Air Conditioning Maintenance

We are sometimes asked, “Is an AC tune-up necessary?” Your cooling and heating system is a major investment for your home and your comfort. After years of experience, we strongly recommend having your air conditioning system inspected and preventative maintenance performed each season to keep your system running right year round.

Regular air conditioner maintenance can pay big dividends in improved system performance and reduced energy costs. It can also help to extend the life of your system parts and equipment, as well as help to prevent costly and inconvenient breakdowns.

What’s included in an AC tune-up? A complete Central One Service LLC tune-up includes all these services for one low price:

• Connect gauges and check operating pressures
• Record liquid line and suction line pressures
• Check for signs of refrigerant leaks
• Check all motor amperage draws
• Record temperature differential across evaporator coil
