When you need a dependable heating and cooling company in San Diego, Simi Valley HVAC is the company to call. We've been keeping local homes and businesses comfortable through every season, earning repeat business one job at a time. Our experienced technicians live and work in the area, which means shorter waits 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 no-cool emergency 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 fast service and give you upfront pricing before any work begins, no hidden fees, ever. Our trucks carry 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 running nonstop without cooling, your furnace is clicking but never lighting, or you're simply planning ahead for a system past its prime, one call to (805) 209-1677 gets an experienced local technician headed your way with everything needed to restore your comfort quickly.

Complete Heating & Cooling Services for San Diego Properties

We service every type of heating and cooling equipment you'll find in local homes and businesses, from central air conditioners and gas furnaces to heat pumps and ductless mini-splits. It makes no difference whether the building is a starter home, a condo, or a storefront. Our techs know the local climate, the age and construction of local homes, and the code requirements that apply to new installations, and that knowledge shows up in every diagnosis.

Most homeowners we meet need one of three things: a repair, a replacement, or regular maintenance. Repairs are usually quick: a failed capacitor, a corroded 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 itself to an early death. Maintenance visits cover coil cleaning, a refrigerant charge check, safety control testing, and a static pressure reading, and nothing does more to extend equipment life.

Commercial work is a big part of what we do as well. We maintain and repair rooftop units, split systems, and ventilation equipment for restaurants, shops, offices, and multi-unit properties, and we know that every hour of downtime costs your bottom line. To keep that downtime short, we keep common commercial parts stocked, diagnose quickly, and plan repairs around your operating hours whenever possible.

When Your System Fails in San Diego

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 speak with a real person who will get a technician headed to your door without delay. Arrival in the area is typically 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.

These are the problems that come up most when something breaks at home: warm air from the AC, a condenser that hums but won't start, a furnace that lights for a few seconds and quits, a breaker that keeps tripping, an evaporator coil that has iced over, a condensate drain overflowing into the furnace cabinet, or a thermostat that has quit. Nearly all of these come down to a part we already carry: capacitors, contactors, igniters, flame sensors, universal control boards, and standard fittings. You'll see the price up front, and that's the price you pay.

If your AC has iced over, the most helpful thing you can do before we arrive is switch the system off at the thermostat and set the fan to "on" so the coil can thaw. Running it frozen can flood the drain pan and damage the compressor. If a furnace is short-cycling or you smell something burning, shut it down at the switch and call (805) 209-1677. A few minutes of caution can head off a much larger repair.

Getting More Years From Your HVAC System in San Diego

The best way to avoid a mid-season breakdown is simple maintenance. We recommend that homeowners replace filters every one to three months, keep shrubs and grass trimmed two feet back from the outdoor condenser, rinse the condenser coil each spring, and schedule a professional tune-up twice a year, cooling in spring and heating in fall, so small problems get caught while they're still inexpensive.

How old is your system? Its age tells you a lot. Most well-maintained air conditioners reach 12 to 15 years, gas furnaces 15 to 20, and heat pumps 10 to 15. If your system is past that point and is also showing higher bills, rooms that never quite reach temperature, or repeated repairs, it's a strong candidate for a planned replacement, and that's almost always cheaper and easier on everyone than an emergency replacement when the first heat wave hits.

Minor issues don't stay minor for long. Take a weak capacitor: swapping it out is a quick, inexpensive repair, but left alone for a season, it can take the compressor with it, and just like that a minor fix has become a full system replacement. That's why we encourage homeowners to keep our number in their phone and reach out at the first sign of trouble. Catching it early saves money and prevents a miserable night.

Typical Heating & Cooling Issues in San Diego

Ask any homeowner around here what HVAC trouble looks like and you'll hear the same stories: the AC that quit during the hottest week of the year, the furnace that woke everyone up banging at 2am, the system that runs all day but never satisfies the thermostat. Behind those stories are predictable culprits: worn capacitors and contactors, low refrigerant charge, undersized returns, and years of skipped maintenance. Our technicians run into these problems every week and carry the parts to fix most of them on the first trip.

Why San Diego Homeowners Trust Us

Plenty of companies will sell you a new HVAC system. Simi Valley HVAC earns trust around here by fixing the ones that don't need replacing and being honest about the ones that do. Our technicians diagnose the actual fault before quoting anything, explain your options in plain terms with real numbers, and let you decide without pressure. When replacement is the right call, we size the new system with a proper load calculation for your home's genuine demand, square footage, insulation, windows, and duct capacity, instead of defaulting to whatever's on the truck.

The workmanship holds up because we don't cut corners: correct refrigerant charge weighed in rather than guessed, sealed duct connections, proper condensate drainage, verified combustion and airflow on heating equipment, and clean electrical work that passes inspection the first time. We show up when we said we would, protect your floors, haul away the old equipment, and test the full system in every mode before we pack up. That's why so much of our local work comes from repeat customers and referrals, and why we back every job with a satisfaction guarantee.

Your HVAC Questions Answered

We always quote before we start, so you know the price up front. As a general range, typical repairs cost $150 to $650 depending on the part and system, and complete new systems cost roughly $5,000 to $12,000 installed depending on size and efficiency. Your exact price comes from an on-site diagnostic at your home, and the price you approve is what you pay, with no surprise line items.
The brand name on the cabinet rarely matters. Our technicians work on Carrier, Trane, Lennox, Rheem, Goodman, York, and the other major names you'll find around here. For ductless systems, we see plenty of Mitsubishi, Fujitsu, and LG. Most fixes use universal parts we already carry, and brand-specific components can be sourced quickly when a repair calls for them.
Two things decide it: how old the system is and which part failed. A system under about 10 years old is usually worth repairing. Once it's past 15 years, or if the compressor or heat exchanger goes, replacement usually makes more financial sense, particularly with the efficiency improvements of new equipment. Our technicians lay out both numbers honestly and leave the decision to you.
In most cases, the same day. Emergencies like a dead AC or a furnace that won't light take priority over routine maintenance, and we'll tell you an honest arrival window when you call (805) 209-1677. Once our technician arrives, capacitors, contactors, igniters, and motors are already on board, so the majority of problems are fixed during that first visit.
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: removing the old unit, a properly sized new system, a clean installation, and a full test of every mode. You get clear quotes for both paths before you commit.
Yes. Our seasonal tune-ups clean coils and burners, verify refrigerant charge and combustion, test capacitors and safety controls, and check airflow end to end, with a cooling visit in spring and a heating visit in fall. It's the single most effective way to extend equipment life and avoid a breakdown in the middle of a summer heat wave or winter cold snap, and it often pays for itself in energy savings over time.
Absolutely. Mini-splits are a great fit for additions, garages, sunrooms, and older homes that never had ductwork. We size each zone to the room it serves, place the indoor and outdoor units carefully, and handle the line set, condensate drainage, and electrical connections properly. If central equipment is the better fit, we'll say so.
Check the thermostat setting and batteries, the filter, and the breakers for both the indoor and outdoor units. If the outdoor unit hums but won't start, or ice has built up on the refrigerant lines, shut the system off so the compressor isn't damaged and call us at (805) 209-1677. We'll get a technician moving your way right away.
