A/C & Heating Maintenance

Tune-Up Services to Keep Your System at Its Best

On average, A/C and heating systems run about 3,300 hours per year in the Phoenix area, which means routine maintenance is required to maintain efficiency, dependency, and safety to prolong the operational lifespan of your system. Maintenance helps reduce preventable damage to the major components in your system. Since much of an HVAC system is interconnected, components can endure secondary damage when a nearby component fails. With regular maintenance, you can ensure that all components are in good working order, and none are causing stress for others. Regular HVAC maintenance and care also reduces the chance of a costly and inconvenient breakdown, keeps utility bills optimal, finds opportunities for greater home efficiency, and most importantly, provides reliable comfort for you and your family.

Our 34-Point Maintenance Clean & Check

Our maintenance clean and checks are the complete solution to combat efficiency and dependability deterioration, for summer or winter.  The Arizona climate is tough on HVAC systems.
