AC INSTALLATION IN DIAMONDHEAD · WHY LOCALS CALL KEITH'S

Rheem Triple Diamond for 7 years running. Proper Manual-J sizing. Full-system installs finished in one day. That standard applies whether you're in Diamondhead Country Club area, West Diamondhead, or anywhere else in Diamondhead.

Diamondhead is a planned waterfront community with golf course and bayou-front homes. Housing stock skews higher-end, with larger multi-system installs common and premium efficiency upgrades frequently requested. Humidity load is high (sitting on Rotten Bayou and tidal estuaries) so dehumidification and zoned systems are more common here than in inland cities. Hurricane prep is a bigger deal too given exposure.

AC Installation in Diamondhead covers these ZIP codes: 39525. We service homes near Diamondhead Country Club, Lake Catherine, Rotten Bayou, and every neighborhood between.

DIAMONDHEAD AC INSTALLATION
QUESTIONS ANSWERED.

How do you decide what size system I need?

We run a Manual-J load calculation on your home: insulation, window count and orientation, ductwork condition, air infiltration, occupancy. Not square-footage guesswork. Oversized systems short-cycle and destroy comfort in Gulf humidity. Right-sized wins.

Why Rheem?

We've been a Rheem Triple Diamond Dealer for 7 years straight. Their warranties, parts availability, and coastal-corrosion coatings hold up on the Coast better than most. We install Lennox, Trane, Daikin, Mitsubishi mini splits, and Carrier too when the customer prefers.

What's included in the install price?

Equipment, install labor, all electrical and refrigerant line connections, condensate line, disposal of the old system, permit, city inspection scheduling, refrigerant charge, thermostat, commissioning, and a 10-year manufacturer parts warranty plus 1-year labor. No surprise fees.

How long does the install take?

Standard replacement: one day. Full system with new ductwork: two days. Mini split: half day to one day depending on zone count.

Do I need to be home?

For the initial hour and the walkthrough at the end, yes. The middle 4-6 hours our crew works independently. We're W-2 employees, background checked, uniformed, drug tested.
