★★★★★

I cannot thank South County Air Services enough for impeccable customer service. Behshad came out on a Saturday to check my heating unit (failing motor). He was professional, knowledgeable, courteous and thorough – extremely fair pricing, with open and honest communication. Highly recommend. Five star plus!

I am grateful to the technician who inspected my HVAC system today. I feel he did a thorough inspection and told me the truth about my unit. I had two other companies beforehand – the first gave me a report that would call for major expenditure.

You will not find a more honest and knowledgeable HVAC tech. They show up on time and are very professional, but most of all will not try to upcharge you. He could have charged me significantly more but cares about diagnosing the actual problem. I found my HVAC tech – 10 star review if I could!

It’s not often you find an honest business willing to give suggestions over the phone to troubleshoot why my HVAC wasn’t working – without charging me. After a couple minutes we determined my breaker popped and all I needed was to reset it. I appreciate Behshad and will definitely use him in the future.

I spoke with the owner on a Saturday morning and he was at my house within 45 minutes. Another company wanted $3,000 in repairs; Behshad recommended a simple $250 repair that fixed the issue. Very honest, thorough, and reliable!

Common questions from Price Calculator homeowners

How much does AC repair cost in Price Calculator?

Most AC repairs in Price Calculator run about $150–$600 depending on the part — a failed capacitor is roughly $150–$300 and a refrigerant recharge $300–$600, plus a diagnostic fee. We quote a flat rate before any work starts, so there are no hourly surprises.

How much does it cost to replace an AC or HVAC system in Price Calculator?

A like-for-like AC or furnace replacement in Price Calculator typically runs about $12,000 to $16,000 for a gas system (new AC and gas furnace), or $11,000 to $15,000 for a 3-ton heat pump; premium brands, higher-efficiency equipment, and larger homes run toward the top, past $18,000 for high-end variable-speed systems, depending on size, SEER2 efficiency, ductwork, and permit or HOA factors. You get a written flat-rate quote, and we never upsell equipment you do not need.

Do I need a permit to replace my AC or furnace in Price Calculator?

Yes. California requires a permit for any AC or furnace replacement in Price Calculator — even a like-for-like swap — plus a HERS test (duct-leakage and refrigerant verification). As your licensed contractor (CSLB #1062690) we pull the permit and handle the inspection, so the work is code-compliant and documented for resale.

How long does an AC system last in Price Calculator?

With regular maintenance, most AC systems in Price Calculator last about 12–15 years, and up to about 20 with good care. Price Calculator’s inland summer heat means longer run times, so skipping maintenance shortens that noticeably.

Why is my AC not blowing cold air?

The most common causes are low refrigerant from a slow leak, a failed capacitor, a frozen evaporator coil, or a clogged air filter. It is usually a repair, not a replacement — we diagnose the actual cause and show you the failed part before quoting.

How often should I change my HVAC filter?

Every 60–90 days for a standard 1-inch filter, or monthly during heavy summer use or with pets. It is the cheapest thing you can do to protect the system and keep energy bills down.

Do you offer same-day or emergency HVAC repair in Price Calculator?

Yes — same-day and Mon-Sat emergency AC and furnace repair across Price Calculator and south Orange County. Call (949) 933-3130 and we will get a technician out fast with a flat-rate price before any work begins.

Who is the best HVAC company in Price Calculator?

We will let the reviews speak — South County Air Services holds a 5.0-star rating across 250+ reviews. Family-owned, owner-operated, licensed (CSLB #1062690), a Bryant dealer, with flat-rate pricing and no upsells.
