Frequently Asked Questions — HVAC in California, CA
We've been keeping California homes comfortable since 2006. Here are the questions we hear most often, answered straight.
Pricing & Cost FAQs
A complete HVAC replacement in California typically runs $6,500–$12,000 for a standard 3-ton split system, with high-efficiency variable-speed units reaching $14,000–$18,000. Ductwork replacement adds $3,000–$7,000 depending on home size and accessibility. In older neighborhoods like Avocado Heights and Hacienda Heights, we often find galvanized ductwork from the 1960s that needs full replacement. Permit fees through your local California jurisdiction run $200–$500. We provide itemized quotes before any work begins. Call (844) 560-6978 for a free in-home estimate.
Most AC repairs in California fall between $150 and $650, with refrigerant leaks and compressor issues at the higher end. Capacitor or contactor replacements usually run $150–$300. We see a lot of failed capacitors in South San Jose Hills and Valinda during July heat waves when systems cycle constantly. Refrigerant recharges with R-410A run $400–$800 depending on leak severity. We always check for the root cause rather than just topping off refrigerant. Estimates are free, and we quote upfront before starting work.
Replacement becomes the smarter financial choice when repair costs exceed 40% of a new system's price and your unit is over 12 years old. In California's inland valleys, where summer temperatures regularly hit 100°F, an aging inefficient system costs $300–$600 extra per season in electricity. We factor in your unit's SEER rating, repair history, and remaining lifespan. For a 15-year-old system needing a $2,800 compressor, replacement usually wins. We'll walk you through the math honestly. Call us at (844) 560-6978 for a no-pressure assessment.
Furnace repairs in California range from $120 for ignitor replacements to $900–$1,400 for heat exchanger work. In Plumas Lake and Fairfield, where winter nights dip into the 30s, we see more cracked heat exchangers from rapid cycling. Blower motor replacements run $400–$700. We always perform combustion analysis after any furnace repair to verify safe operation. Carbon monoxide testing is included at no charge. Free estimates, and we stock common parts for same-day completion.
California's Title 24 energy codes, seismic bracing requirements, and higher refrigerant handling standards add 15–25% to installed costs versus the national average. Permit and inspection processes are more rigorous, especially in San Jose and West Covina. We also deal with higher shipping costs for equipment and the need for specialized training on low-GWP refrigerants like R-32. These regulations ultimately save you money on utilities and improve safety. Our quotes include all compliance costs with no hidden fees.
Service & Process FAQs
Our California tune-up covers 22 points: refrigerant pressure testing, electrical connection tightening, capacitor and contactor inspection, blower wheel cleaning, condensate line clearing, and full thermostat calibration. We measure temperature split across the coil and check for duct leakage with a visual pressure test. In West Puente Valley and La Puente, we pay extra attention to condenser coils clogged with Santa Ana wind dust. The visit takes 60–90 minutes. We leave you with a written report and priority scheduling for any follow-up.
A straightforward replacement takes one day; full system changes with ductwork require 2–3 days. In Hacienda Heights and Avocado Heights, tight attic access or hillside foundations sometimes add half a day. We pull permits before arrival, coordinate inspections, and handle all Title 24 documentation. Your home won't be without heating or cooling overnight during a standard replacement. We confirm the timeline during your estimate and stick to it. Marcus Feldman personally reviews every installation schedule.
Every 30–60 days during peak use, or every 90 days minimum year-round. California's wildfire season and valley dust mean filters load faster than in coastal climates. In Suisun and Fairfield near agricultural areas, we've pulled filters completely clogged after three weeks. We recommend MERV 8–11 for most homes; higher MERV ratings restrict airflow in older duct systems. Check your filter monthly by holding it to light. Can't see through it? Time to change. We stock common sizes and can set up auto-delivery.
Most California homes need 1 ton of cooling per 400–600 square feet, but proper sizing requires a Manual J load calculation. We measure insulation, window efficiency, duct leakage, and solar heat gain. An oversized unit in San Jose's mild climate short-cycles and dehumidifies poorly; undersized in Valinda's 105°F summers runs constantly and fails early. We never guess by square footage alone. Our load calculations are included free with replacement estimates.
Yes, if your system has a fresh filter and you keep windows sealed. Recirculate mode prevents drawing in smoky outside air. We recommend upgrading to a 4-inch MERV 13 media filter or adding an electronic air cleaner during wildfire months. In 2020's Creek Fire, we helped dozens of Plumas Lake families maintain safe indoor air quality. If your home smells of smoke with the system running, call us immediately; duct leaks may be pulling in attic air. We offer same-day filter upgrades and duct sealing.
