Your HVAC system works hard every single day. Ontario HVAC keeps it running with expert repairs, right-sized replacements, and maintenance plans built for local homes.
A broken AC or furnace doesn't wait, and neither should your service company. With technicians based around the Ontario area, we provide fast, reliable service and hands-on care from experienced pros who know the climate and housing stock of our region.
When the air conditioning quits or the furnace won't light, you need a technician who finds the real problem and fixes it the same day.
A dead air conditioner on a hot afternoon is the call we run most. The usual culprit is a small electrical part, a capacitor or contactor, that our trucks carry, so most AC repairs are finished in one visit. Every repair comes with an upfront quote and an honest opinion on repair versus replacement.
A furnace that won't light on a cold night can't wait until morning. Most no-heat calls come down to a dirty flame sensor, a failed igniter, or a blower motor, and our trucks carry the common parts to fix them on the spot. You'll get a clear quote first, plus a safety check of the combustion and venting while we're there.
Whatever your system needs, a quick fix, a smart upgrade, or a full replacement, our team covers it start to finish with workmanship that lasts.

A system pushing warm air in summer is the call we run most. Our trucks carry capacitors, contactors, and motors to restore cooling same-day.
AC repairIf the blower runs but the air never warms, or the unit clicks without lighting, the failure is diagnosable in minutes with the right tools.
Furnace repairEnergy bills creeping up while comfort drops means the system is working harder than it should, dirty coils, clogged filters, or failing motors are the usual suspects.
Maintenance & tune-upsR-22 refrigerant, rust on the cabinet, a compressor on its second capacitor, these are signs the smart money is on replacement.
System replacementYour ducts move the same air thousands of times a day. Years of dust, dander, and construction debris ride along until they're cleaned out.
Air duct cleaningA garage office, a converted attic, or that one bedroom the ducts never reached, a ductless mini-split solves it without tearing open walls.
Mini-split installationAn HVAC system never fails at a convenient time. We schedule fast, show up on time, and arrive with the parts to finish the job.
Experience is what separates a lasting fix from a temporary one. Our technicians have spent years reading these systems, refrigerant behavior, combustion, airflow, electrical faults, and matching the repair to the actual cause.
If a $40 capacitor fixes it, that's what we'll tell you. We quote repair and replacement honestly, with real numbers, and let you choose, no scare tactics, no pressure.
Lasting comfort comes from fixing the cause, not the symptom. We find why your system failed and shut that down for good, then back the work with a real guarantee.
For over 12 years, Ontario HVAC has been the go-to team for HVAC service in this part of CA. Our hometown technicians know the specific conditions that affect systems in this area, from the seasonal swings that work equipment hardest to the code requirements local inspectors actually check.
Every technician on our team is seasoned, background-checked, and trained across every major brand and fuel type. We build every quote around your home's actual heating and cooling load. When you need help, you deserve a team that knows your neighborhood, not a franchise dispatcher hundreds of miles away.

Every job runs through the same proven steps, so nothing gets missed and the fix actually lasts.
Ring (909) 310-0762 whenever it suits you. We'll talk through the symptoms, tell you if anything needs immediate attention, and lock in a visit time that fits your schedule.
Our technician tests the system, capacitors, motors, refrigerant charge, ignition, airflow, safeties, pinpoints the actual fault, and presents your options with clear, upfront pricing.
From swapping a contactor to setting a new condenser, every job gets the same standard: right parts, right sizing, right workmanship.

Speed matters when the temperature is climbing or dropping. This is the sequence our team runs through, from the moment your call comes in to the moment your system is running again.
Our team answers your call right away, gathers the information we need, cooling or heating, running or dead, any error codes on the thermostat, and gets you on the schedule, often same-day. We'll guide you on the quick checks worth trying first in the meantime.
Your technician shows up ready to work, not just to look. The common failure parts ride on every truck, so the visit moves straight from diagnosis into repair.
The fault is pinpointed, capacitor, motor, refrigerant leak, control board, or the compressor itself. Then, we complete the repair on the spot whenever parts allow, or quote the replacement with real numbers if the unit is done.
We don't disappear once the visit is done. We follow up to confirm everything is holding, and for systems in their later years we'll suggest the maintenance rhythm that keeps them reliable instead of surprising you.
"Another company quoted us a full system replacement. Ontario HVAC traced it to a failed blower motor and fixed it for a fraction of that quote. The tech said the rest of the system had years left in it. You remember honesty like that."
"From the estimate to the final walkthrough, the whole install was clear and professional. The crew wore shoe covers, put down drop cloths, hauled off the old equipment, and the final bill matched the quote to the penny. The new system is so quiet we barely notice it running. Highly recommend."
"Years of dust, pet hair, and who knows what else came out of our ducts. After the cleaning, rooms that never got air finally do, and my wife's morning allergies have all but disappeared. They showed us before-and-after photos of everything they pulled out."
