Furnace, Heat Pump & Boiler Service in Ontario, CA

Ontario winters are mild, but nights can still drop into the 30s and 40s. Because heating systems sit unused for most of the year, dust buildup, worn igniters, and weak parts often show up the first cold night you turn them on. A quick service visit before winter helps you avoid that surprise.

Furnace Service

Our furnace service in Ontario includes cleaning burners, testing the igniter and flame sensor, checking the heat exchanger, and confirming safe venting. We repair and replace gas and electric furnaces of all brands. Learn more about our furnace services.

Heat Pump Service

A heat pump heats and cools your home, so it works almost year-round in Ontario. We recommend service twice a year, once before summer and once before winter. Explore our heat pump service in Ontario.

Boiler Service

Boilers are less common in Southern California, which makes it harder to find a technician who knows them well. Our team inspects, repairs, and replaces residential and commercial boilers. See our boiler services.

Heating Tune-Ups & Memberships

Our ALL PRO Membership includes yearly tune-ups, priority scheduling, and 15% off repairs. If your heater stops working after hours, our emergency heater repair team is available 24/7. Need a new system? We offer heater installation and financing.

Repairing Your Heater with Care

Our technicians know exactly what to look for when troubleshooting problems with your heater. From pilot light issues with gas furnaces to faulty sensors or motors, we can quickly detect the problem and offer a cost-effective solution to get your heating system operating perfectly.

We understand that a problem with your heater can be an emergency situation that requires immediate attention. That’s why we offer our customers total availability, operating 24/7 to help you when you need it most.

Heating Service FAQs: Ontario, CA

How often should I schedule furnace service in Ontario, CA?

How often does a heat pump need service?

Do heat pumps work well in Ontario’s climate?

Why does my heater smell like burning when I first turn it on?

Do you service boilers in Ontario?

What should I do if my heater stops working at night?

How often should I schedule furnace service in Ontario, CA?

Once a year, ideally in the fall before the first cold nights. Annual furnace service keeps the system safe, efficient, and less likely to fail when you need it.

How often does a heat pump need service?

Twice a year. Because a heat pump handles both heating and cooling, it runs far more often than a furnace. A spring and fall heat pump service visit keeps it efficient through both seasons.

Do heat pumps work well in Ontario’s climate?

Yes. Ontario’s mild winters are ideal for heat pumps, which heat efficiently when outdoor temperatures stay above freezing. They also replace a separate air conditioner, which can lower your overall energy costs.

Why does my heater smell like burning when I first turn it on?

A light burning smell is usually dust burning off the heat exchanger after months without use, and it should fade within an hour. If it doesn’t, or if you smell gas (rotten eggs), turn the system off, leave the house, and call for service.

Do you service boilers in Ontario?

Yes. We inspect, repair, and replace residential and commercial boilers. Learn more about our boiler services.

What should I do if my heater stops working at night?

Check that the thermostat is set to heat, the batteries are good, and the breaker hasn’t tripped. If it still won’t run, call (909) 500-8193. Our call center is available 24/7 for emergency heater repair.
