Replacing or performing a High-Efficiency Tuneup for your Air Conditioning Unit can deliver savings throughout the year.

A traditional home comfort system has two parts: an indoor unit, such as a furnace or air handler, and an outdoor unit. The condenser is the outdoor unit that uses a compressor to pump refrigerant to the indoor evaporator to produce the cooling effect. Indoor and outdoor units are designed to work together. When the air conditioner is properly matched with a furnace or air handler, you get maximum efficiency and longer system life.

While we repair, tune and service all makes and models of Air Conditioning units in San Diego, we proudly provide York and Daikin for new equipment installations.

Money Saving Cooling Tip!

Changing your furnace filter in the springtime before operating your air conditioner will reduce your energy costs, and keeps your equipment running smoothly all summer long. Remember to cut back any shrubbery, and keep other debris at least 24 inches from your outdoor unit.

A precision air conditioning tune-up pays for itself through the energy savings alone.
