Modern furnaces are incredibly safe appliances with numerous components explicitly designed to enhance their safety and prevent dangerous malfunctions. However, this high degree of security means that many homeowners can take them for granted. While your furnace is unlikely to fail in a way that can cause harm, it's still crucial to recognize the issues that can be potentially hazardous. With gas appliances, these hazards typically take two forms: gas leaks and carbon monoxide leaks.

Knowledge is power, and that's never more true than when managing a large commercial structure. Understanding as much as you can about the systems that keep your building in operation can help you plan and prepare for maintenance and repair issues. When it comes to your heating system, few components are more critical than the boilers. Most modern structures use multiple boilers arranged in a parallel configuration. This design has numerous advantages that may not be immediately apparent if you aren't an HVAC contractor or a building engineer.

Central air conditioning is available in more homes than ever, and with rising summer temperatures, more homeowners are relying on it for comfort. If you're fairly new to having a central air conditioning system, it can be hard to determine when you might need to call an AC repair technician. All too often, early indications of trouble are overlooked due to a lack of understanding the system. Here's a look at some noises you might hear from your air conditioner that indicate you need an AC repair technician as soon as possible.

If you think that professional AC maintenance is a matter of preference, you may be setting yourself up for a number of HVAC issues. Perhaps you are in the group of homeowners who think that routine filter changing is enough to keep your AC system running optimally. There are a number of benefits you can expect if you get routine air conditioning service. The cost is likely to be less than the potential repair costs you might face by not getting maintenance.

Your air conditioning system is a huge investment in your home. The system makes your home a more comfortable place to relax, regardless of the weather conditions. With the huge amount you spend installing the system, proper maintenance is required to keep it functioning all year round. Air conditioning maintenance improves the efficiency and durability of the system. Therefore, you should perform regular maintenance.  Here are a few essential air conditioning maintenance services required.

Home heating systems can last for a long time, and there is a chance that you might not have replaced your older home heating system because it might still seem to be in pretty good shape. At some point or another, though, you will probably end up dealing with repair issues of some type with your older heating system, and you could be wondering if there is anything that you should know.

If your furnace won't turn on, the problem might be a bad draft inducer motor. When a draft inducer motor starts to go bad, you might hear unusual noises coming from your furnace. Once the motor fails, the furnace may try to start up a few times, but eventually, your furnace shuts down and won't start up again. You might be able to tell by looking at the control board codes that the problem is with the inducer motor.

The capacitor in your AC condenser gives the fan and compressor the power they need to start up. A capacitor is a fairly small electronic part, but it's important because when it malfunctions, the compressor in your condenser could be damaged as it struggles to start without a power boost from the capacitor. Summer is hard on your AC capacitor since the part is sensitive to heat. Here are two ways summer weather can damage a capacitor and what an air conditioning repair technician can do about the problem.

When you're building your new home, you have the option of either putting in a gas or an electric furnace. Your furnace installation will be done professionally by a licensed HVAC contractor—usually at the same time they install your air conditioning unit. Which is best for your needs: a gas or electric furnace? Your HVAC specialist will show you the benefits of each. One major difference between the two units is cost: an electric furnace costs around $395 or more, while a gas furnace costs around $1,360 or more.

If you're thinking of installing central air conditioning for the first time, consider having an electrical inspection done first if you live in an old house. You might need to upgrade your electrical panel so there is enough power for your new AC. Here are some things you may need to discuss with your electrician about an electrical upgrade. If Your Circuits Are Currently Overloaded If your lights dim when an appliance starts up or if the lights flicker regularly, you might have overloaded circuits already.
