Feeling cold, especially in your home, is a miserable feeling. A furnace that blows cool air has several possible causes, and the sooner you understand what the problem might be, the quicker you can warm up. Let’s look at some potential causes and the services that can fix or prevent them.
The brains of your HVAC system are the temperature controls. These devices use sensors that monitor the surrounding air. A thermometer starts and stops the furnace based on the input you provide. Problems can include:
- Wrong settings- The thermometer may have reset itself, or the temperature settings may have accidentally changed. You can adjust the thermometer to see if it fixes the problem.
- Malfunctions- Electronic failures and poor wiring can cause issues, especially with DIY installations. Heating services and repairs, commercial/residential HVAC maintenance, and annual preventative care are services DANDI HVAC offers to identify and fix thermostat issues.
Another common problem that can cause your furnace to blow cold air is a clogged or dirty HVAC filter. These filters trap particles that can damage your HVAC equipment over time. You can replace a dirty filter, but how do you know if the replacement is best suited for your furnace and duct system? Was the dirty filter you are changing the right one?
The professionals at DANDI HVAC can identify and replace dirty filters when performing services like preventative maintenance or HVAC repairs. They will install a filter that keeps debris out but lets air flow properly through your home.
Air ducts bring the warm air from the furnace to the rooms. If they are not working correctly, you will feel cold air blowing (or maybe nothing at all). Two usual culprits include:
- Leaks- Damage and age might cause a functioning duct system to quit working by allowing interior air to escape a crack or puncture.
- Blockage- There may be some blockage that prevents warm air from moving properly into a room or throughout the entire system.
Heating services, repairs, and preventative maintenance can identify and fix these problems.
The filters, thermostats, and air ducts are the usual suspects. There are other potential issues that professionals service and repair techs can diagnose and fix.
That includes issues with moving parts in your HVAC system (and the lubrication these might require), pilot light problems on older systems, mechanical failures, or perhaps just age-related wear.
An inspection and scheduled maintenance will identify problems, often before they cause problems. Your chances of having the furnace blow cold air are near zero if you have HVAC specialists examine your equipment.
