What’s included in a Professional Furnace Tune-Up in Cary, NC – Part 1

As temperatures start to drop, it's time to schedule your annual professional furnace tune-up. Perhaps you've already turned on your furnace this fall, but for many of our customers, the furnace hasn't been touched since the Spring. With that in mind, today we'll discuss what's included in a professional tune-up in Cary, North Carolina and why it's so important to regularly maintain your HVAC system.

Why is it so important to regularly maintain your HVAC System?

Professional furnace tune-ups not only help prolong the life of your Cary HVAC system, but they also play an essential role in helping detect small problems before they turn into big, costly repairs.  We recommend that our customers get a professional tune-up twice a year (once in the spring/summer and once in the fall/winter).

But what's included in a professional furnace tune-up? Our furnace tune-up is a multi-point inspection of your system; and during the tune-up, one of our professional technicians will go above and beyond to make sure your furnace is in top working order.

Step 1: Check and Clean the Flame Sensor

One of the first things we'll check and clean as part of our multi-point professional tune-up is the flame sensor. The flame sensor is the part of your gas furnace that knows when the gas valve is open and a flame is present. If the flame sensor doesn’t register that a flame is present, it shuts the furnace off. Therefore, if you have your heat turned all the way up, but don't feel any heat, a dirty flame sensor could be the problem. Obviously, if it's dirty, we will clean it.

Step 2: Check and Monitor Indoor Blower Motor Amps

A pretty critical part of your furnace is the blower motor. This component pushes the heated air through your ductwork to warm your home. Then the amps on the blower motor are the electrical charges that power the blower. A common misconception is that more of anything is better, but that's not necessarily accurate when it comes to blower motor amps. Oftentimes, the blower motor can get over-amped which can cause your furnace to short circuit. This is another item we'll check on for you during your professional furnace tune-up.

Step 3: Monitor Inducer Motor Amps

In addition to the indoor blower motor amps, we'll also check and monitor the inducer motor amps. The inducer motor is the component that pulls cold air into your furnace in order for it to warm it up. This is an incredibly vital part, and without it, your furnace has nothing to work with. As such, we'll make sure it's properly running and set to the correct amp level.

Step 4: Confirm that Blower Wheel is Circulating Evenly

Another important element of your furnace is the blower wheel. The blower wheel ensures that warm air circulates throughout your home. While it's important that the blower motor is able to push warm air through the ductwork, without the blower wheel, you won't feel any of that warm air. In fact, if the blower wheel isn't working efficiently, you'll feel hot and cold spots. A professional furnace tune-up will make sure that your blower wheel is circulating evenly so that you feel warm air throughout your home.

Step 5: Ensure a Proper Burn from Furnace Burners

While we're pulling back the layers of your furnace, we'll also make sure that your furnace burners are able to get a proper burn. The burners are what warms the cold air that is brought into the furnace, using gas. If that part isn't working, your furnace won't be able to create warm air. It's an easy fix if it's not working, but it's something we'll need to check out.

Step 6: Make Sure that Capacitor(s) is Running Smoothly

Finally (at least for today), we'll make sure that the capacitor is working properly. The capacitor is what makes your fan motor work. If the fan is set to run, the capacitor will run a constant supply of electricity to keep the fan motor running. If it's not working, then the fan won't work, so it's a pretty important part and one that we'll take a look at during our visit.

We'll cover a number of other points during a professional furnace tune-up. Be sure to come back in another week to read more. Or, give Choice HVAC a call at 919-435-2711 to schedule your semi-annual appointment. We'd love to hear from you!
