Signs That You Need Furnace Repairs

Monday, November 20th, 2017

chilly-manMention North Carolina to most people at all familiar with our country’s geography, and they’ll probably immediately think of hot, sticky weather. While that may be our reality for much of the year, what many people seem to forget is that the most intense heat of summer does not, in fact, last indefinitely. Truth be told, we have more than our share of uncomfortably chilly weather around here, especially on winter nights. Just because we don’t get hit by blizzards doesn’t mean that winter doesn’t come to visit.

That is precisely why it is so important that you keep your heater functioning at peak performance levels. The furnace is such a popular heater thanks to the fact that it functions very effectively and is, overall, quite reliable. The moment that you see any heater advertised as 100% reliable, though, is the moment that you should recognize an impossible claim. At some point, you’ll need furnace repairs. When you do, call in the Apex, NC HVAC pros on our staff.

How to Extend the Life of Your Furnace

Thursday, February 19th, 2015

Furnaces are the most popular kind of home heating system in the country, which makes their proper care and maintenance a pretty big deal for a lot of people. If you want your furnace to live as long and healthy a life as possible, there are a few different methods you can employ. Ideally, you should use all of them to make sure that your furnace has every chance to fulfill its potential. Let’s examine the things you can do to keep your furnace operating at peak efficiency for many years to come.

Change Your Air Filter

This is one of the simplest things you can do to prolong the life of your furnace, and yet most homeowners are completely unaware of the need for it. The air filter is a part in the furnace air handler, designed to capture dust and other debris that might blow in from the ducts while allowing air to flow freely. The air filter does its job well, protecting the furnace from particulates that could damage it. However, the air filter has no way of disposing of these particulates once it catches them. If not cleaned or replaced at least once every 1-3 months, the air filter can become clogged. This causes the air flow to be restricted, trapping heat inside the furnace and causing it to overheat. Overheating can do all sorts of serious damage to the furnace, most of which will shorten its lifespan. So, change your filter often if you want your furnace to keep operating properly.

Schedule Regular Maintenance

Most people avoid scheduling any kind of HVAC service unless they suspect that something is wrong with their system. While you should absolutely call for professional help if you notice an issue with your furnace, you should also schedule preventive maintenance at least once a year. Preventive maintenance has a multitude of advantages, from identifying and fixing potential problems before they start, to improving the efficiency of the system. Annual preventive maintenance is the single best thing you can do to ensure that your furnace lives as long as possible.

If you’d like to know more about extending the life of your furnace, call Raleigh Heating & Air to schedule an appointment. We provide furnace maintenance and repair services throughout the Cary area.

How Can I Tell How Efficient My Furnace Is?

Thursday, November 20th, 2014

Homeowners are more interested in energy efficiency today than ever before. Energy audits and blower door testing are now regular procedures to help homeowners find out where they can save money through improvements for a more energy-efficient home.

One of the major energy-consuming appliances in a house is its furnace. If you are concerned about saving money and lowering your energy use, it is important to know that you have a furnace that efficiently converts its fuel source into heating power with a minimal amount of waste. One of the best ways to ensure that your furnace in Raleigh, NC stays as energy efficient as possible is to schedule routine maintenance for it from professionals like those at Raleigh Heating & Air. Maintenance and energy efficiency are our specialties, so count on us to help you save money while keeping your home cozy throughout the winter.

The AFUE Rating on Your Furnace

There is a simple way to find out the energy efficiency of your home’s furnace: look at its AFUE rating. This number, which is found on the cabinet or in the user manual, is the “Annual Fuel Utilization Efficiency” measurement, and it tells you how well the furnace works at converting its fuel source (natural gas, electricity, propane) into heating power.