Brands & Parts FAQs
We install Rheem and Daikin most often for California's hot summers and mild winters. Rheem's Prestige Series handles sustained 100°F days well, with compressor warranties up to 10 years. Daikin's inverter-driven systems excel in San Jose's moderate climate, running efficiently at partial load most of the year. For homes in South San Jose Hills with limited electrical panels, Daikin's low-startup-amp compressors prevent service upgrades. We also service and install York and Bryant. Every recommendation is matched to your home, not our inventory.
We use OEM parts for compressors, control boards, and heat exchangers; aftermarket is fine for capacitors, contactors, and some sensors. Generic compressors often lack the exact charge specifications for California's high-ambient conditions, leading to premature failure. In 19 years, we've seen too many "compatible" control boards fail within two seasons in West Covina's heat. Our parts carry 1–5 year warranties depending on component. We show you exactly what we're installing and why.
Single-stage runs full blast or off; variable-speed modulates between 25% and 100% capacity. In California's shoulder seasons, variable-speed systems run longer at lower output, removing more humidity and using 40% less electricity. The upfront cost is $2,000–$4,000 higher, but SCE and PG&E rebates often offset $1,000–$2,500. For La Puente and Valinda homes with high summer bills, payback typically hits in 4–6 years. We calculate exact savings using your utility history during estimates.
Licensing & Insurance FAQs
Yes, we're fully licensed by the California Contractors State License Board for HVAC work statewide. Marcus Feldman holds personal certifications in EPA Section 608 universal refrigerant handling and NATE Core plus specialties. All our technicians complete continuing education on California's evolving Title 24 standards and low-GWP refrigerant transitions. We carry general liability and workers' compensation insurance. License verification and certificate of insurance available on request. We've maintained clean records since 2006.
Permits are required for all system replacements, new installations, ductwork modifications, and gas line work in California. Repairs like capacitor swaps or refrigerant top-offs generally don't need permits. We handle permit applications, fees, and inspections as part of every installation. In San Marcos and San Jose, some jurisdictions require Title 24 compliance documentation we prepare. Unpermitted work can void insurance coverage and complicate home sales. Never let a contractor skip permits to save money.
Check the CSLB license number online, confirm active insurance certificates, and ask for local references from the past 30 days. Search the company name plus "review" or "complaint." A legitimate California contractor has a physical address, not just a PO box. Marcus Feldman encourages every homeowner to verify us; we've earned 250 verified reviews averaging 4.8 stars through transparent work. Be wary of anyone demanding full payment upfront or offering "today only" pressure pricing.
Emergency & Response FAQs
We complete 85% of same-day calls when contacted before 2 PM, and we offer true emergency service until 10 PM. Our trucks carry $50,000 in inventory including capacitors, contactors, motors, and refrigerant. In San Marcos and Fairfield, we stock extra hard start kits for aging compressors that fail during heat waves. After 10 PM, our on-call technician returns messages within 15 minutes for true emergencies like complete system failures with vulnerable residents. Call (844) 560-6978; we'll give you an honest arrival window.
What counts as an HVAC emergency in California?
Replace your filter, clear debris within 2 feet of the condenser, and raise your thermostat 2–3 degrees to reduce runtime stress. Pre-cool your home to 72°F by 10 AM before peak afternoon temperatures. In Suisun and Plumas Lake, where 110°F days are increasingly common, we recommend a pre-season tune-up in April. Shade your condenser if possible, but never cover it during operation. If your system is over 12 years old, have us inspect it before the first major heat event. Preventive calls are far cheaper than emergency repairs.
Warranty & Guarantees FAQs
Equipment warranties run 5–10 years on parts and 10 years to lifetime on compressors from manufacturers like Rheem and Daikin. We add our own 2-year labor warranty on all installations, extendable to 5 years with our maintenance plan. California's strong consumer protection laws mean manufacturers honor warranties here reliably. Registration is required within 60 days; we handle this for you. Transfer to a new homeowner is usually free if done within 90 days of sale. Warranty terms are written into every contract, not promised verbally.
Yes. If your new system doesn't maintain the temperature we promised within 30 days, we'll return at no charge to adjust, repair, or replace components. If you're still unsatisfied, we'll remove the equipment and refund 100% of installation costs. This has happened twice in 19 years; both times we learned something and improved. Our 250 reviews averaging 4.8 stars reflect how rarely it's needed. Marcus Feldman stands behind every installation personally.
Our California Comfort Plan includes two tune-ups annually, 15% repair discounts, priority same-day scheduling, no after-hours fees, and waived diagnostic charges. We track your system's performance history and flag declining efficiency before failures. In West Covina and Hacienda Heights, where salt air from coastal fog accelerates corrosion, we include annual coil treatment. Plan members receive first access to limited rebate programs from utilities. The plan pays for itself with one avoided emergency call. Ask about enrollment during your next service.
