Ideally, everyone would be able to get any heating and air conditioning problems resolved immediately, but due to technician availability, this isn't always the case. Therefore, it's important to understand which HVAC problems are more urgent than others so you can hire a contractor for emergency service when it's needed. Here is an overview of three common HVAC emergencies so you can be prepared.
Clogged Condensate Drain
The condensate drain pan is located directly below the evaporator coils above your furnace and air handler. When condensation builds up on the coils, it drips into the drain pan and out of the drain through a line that leads outside. If the condensate drain becomes clogged, it is an urgent problem.
A clogged condensate drain is an emergency for two reasons. Firstly, the drain pan will start to overflow if the drain is clogged, which could lead to significant water damage around your furnace. To prevent this, many HVAC systems have sensors that monitor the drain pan water level and shut off the system when it's full. This is the second problem, however, as this means you will be without air until the clog is cleared!
Cracked Heat Exchanger
The heat exchanger is the component inside your furnace that transfers heat to the air. Natural gas is delivered directly to the heat exchanger for combustion. If a crack develops in your heat exchanger, as can occur with years of use, your home could be exposed to carbon monoxide and other dangerous fumes. A cracked heat exchanger is an HVAC emergency that can directly impact the health of you and your family.
Popping and Crackling Noises
There are several different problems that can cause unusual noises while your furnace or air conditioner is running. Having an understanding of what can cause these different sounds will tell you how serious the problem may be.
One particular sound to look out for is a popping or crackling noise. This could point to an electrical issue with your HVAC system that poses a fire hazard. If you hear any of these electrical noises while using your HVAC system, the system is likely unsafe to use until you have it inspected by a technician.
HVAC emergencies are a problem that no homeowner wants to deal with, but it is essential to recognize them for the safety and comfort of your home. Keep these tips in mind so you can call for emergency heating repair service when you need it most.
