Your heat pump, like any other appliance, is bound to wear out over time. Regular care and maintenance will extend its lifespan as long as possible, but nothing lasts forever. Knowing the telltale signs that your heat pump is on its way out will give you plenty of notice that it's time to replace it, ensuring that your family is never left without heat when the weather in Portland gets chilly. Here are some of the most prevalent signs that it's time to replace your heat pump:

It's Age

In general, heat pumps lose a great deal of their efficiency after about ten years. If your heat pump is than ten years old, it's definitely time to replace it. No matter how diligent you are with maintenance, a new heat pump will be much more efficient and effective.

You're Hearing Odd Noises

You should be pretty familiar with the normal noises your heat pump makes as it operates. If you're noticing strange grinding or clicking noises, it indicates a problem. Depending on the issue at hand, it might be time to replace your unit.

A Spike in Utility Bills

One of the best indicators that your heat pump is working harder than it once did is to keep track of your utility bills every month. If you're noticing a major increase in your energy use but your lifestyle and energy consumption habits have not changed, it could be time to replace your heat pump.

Refrigerant Leaks

Heat pumps rely on refrigerant to facilitate the transfer of heat. If you notice refrigerant leaks, such as hissing sounds or oily spots around the unit, it's a serious problem that requires immediate attention. Refrigerant leaks not only reduce the efficiency of the system but can also be environmentally harmful and pose health risks.

An Increase in Repair Calls

 If you've noticed that your heat pump needs repair more than once a year, it's likely time to replace the unit entirely. In most cases, a new unit will save you money in emergency service calls.

Your Home is Cold

If your heat pump is having trouble heating a room as quickly or completely as it once did, it's time to consider replacement. Portland can get quite chilly; your family deserves to be comfortable in your own home no matter what the weather is like outside.
