Furnace Repair Across San Diego County
When your furnace stops heating, makes strange noises or keeps shutting off, you want a licensed technician who shows up, finds the real problem and tells you plainly what it will take to fix it. Cool Guys Home Services repairs gas and electric furnaces for homeowners across San Diego County, and same-day service is often available. Contact us to schedule a visit.
Signs Your Furnace Needs Repair
- No heat or weak heat. The furnace runs but the air from the vents stays cool or lukewarm.
- Furnace will not turn on. Nothing happens when the thermostat calls for heat, or the burners never light.
- Short cycling. The furnace starts, runs for a few minutes and shuts off again, over and over.
- Banging, squealing or rattling. New noises are usually a worn part or a delayed ignition, and they tend to get worse, not better.
- Uneven heat. Some rooms stay cold while others are warm, which often points to airflow or duct problems.
- Higher heating bills. A furnace that works harder to do the same job is telling you something is wearing out.
