If your heat pump requires repair, in all likelihood, you’re going to need one of these three repairs performed: a system cleaning, a refrigerant recharge, or a part replacement.
Because these repairs vary in cost and time to repair, you’d probably like to know which fix your heat pump will require. However, we’re not in the practice of prescribing a solution without first diagnosing the problem, so let’s take a step back and look at some common heat pump issues to help you identify which of the above repairs might apply to your situation.
How do you know if one of these repairs is necessary for your heat pump? Some common issues with heat pumps are:
- The heat pump won’t turn on
- The heat pump isn’t heating or cooling
- The heat pump is constantly running
At Four Seasons Heating and Air, we oversee training for all our technicians, so you know you’re getting an educated opinion on every repair. If you’re having problems with your heat pump, give us a call today to schedule an in-home estimate.
Heat Pump Won’t Turn On
Heat pumps are responsible for both the heating and cooling of your home. So, if your heat pump doesn't turn on, that’s a critical problem. If your heat pump doesn’t turn on, it could be due to a broken thermostat, capacitor, or reversing valve.
You’re probably familiar with your thermostat, the device on your wall that turns your heat pump on and off and displays the current temperature. If your heat pump won’t turn on, the first thing you should do is check to make sure the thermostat switch settings are “on” and appropriately set to “heat” or “cool,” depending on the season.
If your heat pump settings are correct, but your system still won’t turn on, there might be a problem with your thermostat.
A heat pump capacitor is similar to a battery. It provides the initial boost of electricity to your heat pump to turn it on and then provides a constant level of electricity to keep it running throughout its heating or cooling cycle.
Broken Reversing Valve
The reversing valve is what allows your heat pump to toggle between its heating and cooling modes by reversing the direction of your heat pump’s refrigerant. If your reversing valve breaks, your heat pump will stick in either heating or cooling mode, so it won’t turn on if you try to change the mode.
If your heat pump doesn’t turn on, you’ll likely need a part repaired or replaced by an HVAC professional.
Heat Pump Isn’t Heating/Cooling
Maybe your heat pump turns on, but it’s not adequately heating or cooling your home. If you’ve checked your thermostat settings and the problem persists, there could be several causes:
- A broken reversing valve (discussed above)
- A refrigerant leak
- A clog in your system
Refrigerant is what allows your heat pump to absorb warm air and transfer it either into your home (to heat it) or out of your home (to cool it). If you don’t have adequate refrigerant in your system, your heat pump won’t transfer warm air effectively.
The Environmental Protection Agency has indicated that refrigerant leaks of up to 30% of the total charge over a year are not uncommon. Suppose you haven’t kept up with professional maintenance on your heat pump, and you're also experiencing issues with heating or cooling. In that case, it’s a good idea to have an HVAC professional review your refrigerant level. They will refill, or “recharge,” your refrigerant level if it’s too low and identify the leak to prevent the problem from recurring.
Additionally, because heat pumps draw in household air through your ventilation system, they can become clogged by dust and dirt. Similarly, the outdoor unit of your heat pump can become clogged with leaves and other outdoor debris.
Clogs in your heat pump can reduce the amount of air drawn into and released from the unit, reducing your heat pump’s heating/cooling capacity. Additionally, debris can block airflow to your heat pump’s compressor, which regulates the movement of refrigerant throughout your system.
In summary, if your heat pump is not heating or cooling your home effectively, it might require a part replacement, a refrigerant recharge, or a system cleaning.
Heat Pump is Constantly Running
Not only is a constantly running heat pump annoying, but it can quickly get expensive. If you’re experiencing this problem, you’re probably eager to resolve it as quickly as possible, so we’ll keep things brief: if your heat pump is constantly running, it could be due to a refrigerant leak or a clog in your system.
As discussed above, refrigerant leaks will require a recharge by an HVAC technician, and the technician should professionally clean the clogged heat pump. For a more in-depth analysis of this problem, check out our blog.
