If your furnace won’t start or doesn’t keep your home warm, the problem could be simple or serious. Either way, it’s a good idea to have your heater checked by a professional. Here are a few of the most common furnace repairs that our technicians perform in the Sacramento area.
Repairs for Pilot Lights and Ignition Switches
Most heaters have electronic ignition systems rather than continuously burning pilot lights. If your furnace isn’t heating your home or if the pilot light keeps blowing out, there could be a problem with a dirty or damaged thermocouple or faulty ignition switch.
Combustion Adjustments to Prevent Carbon Monoxide
If your heater is setting off the carbon monoxide alarm, it’s time for a service visit. This toxic gas can enter your home through cracked heat exchangers or clogged vent pipes. Dirty fuel nozzles and burners decrease combustion efficiency. This produces carbon monoxide and telltale yellow or orange flames.
Air Handler Belt Replacements
The annoying squealing noise that your heater recently started making is probably caused by the air handler belt. Over time, belts may need replacement due to cracks or fraying. During annual service visits, we’ll inspect the belts, adjust the tension and lubricate motor components that aren’t self-oiled.
Preventing Overheating and Airflow Issues
During furnace maintenance visits, we often encounter airflow issues. If the fan runs continuously or if it won’t run at all, the limit switch could be defective. There could also be a problem with the thermostat. If your furnace shuts down before your home reaches the set temperature, replace the return filter. Clogged filters increase operating costs and cause overheating. For efficiency, make sure that the supply and return vents are open and free from obstructions.
If you’re having trouble after checking the thermostat, replacing the filter and resetting the circuit breaker, call Ecology Air Innovations. Our helpful staff members will be happy to schedule a service visit or provide more information about our furnace repairs.
