Who We Are
Meet our team →
Southern California's climate demands a HVAC company that actually understands it.
Founded in 2007 by two local technicians tired of seeing homeowners overcharged for shoddy work, Tidewater Air has grown into one of the most trusted HVAC companies on the Westside. We know the difference between a coastal home in Redondo Beach and a hillside property in Bel Air — and we size, spec, and install accordingly.
Every estimate is honest. Every job comes with written documentation. Every technician carries full certification and treats your home like their own. That's been our standard since day one, and it hasn't changed.

What We Do
Full-range HVAC services, residential & commercial.
From emergency repairs in July to full system replacements in new construction, Tidewater Air handles every aspect of your indoor climate.
Heating Systems
Gas furnaces, heat pumps, and radiant heat for LA's cooler months. We recommend what makes sense for your utility rates and comfort goals — not what has the best margin for us.
Emergency Repair
Compressor failures, refrigerant leaks, electrical faults, frozen coils — our technicians are dispatched around the clock. Most calls arrive on-site within 90 minutes, guaranteed.
Duct Cleaning & Sealing
Leaky or contaminated ductwork silently raises your energy bills and degrades air quality. We inspect, clean, and seal your duct system — measurable improvement, documented before and after.
Annual Maintenance Plans
Two tune-up visits per year, priority scheduling, and a 15% discount on any repair parts — for one fixed monthly rate. The plan typically pays for itself before the first LA heat wave.
Smart Thermostat & Controls
Upgrade to zone-based control and remote scheduling. We install, configure, and integrate with your home's wiring — not a tutorial you watch on your own afterwards.
Why Tidewater Air
We do the work most contractors skip.
A properly installed HVAC system runs quieter, lasts longer, and costs less to operate. Getting there requires steps that many contractors rush past — Manual J load calculations, static pressure measurements, refrigerant charge verification. We don't skip them. Your comfort and your utility bill will tell the difference within the first season.
Request a free consultationManual J Load Calculation
We calculate the exact cooling and heating load for your specific structure before recommending any equipment. No rule-of-thumb guesses.
Static Pressure Testing
We test your duct system before and after every installation. Undersized or leaky ducts account for up to 30% of wasted cooling in LA homes.
Written Commissioning Report
Every installation ships with a full commissioning document: airflow readings, refrigerant charge, electrical draw, and system photos. You keep it forever.
No-Surprise Scheduling
You'll receive a two-hour arrival window and a text when your technician is 30 minutes away. No four-hour "sometime before noon" windows.

What Homeowners Say
Trusted by over 4,200 households across LA.
"Our old unit died mid-August during a heat wave. Tidewater had someone here same afternoon, diagnosed the issue in 20 minutes, and had the part the next morning. No runaround, no inflated emergency fee."
"We replaced the whole system in a 1960s house with original ductwork. Marcus walked us through three options at different price points without pushing us toward the most expensive. The install was clean, fast, and they even patched the drywall access panel themselves."
"I manage four commercial properties in El Segundo. Tidewater handles all of them on an annual contract. Response time is consistent, the technicians know our buildings, and I've never had to call them back for the same issue twice."
Homeowner Guidance
Practical advice — no filler, no upsell.
Short reads from our technicians on things LA homeowners actually ask about.
Maintenance
How often should you actually change your air filter in an LA home?
The standard answer is every 90 days. Here's why coastal homes — especially near the beach — need a different schedule.
Energy
Why your AC runs constantly even when it's only 78°F outside
Three common culprits: undersized equipment, duct leaks, and poor attic insulation. We explain how to diagnose each without calling a technician first.
Heat Pumps
Heat pumps in Southern California: do they actually make sense?
A clear-headed look at efficiency gains, installation costs, and where the rebates actually apply — for the LA climate specifically, not the national average.
