Here’s When to Call for Emergency Heating Repair   

The Smell of Gas or a Gas Leak Warning 

Any sign of a gas leak is an emergency. Natural gas has an additive that smells like sulfur or rotten eggs to alert homeowners to problems. If you notice this odor, then leave your home immediately and call your gas company. Once the gas has been shut off and it’s safe to return, you can contact an HVAC company in Brea, CA to inspect your heating system. A cracked heat exchanger or a failing burner assembly can lead to leaks. Do not try to fix or inspect these issues yourself. A professional will have the experience and equipment to handle it safely.

Carbon Monoxide Detector Going Off 

Carbon monoxide is a colorless, odorless gas that can be deadly in high enough concentrations. If your detector is making sounds, it’s important to take the warning seriously. Get everyone out of the house as soon as possible, open the windows to let in fresh air, and call emergency services. After the immediate danger has been taken care of, you’ll need to schedule an inspection. Cracked heat exchangers and ventilation issues are common causes of CO leaks in furnaces. Routine maintenance can help prevent this hazard.

Loud Noises Coming from Your Unit 

Furnaces should operate with a low, steady hum. If you hear rattling, screeching, or banging, something inside your system isn’t working correctly. Different sounds can point to different issues:

• Banging: A delayed ignition might cause gas to build up and lead to small explosions inside the system.
• Rattling: Loose screws, panels, or internal parts might be shaking when the unit runs.
• Squealing and Screeching: A failing blower motor or worn-out belt could be the cause.

These noises won’t go away on their own, and waiting to loong to repair them can cause premature system replacement. If your unit is making strange sounds, a professional can provide a furnace repair.

Cold Air Blowing Instead of Heat 

Does your heater blow cold air? A faulty thermostat, clogged air filter, or malfunctioning ignition system could be the reason why. Leaking ducts might also be allowing heat to escape. If your system is running, but your home isn’t warming up, then professional troubleshooting is probably needed. You might need a repair if the issue is related to the heat exchanger or ignition.

Water Leaks Around Your System 

Have you noticed water pooling around your heater? This is not normal, and it could indicate a very serious issue. High-efficiency systems can produce condensation, which should be draining properly. If you notice water leaks, a blocked drain line or a cracked heat exchanger might be to blame. Ignoring leaks can cause mold growth, rusted components and electrical hazards. A quick response from a local HVAC company can repair the problem and prevent more serious issues from developing.

Turning On and Off Too Often 

Does your system turn on, run for a short time, then shut off before completing a full heating cycle? This can reduce energy efficiency, and put unnecessary stress on your system. Possible causes include a malfunctioning thermostat, a failed blower motor or overheating from clogged filters. Short cycling can eventually lead to a complete system failure, so it’s best to get it checked out sooner rather than later.

When Heating Problems Impact Your Health 

Heating issues will make your home uncomfortable, but they can also have a serious impact on your health and that of your loved ones. A failing heater can lead to poor indoor air quality that triggers respiratory issues, as well as unsafe humidity levels. It can also expose you to dangerous fumes like carbon monoxide. If you or your family experience dizziness, headaches, or breathing problems that get worse indoors, then your HVAC service in La Habra, CA system might be the culprit. An inspection can help identify whether your system is circulating pollutants or failing to ventilate.
