HVAC repair can be a very confusing topic. There are a lot of moving parts and most people don’t know much about it.

For anyone that isn’t a client of ours, we hope this can help all homeowners feel more confident when speaking to any HVAC repair company. With just a little bit of knowledge, anyone can feel secure knowing they won’t be talked into parts or repair that is unnecessary. This month we’ll discuss the indoor portion of the system involved in basic HVAC repair in Spring Lake.
Let’s Start with the Basics
The indoor portion of a heating and cooling system, called the furnace, controls the heating of your home. The outdoor portion, or condenser unit that we’ll talk about next month, does the cooling. Most homeowners know where the furnace is located and what its basic function is. However, there are many moving parts in a furnace which means there is a lot that can go wrong. Knowing just a little bit about each moving part of your furnace can help you, which can help us, determine what is going wrong with your furnace if you have a problem. By having a small amount of information about your furnace helps to make it less scary which allows you, as a homeowner, to take a little more control of your furnace’s maintenance. This helps keep it running more efficiently, lasts longer, and reduce your energy bills and repair bills.
Your Thermostat Talks Directly to Your Furnace
In the winter, your thermostat will send a signal to your furnace when the air in your home is detected to be at the level which you set. One of the most important and easy things a homeowner can do to ensure proper functioning is to change the batteries in the thermostat when you change all other batteries like a smoke alarm or carbon monoxide detector. A furnace does not “create” air, it simply treats and circulates the air that already exists in your home.
First, you set your thermostat to the temperature you would like the air in your home to be. When the air reaches that temperature, the furnace is triggered by the thermostat. This turns on the pilot light for the burner in the combustion chamber which starts the heating process. Then, it begins to pull in cool air through vents in your home called return registers into the large portion of the furnace called the air handler. This is what many people would identify as the furnace itself. It is inside the air handler that all the magic happens.
One important thing to take notice of is that all your registers are open and clear of any obstructions like curtains or furniture. Also, it is not recommended to shut any vents in your home to “conserve energy” for the same reason. Check out Myth #3 in this article to learn why!
Air First has to Pass Through the Filter
Aside from changing the batteries in a thermostat, maintaining the air filter in your furnace is another easy step. Just as reduced air flow through vents can cause your HVAC to fail, a clogged filter can do the same. The purpose of the filter is to allow clean, dust free air to flow through the furnace. Without it, furnaces would shut down constantly from dirt and debris inside gears and electrical components. See our post on air filters to learn more!
HVAC Repair in Spring Lake Can Involve What Comes Next
Next, air enters the blower. This is a fan that pushes cold air through the furnace. It then helps to push that warm air all through your home. Cool air moves through the blower into the combustion chamber to be heated. As the air passes through this part, it absorbs the heat. Now it is ready to exit the system through supply registers. One last item that homeowners in a multi-story home should be familiar with is the damper. This is a door that directs warm and cold air to different areas of the home. In winter, for example, you want more warm air directed downstairs since warm air rises. Most non-manual damper systems will have a large lever with the labels “Summer” and “Winter.” Before you pick up the phone to schedule your HVAC repair in Spring Lake, make sure you have your dampers set right!
