What size air conditioning unit do I need?

The size of the air conditioning unit you need depends on several factors, including the square footage of your home, insulation quality, and local climate. Our technicians will conduct a thorough assessment to determine the right size for you.

Will I need to replace my ductwork?

Not necessarily. If your existing ductwork is in good condition and properly sized, it can often be reused. However, if it is damaged or inadequate, we may recommend upgrades to ensure optimal performance.

What are the signs that I need a new AC unit?

Signs that you may need a new AC unit include frequent repairs, rising energy bills, inconsistent cooling, and the unit being over 10-15 years old. Our technicians can provide an assessment to help you decide.

Do you offer warranties on your installations?

Yes, we offer warranties on our installations and the equipment we use. This provides you with added peace of mind regarding the longevity and performance of your new system.

AC Installation Across South Bay Los Angeles

Professional air conditioning installation and replacement. Energy-efficient systems sized right for your home. Our ac installation service covers the entire South Bay corridor — from the coastal cities (Torrance, Redondo Beach, Hermosa Beach, Manhattan Beach, El Segundo) through the inland communities (Hawthorne, Gardena, Carson, Long Beach) and the Palos Verdes peninsula. Average response time across all of these is 45 Minutes, and we never add overtime charges for nights, weekends, or holidays.

If you're searching for ac installation, you're probably already dealing with one or more of these symptoms: AC over 15 years old, Frequent repairs needed, High energy bills, Uneven cooling, AC running constantly. Each of those points to a specific category of failure, and the right diagnostic path starts with measuring before guessing — that's the difference between a same-day fix and a return visit.

Pricing & What's Actually Included

Typical ac installation pricing runs $5,400–$11,800 for standard scope. Our $89 diagnostic fee is waived with repair — meaning if we do the work, you don't pay the diagnostic on top. We provide a detailed written quote before any work begins, broken down by part, labor, and any optional upgrades. There are no "trip charges," no "fuel surcharges," and no hidden line items.

What's included in the $89 diagnostic: a full system inspection, electrical testing (capacitor microfarad reading, contactor pitting check, motor amp draw), refrigerant pressure readings (for cooling work), combustion analysis (for gas heating work), static-pressure measurement on the ductwork, and a written report with the readings. If the issue is non-obvious, we run a thorough enough diagnostic that we won't have to come back for the same problem.

Common Failure Modes We See

Across the South Bay we run roughly 5K+ ac installation jobs per year, which gives us pattern recognition that one-off shops don't have. The same five or six failure modes account for the vast majority of calls.

AC over 15 years old
Frequent repairs needed
High energy bills
Uneven cooling
AC running constantly
Home addition needs cooling

Our Service Process

We've refined this process over 15+ years of field work in South Bay. The goal is to fix the issue on the first visit when at all possible, and to never charge for parts you don't actually need.

What to Expect from Our Technicians

Every technician dispatched for ac installation is NATE-certified (industry gold standard for HVAC competency), EPA Section 608 Universal certified (federally required for refrigerant work), and has at least 5 years of residential or light-commercial field experience. We background-check every team member, drug-test annually, and require continuing-education hours each year on new equipment from Carrier, Trane, Lennox, Goodman, Rheem, Daikin, and the rest of the major brands.

Trucks are GPS-tracked so dispatch can give you a real-time ETA, not a four-hour window. Each truck carries the most common parts for ac installation work — capacitors, contactors, hot-surface ignitors, flame sensors, common condensate float switches, and a stocked refrigerant kit — so most repairs happen in a single visit.

“Old Goodman from 2003 finally died. Replaced with an American Standard Platinum 18 (matched evaporator coil + air handler). Crew was meticulous — vacuumed to 350 microns, weighed in the charge, did a static-pressure test post-install (came in at 0.38 in. wc, well within spec). Also fixed a duct collapse they noticed in the attic for free. Five-star work all the way.”