AFUE is a percentage that represents how much of the furnace’s energy source it converts into BTUs of heat. If a gas furnace on average turns 100 units of natural gas into 85 BTUs (as measured over a full year), then its AFUE rating is 85%. Currently, all furnaces produced in the U.S. must have an AFUE of 78% or greater; as of January 1, 2015, this minimum will rise to 81%. For a furnace to earn the ENERGY STAR label from the U.S. Department of Energy, it must have an AFUE of at least 90%. Some high-efficiency furnaces can score even higher than this.

You need to understand that a furnace’s efficiency rating will not mean much if the unit is malfunctioning, has a clogged air filter, dirty ductwork, or is not receiving professional furnace maintenance every year. Each year that a furnace misses its maintenance appointment from heating technicians, it will lose on average 5% of its efficiency, and that can mean steep increases in heating costs.

To make sure that your home’s furnace lives up to its AFUE rating, call on the heating and energy efficiency specialists at Raleigh Heating & Air. We offer maintenance, as well as duct cleaning, that will help keep your furnace in Raleigh, NC working in top shape and saving you money every year. Give us a call today to schedule an appointment.

Rust and Your Furnace: What It Might Mean

Thursday, March 6th, 2014

Here in Wake Forest, many people use forced air furnaces to heat their homes, which heat the air inside their central unit before blowing it through a system of ducts within your home. The system is cost-effective and easy to use, which is why it remains so popular. That’s also why it may be surprising to spot signs of rust in your furnace. North Carolina has its share of humidity, but for a system doesn’t use water, the presence of rust can be a significant concern. Here’s a brief rundown on rust and your furnace.

There’s no question that rust can be a serious problem when dealing with your furnace. It eats away at vital metal components, increasing corrosion and eventually necessitating replacement of the entire unit. If certain components, such as the heat exchanger, get rusty, it can constitute a legitimate threat to the safety of your household, since a cracked heat exchanger can release carbon monoxide and other toxic gases.

The good news is that it’s comparatively difficult for rust to get into your furnace.  Trace amounts of water vapor in the air should vent to the outside and not collect in your furnace, but problems with your ventilation system can led to some water condensing before it reaches the outside. Water can also get in form an external source, like a leak in your basement or water from a storm. The first one is rarely a problem, though the second can cause considerable damage. And even small amounts of water can wreak havoc over time, allowing the rust in your furnace to grow slowly over the years until you have no choice but to deal with it.

Understanding what rust and your furnace might mean is the first step to addressing the problem. The second is calling a qualified repair surface to locate the source of the issue and deal with it. If you need Wake Forest heating repair services, call the professionals at Raleigh Heating & Air. Contact us today to make an appointment and let us take care of that rust on your furnace.

Why Do Furnaces Need an Exhaust Flue?

Friday, February 7th, 2014

It’s a good idea to understand the basic components of your Wake Forest home’s heating system. Your heater is a vital part of your household, and it needs to function day in and day out. When problems arise, it can mean more than just going without heat. There are toxic gases involved, as well as flammable gases, and they can pose a danger if not properly handled. That leads to our question today: why do furnaces need an exhaust flue? In short, because it allows them to vent those gases safely.

With forced-air furnaces, the heating process starts when natural gas is ignited in the burners, creating a great deal of heat. It then has to get that heat safely into your home, and do so as efficiently as possible. So the burning gas passes through a heat exchanger – basically a metal tube with openings on either end – and the heat exchanger warms the air and allow it to be blown into the house via the ducts. The process leaves toxic gases like carbon monoxide behind. Obviously, you don’t want them entering your home. And that’s where the exhaust flue comes in. As the gases go through the heat exchanger, they are passed into the exhaust flue, where it can vent them safely outside the house. Very strict building codes govern where the flue can be placed, and in many cases a fan is used to help vent the gases, but its function is self-apparent. The exhaust flue ensures the safe functioning of the furnace and allows it to continue to do its job without making you home unsafe.

That leads to a second heating question: what do you do when there’s a problem with the exhaust flue? If you detect a clog in the pipe or similar problem, turn off the furnace immediately and call Raleigh Heating & Air. Call us today for any Wake Forest heating services you need!
