Other signs include frequent short-cycling, odd odors, or leaks around the furnace. If your furnace stops working entirely, it’s a strong indication that it requires repair or replacement.
If your cooling system isn’t turning on, start by checking for a tripped switch. If the switch keeps tripping, it’s best to call a specialist for further investigation. Another common issue is rapidly adjusting the thermostat, which can temporarily prevent the system from starting. Allow the system 15 minutes to reset; if it still doesn’t turn on, there may be a more complex problem requiring a licensed technician.
If your cooling unit is leaking condensation, a common cause is a blockage in the condensate drain line. When the drain line is clogged, condensation can back up and start to leak. To resolve this, you should have the drain line cleaned. It’s also a good idea to get a complete system check to make sure there are no other underlying issues.
A sudden increase in energy bills is often due to your cooling or heating unit operating less efficiently. This inefficiency can result from missed regular maintenance, causing the system to work harder to cool or heat your home. An aging system can also contribute to higher energy costs. To prevent these issues, schedule regular maintenance to ensure your cooling and heating systems run at peak efficiency.
If your A/C is running but not producing cold air, several issues might be at play:
- Refrigerant Issues: There may be a refrigerant leak or the system might need a refrigerant refill.
- Obstructions: Debris or leaves around the outdoor unit can block airflow and affect cooling performance.
If you’re experiencing warm air instead of cool air, it’s best to have a technician assess the situation to diagnose and resolve the problem.

- Overflow Pipe: Ensure the water level in the tank is below the overflow pipe.
- Food Coloring Test: Add a few drops of food coloring to the tank and see if the water in the bowl changes color.
