Emergency Heating Repairs for Waukesha Homeowners

Man in Cold Waukesha County HouseWisconsin residents know a failed furnace in the dead of winter is not fun. A cold home or business is more than a temporary discomfort.

4 Steps to Take When Your Furnace Stops Working

What to Do When a Boiler Stops Working

Broken Boiler System in MilwaukeeThe first thing to check when a boiler stops working is the pressure. Look at the pressure gauge on the boiler to be sure you’re in the green zone – pressure too high or low can stop your boilers from working.

Next, take a look at the pilot light. If it’s out, you’ll need to relight it to get your heat working again.

While these are the two most common boiler issues, another to consider is a frozen condensate pipe. This occurs when severe cold freezes the water within your boiler. With Wisconsin's notoriously cold winters, sub-zero temperatures can lead to freezing water blocking the pipe and shutting down the boiler.

How to Handle a Broken Heat Pump

A broken or inefficient heat pump can leave you cold in your home. Just like a boiler, heat pumps can actually freeze given the right conditions. This can cause the unit to stop working until defrosted. Other important signs to watch for are:

If you notice these problems, request maintenance from Donovan & Jorgenson.

Carbon Monoxide: The Silent Threat

Carbon Monoxide Detector in West BerlinBroken heaters can lead to carbon monoxide buildup in your home. CO poisoning is deadly if left untreated. Any fuel-burning heater, like an oil or natural gas operating furnace, can expose you to CO. Typical symptoms include:

If you suspect a carbon monoxide leak in your home, get outside into fresh air immediately. You should see a doctor to treat your symptoms, as long-term exposure can lead to lifelong health problems. Depending on where you live, you’ll have to contact the police or fire department to confirm the leak. They will locate the source of the leak and shut off any appliances which may be contributing to the leak.

During repairs, any windows and doors should be left open to let the CO vent out. You might need an entirely new HVAC system or just a few repairs to the leaky area. Leaks often occur when a heat exchanger cracks due to age or overuse. Annual heater tune-ups from Donovan & Jorgenson can prevent CO leaks in the first place by keeping your HVAC system in good condition.
