If you notice that there is something wrong with your heat pump or that it is not running smoothly, then you should contact a heating engineer without delay. The earlier you tend to the problem, the less money it can cost you. Leaving the problem to go on might also result in more damage to your system. If you find yourself in need of heat pump repair, do not hesitate to reach out for Let’s Heat.  

Here at Let’s Heat, we have the necessary experience and knowledge to fix your heat pump with ease and as soon as possible. We are trustworthy and excel at what we do.  

What are the most common heat pump repairs? 

1. Refrigerant Leaks 

A heat pump operates in a similar way to an air conditioner in the fact that it utilises the flow of refrigerant in order to move heat from one place to another. Whether it is summer or winter, refrigerant is necessary for the operation of your heat pump. That is why problems are expected following a leak. When there is a leak, your unit will not be able to transfer or absorb heat. This can damage the compressor and affect the operation of your heat pump.  

Our heating engineer will be able to seal up any leaks taking place in the refrigerant line and recharge the refrigerant. With this task done, your system will be running smoothly and effectively once again. Do not delay calling a heating engineer once you notice a drop in cooling or heating power. Hissing noise can also be a sign that you have heat pump troubles.  

2. Frozen outdoor unit 

The outdoor part of your heat pump works by releasing heat in winter and absorbing heat in summer. It is a common problem in winter that a layer of frost would form on the outdoor unit. That being said, your heat pump is supposed to run a defrost cycle in order to get rid of the frost. Too much ice building up can block your unit and cause serious issues.  

Calling a professional right away is important if you want to minimise the damage and prevent serious issues from happening. 

3. Reversing Valve is broken  

What allows your heat pump to reverse the flow of refrigerant is the reversing valve. This can allow you to switch between the cooling and heating mode. In some cases, this valve can fail and get stuck in one position. As a result, you will not be able to switch between the cooling or heating mode. A professional Let’s Heat engineer can easily replace a broken valve and get your system running again.  

4. Electrical Failure 

Your heat pump is powered by electricity. This electricity is used to power the compressor and the fan motors. That is why electrical failure could take place and are common. On some occasions, you would need to replace certain electrical parts. Without a doubt, a professional is needed to carry out these electrical jobs.

Signs Your Heat Pump Needs Repair

  1. Insufficient Heating or Cooling:
    • If your heat pump is not effectively heating or cooling your home as it used to, it could indicate a problem. This might be due to issues with the compressor, refrigerant levels, or other components.
  2. Unusual Noises:
    • Strange or loud noises, such as grinding, squealing, or banging, can be indicators of a problem. These noises may suggest issues with the motor, fan, or other internal components.
  3. Frequent Cycling On and Off:
    • If your heat pump is cycling on and off more frequently than usual, it may be a sign of a problem with the thermostat, a clogged filter, or issues with the system’s balance.
  4. Increased Energy Bills:
    • A sudden spike in your energy bills without an apparent reason could indicate that your heat pump is not operating efficiently. This might be due to problems with the compressor, refrigerant, or other components.

What kind of warranty is included with a heat pump? 

Almost all heat pumps would have some kind of warranty. The warranty terms would apply if the product has been registered within a certain time frame. To know more about the details of your heat pump warranty you should check with the manufacturer of the product.

When should I service my boiler? 

A well-maintained heat pump can last as long as 15 years. If not serviced regularly, that figure would be 5 years short. On top of that, your unit will not be performing well and might cause you more trouble or cost you on expensive repairs. 

The best time of the year to service your heat pump is before winter if you mostly use it for heating and before summer if you use it mostly for cooling.  

One of the signs that indicate if your heat pump is in need of servicing is when you start noticing an increase in your energy bills. When that happens, it might mean it is time to get your unit serviced by a professional heating engineer.  

You might say that you clean your heat pump regularly and therefore do not require servicing. This is far from being true. Cleaning and servicing are two different things. Filter cleaning is basic maintenance, but servicing involves tending to the mechanical operation of both units (indoor and outdoor). 

What are the benefits of servicing a heat pump? 

1. Improved efficiency  

Efficiency is one of the most important reasons why you should get your heat pump serviced. A smoothly running heat pump will save you money on energy bills because it will be using less energy. If your heat pump is not running at its peak, then it might cost you some extra money.  

Both the indoor and the outdoor units are prone to accumulate dirt and dust particles. This can prevent them from working efficiently as they would need greater power and more energy to either heat or cool your home. Cleaning or replacing the air filter can greatly benefit your unit as it will be working smoothly, and as a result, you will witness a reduction in energy consumption.  

2. Longer lifespan  

Just like any other device, a well-maintained heat pump has a longer lifespan and would usually last longer. So you will be making the best out of your investment.  

When minor issues are ignored or dealt with, they will cost even more to fix in the long run. What is more, they can shorten the lifecycle of your heat pump.  

3. Better comfort 

It goes without saying that if your heat pump is not heating or cooling as it should, it will, as a result, reduce the level of comfort you experience at home. 

4. Health benefits 

Servicing your heat pump on a regular basis has the benefit of helping your filter to keep removing bacteria or odours from the air in your home.

The average lifespan of a heat pump is between 10 to 15 years. Without a doubt, regular maintenance and annual servicing can help prolong your unit’s life and keep it working efficiently for as long as possible. 

Do heat pumps work in all houses? 

It is a misconception that heat pumps can only be used in a house with a garden. Almost all types of homes can be suitable for a heat pump.  

Are heat pumps a good investment? 

An air source heat pump is a wonderful option for all types of buildings and properties. A heat pump can provide a return on your investment if it is installed properly by a professional heating engineer. 

Is a heat pump better than an AC? 

With the exception of their initial high cost, heat pumps are considered to be better than ACs. They can operate as both an air conditioner and a furnace. So you will be getting two appliances for the price of one. What is more, heat pumps offer more comfort for both heating and cooling. Not to mention that they are more environmentally friendly.
