AC Installation and Replacement in San Diego

A replacement takes out a system that is failing or worn and puts in a new one. A new installation brings air conditioning to a building, or part of a building, that has none. Both start with the same questions about the space.

Sizing comes from the building

Not from a rule of thumb about floor area. Insulation, window area and orientation, ceiling height and how the air is distributed all change the answer. Oversizing is a failure mode rather than a safety margin, because a system that cools the space quickly and shuts off never does much about humidity.

Ducted or ductless

Where ductwork already exists and suits the new system, a ducted system can use it, and ductwork modifications are on our list for when the layout needs changing. Where there are no ducts, or there is a room the ducts never reached, a mini split cools without them.

Signs it is time to replace

• Repairs that keep coming back on the same system.
• A major component failing on an older system.
• Rooms that never catch up, even after repairs.
• A building that has changed: an addition, a conversion, or a new use for the space.

What installation involves

Removing the old equipment, setting the new indoor and outdoor units, connecting the refrigerant lines, the electrical supply and the condensate drain, and confirming the system runs as it should. A new system can also need its own circuit or more panel capacity, and panel upgrades are on our electrical list, in house under the same CSLB license.

What to expect

• Call or send the form. Say what is there now, if anything, and which rooms need cooling.
• Estimate by phone. Air conditioning is usually estimated by phone.
• The work. Removal of the old system where there is one, then the new installation.
