Routine maintenance is the secret to a long-lasting, efficient HVAC system. Hay Cool HVAC offers comprehensive maintenance plans designed to catch small issues before they become costly emergencies. Our maintenance services are ideal for homeowners, property managers, and businesses in California who want to protect their investment and ensure year-round comfort.

During a typical maintenance visit, our technicians perform a 20+ point inspection. We check refrigerant levels, tighten electrical connections, lubricate moving parts, clean coils and blowers, test thermostat accuracy, inspect safety controls, and replace standard air filters. For heating systems, we examine heat exchangers for cracks and test carbon monoxide levels. For AC units, we measure temperature drop and check drain lines for clogs. We also provide a detailed report with photos and recommendations. By enrolling in our seasonal tune-up program, you gain priority scheduling, discounted repair rates, and extended equipment life. Filter replacement is included for optimal air quality and system efficiency. We also offer indoor air quality solutions, such as humidifier and purifier checks, to keep your environment healthy.
