Heating
Heat that works on the coldest night of the year.
Furnace repair, heat pump installation, and emergency heating service across Orange County. Same-day diagnostics.
About heating
Heating service covers gas furnaces, heat pumps, and hybrid systems. OC winters don't get extreme, but when a cold snap hits and your heat fails at 2am, you want a real OC tech on the line — not a national call center. We service every major furnace brand and are factory-trained on heat pump installs.
When to call us
Signs you need heating
If any of these sound like your situation, give us a call or text. Many of these are quick fixes if caught early.
- Furnace runs but doesn't heat the house
- Strange smells when heat kicks on
- Pilot light won't stay lit (older gas systems)
- Yellow flame instead of blue (carbon monoxide risk)
- Heat pump iced over and not defrosting
- Furnace short-cycling or running constantly
- Heating bill jumped significantly
How it works
Our process, step by step
Quick triage by phone
Before we roll a truck, we ask basic questions. If it's a tripped breaker or wrong thermostat setting, we'll save you a service fee.
On-site diagnosis
We check the heat exchanger, ignition system, gas pressure, blower motor, and ductwork. CO testing on every gas furnace.
Honest recommendation
If your system is 15+ years old and the repair is over $1,000, we'll tell you replacement is the better long-term call.
Same-visit repair
Trucks stock common parts. If it's a special-order part, we get heat running with a temporary fix and schedule the permanent repair.
Why Coastline
What makes our heating different
- CO testing on every gas furnace service (safety first)
- Heat pump factory training (Mitsubishi, Daikin, Carrier)
- Available 24/7 in winter — yes, even Christmas Eve
- We service systems other companies refuse to touch (older gravity furnaces, mid-90s heat pumps)
Common questions
FAQ
- Should I switch from gas to a heat pump?
- In OC's mild climate, heat pumps now beat gas furnaces on efficiency and qualify for big rebates. If your furnace is near end-of-life, the math usually favors a heat pump.
- What's the most common winter call?
- Dirty flame sensor. It builds up carbon and the furnace won't stay lit. We clean it, you save a few hundred bucks vs. replacing parts.
- How fast can you get someone out at night?
- Average winter night response is under 90 minutes inside our core OC service area.
