San Jose HVAC, Done Right

When you need a trusted heating and cooling company in San Jose, Newark HVAC is the company to call. We've been keeping local homes and businesses comfortable year after year, building our reputation one satisfied neighbor at a time. Our technicians are local, not dispatched from across the state, which means faster response times and a real understanding of the climate patterns, housing stock, and ductwork quirks that shape how HVAC systems here perform and fail.

From a single furnace that won't light to complete system replacements, ductless mini-split installations, and seasonal maintenance programs, our team handles every kind of residential and commercial heating and cooling need. We offer prompt service and give you a clear, written quote before any work begins, no hidden fees, ever. Our trucks are stocked with the parts that fail most, capacitors, contactors, igniters, flame sensors, blower motors, and thermostats, so most repairs are finished in a single visit.

Whether your air conditioner is tripping the breaker, your furnace is short-cycling, or you're simply planning ahead for a system past its prime, one call to (510) 201-4778 gets a skilled local technician headed your way with everything needed to diagnose the problem quickly.

Heating and Air Conditioning Service Across San Jose

Whether you own a single-family home, a small apartment building, or a commercial space in town, we have the know-how and equipment to handle the full range of heating and cooling work. Our technicians bring years of hands-on experience with central air conditioners, gas and electric furnaces, heat pumps, and ductless mini-splits throughout the area, and we pay close attention to the climate patterns, housing stock, and local code requirements that shape how systems perform here.

Most homeowners we work with need one of three things: a repair, a replacement, or a seasonal tune-up. Repairs are usually straightforward: a burned contactor, a dirty flame sensor, a slow refrigerant leak, or a seized blower motor. Replacements get a proper load calculation, not a guess based on the old unit's tonnage, which keeps temperatures even and stops the new equipment from short-cycling its way to an early failure. Tune-ups cover coil cleaning, a refrigerant charge check, safety control testing, and a static pressure reading, and nothing does more to extend equipment life.

Local businesses get the same attention. An overheated storefront or a drafty office costs real money, so our commercial crews focus on getting to the cause quickly and keep common parts on board for rooftop units, split systems, and ventilation equipment. Property managers, restaurant owners, and retailers can count on us to work around their operating hours whenever we can.

When Your System Fails in San Jose

Heating and cooling failures rarely wait for a convenient day, which is why we offer fast, flexible scheduling for most situations. When you call, you'll reach a real person who will get a technician headed to your property without delay. Arrival in the area is usually within a day for urgent calls, and a dead AC in a heat wave or a furnace out on a freezing night is exactly the kind of call we move to the front of the line.

Common emergencies we handle include air conditioners blowing warm air, outdoor units that hum but won't start, furnaces that ignite and then shut down, breakers that trip every time the system runs, frozen evaporator coils, clogged condensate drains backing up into the furnace cabinet, and thermostats that have stopped responding. Our trucks carry the capacitors, contactors, igniters, flame sensors, universal control boards, and fittings needed to finish most repairs in a single visit. Pricing is always upfront, so you know exactly what the work will cost before we begin.

A little caution before we arrive can prevent a much larger repair. A frozen air conditioner should be shut off at the thermostat with the fan set to "on", which lets the coil thaw faster. Running it frozen risks an overflowing drain pan and a damaged compressor. A furnace that keeps short-cycling, or any burning smell, means it's time to shut the unit off at its service switch and call us immediately.

How San Jose Homeowners Can Extend HVAC Life

Most mid-season breakdowns trace back to skipped maintenance, and the habits that prevent them are easy. Swap your filter every one to three months, clear vegetation at least two feet from the outdoor condenser, and rinse the condenser coil once a year in spring. Then book a professional tune-up each spring and fall, one for cooling and one for heating, so our technicians can catch small problems while they're still cheap to fix.

