Common Central Heating Issues and How to Fix Them


HVAC systems have become an integral part of life worldwide, including right here in New Zealand. They help us stay happy and comfortable indoors all year round, at home and at work. However, like any other complex system, they can experience issues that hinder their functionality and comfort. It’s very important to understand when it’s time to call for central heating repair services.


One of the best ways to know when to call for help is to learn about the common issues that people face with their central heating systems. In this article, we’ll inform you about several issues that you may face with your central heating system and what you should do if they occur. 


Common Central Heating Issues That You Might Face


Here are a handful of problems that you might encounter with your system:


Uneven Heating And Cooling. Heat pumps have plenty of incredible benefits, with one major advantage of well-designed modern systems being even heating throughout your entire home or business. So, what do you do when some rooms are warmer or cooler than others? This uneven heating isn’t just frustrating; it could indicate that you need central heating repairs. 


This bothersome issue can be caused by several factors, including blocked vents or ductwork issues. If this happens to you, you can check the vents to see that they're open and not obstructed. Remember that you shouldn’t block your vents with furniture, decor or other objects if you want to maximise airflow and temperature control in your home. 


No Warm Or Cool Air. Naturally, the main purpose of central heating systems is to provide heating or cooling to your home. So, if your system isn’t acting as it should, that’s a clear sign that something’s wrong. This can be caused by a faulty thermostat, issues with the heating and cooling function or issues with the blower motor. 


Check your unit's thermostat to make sure it’s set to the desired temperature and functioning. You can look at the interface to see if there are any error codes or warning lights being displayed.


Weak Airflow. If your system is running but the airflow is weak, you may want to call for central heating repair services. Dirty air filters, blocked ducts or problems with the blower motor can cause this issue. 


Dirty air filters can be replaced, blockages can be cleared up and blower motors can be inspected if you encounter this problem. 


Unusual Noises. Strange, unorthodox noises are one of the most obvious signs that your heating system needs attention. These noises can include banging, whistling, rattling or other noises you don’t usually hear from your system. Heat pump units, especially modern ones, are well known for their quiet operation. So if yours is making loud noises, it’s a very clear indicator that there’s a problem. 


Check your system and vents for loose parts or obstructions that could be causing these strange noises when the system is operating. The airflow caused by the system could be causing objects to rattle or bump into one another, causing frustrating sounds. 


High Energy Bills. If energy bills are unusually high, you’ll want to find and fix the problem as soon as possible to avoid wasting energy and money. Unusual energy usage indicates that your system isn’t running efficiently. 


Dirty air filters blocking airflow and leaks in the ducts can cause inefficiency, as well as many other malfunctions. To prevent energy-wasting problems, you should have your system regularly maintained. 


Or, if your system is an older model, you can upgrade to a modern option to enhance your space’s energy efficiency.


When It’s Time To Call A Professional For Central Heating Repairs And Services


While some simple central heating problems can be solved by people who don’t have much experience, others should always be left to professionals. For example, if some of your vents are blocked by furniture, you can reorganise your home’s furniture layout yourself. However, if you don’t have experience or training regarding system repair, you shouldn’t attempt to replace a blower motor yourself. 


Complex HVAC issues should always be handled by trained experts who know what they’re doing. If you suspect that your system needs help, you can call trusty specialists to help you. Even if you can’t identify the exact problem you’re facing, you can have them inspect and maintain your units to be sure everything is alright. 


Although, you should note that you can call for assistance regarding any issues listed above, even if they’re common or minor. Handling your system incorrectly can be dangerous and can cause more problems.
