Reasons Why Your HVAC System Might Not Be Working Properly

HVAC systems are a great investment. More people are starting to buy them than ever before. When you consider rising global temperatures, it’s not hard to see why this is. HVAC systems give people the ability to keep their houses cool during heat waves. There are many other benefits to owning HVAC systems, too. If you are interested in getting yourself an HVAC system, you also need to think about maintenance. These units require a lot of maintenance. This post plans to explore this topic in more detail and will tell you about a few of the reasons why your HVAC system might not be working properly after purchase.

You Haven’t Hired Professional Support

Servicing your HVAC system is something you need to make a regular habit out of. You can hire a professional repair company to come and check your unit out, ensuring that it is running properly. There are lots of different types of maintenance that you can do independently, however, unless you are an expert in HVAC units, bi-annual service checks should be performed by professionals.

Your Unit’s Filter Is Dusty

Another common reason HVAC units fail is that their filters get dirty. Throughout your HVAC’s life, it will accumulate a lot of dust. It is your responsibility to clear dust out of your unit’s filter. In addition to dust clogging up and breaking filters, if there is an excessive amount of it this could be released into your house’s air, meaning you and your loved ones will be breathing it in. Mould commonly grows inside units that have not been cleaned properly. Make sure you clear away dust and mould.

Mould Hasn’t Been Cleaned Out

As mentioned in the previous section, mould commonly grows inside the ductwork of HVAC units. If you don’t clear it away, you could end up breathing in. Most types of mould are completely harmless, however, there are some that the body reacts very badly to. Some experts have theorised that a variety of mould, Stachybotrys chartarum, more commonly known as toxic black mould, is poisonous enough to be able to kill a human adult. Also, people with allergies or mould sensitives can have bad reactions to even the most harmless of moulds.

Thermostat Incorrectly Set

An extremely common cause of HVAC failure is an incorrectly set thermostat. Until your thermostat is properly set, it’s not going to work. For example, many report that their units are not blowing out cold air, but unit’s set to a warm temperature. Before you call a repairman or start taking your unit apart and looking for problems with it, check what the thermostat’s set to. Sometimes thermostats change on their own, so even if you set it to blow out cold air a few days ago and it’s now blowing out warm air, check it.

Damaged Heat Pump

HVAC units suck warm, stale air from your house up and then blow it outside. However, if your unit’s heat pump is broken, it won’t be able to get this air out of your house. That means it could just end up recycling and blowing stale air around. If your unit is blowing out hot air, this could be a cause. If your heat pump is broken it will either need to be repaired or replaced. You will most likely need to enlist a professional’s support if your heat pump needs working on.

Remote Control Batteries Not Working

Another common reason why people’s HVAC units stop working is because their remote-control batteries have not been changed! If you primarily use your unit’s remote to control it and not its console, check if the batteries need changing. Calling in an HVAC repairman can be very expensive. You need to do everything you can to avoid repairs taking place, which you usually can by performing routine maintenance. If your unit doesn’t seem to be responding, pop the batteries out and change them. If it does not work even after this, see if anything else here applies.

Your Coils Are Dirty

Another reason your unit could not be working is because its coils are dirty. Dirty coils are also the perfect places for mould to grow. If you suspect your coils are dirty, go out and take a look. Alternatively, hire a cleaning service to come in and do the work for you. Such services are seldom expensive.

If you plan on buying an HVAC unit in the near future, do your research first. Learning how to diagnose problems yourself can save you a lot of money. If you do not know how to clean or repair or even maintain your unit, hire a professional to do it for you.
