Refrigerant Leak

Refrigerant is a liquid that is vital to the cooling of the air from your AC unit. Refrigerants absorb heat, which then cools the air that is distributed throughout your home or office. Oftentimes, a leak in the line from the compressor to the evaporator occurs. This could cause your system to run more frequently as it tries to cool the air with less refrigerant. Your compressor may overheat due to this increase in use, and it could burn out. During the winter, ice can buildup as well on your lines and coils, but we don’t see that too much here in Punta Gorda.

Blocked Drain Lines

As your air conditioner works to drain off water from the evaporator coil from the cooling process, water can become trapped in these lines from the condensation that occurs. This can cause a backup in your AC system that can permanently damage your AC unit. Sometimes the damage is so great that your building is impacted as well.

Ventilation & Ductwork Problems

Sometimes the emergency HVAC problem we see is not in the heating and cooling units themselves, but instead in the transportation system, or your ductwork. Here, your ductwork can become clogged that will prevent heated or cooled air from being distributed properly throughout your building. The blockage is often caused by something big falling into your ductwork like insulation, a ceiling tile, or dirt that has accumulated over time. External blockages can also occur if something large is blocking the vents, such as furniture or equipment.

Electrical Problems

Both your heating and your cooling can experience electrical problems. The most likely culprit is a tripped breaker in your electrical panel. A fuse in your AC or furnace could be blown as well. A switch, or a contactor, can also be stuck one way or the other, causing your system to run constantly or not at all. These can also wear out, requiring a replacement.

Gas Leak

Gas leaks are the most dangerous type of 24/7 emergency HVAC problem we see. Leaks are often caused by a crack in your furnace system somewhere, such as the gas line. If you run out of natural gas if you are on a propane tank, this could cause an explosion. If you suspect a gas leak, call us for an inspection or your gas company as soon as possible.
