If you are looking for HVAC service San Bernardino, CA homeowners trust, you are in the right place. San Bernardino County and the wider Inland Empire rely on Magnolia for expert heating and air conditioning repair, installation and maintenance.
San Bernardino sees some of the hardest summer heat anywhere we work, and a lot of its housing was built long before anyone designed a home around central air. Systems here run longer and harder than the same equipment would a few miles west. What we usually find is not a broken air conditioner but a system fighting the house — undersized or leaking ducts in an unconditioned attic, insulation that has flattened over decades, and returns too small for the tonnage someone installed later.
We offer same-day service where the schedule allows, and every repair carries our 12-month guarantee.

Once a year, ideally in spring before the Inland Empire heat arrives. An annual tune-up catches small problems while they are still small, keeps the system running efficiently through the hottest months, and is usually required to keep manufacturer warranties valid.
Once a year, ideally in early fall before you need it. An annual tune-up keeps the system running efficiently, catches safety issues such as cracked heat exchangers or venting problems, and helps avoid the failure that always seems to happen on the first cold night.
Start with an assessment rather than a product. We look at your filtration, ductwork, attic insulation and water supply together, because the right first move is different in every home — sometimes it is a better filter, sometimes it is sealing the ducts, and sometimes it is the water coming into the house.
