If your house doesn’t have a connection to the municipal natural gas supply, you probably use electricity to power most appliances, including the heater. The most common type of electric central heating system is the electric furnace, which works on the basic principle of electrical resistance heating. Electrical current flows through wires in the heating elements, causing the elements to heat up. The air sent through the furnace picks up heat from the surface of the elements and then continues into the ventilation system to the rest of the house.
It’s easy to explain—not much different from how a toaster works—but there are special components involved that allow an electric furnace to work reliably and provide precision home heating. We’re going to focus on one of them in this post: the sequencer.
What do you expect from your home’s furnace when you start it up for the season? Heat, obviously! But just plain heat isn’t enough, otherwise you could do well for a house with just a cheap space heater. No, you have a furnace because you want heat distributed throughout your house so all the rooms enjoy warmth. That’s the whole point of having a central heating system.

The fall brings relief from the heat and a time to prepare for the cold of the winter. It’s when our technicians get busy taking care of the heating system maintenance our customers need to make sure their home’s heater is in the right shape for problem-free comfort through the end of the year and the beginning of the next. 
October usually means we a break from the heat (although there are always those sudden turns—you can’t take cooler weather for granted until it’s truly winter!). As you get ready for the change in seasons to settle in, it’s a good time to evaluate the performance of your 
Air conditioning systems tend to need the most repairs during the last few years of their service lives. This increase in repairs is a warning an air conditioner is almost ready for a replacement. But there are some repairs that can occur when an air conditioner is still less than ten years old—and there’s one that can occur in an air conditioner that has only been in service for more than five years. In fact, it’s one of the more common AC malfunctions, and it’s a serious one.
“Wait, my air conditioner can overheat?” You might not immediately think of the air conditioner as an appliance that might overheat, but this is a danger for any mechanical device that uses motors. When your AC overheats, it will cause its circuit breaker to trip, the same as other electrical appliances in your house that are connected to the electrical system.
When the heat and humidity of late summer start their relentless assault on your home and your family’s comfort, you’ll be glad you have a powerful central air conditioning system to man the battlements and keep the invading heat hordes from storming the walls.
