Common Heat Pump Repairs Explained

Tuesday, December 15th, 2020

Heat pumps come highly recommended as energy-efficient heating and cooling systems that are ideally suited for climates like you’d expect in Jacksonville, Florida. These are reliable devices, too, particularly when installed by qualified HVAC technicians, and when serviced through routine maintenance. Even so, problems can arise with heat pumps, so let’s take a look at what heat pumps are, and the common types of issues and repairs you can expect.

What is a Heat Pump, and What Does it Do?

To understand some common heat pump problems and how they might be repaired, it helps to understand how these fixtures work. They’re surprisingly simple, usually made up of two components, which would be the condenser unit on the outside of the home, and an indoor unit that vents hot or cold air into the home.

Heat pumps serve as both heating and cooling units, and they are reversible as your need for heating and cooling changes throughout the year. In warmer months, you can set them to air conditioning, and the reversing valve will pump cooled air into your home, while in the cooler months, you can set the unit to heat. This works exactly the same as the air conditioning part of the process, but instead of removing warm air from inside the home, the pump reverses to compress the refrigerant, which heats the refrigerant and allows the pump to blow warm air over the refrigerant coils and into the home.

Common Heat Pump Issues

When it comes to heat pump problems, there are a few common themes. Some of these include:

  • The pump isn’t providing enough heat. As with many issues like this, when a heat pump isn’t heating enough, it’s time to call a technician right away because the problem could get worse—and it could get worse quickly.
  • Problems switching into heating mode. Heat pumps are designed to switch between heating and cooling, and if yours won’t switch from one mode to the other, then it’s time for repairs.
  • Unusual noises can signify a problem, so if you hear banging or hissing noises, you’ll want to schedule a diagnostic.

Common Ways to Repair a Heat Pump

Repairs depend on what has gone wrong with the heat pump, but just the same as there are common themes in heat pump problems, there are usually also some common fixes that are quick and easy for a qualified technician.

  • When the pump isn’t providing enough heat, it may be that leaky refrigerant lines need to be repaired. This is also a likely repair if the unit is producing unusual hissing sounds.
  • Banging sounds could signify that the compressor needs repair or replacement, or that a fan needs to be replaced.
  • When heat pumps won’t switch between heating and cooling, the most common causes are either a malfunctioning thermostat or a malfunctioning reversing valve—and both are issues that can be corrected by replacing these parts.

If you’re experiencing issues with your heat pump system, or if you’re considering having such a system installed, don’t hesitate to contact A/C Designs. We can help you save on repairs and new installations alike, and our technicians have the industry expertise to handle your concerns quickly.

Heat Pump Reverse Valve: How It Works

Thursday, November 14th, 2019

If your HVAC system has a heat pump, you already know that this term can seem like a misnomer: after all, in Jacksonville’s mild climate, the heat pump provides far more cool air than warm. This ability to produce air at a wide range of temperatures can be attributed to the reversing valve, a metal cylinder with a slide that moves back and forth to switch between the heating and cooling modes. Read on to learn more about the heat pump’s reversing valve and some signs that your valve may be in need of repair or replacement.

Even Florida’s balmy climate can go on vacation during the winter months, and many Sunshine State residents find themselves reaching for the thermostat when temperatures dip into jacket weather. If you find that your furnace is constantly cycling on and off or just doesn’t seem to be getting your home as warm as it normally does, you may be facing a heat pump problem.

Heat Pump Repair Basics: The Reversing Valve

Wednesday, November 19th, 2014

Heat pumps work very similarly to air conditioners except for one key way: they can also heat your home. How do they do this? With the help of a component called a reversing valve. The valve itself is fairly complex, but the result for you, as the homeowner, is that you have a system that can easily switch between heating and cooling. However, heat pumps run year-round, making them a little more prone to needing repair than other more seasonal systems. If you are need of quality heat pump repair service in Daytona Beach, call the people you can count on: AC Designs Inc.

How Does the Reversing Valve Work?

The reversing valve is a somewhat delicate component that has a pipe on the bottom and three on the top. The job of the reversing valve is to change the direction of the flow of refrigerant in your system; this is how the heat pump changes modes between heating and cooling. The valve has two settings within it: one is excited, the other is relaxed. The valve manufacturer sets which state stands for heating and which stands for cooling, so there can be variations between valves. What doesn’t change is that once a state is set for a specific mode – either heating or cooling – it stays that way for the life of the pump.

So how does the pump change modes? As the homeowner, you press a button on your dual-mode thermostat. This cues the heat pump’s solenoid, which is a low-voltage electrical component, to slide the valve in the opposite direction. As the valve slides, the refrigerant also helps the valve to change states between relaxed and excited, or vice versa. Once the valve has slid into the correct position, the mode has changed.

When the Valve Is Stuck

One of the most common problems that can develop with a reversing valve is that is can get stuck. It may become stuck in a specific mode or in between modes. If the valve is stuck due to a bad solenoid, the solenoid can be replaced; but should there be another problem causing the valve to stick, such as leaking refrigerant, the valve will need to be replaced.

Reversing valve repairs should only be handled by trained professionals. The valves can be complex, but more importantly, they operate with refrigerant, and you must be certified to handle refrigerant. The trained technicians at AC Designs Inc. can handle all types of heat pump repairs in Daytona Beach, so don’t hesitate to give us a call if you need help with your heat pump system.
