3 Common HVAC Emergencies You Should Know
HVAC repairs are always a problem that you should address quickly to maintain your home's comfort. However, some HVAC problems are more urgent than others, and it's important to be able to recognize HVAC emergencies. Here are three types of HVAC emergencies that every homeowner should be prepared for.
1. Clogged Condensate Drain Lines
Your air conditioner's indoor evaporator coils collect condensation because they are much colder than the surrounding air. Your evaporator coils are installed above a condensate drain pan that collects this moisture and transfers it outside through the condensate drain lines.
If the drain lines become clogged, you could have an emergency on your hands as the water in the condensate drain pan begins to overflow and pool around your air handler. To avoid water damage, you should flush the drain lines at least once per year to prevent clogs.
2. AC or Furnace Won't Turn On
If you've ever been stuck without a working furnace or air conditioner when you need them, you know how quickly the temperature in your home can become unbearable. One of the first causes you should consider when you have no heat or air at all is an electrical problem. Check your electrical panel for a blown fuse or tripped breaker.
In addition to your main electrical panel, you should look for a 240-volt shut off switch near your outdoor condenser. This must also be set to the on position for your air conditioner to run. If you are still without heat or air after these checks, you will need a technician to inspect your system for warn out components and other points of failure.
3. Gas Leaks
If your home is like most in the US, you probably have a natural gas furnace. Natural gas is an efficient and convenient fuel, but in rare cases, a gas leak can develop and backdraft into your home. Most of the time this occurs due to a clogged exhaust flue or a heat exchanger that has cracked after years of use.
Natural gas has no odor, but an additive called mercaptan is used to give the gas that is delivered to your home a distinct "rotten egg" smell. If you suspect a gas leak, turn off your furnace, ventilate your home, and exit the home until you have your furnace inspected by a technician.
Knowing the signs of an HVAC emergency is essential to keep your system running efficiently and keep the members of your household safe. Contact experts near you if you are in need of emergency HVAC repair services.
