Quality Air Conditioning Company in Riverside, CA

Very often, yes. Ducts running through a hot attic that leak at the joints lose conditioned air before it ever reaches the room, and the rooms at the end of the longest runs feel it first. Sealing them is usually cheaper than upsizing the equipment.

Sizing depends on square footage, insulation, ceiling height, window count and orientation, and how your ductwork is laid out. It is not something to guess at — an oversized unit short-cycles and leaves the air humid, and an undersized one never keeps up. We perform an in-home load calculation before recommending equipment.

The usual causes are a dirty air filter, a refrigerant leak, a failing capacitor or compressor, or a frozen evaporator coil. Start by checking the filter and the thermostat setting. If the system is still blowing warm air after that, it needs a technician — running it in that state can make the underlying problem worse.

It depends on the age of the system, what the repair costs, and how often it has needed attention. As a rule of thumb, a unit past 10 to 12 years that is failing repeatedly is usually better replaced than repaired again. Our technicians will give you both numbers and let you decide rather than pushing you toward a new system.

Most residential air conditioners last somewhere between 10 and 12 years. Systems here tend to work harder than they would in a milder climate because of how long our cooling season runs, so maintenance makes a real difference to how much of that range you actually get.

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.

We run seasonal promotions on repairs, installations and maintenance throughout the year. Our current offers are listed on our Specials page, and it is worth checking before you book so you are not leaving anything on the table.