The age of your equipment matters just as much. With regular service, central air typically lasts 12 to 15 years, a furnace 15 to 20, and a heat pump 10 to 15. Once a system passes that range and starts showing warning signs, like higher energy bills, rooms that won't reach the setpoint, or one repair after another, it's smart to start planning a replacement. Replacing on your own schedule is cheaper and is far less stressful than an emergency swap during the first heat wave of summer.

If comfort problems do show up, acting quickly keeps them small. A weak capacitor is a quick fix. The same capacitor left alone for a season can take the compressor with it and turn a minor repair into a full system replacement. It's smart to keep our number saved on your phone so you can reach us at the first sign of trouble. Early intervention saves time, money, and miserable nights.

Comfort Challenges San Jose Homeowners Face

Most local HVAC failures announce themselves before they happen. A breaker that trips more than once, a condenser that hums louder each month, rooms drifting further from the thermostat setting, a musty smell at startup. Those are early signs of failing capacitors, refrigerant leaks, dirty coils, and duct problems, and caught early they're an affordable repair. Ignored, they take out compressors and heat exchangers, the two most expensive parts in the system. We diagnose the cause, not just the symptom, so small problems stay small.

The Reason San Jose Keeps Calling Us

Choosing an HVAC company comes down to trust, and trust has to be earned. Newark HVAC earns it by fixing what's fixable instead of replacing what isn't, by sizing replacements with real load calculations instead of guesswork, and by standing behind every repair long after the visit ends. We keep response times short throughout the area, and each visit wraps up with the system tested and your questions answered.

Your HVAC Questions Answered

Most calls get a same-day appointment, and a home with no heat or no cooling gets priority over routine work. When you reach us at (510) 201-4778, you'll get a realistic arrival window, and since the technician arrives with capacitors, contactors, igniters, and motors on the truck, the job usually wraps up in one trip.
Every major brand, such as Carrier, Trane, Lennox, Rheem, Goodman, and York, plus ductless systems from Mitsubishi, Fujitsu, and LG. Our technicians carry universal parts that fit most units and can order brand-specific components quickly when a repair requires them.
Start with a few quick checks: confirm the thermostat is set to cool with working batteries, pull the filter and check for a clog, and look for a tripped breaker on both the indoor and outdoor units. If none of that helps and the outdoor unit hums but won't start, or you see ice on the copper lines, turn the system off before the compressor is damaged. Then call (510) 201-4778 and we'll send a technician to your home as fast as we can.
It comes down to age and which part failed. Under about 10 years, most component failures are well worth repairing. Past 15 years, or any time a compressor or heat exchanger fails, replacement is usually the smarter investment, especially with the efficiency gains of new equipment. We give you both numbers straight and let you make the call. We'd rather earn your trust than sell you a system early.
Yes, we offer seasonal maintenance for homes throughout the area. The spring visit covers cooling: coil cleaning, a refrigerant charge check, capacitor testing, and airflow readings. The fall visit covers heating: cleaning the burners, checking combustion, and testing every safety control. Keeping up with both visits adds years to your equipment, helps prevent breakdowns in the middle of a heat wave or cold snap, and usually pays for itself in energy savings.
We do, and we'll help you decide which makes sense. We fix AC systems, furnaces, heat pumps, and mini-splits no matter who made them. If replacement is the better call, we handle everything: old equipment removal, a correctly sized new system, careful installation, and a full test of every mode. You get a clear quote for both paths before making a decision.
Yes. Mini-splits are ideal for additions, garages, sunrooms, and older homes that never had ductwork. We size each zone to the room it serves, position the indoor and outdoor units carefully, and take care of the line set, condensate drainage, and electrical connections properly. If central equipment serves you better, we'll say so.
It depends on what's wrong. Repairs usually come in between $150 and $650, based on the failed part and the type of system. A full replacement typically costs around $5,000 to $12,000 installed, with size and efficiency making the difference. Before we begin, we provide a written quote based on the diagnostic, and that number doesn't change.
