Are you looking for a reliable air conditioning (AC), heating company in Irvine ?

Living in Irvine, you know how much you rely on your air conditioning, heating and ventilation system. That’s why we developed our unique maintenance process.

Why Is It Important to Maintain My Air Conditioner And Furnace?

If you could see an accident before it happened, wouldn’t you want to prevent it? Well, you can do just that. Proper maintenance can prevent trouble with your system before it becomes serious or even worse an emergency 


A routine heating and air conditioning maintenance will help prolong the life of your system. Maintaining your system will insure proper operation, and maintain its cleanliness. Dirt build up can lead to equipment malfunctioning. In addition, cleanliness will provide improved capacity and lower energy costs. Keep in mind, a regular maintenance will support your effort in meeting the manufacturer warranty requirements. 

Sit back, relax and leave the heating and air conditioning maintenance to us.

Maintenance Tips?

  • Dirty filters will cause your equipment heating and air conditioning  work harder than it should. This results in energy waste and even possible internal damage to the unit. Become familiar with the type of filter your system requires. If you have a washable filter that is reusable, make sure it is completely dry before replacing.

  • Periodically, place your thermostat on HEAT and move the temperature setting above room temperature. Listen for any unusual sounds. Contact us if you believe there may be a potential problem.

  • All of the return registers/ grilles should be kept free of obstructions such as furniture, dirt and debris. This will hinder proper air flow.

  • Improving indoor air quality starts with cleaning your humidifier reservoir regularly. Cleanliness of your humidifier will prevent build up of mold and mildew.

  • Unrestricted air flow to the outdoor unit is extremely important. Remove trash leaves, grass and tree trimmings that are in close proximity. Any debris that collect around the unit will cause your unit to work harder than intended, resulting in more energy use and higher utility bills.

  • A heat pump or air conditioner should sit level. If you notice a shifting or settling of the ground in which your unit sits, re-level. Moisture/water must drain properly from the condensing unit.


As part of this comprehensive air conditioning and heating system tune up process, we:

  • Inspect the air handler and coil 

  • Wash the condenser coil

  • Check the drain lines and pan

  • Provide a new air filter

  • Check the electrical connections to make sure none of the wires are burnt or frayed

  • Inspect the voltage and amperage on the motors and air conditioning compressor

  • Check for proper air flow

  • Examine the starting parts

  • Balance and calibrate the thermostat

  • Check the pressures and level of refrigerant
