## Frequently asked questions
Q: Where can I find HVAC repair near me in Los Angeles?
A: LC Heating & Air is based at 509 N Fairfax Ave and serves Greater Los Angeles with same-day service when scheduling allows. Call (323) 970-3113 — emergency calls answered 24/7, typically within 30 minutes.

Q: How much does AC repair cost in Los Angeles?
A: Most AC repairs in Los Angeles run about $150–$800 for common parts (capacitors, contactors, thermostats, sensors), after a $125 diagnostic that applies toward the repair when you approve the work. Compressor, coil, or refrigerant-leak repairs cost more and are always quoted in writing first.

Q: Do you offer same-day AC repair in Los Angeles?
A: Yes — we offer same-day AC and heating service across LA when the schedule allows. For urgent no-cool or no-heat situations, call anytime; we answer 24/7 and dispatch as quickly as possible.

Q: Why hire a CSLB-licensed HVAC contractor?
A: Unlicensed work can void equipment warranties and leaves you without proper insurance if something fails. LC Heating & Air operates under CSLB License #1073586 with liability and workers compensation coverage.

Q: Should I repair or replace my 15-year-old HVAC system?
A: Use the 5,000 Rule : multiply system age by the repair quote — if the result exceeds about $5,000, replacement is usually smarter. At 15+ years, low efficiency and obsolete refrigerant often make replacement the better long-term value; we will tell you honestly if a smaller repair is enough.

Q: Why is my AC blowing warm air?
A: Warm air usually means low refrigerant (leak), a dirty filter restricting airflow and freezing the coil, or a failed outdoor capacitor. Check the thermostat and replace the filter first; if it stays warm, shut the system off and call for service to avoid compressor damage.

Q: What HVAC brands does LC Heating & Air service?
A: We service and install major brands including Carrier, Lennox, Trane, Rheem, Goodman, Daikin, Mitsubishi, and more. Because we are not tied to one manufacturer, we recommend equipment that fits your home rather than a single product line.

Q: Do you offer financing for new HVAC systems?
A: Yes — financing is available through approved lending partners for qualifying customers, including promotional options on larger replacements. We review choices during your in-home estimate so you can compare monthly payment scenarios.

Q: Are there California rebates for replacing my AC with a heat pump?
A: Yes — qualifying heat pump upgrades can access TECH Clean California rebates plus federal IRA tax credits. Amounts depend on equipment and income limits; we identify programs during your estimate and help with paperwork when eligible.

Q: Do you warranty HVAC repairs and installations?
A: Yes — we stand behind our labor and register manufacturer equipment warranties on installs. Warranty terms vary by repair type and equipment; we explain coverage in writing before you approve the job.

Q: How fast can LC Heating & Air respond in Los Angeles?
A: We offer same-day HVAC service across Greater Los Angeles. Emergency calls are answered 24/7, typically within 30 minutes.

Q: Is LC Heating & Air licensed and insured?
A: Yes. LC Heating & Air holds California Contractors State License Board license #1073586 and carries liability and workers compensation coverage on every job.

Q: What HVAC services do you handle?
A: We provide AC repair and installation, furnace repair and replacement, mini split systems, heat pumps, duct cleaning, indoor air quality upgrades, maintenance, and emergency HVAC service.

Q: Do you give written estimates before work starts?
A: Yes. Every job starts with a written estimate and a clear explanation of what we found, what we recommend, and what it costs before any work begins.

Q: How much does furnace repair cost in Los Angeles?
A: Typical furnace repairs in LA are often $150–$900 for ignitors, flame sensors, capacitors, or control boards. Heat exchanger or gas-valve work costs more; we diagnose first and give a written estimate before any repair. Emergency calls use the same upfront estimate policy.

Q: How much does it cost to install a new AC in Los Angeles?
A: A new AC installation in Los Angeles usually costs $5,500 to $12,000 , depending on tonnage, SEER2 rating, duct modifications, and permits. We provide free, upfront written estimates before any work begins.

Q: How much does a ductless mini split system cost?
A: A single-zone ductless mini split typically costs $3,500–$6,000 installed. Multi-zone systems (one outdoor unit, several indoor heads) often run $8,000–$18,000 , depending on layout and electrical upgrades.

Q: How much does air duct cleaning cost in Los Angeles?
A: Whole-home duct cleaning in Los Angeles is usually about $400–$900 for a typical single-family home, based on vent count, access, and contamination level. We confirm the price in writing before starting.

Q: Is there an extra charge for emergency HVAC service?
A: We do not add hidden “after-hours surprise” fees without telling you first. Emergency calls are answered 24/7; you still receive a written estimate before approved repair work. The diagnostic/service call fee is disclosed upfront.

Q: When should I call a pro instead of DIY HVAC repair?
A: Call a licensed pro for refrigerant work, gas furnaces, electrical faults, burning smells, carbon monoxide concerns, or any problem involving the compressor or heat exchanger. DIY filter changes and thermostat batteries are fine; anything beyond that risks safety, voided warranties, and EPA violations.

Q: Why is my AC running but not cooling the house?
A: If the system runs but never catches up, common causes are low refrigerant, a frozen evaporator coil, weak airflow from dirty filters or ducts, or an undersized/overworked unit during a heat wave. Turn it off if you see ice, replace the filter, and schedule a diagnostic if cooling does not return.

Q: Why is ice building up on my AC lines or indoor unit?
A: Ice means the coil is too cold — usually from low airflow (clogged filter, closed vents) or low refrigerant. Turn the system off and let it thaw; running it iced can kill the compressor. Do not just “add refrigerant” without finding the leak.

Q: My AC is buzzing but the outdoor fan is not spinning — what is wrong?
A: A loud buzz with a still fan often indicates a failed run capacitor or a seized fan motor. This is a common, usually straightforward repair — turn the system off at the thermostat and call for service before the compressor overheats.

Q: How long do air conditioners last in Southern California?
A: With annual maintenance, expect about 12–18 years for a quality condenser in LA. Coastal salt air can shorten life toward 10–12 years; Valley heat and heavy runtime can stress components faster.

Q: Could my thermostat be why my AC will not turn on?
A: Yes — dead batteries, wrong mode (Heat vs Cool), tripped breakers, or a failed thermostat can mimic a broken AC. Set Cool mode, replace batteries if applicable, and check the breaker; if the outdoor unit still does not start, schedule a diagnostic.

Q: Why does my furnace smell like burning when I turn it on?
A: A short dusty burn-off smell on the first cycle of the season is normal in LA. Shut the system off and call immediately if you smell electrical burning, melting plastic, or sulfur (rotten eggs) — those can indicate serious hazards.

Q: What does a SoCalGas red tag on my furnace mean?
A: A red tag means a critical safety defect — often a cracked heat exchanger leaking combustion gases. Gas must stay off until a licensed contractor repairs or replaces the unit; do not bypass the tag.

Q: Why does my furnace turn on and off every few minutes?
A: Short cycling is usually overheating from a clogged filter or restricted airflow, or a dirty flame sensor shutting the burner off for safety. Replace the filter first; if it continues, schedule service before heat exchanger damage occurs.

Q: What does AFUE mean on a gas furnace?
A: AFUE is the percentage of gas converted into usable heat. An 80% AFUE furnace loses 20% up the flue; a 96% model loses only 4%, which can noticeably lower winter gas bills in older LA homes.
