Frequently Asked Questions

Frequently Asked Questions – Crestview Heating & Air California

These are the questions San Jose homeowners and property managers ask us most often. Every answer comes straight from Marcus Feldman, who has spent 19 years in the field and still manages service calls personally. If your question isn’t here, call us at (844) 560-6978 – we’ll give you a straight answer, not a runaround.

Pricing & Estimates

How much does HVAC service cost in San Jose?

HVAC service in San Jose typically ranges from $89 to $299 for a diagnostic and standard tune-up, while repairs run anywhere from $150 to $1,800 depending on the failed component and the system’s age. Installations for a central AC system in a San Jose home generally fall between $4,500 and $12,000 installed, depending on the tonnage, efficiency rating, and whether ductwork needs modification. Mini split installations often land between $1,800 and $5,500 per zone. We don’t give ballpark numbers just to get in the door – when we show up, we look at your actual system and give you a real price before any work starts. Call (844) 560-6978 for a free estimate on your specific situation.

Do you offer free estimates?

Yes – we provide free estimates for new equipment installations and system replacements. For diagnostic and repair calls, there is a service fee, which gets applied toward the repair if you choose to move forward with us. We find that most homeowners in Willow Glen, Almaden Valley, and across San Jose appreciate knowing the fee upfront rather than getting surprised after someone has already opened their system. Nothing gets done without your approval first. Call (844) 560-6978 to schedule yours.

What payment methods do you accept?

We accept all major credit cards, debit cards, checks, and cash. For larger projects like full system replacements or commercial work, we also offer financing options so the cost doesn’t have to hit all at once. Ask us about current financing terms when you call – the details can change, and we’d rather tell you what’s available right now than print something here that goes stale.

Is it cheaper to repair my HVAC system or replace it?

The honest answer depends on your system’s age, the cost of the repair, and its efficiency rating. A commonly used rule in the industry is to multiply the repair cost by the system’s age – if that number exceeds $5,000, replacement often makes more financial sense over a 5-year horizon. In San Jose’s climate, where AC systems run hard from May through October, an older, inefficient system also carries a real energy cost that a newer unit eliminates. Marcus evaluates this during every major repair call and gives you the honest numbers – not a push toward whichever option costs more. Call (844) 560-6978 and we’ll walk through it with you.

Service, Scheduling & Response

Do you offer emergency HVAC service?

Yes, Crestview Heating & Air California offers emergency HVAC service for situations where waiting until the next business day isn’t an option. San Jose summers can push indoor temperatures into dangerous territory quickly – particularly in neighborhoods like East San Jose and Evergreen where homes can hold heat – and a furnace failure during a cold night in the Almaden hills is equally urgent. When you call (844) 560-6978 outside normal hours for an emergency, we’ll let you know availability and get someone to you as fast as possible.

How fast can you respond to a service call?

For standard service calls in San Jose and surrounding areas, we typically schedule within one to two business days. Same-day appointments are often available, especially earlier in the week or outside peak summer season. Emergency calls are handled with priority scheduling – response time varies based on current call volume and technician location, but we’ll always give you an honest arrival window when you call rather than a vague “sometime today.” We cover a broad service area, so your neighborhood matters; areas close to central San Jose tend to see the fastest availability.

What areas do you serve?

We serve San Jose and the surrounding South Bay communities, including Campbell, Milpitas, Santa Clara, Sunnyvale, Los Gatos, Saratoga, and Morgan Hill. Within San Jose itself, we work throughout Willow Glen, Almaden Valley, Blossom Hill, Berryessa, Evergreen, East San Jose, Silver Creek, and Downtown. If you’re not sure whether you’re in our service area, just call (844) 560-6978 – if we can get to you reliably, we’ll tell you so. If you’re outside our usual range, we’ll tell you that too.

How do I schedule a service appointment?

1. Call (844) 560-6978 – a real person picks up, not an automated queue. Tell us your system type, brand if you know it, and what it’s doing (or not doing).
2. We’ll ask a few quick questions – age of the system, whether it’s a repair, tune-up, or installation, and your address so we can route correctly.
3. We confirm a time window – we’ll give you an actual arrival window, not a 6-hour block that wastes your day.
4. Marcus or a tech arrives and assesses – we inspect the system before quoting any work. Nothing gets authorized without your sign-off.
5. Work is completed or a follow-up is scheduled – most repairs are done same visit. If a part needs to be ordered, we’ll give you an ETA before we leave.

Licensing, Trust & Guarantees

Are you licensed and insured?

We’re not going to make a licensing or insurance claim here without having the specific credentials in front of you – that’s exactly the kind of vague assurance that every HVAC company says and almost none back up with verifiable details. What we can tell you is that after 19 years serving San Jose and with 250+ customers who left public reviews averaging 4.8 out of 5, our track record speaks clearly. Call us at (844) 560-6978 and ask directly – Marcus will give you straight answers about our credentials, not boilerplate language.

Do you guarantee your work?

Yes, we stand behind every repair and installation we perform. The specifics of the workmanship guarantee vary by job type – a repair carries a different warranty structure than a full system installation, and manufacturer equipment warranties layer on top of our own labor guarantee. Rather than printing a generic “X-year guarantee” here that may not match your specific situation, we’d rather walk you through what applies to your job before we start. That’s how Marcus has operated for 19 years, and it’s why customers in San Jose keep calling us back rather than shopping around each time.

