Before the steady low temperatures of winter arrive, you should know if your heating system has any malfunctions that may impair it or even cause it to break down. The best way to know if you need to schedule repairs is to take the heater for a brief “test run” during a warm day to see if you notice anything wrong. Afterwards, arrange for the heater’s annual maintenance visit from an experienced HVAC service technician.
Below are three common repair issues that heating systems may need before winter starts. You can call Purl’s Sheet Metal & Air Conditioning seven days a week to handle any of these troubles, as well as to sign up for our Ultimate Service Agreement to handle maintenance. We are here for all your needs for HVAC repair in Fresno.
3 Common Heating Repair Issues before Winter
- Gas line problems: You don’t want to turn on a gas furnace at the start of winter and discover that the gas isn’t flowing to the burner. If during your test run on a gas furnace you discovered that the burner wouldn’t ignite, even though the pilot light or electronic ignition was working, than you probably have trouble in the gas line. As with any device hooked up to natural gas, you never want to attempt repairs on your own. Only trust to experienced professionals.
- Broken ignition/failed pilot light: Everything else in a gas furnace may be operating well, but if the pilot light will not remain on, or the electronic ignition has failed, nothing will happen. Dirt across the burner can cause a pilot light to keep going out, or not come on at all, and electronic igniters can fail for a variety of reasons. Repair technicians can clean off the burner or replace the igniter to restore the furnace’s operation.
- Low refrigerant: This is an issue with heat pumps, which use the circulation of refrigerant to provide both cooling and heating throughout the year. The refrigerant in the system will not “get used up” during normal operation, but leaking can cause the level of the refrigerant (its “charge”) to begin to drop, which will affect its heating ability and could also lead to serious damage to its components. Because this affects the cooling ability as well, you shouldn’t ignore a dip in air conditioning power from the heat pump during the end of the warm season, since this decline will carry over to heating mode. Professionals will locate the refrigerant leaks, seal them, and recharge the refrigerant to its proper level.
