local HVAC issues. We recommend a professional tune-up for your AC in the spring and your heating system in the fall. This allows us to check refrigerant levels, inspect pipes and insulation, clean components, and catch small problems before they turn into major repairs like leaks or freezes. As your local HVAC partner, we can create a customized maintenance plan to keep your system running efficiently, extend its lifespan, and protect your Fairfield home's comfort through every season.
