How Furnace Ignition Systems Work

Wednesday, March 19th, 2014

Modern gas furnaces use an ignition system to start up, a more complicated but safer way than the old-fashioned use of matches. When your thermostat sends the signal to the furnace cabinet that it’s time to burn the natural gas that will generate heat, the ignition system lights up the burners.

There are a number of different ignition systems you’ll find in furnaces today. Older ones have pilot lights, while newer ones use electronic igniters such as intermittent pilot lights or hot-surface igniters. We’ll look over these three in this post.

If you need repairs on your furnace or any other heating system in Fresno, call on the company that’s helped the Central Valley stay both hot and cool since 1952: Purl’s Sheet Metal & Air Conditioning.

  • Pilot lights: Also known as “standing pilot lights,” these have been in use almost as long as natural gas furnaces have existed. (In fact, the term “pilot light” goes back to colonial times and referred to a flame kept burning to restart a wood fire in a hearth.) During heating season, the pilot light burns using the fuel from the main gas line. When the thermostat signals for heat, a gas valve opens and sends gas to the burner, where the heat from the pilot light ignites the gas jets.
  • Intermittent pilot lights: Because pilot lights use energy as they burn, a more efficient system was developed where the pilot light would only come on when necessary. An intermittent pilot light uses an electrical spark to turn on the pilot light when it’s necessary to ignite the burner. When the burner turns off, it also turns off the pilot until it’s needed again.
  • Hot-surface igniters: These are now the most common ignition systems in furnaces, and allow for superior efficiency ratings in recent models. Hot-surface igniters do not need pilot lights at all; instead, they use a silicon nitride or silicon carbide surface that heats up as current passes through it, much like the filament of a light bulb. When the surface becomes hot enough, it ignites the burners. These electronic igniters need to be replaced every few years; usually technicians take care of this job during regular maintenance.

Speaking of maintenance… your furnace needs to have an inspection and tune-up once a year from an HVAC professional. With the Ultimate Service Agreement from Purl’s Sheet Metal & Air Conditioning, you’ll have two seasonal tune-ups each year (one for your heating, the other for your AC) as well as other benefits.

Treat your Fresno, CA heating system well: call Purl’s Sheet Metal & Air Conditioning for repairs and maintenance.

Why Duct Sealing Helps Protect Your Heating System

Wednesday, March 5th, 2014

Your duct system is attached to a centralized HVAC system and acts to move conditioned air throughout your home. Braches can sometimes develop in the ducts along the fitting of different sections, which can prove very costly to your system. Here in Madera, duct cleaning services can seal duct breaches for you, restoring your system to its optimum efficiency. But how beneficial is that?

Here’s why duct sealing helps protect your heating system:

Theoretically, the duct system should be completely self-contained in order to keep the conditioned air at its current temperature. When a breach occurs, one of two things will happen: outside air will get in or inside air will get out. In both cases, it will affect the conditioned air: making it warmer or cooler than you want it to be. That forces the HVAC unit to work harder to make up the difference, creating greater strain on the system and forcing your heater or air conditioner to spend more energy to do the same job.

Furthermore, a breach can also result in dust and debris getting into the system. Because of the nature of ducts, that dust will quickly spread to every corner of your home. That will lower the quality of the air and may exacerbate allergies in sensitive family members. In the worst cases, it might even create blockages in the ducts, reducing the flow of air.

Sealing the ducts can correct those issues. A trained professional will examine the ducts and either reconnect it or use a high-end patch to ensure that the leak is sealed. That maintains the integrity of the conditioned air and ensures that your HVAC unit doesn’t have to work any harder than necessary to get you the comfortable home that you need. It also keeps the quality of your indoor air high, reducing the risk of allergic attack and keeping your household cleaner. For more on why duct sealing helps protect your heating system, or to schedule a duct cleaning in Madera, contact the experts at Purl’s Sheet Metal & Air Conditioning. We’ll make sure the problem is fixed the first time, every time!
