Systems We Repair

AC Plus repairs the full range of residential heating systems homeowners rely on throughout Southern California:

• Furnaces — gas and electric furnace repair for ignition problems, airflow issues, and more; see our dedicated furnace repair page for furnace-specific detail
• Heat pumps — repair for systems that aren’t heating, cooling, or cycling correctly; see our heat pump repair page for more
• Dual-fuel systems — diagnosis and repair for combined heat pump and furnace setups common in higher-elevation homes

Whatever type of heating system you have, our technicians have the experience to diagnose it accurately. Older homes throughout the Inland Empire sometimes still have wall furnaces, floor furnaces, or electric baseboard heating, and our team is equipped to service these less common systems as well, not just standard central furnaces and heat pumps.

Common Heating System Symptoms

Most heating problems show warning signs well before a full breakdown. Watch for:

• No heat or insufficient heat — often caused by a failed ignitor, faulty thermostat, or clogged air filter restricting airflow
• Short cycling — the system turns on and off repeatedly without completing a full heating cycle
• Strange noises — banging, popping, screeching, or rattling can indicate loose components or a failing part
• Yellow or flickering pilot light — a sign of incomplete combustion that should be addressed quickly
• Rising energy bills — an aging or poorly maintained system loses efficiency over time, even with unchanged usage
• Uneven heating — some rooms stay cold while others overheat
• Frequent thermostat adjustments — needing to constantly change the thermostat to feel comfortable often points to an underlying performance issue

If any of these sound familiar, scheduling a repair before the system fails completely is almost always less disruptive and less expensive than waiting for a full breakdown.

Our Diagnostic Process

Before recommending any repair, our technicians take a systematic approach to find the actual source of the problem:

1. System inspection — a full visual and functional check of the unit, including burners, ignition system, blower, and electrical connections
2. Airflow and performance testing — checking output at vents throughout the home to identify where and how the system is underperforming
3. Component diagnosis — pinpointing the specific failed or failing part, rather than guessing or replacing components unnecessarily
4. Honest recommendation — a clear explanation of what’s wrong, what it will cost to fix, and whether repair or replacement makes more sense for your situation

We provide free, upfront estimates after this evaluation, so you know exactly what you’re paying for before any work begins.

Repair vs. Replacement: How We Help You Decide

Not every heating problem calls for the same solution. A few factors point toward one option over the other:

• Repair typically makes sense when the system is under 10–12 years old, the issue is isolated to a single component, and the unit has a clean repair history
• Replacement typically makes sense when the system is over 15 years old, repairs are becoming frequent, repair costs approach half the price of a new system, or there’s a safety concern such as a cracked heat exchanger

Our technicians will always give you a straightforward recommendation rather than pushing a replacement you don’t need. If replacement is the better option, our heater installation team can walk you through next steps.

How Maintenance Reduces the Need for Repairs

Many of the repair calls we respond to trace back to a small issue that went unnoticed for months — a dirty burner, a loose electrical connection, a clogged filter restricting airflow. Annual maintenance is designed to catch exactly these kinds of problems before they escalate into a system failure. During a maintenance visit, our technicians inspect and clean key components, check for early signs of wear like soot buildup or corrosion, calibrate the thermostat, and confirm the system is running safely. Homeowners who schedule maintenance before the winter season tend to call for far fewer emergency repairs than those who wait until something breaks.

If your heating system hasn’t had a checkup in the past year, pairing your next repair visit with a maintenance inspection is one of the most effective ways to avoid repeat problems.

What to Do While You Wait for a Technician

If your heat goes out unexpectedly, a few quick checks can sometimes resolve the issue before a technician even arrives:

• Check that the thermostat is set to “heat” and the temperature is above the current room temperature
• Verify the system’s breaker hasn’t tripped at your electrical panel
• Replace the air filter if it hasn’t been changed recently, since a clogged filter can trigger a safety shutoff
• Make sure the furnace’s power switch (often near the unit, resembling a light switch) hasn’t been accidentally turned off

If none of these resolve the issue, it’s time to call for professional repair rather than attempting anything further on your own, especially with gas-powered systems.
