Owner-operated

Ramiro answers the phone, quotes the job, and stands behind the work. No sales reps, no upsell games.

Affordable pricing

No storefront rent, no franchise fees, no bloated office. Every dollar goes into parts, trucks, and your fix — so my quotes come in lower.

20+ years hands-on

Two decades on Valley rooftops and in attics. If it runs on refrigerant or moves air, I've fixed it before.

Emergency repairs

Extended hours during heat waves and Saturday runs — if the heat is unbearable, I roll a truck the same day.

Summer-ready service

FAST, HONEST HVAC. BEATING THE VALLEY HEAT SINCE 2005

01

Cooling Repairs & Tune-Ups

Same-day fixes for weak cooling, refrigerant leaks, iced coils and noisy units. Plus filter swaps and pre-summer tune-ups so your AC is ready before the next heat wave hits.

02

Furnace Fixes & Annual Service

Ignition failures, cold spots, worn igniters, blowers and belts. Yearly heater inspections and part replacements before the first cold snap of the season.

03

New AC Systems

Central air installs for Valley homes. I run the load math myself, walk you through equipment options in plain English, and give you a straight-talk quote before any purchase.

04

New Furnace Installs

Residential furnace and heat-pump installations. I compare efficiency ratings against your actual usage — so your utility bill drops after the swap, not just the manufacturer's brochure.

05

Diagnostics You Can Trust

Deep diagnostics for weird HVAC behavior — short cycling, high bills, uneven rooms. I chase the root cause first, so you don't pay for parts that don't fix the actual problem.

06

Indoor Air Quality

Whole-house filtration, UV and duct sealing. Critical in the Valley when summer smog and wildfire smoke pile up — cleaner air for allergies, asthma and everyone in between.

FROM 100° TO COLD AIR IN 3 STEPS

1

Call the owner

Ramiro picks up — not a call center. Tell him what's wrong, get real answers and a same-day arrival window.

2

Flat-rate quote

Tech shows up in uniform, diagnoses on the spot, and gives you the total price before touching a single wire.

3

Cool by sundown

Most jobs done in one visit — you sleep in a cold house tonight. Backed by 20+ years of hands-on experience and my personal word.

What neighbors say

★★★★★
I recently had my air conditioning system serviced by CA Comfort, and I couldn't be happier with the experience. Ramiro arrived on time, was professional, knowledgeable, and took the time to explain everything clearly. He quickly diagnosed the issue, completed the repair efficiently, and made sure everything was working perfectly before leaving.

★★★★★
CA Comfort has been servicing my units for many years. Having an older system and not quite ready to install a new unit, Ramiro has been very honest and helpful in troubleshooting to make sure our system is maintained and working efficiently. We value his expert advice and honesty.

★★★★★
Called Ramiro after another company quoted me way too high for what turned out to be a small refrigerant issue. He came out the same day, walked me through what was really going on, and charged a fair price. Honest and to the point. Hard to find these days.

★★★★★
Our AC stopped cooling right in the middle of summer with the family visiting. Ramiro squeezed us into his schedule the same afternoon, found a bad capacitor, and had us cold again in about an hour. Straightforward guy, no upsell. He'll get every call from me from now on.

AFFORDABLE, HONEST SERVICE.
“IT’S 100° OUT THERE. I TREAT YOUR AC LIKE AN EMERGENCY.”

I’ve spent the last 20+ summers on Valley rooftops and in hot attics, fixing every brand of AC out there. I built CA Comfort so homeowners could skip the big-company markup and get the guy who actually does the work — me. That’s why my prices are honest, my quotes are flat, and my phone stays on through every heat wave. If you call, you get me. If I quote it, I stand behind it.

Questions I get every day

Anything not covered here? Just call (818) 516-4881.

How fast can you actually get here?

Same day, anywhere in the San Fernando Valley, Ventura County or Greater LA. During summer heat waves I prioritize no-cooling calls — most customers see me within 2–4 hours, even on 100°+ days.

Do you cover heat-wave emergencies?

Yes. During heat waves I extend my hours and run Saturdays. If your AC is out and it's dangerously hot, call — I'll get you on the schedule the same day whenever I possibly can.

Why are your prices lower than the big companies?

I'm owner-operated with no franchise fees, no giant office, no commission-based salespeople. That overhead lives on your invoice at the big shops — not with me.

Which brands do you service?

Every major brand — Carrier, Trane, Lennox, Goodman, Rheem, Daikin, York, Bryant and more. 20+ years means I've seen and fixed them all.

Is the estimate really free?

Yes — free in-home estimates on installs, replacements and air-quality systems. On repairs, the diagnostic fee is waived when you go ahead with the fix.

Are you licensed?

Yes — I hold a California CSLB HVAC/Mechanical Contractor license (#898086), carry full liability insurance, and I'm EPA-certified for refrigerant handling. Verify me on the CSLB website anytime.

DON'T SWEAT ANOTHER 100° NIGHT.

One call to Ramiro. Same-day fix, affordable flat price, cold air moving before bedtime. Backed by 20+ years of Valley summers.
