If your heater suddenly malfunctions by blowing cold air during cold winter months, it can become a tiresome and hectic job to figure out exactly what and how to solve it. Elaborated below are some fixes and checks you can try before reaching out to a professional Heating repair Denver CO.
Check your thermostat
If your thermostat fan settings are set to ON, the air coming out might fluctuate as it controls the blower that circulates the air through your home. In that case, the blower will run regardless of the room temperature; therefore, ensure that the fan is set to AUTO so the blower only runs when needed.
If your thermostat is programmable, confirm the settings and inputs. If it runs on batteries, check if they are weak or dead.
Relighting the Pilot Light
- Light the pilot light by setting the thermostat from HEAT to OFF.
- Use your furnace manual to find the assembly and reset switch, which is usually under your furnace and needs furnace repair Denver.
- Wait for 3-5 minutes after turning the switch off, then turn it to “pilot” and press down the knob to restart the gas flow.
Bring a lighter to the pilot opening till the flame lights before turning the knob ON, and your furnace should ignite.
Clean the flame sensor
A dirty flame sensor may not be able to recognize whether your burners are on, which can prevent them from igniting and letting warm air in. Check the flame sensor to ensure it is clean and without debris.
Check the Air Filter
Due to accumulated dirt, air cannot pass smoothly through the filter, for which it will have to overcompensate, resulting in overheating. Cold air will be blown when safety sensors turn it off for safety reasons. Hence regular air filter replacements are essential.
Free the Vent From Blockages
Open all your vents and remove any blockages to the air vents that disrupt the flow of air, which leads to overheating, a similar reaction to clogged air filters.
In case of blockages in the PVC pipeline, there may be water pooling around the furnace, causing the furnace to shut down. High-efficiency furnaces condensate water that is drained out, but this water retreats to the furnace in case of blockages, and to prevent water damage, an overflow kill switch shuts down the system.
Broken condensate pumps also cause condensate overflow, which calls for professional assistance from Denver HVAC Contractor.
Ring Up Your Utility Company
Various possibilities can cause the utility company to cut your heat, missing payments, or have faulty transmissions, which can easily be solved by ringing up your provider. After verifying that you have no payments due, you may ask for technical help to inspect the issue. Similarly, confirm the same with your connection provider.
