Top 5 HVAC Emergencies: How To Identify & Prevent Them In Your Home

When one of these emergencies happens, your HVAC unit won’t be able to generate cold or warm air. You might also end up in an uncomfortable and unsafe situation. This article will tackle five of the most common HVAC emergencies. This way, you can detect them immediately so that the issue doesn’t escalate into an irreversible one.

Heating System Gas Leak

You and your family are in danger when a gas leak happens in your home. It can lead to an explosion if you do not address it as soon as possible. A few things you can look out for are a whistling or hissing sound and the smell of sulfur or rotting eggs. When you think that your heating system is leaking gas, have it checked by a professional immediately.

HVAC Electrical Problems

An interruption in your HVAC unit’s electrical system can lead to various electrical issues. To start, make sure that the circuit breaker is switched on. Check the fuse box if you have one. If you have blown a fuse, replace it. Inspect the emergency shut-off switch as well. If you did all of these, but you are still experiencing electrical problems, call a professional. You might be having problems with the electrical contactor. Electrical issues could result in unheated or cooled air circulating in your home. This could be a dangerous situation to be in, especially if this happens during extreme weather.

Blocked Air Conditioner Drain Line

Condensation naturally forms during the cooling cycle. If it does not drain correctly, it can lead to water damage. The water can also overflow and cause damage to your walls, floors, etc. The drain line is responsible for releasing this condensation into the drain pan. However, algae, muck, and other types of buildup can cause a blockage. Some of the indicators of a blocked drain line are mold or rust in your system and high humidity in your home.

Negative Air Pressure

When too much air is pulled out of your home and not replaced, then it creates negative air pressure. The air might be pulled out via the crawlspace, basement, attic, and the gaps around doors and windows. Another culprit that creates an imbalance in air pressure are heating systems, such as fireplaces and furnaces. Your HVAC system, however, is known to be one of the most significant factors for creating negative air pressure inside your home.

A few indicators that your home has negative air pressure are unusually hot or cold rooms, or when you hear strange whistling noises. You might also notice the doors around your home suddenly opening and closing on their own, or the doors might get unusually stuck or too heavy to close. There could also be random air drafts around your house. You can solve this issue by ensuring that more air is drawn inside your home than what is forced out. Talk to a licensed HVAC contractor, such as Hart Home Comfort.

AC Refrigerant Leak

The refrigerant is an essential mixture in your AC’s refrigeration cycle. Unfortunately, the lines can weaken as time passes due to vibrations. Tears and holes can also cause the refrigerant to leak. A system that has a refrigerant leak won’t be able to cool your home effectively. You will notice that your A/C will release warm air instead of the cold air you need during the hot summer months.

A few signs that your cooling unit is leaking refrigerant include a hissing sound from the indoor air handler, a sudden spike in your utility bill, and frozen coils. Make sure to call a professional to help you as only a licensed HVAC technician can handle refrigerants.
