Here's something not many homeowners are aware of: their heating, ventilation, and air conditioning (HVAC) system is not only one of the most expensive components of their homes, it is also one of the most energy-hungry.
Maintaining the heating and cooling system is considered a must if you want your HVAC system to operate at peak efficiency at all times. Most HVAC mistakes that cause system inefficiencies occur during installation, maintenance, and incorrect operation.
Considering how costly it can be to buy, install, and operate an HVAC system, it makes perfect sense to ensure it lasts as long as possible. Unfortunately, many homeowners commit errors that can shorten their HVAC's lifespan and force them to call for HVAC repairs sooner than anticipated.
If you have an HVAC system at home, below are some of the mistakes you should avoid at all cost:
Tinkering with the settings constantly
People have various comfort levels. One temperature setting can be cool or warm enough for you, but it can be uncomfortable for other members of your household. In similar scenarios, household members will change the thermostat to suit their preferences.
Unfortunately, constantly fiddling with the settings can significantly affect your HVAC unit's overall efficiency and performance. If anything, HVAC settings should be stable. If you can't always agree on one setting, it is recommended that you consider installing a programmable thermostat.
With a smart thermostat, members of the household have the option to set the temperature they prefer for a specific time of the day when they are at home without tinkering with the settings constantly.
Improper placement of the thermostat
Just like air conditioning maintenance, the importance of installing the thermostat in the right place cannot be overstated. If you have a programmable thermostat and you place it in a spot where it gets a lot of sunlight or near air vents, it can give out inaccurate readings.
Ideally, thermostats should be placed in the center of your home. Avoid installing the thermostat near hallways, air vents, windows, doors, and kitchens, as well as areas that are regularly hit by sunlight, as it can cause your HVAC unit to work extra hard.
Not changing air filters
Cleaning or changing the air filters is one of the most straightforward HVAC maintenance measures you can make. The process is very simple: just take the air filter out, clean it, and put it back. Unfortunately, many homeowners forget or neglect to change the air filters.
Contrary to popular belief, HVAC filters are designed to do more than just trap and hold dirt, dust, debris, and other contaminants in the air. HVAC filters can also play a crucial role in ensuring your HVAC systems remain efficient.
If you don't change your HVAC air filter at least once a month, the accumulated debris, dust, and dirt can affect the airflow. This forces your HVAC system to work extra hard, so everyone stays comfortable. Over time, this can cause the HVAC system to function poorly. This can also result in reduced energy efficiency and higher energy bills.
Foregoing scheduled maintenance
This is something many homeowners are guilty of. Understandably, many homeowners forego routine maintenance because their units are working just fine. However, HVAC systems, just like anything mechanical, require periodic care to ensure it continues to function as efficiently.
HVAC condenser coils for one need cleaning. Thermostats need to be calibrated, and all the electrical parts also require tightening and inspecting, among other things. With regular maintenance, you can significantly lower the energy bills and avoid costly breakdowns. More importantly, you can help prolong your HVAC system’s life.
It is recommended that HVAC systems undergo routine maintenance and checks before the winter and summer months when they can be used heavily.
Holding on to outdated HVAC units
While HVAC units are designed to last a really long time, the efficiency and performance of outdated HVAC systems can eventually decline over the years. Most of the time, older HVAC systems will take longer to cool or heat a room. Ice buildup on the evaporator coils is also very prevalent in old units.
Old HVAC units also tend to be noisier. In addition, old models also have a lower Seasonal Energy Efficiency Ratio rating (SEER), which measures the efficiency of your HVAC system.
New HVAC units and models have higher SEER ratings. This means you will be able to save more on energy rather than holding on to your old HVAC system.
Conclusion
Operating an HVAC system can be expensive. Fortunately, avoiding the most common mistakes above can help ensure you won't have to spend more. In addition, it is also crucial that you have your HVAC system checked by professionals regularly. This is important so your system can function effectively and efficiently for many years to come.
