Top 5 HVAC Contractors for HVAC System Maintenance in San Antonio, Texas

Your HVAC system should be professionally serviced twice a year. The air conditioning system should be tuned up in the spring to prepare for summer, and the heating system should be serviced in the fall to prepare for winter. This schedule ensures both components are operating safely and efficiently before their peak usage seasons.

You should call for immediate service if you notice loud or unusual noises, weak airflow from the vents, strange odors, or if the system cycles on and off too frequently. Other warning signs include the system not providing adequate heating or cooling, or a sudden, unexplained increase in your energy bills, as these often point to an underlying problem.

A professional tune-up involves a thorough cleaning, inspection, and adjustment of the system. Key tasks include cleaning indoor and outdoor coils, checking refrigerant levels, tightening electrical connections, lubricating moving parts, testing safety controls, and verifying thermostat accuracy. The checklist is tailored to either the heating or cooling system depending on the season.

Regular maintenance is important because it improves energy efficiency, extends the lifespan of your equipment, and prevents costly, unexpected breakdowns. A clean and properly adjusted system uses less energy, which lowers utility bills. Furthermore, preventative service allows technicians to fix minor issues before they escalate into major repairs, ensuring reliability.

A clogged filter restricts airflow, which significantly reduces your HVAC system's efficiency and increases your energy bills. This strain can lead to costly component damage and premature system failure. A dirty filter also fails to properly capture contaminants, leading to poorer indoor air quality and a buildup of dust within your ductwork.
