Central Air Systems Sized and Installed Correctly
Fresno asks more of an air conditioner than almost anywhere in California — months of triple-digit afternoons with barely a break overnight. A&G Heating & Air handles air conditioning installation in Fresno with a Manual J load calculation on every job, because a system sized by guesswork will not survive that duty cycle.
An oversized air conditioner short-cycles: it cools the thermostat quickly, shuts off, and leaves the house humid while the compressor wears out years early. That failure mode is common in Fresno because contractors match whatever was there before instead of calculating. We size on square footage, insulation, window orientation and duct condition, then design the duct system with Manual D so the capacity actually reaches the rooms.

Fresno's housing runs from 1950s Tower District bungalows to newer construction in the northwest, and the right installation approach differs sharply between them. Older homes often have undersized or leaky ductwork that will strangle a new high-efficiency system if it is left alone.
We evaluate the duct system as part of the quote rather than treating it as an upsell discovered later. Where the ducts can carry the design airflow, we say so. Where they cannot, we tell you what it takes to make the new system perform as rated.

We install Trane, Carrier, Lennox, Rheem, Bosch, Bryant, American Standard and Goodman. Because we are not tied to a single brand, the recommendation follows your home and budget rather than a quota.
High-efficiency options run 17 to 22 SEER2, which matters in Fresno where the cooling season is long enough for the efficiency difference to show up on real bills. Every installation is permitted under CA Title 24 and we handle the paperwork.
New installations carry a 10-year parts and labor warranty, and 0% APR financing is available. Once the system is in, seasonal maintenance is what keeps it at rated efficiency through Fresno summers — see our AC maintenance and air conditioning services pages for what that involves.