Who actually shows up to do the work?

Marcus Feldman, who owns Crestview Heating & Air California, also serves as Service Manager – which means ownership-level oversight is built into every job, not just the pitch. On many calls, Marcus is the one in your home or mechanical room. On the jobs he doesn’t run personally, he manages the dispatching and reviews the work. We’re not a franchise where an unknown technician shows up with a logo on the truck and no accountability behind it. That structure – owner as service manager – is the core of how we operate, and it shows in the consistency of those 250+ reviews.

How long has Crestview Heating & Air California been in business?

We’ve been working in the HVAC industry for 19 years, with roots in San Jose and the South Bay. Nearly two decades in one market means we know the quirks of older homes in Willow Glen, the duct configurations common in 1990s-era tract homes in Evergreen, and the commercial HVAC demands of the office and industrial buildings spread across north San Jose near the airport corridor. That kind of local familiarity shortens diagnostic time and produces better outcomes – it’s not something you build overnight.

Specific Services

Do you handle AC repair and installation?

AC repair and installation is one of our core services in San Jose. We diagnose and repair everything from refrigerant leaks and failed capacitors to compressor issues and thermostat malfunctions, and we install new systems from Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. San Jose’s heat season arrives fast – temperatures in Almaden Valley and Silver Creek regularly push past 95°F in July and August, and a system that’s limping in May won’t survive a full summer. Our AC Repair & Installation in California service page covers the full detail of what we offer, or call us directly at (844) 560-6978.

Do you handle heating and furnace service?

Yes, we service, repair, and replace gas furnaces, electric furnaces, and heating systems across all the major brands we carry. San Jose winters are mild by most standards, but a furnace that fails in January still leaves a family in a cold house, and older homes in neighborhoods like Naglee Park or Rose Garden often have aging systems that need attention. We handle everything from a no-heat diagnostic to a full furnace replacement, and we’re familiar with the ventilation and venting requirements specific to California building codes. If your furnace is short-cycling, blowing cold air, or making a sound it didn’t make last season, that’s a call worth making before the cold sets in.

Do you handle heat pump and mini split installation and repair?

Heat pumps and mini splits are a growing part of what we do in San Jose, particularly as California’s energy policies continue to push electrification and homeowners look for alternatives to central ducted systems. We install and service both single-zone and multi-zone mini split systems, and we work with heat pump systems from Daikin, Carrier, Lennox, Trane, and other brands in our lineup. Mini splits are especially practical for older San Jose homes that lack duct infrastructure, garage conversions, and ADUs – we see a lot of those in Cambrian Park and the Blossom Hill area. Call (844) 560-6978 to talk through whether a heat pump or mini split makes sense for your space.

Do you handle air quality and ventilation?

Air quality and ventilation services are part of our full-service offering in San Jose. We install and service whole-home air purifiers, UV air treatment systems, HEPA filtration upgrades, humidifiers, dehumidifiers, and ventilation systems including ERVs and HRVs. In San Jose, air quality concerns are real – wildfire smoke season affects the South Bay every summer and fall, and older homes with poor attic or crawlspace ventilation can trap contaminants year-round. If you’ve noticed more dust, inconsistent humidity, or allergy symptoms that seem tied to time spent indoors, there’s usually a system-level fix. We’ll assess what’s actually happening before recommending anything.

Do you service commercial HVAC systems?

Yes, we service commercial HVAC systems for small-to-mid-size businesses and property managers in San Jose and the surrounding South Bay. That includes rooftop units, split systems, and packaged units commonly found in office buildings, retail spaces, and light industrial facilities. Commercial jobs get the same direct involvement from Marcus as residential ones – you’re not handed off to a separate commercial division with different accountability standards. If you manage a building in north San Jose’s tech corridor or a retail strip in Campbell and you need reliable HVAC service without the runaround, we’re worth a call.

What HVAC brands do you work on?

We’re factory-trained on nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. That breadth matters in a city like San Jose, where the housing stock spans several decades and almost every brand has been installed in volume at some point. We never tell a customer we “don’t work on that” – and with 19 years in the market, there are very few system types or configurations we haven’t already seen. If you’re not sure whether your system is in our wheelhouse, just call (844) 560-6978 and tell us what you have.

Can you help me figure out why my energy bills are so high?

High energy bills tied to HVAC are usually caused by one of a few things: an aging, inefficient system, duct leakage, incorrect system sizing, or a refrigerant issue causing the unit to work harder than it should. San Jose’s electricity rates are among the highest in California, which means even moderate efficiency losses show up clearly on a utility bill. Marcus has been diagnosing this kind of problem for nearly two decades and can usually identify the source in a single visit. We’ll give you an honest assessment and the repair or upgrade options – you decide what makes sense.

• Dirty or clogged air filter – check and replace first; it’s free and worth ruling out.
• Refrigerant undercharge – a system low on refrigerant runs longer and cools less.
• Duct leakage – studies suggest 20-30% of conditioned air is lost to leaky ducts in many California homes.
• Oversized or undersized equipment – a system that short-cycles or runs constantly wastes energy regardless of its efficiency rating.
• Aging equipment – a 15-year-old system running at SEER 10 costs significantly more to operate than a modern SEER 18+ unit over a San Jose summer.
