Preventive maintenance is the best way to avoid unexpected breakdowns and keep your HVAC system running efficiently. AAD Heating & Air Conditioning offers comprehensive tune-up plans for both air conditioners and heating systems. Our seasonal maintenance includes cleaning coils, checking refrigerant levels, tightening electrical connections, lubricating moving parts, and testing all safety controls.

We recommend bi-annual tune-ups — once in spring for your AC and once in fall for your furnace or heat pump. Regular maintenance can reduce energy consumption by up to 15%, extend the life of your equipment, and catch small problems before they become expensive repairs. It also helps maintain manufacturer warranties, which often require proof of regular service.

Our maintenance customers receive priority scheduling, discounts on repairs, and a complete system report after each visit. We serve both residential and commercial clients in Houston. Invest in peace of mind with a professional HVAC tune-up from AAD today.
