If your furnace isn’t heating, you deserve clear answers before you schedule. Below are the most common furnace repair questions we hear, plus what it may mean and what to do next.
Do you offer same-day furnace repair?
When scheduling allows, yes. Call/text (760) 227-2828 and we’ll confirm the soonest available time. If you have no heat, we’ll prioritize getting you an accurate diagnosis and a clear repair option as quickly as possible.
What should I check first for “no heat”?
First, confirm the thermostat is set to HEAT and the temperature is set a few degrees above room temperature. Replace the air filter if it’s dirty and make sure supply vents aren’t blocked. If it still won’t run correctly, stop cycling the system and call—rapid on/off cycling can create more wear.
Why does my furnace turn on, then shut off quickly?
This is often a safety shutdown caused by restricted airflow (dirty filter), flame-sensing issues, or overheating. Sometimes it’s a simple cleaning or adjustment; other times it’s a part that’s failing. We’ll check airflow, temperature rise, safety limits, and ignition performance to find the exact cause.
Why is the furnace blowing cool air?
A brief cool draft at startup can be normal while the blower ramps up. If it stays cool, the burners may not be lighting consistently or the furnace may be shutting down on a safety. We’ll verify ignition sequence, flame signal, gas delivery, and airflow to confirm what’s happening.
My furnace is making a loud bang, squeal, or rattling noise — is that serious?
It can be. A bang can indicate delayed ignition, while squealing may point to blower or motor issues, and rattling can be loose panels or duct vibration. If the noise is new or loud, turn the system off and schedule service. We’ll isolate whether it’s ignition-related, mechanical, or airflow/duct related.
I smell something burning — should I shut it off?
A light dusty smell can be normal on the first heat cycle of the season. If the smell is strong, electrical, or keeps coming back, shut the system off and call. We’ll inspect electrical connections, blower compartment, and heat exchanger area for safety.
How long do most furnace repairs take?
Many common repairs are completed the same visit once the problem is diagnosed. If a special part is needed, we’ll explain timing and options clearly so you can decide what makes sense. Either way, you’ll get a straightforward plan before work starts.
Do you recommend repair first or replacement first?
Repair-first. We’ll diagnose the issue, explain what failed, and give you heating repair options with clear pros and cons. If replacement is truly the better long-term decision due to safety concerns, repeated failures, or overall cost, we’ll show you the “why” and let you choose—no pressure.
Do you service all furnace brands?
Yes — we service most major brands and common control systems. Even if the unit is older, we can usually diagnose the failure and tell you whether repair is a smart move or if replacement is the better path.
Are you licensed and insured?
Yes. We are Licensed, Bonded, and Insured - Lic# 1066880.
