HVAC systems are among the essential facilities in all residential and commercial buildings, especially during this hot summer. Many people are not satisfied with the quality of their HVAC systems. This can be really frustrating during bad weather conditions. Consequently, you need to pay special attention to your home heating and cooling systems. Fortunately, almost all of the HVAC problems can be prevented easily. If you have a little knowledge of HVAC problems, you can take suitable action sooner and therefore reduce your issues.
Here are some critical HVAC problems you need to take care of before you face issues.
Hot water sediment
Having problems with hot water systems is the most common issue in homes. The main reason is the minerals in the water will split from the water during the heating process, and subsequently, sediment at the bottom or attach to the surfaces of your tank. You might have seen this process in your kettle. This is quite normal, and there is nothing to be worried about. The problem can also be exacerbated if you delay the regular service of your heating system. The sediment will grow and eventually will make your water heater stop working. Even if your system works, the energy efficiency of your heater will decrease, causing higher energy bills. To remove the sediment, you can call a plumbing company near you to wash your boiler and clean all the sediment. For example, if you live in Toronto, R & Z Plumbing is a great option with fair prices and high-quality services.
Thermostats are at the heart of all HVAC systems, and therefore, any malfunction can cause you many problems. Thermostat malfunctions are among the most common HVAC problems. When your thermostat doesn’t work properly, your heater/cooler won’t work efficiently and cause several issues, including wasting energy and low air quality. There are many different types of thermostats out there, from programmable thermostats to mechanical ones. Of course, fixing a thermostat or replacing it is not an easy task that you can do yourself. You need to call a professional team to fix the problem or replace the device with a new one. If you opt for falling film evaporator then you can avoid most of thermostat related issues.
Another problem regarding heaters/condensers is when they are dirty so that the heat can’t be transferred very well. If you feel uncomfortable with your cooler/heater and think that they don’t work very well. In these conditions, you need to check if the problem is with the coils. Unfortunately, debris and dirt can fill the coils and cause an efficiency decrease in your cooling/heating system.
Dirt can be the cause of many problems inside and outside of your coils. For example, your coil’s surfaces can be dirty, and therefore, the coil can’t have an efficient heat transfer. Both the inner and the outer surfaces of coils can cause severe problems. One good measure you can take is to clean your coils regularly, or otherwise, your system can stop working because the dirt can gradually fill the condenser/evaporator.
Dirt and dust can cause some other issues in your HVAC systems. One common problem is with your filters. It’s obvious that replacing filters on a regular basis can help your system and increase the energy efficiency of your HVAC system. Fortunately, this task can be done by yourself without a professional company. In fact, the cleaner you can keep your filters, the less energy your system will waste. Dirty filters can restrict the airflow rate and increase the load on your fans, leading to higher energy consumption and lower lifespan of the mechanical devices.
Ignition issues are a bit rare compared with other HVAC problems you might face. Short cycling, delayed ignition, and some other issues are ignition problems you can face if you don’t have regular service. Several factors might cause ignition problems. For example, the flame sensor is an important device that can become dirty and therefore fails to detect your furnace’s flame. This can cause your system to be shut down.
Another device that can lead to ignition problems is your burner. The burner should be completely clean so that your flame is blue without any turbulency. Also, you might face the problem of unnatural furnace noises. You have to distinguish between natural noises that a furnace should have and some dangerous noises.
Here are several types of noises you need to be worried about:
- Repeated clicking: compressor or control panel
- Loud pops or bangs: dirty burner
- Rumbling: continued burning
- Squealing: blower motor and bearings
- Loud humming: fan
- Thumping: unbalanced blower wheel
- Scraping: dry bearings
Ignitions are not the kind of problems that you can handle by yourself. So you’d better assign it to a professional technician.
Many people complain about the quality of their HVAC system. A common mistake that causes many of these HVAC issues is avoiding regular service by a professional team. In fact, if you get your system checked regularly, you will need more costly repairs. For example, almost all common furnace problems can be prevented if you have them checked by a plumbing company. So, try to have a scheduled service program for your HVAC system.
