Why Your House Is So Cold—and What to Do About It

One of the top signs you need furnace repair in Visalia, CA is a cold house. More specifically, the furnace is on and appears to be working, but the inside of your house is still cold. The air takes way too long to get even a little close to lukewarm, or it’s not warming up at all. When the temperature in your house is nowhere close to what the thermostat reads or the temperature drops fast, yet the furnace is obviously operating and humming away, it makes you wonder what the problem is. Obviously, something is wrong. You may discover that your working furnace is running, but blowing cold air into your home. The good news is that there are a few things you can do to remedy this situation. Here are some suggestions. Check the air filter Your furnace may or may not have a unit air filter. If it’s a model that does require a filter, it has to be clean and free of debris in order to be efficient. A dirty filter will hinder the flow of air into your home and can cause the furnace to overheat. An overheating furnace will blow cold air into your home instead of warm air. Central heating and cooling systems use a separate air filter at the opening of the intake. This filter traps air pollutants—like dirt, dust, pet dander, fur, pollen and bacteria—so they don’t get recirculated throughout the rooms of your house. Test the thermostat Perhaps your furnace is running constantly, but the inside of your house is still uncomfortably cold. The reason for this could be that both cold and hot air are blowing into the house. Check that the fan switch on your thermostat is set to AUTO instead of ON. Leaving the fan on the ON setting can cause your furnace to keep blowing whether the heating cycle is on or not. This can have a negative effect on the temperature inside your house. Inspect the ductwork If your home is still cold even though your furnace is blowing hot air, the problem may be with your ductwork. Ducts that are leaky or damaged will let hot air escape and let cold air in. But it could also be related to a poorly adjusted or loose damper in the system blocking or reducing proper airflow. Schedule annual maintenance While there is a lot that homeowners and business building owners can do to care for and maintain their furnaces, unless you’re an HVAC technician, your best bet at owning a long-lasting, efficient furnace is to schedule annual maintenance. The majority of heating problems disappear after a good tune-up, which is a service that includes tightening components and testing function as well as inspecting and cleaning parts. Ask your HVAC tech what they’ll do during routine maintenance if you have questions.
