Heat pumps are becoming more and more popular in the Pacific Northwest. Our mild year-round climate makes a heat pump an ideal option for homeowners. Heat pumps provide both heating and cooling, allowing you to use it as a heating system in the winter and as an air conditioner in the summer.
But sometimes a heat pump won’t blow hot air when it’s in heating mode. What gives? There’s nothing more frustrating than a heat pump that won’t heat your home on a cold, rainy day. Here are 4 signs that you need heat pump repair in Arlington, WA.
Broken Reversing Valve: Why Your Heat Pump Isn’t Blowing Hot Air
The reversing valve is the essential piece that allows a heat pump to provide both heating and cooling. This valve controls the flow of refrigerant. The direction the refrigerant moves is what causes it to be able to heat and cool.
If the valve is stuck, damaged, or broken and the heat pump is only outputting cold air, this important piece could very well be the cause. This is actually a fairly common issue we see in heat pumps and luckily, this is a fairly easy fix for our team as we can switch it out for a new one.
Refrigerant Leak Issues That Stop Your Heat Pump From Heating
A heat pump essentially works like an air conditioner, using the same technology and relying on refrigerant to function. Just like when an air conditioner develops a leak and won’t output cold air, the same thing can cause a heat pump in heating mode to not output hot air.
Leaks can arise for the same reasons they occur in AC systems. These reasons include corrosion, worn-down seals or valves, an aging system, wear and tear, pinhole leaks, and others.
Unfortunately, this problem won’t get better on its own. It’s also dangerous to breathe in leaking refrigerant. Because it has no odor or color, you wouldn’t know you have a refrigerant leak until your heat pump shows signs of it such as when it won’t output any heat. Schedule service with us so we can repair this issue ASAP.
Clogged Air Filter Blocking Heat Pump Airflow
The first thing you should check when your heat pump isn’t putting out any hot air is the air filter. What was the last time you changed it or cleaned it? If it’s been more than a few months, this could very well be the culprit.
A dirty, clogged air filter will restrict how much air enters the heat pump to be heated. When there’s not enough airflow, your heat pump will struggle to put out hot air in the winter and cold air in the summer. Change out the filter for a new one to see if that fixes the problem, then change it every 1-3 months.
Miscalibrated Thermostat Causing Heat Pump Heating Problems
A miscalibrated thermostat is an easy fix for our team. Sometimes the thermostat becomes miscalibrated and is unable to properly read the temperature of your home. If it thinks your home is warmer than it actually is, it won’t heat it up properly.
Frequently Asked Questions
Question: Why is my heat pump not blowing hot air?
Answer: A heat pump may stop blowing hot air due to several common issues, including a faulty reversing valve, refrigerant leaks, a clogged air filter, or a miscalibrated thermostat. These problems can prevent proper heat transfer or airflow, making your system blow cool or lukewarm air instead.
Question: What is the first thing I should check if my heat pump isn’t heating?
Answer: The first thing to check is your air filter. If it’s dirty or clogged, airflow becomes restricted, which prevents the system from heating properly. Replacing or cleaning the filter regularly, ideally every one to three months, can often restore normal operation and improve efficiency.
Question: Can a refrigerant leak cause a heat pump to stop producing heat?
Answer: Yes, a refrigerant leak can prevent your heat pump from producing heat because refrigerant is essential for transferring heat. Leaks often result from wear, corrosion, or aging components. Since refrigerant issues can be hazardous and usually will not resolve on their own, professional repair is necessary.
Question: What does the reversing valve do in a heat pump?
Answer: The reversing valve controls the direction of refrigerant flow, allowing the heat pump to switch between heating and cooling modes. If this valve becomes stuck or damaged, the system may only blow cold air even when set to heat, which usually requires professional repair or replacement.
Question: Can a thermostat problem affect my heat pump’s heating performance?
Answer: Yes, a miscalibrated or faulty thermostat can prevent your heat pump from heating properly. If the thermostat cannot accurately read indoor temperatures, it may not signal the system to produce heat. This issue is often straightforward to fix with recalibration or replacement by a technician.
