The Ontario91764 calls we answer most often
If your system is doing any of the following, it is worth a diagnostic before the fault gets more expensive.
Pilot light or hot surface igniter failing repeatedly
Heat pump stuck blowing cold air in heating mode
Refrigerant leak at a flare or coil connection
One or two rooms that never reach the set temperature
Water pooling around the indoor unit or ceiling stains
Frozen evaporator coil or ice on the refrigerant lines
Heating and air conditioning service built around Ontario
We keep licensed, background-checked technicians on the road in Ontario and the surrounding 91764 service area, so a no-cool or no-heat call usually gets a same-visit fix rather than a return trip.
Around Ontario, condensate drainage is a recurring fault. Blocked drains and failed float switches cause more water damage claims here than actual refrigerant failures do.
We recommend two maintenance visits a year in California: one before May through October and one before November through February. It is the single highest-return thing a homeowner can do for equipment life.

Ontario91764 HVAC questions, answered
What brands do you service in Ontario?
All of them. Our 91764 technicians are trained on Goodman, Lennox, Mitsubishi Electric, Amana and essentially every other residential brand sold in California, including discontinued lines. We keep a broad parts catalogue on the trucks for exactly that reason.
Should I repair my system or replace it?
The usual rule of thumb: if the repair costs more than half the price of a replacement and the equipment is over ten years old, replacement generally wins. We will run that comparison with you on site and show you the maths — and if the honest answer is a $180 capacitor rather than a $9,000 system, that is the answer you get.
What causes water to leak from the indoor unit?
Almost always a blocked condensate drain line, a failed drain pan float switch, or a frozen coil melting faster than the pan can handle. In Ontario we see algae and dust clogging drain lines constantly during May through October. It is a fast fix but ignoring it ends in ceiling damage.
Do you service commercial and light commercial properties?
Yes. Around Ontario we handle rooftop packaged units, split systems, VRF/VRV installations and building automation faults for offices, retail, restaurants and multi-tenant buildings, including after-hours scheduling so you are not disrupting trade.
Do you charge extra for nights, weekends or holidays?
No. Our pricing in California is the same at 2am on a holiday as it is at 2pm on a Tuesday. Emergency calls are dispatched the same way as scheduled calls and carry no overtime premium.
Is my carbon monoxide risk something I should worry about?
With any combustion appliance, yes. A cracked heat exchanger can spill carbon monoxide into the living space, and it is odourless. We perform combustion analysis and a CO test on every furnace and boiler call in Ontario, and we recommend a working CO alarm on every level of the home regardless of who services your equipment.
