Common Heat Pump and Furnace Issues

Monday, October 29th, 2018 at 11:00 am

gas-burnerHeat pumps and furnaces are categorized as forced-air heating systems. They heat air and then, using a fan, blow that air through your home.

These heaters have many similarities on the surface, and they even share some of the same heating issues. But when you start looking at their internal components, you’ll quickly learn that these two systems are very different.

In this post, we’ll go over common heating repair issues between forced-air systems while explaining how they’re not quite the same.

Leaks

Both furnaces and heat pumps can develop leaks. They can cause serious damage to your system, and possibly a huge hazard to the safety of you and your family. As soon as you notice the presence of either of these leaks, you need to call for heating repair in Phoenix, AZ.

Furnaces

We’ll get this one out of the way first since it’s so important: gas furnaces carry the risk of carbon monoxide leaks. Although they’re not common, it’s nothing you’d ever want to take lightly, as they can be caused by many things, such as a cracked heat exchanger or even a clogged air filter. Luckily, carbon monoxide (CO) detectors can warn you of this threat right away.

Heat Pumps

Heat pumps can develop refrigerant leaks. While not hazardous to your health, they can pose a threat to the life of the heat pump. A refrigerant leak that gets progressively worse can lead to compressor failure (and that won’t be cheap to fix).

Before that happens, you can expect several symptoms to arise. For one, your heating bill will be higher than usual. Then, the evaporator coil might freeze over, since the leak will prevent it from being able to absorb heat.

Air Flow Issues: Little or No Warm Air

When you turn on your heater, you’re expecting it to do one thing: blow warm air. If your heater is failing to do the main task it’s designed for, it could be due to many reasons (some of which are quite serious)

Furnaces and Heat Pumps

Both systems require an air filter. This helps keep dust and contaminants out of the sensitive components of the machine. However, when that filter gets full, it will restrict airflow. Not only that, but it can cause the previously mentioned issues of CO leaks or frozen evaporator coils. Make sure to change that filter regularly!

Furnaces

Airflow issues can often be due to the furnace simply not starting at all. Typically, this is because the pilot light or igniter has fell into disrepair. Regular maintenance checks will ensure that these components are clean and operating properly.

Heat Pumps

If your heat pump’s outdoor unit has frozen over, that could explain why you’re suddenly feeling cold air. Although heat pumps are programmed to deal with this ice by initiating a defrost cycle, the feeling of cold air shouldn’t last more than 15 minutes. If it lasts longer—or if the outdoor unit is completely iced over—then it’s time to call for repairs.
